Hi, I was just running nmap on my Debian 2.2 box and noticed the following output:
[EMAIL PROTECTED] /home/freedman]# nmap -sT osprey Starting nmap V. 2.12 by Fyodor ([EMAIL PROTECTED], www.insecure.org/nmap/) Interesting ports on osprey (192.168.0.1): Port State Protocol Service 22 open tcp ssh 25 open tcp smtp 53 open tcp domain 3086 open tcp sj3 Nmap run completed -- 1 IP address (1 host up) scanned in 0 seconds The sj3 service on port 3086 flicked into existence on this one scan but was never in existence before or after. I didn't even know what it was! A Google search showed it to be Kanji Character output service, or something similar. I never explicitly installed or configured this, and have a relatively plain-vanilla machine. Is this cause for concern? Does it suggest my machine was compromised? What should I investigate further? Suggestions appreciated and gratefully received. Thanks so much, Daniel
