unix netstat command to filter output on foreign address

I want to show results of netstat for foreign address starting with 54. for ESTABLISHED TCP connections.

This is sample output I am looking for:

tcp 0 0 192.168.X.X:42436 54.X.X.70:80 ESTABLISHED -
tcp 0 0 192.168.X.X:51160 54.X.X.73:80 ESTABLISHED -

I have tried various commands but nothing comes close or I would list my attempts here, but they wouldn't be helpful.

Is this possible in a single command or do I need to create a script.

Solution

  • You can try with awk,

    netstat | awk '$5 ~ /^54/ && $6 ~ /ESTABLISHED/'
