If it's a linux server ... "netstat -tula" should show you what ports are listening and established. and "grep 37549 /etc/services" would should you if that port is registered with the system for anything (although that doesn't mean it being used, or will be used). Matt

I run command middle on original server : [root@localhost /]# service iptables restart Flushing firewall rules: [ OK ] Setting chains to policy ACCEPT: mangle nat filter [ OK ] Unloading iptables modules: [FAILED] ?

I think, you dnt have iptables modules installed on your VPS. Also, regarding the netstat, it will diplay port, only if there is some services running on it.
