[CentOS] SSH on port 6010

hi evryone, the command

netstat -patn | grep LISTEN

shows the next line

tcp        0      0 ::1:6010                    :::*
     LISTEN      5195/1

and the command

ps ax|grep 5195

shows

5195 ?        Ss     0:00 sshd: root at pts/1

i was thinking if this is normal when i connect to the server through
ssh, but in another server centos doesn't appear a similar line in the
netstat command

thanks for any explication/orientation
