Re: Disable telnet to ACS applliance 4.2 1113 SE

CSCsr56625            Bug Details

Telnet service is available once after getting a DHCP  address


Symptom:

When the 1113 appliance is running  4.2.0.124, configured for dhcp, and attached to network after  fully-started, the telnet port is open on appliance even with CSA  running.  The telnet port will remain open until someone exit a telnet  session from the appliance.

The telnet port will also open if the  ethernet port goes down/up.  It will also reopen it the appliance is  configured to use DHCP.


Conditions:


Workaround:
Apply   a ACL on the L3 interface to block port 23 to ACS



Re-image appliance with 4.2.0.124 and upgrade to 4.2.1 build 11.
Unplug the Ethernet cable from appliance.
Reboot the appliance via CLI.
Plug the Ethernet cable to appliance when appliance came up.
Do telnet into appliance.

Expected / Observed behavior:

You should not be able to telnet into the appliance after connecting the cable
