my company decided to test the use of linux on database servers. My colleagues and me play around with oracle linux (based on RHEL5, afaik) at the moment and configure the network.
We heard in a short introduction that network interfaces can be configured with ip and ifconfig.
Bringing eth0 down with these commands (ifconfig eth0 down
and ip link set eth0 down
) work as they should. When we try ifconfig eth0 up
or ip link set eth0 up
, we get no error message. But when we try to ping another host, it tells us that the network is not reachable.
The only way to reactivate the interface is using the ifup eth0
command - the only one of the three, which has no manpage (which I found rather odd).
Is this normal or did I misinterpret the manpages of ifconfig and ip? English is not my first language, so I might have misunderstood something..
Thanks in advance!
PS: I searched google and used the forum search, but you don't get many useful links when looking for "ip link set up" or "ifconfig"... especially when "ip" and "up" are not possible to search for in the forum because they're to short.
So please don't jump on me if the question has already been answered here, I tried my best
