I just did a fresh install of centos 5.0 from cd, followed by yum update
which installed 399 packages. No failures or errors that I can see.
I have three nics in the box, but am only setting up one at the moment.
The box can ping others in my network, but if I try ssh, telnet, ftp, etc
I get this:
[root@cm network-scripts]# ftp watchdog
ftp: connect: No route to host
ftp>
[root@cm sysconfig]# ftp 172.17.2.242
ftp: connect: No route to host
root@cm network-scripts]# telnet watchdog
Trying 172.17.2.242...
telnet: connect to address 172.17.2.242: No route to host
telnet: Unable to connect to remote host: No route to host
[root@cm network-scripts]# ssh -l campbell watchdog
ssh: connect to host watchdog port 22: No route to host
The weird part is I can do this:
[root@cm network-scripts]# ping watchdog

and I can do this:

and it will connect fine.
