Hi Jonathan, > ipchains and ip tables can not be used together [Warning] Run ntsysv as root and disable ipchains. > Determining IP information for eth1...failed; no link present.

What are the contents of /etc/sysconfig/network-scripts/ifcfg-eth1? > redhat-config-network: Error saving configuration! > [Errno 2] No such file or directory: > //etc/sysconfig/network-scripts//ifcfg-lo.rpmsave > > If I do cd /etc/sysconfig/network-scripts and do ls, what I can see is that > file (ifcfg-lo.rpmsave) but it is surrounded by a brownish-red background > which is flashing. If I do "less ifcfg-lo.rpmsave" I get the message, "No > such file or directory." Probably a dead symlink. What is the output of ls -l /etc/sysconfig/network-scripts/ifcfg-lo.rpmsave ? Does the file /etc/sysconfig/networking/ifcfg-lo exist? If so make a new symlink to it: ln -s ../networking/ifcfg-lo /etc/sysconfig/network-scripts/ifcfg-lo If it doesn't exist create it first with the following content: DEVICE=lo IPADDR=127.0.0.1 NETMASK=255.0.0.0 NETWORK=127.0.0.0 # If you're having problems with gated making 127.0.0.0/8 a martian, # you can change this to something else (255.255.255.255, for example) BROADCAST=127.255.255.255 ONBOOT=yes NAME=loopback and after that create the symlink as mentioned above. Try again and tell us the result. Bye, Leonard. -- mount -t life -o ro /dev/dna /genetic/research
