Hi All, I upgraded my server to 8.10 today and things looked really good. Unfortunately, name resolution is no longer working! Here's some info: 2.6.27-10-generic #1 SMP Fri Nov 21 19:19:18 UTC 2008 x86_64 GNU/Linux I am running ISPConfig with it's own DNS. When I lookup one of my domains against my own name server things work fine: Code: dig @localhost www.cocoanet.us ; <<>> DiG 9.5.0-P2 <<>> @localhost www.cocoanet.us ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 38226 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 ;; QUESTION SECTION: ;www.cocoanet.us.

But I can't get it to resolve at all with the proper resolv.conf without the network manager packages. I also removed apparmor thinking that may have something to dow with what's going on but no luck. Also, if I dig against my DNS with someone elses domain here's what I get: Code: dig @localhost www.covad.com ; <<>> DiG 9.5.0-P2 <<>> @localhost www.covad.com ; (1 server found) ;; global options:

Also, covad's DNS is OK as I'm connecting through the same network with my laptop.

Oh, once I'm into the server via ssh to eth1 then I can ssh to all the IP addresses and netstat -tapn looks good! One thing that's also weird: Code: 74.1.46.160 0.0.0.0 255.255.255.240 U 0 0 0 eth0 74.1.46.160 0.0.0.0 255.255.255.240 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 74.1.46.161 0.0.0.0 UG 0 0 0 eth1 I thought there should be a GW for each IP address???? Also, I can ping out from the server, and can get to all websites that I want to use, but can't get in. I think Network-Manger is to blame, but I can't seem to figure out what is going on here
More Information: I removed the network-manager package again and moved it's startup scripts,etc to make sure it doesn't start. Now, if I run 'ifup eth0' things work just fine. If I then run 'ifup eth1' then things break again. I see that there may be some new items in /etc/network/interfaces, specifically the "network" tag. Do I need this???? The routing table looks hosed up really good to! Do you or anyone have a good /etc/network/interfaces file that has multiple NICs and multiple VIPs??????? I think it's now getting hosed on the syntax for doing such a thing, but searching the internet and forums doesn't help. HELP!!!!!!

Hi Falko, I'll give that a try. I'm really baffled about this. I've cross-posted to ubuntu forums with no responses there. Here's the link if you want to take a look: http://ubuntuforums.org/showthread.php?t=999433
Fixed: Appears that syntax that used to work in /etc/network/interfaces, no longer works. Basically, you need the to specify the IP, Netmask, Broadcast, Network and on only one interface specify the gateway. Looks like if you have multiple gateway entries for the same gateway things get really confused. Here's my /etc/network/interfaces that works: Code: auto lo iface lo inet loopback iface eth0 inet static address 74.1.46.162 netmask 255.255.255.240 broadcast 74.1.46.175 network 74.1.46.160 gateway 74.1.46.161 iface eth0:1 inet static address 74.1.46.163 netmask 255.255.255.240 broadcast 74.1.46.175 network 74.1.46.160 iface eth0:2 inet static address 74.1.46.164 netmask 255.255.255.240 broadcast 74.1.46.175 network 74.1.46.160 iface eth0:3 inet static address 74.1.46.165 netmask 255.255.255.240 broadcast 74.1.46.175 network 74.1.46.160 iface eth1 inet static address 74.1.46.166 netmask 255.255.255.240 broadcast 74.1.46.175 network 74.1.46.160 iface eth1:1 inet static address 74.1.46.167 netmask 255.255.255.240 broadcast 74.1.46.175 network 74.1.46.160 iface eth1:2 inet static address 74.1.46.168 netmask 255.255.255.240 broadcast 74.1.46.175 network 74.1.46.160 iface eth1:3 inet static address 74.1.46.169 netmask 255.255.255.240 broadcast 74.1.46.175 network 74.1.46.160 iface eth1:4 inet static address 74.1.46.174 netmask 255.255.255.240 broadcast 74.1.46.175 network 74.1.46.160 auto eth0 auto eth0:1 auto eth0:2 auto eth0:3 auto eth1 auto eth1:1 auto eth1:2 auto eth1:3 auto eth1:4
