problem with scp / ftp

Hi,
i am doing scp / ftp from 1 server to another.

i can do it successfully for small files.

but for large files, The process stops or gives STALLED message after it starts copying.

I am pressing the “ENTER” key at regular intervals in the "putty" console

But still it gives the same problem.

Please suggest

Shalom,

This is almost always due to a name resolution (DNS) or networking problem.

Time to contact the networking folks.

To confirm.

ssh -vvv username@serverhostnaem

Ooops.

scp also has a verbose parameter as I recall.

Demat praveen,

Take a look at your lan cards configuration. Verify that they are in Full Duplex mode or that you don't have a switch problem. I've had aproximatively the same issue and it was a misconfigured lan card,once in 100FD it was good.

Hope this helps

Hi Pet,
how to check this NIC configuration and how to change.

Re: problem with scp / ftp

You'll need to find out which card is being used for your network, so for example if you are using lan1, you can issue a :

lanscan (and look for the third field of the lan1 card which should be the Card In#)

and using that number, issue the command :

lanadmin -x n (where n is equal to the number of the Card In#)

that should return the speed your card is running at
Cooperation is doing with a smile what you have to do anyhow.

Re: problem with scp / ftp

Hi,

With the lanscan command you have all you lancards.

With the lanadmin command.
lanadmin -x to verify
lanadmin -X 100FD to set it.

Be careful if you have a cluster on this server because when you change it, it hang during several seconds.

Hope this helps
