We have so many Cisco ASA 5505 and 5010 and we are only using them for Lan2Lan Ipsec tunnel.
For some reason, one of our ASA has its flash full of files that i don't recognize.
Also the other day, I tried to telnet to ASA from the LAN side, and my password was rejected for some reason, it keeps saying connection closed by host.

This is what I get when I show flash:

asa5505-RDW# sh flash
Initializing disk0: cache, please wait........Done.

What are these all these PortForwarder.po, linux.pkg.

I never configure any anyconnect or anything for linux connection.

Do you think it's possible someone has hacked in to my ASA?

FYI, all internet ports are open on the ADSL router to the ASA.

i would've thought this is save as we have proper ACL, allowing only access for ipsec tunnels..

let me know what you think..

thanks in advance

Those are files that are on the router to facilitate the remote instalation of the AnyConnect VPN client.  They came with the router, no need to worry.

This files is the ASA's files. If you don't use anyconnect, just delete it. You can use only asdm and boot flash files.

And what about the telnet. Check yours AAA settings and telnet settings in config.

My understanding, if you never configure any connect the flash should still be clear.

I did sh run on 5 of the rest asas we have and they all show the same:

Perth-ASA5505# sh flash
Initializing disk0: cache, please wait....Done.

the telnet issue, is just another weird thing, everytime tunnels are dropped, I cannot telnet to the box from LAN site and this doesn't make sense.

I'll keep question open for now, will try to run syslog server or maybe I can catch some interesting log..

Are you using ASDM for configuring? ASDM can wrote some files, also may be you vendor is made a pre-configuration?
