fanyong — Mon, 29 Oct 2001 09:22:45 GMT

I run this command

# chown -R data:data /usr

when telnet to this system ,it told me
"Unable to set uid/gid"
and close this Connection.

Hi,
you have committed a big mistake. some of the files/directories /usr are owned by root/bin/system. You need to change the ownership of the files by looking at the another system which works fine. Or if you have ignite backup just restore from backup. if you want only telnet to work at present just do # chown bin:bin /usr/bin/telnet

Hi,

You should not have run a chown data:data
on /usr. There are many directories that
have files that have ownership crucial to
the system. looks like you have flattened
the shells so that you can't login normally.
You can do one of two things, if you are
logged in already check with another system
for it's directory structure or restore it
from backup tape.

Here is a link to a similar problem, but in that case, the user changed permissions from / down:

All systems ( UNIXs) have their own software installer, and usualy a revorever.

in HP-UX this is swverify - man 1m swverify-. Check it.
