Not if the file is owned by root, with no other permissions. 2) If you allow telnet access, you have more problems to worry about. Such as anyone with access to your local network, or your Internet provider's network, being able to capture your login passwords. </blockquote> Sorry, How can we limit a user a/c when telnet ( ssh-telnet ) to the server : eg : login as: edward <a class="moz-txt-link-abbreviated" href="mailto:edward@192.168.0.1">edward@192.168.0.1</a>'s password: Last login: Wed Feb 7 11:56:44 2007 [edward@svr1 ~]$ ls -l -a total 36 drwx------ 3 edward edward 4096 Feb 6 22:51 . drwxr-xr-x 5 root root 4096 Feb 6 22:50 .. -rw------- 1 edward edward 45 Feb 6 23:09 .bash_history -rw-r--r-- 1 edward edward 24 Feb 6 22:50 .bash_logout -rw-r--r-- 1 edward edward 176 Feb 7 11:57 .bash_profile -rw-r--r-- 1 edward edward 124 Feb 6 22:50 .bashrc drwxr-xr-x 3 edward edward 4096 Feb 6 22:50 .kde -rw-r--r-- 1 edward edward 658 Feb 6 22:50 .zshrc [edward@svr1 ~]$ Prevent user "edward" from modifing / deleting the exiting ( dot ) files ( default by the system ).
