To show all networking related to a given port:

lsof -iTCP -i :port
lsof -i :22

To show connections to a specific host, use @host

lsof [email protected]

Show connections based on the host and the port using @host:port lsof [email protected]:22

grepping for LISTEN shows what ports your system is waiting for connections on:

lsof -i| grep LISTEN

Show what a given user has open using -u:

lsof -u daniel

See what files and network connections a command is using with -c

lsof -c syslog-ng

The -p switch lets you see what a given process ID has open, which is good for learning more about unknown processes:

lsof -p 10075

The -t option returns just a PID

lsof -t -c Mail

Using the -t and -c options together you can HUP processes

kill -HUP $(lsof -t -c sshd)

You can also use the -t with -u to kill everything a user has open

kill -9 $(lsof -t -u daniel)

Retkarčiais tenka rekursiškai visiems failams ir direktorijos pakeisti rašymo / skaitymo teises, tam puikiai tinka find + chmod tandemas 🙂

Keičiam “chmod” katalogams:

find . -name '*' -type d -exec chmod 0755 {} \;

Keičiam “chmod” failams:

find . -type f -exec chmod 0644 {} \;

Pasižiūrim visas naudojamas repositorijas:
