Socket monitoring by watching receive and send queue every 5 seconds

$ while true; do netstat -tn; sleep 5; clear; done

Result:

This is to emulate combination of watch and ss in Solaris, more or less same result

$ watch -n 5 ss -t

For ssh-server and client there exists SUNWsshcu, SUNWsshdr, SUNWsshdu, and SUNWsshr. So we can install them instead of OpenSSH. But there is bug that will show UTF-8 error, so we need to install also SUNWuiu8 for iconv as workaround.

gunzip -c SUNWxxx.tar.gz | tar -xvf -
or
unzip -q SUNWxxx.zip


2. install in the directory that has SUNWxxx directory in it

pkgadd -d $PWD

It will list installable package found within (including SUNWxxx)
