Subject: 20. How can I prevent incoming telnet console connections to my unit?

In software release 4.4 and later, Ascend has added a 'telnet password' to the code; when set, it is the first thing prompted for when a telnet session is established.

If you want to drop all incoming telnet sessions from being established, you can create an incoming data filter and apply it to your connection profile. An example would be:

In filter 01...Valid=Yes
In filter 01...Type=IP
In filter 02...Ip...Forward=No
In filter 02...Ip...Protocol=6
In filter 01...Ip...Dst Mask=255.255.255.255
In filter 01...Ip...Dst Adrs=10.10.10.10
In filter 02...Ip...Dst Port Cmp=Eql
In filter 02...Ip...Dst Port #=23
[replace "10.10.10.10" with your P-50's IP address]

This filter should be applied in conjunction with other filters that permit the kind of data you wish to pass through (e.g., everything else). Otherwise you won't see anything much at all... :)
