hi there. i recently upgraded from rh4.2 to rh5.2 and have since
upgraded the kernel to 2.2.1. i have no loopback on bootup.
'ifconfig' returns nothing. netcfg (nettool ??) shows the loopback
and my eth0 as present but lo does not activate when i click
i've tried doing 'ifconfig lo up'; it creates the loopback but 'ping
localhost' gives errors (network unreachable, i think) and 'telnet
localhost' immediately closes the connection. i get the same thing if
i do 'ifconfig lo 127.0.0.1'. i tried also doing 'route add 127.0.0.1'
but i get an SIOADDxxx (don't remember exactly) error.
i've found the ifcfg-lo in /etc/sysconfig/network-scripts, but i don't
know when this is called and by whom.
can someone give me some hints on how and when the loopback device is
created?? i have changed the config of the kernel (enabled smp,
sound, network card, etc) but i didn't see any config options for the
network loopback. (there is a loopback but it's used for block
devices; drives, etc, i believe. i've enable that one anyway.)
