This means that some monitors allow 'daisy-chaining', and there are also monitor hubs available [1], so there is no 1:1 mapping between ports and monitors.

Re: xfone 018 phone service and Linux
Arie Skliarouk wrote: Hi, Recently I discovered an VoIP phone service by company xfone: http://www.018.co.il/mpa.asp From what I understood, they provide you with hardware phone that is connected to regular internet line (preferably with them as the ISP). They also provide an PC client for windows that supposedly allows you to call landlines and mobiles phones in Israel and over the world using your phone account (similar to skype). They provide you with an adapter that has RJ45 to your LAN/router and RJ11 to your POTS (phone). The adapter does DHCP and then goes out to some SIP gateway. I asked nicely, so they gave me two concurrent outgoing calls (so I can call via Softphone and the adapter). Can someone confirm my understanding? Is the PC client an regular SIP softphone? I am not sure, but you can download it and see for yourself. I did some wireshark captures of it and it does SIP (according to wireshark). The more interesting thing I do is use my Wifi capable E65 to dial using Fring with their account (this also makes my E65 a Skype terminal). I am still unable to make the Symbian SIP client use them. Also, I cannot accept calls via Fring (but I don't care, since I don't give this number to people). They have a 29.90 NIS account for 500min/month (landline only), call price is 0.079NIS/min for landline and 0.32NIS/min to mobile. They are cheaper than regular SkypeOut for calls to Israel. I considered their other option (9.90 for 24 months for the adapter and the rates as above), but didn't want to commit for 24 months. They have a few problems. I cannot dial 1-800 numbers (even their own 1-800-078-078). This is still a pilot. I am still trying to figure what extra services they have (voice mail, voice to email, call forward etc). You cannot move your Bezeq number. They had some billing problem with the mobile taarifs (it was ~3NIS instead 0.32NIS), but I called them and they fixed it. How do they solve the latency problems inherent to any internet connection?

switching eth4 and eth0
Hi guys, This is silly, but at this one I find myself totaly helpless. I have two cards (on a fedora core 8 station), a gigabit, on board and a 10/100. The Gigabit card is mapped to eth2 and the 10/100 is mapped to eth4. One of the libraries uses flexlm for licensing purposes. The license file is keyed on th 10/100 interface's MAC address. Unfortunately, the flexlm likes to use eth0 to verify the mac address. To solve the problem I tried to change the eth4 interface to eth0 without success. Can anyone help me with that?

Re: Cable Internet
And now for some facts about HOT cable service. Cables: When you connect to HOT, you get a cable modem that (usually) has Ethernet connection. When you connect something (router or PC) to that port and issue a DHCP request, you are assigned, as usual, an IP address. The IP address assigned depends on your connection type. Option 1: Your ISP told HOT that your are their customer. HOT DHCP assigns you an address from a pool that belongs to the ISP and routes all your traffic to that ISP. A router for that option need to be able to issue a DHCP request on its WAN link. Option 2: You are an 'open access' client. You get an IP address in the range 172.20.0.0/16-172.29.0.0/16. These addresses can access a restricted set of routers that belong to the ISPs. On top of that connection you can run whatever your ISP chose to do. Some (such as TAU) do PPTP, some do L2TP, but they can also do IPSEC, GRE or whatever they like. This is more flexible because you can switch ISPs without problems. A router for that option need to be able to issue a DHCP request and then run PPTP/L2TP using this IP address. I have seen routers which cannot do that, so you should check your router for that feature (you need to choose PPTP/L2TP and then in the IP address field you need to specify DHCP). So, a router for a HOT cable connection need to have an Ethernet WAN link. I haven't seen routers which have a coax connection and eliminate the need for a cable modem, so compatibility in that respect is not as issue. Enjoy.

Re: vixie-cron acting weird (actually not acting at all)

Yours, Yaron Kahanovitch - Original Message - From: shimi [EMAIL PROTECTED] To: linux-il [EMAIL PROTECTED] Sent: 21:36:53 (GMT+0200) Asia/Jerusalem שבת 21 אפריל 2007 Subject: vixie-cron acting weird (actually not acting at all) Hi All, Sorry for being so verbose, but I was not really sure which of all those details is important to understand the source of the problem :) I've installed a new machine into production on Thursday (19 Apr 2007). Machine is still running since then: $ uptime 21:10:43 up 2 days, 10:11, 2 users, load average: 0.02, 0.04, 0.01 The machine is a Dual Core Xeon 3GHz. with HyperThreading enabled (so grep processor /proc/cpuinfo | wc -l says 4). Machine is running Gentoo Linux, with kernel 2.6.19-gentoo-r5, x86_64. Now for my problem. I installed the system with Vixie-Cron, and crond appears to be running. It appears in the processlist, and it sits in the Ss state on ps. So far - very normal. According to the logs, until April 20th, 19:00, processes ran exactly when they were defined to run (I have a process that runs every 15 minutes). From 19:00 until 23:16:55 (note the 1 minute and 55 seconds after the round hour quarter) - there is a complete silence in the logs. It then resumed running with the same delta from the quarter hour until 00:02am on Apr 21. A bit later, I see that ntpd reports that ntp had no servers available to sync (at 2:31am). Doesn't seem related, but I am mentioning it anyways, as cron is, after all, time based. Occasionally from that time I see Gentoo's run-crons acting at some hours, like 2:50am, 03:07:17am (where is removes the lastrun of cron.daily and 04:26:15am where it ran cron.weekly). At 03:14:25am I also see ntpd synchronized back against 192.43.244.18, stratum 1. There is another run-crons at 05:40am, and weirdly enough, cron kicks back to life at Apr 21, 07:45:41am, with my regular 15-minutes task, which it executes once. Since then, silence until 09:00am where only CERTAIN tasks are executed (and the every-15 minutes DOES NOT), and again silence until 17:16:13 where the every-15 kicks in, then it works at 17:33 and 17:46, and since then, silence again. I tried restarting cron at 20:51:27, the restart got logged. Didn't seem to have any effect. on 21:20:31 I see a run-crons, yet the every-15 does not work. I tried stracing the crond process, and I got the following: Process 6796 attached - interrupt to quit stat(crontabs, {st_mode=S_IFDIR|0750, st_size=120, ...}) = 0 stat(/etc/cron.d, {st_mode=S_IFDIR|0755, st_size=96, ...}) = 0 stat(/etc/crontab, {st_mode=S_IFREG|0644, st_size=1365, ...}) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0 rt_sigaction(SIGCHLD, NULL, {0x40272b, [], SA_RESTORER|SA_RESTART, 0x2b28e1e255c0}, 8) = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 nanosleep({9, 0}, Which I gather should have existed from sleeping pretty quickly, but did not.

So I am thinking there is something maybe wrong with nanosleep(). But what can it be? My guess is related to time drifting due to all those CPUs, but in that case, why did it work great in the begining? I didn't try rebooting the machine, which might have solved the problem (either temporarly or not), but wanted to try and solve it (or at least understand the problem) before I might get it gone.

As a matter of fact, a 10/100 hub is using a dual port switch (aka bridge) to seperate the 100Mb hub from the 10Mb hub. I never used 3com switches but they all have one thing in common - the direct cable connection, some even a telnet connection. There are unmanaged switches. These cannot be configured at all. All you have to do is enterthe interface and configure the switch, I belive that bye seperating the switch into semi-subnets you will solve the problem. for example, lets say its a 16 port switch, just make the first 8 10MBit and the last 8 100MBit, the switch then will use logic to transfer packets between the two subnets. I am not sure I understand what you are trying to describe here. another thing you should do while inside the interface is check the port status, i belive you should see many collisions and packet timeouts which were caused by the missconfiguration of the switch and they are the reason your sessions broke up. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Aviram Jenik Sent: Thursday, June 07, 2001 8:48 AM To: Shaul Karl Cc: linux ILUG Subject: Re: ADSL problems with 10/100 NICs My guess is that those machines are sending packets in 100mbps whereas the Linux machine uses a 10mbps card and loses packets, which results in a broken connection.

I think all modern hubs/switches come with some sort of configuration utility and/or a special configuration port. It could be an RJ45 or a serial port. If you got a CD with the switch, check for a configuration utility that can be installed on a Windows client. If you didn't get a CD, search 3com's (it's a 3com switch, right?) website for a downloadable configuration utility. Also try to connect to it by telnet or through a web browser. Some switches (and hubs, such as the 3Com PS40) are managed switches. Their configuration menus are usually accessible using an RS232 port or Ethernet (TCP/IP) using telnet, web or SNMP. These are more expensive. Some switches (and hubs) are unmanaged. They cannot be configured or monitored. All ports are set to auto negotiation, auto speed. Naturally, these are cheaper.

Re: ADSL problems with 10/100 NICs
On Wed, 6 Jun 2001, Aviram Jenik wrote: I'm having a strange problem with my ADSL connection. I'm not sure the problem is Linux related (probably isn't), but hopefully the solution is Linux related :-) I recently replaced my home network's hub with a dual-speed switch (3Com's officeconnect) that supports both 10 and 100 connections. My home network has a mix of 10 and 100 NICs, where the Linux machine that serves as my ADSL gateway has a 10mb NIC, but 2 Windows machines on the network have 100mb NICs. Since the upgrade, those two machines suffer from strange problems while surfing the web and downloading e-mails, where the connection is sometimes terminated abruptly. My guess is that those machines are sending packets in 100mbps whereas the Linux machine uses a 10mbps card and loses packets, which results in a broken connection. Installing a 10mbps card on one of these stations solved the problem, but obviously that isn't the solution I'm looking for. Is there any way I can configure either the Linux gateway or the Windows machines to solve this problem (MTU settings perhaps?!). Check for duplex settings mismatch. This is the most common problem we had with 3Com switches (and switches in general). Although this usually causes slow tranfer rates rather than broken connections. Do notice that some NICs do not let you set the card's speed and duplex (SGI and some Sun models). In this case disabling duplex auto negotiate and forcing full duplex on the port is a sure way of causing duplex mismatch because these NICs will fall back to half duplex. Also, but this is extremely unlikely, you might have some compatibility problems. I've seen a 3Com LS1100 which had similar problems with Accton NICs of a very specific vintage (November '99 if I am recalling correctly). Also, I have seen some problems with Kingston's hubs. Replace the 100Mb cards with other brands (Intel EtherExpress is always a good choise).

Actually, what you are describing is the BSD 4.n (n=3) behaviour (SunOS 4 is based on BSD4.3). SysV always used swap and RAM to store pages (Irix 3.3 (SysVR3), AIX 3.1 are two SysV OSes that were in use ten years ago and used the 'new' model). In BSD 4.4 (which FreeBSD 2.x and above is based on) this is no longer true. also, RAM was very expensive back then, so it was scarce. these days, however, RAM is cheap, and linux does not do that pre-allocation (and i think neither do other modern unices), so some people manage to run their machine without using any RAM at all. if you system starts using swap space alot - it's often cheap enough to simply buy more ram. using a lot of swap is mostly leftrelevant for heavy-duty machi, and even then you try to get your system to do as little swap as possible (especially if you're running an interactive web server, or similar). You ment '... run their machine without using any swap at all.'. That's true. It is unlikely that if your machine has 0.5Gb of RAM you will install 1Gb of swap. Just try to imagine (calculate) what will happen if you start swapping 1Gb. This discussion usually comes hand in hand with the swap file vs. swap partition discussion. I always felt that during the installation you should install lots of swap space (~250Mb, or even more), just to be on the safe side (with today's disks it doesn't make sense to save here). If you go out of swap, add a swap file (don't re-partirion). Once you start swapping, it is going to crawl anyway and it doesn't really matter which of them you use. The obvious answer is to buy more memory. thus - allocate RAM based on your experience with the pattern of usage of your machine. You ment allocate swap.

IMO, its strong YZ points (compared to Linux) are: I'm a bit surprised how many myphologized is a mind of an average advocate. What you say is "standard 'Linux sucks' advocate kit". As most "standart advocate kits", it's built on myths that or were true 5 years ago, or were always false. I didn't say that Linux sucks. I said that FreeBSD has some stronger points. YZ. It is based on sources from a single source (UCB CSRG), while Linux is YZ derived from many non complaint sources. Well, ITYM "non-compliant". In fact, just yesterday I've read an article that says BSD is better because in Linux you have just Alan and Linus in full control of code, while in BSD it's full team. You are confusing an OS and a kernel. These are not the same. An OS has a kernel and a few more supporting programs. YZ. The develpment cycle is slower. A stable major release every three to This is an advantage, yeah? So now development at all means a perfect system? Slower means added stability. Rabid upgrades make systems less stable. I am not suggesting that Linux cannot be stabalized in that respect. It just seems that people are upgrading "becuase they can". YZ. The development cycle is centralized. Authorized developers are making YZ changes to a central cvs repository. You'll be surprised, but there's some little guy named Linus Torvalds, who has a little kernel tree that is akinda official. Isn't this a thing you call "centralized"? Again. OS vs. kernel. Linus maintains the kernel tree, not the OS tree. YZ. The development cycle contains all major OS parts. This means that when YZ you say FreeBSD 3.2, you are refering not only to a kernel, but also to YZ libc and most system binaries (such as ln, awk, grep etc). I know yet another system which has almost all system binaries intergated into the OS. I do not like that OS. Developing an OS and developing awk is different things. Side note: I could guess what you meant, but you said totally different thing... Let me iterate. Developing kernel and other OS parts, such as libc, other libraries and /usr/bin in the same cvs tree makes the system more integrated. There is less chance that changes to libc will break calls in grep, because after you make your changes, you compile everything together. YZ. Its UFS is more stable than ext2fs which optimizes like hell. See SGI's YZ initiative of donating XFS sources to Linux. Which one does optimize? ext2fs optimizes to a dangerous level. And why donating XFS means UFS is better than ext2? I think I've lost your point here. SGI, being a Linux advocate and a company that wants to ship Linux on a commercial basis for their systems wanted a file system that delivers, so they offered a better one. YZSummary: my choise for a stable, fast, conservative network server. Did you try a marketing job in a big corporation? Nope. I do sysadmin for a living. P.S. Could we bury this holy war now? Actually, I had no intention of starting a flame war (althogh i suspect it might end as such). There were no personal insults in my mail. If you want to promote BSD, get beyond pack of myths and *promote* it, not demote Linux. Saying "X is worse" is not the same as saying "Y is better". Think positive.

This seems to be an argument flogged about greatly, but it REALLY depends on what you mean by ``better''. Performance wise, I don't know.It's hard to do good benchmarks and I haven't performed any.Plus, results change all the time. These days, you are probably right. Performance-wise, Linux has probably improved a lot. Cutting edge wise?I'd say that Linux appears to adopt changes faster than BSD does.But what does this really say? For example, in traditional BSD stacks, every TCP timing activity (RTO, delayed acking, etc) are based on heartbeat timers and are therefore coarse grained.Just a few days ago, FreeBSD commited changes to their tree thatreplaced these timers with callout wheel based timers, increasing the TCP timer granularity.Linux, IIRC, has had fine-grained timers forever.On the other hand, it's not exceptionally clear how big a win this is.In fact, some research indicates that fine granularity clocks may not be so great. Linux is indeed known for faster adoption of technologies. I think the appropriate line is that BSD code is more stable than the Linux networking code.It is definitely more mature. I suppose we can agree on that one as well.

On Mon, 12 Jul 1999, Omer wrote: Small comment: The x2 rule doesn't actually mean anything now, as far as I know this rule-of-thumb comes from unices which will not use RAM unless they have swap to shadow it with. That is correct. The "swap should be twice the RAM" rule holds true for BSD prior to version 4.4 (4.3 and below). It is not true for BSD 4.4 and SysV, as well as Linux. You can use this rule if you don't have any idea what will be your total process size. Of course, in this case, with 32MB of RAM he could use 128MB of swap. The system shouldn't be paging that much with 32Mb RAM. This configuration sounds very reasonable for X and netscape. As usuall, adding more RAM will improve performance. Adding more swap will not improve performance, it will just let you run your applications. I would guess that your netscape is indeed running out of swap, so it would be a good idea to add some. Assuming you are not into re-partition and install and no extra disk is laying around unused, I would advise that you will do this using a swap file (rather than a swap partition). Purists might argue that this will be slower, but it will do the job. Take a look at mkswap(8) and swapon(8) for more details, but basiclly you should do the following: dd if=/dev/zero of=/var/extraswap count=100 bs=1024k mkswap /var/extraswap swapon /var/extraswap This will give you 100Mb of swap (assuming you have a spare 100Mb on /var). Don't forget to add this to your /etc/fstab so that it will be added after each boot. -- Yaron. = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
Fast Ethernet PCMCIA card for Linux.
Hello all, I am looking for a FE PCMCIA card for Linux (supported under RH6.0). I need something that is being sold here in Israel. It need to be able to perform good (~50Mbps). The card should go into Compaq Armada 4150 (or a Dell Latitude if this would make a difference). I have spoke with the following: 1. Binat, which sell Silicom. Silicom are not supporting Linux anymore (they used to for their 10baseX cards). 2. Sisconet (?) only do 3Com (which is said to have performance problems). 3. Taga carries Xircom (I have one on loan on my desk and will hopefully test it later this evening :-(). Their first Kingstons will only get here next week. 4. Linksys (US) has no Israeli distributor. Looking at the supported cards I found the following: [3c574_cs driver: has performance problems] 3Com 3c574TX, 3CCFE574BT [3c575_cb driver: experimental!] 3Com 3c575TX, 3CCFE575BT, 3CXFE575BT CardBus Intel EtherExpress PRO/100 [ 16-bit, NOT 32-bit ] The rest of the gang are cards which I never heard of and don't know anything about. Does anyone have a working FE card they can recommend ?
