[smokeping-users] Use of EchoPingSMTP

[Cherrington Stuart]

Stephane,

Thanks for that. I had to set 'tos' to 0 as the echoping script expected
a value. My graphs are now working as expected.

Thanks,

Stuart.

On Linux (it seems to be te only Unix in that case), you need to be
root to set the precedence of an IP packet.

No, the "tos" option in your Smokeping configuration is (see
'smokeping -man Smokeping::probes::EchoPingHttp'). I advise *not* to
set it, it is of little use, anyway.

It warns you:

       You may need to be superuser to set some -p or -P  values
(precedence  on
       Linux, for instance).
