Capture packet / ip logging

What is the best way to capture packets as well as display them for signatures.
I need to see the packets that cuase the ICMP hard DoS sig 2157 to fire. From the Cisco IDS Install and Configuration guide version 4.x it talks about enabling packet capture to true as well as Event action, but no clear instructions on which to use or if both need to be configured.

If you want to capture the packets that caused the signature to fire, then you must enable the "log" option as the EventAction in the signature. When the IDS detects an attack based on this signature, it creates an IP log.
There is also an "IP logging" feature in the IDS that is used to capture the packets for a duration of time. This capture is time or size (bytes) based and is not based on signature.

Ace 4710 can I capture packets on a Load Balancer

We have just implemented JD Edwards we have three servers front ended by ACE4710,most things are good, but I there are some reports(.CSV)generated by the system that cannot be viewed when going through the load balancer, but ok if going directly to the server. I have logged on as a user that is getting the problem, and it is ok for me! So it looks as if it could be a PC problem, but other people think it must be the LB. is there anything like Tethereal available within the ACE that I could use to capture packets.

Hi,
There isn't a tethereal built-in to the ACE, but you can capture packets.
You need to create an ACL to identify the interesting traffic and then use the capture command. This is documented in the command reference guide.
When you stop the capture copy the file from flash to disk0: ('copy capture disk0:') The copying converts the capture into a pcap format file readable with any sniffer tool like wireshark. You'll need to download the file from disk0: to a workstation to be able to run wireshark against it.

Unable to capture packets on ASA(ASDM)

Hi all,
We have site to site VPN connection to one of our client. From which we both are accessing our applications and other resources. Now client needs to acccess two of our internal server. So we have created Static NAT in our ASA. For one server they are accessing without any issues. But the other server they are not able to connect. Since its vpn tunnel we havent blocked any ports and its open to all traffic. But their side they have restricted and we need to see whether the packets hitting our ASA or not. Once we observes this, its easy for us to escalate them. I tried packet capture wizard in ASDM. But its not showing anything. Can anyone tell me how to capture packets realated to Static NAT. Please let me know if you want anyother details?
local 20.0.0.0/24 -->this will get natted to --->12.0.6.0/24 when going in for tunnel
we have created
static(outside,inside) 12.0.6.10 20.0.0.10 255.255.255.255 working
static(outside,inside) 12.0.6.11 20.0.0.11 255.255.255.255 not working, we need to check whether its hitting 12.0.6.11
Kindly advise...

Bala

Where are you trying to initiate the connection from?
If they are trying to initiate the connection towards your end, and the traffic doesn't reach your end, then there will be nothing on your ASA packet capture.
Please share what you have configured to capture the traffic?
To check if the traffic is reaching the inside interface, just configure ACL between source (real IP) and destination (remote IP), and apply the capture on the inside interface. This will confirm if the traffic is coming inbound towards the inside interface.
To check if the traffic is leaving the inside interface towards the host behind your ASA, configure ACL between source (remote IP), and destination (host real IP), and apply the capture on the inside interface. This will confirm if the traffic is leaving your ASA inside interface towards the host.

Capturing Application Error log from SXMB_Moni

Hi,
I wanted to capture the error information from Application error log from ECC sxmb_moni and forward that as email alert.
We have already alert configuration in place with alert category using standard variables. Was wondering if I have to capture application error log from sxmb_moni what would be steps involved. Please let me know if anybody has worked on this and appreciate your help on this.
Sample Error message from sxmb_moni of ECC system
MT_Fault
Error in Application System
Detailed Information

Thanks

Hi Selvam,
As the exception is raised in ECC system, alert cannot be trigger, alert will get trigger when there is a error in PI system. To raise a email, write additional code in ECC to trigger the e-mail with proper error content

Belle: No WLAN and Packet Data log.Filter options ...

In Nokia N8, with Symbian Anna, WLAN and Packet Data logging wasn't possible, even though there were options in the log filtering settings.
See below:
http://i44.tinypic.com/9kxbfa.png
After updating to Belle, log isn't still working, and both WLAN and Packet Data options were removed from filter options.
http://tinypic.com/r/6dxwgg/5
Will it be implemented in a further time?
Best Regards

Hi,
quick update on this one as we now have a FAQ online.
Q: How can I get a WLAN/Wifi and packet data filter with Nokia Belle?
A: There is no data filter included in Nokia Belle by default, but you can download specific apps from Nokia Store.

Clarification on packet data log

I understand the Packet Data logs can remember upto last 30 days. What I don't
understand is are they rotating logs or do they reset to zero every 30 days. To take
an example: if I use exactly 1MB every day and my log setting is set to 30 days. After
40 days ...
- with rotating logs, I'll see 30 MB usage
- with reset-to-zero logs, I'll see 10 MB usage
So which one is it ? I'm using C5-00 on 032.010 if that matters. Thanks.

Can't view all captured packets.

Hello,
Is there any command which allows to change number of displayed captured packets?
I have a following capture setup:
capture SFTP_TEST type raw-data access-list SFTP_TEST buffer 200000 interface inside circular-buffer [Capturing - 199102 bytes]
when I issue command show capture SFTP_TEST I get:
1676543 packets captured
1...
2...
and so on
157 packets shown.
So far I have tried:
show capture SFTP_TEST count 10000
same result (only 157 are shown)
same when I try
show capture SFTP_TEST count 10
(always displays magic number 157)
I have a very similar capture setup on another firewall and I can view all packets without any problems.
Any help will be much appreciated.
Regards
Mariusz

Hi Jouni,
Thanks for replying.
I though the same, but the confusing bit was different number of packets captured and number of packets displayed.
Looks like the “packet captured” shows total number of packets processed by the defined capture rather than packets in the buffer so it makes sense what you said.
I have reconfigured this with the maximum 33554432 buffer and I’ll post the outcome in few days.

Capturing packets from two server programs in single solaris box

Hi,
Greetings.
I observe that snoop is not capturing packets exchanged between two server process which are running in a same solaris machine.
Are there any options with snoop, so that it is possible to capture the
packets between two server processes in a single machine ?
Thanks in advance.
BR, RK

Snoop? No. Packets to the same machine never reach the DLPI layer which is where snoop is looking.
There are some 'dtrace' scripts on Solaris 10 that attempt to view the contents as they go within the machine. They should work with most interfaces.
I don't know of any good solution for Solaris 9.

N95 Packet Data log duration won't clear

I would like to know if anyone else has experienced a fault that I have with my N95 8G running the latest version of software.
The fault is around the Packet Data log.
I want to be able to keep tabs on my daily data usage, so have set the log duration to 1 day. When I check the packet data counters the following day, they have not reset. I have left the counter running for 7 days now and they still haven't reset.
Maybe I don't understand this feature, but I was expecting the counters to reset after 1 day.
Nokia support have sent out their standard 'we have no idea wants wrong' email requesting me to return the phone back to factory setting and loose all my data, which I'm reluctant to do.
Cheers,
Paul

The "keep logs for" feature does not affect the counters.
All it does is keep individual events for the specified duration.
Enter the "logs" application and then scroll right. You'll see a list of logged events (calls, messages in/out, packet data usage etc). THESE are the entries kept for one day with your settings.

Trouble Capturing Packets with Embedded Packet Capture

Hi All,
I am trying to capture packets originating from a server to a host device across three switches:
server -- 6513 -- 3850 -- 3550 -- host A
I am doing a ping from the server to host A. The packet capture is being done on the 3850. This is my configuration:
access-list 100 permit icmp host 192.168.101.6 host 192.168.100.188
access-list 100 permit icmp host 192.168.100.188 host 192.168.101.6
end
monitor capture buffer TRACE
monitor capture buffer TRACE filter access-list 100
monitor capture point ip cef CAP g1/1/1 both
montior capture point associate CAP TRACE
monitor capture point start CAP
I then issue a ping from the server to host A. Interface g1/1/1 is where the 6513 connects to the 3850. When I issue a show monitor capture buffer all parameters, there are no packets. If I remove the filter from the buffer I still do not see the packets.
Does anyone have any advice here?

I tried recreating the packet capture with no access-list filtering.

Resend captured packets from cisco ios? (tcpreplay w/o WireShark)

Hello again,
As the title of the thread implies, is there a way to replay captured packets (as in a pcap file from the EPC protocol) from cisco ios? I am trying a work around by calling it from a connected computer, but I can't launch tcpreplay dynamically from an EEM script (mainly because I can't target the host OS from the EEM scope).
Basically I am capturing packets in order to delay them until some arbitrary time determined by another (or even the same) EEM script. Is there a function I don't know about that I can call to put previously captured packets (stored in a pcap file) directly back on the bus as if nothing happened?
Thanks in advance,
-Heath

You can't replay packets right now. The upcoming onePK APIs will allow you to do this, however. If you want to call tcpreplay from your EEM policy, you could send a trap to the host, which triggers the excution, or use the Remote Command Shell policy from http://www.cisco.com/go/easy to telnet/SSH to the host from the device to run the command.

Regarding capturing VF01 ERROR logs in a background job

Hi ,
We are running a background job that calls transaction VF01 via BDC .
CALL TRANSACTION 'VF01' USING   bdcdata
                          MODE    S
                          UPDATE N
                          MESSAGES INTO gt_messtab.
In some cases billing documents will not be generated. In such cases systems will throw message "Check the log "
After which we can check the error messages via Menu Edit>logs.
This error messages (stored in XVBFS internal table) need to captured in the job log i.e custom programme.
Unfortunately i could not found any user exits/BADIs that can help me in capturing message.
Can you please help me how can i solve this issue?
Thanks in advance
Manoj

Hi Manoj,
I had a similar problem.
I solved it selecting from VBSK the last record of the user regarding elaboration of invoices, and then calling f.m. 'VBSK_ALV_DISPLAY'.
Otherwise you could call directly transaction "V.21"
Hope this could help you

Help! Batch Capture Changes My Logged Clips' Media Start & Media End

I'd be very grateful for any help on this.
I log a tape with about 40 clips ranging from 30 seconds to 4 minutes. I select the clips and start a batch capture. Everything appears to be capturing normally and I receive no error messages or dropped frame warnings - after my last clip is captured I get a "Successfully Captured" message.
However, as soon as I click "Finished," all of my clip media start's, media end's, and durations in the log window arbitrarily change to weird times. All my media start points are 26 frames too early (I've tripple-checked that "Add Handles" is indeed deactivated), and the media end points make no sense at all.
A clip that was once 44 seconds long is now only 12 seconds long, the media end point moved a whopping 34:03 too early. Another clip will become 2 seconds longer, the media start point still shifted back 26 frames, but with the media end now 31 frames too late. Checking the original files on my drive confirms that only these weird, unusable segments are what has been captured.
What complicates things is that I just discovered today that if I capture locally to my internal hard disk, the clips capture normally (the times remain unchanged). But if I set my capture scratch to my external hard drive (a LaCie F800 2-TB RAID-5 using Firewire-800), that's when the clips start changing themselves. I ran disk utility and found no errors on the drive, and have never had a problem with it or any part of my configuration until the last month or so... the only changes to my system being the regular use of Software Update.
On top of that, my colleague is experiencing a similar problem with batch capture changing his clip times, even though he is using a different computer (single-processor G5), a different video deck (Sony DHR-1000), and a different storage medium (Apple Xserve RAID).
So my question is: What is happening! The only thing I can think of is that perhaps some update has a bug - but I can't find anyone with a similar problem online.
Any help on this would be extremely appreciated! Thank you in advance for your advice.
Dual 2.3GHz PowerPC G5 Mac OS X (10.4.4) Deck: JVC CU-VH1 / Storage: LaCie F800 2-TB RAID-5
Dual 2.3GHz PowerPC G5 Mac OS X (10.4.4)

Here's an update on this. Both my colleague and I have confirmed that if we capture to an internal or external drive that is not a RAID FCPro batch captures just fine.
But, if the drive we are capturing to is a RAID (in my case a LaCie Biggest F800 and his case an Apple Xserve), then we get dropped frame reports and/or clip in's and out's changing after the batch capture is complete.
We even tried reformatting one of the xServe's and rebuilding it as non-journaled, it didn't solve the problem.
It seems impossible that we're the only ones to be experiencing this problem... does anybody have any help or suggestions!?

Capturing Batch Input Log without keeping BDC session

Hi all -
Would like to capture the Batch Input log and keep it persistent in some manner (for example using an application log) without keeping the corresponding BDC session. The reason for this is that any manual corrections to data interfaces through BDC sessions MUST be logged indefinitely for audit purposes. The actual BDC sessions are HUGE and therefore precludes saving the entire BDC session. My thoughts are user-exit'ing in BDC session either as a Batch Input Log is being created or when a Session is being deleted (NOTE: running ECC 6.0 which has new enhancement concept permitting extremely flexible user-exit'ing so exit points are NOT an issue and repair/core mode not required). Anyone see any flaws with this approach or can recommend perhaps a simpler or standard approach so that Batch Input Logs are retained indefinitely whereas the Session is deleted?
Many thanks,
Pat

Hi Pat,
Why dont you try archiving?
For archiving, archive object BDCLOGPROD can be used. if archived, then you can read the archived logs using program RSBDC_ARCHREAD (also accessible from SARA->Read).
See some notes if it is helpful:
147354, 18319, 24438, 18307
Also have a look at the Data Management Guide available at service.sap.com/data-archiving.
Hope this helps,
