CUCM Software Install/Upgrade FTP keeps failing, issues

[twhittle1]

Hi All,

I'm having issues with getting CUCM 11.5 to transfer a file from a ftp server and I think I must be missing something odvious. Can anyone assist?

I'm trying to send a new cop file for a phone to the CUCM to upgrade the firmware used.

Whenever I trying to transfer the file it fails saying:

"The remote file could not be accessed or fully downloaded. Please verify the file permissions or check status of the remote server."

I don't believe this is a FTP server issue because I've tried 2 different FTP servers and both can be access from another device (filezilla client on a windows box). So I think the FTP server is setup correctly.

Whenever I go to the Unified OS administration > Software Upgrades > Install/Upgrade and fill in all the relevant details it fails:

source: Remote File System

directory: \

server: x.x.x.x

username:

pw:

transfer protocol: ftp

It gets through to the next page, I can see all the COP files on the server.

Then when i select one and hit next it gives me the error:

The remote file could not be accessed or fully downloaded. Please verify the file permissions or check status of the remote server.

Any ideas??

Is there anything qwerky about this process i need to know?

Many Thanks,

Tom

OK after a bit of searching I've discovered the issue, it's a bug! - CSCuz93073

It's specific to CUCM11-5 and the workaround is to use SFTP rather than FTP.

I've tried it for a couple of files and I've not had any fail so far.
