I connected to my remote server through ssh by using my root account
all command were executing normaly
but suddenly
permission denied Error occurs like following

[root@dsas]#ls
permission denied
[root@dsas]#cd /tmp
permission denied

and when i open new terminal and connected by using my root Account
then it behave normaly.

Sir i want to ask that is any permission can apply from any console to any console regardless less both are root user.
for example
pts/1 -------------->has root
pts/4------------------>has root
Then pts/1 user (root) can restrict pts/4 console root user or not please tell me.

I am wondering whether you have somehow logged in with a restricted shell, which would deny these commands & others.

check out:

man sh

looking at the -r option & the RESTRICTED SHELL section which is at the end of a very lengthy man page!

Hop this helps you out.

Thanks Sir for ur coopration
But i can't understand how to use this documentation please give me some examples

Open a shell and type:

man sh

That will give you the manual page for the shell. The space bar moves pages ahaed. Hitting q will exit the manual.

Good luck.

One think to do is to disable root login to SSH as it's a big security risk. Edit /etc/ssh/sshd_config or whatever the file is called in your distro.

Find the line which enables root login and disable it. You should be able to login as plain user and then swithcing to root user which is more secure.

We need more information about the setup of the remote server, to figure out how to help you. If the server has been setup by it's administrator to have your login go into a restricted shell, then there isn't much that you can do from your end, apart from contacting the sys admin.

I mentioned the sh or bash man page so that you see how restricted a restricted shell is & see whether this matches the problems you are having.

I am also wondering why/what you need access to on the server. If you are supposed to have access, then the sysadmin should setup your login, so that you have access to the resources that you need.

There is an article all about ssh in the newbies section.

I hope this points you in the right direction, and look forward to your reply with info on the remote server.
