facing problem while using CVS

Hi All,

I am facing problem while using CVS. I am working on Solaris 10 and
trying to fetch source code of Postgres as " Anonymous CVS" as follows
:

/$ cvs -d :pserver:anoncvs@anoncvs.postgresql.org:/projects/cvsroot login /

(url : http://developer.postgresql.org/docs/postgres/anoncvs.html 
<http://www.google.com/url?sa=D&q=http://developer.postgresql.org/docs/postgres/anoncvs.html>) 


after providing password I am getting error :

/Unknown host anoncvs.postgresql.org. /

I even tried it with :
/ $ /usr/dist/share/socks/bin/runsocks cvs -d 
:pserver:anoncvs@anoncvs.postgresql.org:/projects/cvsrooot login /

still i got the following problem :

/ cvs [login aborted]: connect to 66.98.251.159(66.98.251.159):2041 
failed: Connection refused
/

can anyone help me in this regards

Thanks in advance,
Saurabh
