Hi

I have a small problems with a small lot of Cisco 6500:

i use classical telnet access:

line vty 0 4
 exec-timeout 5 0
 password xxx
 login
 transport input telnet ssh
line vty 5 15
 exec-timeout 5 0
 password xxx
 login
 transport input telnet ssh

Cisco IOS Software, s72033_rp Software (s72033_rp-ADVENTERPRISEK9_WAN-M),
Version 12.2(33)SXJ5, RELEASE SOFTWARE (fc2)

No access list, no restriction.


we have only this information in debug:

TCP0: bad seg from 172.16.1.55 -- IDB not up: port 23 seq 2077473065 ack 0
rcvnxt 0 rcvwnd 4128 len 0

The problem does this product from certain IP source, not for all

a idea of this problems ?

thanks
Olivier
