cvs pserver login problem

[lectrix]

hi!
i am reposting this since i forgot to fill in the subject field last time, 
sorry!
keep hoping someone can give me a hint on this:

i am experiencing a problem with setting up cvs pserver. i followed the 
instruction in the manual and configured xinetd so that it starts cvs 
pserver on port 2401 successfully ( i tested with telnet). but when i am 
trying to connect, syslog says: "www xinetd[26206]: START: cvspserver 
pid=26228 from=$IP... www xinetd[26228]: FAIL: cvspserver address from=$IP" 
and on client side i only get "cvs [login aborted]: reading from server: 
Connection reset by peer", i checked everything mentioned in the manual and 
couldnt find the error...
here is my login command:
address@hidden lectrix $ cvs -d :pserver:www.symbion.at:2401/home login
Logging in to :pserver:address@hidden:2401/home
CVS password:
cvs [login aborted]: reading from server: Connection reset by peer

and CVSROOT ist
address@hidden lectrix $ echo $CVSROOT
/home

i heard of some reverse lookup problems, but i can do reverse lookup on the 
system by simply doing "host IP", that should be it?!
can somebody help please?
thanx. stefan.
