lsof command for monitoring
In Linux operating system lsof is powerfull tool for find out various kinds of status and list of open files from all over the system, there are various options provided in lsof which helps a lot to a Linux admin in his/her day to day life. In this post I am just trying to capture various lsof examples that I am using most of times in my present setup
1. Open TCP and UDP ports with running protocols
Want to see open Ports, both TCP and UDP ports. In this command output Port numbers will not display
[root@server ~]# lsof -i
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME

avahi-dae 7347 avahi 16u IPv6 13272 UDP *:filenet-rpc
sshd 7528 root 3u IPv6 15320 TCP 192.168.1.110:ssh->192.168.1.3:49232 (ESTABLISHED)
2. Open ports with Port numbers
This is same command, but it just display Port numbers as well instead of protocol
[root@server ~]# lsof -i -P
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
portmap 6805 rpc 3u IPv4 12002 UDP *:111
portmap 6805 rpc 4u IPv4 12010 TCP *:111 (LISTEN)
rpc.statd 6844 root 3u IPv4 12088 UDP *:663
rpc.statd 6844 root 6u IPv4 12072 UDP *:660
rpc.statd 6844 root 7u IPv4 12132 TCP *:666 (LISTEN)

python 7091 root 4u IPv4 12686 TCP server:2207 (LISTEN)
sshd 7121 root 3u IPv6 12743 TCP *:22 (LISTEN)

cupsd 7161 root 5u IPv4 12815 UDP *:631
sendmail 7204 root 4u IPv4 12947 TCP server:25 (LISTEN)
avahi-dae 7347 avahi 13u IPv4 13269 UDP *:5353
avahi-dae 7347 avahi 14u IPv6 13270 UDP *:5353
avahi-dae 7347 avahi 15u IPv4 13271 UDP *:32768
avahi-dae 7347 avahi 16u IPv6 13272 UDP *:32769
sshd 7528 root 3u IPv6 15320 TCP 192.168.1.110:22->192.168.1.3:49232 (ESTABLISHED)
3. Open Ports numbers with their process Id numbers
Above commands will display Process id of backend process that cause this port up, but in below command will also display parent process IDs of process. Some time we also need to know parent process of process which cause this port up.
[root@server ~]# lsof -i -P +R
COMMAND PID PPID USER FD TYPE DEVICE SIZE NODE NAME
portmap 6805 1 rpc 3u IPv4 12002 UDP *:111
portmap 6805 1 rpc 4u IPv4 12010 TCP *:111 (LISTEN)
rpc.statd 6844 1 root 3u IPv4 12088 UDP *:663
rpc.statd 6844 1 root 6u IPv4 12072 UDP *:660
rpc.statd 6844 1 root 7u IPv4 12132 TCP *:666 (LISTEN)
hpiod 7086 1 root 0u IPv4 12657 TCP server:2208 (LISTEN)
python 7091 1 root 4u IPv4 12686 TCP server:2207 (LISTEN)
sshd 7121 1 root 3u IPv6 12743 TCP *:22 (LISTEN)

avahi-dae 7347 1 avahi 14u IPv6 13270 UDP *:5353
avahi-dae 7347 1 avahi 15u IPv4 13271 UDP *:32768
avahi-dae 7347 1 avahi 16u IPv6 13272 UDP *:32769

4. Port working for TCP only
Above commands are used for TCP and UDP ports, but in case we only want to display TCP or UDP ports. Below command will able to display it.
[root@server ~]# lsof -itcp
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
portmap 6805 rpc 4u IPv4 12010 TCP *:sunrpc (LISTEN)
rpc.statd 6844 root 7u IPv4 12132 TCP *:mdqs (LISTEN)

rpc.mount 7813 root 7u IPv4 18896 TCP *:784 (LISTEN)
ypserv 7855 root 6u IPv4 19065 TCP *:itm-mcell-s (LISTEN)
5. Display specific ports
Above commands will cover all ports but sometime we just need to know status of only one port like mentioned in below command.
[root@server ~]# lsof -i :25
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
sendmail 7204 root 4u IPv4 12947 TCP server:smtp (LISTEN)
6. Display range of ports
In some requirements, we need to know status of some port range like 1-100 ports. we can use below commands for this
[root@client ~]# lsof -i :1-100
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
sshd 7125 root 3u IPv6 12891 TCP *:ssh (LISTEN)
sendmail 7196 root 4u IPv4 13081 TCP server:smtp (LISTEN)
