Hi all... I am a Linux newbie trying to install CentOS 4.6 Linux in a z9
LPAR. This is a no money, proof of concept type project.
We booted from the HMC DVD drive, ran thru the install, and loaded the
applications via ftp. Everything seemed to go smooth until we shutdown and
booted from disk. Linux comes up and seems to be fine from the HMC console
but we no longer have network connectivity (OSA Express2-FEth non-QDIO).
From Linux it can ping itself, but nothing on the outside. From the outside,
FTP, telnet, and ping all time out trying to connect to Linux. I looked at
/etc/sysconfig/network-scripts/ifcfg-eth0 and did a "ifconfig eth0" command
but don't see anything obviously wrong (although I haven't found out what it
is using for a router/gateway yet). Right now I don't know where to check
other tcpip parms like gateway, etc.
Has anyone had a similar problem or can you tell me some things to check? I
don't speak much Linux but there are a couple of guys here that can help.
Show is the output of "ifconfig -a"
I presume that since you "don't see anything obviously wrong" that
ifconfig actually sees the network device.
Do you have a dhcp server on the network? If so, "dhclient eth0" should
get the interface up and going while you think things over.
Otherwise (using IP addresses you're supposed to be using, not these)
ifconfig eth0 192.168.1.1
route add default gw 192.168.1.254
For more.
man ifconfig
man route
You could also inspect settings with this command:
system-config-network-tui
or if you have graphics (not really recommended)
system-config-network-gui
btw You can also get _real_ RHEL free of charge for evaluation.
