Available ports

[leco]

This is another of those - I know it's in there somewhere - questions. How do I get a list of open or available ports on a 2003 server?

 

I'm trying to use Snap Deploy and am told that I need TFTP service running on port 69. I've tried to telnet into that port but get a not connected message. I've used netstat -b but 69 doesn't feature anywhere in the list. Is there another tool that I can use to find if the port is available/open?

I'd be thinking in that case it's not running.

 

I'd typically use netstat on the local box and telnet from afar to check it out.

You could scan for open ports, and the applications using those ports using nmap.

 

nmap -r "ipaddress"

 

Will list all ports and class there status and give the application running on them

 

nmap -p69 "ipaddress"

 

Will scan for just that ports status

Try netstat -an instead, b alone is only going to show those ports that are connected

Thanks I'll have a go with those in the morning.

I've always used PortQRY. I think it's part of one of the resource kits... but it's available from ms.com too

That looks useful, thanks.

If you haven't set up a TFTP server, it won't be running...

I was kind of assuming that Snap Deploy would have done that on install. If not how do I do that?
