When I used the netstat -a command to check for active connections, I encountered this entry under active unix domains sockets(servers and established)
Proto Refcnt Flags Type State I-node Path
unix 2 [ ] DGRAM 32773 @@@@2@@��@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
I am new to networking. What is implied by this?
I also had that path in my netstat output.
As it turns out it apparently belongs to uml_switch, which appears to be a program to assist with network access from user-mode Linux.
The program is being called with the following cmdline:
/usr/bin/uml_switch -unix /var/run/uml-utilities/uml_switch.ctl
I'm not sure if that's actually something to be concerned about. Howewver I did build user-mode Linux and I can imagine that simply to be a bug that not many people encountered.
I simply used:
sudo lsof | grep INODE
with INODE being the value associated to that string that has been encountered with netstat.
That being said if you installed it via apt, you can probably remove it with
sudo apt remove uml-utilities
