Re: [expert] Network card causes modem to disappear
Trying to think logically about this so that I can generate a model of what is going on. If I can use the modem with no network card in the box, then that seems a good test that at some level everything is OK. But if the modem goes away when I add the network card, then that seems to indicate that the presence of the network card somehow conflicts with the modem. What else do I know? Well, I know that the modem card is on IRQ 10 regardless of whether the network card is present. I also know that the network card is on IRQ 5. So I'm wondering, is there any way to get a device-by-device listing of what's occupying the various IRQs? (One hypothesis being that something else was sitting on IRQ 5 and moved to IRQ 10 when the network card appeared and occupied IRQ 5. I know that the PCI bus is not supposed to allow two devices to occupy the same IRQ, but I'm grasping at straws.) FWIW I have the following line in /etc/rc.d/rc.local: setserial /dev/ttyS4 port 0xec00 uart 16550A irq 10 ^fourport Does this look reasonable? If I use auto-irq instead of setting it explicitly to IRQ 10, setserial does report that 10 is reported back by the port, so explicitly setting it to 10 looks like it should be OK, although I suppose I could always experiment and do an auto-irq probe at boot time. You'll notice that I'm still not prepared (yet) to believe that this is a WinModem; I just can't fathom how it could ever have worked if it were a WinModem. And of course, the manufacturer says I have to go to Micron for support, and Micron says it supports only the OS that was on it the time at which the box was sold. They do confirm that this is not a WinModem -- if we believe them (actually, though, I've found Micron support to be very good in the past, that's the principal reason I bought from them again this time).

Do this...go look and make SURE you don't have to add any extra software for it to work under Windows. Have you tried dialing out from a plain, F8 boot? (i.e. at the boot prompt, hit your F8 key to NOT load *any* drivers.) I'm not sure how you'd do this with LILO. Maybe just have a generic Dos / Windows boot floppy with command.com on it and boot off that? Anyway, once you've gotten to a no-drivers-loaded boot, type "echo atdt[some-phone] >comX" (where X=com port of your alleged modem.) AFAIK, there is ALMOST no such thing as a PCI modem which is NOT a WinModem.

I specifically changed the order from the default (which is, of course, a Win-pseudo-modem) and they charged me for a real modem; the documentation (such as it is) also looks like it belongs to a real USRobotics/3COM modem. As I understand it, the modem gets configured to IRQ 10 during power-on by the PCI gubbins, so there's no way to control that. And it really does work perfectly without the network card in there; my understanding is that a WinModem wouldn't be accessible at all, since there wouldn't be a driver for it anywhere in the system.

[expert] Network card causes modem to disappear
I've tried to post this several times already over the course of the past few days, but I have seen nothing appear on the reflector. Haven't received any bounce messages either, so I don't know where the messages think they've been going. Anyway, apologies if you've seen this before. - A nasty problem 1. Running Mandrake 7.0 without any fancy modifications on a 733 MHz Micron box. 2. I can access the modem just fine (e.g. for PPP, etc.) The modem is on ttyS4 (COM5). [ Don't ask me, that's the way it came in WinDo$e, so I put it on ttyS4 for Linux. ] I have /dev/modem soft linked to /dev/ttyS4. 3. I add a Linksys Ether PCI II card (no other NICs in the box). 4. Suddenly I can no longer access the modem. At all. In any program. kppp, for example, says "searching for modem" and then "modem is busy". Even statserial doesn't work (complains about TIOCMGET not being supported, although of course it works fine when the network card is not in the box). 5. If I take the card out, I can access the modem again. 6. Even if I tell Kudzu not to configure the network card at boot time (i.e. the third option of the three that are presented), I STILL can't get to the modem if the network card is phsically inserted in a slot. 7. The really bad news is that everything works fine under WinDo$e. Actually, I suppose that's not really so bad, because it at least indicates that there's no fundamental hardware problem. So, any ideas as to how I might be able to have a network and a modem at the same time would be most welcome. Or even how to diagnose the problem. Oh, some extra info: The modem is on IRQ 10, and the network card is on IRQ5. The I/O addresses are also nicely different. And the network card appears to work OK (although I haven't "torture-tested" it, having been too busy trying to figure out why I don't have a modem any more). I have a separate serial port on COM1 (on the motherboard). It works fine regardless of whether the network card is in place. Doc Evans -- D.R.

Re: [expert] Network
Snifit might be a problem though, I know from personal experience that packet sniffers might be frowned upon on by your school's network administrator. You could try ippl which should be on linuxberg somewhere, probably freshmeat as well or try iplog which should also be on freshmeat. After that, you might try creating a start up script for it. It was actually alot easier than I though it would be, take one of the previous start up scripts in /etc/rc.d/init.d/, create a new one and copy one of the old ones. Then just replace the old program witrh the new one that you're starting up.

[expert] Network and Threaded Programming on Linux
I would like to do a fairly advanced side project that involves heavy use of threads and UDP socket programming. Since I haven't done this in a while, I would like to find some good books that would cover these issues well. So, can anyone recommend a definitive guide to network/socket (UDP), multithreaded coding with C++ on Linux? Something fairly recent would be nice, but if an older book does the trick, that's fine too.

Re: [expert] network question
i think with netconf or linuxconf you can also name your host and your domainname. if not maybe you can set it in /etc/sysconfig/network and/or /etc/Hostname /etc/Domainname.

Edit your HOSTNAME file, or run LinuxConf and select your "network" setup and change it there. I'm *guessing* the problem is that your system is saying "Hi, I'm 'localhost.localdomain'" and your gateway is saying "Heck, I don't know anyone by that name. Go away!"

[expert] Network printing question.
I have recently upgraded my workstation to Mandrake 7.0 via a clean
wipe-install. I also have a Win98 box, a spare linux workstation and
a linux samba server, both running Mandrake 6.1, on my home network.
The 7.0 box has samba v2.0.6 while the other two have 2.0.5a.
The previous version of linux was red hat 6.0 and it printed great to
the Panasonic KX-P4450i laser printer I had on my server. This was a breeze
to setup with samba and printtool. Well, now with the new version of linux
on my workstation it won't print. The spare linux machine and the Win98 box
still have no problems printing to the laser printer. All other samba
functions work fine and when I boot to Win95 on my workstation, windows prints
fine. I am again trying to setup the printer with Printtool. The spare also
has a local printer (HP 500 clone) hooked up to it. My workstation cannot
print to either printer.
All this makes me think I have done something stupid with the samba setup on
my workstation.
Any ideas?

Re: [expert] Network Question:
Well the problem that you are having with the envizex terminal is not surprising. In order to get it to work you need the code for the xterminal either on a floppy disk or loaded on the linux box. Since the Xterminal is an HP and the software is propriatery software (Netstation 9 or 7.1) I doubt you will get it to work. But if you do have the code loaded.

Wouldn't it be much less expensive to put a modem on your workplace PC, and configure it (the workplace PC) as a router/firewall for your home PC ???

Well, it's possible to connect system 2 to system 1 (will need some modem line on system 1, or its network, too...) but obviously you _cannot_ benefit fully of the T1 speed, because everything will be limited by your modem line's speed ... Now if your aim is only to avoid the ISP charging you for the modem connection, that's okay ... and if by chance you have a toll free number to your workplace, you may even avoid the phone line charge ... -- Jean-Louis Debert[EMAIL PROTECTED] 74 Annemasse France old Linux fan

So system 2 > > can benifuit from the work T1 Line. You can do a mini-ISP thing. Get a Web Ramp. The model with external modems is fine, like the 300e or 310e. use a single modem. Your home computer then dials into the webramp via its regular modem/phone line. The webramp answers and puts you on the ethernet at the office. How you go from there is up to you. http://www.rampnet.com Its a small box, size of a paperback or cigar box. It has 3 serial ports for up to three modems. Other end has a small ethernet hub. It is a complete dial in/dial out and IP Masquerade solution in a small box with no moving parts. About $300, far cheaper than a computer. From the ethernet side it is managed via a built-in web server interface. Out of the box it is 192.168.1.1, but that can be changed easily. There are several models; be sure you get one that allows dial-in. You can do the same thing with an older 486 or Pentium box running IPMasquerade, Coyote Linux, Linux Router Project or FreeSCO (Linux based) or IPRoute (MSDOS based). Of those, it seems Coyote has its act put together the best. I am playing with one here right now. Coyote does ether-ether and does not do PPP, but the others all do ether-ether, ether-PPP or PPP-PPP. In my experience, using a dedicated box like the WebRamp is a better solution if it fits your requirements. Cisco, Bay, Ascend and others make similar equipment. -- Ramon Gandia = Sysadmin == Nook Net http://www.nook.net[EMAIL PROTECTED] 285 West First Avenue tel. 907-443-7575 P.O.

Re: [expert] Network goes away after some idle time
I too had this problem with a static IP and cable-modem setup. Civileme and Axalon helped me through my gripes and confusion, and yet it took me almost two weeks and talking on the phone with not one, not two, not three, but four tec-support individuals to track down the problem and it was one who runs L-M 6.1 at home that actually came up with the proper diagnosis and solution. First be patient with your tech people. Have your MAC address handy. If you need to check , try 'ifconfig' (as root or su) and its the 'HWaddr xx:xx:xx:xx:xx:xx' (numbers and letters of course) on you gateway card. Then ask them to check and see if they have "tacked" a 'NetBios filter' on your assigned IP address and to please remove it. Don't rant about the inadequacies of M$ and the "prowess" of Linux. That just gets them defensive. If necessary, (if you dont already have it), ask for a staic IP (usually about 10$ extra) at least With my ISP. Anyhow good-luck and I second or third Civileme's motion to discover, design or invent a Linux method to by-pass this kind of filtering agent. William Bouterse Juneau Alaska

RE: [expert] Network goes away after some idle time
It is not my ISP simply because when I boot under NT the problem goes away. Also the traceroute stops at my machine when it doesn't work. Again the funny thing is the network comes back alive after some times (between 10 min and 40 min). I also tried several NIC (3com and Reltek ) and the problem is persistant. I also tried Mand. 6.1 and 7.0 and the problem is still there. --- Lyle <[EMAIL PROTECTED]> wrote: > What kind of NIC's are we talking about?

RE: [expert] Network goes away after some idle time
What kind of NIC's are we talking about? And how do we know that it's not your ISP that's blocking the pings? Where do the traceroute's end? A traceroute when it works and when it fails would be usefull here. Also my ISP changed routers last summer and they now block all pings & traceroutes from the outside world. It's also possible that your ISP has timeouts against keeping track a route to your linux gateway and that sending a ping is just refreshing their router tables.

I have a Dell Inspiron 7000... I just installed the new Mandrake Air, everything works great cept the networking. I have a 3com 10/100 card (no modem) I think its a 3c575. When I installed the system ISMOD crashed when detecting the card so I skipped the network installation. It DID give the correct info about the card on a screen for about 1.5 seconds before it crashed. I manually set up the card with netconf.. I put in the ip/dns/routes.. I selected a mask of 255.255.0.0 and selected interface eth0.. I put nothing in for the kernel module or irq, i/o ports.. I started pcmcia and networking.. Running ifconfig eth0 gives me the correct info.. It gives me the ip addy I gave it as well as the nics hardware addresss... I can ping localhost AND the ip I gave the card (same ip that works with windows) That is as far as I get though.. nslookup fails cuz it cannot find the servers.. I can't ping any other machine Any ideas??? Dell seems to have released a 3c575.rpm but its for RedHat... go figure... Thanks, Bob

[expert] Network goes away after some idle time
I have the following problem on my linux gateway machine (at my home). The machine has two NIC cards. Eth0 is DHCP via adsl. Eth1 has static ip for my internal network. IP_MASQ is on to forward packets from my internal network. Everything works nicely, except that if I went to work and tried to ping my home (gateway) machine I notice that the ping the machine does not "always" respond. I tried to track this and found out that eth0 seems to "fall a sleep" once in a while. However, my internal network has never had any problem getting out. All I can say is that once eth0 falls a sleep I would have to try later and it will somehow wake up by itself (no reboot or anything is required to get to work again, just waiting about 10-30 minutes). APM is turned off on the BIOS and the OS. The only way I was able to remedy this is to have the gateway machine ping an external site (www.yahoo.com) every 1 minute. With the ping on, I can alawys get to my gateway machine from work. I have few peopel on the web that have the same problem and none could figure out what the story is. Any help is highly appreciated. Thansk __ Do You Yahoo!? Talk to your friends online with Yahoo! Messenger. http://im.yahoo.com

A reboot brings; Now 'nslookup' for 'anyplace' gives "can't find server name for address xxx.xx.xx.xx no response from server" and 'network is unreachable' message if I run a check such as ifup eth0 . I can ping internal IP to server but thats it. Did Linux/Drak Conf mess with settings as I have heard rumored? Is it necessary to disable linuxconf and/or DrakConf at bootup to maintain config-settings integrity.? I have run through the basic settings and conf files to check any unknown changes. Dang-it this was working fine before rebooting!!!

RE: [expert] Network Problems.
Give the linux machine two IP's on one interface. One on each block. Then put a static route as default route to the firewall (Which should be there already). Now you have a linux machine that can talk to both networks and the internet. You need to turn on routing on it too. Next just make the linux machine your default gateway in the machines that you need to access both networks. Depending on the network block you are in you need to set as default gateway the ip on the same block. BTW you can do the same with an NT machine =). But I think you have to be running NT server for that (not sure).

Re: [expert] Network Problems.
While not fully understanding you question.. If your wondering why you cannot see the different subnets via the network neighborhood or smbclient then this is your answer. The netbios that your windows machines use cannot cross subnets without the help of a router. To fix this Micro$oft created something known as a master browser. If you set your linux box with samba to be the master browser and you point all of your windows machines to it you will be able to see machines across a network. You must tell your windows machines what the master browser is. This is done via the WINS PRIMARY SERVER box found somewhere in the networking. This master browser is just a server that keeps track of where "network neighborhood" machines are located. You can adjust the priority of you samba box to become the master browser for the whole network... BTW Since you say you can get to your POP server and the internet.. I'd say it has nothing to do with your gateway settings. .02 Bob >At 01:39 PM 12/16/99 -0600, Sean Armstrong wrote: > >>Ok. I am not sure if this is off topic or not so >>bare with me.

Re: [expert] Network Problems.
under Windows NT, you have the ability (under the "advanced" button in tcp/ip settings) to have multiple ip addresses or networks on your machine. also, under linux, using ip alias, you can have multiple ip addresses or networks on your machine. linuxconf may set that up for you. bug On Thu, 16 Dec 1999, Sean Armstrong wrote: > Ok.

More likely, you did not set up your mandrake box with the right gateway address in your subnet. e.g. if the two blocks are 192.168.1.0/255.255.255.0 and 192.168.2.0/255.255.255.0, there must be a corporate router that each subnet can talk to (with an address in each of those subnets). So, for example, if your subnet is the 192.168.2.0 subnet, and they tell you the gateway for that subnet is 192.168.2.1, then you put that in the default gateway entry for you mandrake box, and you will be able to see all addresses in the the 192.168.1.0 block as well (since they are not local to your subnet, linux will automatically forward packets for them to the router...)

Ok. I am not sure if this is off topic or not so bare with me. My work network is a NT network and most of the computers are Win98 or NT. As a matter of fact only three are others(2 linux boxes and 1 Mac). Our network has two different sets of IP blocks for use. Since they are different if I use an IP from the block that is not part of the main IP adresses I can not see my computer from another win computer. I can not communicate with the other block of IPs. I can still connect to the mail server and the internet. I think the firewall the company has up may be blocking access between the two blocks of IP addresses since SAMB uses TCP/IP to communicate to the network. The network servers are on the main block of IPs and I don't want to have to go back to DHCP because that's just as useless. Any ideas on how to get around this problem?

[expert] Network card un-initialization
Hello, I've been tackling a project I've been wanting to get started for a long time, a Linux ipchains firewall. I seem to be having connectivity loss if I leave the machine alone for a long time. The firewall looses it's internet connection. Here is some background info: Mandrake Helios (6.1) 3c509 NIC eth0=outside(cable modem DHCP via RoadRunner) 3c509 NIC eth1=inside(192.168.0.1) 2 client (internal) pc's IPCHAINS with portforwarding via ipmasqadm The connection works GREAT for quite a while, so, my first thoughts are related to the external DHCP (I don't know how long the lease is for). In my messages file, it appears that I successfully get a new lease, but I see where the DHCP client seems to be re-initializing the network cards, IS THIS NORMAL? Also, when I return from my absence, I can alway tell that I've lost my connection because my active TTY has these errors on the screen: eth0: Setting Rx mode to 0 addresses. eth0: Setting Rx mode to 1 addresses. I'm betting that this is a hint. I can't, however figure out how to get the NIC to work again, it still has an IP (in ifconfig), and it appears to still have a route table (in route), but it can't ping anything outside of this interface. Even doing an (ifdown eth0) (ifup eth0) doesn't help. And remember, my other network card still is operable on my internal network (eth1). Anyone have any ideas?

[expert] network card wont load automatically ?
I am running Mandrake 6.0-1. I have a AT-2450 network card. All worked fine until I changed the card to a 3C905B. I could not make that card work, so I put back in the AT-2450. Now when I boot the card fails. I have to manually load the module, then run netcfg to activate it. I did a modprobe -c and there are line to load the card drivers, then lower in the list is a line alias eth0 off. Where does this line come from ?? How can I get this thing back to normal ?? Brian D.

Re: [expert] network problems on Mandrake 6
Herman, It seems odd that your not even seeing a light on the eth0 to show that it is connected. That seems to be your main problem. You might want to check when your using RedHat 5.1 what IRQ and IO address the cards are using. My dual 3C905b's share IRQ 9. If 5.1 is setting it different you might want to put the settings in your conf.modules on Mandrake. Also are you using DHCP on eth0 or setting it static? Are you trying to set it up so that your local net goes through eth0? If so. Couple things I would check is to make sure you have routing turned on. You can get to it through linuxconf under "Networks/Routing and gateways/set defaults" Make sure "Enable Routing" is checked.

It's OK - here you go: (I'll leave my machine open for a while;-))cards are (both) 3c905B-Tx Kernel=2.2.9-19mdk Ping to 209.115.168.27 is OK, but I've been told that a ping of the own IP address doesn't even touch the card??? 209.115.168.25 is as dead as can be (and everything else I should be able to reach on our little 209.115.168.xx sub-network) I can ping the internal network 192.168.42.xx And as I told before: the whole configuration works with an older RedHat 5.1 - Linux 2.0.35 (I tell you this *ONLY* for the sake of confirming that the hardware runs perfectly - I do want to change to the newer kernel - and Mandrake - I liked very much what I saw until now) Thanks, Herman

Re: [expert] network problems on Mandrake 6
Herman, I have the exact same network card combo here. (two 3c905b's). I have the same information in /etc/conf.modules also. Mine works fine. One NIC (eth0) goes to my Cable modem and the second NIC (eth1) goes to my hub for my local network. What output does ifconfig give for eth0 and eth1? What are you trying to ping?

Hi, After installing Linux Mandrake 6.0 I do have a problem with my network: Motherboard GA-6BXC (Gigabyte) Two network cards 3com - 3C905B-TX (PCI cards) I use the default installed driver : 3c59x (conf.modules = alias eth0 3c59x alias eth1 3c59x) The whole hardware is OK, since I installed RedHat 5.1 on the same machine, same configuration and it just works fine. Only installing Mandrake just does not get my network connections up and running! ifconfig gives me both cards, but ping doesn't give any response Is there something I missed? Is this a known issue? Thanks for any advice. Herman

[expert] Network woes...
Hello all, Sorry in advance for the long, drawn out message. I am setting up a ip-masq box (Mandrake 6.0) with two ethernet cards. The one connected to the ADSL modem is fine (eth1). However, I can't get eth0 to talk to my local network. Call the masquerade box A and the (local) client B. I know that the local network for B is OK, as I can ping another client box C. Here is the routing table for A (with eth1 down) Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 127.0.0.0 * 255.0.0.0 U 0 0 0 lo Here is ifconfig eth0: eth0 Link encap:Ethernet HWaddr 00:A0:24:1A:D2:1A inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:604 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 Interrupt:3 Base address:0x300 Here is the ifcfg-eth0 file: DEVICE="eth0" IPADDR="192.168.1.1" NETWORK="192.168.1.0" NETMASK="255.255.255.0" ONBOOT="yes" BOOTPROTO="none" When I ping B from A this is part of the result of tcpdump -i eth0 on B: 11:33:41.282743 arp who-has B tell A 11:33:41.282814 arp reply B is-at 0:60:97:74:bc:14 However, I am getting no response on A.. So it appears to be a routing problem, but I cannot for the life of me get eth0 on A to respond. BTW, the light on the hub is on for the connection to eth0 on A . I am at wit's end and would ever so appreciate someone pointing out what I am missing. I have successfully set up ip-masq fine before, but am stuck on this one.

[expert] Network unreachable
I've got a very strange problem with an 3com 905B Ethernet card (Boomrang) : The network connections starts to work fine, but stop after a while. (a ping or a route tells me that the "Network is unreachable" !) Then, in order to make the network connection work again, I have to reboot the machine, which launch again the network services... The network connection is completly stoped : a ping from another machine don't reach my linux box ! Please help me ! Pleeeaase ! I'm getting mad...
