If anyone out there uses the Cisco 4200 series IDS appliances running rev 4.0, get ready for the stupidity - again!!
There is a new way to get signature updates via FTP. The only problem is that it is broken. I opened a TAC with them and they have acknowledged the issue but they haven't provided a work around. Well today is your lucky day. If you use SCP via SSH, the update system will work. Those who are using these IDS appliances will know what I'm talking about. I discovered this by pure accident but hey, it works!
Once again, Cisco makin me proud to be an enterprise customer.
Hope this helps out!
