Operations hang for ~60 seconds after loopback device is initialized
Posted on 2003-03-03
The following operations take a long time to execute after I did a "ifconfig lo 127.0.0.1":
- ps -ua, ps -ux (but ps -u and ps -ax are both fine)
- logging in (delay after I typed user, password [enter])
- Running "skill" (kill is fine)
- ls -l (when there is an unkown numerical group or owner to be listed)
I'm using Linux 2.4.20 and I just tried upgrading to the latest net-tools 1.60. I'm running totally off a CD where my /usr tree is entirely read only. (The rest of the system has been loaded as a RAM disk). This is my own Linux distribution that I raised from the sources myself.
I'm doing this ifconfig myself manually at the command prompt. The system by itself initializes the bare minimum multi-user environment. (No networking whatsoever).
The lo device pings just fine and shows up as UP RUNNING in ifconfig after I brought it up. If bring it down (ifconfig lo down), the problem remains: a reboot is required for these operations to be quick again.
What could the cause to this problem be?
