Cannot get files via FTP

[sra]

I have a 2611XM with 12.3(5b) IOS, running image c2600-ipbase-mz.123-5b.bin. I want tup update the IOS via FTP but it hangs. The weird thing I can upload files fine, I could upload my current image and config, just the download fails:

gwext2#copy ftp: flash:

Address or name of remote host []? x.x.x.x

Source filename []? cisco/c2600-i-mz.123-6a.bin

Destination filename [cisco/c2600-i-mz.123-6a.bin]? c2600-i-mz.123-6a.bin

Here is where it hangs. On the FTP server I dont even see the connection, most of the time. Somethimes I see what's in the attached file

Any idea what's going on ? FTP works fine from another box (not the router), upload and download, so the FTP server is fine. Just the router wont download.

Thanks,

Stefan,

I had the exact same problem when pushing a 40Mb IOS to a 6509/Sup720. Try another FTP program like BulletProof. It should work like a champ.

Hmm.. I'll be honest, I never even knew you could use FTP. I can't get it working either for the past couple minutes I've been trying...

Why not just use TFTP? Much easier and I rarely have it not work... Seems to be the preferred way of doing it also from what I can tell from Cisco. Both Solarwinds.net and 3com make nice TFTP servers you can use for this purpose (I prefer 3com's actually!!)..

Typically tftp would be fine, but in my case there is a bug with files largers then approx 35Mb. The second problem is that there is a [little] known ftp problem with 3Com servers, Cisco, and large files.

I was using the vsftpd daemon on Linux, apparently the router is unable to upload to this server *shrugs*. I switched to the plain ftpd and worked like a breeze.

One thing I noticed was that the transfer was slow, like 600kbps even tho the network is 100Mbps. Anyway, problem solved.
