Packet dump on Cisco

Finally found a way to dump packets on a Cisco Router for tracing.

Router (config)# logging buffered 15000 (this creates a large enough buffer to look at locally on the router,or you can configure the router to log the ACL matches to a Syslog Server).
Router (config)# access-list 101 permit tcp any gt 0 any gt 0 log
Router (config)# access-list 101 permit udp any gt 0 any gt 0 log
Router (config)# access-list 101 permit icmp any any
Router (config)# access-list 101 permit ip any any log (this entry is a “catch-all”)
Router (config)# interface interfaceRouter (config-if)# ip access-group 101 in

Look at the log by using the show log command from the exec prompt. You should see IP addresses (source and destination), along with the used TCP or UDP ports (in parentheses):

One of the issues with the above is rate limiting on access-list’s, another way to trace packets is with debug, while this can be dangous, it can be usefull to. No need to use log in the access list.

config t
!disable CEF
no ip cef
int f0/1
!disable route cache
no ip route-cache
end
debug ip packet detail 101

Teksumo flying wing

Ordered a new flying wing for myself, the Teksumo looks like it will be a good versatile wing, a bit cheaper than the Swift II, and easier to handle than the Ritewing Zephyr II.

Kerberos Auth in squid

Look like i’ll need to check out how to use kerberos auth in squid rather than ntlm

[2012/03/06 15:25:47.488709, 1] libsmb/ntlmssp.c:342(ntlmssp_update)
got NTLMSSP command 3, expected 1

“The “3” and “1” have been explained as the difference between NTLM vs Kerberos. 
As far as I can tell “3” means Kerberos is being used. “1” is NTLM. 
The ntlm_auth helper only checks NTLM and the squid_kerb_auth helper is needed instead for Kerberos. 
Looks to me like the client is broken and using Kerberos when offered NTLM as the only available auth option. “

Nice Article about Kerberos may help

E-Maxx Body

Kids designed and painted a new ’72 Chevy body for the E-Maxx, I’m happy with the results. Blend from blue to green turned out ok, red cross on the roof reminds me of the Dukes of Hazzard, lol.
