One of my customer is using CentOS 5.9 as a webserver. I am getting problem to ssh login often. I am unable to find the reason to solve. I have checked the logs also. Please help me out of this
There are "two many authentication failures for root" messages in /var/log/secure. This is happened with some other IPs, not with my ip. But still ssh is giving problem to me. After few min i can able to login.
#cat ~/.ssh/config
Host domain2.com
StrictHostKeyChecking no
User backmaster
IdentityFile /home/backmaster/.ssh/id_rsa
Please please help me to clear this. Thank you in advance. If required I can provide more information.#cat /etc/ssh/sshd_config | grep -v '#'
