what/where is ss tool ?

what/where is ss tool ?

[Maciej Soltysiak]

Hi,

Reading help about tcp diagnostics we can read:

"Support for TCP socket monitoring interface used by native Linux
tools such as ss."

I have not heard of this tool yet, where can i fetch it from?
I tried using google but with no good results.

Regards,
Maciej

It comes with iproute2 (developer.osdl.org/dev/iproute2).

Thanks Patrick!

Maybe we could add a line to the help so people, like me, that were
not aware that ss exists.
AFAICS ss appeared not so long ago, I think many distributions are
still using versions that do not have ss.
Or I may be wrong.

Regards,
Maciej

Add also "if you wish to view IPv6 addresses (Local/Peer Address) with ss,
IPv6 support must be built into the kernel (not as a module)."

Hi Dave,

please apply this patch which gives users a pointer where
to find the ss tool and adds an explanation about TCPDIAG
and IPV6.

Patrick

Patrick, I caught one minor typo.  "you need to built this" should read, "you need to *build* this".
