The ssh is work fine, and i an transfer file my laptop and other servers. This file is only 30kb. –  tywtyw2002 Nov 26 '13 at 0:26
    
When you ssh into this server, is it doing any unusual output when you log in compared to your other servers? If the server is outputting something like a message of the day on login, this would confuse scp. –  DerfK Nov 26 '13 at 1:55
