Problems with telnet and ksh

Joshua Leckner_1 — Mon, 04 Mar 2002 16:05:10 GMT

When i log into a machine with a user that has a korn shell ....the machine sources the local profile....sources the users profile....but stops after that point and never returns to the shell prompt. Sometimes a control C will break it....but not always...

If i log into this machine with a c shell...then change into ksh...then source....its ok. But logging into the machine with a ksh doesn't seem to work.

Any hints or ideas??

The /etc/shells files is there and valid. The shells are there as well.

Thanx for the help.

Hi,

Is the user home directory on NFS mounted directory. If so you can have the user shell history redirected to the tmp directory instead of the NFS mounted home directory.

Hope this helps.

Hi,

Try this link,

http://us-support3.external.hp.com/cki/bin/doc.pl/sid=aeec5d2503ddd01e98/screen=ckiDisplayDocument?docId=200000026056389

This is the solution suggested,

//Quote//

Solve the problem of ksh/sh hanging when the home directory is NFS mounted by setting HISTFILE to point to a locally mounted directory such as /tmp/.sh_hist.$LOGNAME.

//EndQuote//

Hope this helps.

Can you post content of the user profile ?

add the -x to the user's .profile to throw it into the debugger so you can see where it hangs:

#!/bin/ksh -x

Hi,

Check your user profile for any problems. Try renaming it and login. Also check whether the home directory has any big files ( sh_history).

What about loging for 'sh' ? Is this happens to only one user ?

The users profile is below...
#####
/bin/ksh

clear
ls
####

eof

This is just for testing purposes....

it may be hanging on the "clear". Set the "TERM" variable just above it to match their terminal type.

Heres one....

Having the same issue with a 10.20 machine...

But this time...it nevers gets to the users profile....it hangs on the system profile after it prints out the /etc/copyright.

any ideas???

Mark Greene_1 — Mon, 04 Mar 2002 16:21:50 GMT

the next item after the copyright file is the message of the day. do an ls -l on /etc/motd to make sure it exists and the permissions are -rw-rw-rw-

also run fuser against /etc/motd to make sure no other process has a lock on it.

Here is the updated users .profile

#!/bin/ksh
HISTFILE=/tmp/.sh_hist.$LOGNAME
TERM=vt100
clear
ls

On the 10.20 and 11.00 machines...it now logs in perfectly...but when i do a..

$ . .profile

...the machine replys with..

ksh: .profile: not found

The /bin is within the profile and a command below works fine...

$ ksh . .profile

any ideas??

you probably do not have the . (current directory reference) in your path variable. this is a good thing. try it like this:

. ./.profile

hey Mark...

That seems to work.

What do I need to do so that the user only has to type in

. .profile

to source there profiles after login??

Re: Problems with telnet and ksh

Mark Greene_1 — Mon, 04 Mar 2002 18:13:35 GMT

they should not have to explicitly source it if you have their home directory setup in /etc/passwd--or are all the users logging in with a generic ID?

No.

This specific account is an Oracle accout. I have multiple .profile files created to source the correct variables for differnt versions of Oracle. So..the may log into the machine....but they will need to source in the appropriate .profile for the specific version / OS they want to test with.

Re: Problems with telnet and ksh

Mark Greene_1 — Mon, 04 Mar 2002 18:27:38 GMT

ok. your best option is for them to do the pathname reference, . ./.profile

you really do not want to add the "." reference into the PATH variable, as there are too many potential gotcha's involved that will only cause more problems.

Hi,

Try this from any directory,

$ . $HOME/.profile

Note the "." before $HOME

This will source the .profile of the user from his home directory.

Hope this helps.
