ASA 5520 AIP SSM20 ftp upgrade error


I am trying to upgrade the AIP SSM 20 to IPS-K9-6.2-4-E4.pkg.

The problem is that this error as below comes:-

Error: execUpgradeSoftware : Connect failed

I can confirm the following:-

1) Ping from FTP server to sensor and vice versa is OK

2) FTP server works OK, as i am able to upload/download files from other clients

3) Command given is as upgrade ftp://anonymous@

4) I also created another user in FTP server, tested but same results

5) The FTP server listens on port 21 and does not gets any request.

6) Current image is a bit old i.e. 6.0(4)E2

Some information from show version is as:-

Using 1023815680 out of 2093600768 bytes of available memory (48% usage)

system is using 17.7M out of 29.0M bytes of available disk space (61% usage)

application-data is using 39.3M out of 166.8M bytes of available disk space (25% usage)

boot is using 38.4M out of 68.6M bytes of available disk space (59% usage)

Image that i am trying to upload i.e. IPS-K9-6.2-4-E4.pkg. is about 28.6 MB in size, could the issue be related to the disk size (show in bold above)?

Please help

Thanks in advance.

ASA 5520 AIP SSM20 ftp upgrade error

I remember a problem when trying to download a file from the root directory. The moment I placed the file into a subdirectory, everything worked. Perhaps you are facing the same problem?
