None that I know of. I have copied a 25 GB file via scp without any problems. There should be no issues with 50 MB.

Hi :

File size isn't an issue for the transport layer. The destination system might limit the largest file it can store (i.e < 2GB if largefiles isn't set) but this clearly isn't the case here. Your 'ulimit' might also constrain the maximum file size at your destination, but that doesn't seem to be happening here, either.

Google turns up an number of threads to suggest that mixing SSH-1 and SSH-2 protocols may lead to the message you saw.

Hi (again):

Why would you want an old version of Secure Shell?

The HP software depot notes that "...HP provides software technical support for HP-UX Secure Shell for only the latest, currently shipping version and the immediately prior version of the product."

If you can upgrade to the current version (because you are running 11.11, 11.23 or 11.31) then I would consider doing that. However, this may _not_ be the source of your problem, since you said, "i tried with other user and from root with different file, it works".

Hi Admins,

Now i transfered the same file using scp...

I dont understand whats happening..

i suspect some network fluctuations..But n/w guys telling there was no issue with network..

One more doubt..
I was getting below error in syslog while scp issue
< bad="" packet="" length="" 1896786796.="">
I was trying with scp..but it shows sftp in syslog.

This is second time m facing problem with scp.But both the time issue resolved itself..strange..

Hi:

> I was trying with scp..but it shows sftp in syslog.

So what? I suspect that this is intentional to make tracking easier.

A good overview of the differences between 'scp' and 'sftp' is here:
