I have configured dhcpd in an ASA 5505 and every thing is working. I am testing it to give me a warning when the address pool is about to be finished or it is empty. But don't konw how to do it. if I run the "debug dhcpd packet", i get that the address pool is empty.
View 3 RepliesATT notified my company we have a virus infected pc on one our networks which sits behind a Cisco ASA 5505 running 7.2(4). The set up is a basic inside/outside NAT configuration. They gave us the destination ip address and port which the our pc is contacting. I have been tasked to track down the infected pc. I created the following access-list and applied to the inside interface:
access-list VIRUS extended permit TCP ANY host x.x.x.x EQ YYYYY log debugging interval 600 access-group VIRUS in interface inside
I enable logging to the console whose output did not list the IP address of the infected pc, only the ip address of the DNS servers we were using. I then used the following capture commands to try locate the internal ip address of the infected pc:
capture in-cap interface inside access-list VIRUS-CAP buffer 1000000 packet 1522 capture in-cap access-list VIRUS-CAP interface inside
Neither step worked and the resulting console output overwhelmed the firewall in a very short period of time. Before attempting this task again, I would like to know if I am going about this the right way or if there is a better methodology?
I'm encountering what I think is an issue on logging system on FW ASA 5520 - Asa Version 8.4(2), ASDM version 6.4(5). When I disabled the logging inside a rule from ASDM, or from console with the "log disable" option inside ACL, If I check in ASDM logging real time window I continue to see all the entry related to disabled rules. This is a correct behaviour about ASA logging ? How I can "hide" the entry related to disabled rules (this is what I need for troubleshooting purposes) ?

View 2 Replies View RelatedI have a situation in which I want to log a specific message (informational - 6 level), but don't want to enable informational logging and get all the messages that come with it. Is there a feature in IOS, 3560 12.2(25r)SEE4, similar to the 'logging lists' feature on the ASA that allows you to specify logs that you want to capture without having to change your logging level? I didn't want to have to write an EEM applet for this, but if that's the only way, I'd consider it.

Is it possible to configure the ASA to:

and
log syslog critical to a different host
It seems that the ASA allows you to only specify 1 logging severity level for all syslog hosts..
