Cisco SourceFire or Firesight Estreamer Woe


Pertaining back to the same discussion some time back , here is something i did to resolve the connection error .

Typical Java error i am facing and forever seeing this is

" connection closed by remote host "

Thing to check back ,

a) open up defense center or Virtual Defense with admin right

b)  Click on Monitoring -> Syslog

c) type your ip address of the SC that talking to VD or DC

d) Spot the error

Nov 26 2015 10:22:42 Sourcefire3D SF-IMS[16873]: [16873] EventStreamer child(x.x.x.x):ConnectionHandler [ERROR] Certificate Common Name x.x.x.x does not match remote host: y.y.y.y .  It was issued to a different client.

This error due to ip address translation from FW to DC , get your Network or FW team to resolve it .

However ,  i speed-up the process by using hostname and instead of using IP address as my PKCS cert .

So my cert file name now in user/agent/sourcefire/<myschost>.pkcs

then i hit another error.

Nov 26 2015 10:33:22 Sourcefire3D SF-IMS[18379]: [18379] EventStreamer child(myschost):ConnectionHandler [INFO] DNS lookup failure for myschost: Invalid Argument

Nov 26 2015 10:33:12 Sourcefire3D SF-IMS[18369]: [18369] EventStreamer child(myschost):ConnectionHandler [ERROR] Can not resolve remote host: myschost for issued certificate (err:SUCCESS)

To resolve this ,

add an entry with the valid ip address in  /etc/hosts in the Sourcefire3D appliance or server (need root access though) and do a trial ping back to "myschost" to confirm connection.

Hope this help
