i was just wondering, maybe someone else is able to shed light on the issue. scenario: 1 cisco 677 with CBOS 2.3.0 a buncha PC's equipped with various OS'es and a TCP/IP stack.Ping the cisco router with a packet exactly 65500 bytes in size, and it will die. Well known and documented bug afaik.
But - what are the differences in the ping command in the following OS'es ? win95: router doesn't crash win98: router crashes winNT: router doesn't crash win2K: router crashes Linux: router doesn't crash, tried with hping2, no effect either. *BSD : router doesn't crashas you can see the bug can only be triggered by the ping command from win2k. So now i ask, in my usual novice way.
Whats the difference? why is it there? does the ping command in 98/2k send 'illegal' data along with the packets? or are the others misbehaving? I have no idea.. maybe you do.
