Recently, my desktop hard disk crashed. So I reinstalled Linux and created a new set of private RSA keys for authentication. However, two of my remote UNIX servers still uses old DSA keys. I do not remember root password for those servers. I do have backup of private and public DSA keys and currently stored in /backup/home/user/.ssh/id_dsa and /backup/home/user/.ssh/id_dsa.pub. How do I force my ssh clients to use identity file /backup/home/user/.ssh/id_dsa to get back to my remote UNIX servers?
How do I install my SSH public key ~/.ssh/id_rsa.pub onto a remote Linux / UNIX server automatically from Linux workstation / Apple OS X laptop without using scp and/or copy & paste method?
How do configure to release and obtain VIP (virtual IP) when nginx is dead, down or system is rebooted for the kernel upgrades?
I‘ve compiled and install an application called gpass on CentOS v5.6. But, when I run the application it does not accept any password from $HOME/.gpass and displays the following error on screen:
libglade-WARNING **: could not find signal handler ‘gpass_authentication_on_response’
How do I fix this problem and use the gpass software?
How do I change password under Redhat Enterprise Linux?
How do I read and/or view logs files under OpenSuse / Novell Enterprise Linux?
My Squid proxy server running on port 3128. Since this is frequently scanned by adversaries looking for proxy servers; I’ve changed port to 10000 and restart squid. But my squid is not working on port # 10000 it only works on port # 3128? How do I force Squid to listen on uncommon port under CentOS Linux v5.3?
