A problem recently arose on a Sun 386i, running SunOS 4.0.2, belonging to
a friend of mine. His girlfriend was doing some work on it, running as
'root'. She inadvertantly used the 'hostname' command to change the name
of the workstation. The syntax, as best as she could recall, was
hostname chenxi
No problems were seen until the workstation was rebooted. By default, Sun
386i's run Yellow Pages (NIS). And her mistake caused NIS to go bug-
whacky and fail to reboot in multi-user mode. The problem surfaced during
the loading of the YP daemons. The error message was
yp server not responding for domain "YP.noname"; still trying
Now, I have a similar machine, and I have his system disk mounted as my
system's auxiliary disk. Hence, I can edit any file on his system disk
to remove the corruption. I know his original system's name. Now for
the big question.
What file(s) did 'hostname' modify ??? I first checked /etc/rc.local. No
soap. Then I did a 'grep -e chenxi *' in /etc. No soap. Where in the
heck did 'hostname chenxi' do its dirty work ?!?!?
Once I know this, my friend's system disk will be golden _very_ soon.
If you respond by email, please do so to my NASA adress:
croten@eosdata.gsfc.nasa.gov
to save disk space on nyx's chronically diskfull system.
Thanks in advance.
