Many installs of RHL 7.3 will add both ipchains and iptables. It could be that iptables is running instead of ipchains. I believe that both are actually compiled as modules so you might need to rmmod the one in order to use the other.

by Richard Goodman

Well, I've got the ETH1 and DHCP issues resolved (Thanks, Charles). Did not need to do anything with modules - had misinterpreted the install dialog and ifcfg-eth1 had BOOTPROTO=dhcp. eth1 should have been static with DHCP running from there. One unresolved issue - when I issue an IPChains command, the first time I get "IPchains incompatible with this kernel" and thereafter "IPChains protocol not available". The IPChains command is there, as for example "ipchains -h" works. But I haven't got masquerading or firewalling yet because of this.

These are PCI cards, right? Then you don't need any of that. The PCI BIOS autoconfigures the IRQ's and addresses. What you can do is: /sbin/lspci -v and check to see if your Realtek shows up there. In there it should also have IRQ's and addresses assigned. This command should get things going manually: /sbin/modprobe 8193too After that, check "dmesg" output and see if there are any error messages about loading 8139too. If not, "/sbin/ifup eth1" should start up the network on that interface. -- Charles R.

Server For Sale

by JV

Sometime around April I bought a server from Dell. The plan, at the time, was to make it into a webserver and host Wormtown.org and whoever else I could split the bandwidth/hard drive with at a hosting facility in Marlboro. However, it was also in April that I lost my job and then determined that the donations that Wormtown.org collects are not nearly enough to cover the cost of hosting. So, now that I've been unemployed since April. I'm feeling the money start to tighten up and I think it's about time to sell this server. It is a Dell PowerEdge 1650 http://www.dell.com/us/en/esg/topics/esg_pedge_rackmain_servers_1_pedge_165… It is a 1U rackmountable server. It has one PIII 1.13 chip in it It has 512M of RAM (2x256) It has one 36G drive (U160, 10K RPM) The rest of the specs are standard. I've got all the CDs including the Dell Drivers CD and the Red Hat 7.2 Discs that came with it. I've even got Rack Rails. And it does have the cool blue Dell logo that lights up on it. It's been run for about 15 hours total. I believe I paid a bit over $2100 for it. I just priced the same exact machine for $2071 (plus tax and shipping) at Dell.com. I will, of course, take the best offer I can get. I don't want to go any lower than $1500 if I can help it, though. If you're interested, or someone you know might be, contact me.

Re: [Wlug] RH7.3 Questions

Charles, Thank you for your detailed response. Your answers to Q 3-7 close those issues. On Q2, yes I really mean to run dhcpd to issue IP#s to selected client machines on the internal network. I'm confident that my dhcpd.conf is correct, and it is called by "dhcpd eth1". This was running under RH7.0. I installed the dhcpd RPM off the 7.3 CD (don't have version info here) Since I first wrote, I went back to the new server and banged my head on it for a couple more hours, remarkably getting answers to some of your questions. 1a) ifcfg-eth1 does have "ONBOOT=yes". I will post it when I get back to the server in the morning. 1b) /sbin/ifconfig shows only "lo" and "eth0" and nothing for "eth1" 1c) There is no /etc/modules.conf file on my machine. 1d) I think the module is 8139too, because when I temporarily pulled the Realtek card (eth1) I got a message during the attempt to startup ETH1 complaining about that module by name (did not get complete message). I did some fiddling with modprobe (which I don't understand) after reading section 2.3 of the Ethernet How-To (Using more than one Ethernet Card per machine). From the startup post screen I can see the Ethernet cards are on IRQs 10 & 9, and from the ifconfig I see that eth0 is 0x8000, but I couldn't get the address for eth1. Do I need it?

Edit /etc/sysconfig/network-scripts/ifcfg-eth1 and make sure "ONBOOT=yes" is in there. Could you post that file so we can look at it? Run "/sbin/ifconfig eth1". What does that show?

Note that this might not be flexible enough e.g. if you get a dynamic IP address from your ISP, in which case the rules might need to change slightly each time the firewall script is run. If you do use the above method, you'd need to make sure IP forwarding is also turned on in /etc/sysctl.conf. An alternative to using the /etc/sysconfig/ipchains and sysctl.conf stuff is to put your firewall script into /etc/sysconfig/network-scripts/ifup-post.

RH7.3 Questions

by Richard Goodman

I have a RH7.0 server which has been giving me regular unrecoverable disk errors since 6-8 weeks ago. I figured today I had enough time to do something about it. I also figured that as long as I had to rebuild from scratch (after installing a new hard drive) I'd upgrade to RH7.3 -- but I have a few more problems that I figured on. The server is dual homed - eth0 (DEC 2104x 10mbps tulip driver) goes to DSL, eth1 (Realtek 100mbps) goes to internal network. Was running IP Masquerade / IPChains / Apache / sendmail / DNS server fine under RH7.0 I have the following problems: 1) During startup eth0 comes up but eth1 does not. My notes on the previous installation [year ago?] don't show that I did anything special when I installed the Realtek (was previously also DEC 2104x) but that doesn't mean I just didn't write it down. 2) dhcpd won't run, but I assume that's related to #1. Was surprised that dhcpd wasn't loaded during install, as I flagged eth1 as dhcp. 3) how do I know whether IPchains or IPtables is active, and how do I switch. Considering the time involved so far, I think I'd rather delay switching to IPTables and use my existing IPChains firewall for now. Can I still hook it in at the end of rc.local? 4) During install I did answer some firewalling questions (set to medium, custom) -- where is the results of that dialog? 5) If I can use my existing IPChains firewall, that will take care of IP Masquerade -- if not can I have some guidance as to what direction to take. 6) httpd comes up but says "cannot resolve hostname, using 127.0.0.1" - what did I forget to configure? (I haven't touched httpd.conf yet.) 7) issue and issue.net used to be set from rc.local, but no more -- where are they set? I'd like to patch that out and be a bit more anonymous. I'm definitely unconnected until most of these Q's get resolved. Thanks to any who can assist me. Dick
