Dear Centos Users:
I installed Centos 7 on my server a few months ago. While using ssh, there is always a strange message "Write failed: Broken pipe”. It forces quit of SSH. It’s really annoying as it happens very often with irregular time interval - from a couple of minutes to a few hours. I have been working using Linux (Red Hat, Fedora and Centos) over 15 years. This didn’t happen for me even under centos 6.6. I have tried the following approaches, but none of them can help. I wonder if it can be solved by reinstall the system again. But it’s time consuming to reinstall a lot of softwares.
1. Login via Mac, Windows, Linux systems from different computers.
2. Modify sshd_config on the server as suggested by many posts:
TCPKeepAlive yes
ClientAliveInterval 60
3. Modify ~/.ssh/config file on my local computer:
Host *
ServerAliveInterval 60
4. Login ssh using -Y instead of -X.
5. add ‘unset autologout’ in my .cshrc.
6. I checked IP address with the internet administrator, and it works well.
7. add a file named autologout.csh with ‘set autologout=0’.
Do you know a good solution? Thanks!
Cheers,
Hua
