Simple Relay: random unknown UDP port in listen mode
Hi,
I'm setting up a simple Tor relay (no exit), and it went fine, until I saw that a unwanted port was reported: it's a port that does not show up immediatly when starting tor daemon, but after a while.
Right after tor start:
netstat -lpnut | grep tor
tcp 0 0 0.0.0.0:8890 0.0.0.0:* LISTEN 22278/tor
tcp 0 0 0.0.0.0:8891 0.0.0.0:* LISTEN 22278/tor
After a while, a random UDP port shows up:
netstat -lpnut | grep tor
tcp 0 0 0.0.0.0:8890 0.0.0.0:* LISTEN 22278/tor
tcp 0 0 0.0.0.0:8891 0.0.0.0:* LISTEN 22278/tor
udp 0 0 0.0.0.0:56867 0.0.0.0:* 22278/tor
Tor version: 0.2.3.25 OS: Gentoo AMD64 (hardened profile)
See config file: User tor PIDFile /var/run/tor/tor.pid Log notice syslog DataDirectory /var/lib/tor/data SOCKSPort 0 ORPort 8890 DirPort 8891 Nickname XXXXX RelayBandwidthRate 5MB RelayBandwidthBurst 7MB ExitPolicy reject :
I tried to get DNSPort that seems likely to be the only Tor UDP port around, but the random port still appears.
I didn't manage to identify this port though I went through all tor manpage and tried to set almost all XXXPort directives to 0 at some point.
My "to be" Tor relay is behind a NAT, logs report successful setup: "Self-testing indicates your ORPort is reachable from the outside. Excellent. Publishing server descriptor." "Self-testing indicates your DirPort is reachable from the outside. Excellent."
