Port 4644?

February 26, 2004 7:59 PM

My router tells me that many IPs are trying to connect to my PC on port 4644. Why?

Here's what my log file looks like:

82.83.67.202 4644
82.84.172.8 4644
82.83.67.202 4644
61.42.129.162 4644
80.36.213.139 4644
61.42.129.162 4644
80.36.213.139 4644
80.36.213.139 4644
80.36.213.139 4644
67.68.177.23 4644
62.211.216.206 4644
81.51.197.166 4644
81.51.197.166 4644
62.211.216.206 4644

My first thought is that someone's connecting to your site through a proxy of some sort, perhaps from behind a firewall. Do some of your readers access the site from work? If so, that may be it.

Isn't that SoulSeek's port of choice?

Your search - soulseek "port 4644" - did not match any documents.

Yeah, that's not it (I'm away from home). I just remember seeing this in a port scan I ran a month or two ago and getting all freaked out until I figured out what it was. But now I forget. So that's helpful.

Could that be some sort of ICMP traffic? I know ICMP is portless, but could the number be some sort of decimal encoding of the ICMP code?

It seems port 4644 is a popular port for proxies to run on. Which means...

People are probing you to see if you have an open proxy. Spammers love these to cover their tracks.
