ok i need to stop a user from telneting a system on which it has a valid account and just allow him ftp and no other servives should be effected. The system is ultra 60 with solaris 7 installed. I cannot use the option of making the user shell as /bin/false because it stops both telnet and ftp and if i create an /etc/shells file then i have to put in all the valid shells which somehow my customer does not want to do!!

Naufal,
/bin/false & /etc/shells is the best way to do it.
Another possiblilty is to use setfacl to remove the execute and / or read bit for that specific user to their shell or another executealbe telnet needs but ftp doesn't.

so if user_1 uses the ksh
setfacl -m user:user_1:r-- /usr/bin/ksh
