[expert] Network problems
Hi all, I've run into a couple of problems the *fm's I can find don't solve. How in 'ell do you UN configure the Internet connection sharing #1: While trying to set up Internet connection sharing I fsck'd my local network e.g. NO NFS connection.. OK referring to a suggestion sent on this subject several weeks ago, I tried to then set up static IP addressing, Nope, no worky.. I don't get NFS OR connection sharing. Worse yet, now I can't even ping the nameserver of my IP, Dial Up Connection (216.190.159.2), so no Internet or email. I can ping my other computer(using local term window), the one I set as the dhcp server, leaving the IP address static on it. I'm using it to send this mail so it seems to be working OK as far as Internet connectivity is concerned. #2 I though to my self, OK, if need be I'll set up SAMBA and use KOMBA2 to browse with. Well, Komba sees the share but as soon as it opens the file browser it closes it right back down. This doesn't happen browsing a Corel Linux system I have set up as a file server, Komba works OK. So as it stands right now, I don't have either Internet connection sharing or ANY kind of network that I can use. My goal: 1: Intenert connection sharing over a 5 computer network(IP range from 192.168.0.1 up, originally set up static on 192.168.10.x up). 2: NFS networking between all of the 5 computers (all running MDK 8.1 except the Corel1.2 file server) The system I want as a gateway machine is an Athalon 1.2Ghz, 512Mb RAM and a good 56K/bps modem. NIC is LinkSys 10/100 PCI, no problem with it. I have a 3Com 10/100 12 port hub and a LinkSys switch being used as a hub to extend the distance of my short cables. Overall length is under 50 feet. So, in total I need help figuring out how undo whatever the Wizard did OR get it configured right so I will have a usable network again.

On the gateway machine, the one attached to the internet, is the router? Whatever address this network card, the one that is connected to the hub will be the gateway for all the other computers. So on the other computers simple point then to this address as the gateway. Say the address of the router is 192.1268.1.1, then this is the address of the gateway that they would point to. Also on the computer use as the router gateway insure that /etc/sysconfig/network has NETWORKING=yes and FORWARD_IP4=true. You may wish to add the other computers address and names in the /etc/hosts file. As for Komba2 you might try adding under the setting configure the range of ip's to scan. You may need to set the passwords up first. Also try pinging from and to each machine. Larry -- Sword'sEdge VoiceMail/Fax: (858) 860-6406 x1587 Want to buy your Pack or Services from MandrakeSoft?

[expert] network problems with kernel 2.4.16
Hi everybody, After succesfully installing Mandrake 8.1 on my PII 333MHz, and checking everything was running allright (network included), I decided to download kernel 2.4.16 sources for compiling it on my own. Compilation and installation session run without apparent problems. It was on booting sessions when I came across network failed. In particular, it seems that although network interface eth0 is brought up succesfully, this cannot be assigned to the IP address specified by me. I'm attaching the corresponding tail of /var/log/messages file (some of lines are in Spanish, but the ones concerning network failure are in English): Dec 4 09:14:06 gaback date: dt dec 4 09:14:06 CET 2001 Dec 4 09:14:06 gaback rc.sysinit: Setting clock (localtime): dt dec 4 09:14:06 CET 2001 succeeded Dec 4 09:14:06 gaback rc.sysinit: Loading default keymap succeeded Dec 4 09:14:06 gaback rc.sysinit: Activando partición de intercambio: succeeded Dec 4 09:14:06 gaback rc.sysinit: Setting hostname gaback.ges.ub.es: succeeded Dec 4 09:14:06 gaback fsck: /dev/hda6: clean, 87611/480960 files, 317508/961884 blocks Dec 4 09:14:07 gaback rc.sysinit: Remontando sistema de archivos raíz en modo de lectura y escritura: succeeded dec 4 09:14:07 gaback rc.sysinit: Encontrando dependencias de los módulos: succeeded dec 4 09:14:08 gaback rc.sysinit: Montando los sistemas de archivos locales: succeeded dec 4 09:14:08 gaback rc.sysinit: Montando sistema de archivos loopback: succeeded Dec 4 09:14:08 gaback devfsd[85]: read config file: /etc/devfsd.conf dec 4 09:14:08 gaback rc.sysinit: Running devfsd actions: succeeded Dec 4 09:14:09 gaback loadkeys: Loading /usr/lib/kbd/keymaps/i386/qwerty/es-latin1.kmap.gz dec 4 09:14:09 gaback keytable: Loading keymap: es-latin1 succeeded Dec 4 09:14:09 gaback loadkeys: Loading /usr/lib/kbd/keymaps/include/compose.latin9.inc.gz dec 4 09:14:09 gaback keytable: Loading compose keys: compose.latin9.inc succeeded dec 4 09:14:10 gaback keytable: succeeded dec 4 09:14:12 gaback rc.sysinit: Habilitando espacio de intercambio: succeeded dec 4 09:14:14 gaback mandrake_everytime: Building Window Manager Sessions succeeded Dec 4 09:14:14 gaback modprobe: modprobe: Can't locate module eth1 Dec 4 09:14:14 gaback modprobe: modprobe: Can't locate module eth2 Dec 4 09:14:14 gaback modprobe: modprobe: Can't locate module eth3 Dec 4 09:14:14 gaback modprobe: modprobe: Can't locate module eth4 Dec 4 09:14:14 gaback modprobe: modprobe: Can't locate module eth5 Dec 4 09:14:14 gaback modprobe: modprobe: Can't locate module eth6 Dec 4 09:14:14 gaback modprobe: modprobe: Can't locate module eth7 Dec 4 09:14:14 gaback modprobe: modprobe: Can't locate module eth8 Dec 4 09:14:14 gaback modprobe: modprobe: Can't locate module eth9 Dec 4 09:14:14 gaback devfsd[85]: error calling: unlink in GLOBAL Dec 4 09:14:15 gaback init: Entering runlevel: 3 Dec 4 09:14:15 gaback devfsd[85]: error calling: unlink in GLOBAL 27Dec 4 09:14:15 devfsd[85]: error calling: unlink in GLOBAL dec 4 09:14:15 gaback usb: Loading USB interface0 (usb-uhci) succeeded dec 4 09:14:16 gaback network: Configurando parámetros de red: succeeded dec 4 09:14:16 gaback ifup: Cannot send dump request: Connection refused dec 4 09:14:16 gaback network: Activando la interfaz lo: succeeded dec 4 09:14:17 gaback ifup: Cannot send dump request: Connection refused dec 4 09:14:19 gaback ifup: Cannot send dump request: Connection refused dec 4 09:14:19 gaback ifup: Error adding address 161.116.228.150 for eth0. dec 4 09:14:19 gaback ifup: Cannot send dump request: Connection refused dec 4 09:14:19 gaback ifup: bind: Cannot assign requested address dec 4 09:14:19 gaback ifup: Cannot send dump request: Connection refused dec 4 09:14:19 gaback ifup: Cannot talk to rtnetlink: Connection refused dec 4 09:14:19 gaback network: Bringing up interface eth0: succeeded dec 4 09:14:20 gaback internet: Checking internet connections to start at boot succeeded Dec 4 09:14:23 gaback xinetd[857]: Service ftp: attribute already set: disable [line=16] Dec 4 09:14:23 gaback xinetd[857]: chargen disabled, removing Dec 4 09:14:23 gaback xinetd[857]: chargen-udp disabled, removing Dec 4 09:14:23 gaback xinetd[857]: printer disabled, removing Dec 4 09:14:23 gaback xinetd[857]: cvspserver disabled, removing Dec 4 09:14:23 gaback xinetd[857]: daytime disabled, removing Dec 4 09:14:23 gaback xinetd[857]: daytime-udp disabled, removing Dec 4 09:14:23 gaback xinetd[857]: echo disabled, removing Dec 4 09:14:23 gaback xinetd[857]: echo-udp disabled, removing Dec 4 09:14:23 gaback xinetd[857]: linuxconf disabled, removing Dec 4 09:14:23 gaback xinetd[857]: ftp disabled, removing Dec 4 09:14:23 gaback xinetd[857]: rsync disabled, removing Dec 4 09:14:23 gaback xinetd[857]: time disabled, removing Dec 4 09:14:23 gaback xinetd[857]: time disabled, removing Dec 4 09:14:23 gaback

RE: [expert] Network problems caused by 'Tiny Firewall' GUI in MDK
I have the 8.1 powerpack here, and it comes with a install and user manual and a reference manual.. I will have a look in there for the tiny firewall details.. I haven't looked back see your initial question, but you might try looking in /etc/sysconfig/iptables I think that may be where tiny firewall keeps its rules and stuff. I know one thing, for simple readability, ipchains beats the hell out of iptables.. I have still not found a simple script platform like pmfirewall that asks a bunch of questions in a console at install then writes a nice easy to read list of rules, one per line with nice comments on them, closes all the obvious gaps, and is really easy to modify and add to... I have a massive list of rules in my 7.2 box in ipchains and ipmasqadm, and I had the firewall setup to allow different ports open on 7 of my domains being hosted on that box.. Its tough to figure out how I am going to do it easily in iptables. I have a basic script, but nothing that does all that I want yet.. wish someone had written an online ipchains - iptables script with Javascript or something, that would be very handy.

Re: [expert] Network problems caused by 'Tiny Firewall' GUI in MDK
Mr. Woods Thank you very much for replying to my post. port 139 I was leaving open for samba. I use samba so that I can download stuff straight from the internet to my linux box from my Win2K box.

Re: [expert] network problems
Check out the "route" command. It is possible that your gateway is the wrong device. All installs of Mandrake on my machine (and recently a laptop at work) have had the gateway default to either the wrong device or ip number (.254) which kills network function stone dead - packets go out, but nothing comes back (of course) BillK Robert wrote: Hi Tom, I've had very similar problems.

Hi, I had some thing simmilar (not the same) where comp A would receive pings from either comp B or comp C but not could not reply. I had two NIC's on comp A and they were both on the 192.168.1.0 network. It turned out that this caused an ambiguity. This is because it is assumed that if there are two routes to the same network, then all hosts on that network can be accessed via either route. Hope this helps. CjD
Re: [expert] network problems
No!! Messing about with the route and ifconfig commands never worked in my case at least. After the ifdown/ifup sequence the routes are unaffected anyway.

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

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?

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.

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 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. Here is a very basic ipchains example to get your eth1 local net to forward through to eth0. ipchains -P forward DENY ipchains -A forward -i eth0 -j MASQ Mike - Original Message - From: Herman Van Keer (softouch) [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, September 16, 1999 12:09 PM Subject: Re: [expert] network problems on Mandrake 6 The funniest thing too is that the card seems to be dead - no lights (the one of the external network eth0 - while eth1 is on) Another funny thing is, when I do a reinstall with RedHat 5.1 = no tweaking whatsoever (apart from inserting the eth1 in /etc/conf.modules) - and that just works fine.

Check ifconfig, is it recording TX/RX errors or colisions or anything of that nature.

I can ping the internal network 192.168.42.xx Try reversing the cards maybe, like swap the alias eth0 for the alias eth1. If you know what i mean then you will know if it's the card/driver or the config .

[expert] network problems on Mandrake 6
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
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? Some more information on the structure of the network and how everything is connected would be helpful.

Mike Thanks Mike for this turbo-quick answer;-) Unfortunately, I have now the 'old' 5.1 setup. Just give me some time I'll reinstall Mandrake and give you the information. Thanks a lot, Herman BTW: somebody wrote me RedHat 5.1 (2.0.35) is buggy??? So I definitely should upgrade .
