Message-ID: <OF10009C95.242A78D6-ON48256D6E.000E00AB@com.au> From: tcleary2 at csc.com.au (tcleary2@....com.au) Subject: Re: Cisco IOS Denial of Service that affects most Cisco IOS routers- requires power cycle to recover Guys, >So... has anyone been able to verify that the problem occurs when the TTL >expires without the packet being addressed to the router? Or is it a >requirement that the evil packet be addressed to the router? As far as we know, the TTL has to go to 1/0 on the target IP address. Haven't been able to get the effect on a transit packet.
