We have 4 Cisco ASA-SSM-AIP modules that need the new signature set applied. We are getting an error trying to ftp the upgrade to the console of these devices. "Error: execUpgradeSoftware : Received only partial file: 131072 bytes". We have downloaded the S363 version multiple times to no avail. Are we missing something? It appears as if the download is corrupt but we have verified the file size with the original. We have tried the upgrade on all four and it fails on each one.

Verify your downloaded file using a MD5 checker once you've download it and don't merely rely on comparing the byte size. Many freeware MD5 checkers are available on google. Sometimes proxies cache the file and you keep downloading the same file again and again (even tough you are re-downloading). Sometimes this can be evaded by changing the filename of the downloaded file (then rename it back).
Also try to use a different FTP server to rule out any issues there (FileZilla is a nice and free one).
Hi I have downloaded the latest signature file (.pkg) format as my IPS sensors do not have access to the Internet...
Can someone explain where in SDM I need to go in order to update the signatures? I have seen within the Configuration tab > IPS > and at the bottom of the left hand menu there is "Update Sensor" and this allows you to direct the gui to a file located on the client or on an FTP server...
Is this "update" referring to a signature update or a software update?
