"su -" in terminal hangs

Hi All,



I use FC18 box (3.9.4-200.fc18.x86_64) for ssh-ing to other boxes. 

It was working normally without rebooting for months but now when 

I tried to put "su -" in the terminal, it hangs.




I haven't found any help in Internet.




Any idea? Please advise...




Thank you so much.

Does it work if you use "su" without the dash?  If so, there might be 
something in /root/.bashrc that's hanging.

Dear All,



Sorry to be late, I was out for holidays.




Thank you all for your kind help. Finally I solved it, but a stupid

MS way. I stopped all processing and restarted the box. After

rebooting the "su" works normally. 




I feel shame for such "resolving" (actually it stays unresolved) 

but I hadn't time enough to investigate it more.




Thank you so much for your kind effort and help.

Do you get a password prompt, or does it hang before that?

See
http://www.linuxquestions.org/questions/linux-enterprise-47/console-hangs....
 Is 127.0.0.1 in /etc/hosts?

See https://bugzilla.redhat.com/show_bug.cgi?id=129045  What might be in
the various .bash files in /root?  grep -i path .bash* in /root

If you CTRL-ALT-F3 to a new console, can you login as root?  That is, is
this a root problem or an su problem?

Thank you for thinking about it. :)
Also "su" only (without "-") was hanging. The /root was 550 as
before.

Does simple 'su' work? Is the home directory for root readable? Just a
few questions that popped into my head.

Hope this helps,

Nonetheless, it should not hang.

Where does an "strace -f su" stop? It may abort early anyway (strace
doesn't go across an suexec execution) but if the problem is earlier
then it may tell you something.

Also, can you run an ordinary login as root, either at a console
or by running "login"?

Shouldn't it be 770?

Another thing you could check is entries in /var/log/secure.  If it is a
pam problem, it should show up there.
