Cetin,
 
1. check out 'man rexec' 'man rlogin' - should give you something.
 
2. inetd.conf. : set the -h flag on the rshd. then all is open including
                      superuser-commands. if you don' t want it that permissive
                      use -l, AFAIR. man rsh and so on.
3. configure .rhosts files or /etc/hosts.equiv.
 
4. for more security check out kerberos, dokumented on the above man-pages.
 
well, that' my 2p worth.
good luck

Betreff: [suse-security] rexec-connection

hallo all,
 
i have some programs which are using the rexec connection (like an X-Windows-Server or Mathematica with a remote kernel).
When i try to connect i get the message 'can't open socket' or 'connection refused'. How can i enable this kind of connection
and is there a security problem with the remote-exec. In the /etc/services is  a port (standard) exec  512/tcp.
 
Thanks in advance,
