I am running a server application (written in C), that is bound to my server on localhost address 127.0.0.1 and let it listen in first case on port 10000 and in second case on port 20000
When I run command I lsof | grep IP in last column is:
- localhost:webmin (LISTEN) (first case)
- localhost:20000 (LISTEN) (second case)
So instead of port 10000 there is webmin.
What does this mean? I found this.
It says that Webmin is a web-based interface for system administration for Unix. This doesn’t help me; why am I seeing webmin in my port list?
webmin is associated with port 10000. lsof is “deducing” that webmin is what is running. For instance, if your app was bound to port 3306, lsof would think it was MySQL.
See this Wikipedia link for a list of well-known ports.
