Ruhollah, I'm not an electronics guy either, but for starters (while you wait for a better answer):
Two situations: 1. The user SSH comes into the Head through a single NIC which does little else. 1.1 First, swap out that NIC. 1.2 Swap which slot the NIC is in 1.3 Swap the cable 1.4 Check the environment for recent changes that might affect temperature or RF interference. 2. Not 1. above. I'd want more information about your layout, but an example would be a recent change at the desktops that you didn't know about (such as installation of a Service Pack); you might check with the desktop admins. Good luck. Peter On 5/29/07, Ruhollah Moussavi Baygi <[EMAIL PROTECTED]> wrote:
-------------------Dear all at Beowulf, As I mentioned in my previous email, I have a problem with ssh connection to our Beowulf cluster. I did put an email in Beowulf mailing list group, but with no answer. It is hard to believe that nobody knows anything about this problem, so, I sent this email for the second time. Following please find the content of my previous email. I WOULD BE GRATEFUL FOR ANY COMING ANSWER! Best, Ruhollah Moussavi Baygi------------------- Hi everybody at Beowulf, I have a serious problem with ssh connection to our cluster. Every hint/help/suggestion, which can help me to solve it, is highly appreciated. Most of the time, when users want to connect and run their programs from their own PCs, the ssh connection failed, especially during transfer files from/to head-node. Our user's PCs are mainly WindowsXP, so they use packages like SSH Secure Shell for connection and file transfer, or Putty for connection and WinSCP for file transfer. The error massage is as follows: ' Disconnecting: Corrupted MAC on input' or ' Disconnecting: bad packet length...', followed by a long integer. This problem has practically made our cluster unusable. So, I would be thankful for any coming advice. -- Best, Ruhollah Moussavi Baygi -- Best, Ruhollah Moussavi Baygi _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
