Getting the most out of nvi
Hi, I'm interested in using nvi as my IDE for developing. I made a thread on the forum a while ago ( for those that are interested - http://forums.freebsd.org/showthread.php?t=34914 ), and concluded I would get a better response here. Since creating that thread I have gained a working understanding of how to use ctags and cscope, but I still don't think I have the most efficient interface possible. I'm very interested to hear how the developers here use nvi to code. One thing I'm really struggling with is full cscope integration with nvi and it's tags system. Basically, using :cs find will immediately open up the first result it finds, and I can't figure out how to bring up a list of all results in order to select the one you want to open up. Can anybody tell me how to achieve this? Alternatively, I could launch cscope from a shell within nvi (:!cscope blah blah), but this would open up a new session and start a new tag stack, so its not a very fluid way to navigate through source code. Any general tips on coding with nvi are welcome, even if they don't help my above situation. Kind Regards :) ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org
Dispersed storage solutions?
I recently came across a number of really interesting research papers about using erasure coding techniques to store data redundantly across a number of machines. This was pretty exciting for me because I have been looking for this kind of technology for a while. Simply replicating our data is way too expensive for us. I found a number of commercial products that provide this type of solution but they are too expensive for our business model. So ... has anyone used this kind of technology with FreeBSD before? If there isn't an existing project out there, is there enough interest to start one? This paper gives a solid overview of the technology http://www-bcf.usc.edu/~dimakis/RC_Journal.pdf Andy ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org
Question on io monitoring tools such as gstat and iostat
I am relatively new to using IO monitoring tools and wanted to confirm I understand them correctly. If I specify an interval of 5 seconds, my assumption is that the data displayed is an average over that 5 second interval. Is that correct or am I misunderstanding how intervals work? Thanks!

Ways to promote FreeBSD?
After using Linux for almost 15 years, I only recently started using FreeBSD. I own an internet startup and was looking for a solution for implementing large-scale storage servers. In my research I found ZFS and subsequently found FreeBSD. As I learned more about it, I was incredibly impressed. There are so many elements of FreeBSD that I love, I've completely ditched Linux and am deploying FreeBSD exclusively on my company's server infrastructure. I can't help wonder why I hadn't heard all about it before. Sure, I knew the name, but I had never seen it in use, either in college or in over ten years as a software developer since then. In contrast Linux is everywhere! Even though there are so many applications where FreeBSD seems to be a better or at least more mature solution. What are the current efforts to promote and educate people on FreeBSD? I'd love to help spread the word. -- Andrew Young Mosaic Storage Systems, Inc http://www.mosaicarchive.com/ Twitter: @MosaicArchive Facebook: Mosaic ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org
freebsd network problem and restarts
Hi ! Lately after install of new hardware, I upgraded to FreeBSD 7.0 AMD64. Problem is that every few days (5 or so) computer network connection is lost, if I restart computer everything is OK again What I need is script that will determine if connection is valid and if not restarting the machine. I plan to run this script by cron every hour... I am very lousy with writing scripts of anykind, so I would need little help from you... Script must do following things: 1. Check if connection is alive by pinging one site, www.google.com should be good example 2a) If connection is ok, script is finished 2b) There is no response following stuff must happen: a.) Wait for 10 minutes (or some specified time) and try step 1 again if fails following thing are done b.) Write line into log that connection is failed c.) Inject mail message to local sendmail instance (so that mail is sent after restart) d.) Reboot computer If someone knows about script that does this things, I would be very thankful if he/she could help me. If not I would be thankful for any help in creating such script. Thank you in advance. Andy ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
[NEW PORT] ports-mgmt/pkg - smart tool for managing FreeBSD ports
Hi all, I would like to present to you the new utility to deal with the ports system. The main goal of this project is to provide one common tool for managing ports and packages instead of relying on many applications (pkg_add, pkg_delete, pkg_info, pkg_version etc.). Actually it is a smart wrapper written in /bin/sh to the previously mentioned applications. It also uses external tool portmaster written also in /bin/sh by Doug Barton to work with the ports compiled from source. Pkg tool automates upgrading installed packages, outputs valuable information about packages/ports and overall simplifies working with the FreeBSD Ports Collection. It uses no external databases like portupgrade, just simplicity and minimalism are its main goals. You can test the latest version by installing the package from here http://home.si.rr.com/pyn/pf/pkg-1.1.tbz I commited pkg-1.0 with send-pr to the ports tree a few days ago. It is awaiting approval... http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/112572 Feel free to send any suggestions, new ideas and of course bug reports...

So back to problem. when I select packages install and FTP server (I usually use local, but today I also tried primaries and none of them has 6.1-RC1 on it. Then I tried options - any (instead of 6.1-RC1) and none of servers had any (they tried to load INDEX but it failed. Is there some problem there?

Poweredge 2850 keyboard problem
Hi all, Having googled for my problem, the only thread I can find is this one which doesn't appear to have a solution:- http://lists.freebsd.org/pipermail/freebsd-hackers/2005-April/011579.html I recently got two Dell Poweredge servers. A 1425 and a 2850. I installed 6.0-RELEASE onto both. With the 1425 I have no problem, but with the 2850 the keyboard fails to work at all. Some details; The keyboard is plugged into the standard purple kb input. It works fine when setting up bios options, perc4 controller set-up, etc. The keyboard works fine also if I boot into single user mode. However, if I do a normal boot into multi-user mode (the keyboard works fine when selecting a boot option) then when I get to the login prompt, no keyboard input at all. I tried a USB keyboard also. Same result, works ok for bios setting and single user mode but just doesn't work in multi-user mode. Oddly, the Dell USB kb I have also has a USB optical mouse connected to the keybd. When I plug in, I see the kernel messages popup on the console telling me a kb and mouse have been connected. The mouse works fine (pointer appears and can be moved and selection made) but the keyboard stubbornly refuses to do anything. Any ideas anyone? (I saw a thread somewhere that upgrading the kernel and world fixed it, however, I've cvsuped to 6-STABLE, new world and kernel and the problem still there. It's a dual processor system but same problem with GENERIC and a custom kernel. regards Andy ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

Network problem after upgrade from 5.1 to 5.3
Hi ! I am long time user of FreeBSD and for must updates so far I hadn't had much to do (maybe option here and option there, but networking never changes), but after upgrade from 5.1 to 5.3 everything stoped working. Since I couldn't rebuild kernel (some internal problems), I decided to delete everything and reinstal from scratch (last time I did this was when disk crashed, and that was about 5 years ago). But now again nothing works. I didn't change any configuration files since instalation except, rc.conf, and copied my firewall.conf and natd.conf... Even after recompiled I couldn't use network. My FreeBSD is used as server and also router for my internal network (using NAT). Problem: == If I disable firewall, natd is turned down so inside computers can't get to internet through FreeBSD box, if enabled, then nothing works.

Time problem...time is running very fast
Hi ! I have a very weird problem. Time is running very fast on my computer (arround 2 minutes per second - every second two minutes have passed. Some time ago I had the same problem with some other computer who had special Packet Radio card in it (which FreeBSD has no support for), but this time nothing special is in computer. I am running FreeBSD 4.4, machine is old Pentium I/ AMD 133, with two network card and graphic card (this graphic card is hercules(old)/vga). Does anybody have an idea where problem could be?

Re: Insider's scoop: Why FreeBSD is dying
Remember that Hotmail is a part of MSN, and they would have a need for that many IP addresses, what with their Internet content service. Andy At 03:48 08/18/2002, Terry Lambert wrote: Wow. I guess I'll address the most important point that hit home for me from that post... Examining the headers, it looks like Hotmail has a full class B (64.4/16); that's surprising. Why the heck do they have a full class B?!? If you are using load balancers for distribution, then you basically need only enough IP addresses to provide publically accessible VIPs to the various public services you export as seperate entities. There's no *way* they have 65,534 (subtracting out the unusable ones) of those! Seems to me, you could do all of Hotmail with well under a class C, if that. You could *probably* do it with a /28, which is the smallest BGP routable chunk UUNET supports. Does this seem odd to anyone else? Is Microsoft just an address space pig, or what? Do they consider the IPv4 address space as part of the company's valuation when making a purchase decision, or is this some legacy thing with Hotmail that no one at InterNIC bothered to correct, and they are just address rich by chance (this seems most likely, to me)? Inquiring minds want to know. Maybe it's just so that if a host gets RBL'ed or otherwise blacklisted, they can switch IPs, and won't have an interruption of email service to their customers? If that's the case, that implies the SPAM turnover on those things is on the other of one 65536th of the time it takes to get off a blacklist. That would imply they are sending an *incredible* amount of SPAM (obviously, that assumes a single VIP, which is really unlikely, but it's still within an order of magnitude, asuming a LocalDirector or other load balancer.

Re: dhcp problems with my ISP
Often, once the cable company sees a MAC address, it filters all other MAC addresses from getting a lease from your wire. This is true, broadly speaking. If they're mildly clueful (and probably if you convince them that you are), you may be able to get them to either add multiple MAC addresses for your account or simply relax the single MAC restriction if you explain that you're experimenting with new equipment/configurations you wish to use, and will be swapping equipment in and out (this is probably more likely with a static IP, natch). At least for some services, it's merely your local equipment that's caching the MAC address - e.g. for RoadRunner service, you can simply switch off the cable modem long enough to let the caps discharge completely (~30-45 seconds) and switch it back on, and it'll be happy with whatever it saw on it's ethernet port when the 10/100 link comes up, but you can't hot swap routers or firewalls and expect it to work - the link will come up, but the cable modem will be deaf.. :) HTH.

Re: dhcp problems with my ISP
Hi I have a Cable and have a Cable Modem for my internet connection of which you use dhcp to obtain an IP address great but this only seems to work successfully on a Windows machine I've registered all the other mac addresses of unix boxes and Apple macs I have and they seem to have alot of difficulty obtaining IP addresses. Especially the UNIX machines which run FreeBSD 4.5-RELEASE or 5.0-CURRENT on sparc64 at the moment the sparc64 box which is a Sun Ultra 5 which is the worst for detecting an IP with dhclient. On that hardware, you may be experiencing issues with auto-negotiation on the Happy Meal ethernet. Try nailing it to a fixed port speed, this may help. Or not. My Ultra-1 Just Will Not Work with some network devices, it is perfectly happy with others. Link link is not a reliable indicator. Sad but true. What I would really like to know is what does the windows dhcp do differently than say dhclient. Not much - most of what it does differently is due to the different ways in which you can interpret the protocol spec. However, note that almost all 'Doze DHCP clients behave differently to each other. Heh. See the RFC's for details, I think 2143 is the main one. The DHCP Handbook is well worth the money too. The ISC DHCP lists are searchable, and are frequently invaluable. I would be very interested to know as I would like a UNIX machine that can maintain and IP address. I've used my FreeBSD laptop with DHCP on many, many different networks, running ISC v2, many flavours of v3, M$ DHCP server, Lucent QIP to name a few over the last ~3 years, and I've never seen any issues with any of them where the server itself was functional (and I'd remembered to appropriately set the local firewall ;-). It maintains an IP just fine, except on networks where they have address churn on the DHCP server (usually due to lack of IPs in the pool). Try plugging a hub between the modem and the external interface of the firewall and sniff the DHCP exchanges on another machine (you don't need an IP address to sniff packets) - this may not show the whole picture, in particular it won't show what's being sent out the WAN end of the modem, but it's a start. If the DHCPNAK/DHCPACK packets aren't getting to the client (or bootp, DHCPREQ, DHCPINFORM etc. to the server), it can't ever work. If the server responds to a bootp/DHCP packet from the client, it's a reasonable assumption that it's seeing at least part of the traffic generated. Power cycle the modem, plug in the 'Doze box, repeat. Cheers, AS msg36093/pgp0.pgp Description: PGP signature
Re: dhcp problems with my ISP
Or broad-band-ly speaking? Yes, exactly... :-) ATT Broadband Internet will not give you a static IP or permit you to run a server (they have blocking hardware in place) unless you sign up for business service, which means you give them about four times the monthly fee vs. a home connection. Hmm. I don't see where the original post mentions any specific ISP - thus this is simply the policy of a single ISP, and not the one the poster is on? (In fact, it looks rather like the poster is in Dear Old Blighty... ;-) Given the current plethora of misconfigured proxies spewing SPAM, I have to admit I'm not as incensed by this as I might once have been. If you don't like this policy from your ISP, vote with your wallet. If you have no other choice in your area, then you have my sympathy. You could always move... :-d PacHell (and many other DSL providers) don't gouge you for a static IP, I'm happy to say. Their technical FAQ is also enlighteining on their need for a MAC address: http://www.bbs.att.com/faqstech.shtml . Hmm, I didn't actually find it to be so. Other than mentioning how to find your MAC on 'Doze box, I saw no reference to it at all. Perhaps I missed (or failed to intuit) something? Regards, AS msg36094/pgp0.pgp Description: PGP signature

MIB support for network devices in FreeBSD?
Hi all, (pls Cc: me on any response, not subscribed to either list) Can't find any references to this in the archives. What's the status of MIB support for network interfaces in FreeBSD? Is it deprecated, optional, would be nice? Reason for asking is that a dockapp I use has stopped displaying real-time stats since a recent upgrade. This is because the author has switched to using the interface MIB to collect statistics in the latest version[1]. Which in itself seems like a nice approach, except that it doesn't display anything for my 802.11 card, or the loopback device. Digging around a bit with grep (in 4.6-RC) shows that only 3 devices in /usr/src/sys/dev seem to have implemented full MIB support, a couple more increment error counters, and ~20 more NIC drivers (including most all of my NICs) don't apparently implement any support for MIB-based counters whatsoever[2]. Anyway, should the author of the utility be advised: a) Nice approach, little premature b) Nice approach, very premature c) Wrong approach, revert to previous if you want it to work with FreeBSD d) Other? Also, I'd be interested to know which MIBs we intend to support, and from which draft/RFC it's drawn from, if anyone happens to know or can point me at some *BSD docs? TIA. Regards, AS [1] He added FreeBSD support to a previously Solaris/Linux-only app, but doesn't apparently have a FreeBSD box to test on himself, asks for feedback on his webpage. [2] It's obviously not entirely that simple, 'coz I can't find any reference to the xl driver incrementing mib counters /either/, yet the monitor dockapp seems to work for the built-in xl device in my laptop... msg34905/pgp0.pgp Description: PGP signature
Re: MIB support for network devices in FreeBSD?
I believe you can get this info if you add the net/snmp or net/snmp4
port.
Hi Larry,
Thanks for replying.
Hmmm. I'm talking about code that uses a FreeBSD-specific sysctl to
interrogate the in-kernel if MIB counters, like this:
/* gather stats */
int
freebsd_sysctl_get(struct Devices*dev, unsigned long* ip,
unsigned long* op, unsigned long* ib, unsigned long* ob)
{
struct ifmibdata* drvdata = dev-drvdata;
int datamib[6];
int len;
*ip = *op = *ib = *ob = 0;
datamib[0] = CTL_NET;
datamib[1] = PF_LINK;
datamib[2] = NETLINK_GENERIC;
datamib[3] = IFMIB_IFDATA;
datamib[4] = 1; /* fill in later */
datamib[5] = IFDATA_GENERAL;
datamib[4] = IFMIB_IFCOUNT;
len = sizeof(struct ifmibdata);
if(sysctl(datamib, 6, drvdata, len, NULL, 0) 0)
return 1;
*ip = drvdata-ifmd_data.ifi_ipackets;
*op = drvdata-ifmd_data.ifi_opackets;
*ib = drvdata-ifmd_data.ifi_ibytes;
*ob = drvdata-ifmd_data.ifi_obytes;
return 0;
}
But these stats don't seem to be collected for at least some network card
drivers, presumably because those drivers aren't collecting those stats, e.g.
they don't #include net/if_mib.h, and thus don't allocate a mib structure or
increment any counters in that structure.
I can confirm that it definately doesn't work for the 'wi' and 'lo' drivers...
However, it definately seems to work for the xl driver...
Try this:
cd /usr/src/sys/dev; find . -exec grep mib {} /dev/null \;
'awi', 'ed' 'ray' drivers seem to have the most complete implementations,
but 'fe' 'xe' seem to have partial implementations (error counters only).
They're relatively short, so here's one by way of illustration:
./xe/if_xe.c:#include net/if_mib.h
./xe/if_xe.c:scp-ifp-if_linkmib = scp-mibdata;
./xe/if_xe.c:scp-ifp-if_linkmiblen = sizeof scp-mibdata;
./xe/if_xe.c: scp-mibdata.dot3StatsSingleCollisionFrames++;
./xe/if_xe.c: scp-mibdata.dot3StatsCollFrequencies[0]++;
./xe/if_xe.c: scp-mibdata.dot3StatsMultipleCollisionFrames++;
./xe/if_xe.c: scp-mibdata.dot3StatsCollFrequencies[scp-
tx_collisions-1]++;
./xe/if_xe.c: scp-mibdata.dot3StatsMultipleCollisionFrames += sent;
./xe/if_xe.c: scp-mibdata.dot3StatsExcessiveCollisions++;
./xe/if_xe.c: scp-mibdata.dot3StatsMultipleCollisionFrames++;
./xe/if_xe.c: scp-mibdata.dot3StatsCollFrequencies[15]++;
./xe/if_xe.c: scp-mibData.dot3StatsMissedFrames++;
./xe/if_xe.c: scp-mibdata.dot3StatsFrameTooLongs++;
./xe/if_xe.c: scp-mibdata.dot3StatsFCSErrors++;
./xe/if_xe.c: scp-mibdata.dot3StatsAlignmentErrors++;
./xe/if_xe.c: scp-mibdata.dot3StatsInternalMacReceiveErrors++;
./xe/if_xevar.h: struct ifmib_iso_8802_3 mibdata;
However, most of the drivers don't seem to have any code like this in them -
and at least some of those drivers don't work with the 3rd-party application
code above.
Should they? Or is this an older interface?
I'd like to advise the author so he can fix a very useful dockapp for me - or,
if this is the way to go, I'll badger Bill Paul to fix the 'wi' driver - oh,
wait a moment, maybe generating patches would be safer :)

Re: Can I get some comment on my RFC???
Terry Lambert wrote: Andy Sporner wrote: Hi Hackers, I would really like to have some input otherwise I might consider how usefull my participation on this list really is... Well, far be it for me not to comment, particularly if the lack of comments could hinder your future participation... I had the impression, thought it is rapidly diminishing that only certain people make impacts. I guess it is all about how to ask the question ;-) To me, this looks like a partial implementation of resource containers, with the ability to put each process into an arbitrary resource group If your need is to track all processes owned by init, which is what you say, then really, you are trying to solve a much smaller problem than the patches you give solve. It's possible I incorrectly stated the problem.I needed a container system to track an application (which might include daemon processes that normally attach themselves to init as a parent, or change their Group id) in a way they could not shake off the tagging. The idea was in the cluster software to guage how much resources (by walking the process table and adding up the resources (CPU for example)). This was to be used to find the best node to (re)start an application on failure of a node or on the initial start of the application. My initial approach was very static (no such patch) and it worked, but not well enough.For the sake of brevity, I wanted use the actual usage against the configured limit (a soft limit) to make decision on where to (re)start an application. I spent about 3 hours one afternoon in one of my better hacking moods putting this together. However, I think your patches are really very useful. Coming from you, I take high regard from this, thanks! Obviously, you could do this by GID, instead, if your different classes of demanding users ran under different default GIDs; and since an applicaiton could run under a GID via a single system call, and since it's required to make a system call to run under a different application ID... I'm not really positive that you've done anything that's really orthogonal to the default GID, in terms of providing additional information -- with the exception of the inheritance. That's the point, inheritance (and as I said I want this to be the stuff the process can not shake off it's feet--without knowledge of how). I would suggest that you restrict access to the cse_set_id(2) call. I would also suggest that you change it's name, and make it a mux system call: it's likely that people are going to find all sorts of things they want to do with the value of this; an obvious one will be getcseid, and another obvious one will be getpcseid (this latter is lacking for groups; thus your ID bears the same relationship to GID as UID bears to GID; i.e. it's an orthogonal credential value). I agree, I will do this. I also agree this this should be make as universal as possible. The only sticking point *might* be the other members of the structure that will be later used for process migration (as in Mosix). I have a working approach to failing over network sockets, though lacking in implementation. With this hardware device I am making that can switch the sheer number of trafic, I will use it as a front-end to a cluster and as part of the migration the registration of the endpoint will be changed on the front-end. On another point of usage, it could be a good way of tracking affinity of resources (as with process migration) so you don't have cross-node page fault wars (IE: Shared memory), so that if you move one process, you would have to move all in the group. I would like to start a dialog on this, but yes, I know the cluster list would be the right place ;-) BTW: CSE stands for (Clustered System Environment) so a name change would be very much needed to support a generic case. Perhaps the best thing is to split the patch into two and place the other members in another structure (since it is likely to grow) and perhaps if this patch is usefull it would be good to have it without having to have the clustering stuff too. *** Many other good points *** Thanks for your import--that was the goal of my 'RFC'. Now I have enough to go back and do some more work on it. I will post the new changes to my website later this week along with another piece of candy (graphical top), which was another piece salvaged from my clustering stuff. It's not clear if I will continue this clustering project for many reasons (mostly time related), days seem like months when I say I will put things out and I am sure there are those that think it doesn't exist at all. So this way I can do things more incrementally if at all. Best Regards -Andy To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

RFC- Kernel patches for process tracking (read more in body)
Hi hackers,
I had a need to track all processes including daemons that become owned
by init that started from a process for my statistics collection function of
my clustering software.
The basic idea is to add a structure to the 'proc' structure to keep current
and future data in and to be able to set (at least today) the application ID
into this structure via a shell command using a syscall().
Please give me comments on the patches.

Many other lists - like Yahoo! groups - have options like NOMAIL and neat ways to peruse messages online. With such improvements in place, anyone wanting to post could be a member without having to receive all that mail. I am not sure I was understood correctly. I while ago I was a member of an organization called HOSPEX. I think it is long since dead. In order for mail to be passed by the list server you had to be registered. IE: [EMAIL PROTECTED] would not be able to send mail because he was not a member. This doesn't solve the problem 100% because he could simply just register and then spam, but it does make it a little more difficult. The problem seems to be that people get lists of email reflectors (major domo's) and this makes their job easier for them to send their spam. If they are serious users then they won't mind registering, but the average spammer just uses a list and doesn't go to the effort. So the idea of online perusal and even sending mail from a web-based form would also work because it is not an automatic method, and thus likely not used by a spammer. This then makes it work good for everybody --even unregistered or mail-only users. Sounds sort of like a feature request--who does these anyways???

Andy Terry Lambert wrote: Robert Watson wrote: On Tue, 23 Apr 2002, Terry Lambert wrote: The reality is that reducing exposure is an important part of any security posture. This is an argument for security through obscurity. If we are talking risk reduction, then we can easily achieve it statistically through obscurity. In fact, this is exactly what FreeBSD does through its choice of TCP sequence numbers. Security by obscurity refers to a behavioral phenomena in system design and delivery, not to a technical design principle. For example, it refers to using a secret algorithm, but does not refer to using a secret key with a published algorithm. So disabling services in a default configuration reduces risk by reducing exposure, but it's not security by obscurity. However, if the goal is risk reduction, then securty by obscurity arguably reduces risk. When shipping third party code, or our own code, we accept that some code is more at risk than other code. That risk might be the result of complexity, privilege, exposure, ... Whatever the reason, it's disingenuous to sweep it under the rug (all our code is good, so we ship it all turned on) rather than select safe defaults and let people turn on what they need. This somewhat drops us into the What is UNIX? argument. I don't think you want to go there. Application state is not necessary for incoming connections which are self-identified by source and destination IP and port; the existing stateless firewall code can handle them completely, without introducing problems. X arguments that disable the X11 protocol over TCP will work regardless of the configured TCP port for XFree86. Firewall rules won't. Also, firewall rules may interfere with other applications, where X11 configuration won't. Both have their place. I can run sendmail on another port as well. At some point, you have to accept that there are Schelling points where policy and implementation can rendesvous. It's not reasonable to argue that an external mechanism is unusable because someone *might* start X11 with a different port. They *might* start it with the argument that reenables TCP. The coupling argument you are making here is specious: the default model for firewall protection is disable everything by default, and enable only that which is explicitly permitted. The point is that there is already a model for TCP service protection, and adding another frob on the side of each server for it really obfuscates the application of a uniform model to the problem. If we grant for a moment your argment complexity := vulnerability, then this increase of complexity is a problem, isn't it? Actually, it would be more useful to concentrate on so-called stealth firewall technology, so that OS identification due to port scans, etc., is impossible, and so it looks as if there is no machine there whatsoever, if there are no services actively listening AND access is permitted to the source machine. No doubt an interesting area to explore.

Re: C vs C++
C++ doesn't add noticable overhead and isn't slow, unless you are a dumbass about how you write it. All languages give you plenty of ways to write speghetti fortran code :-). C++ gives you a number of ways to obfuscate. I hate to enter such a fray, but I can pass on my experience working with a group of engineers porting an application. This was about 6 years ago, so perhaps they cleared up the semantics of the problem I describe. We had a revenue management application which ran very well on an HP-9000/G70 (a dual process PA-RISC machine). We moved it to an 18 processor Sequent machine and it dominated the machine. After investigation we found that the application code was spending 95% of it's time in Memmove. After even more investigation there was an argument of interpretation on semantics. The HP compiler passed a pointer as a reference to an object and the Compiler from Edinburg was actually copying the object (which was not small by any means). Such problems would be easy to spot in a regular 'C' program because it would render a compiler error. The point made about having competant experience with C++ is very well noted and I think the strongest argument. So put simply, ask the boss if he want's to add risk to the project because there is perhaps a lack of adequate experience in C++. If the boss has his wits about him (???) he should take the path that would be less risky--DISPITE his own preferences (unless he want's to pay more for well trained engineers).

Re: Porting a device driver from NetBSD to FreeBSD
that no sharing occurs. Otherwise I would get an interrupt for every network packet. This implies to me that: o It's a network driver o It works for a while and breaks o The FreeBSD operation is unexpectedly fast Together, this indicates that if you have the driver running and it locks up the system later, that you might be sharing an interrupt with your card, and that it might be your own interrupt routine which is treating someone else's interrupt on a shared interrupt as if it's your own, and breaking on that count. The much faster sort of implies that the other interrupt is causing your driver to poll your device, so the FreeBSD is faster effect you are seeing is just an illusion caused by the bad code. I can say in response: o No sharing of interrupts (that I can see in 'dmesg'). o There is no blocking to read the cause register of the crossbar. If nothing is set, we just leave immediately. o As to the much faster. It seems a different case. During initialization we read and write memory on the switch devices. This requires a PCI data transfer to send the command to the switch (to read the memory) and a response. We read every 64 words (16MB Ram) and it takes 3-4 minutes on NetBSD. The same code in the initalization routine on FreeBSD is so quick it almost cannot be counted. We also see this as an impact in establishing new connections, since establishing a new connection requires 16 words to be transferred to the switch memory. At least on Netbsd, interrupts are not enabled during the initialization (during attach (nitro_init)). so would not be subjected to the sharing of interrupt situation. Alternately, you could ask Bill Paul, since he's a better choice than me on this sort of thing, anyway. 8-) 8-). Hope this is useful, even if it doesn't come right out and say here's a patch. Fine enough! I have been *VERY* pleased at the response I have been getting in the FreeBSD world.

Re: Porting a device driver from NetBSD to FreeBSD
the the NetBSD counterpart (also boots MUCH faster!) on the exact same hardware (just swapped the boot harddisks). 2. The Memory test transfers high bulks of data using the same methods as the setting of entries to handle hardware forwarding of data. 3. Thus if Memory test is faster this follows that the setting of hardware forwarding entries must also be faster. You probably just didn't get to the right list or the right people. I was writting to tech-kern. I would wait weeks for responses. Being unable to drop details of your hardware can also mean that people will have to turn their diagnostic process over in the email message, and a lot of people are going to be a bit reluctant to do that, if they go by instincts, or if they consider it secret. Other people might not respond on the principle that the driver will end up being closed. We have a lot of kooks. ;^). :-) Agreed.

Hi Terry (and others!) You seem to know a lot about the kernel (as you always expand on my Cliff Notes versions of my answers). Can you give me any hints on the device driver question I posted a few days ago. There was a response, however I don't see how it applies for these reasons. 1. When the hardware (board) is inserted, but no kernel driver there are no failures. 2. When the hardware is installed with the minimal kernel driver the system locks. The minimal kernel driver only attaches some resources. 3. When doing the full initialization of the device (which works in NetBSD) there are also the SAME failures as doing no initialization at all of the hardware (as seen in the samples posted). 4. The device driver does not use MBUFS at all. Any ideas!?? :-) Thanks much in advance! Andy On 15-Feb-02 Terry Lambert wrote: Sansonetti Laurent wrote: Hi hackers, Is there a way to read user-land environ(7) table from the kernel for a given process ? Yes and no, or we'd already have implemented variant symbolic links. The problem is manifold: 1)The environment is pointed to by the environ ** pointer in the user process. The location of the environ ** pointer is not well known. 2)The environ ** value may be overridden by the user program entirely, so the pages where the data lives aren't where the are expected, so a saved pointer to envp *[] at execve time is not a workaround 3)The envrion ** is require by POSUCKS (sometimes spelled POSIX), so getting rid of it and making the getenv/setenv/putenv/unsetenv functions use a multiplex system call is not an option that maintains POSIX compliance. 4)It's hard to satisfy #2 and #3 and maintain binary compatability; the gross way you could do this is to save two copies of environ **, the real one at startup, and the shadow one called environ **, and then if the shadow does not match the real, fall back to the historical behaviour. Synchornizing means that you would need to know when the change happens (not possible, unless you catch a write fault and implicitly fix it up, like SVR4 does with page zero pointer dereferences, unless you specifically tune the kernel to fault fatally on them), or you would have to reflect all kernel level changes into the user space area shadow (expensive, but doable). 5)The execve() envp *[] passing is tricky, at best, for a modified implementation, since you have to read it back to pass it down. One option, which fails POSIX again, is to pass the default in if there is a NULL passed here, for an in kernel implementation (actually, you don't have to pass anything for the user environment, if the system and group contain everything you care about). 6)You can also put the environ ** into user pages (read only) that are also mapped into a pointer off the proc structure (read/write), so that the kernel changes are visible to user space. This makes it so that environ ** is not writable, but it is OK to read it, so a minimum number of changes are required for system/group/user logical names. I run with a variant of #6 on one of my machines; I use the same page I use for the environ ** for the pid, gid, and other data to make them zero kernel overhead for getpid, getppid, getgid, etc. -- basically, any system call that only reads a small fixed sized data value. This still means that the environment is stored in the user space process, but the current environ ** is always known to the kernel, and if it needs to be modified, it takes a system call. It's pretty cool: it lets me set the environment variables for processes from other processes, and everyone inherits from init's environment (system logical name table), the process group leader's (if they aren't the leader themselves: group logical name table) and then themselves, in increasing priority, on getenv(). But of course, it violates the writability of **environ, which POSUCKS wants, but I don't care (on that machine, signals default to restarting system calls so that my user space threads library is incredibly light weight, and getting the one-close-destroys-all-locks-even-for-other-opens behaviour is non-default, too... you have to fcntl(F_POSIX)). -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

ARP and AX.25 (help needed)
Hello Everybody ! I am working on implementation of AX.25 protocol. My code also needs ARP and I was wondering if there is a way to use existing ARP code, or do I need to duplicate code and use my arp structure instead original one? I need arp to resolve HAM addresses to IP addresses. HAM address has seven u_chars (6 for callsign one one for SSID). Now if anyone has any idea how could I solve this without duplicating same code, I would be very thankful. You can also contact me off-list.

Major number request
Hello, Software Technologies Group (http://www.stg.com) is currently developing a FreeBSD driver for SBS Technologies (http://www.sbs.com) for their WANic 520 series of WAN interface cards.

Re: Major number request
Actually, it will be a Netgraph node. The idea is to use the character device interface for configuration. Each of these cards has a 6-byte MAC address programmed into it which can be used as a unique ID for the card. We would like to be able to program the driver with an association between MAC address and card number (0, 1, 2, etc.). This card number would determine the name of the Netgraph node (e.g., wan520c0). It would seem that this configuration would have to happen before the creation of any Netgraph nodes, which means that some method other than Netgraph would need to be used to give the driver this mapping information (e.g., an ioctl using the character device interface). Another strategy occurred to me while writing this mail, namely that a default association could be made between Netgraph node names and physical devices which could be changed by issuing a control message to the Netgraph node. Perhaps this is a better alternative. I would welcome any suggestions you might have for handling this situation. Thanks again for your help...

Subject: ioctl and fxp/tl drivers
Hi all
This maybe a dumb question but a bit
stumped at the mo. When I make an
ioctl call to the fxp or tl drivers
thus:
if ((ret=ioctl(s, SIOCSIFLLADDR, (caddr_t)ifr)) 0)
syslog(LOG_ERR, ioctl (set lladdr): %m);
I get:-
ioctl (set lladdr): Inappropriate ioctl for device
Also, :-
ret = ioctl(fd, addF ? SIOCADDMULTI : SIOCDELMULTI, (char *) ifr);
if (ret) {
syslog( LOG_ERR, Can't %s on %s: %m
,addF ? SIOCADDMULTI : SIOCDELMULTI
,ifname);
}
I get:-
Can't SIOCADDMULTI on fxp0: Can't assign requested address
Also, when the call is SIOCDELMULTI (rather than ADD) I get
Can't SIOCDELMULTI on fxp0: No such file or directory
Same on the tl device. I've had a look in the driver source
and those calls appear to be supported. Can supply some debug
info if required but maybe the combined brains out there can
spot the obvious I'm missing?
tia, regards

RE: shutdown not completing
cross posting this to -smp and -hackers as it seems to be a problem there. for those who are new to the problem, in -stable we have reports of shutdown now hanging rather than dropping to single user mode. I have a dual PIII machine. At 4.2-RELEASE I had no problems at all. However, two/three days ago I went to -STABLE. I now have the shutdown now problem. However, if I boot GENERIC I have no problem with shutdown now. So, as an experiment I made a new kernel based on my SMP kernel. The only change I made was to drop the two lines which make it an SMP kernel. On doing shutdown now with this kernel I go to single user mode. So, the shutdown now problem appears to be connected with shutting down processor #1 ?? Anyone shed light on this?

The only issue is how does one set the delay... sysctl would work, I suppose, and one could introduce a general sysctl variable for screensaver standby mode timeout or something, and then all the other screensavers could be updated. Or it could be handled by the underlying screensaver driver, which seems to make more sense to me, although I don't know much about it.

I think it would make sense to both tell the VGA chip to blank (green_saver) and tell APM to shut down (apm_saver) with proper #ifdeffing around the APM stuff. I also think it would make sense to do this inside dev/fb/splash.c (or perhaps dev/syscons/syscons.c) instead of inside each screensaver, so that it's automatically handled. And maybe a new 'vidcontrol' option to set the blanking delay (as opposed to the screensaver delay) would be necessary.

The broken client is on the same subnet as the working ones and nothing in the server's ipfw ruleset refers directly to the broken client. - ad To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

Not really. The fact is that a user program can crash

Running ``nmap -sP 172.22.0.0/16'' as a normal user will cause a panic on
a recent 3.3-STABLE system :(

Could you be any less specific about the panic? Any sort of detail is
just going to make us want to fix it.
Here most of the message I posted to -stable:

Subject: nmap V. 2.3BETA5 causes panic
The system will panic with an 'out of mbufs' message when I run the above
nmap command ("ping scan" a class B subnet - my internal IP network).
Should this be happening when run as a normal user?? The kernel is pretty
stock with maxusers 32, no NMBCLUSTERS option, unneeded devices removed.
There is 64M RAM and 256M swap; it is has dual 90MHz P54C's.

How would you go about preventing this problem?
Thanks.

Subject: Re: maxusers/nmbclusters
I have read that if you have needs that would require turning up NMBclusters,
and certain sysctl options, etc, that you should do so independantly and not
increase maxusers up much above 256. Will that recomendation change with 3.2 as
well?
If you specify NMBCLUSTERS, then you only need to tune maxusers for
increased number of processes (nproc = 16 * maxusers). This is true in all
versions of FreeBSD.

A very nice, simple, explanation.
