Detect if port is being blocked by my host?

Yarin · 10-21-2009, 05:18 PM

Is there a way to find out if a web host (shared server, not dedicated) is blocking certain ports (right now, specifically, 1129)?
I read that if the port isn't being blocked, that it'll be "open". Which made me think about running a port scan, but I was hoping to find a more reliable, unobtrusive, and faster way of finding this out.
Any suggestions?

Well, I'm pretty sure each operating system offers their own unique solution to this, but seeing as you didn't tell us which you're using, I'll just have to give the cross-platform solution of using the internet.

Online Ping, Traceroute, DNS lookup, WHOIS, Port check, Reverse lookup, Proxy checker, Mail relaying, Bandwidth meter

Enter the domain, select Port Check, enter the port, click Go.

Without using the internet however, most operating systems support telnet. I think you have to enable it in Vista and Windows 7, though.

EDIT: Hmm, probably should have looked at your sig. Fedora will support either of the above.
