Na "chybnom" stroji bolo vtedy asi este 256MB (P4/2.66) (uz je 1GB), 2. 
ping -f z 1GB stroja na 256MB stroj isiel OK, ale asi ten druhy ping 
-s35000 uz bol na "chybny" stroj vela.

1.
Preco to (okrem ineho?) vyriesilo aj vymena z netutils na iputils-ping ??

Dost mi to "neda spat".

2. Casto ping -f -sVELA testujem kable, switche, siet, nastavenia a HW 
vobec. A *nikdy* doteraz som sa s podobnou hlaskou nestretol.
Divne, nie?


Zatial diky aj za tuto Vasu odpo ...
Ak ma niekto este nejake napady/pripomienky - uvitam.
