virtual void stubIcmp::Close ( void  )

inlinevirtual

Reimplemented from Icmp.

int Icmp::ipHops ( int  ttl )

protectedinherited

Translate TTL to a hop distance

Parameters

ttl	negative : n > 33
ttl	n(0...32) : 32 >= n >= 1
ttl	n(33...62) : 32 >= n >= 1
ttl	n(63...64) : 2 >= n >= 1
ttl	n(65...128) : 64 >= n >= 1
ttl	n(129...192) : 64 >= n >= 1
ttl	n(193...) : n < 255

Bug:

BUG? ttl<0 can produce high hop values

BUG? ttl>255 can produce zero or negative hop values
