understanding lsof -i output with web browsing
I don't understand some output lsof command.
I try to run lsof -i on my home machine(debian linux) and what i obtain (showed one line; my browser chromium was running)
# lsof -i
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
chromium- 2379 brenta 70u IPv4 45006 0t0 TCP brenta.local:44023->stackoverflow.com:www (ESTABLISHED)
the man page explains about column NAME:
the local and remote Internet addresses of a network file;
the local host name or IP number is followed by a colon (':'), the port,
``->'', and the two-part remote address.
I try to run this comman on the other machine (linux mint):
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
firefox 2778 brenta 59u IPv4 68476917 0t0 TCP NOT_MY_HOST:39812->stackoverflow.com:http (ESTABLISHED)
Why column NAME contains not my host, but the other machine in local network?
linux networking lsof
