Why is netstat -n different between Solaris and Linux and how can I make it the same?

  • 772

When I run netstat -n on Solaris I get different results from netstat -n on Linux, even though according to the manual pages in Solaris and Linux the -n flag should do the same thing.

My question:

Please advise me how to run netstat in Linux so that I will get the same results as I get in Solaris.

EXAMPLE:

Solaris

 netstat -n | head-10

    Linux's netstat is from GNU's net tools, Solaris's isn't (Windows has its own too, so do the BSD's). You can install GNU on Solaris if you want GNU behavior.

  2. Linux netstat comes from net-tools which is not part of the GNU tools although licensed under the GPL.

    Solaris netstat originally comes from SVR4 netstat.

    Like most administrative commands, netstat is not standardized by POSIX so there is a large variation between the various implementations supported options and their output.

    net-tools netstat is then Linux specific so there is no way to install it on Solaris.
