just want to check out soft by svn, but failed for 'connection refused' reason

e.g.

svn: Can't connect to host 'svn.mplayerhq.hu': Connection refused

and this is my iptables status and some info to confirm the DNS and ICMP connection are ok.

=========================

service iptables status

iptables: Firewall is not running.

PING svn.mplayerhq.hu (192.190.173.45) 56(84) bytes of data.

64 bytes from avserver.banki.hu (192.190.173.45): icmp_seq=1 ttl=49 time=200 ms

=========================

so, anyone knows the reason?

my system is centos 6 with 64bit

thanks
