I have an asa5510 on 8.2.2. I have my logging configuration as below [code] I am not getting any syslog output to the syslog server. I'm using kiwi syslog server latest version. Have tried disabling/reenabling logging and changing inside host destinations. Is there another command needed

i want to configure asa 5510 to send syslog messages to syslog server which i placed in my inside interface. also if enableing syslog will inrease the cpu utilization or memory? the necessary configuration parts?
View 1 Replies View RelatedI've a problem with syslog logging on my Cisco ASA 5510 version 8.2(1). I need to:
- 1) log some ACL with warning level to log deny access.
- 2) log some ACL with informational level to log permit and deny access (notification level log only deny access and not permit access).
- 3) not log others ACL.
For 1), I configured the syslog server with warnings level and i enabled the logging rules with default level (syslog default level)
logging enable logging trap warnings logging host "interface" "host" . access-list "interface" extended permit ip any any log default.
For 2), I enabled the logging rules with specific level (informational).
access-list "interface" extended permit ip any any log 6 interval 300.
For 3), I disabled the logging rules.
access-list "interface" extended permit ip any any log disable
My problem is that the syslog logging level bypass the ACL logging level. Even if some ACL are configured with informational level, the ASA send only warnings logs to the syslog. I tried to configure the syslog default level to warnings, to remove the ACL and then put it back again with the specific logging level but I still have the problem.
I have recently setup Splunk to receive my syslog messages from my ASA 5510. In the past I used kiwi without observing this issue, but I needed more features than kiwi had available. Anyway, anytime I stop the splunk service my asa does not allow any outbound connections to be established.

View 9 Replies View RelatedAdd the ability to send syslog events to multiple syslog servers in the SA500 Series routers. I know the functionality is currently in the RV220W because we utilized it. It would be great if you could configure the syslog servers by event type as well. For example, being able to send the kernel events to syslog server A, and all other events to syslog server B.

We started getting the below syslog messages from one of our ASA5520 which was recently upgraded to 8.4(2). Any bugs on 8.4(2) that cause this or its simply the RAM failure?

How do you save the command output from the CLI to a file on flash?
With IOS, I would normally use a pipe command to redirect to tftp, but the ASA doesn't support this as far as I can tell. As a work around I was thinking I could save the output to flash and then tftp that file off the ASA.
We have an ASA 5540 failover bundle working in Active/Standby mode. On our active asa 5540 when the sh run command is issued it gets stuck and displays the output after more than 15-20 mins.. and it takes another 10-15 mins to get back to the prompt..
However on the standby asa 5540 if the sh run command is issued, it displays the ouput and comes back to the prompt (even though this also takes 2-3 seconds)
I have tried rebooting the active asa 5540.We are running asa version 8.2.2.
I'm having a bit trouble to limit the bandwidth on outgoing traffic with a Cisco ASA 5505.
In my case I want to limit the bandwidth to 31mbit/s up and down on the outside interface. but with my current configuration, just the download rate gets limited to 31mbit/s when I do a tptest. and the upload is around 40/50mbit.
Here is the policy configuration,
access-list outside_bw extended permit ip any any
class-map outside_bw

We use multiple ASA 5500/5580 cluster systems running 8.3 software versions.Actually we send all our FW syslog data to a SIEM appliance in a DMZ on a remote firewall (non-asa). Recently we suffered a strange incident while implementing a new SIEM collection station now situated in a dmz that is located on one of the ASA contexts. We redirected the syslog streams to the new client for one of the contexts on the ASA cluster that holds the new SIEM agent DMZ..since we did this and redirected the syslog we see double traffic and spoofing errors on that context
a/ the ASA keeps sending out the syslog traffic to the OLD SIEM agent server ip (there is however no trace of its ip in the config)
b/ the traffic leaving the interconnection interface towards the OLD SIEM agent gets a SPOOFING error on the traffic
c/ strangely the data gets also correctly forwarded to the new SIEM collection stations.
We started out with redirecting traffic on only one of the 5 contexts to the new environment and kept logging the others to the old system.I finally got out of the issue by reconfiguring al the other contexts to forward their syslog towards the same new server , since that moment we no longer have the double logging and spoofing error , all syslog traffic goes correctly to the new SIEM agent. It looked like some remenants of the old syslog config remainded on the asa event after deleting and introducing a new config line (we used the asdm to execute the action) as said either it kept the old config or it looked in the other context and "decided" to keep sending to the old server also mentioned in that syslog can find the behaviour in any buglists either way.
We have a firewall service environment where logging is handled with UDP at the moment. Recently we have noticed that some messages get lost on the way to the server (Since the server doesn't seem to be under huge stress from syslog traffic). We decided to try sending the syslog via TCP. You can imagine my surprise when I enabled the "logging host <interface name> <server ip> tcp/1470" on an ASA Security context and find out that all the connections through that firewall are now being blocked. Granted, I could have checked the command reference for this specific command but I never even thought of the possibility of a logging command being able to stop all traffic on a firewall.
The TCP syslog connection failing was caused by a mismatched TCP port on the server which got corrected quickly. Even though I could now view log messages from the firewall in question in real time, the only message logged was the blocking of new connections with the following syslog message: "%ASA-3-201008: Disallowing new connections."
Here start my questions:
- New connections are supposed to be blocked when the the TCP Syslog server are not reachable. How is it possible that I am seeing the TCP syslog sent to the server and the ASA Security Context is still blocking the traffic?
- I configured the "logging permit-host down" after I found the command and it supposedly should prevent the above problem/situation from happening. Yet after issuing this command on the Security Context in question, connections were still being blocked with the same syslog message. Why is this?
- Eventually I changed the logging back to UDP. This yet again caused no change to the situation. All the customer connections were still being blocked. Why is this?
- After all the above I removed all possible logging configurations from the Security Context. This had absolutely no effect on the situation either.
- As a last measure I changed to the system context of the ASA and totally removed the syslog interface from the Security Context. This also had absolutely no effect on the situation.
At the end I was forced to save the configuration on the ASAs Flash -memory, remove the Security Context, create the SC again, attach the interfaces again and load the configuration from the flash into the Security Context. This in the end corrected the problem. Seems to me this is some sort of bug since the syslog server was receiving the syslog messages from the SC but the ASA was still blocking all new connections. Even the command "logging permit-host down" command didn't wor or changing back to UDP.
It seems the Security Context in question just simply got stuck and continued blocking all connections even though in the end it didn't have ANY logging configurations on. Seems to me that this is quite a risky configuration if you are possibly facing cutting all traffic for hundreds of customers when the syslog connection is lost or the above situation happens and isn't corrected by any of the above measures we took (like the command "logging permit-host down" which is supposed to avoid this situation altogether).
Running ASDM V6.3 connecting to a couple of ASA5580's V8.2. After initial configuration everything seemed to work great, however, as of a few days ago I can no longer view statistical information. I can attach to the devices without a problem, view and edit all configuration information but the dashboard applets do not pull or display any statistical info. Resource, Interface, and Traffic status all time out with the error "Lost Connetion to Firewall". The syslog info is not display rather the error "Syslog Lost Connection". My first thought was a java issue on the client. I have ripped out and reinstalled even back-revisioned to no avail. I'm to the point where a dumpe of the management workstation is the next step. I'd like to avoid that extreme if possible.

I'm fine tuning some of our ASA logging config, and am having an issue with one particular syslog ID.The message is: syslog 106100: default-level informational (enabled)and the log settings are:
Syslog logging: enabled
Facility: 20
Timestamp logging: enabled
Standby logging: disabled
Debug-trace logging: disabled
[code]....
This ACE log entry is generated by explicit deny any any statements at the end of all the ACLs, e.g.access-list inside_access_in extended deny ip any any log interval 600 Based on the config, I would expect to see this being logged to the syslog server, but not to the local buffer, but am still seeing them locally in the buffer:
Feb 22 2012 10:58:20: %ASA-4-106100: access-list inside_access_in denied udp INSIDE/HOSTABC(52629) -> OUTSIDE/HOSTXXX(162) hit-cnt 5 300-second interval [0x3baecf1e, 0x0]
It also still shows these as level "warning", %ASA-4-106100, instead of the default %ASA-6-106100 I've tried removing and re-applying the config at different levels but it still reports in the buffer log as level "warning", %ASA-4-106100 This also doesnt affect every 106100 log that is generated. Most messages are generated at the correct level 6 severity but some seem to randomly log at level 4. There doesn't seem to be any pattern to this. The same access-list line can produce severity level 4 and 6 106100 messages.
Is it possible for a Cisco ASA 5580 to create Syslog entries when someone connects via HTTPS or SSH to it. I need to obtain information from Syslog when someone does this.
View 5 Replies View RelatedI'm trying to configure an ASA firewall (FW2) for syslog and tacacs and am experiencing strange behavior. Both the syslog and ACS server are on the inside of another firewall (CoreFW). Whenever a log message is generated on FW2 the request is dropped by CoreFW and message '%ASA-4-313004: Denied ICMP type=0, from laddr FW2 on interface outside-b2b to syslog01: no matching session' is displayed. The same thing occurs for tacacs.
It appears that the syslog and ACS requests are generating ICMP echo replies, which the core firewall drops since no session exists on a lower security interface. I have access lists configured on CoreFW to allow the syslog and tacacs requests.
FW2 is running asa825-k8.bin, CoreFW is asa824-k8.bin
I've just taken over a new network with a Cisco ASA5520. Everything is working fine, except I am being bombarded with 106001 alerts from a few internal hosts to one specific internal host. The description in general is "Inbound TCP connection denied from 10.1.0.1 to 10.1.0.5 - both of those are valid internal hosts and the TCP ports are also valid. I tried looking at the log and getting it me to tell me which rule was causing these alerts, but it just came back with 'It's not possible for these type of alerts'
- How is it possible for the ASA to even pick up on this when, in theory, the source host wouldn't be going near the ASA since it's on the same subnet?
- What might be causing this?
- How can I turn it off!! (I guess that'd be fixed by point 2)

I need to create a firewalled segment that not only separates hosts from general population, but also from each other. The solitary confinement of firewalled segments.I know that I could create a bunch of sub-interfaces, one for each host or group that needs to be isolated, but I'd really rather not have to do that if possible. 1) It could become a management nightmare between ACLs and sub-interfaces and 2) it's a waste of IP addresses.s there any way that I can create a bunch of separate VLANs behind the firewall and have them all terminate at the firewall, using a single firewall IP address for the gateway?
VLAN 1 - hosts 1.1.1.5 and 1.1.1.6VLAN 2 - hosts 1.1.1.7
Firewall DMZ Interface - 1.1.1.1VLAN 3 - hosts 1.1.1.8 and 1.1.1.9
This way, the hosts are isolated and can't talk to each other unless they're on the same VLAN.I'm working with an ASA 5510 running 8.2.4(4).
