That's still a bit counter-intuitive because in normal programming languages the binding order modifies side-effects via the evaluation order. And in both cases the evaluation order would be expected to be left-to-right, with -print running last. Yes. I'm actually talking rubbish. find evaluates its argument expression left-to-right, and the ``precedence'' actually applies to term grouping rather than evaluation order. (This does affect the outcome, but not in the way I glibly said it did). What I should have said is that like a lot of programming languages, find is lazy when it comes to Boolean expressions: when it gets a TRUE in an -or or a FALSE in an -and, the value of the whole expression must be TRUE or FALSE respectively, regardless of what the remaining terms are, so why bother evaluating them? (It's usually referred to as short-circuiting). I guess what you are saying is that the side-effect of print is based-on a Boolean running-value. And without the brackets, the first test has been evaluated, but not yet ORed into that running-value, by the time that print runs. That's not quite how it works. Rewriting find /usr/src -name Makefile -or -name '*.mk' -print using extra parens to emphasise the implicit grouping, and including the implicit -and, gives: find /usr/src -name Makefile -or \( -name '*.mk' -and -print \) in other words, an -or with two terms, one of which happens to be an expression. If -name Makefile is true, the -or is satisfied, so nothing else is evaluated, and find goes on to the next filename. Otherwise, the expression in the second term has to be evaluated. If -name '*.mk' is false, the -and is satisfied (which also satisfies the -or) and find moves to the next filename. If it's true, the -and can't be satisfied without evaluating the -print. The end result is that only files matching '*.mk' are printed. Rewriting the other case, find /usr/src \( -name Makefile -or -name '*.mk' \) -and -print If the first expression is false, the -and is satisfied and the -print is not evaluated. If the first expression is true (meaning either of the -name arguments is true), then the -and can't be satisfied without evaluating the -print. The last case is find /usr/src -name Makefile -or -name '*.mk' find quickly analyses this, finds no output action, and converts it to the second form above, internally placing parens around the whole expression and an -and -print after it.

Instant reboot with FreeBSD 6.3 and 2GB RAM
Hello, some users of FreeNAS which is based on FreeBSD 6.3 reported instant reboots on systems with 2GB RAM (most of them use 4GB). The reboot occurs right after displaying the FreeBSD loader menu. Most of them told me that they can boot if they reduce RAM to = 2GB. We are using the following kernel configuration which is based on GENERIC: http://freenas.svn.sourceforge.net/viewvc/freenas/branches/0.69/build/kernel-config/FREENAS-i386?revision=3291view=markup I found out another problem that causes a reboot on my 2GB machine. We are using a image for the LiveCD which is 64MB great. If i change back mfs_root size to 63MB all works well, but all above 64MB causes a reboot. Is there any limitation?

My application uses a raw socket so I was running it as root, which also uses the default settings. It mentioned that setting memoryuse is the same as setting both -cur and -max ; any ideas why memoryuse is saying it's unlimited even though it is not?

I have all the data below from these two applications. For malloctest, I can malloc as much as maxdsiz allows (without panic'ing the kernel).

Hi, I'm implementing a backup solution at work.We've bought a x86 server with two hardware raid 5 with for a total storage capacity of about 7Tb. For the software we are using for backups, the ideal scenario would be to have just one big disk so that no space problems would appear. I've tried to install FreeBSD 7 with no success, as it seems... the sysinstall tool doesn't support such big slices. I've read about the Large Data Storage on FreeBSD but I'm still confused.

The issue is the memory footprint for the application (osubw_sctpclien below) is quite large; on Linux it can be as much as 950 MB in resident memory, according to top. However, on FreeBSD I start to get ENOMEM always around the time my resident memory size is about 200 MB. I read a few posts and have seen people fixing their problems by adjusting kern.maxdsiz in /boot/loader.conf and/or by adding a swap file. I've tried both and for my application, it still seems to be limited to 200 MB resident memory regardless of maxdsize and swap file setting. I wrote a toy application (malloctest below) that calls malloc in a while(1) and breaks once it gets ENOMEM (doing another while(1) so it doesn't exit); this application's memory size in top always matches the kern.maxdsiz setting, however it has a very low resident memory number, according to top. Have a look at /etc/login.conf and the associated man pages. BTW, we've seen the exact behavior on FreeBSD 7 as well (6.3 was reported here). We've tried on different hardware as well, and keep getting haunted by this resident memory limit that we don't know how to set. Any idea why, in the data I originally reported, I can allocate kern.maxdsiz + swap (see SIZE from top output) for malloc(1 MB) in a while loop, yet the top value for RES is always really low? How come, in contrast, my application starts to report ENOMEM when SIZE is 203 MB and RES is 201 MB? This is why I titled the thread asking about an unknown (to me ;-) limit for resident memory... It's called memory overcommit. If the OS thinks it _might_ be able to get you the memory, it will allow it. You only actually use the memory when you start putting data in it (hence the difference between SIZE and RES) Add a statement to fill up the malloc()ed memory with some sort of data in your loop, and you'll see different behaviour. As to what's limiting your application, I'm not sure. What does the output of 'ulimit -a' say? Any other suggestions? brad Thanks for the prompt reply. This system has the default settings for all users set to unlimited for more or less all login.conf categories. I've pasted them below. My application uses a raw socket so I was running it as root, which also uses the default settings. It mentioned that setting memoryuse is the same as setting both -cur and -max ; any ideas why memoryuse is saying it's unlimited even though it is not? I tried explicitly setting -cur to 1000M and it still started giving ENOMEM around 200 MB resident memory in top... brad default:\ :passwd_format=md5:\ :copyright=/etc/COPYRIGHT:\ :welcome=/etc/motd:\ :setenv=MAIL=/var/mail/$,BLOCKSIZE=K,FTP_PASSIVE_MODE=YES:\ :path=/sbin /bin /usr/sbin /usr/bin /usr/games /usr/local/sbin /usr/local/bin /usr/X11R6/bin ~/bin:\ :nologin=/var/run/nologin:\ :cputime=unlimited:\ :datasize=unlimited:\ :stacksize=unlimited:\ :memorylocked=unlimited:\ :memoryuse=unlimited:\ :filesize=unlimited:\ :coredumpsize=unlimited:\ :openfiles=unlimited:\ :maxproc=unlimited:\ :sbsize=unlimited:\ :vmemoryuse=unlimited:\ :priority=0:\ :ignoretime@:\ :umask=022: root:\ :ignorenologin:\ :tc=default: -- Bill Moran http://www.potentialtech.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] -- Bill Moran http://www.potentialtech.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

RE: rc script REQUIRE-ing a service on another host
Jonathan McKeown: We had a power failure last night, and this morning I found that imapproxyd (running on a webserver which provides webmail) had failed to start because it depends on imapd (running on the mailserver, a different host), and imapproxyd had won the startup race. I need to prevent the race by making one service depend on another service running remotely. While I sketch out some horribly untidy fix, can the Lazyweb tell me if there is already a neat solution for this? I do not know if this is possible within the rc script itself. Have you looked into sysutils/monit (to monitor and restart a service like imapproxyd)? Nagios is probably overkill for this. Monit can be configured to check whether imapproxyd is running and restart it if necessary. Just make sure you do not make the monit rc script depend on anything running remotely. :-) -- Sahil Tandon NOTICE: If received in error, please destroy and notify sender.

Re: Large filesystems help/ideas
If you only have FreeBSD installed on the box or if you don't need slices/partitions you can just do newfs /dev/xxx (dedicate). vinum should not be used on 6.x and above, gvinum (GEOM + vinum) replaced it but I'm not sure if it's still actively supported/developped ..

FreeBSD has an equivalent program in ports/misc called ezload. I just
had to add one line to it to recognize the newer hardware and it works
like a charm. Annoyingly, the installed binary is called ezdownload,
so it took awhile to find the thing after it installed. Included is
the patch to add the line, tell me if you don't understand patches
(patch file.c file.patch) - basically just open it and add the line
that starts with + manually to the mentioned file - everyone always
assumes everyone with a *nix box is a super-hacker, and I sure ain't.
I tried pestering the ezdownload maintainer/author (can't remember
which) to add my patch and make a new release, but I never heard back.
Guess I will have to follow up on that - don't love patching 20
programs every time I bring up a new box, and I haven't heard of old
hardware in several years, making ezload pretty much irrelevant
without the patch - everything uses the fx2 cypress usb devices now.
I'll ask you a question in return - what software drivers do you use
with the m-audio stuff? I've got an m-audio UNO USB-MIDI dongle
I've never attempted to plug in - maybe you can point me in the
direction of the apps I need to make it go!

It works, but no drivers exist for the wireless or wired Ethernet ports. The wireless is a newer Atheros part and ath(4) should gain support for it, but I have no idea what the timeline will be. The wired Ethernet is an Atheros (formerly Attansic) L2 10/100, and I'm not aware of any concrete plans for a driver for it. I've used a Linksys USB200M USB ethernet (axe(4) driver) with mine and that works well. One of the guys I know is running FreeBSD on the Eee, and has written up the following information for anyone who is interested in doing what he did: http://nighthack.org/wiki/EeeBSD This includes tips on how to get the wireless working, and sound, and some oddities with how X11 works. Thanks for that hint. I'm thinking in buying such a device to have it with me as a typewriter, mostly; normally I use FreeBSD 7.0-REL on my laptop with around 200 compiled ports: KDE, OpenOffice, Lyx, StarDict, ... the compilation normally takes 2-3 days to have it all ready; of course, on that limited device with 4 or 8 GByte SSD it is not an option to compile the stuff up from /usr/ports on the system itself, not only from the point of view of disk space, but also because of the limited lifetime write cycles of the SSD; in short: what would be the easiest way to move the installed ports from my laptop to such an Eee PC? can I make, for example, packages from my ports and install them? Thx matthias [Sending this a second time to the list only, since it had too many recipients the first time and was probably rejected] I happen to have an eeePC and have successfully installed FreeBSD on it. It can be done in various ways (even without a CDROM, if you have an external USB disk). I can attest the instructions in nighthack.org work: Sound and wireless work fine. There are a few things you can do it to speed it up: - The SSD is too small for the classic partitioning scheme of FreeBSD. Probably a large '/' partition or a '/' and '/home' will do. Do not use swap. - Turn of logging (syslogd_enable=NO in /etc/rc.conf) - Edit /etc/ttys and reduce the number of virtual terminals. You probably don't need them. - Do not compile anything on the eee. It wil be a test of its abilities and your patience. Compile the kernel on another a PC and copy it via a USB key. Either use ready made packages (possibly after setting PACKAGESITE to packages-7-stable) or use 'make package' on your main pc to create packages and transfer them. - The eee will happily run X and any environment you choose. I have tried XFCE and GNOME with no problem. More memory will be better, but not absolutely necessary. - As others have said, the wired LAN does not currently work. - Note you can install either to SSD or an external SDHC. The SSD is somewhat faster though. (But you can get larger SDHCs). I am dual booting Linux and FreeBSD on mine right now. Linux is on the SSD and FreeBSD on an 8GB SDHC. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Multiple instances of BIND at startup
Hi everybody, I am attempting to configure a BIND 9 name server that will be authoritative for certain domains which will listen exclusively on IPv6. This same box will also be a caching server for a handful of networks (IPv6 and IPv4). The way I have it set up is that the authoritative and caching services each run a single instance of BIND on it's own IP address, with both instances each doing exactly what they are supposed to do. However, how can I make the FreeBSD (7.0) startup scripts load both instances of BIND, each with it's own configuration? I've read through the Administrators handbook for BIND and numerous newsgroup postings about 'views', but I don't think this is what I want. It seems 'views' are more for split-DNS, segregating internal access and external access to the same service. That is not what I am after. Any pointers much appreciated.

Re: Large filesystems help/ideas
Hi, I'm implementing a backup solution at work.We've bought a x86 server with two hardware raid 5 with for a total storage capacity of about 7Tb. For the software we are using for backups, the ideal scenario would be to have just one big disk so that no space problems would appear. I've tried to install FreeBSD 7 with no success, as it seems... the sysinstall tool doesn't support such big slices. I've read about the Large Data Storage on FreeBSD but I'm still confused. I've also thought on using slices of 1Tb, and join all them using vinum. What do you think about this last option? Thanks a lot for your help. I would suggest to use different partitions for your OS and another big one for your backup data. In fact, if you can use two smaller disks in RAID 1 for the OS and leave your two RAID 5 for the backup data alone, that would be even better. This way you can both a) install the OS without any problem and b) prevent a *very* long fsck in case the machine crashes and your 7TB partition is broken beyond the background fsck process. Once you have the OS installed on the smaller partitions, you can then use gpt(8) to create your 2TB+ filesystems. YMMV. We use a scenario quite identical as what you're trying to do. We use a few ports to do so, like sysutils/rsnapshot and shells/rssh with rsync and OpenSSH along with an encrypted backup volume and OpenPGP to encrypt the tapes. For VMWare images, we use sysutils/rdiff-backup. It works very well for 100+ mixed FreeBSD, RedHat, Ubuntu and AIX hosts. If you need any help with the backup setup and all, just ask, I'll send you the howto.

Jails and multiple ip addresses with FreeBSD 7.0
Hi, I currently have a webserver running Apache 2.2.8 inside of a FreeBSD 7.0 jail. It's running several virtualhosts, and it's doing great! My problem is that I need to run an SSL enabled virtual host, and that requires me to use an IP based virtual host. Most documentation indicates that jails do not support multiple addresses, and I've even found a patch for FreeBSD 6.2. Does a patch currently exist for 7.0, or has this functionality been built in to the new version? Thanks, Mark A.

Probably somebody with loader and filesystem (ufs) knowledge may answer that question quickly if the patch contained in the PR is right. The report is about 6.2-R but at least I've checked loader code and 7.x code is the same. I came across that report yesterday and was unable to check the calculation. If that is really the case, your problem may be related to that. http://www.freebsd.org/cgi/query-pr.cgi?pr=108215 Assuming the problem report is right, it's about reading huge files by loader reads in wrong sectors.

Re: Large filesystems help/ideas
David Robillard escribió: Hi, I'm implementing a backup solution at work.We've bought a x86 server with two hardware raid 5 with for a total storage capacity of about 7Tb. For the software we are using for backups, the ideal scenario would be to have just one big disk so that no space problems would appear. I've tried to install FreeBSD 7 with no success, as it seems... the sysinstall tool doesn't support such big slices. I've read about the Large Data Storage on FreeBSD but I'm still confused. I've also thought on using slices of 1Tb, and join all them using vinum. What do you think about this last option? Thanks a lot for your help. I would suggest to use different partitions for your OS and another big one for your backup data. In fact, if you can use two smaller disks in RAID 1 for the OS and leave your two RAID 5 for the backup data alone, that would be even better. This way you can both a) install the OS without any problem and b) prevent a *very* long fsck in case the machine crashes and your 7TB partition is broken beyond the background fsck process. Once you have the OS installed on the smaller partitions, you can then use gpt(8) to create your 2TB+ filesystems. YMMV. We use a scenario quite identical as what you're trying to do. We use a few ports to do so, like sysutils/rsnapshot and shells/rssh with rsync and OpenSSH along with an encrypted backup volume and OpenPGP to encrypt the tapes. For VMWare images, we use sysutils/rdiff-backup. It works very well for 100+ mixed FreeBSD, RedHat, Ubuntu and AIX hosts. If you need any help with the backup setup and all, just ask, I'll send you the howto.

Re: Multiple instances of BIND at startup
However, how can I make the FreeBSD (7.0) startup scripts load both instances of BIND, each with it's own configuration? I did something very similar. Run one of the bind instances in a jail -- especially with a little firewall rdr rules and similar trickery to redirect traffic into the appropriate instance (which gets you past the lack of IPv6 support in jail(8)). Works beautifully. Thanks Matthew for the response. In all honesty, I want to stay away from jails as much as possible. Once testing is complete, I'll have numerous DNS servers to roll this out to, and I want the least amount of complexity as possible. A few years ago I switched our entire infrastructure from BIND to DJBDNS (with VegaDNS as a web front-end), and now I'm looking to go back. Again, I'd rather do this without jails if possible, and at the same time, be able to use the built in FBSD startup scripts if possible. If not, heres another question: If I need to create my own custom script to do this sort of thing, where should it be loaded from? Some of my firewall rulesets rely on DNS to be up prior to them.

Unusual use of ssh
I have an unusual situation that I suspect is not practical, but just in case... I have a class C network with a T1 to the internet. There are a number of hosts on that network. Unfortunately the T1 line is just part of a path with several additional links before it gets to the upstream ISP. Some of those links are relatively prone to outages. In the same facility, I have a number of WiFi access points that are connected through a router to a DSL connection to the internet. That path is completely independent from the T1 and actually goes through a completely different set of central offices. What I have tried to do is to link the DSL router to one of my hosts via a separate NIC and address that is on the LAN of the WiFi router. So far all is good. I can ping any of the access points from that host just fine. I have established a pass through port in the DSL router for SSH that sends the packets to that host. Sure enough, ssh packets are received by the host. The problem is that it does not respond on the right interface. The routing table uses a default route through the T1. Thats where the sshd responses are being sent. Since I have no a priori knowledge what IPs I would have available when I need to use this back door, I can't pre-setup the routing table. I need sshd to respond on the same interface it receives the packets from. I don't believe that is possible using IPv4 routing. I think that it is using IPv6 but none of the networks involved support that yet. I don't find any option in sshd to force it to respond on the right interface either.

Re: Unusual use of ssh
Sure enough, ssh packets are received by the host. The problem is that it does not respond on the right interface. The routing table uses a default route through the T1. Thats where the sshd responses are being sent. If I understand correctly, this is only one box you need a correction for. Read on. Since I have no a priori knowledge what IPs I would have available when I need to use this back door, I can't pre-setup the routing table. Fair enough. I need sshd to respond on the same interface it receives the packets from. I don't believe that is possible using IPv4 routing. Not at the layer-3 level directly. To do this dynamically you will need to perform some sort of policy based routing. I think that it is using IPv6 but none of the networks involved support that yet. Well, that's a topic up for review. Technically, in IPv6, there is no correlation between how a host selects it's source address for an IP packet based on it's destination address. I've been trying to understand and follow the consequences of this for some time: http://www.ietf.org/internet-drafts/draft-ietf-v6ops-addr-select-ps-06.txt ...or: http://tinyurl.com/64l9pn I don't find any option in sshd to force it to respond on the right interface either. Is there something I have missed? Most likely, if this is a single machine you are speaking of, a script that will check for connectivity to a remote address periodically (eg every five minutes) and then dynamically change it's default gateway at kernel level (not userland level) prior to SSH incoming may fix your problem. This is a little difficult to do without dynamic routing, but relatively simple if you can put up with manually changing back the route once the T1 comes back up. A script that does: - ping remote addr - if fail, route delete default, route add default (ADSL gw) There was a very good discussion on fbsd-net@ last week regarding progress with multiple routing tables. I didn't get right into it so I don't know if it will help, but your true three options are: - dynamic routing (co-operation with ISP's) - IPFW (or equivalent) policy based routing (source routing) - periodic check via a script Regards, Steve ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

The caching name server (service, and eventually cluster) will see tens of thousands of our clients requests (we are an ISP) to use as their DNS lookup, which will perform recursive lookups that we are not authoritative for. I'm sorry, I don't know how to put it into other words, other than I want complete separation from dns authoritative and dns caching services to be disparate.

Let's say your authoritative server is listening on IP-A, and your
caching server is listening on IP-B; both ip-addresses are on the same
host. We can have a named instance listening on both addresses, with
multiple views like:
/*
Used by root .tld.
*/
view authoritative
{
match-destination
{
IP-A;
};
recursion no;
zone my.authoritative.org
{
type master;
...
};
}
/*
Use by our client requests.
*/
view caching
{
match-destination
{
IP-B;
};
recursion yes;
zone my.authoritative.org
{
type master;
...
};
}
The match-destination inspects the DNS address used by the client to
query to determine which view to use. Would this suit your purpose?

I believe that the problem is this: even if configured to be an
authoritative server, BIND will respond to a query about zones
outside what it has authoritative data for with data from its cache
if that data is present. As there is only one cache per instance of
BIND, enabling any sort of recursive capability on a server that is
otherwise meant to be entirely authoritative can lead to data leaking
between the authoritative and recursive parts. This opens up the
possibility of tricking a server into caching false data and responding
with it as if it was authoritative.
In answer to the OPs original question -- yes you can start two instances
of BIND given the obvious requirement that they have distinct network
addresses and ports, pid files etc. You just have to copy the startup
script to a new name and modify the variable prefix internally -- eg. This
chunk at the beginning of the script:
name=named
rcvar=named_enable
you'ld modify to say instead:
name=named1
rcvar=named1_enable
-- modifying all of the other instances of variable name prefixes in the
file from named to named1 similarly. Then you'ld put:
named1_enable=YES
named1_chroot=/var/named1
named1_pidfile=/var/run/named1/pid
etc. etc. into /etc/rc.conf. You can put your modified named1.sh rc script
into /etc/rc.d/ or /usr/local/etc/rc.d/ -- the latter is probably more
desirable as you won't get prompted to delete the file every time you run
mergemaster -- and the rcorder stuff will cause it to be started at much
the same stage in the boot process as the original named.
Cheers,
Matthew
