Solved: Re: Cisco IPS Error [errno="" 8] - Page 2

seanp · ‎10-08-2013

I have been attempting to setup the Cisco IPS app for Splunk 6. However I am getting the following error in the sdee_get.log:

INFO - Checking for exsisting SubscriptionID on host: <IPADDRESS>
INFO - No exsisting SubscriptionID for host: <IPADDRESS>
INFO - Attempting to connect to sensor: <IPADDRESS>
INFO - Successfully connected to: <IPADDRESS>
ERROR - Connecting to sensor - <IPADDRESS>: URLError: <urlopen error [Errno 8] _ssl.c:521: EOF occurred in violation of protocol>

where is the IP address of the IPS. Does anyone have any thoughts into what the error is? Any help is greatly appreciated

This looks a whole lot like https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/965371 which seems to be a bug in OpenSSL when attempting to do TLS version renegotiation. The bug was fixed in OpenSSL upstream and in Debian / Ubuntu.

But, Splunk ships with its own version of OpenSSL. In Splunk 6.0.0 it seems to be OpenSSL 1.0.1e, which is likely affected by this issue.

Ther launchpad link above suggests some (very very very hackish) workarounds like updating python standard library files. I would personally open a support case w/ Splunk and in the meanwhile perhaps downgrade to Splunk 5.0.5, which has an older OpenSSL. Or, you could install a 5.0.5 forwarder just for your IPS app...

By the way, Cisco IPS app is not compatible with 6.0 as of today, 10/15/2013.

Does this solution work?

I was starting get to that same conclusion but you are correct dwaddle. I had a co-worker who has OpenSSL 0.9.8y (Windows) run:

openssl s_client -connect

and connects no problem but when I run it using OpenSSL 1.0.1e it fails. I will contact tech support and see what they say.
