Ok...so you then went into smitty devices....? after you did the ifconfig stuff
from above?
If you go into the smitty devices, communication, ethernet adapter and set
the media speed, and half or full here,
If the card is up it will say busy...so save changes to database only
and you set for 10 or 100 not auto?
And you then went into smitty tcpip, minimum configuration
And you selected your adapter and checked that there was an IP and
Hostname and gateway? and you moved the cable to the new card?
When you are done, you should check the /etc/hosts file to make sure there is
an entry for lo0 (your loopback at 127.0.0.1 and that you do not have any
duplicate entries. If you had an entry for one IP address and you changed it,
make sure the original is removed.
Make sure there are no spaces before the entry for the loopback entry. If there
are you may have problems with NFS as well. Usually you get a E18E984F
label or a 256-9020 for the rpc.mountd.
If you cannot ping yourself, it is probably that the loopback line is missing or
incorrect. Check the rc.net file. Is the entry for the loopback line commented
out?
The line should be
/usr/sbin/ifconfig/lo0 inet loopback up >> $LOGFILE 2>&1
