Hi,

Find the below error when i tried with sftp.

Please help on this.

Assuming that you're using OpenSSH-based SSH software at the client side, the scp command calls "ssh [user@] scp [options] -t ". The ssh connection effectively forms a special kind of a pipe between the local and remote scp processes.

I guess the first word of the error message is missing its first letter: it should be "Disconnecting: ...".

Your error message is coming from the ssh command, which is receiving from the remote server something it cannot understand.

For further troubleshooting, more information is required:

- Does the error happen in the beginning of the connection, or does the copy proceed for a while before terminating?

- Which versions of SSH are used, both on the client and on the server? (If the version is very old, could you try updating to a newer version, to see if the error goes away?)

- Does the same error appear if you try a regular ssh connection instead of scp?

- Is there some sort of customized access control, e.g. a firewall in the network or a software IPfilter on the remote host?

ssh/scp is not compiled with 64 bit file support, so the maximum size of the file you can copy is about 2.4 G

#ssh -V

this should give you the version of your openSSH and as you know scp is a part of SSH package

About the error, What I do is only speculate as I dont have any concret evidence of why this happens. But I have been through such problems

I was ending up thinking that there might be a time limit or something like that to reset the scp connection.

Hey I dnt ask you about this.

Does the destination filesystem has sufficient space to accomidate the new file when u tried the transfer ??

[himacs]

Yes
