hello ,

I run a script to see if a line is present in a file and I do this from a bounce machine which is allowed to access all the servers in the park, I have a total of 4300 servers.

When I run my shell script, I get the following two errors

error 1:
Matching host key in /root/.ssh/known_hosts:12042
Are you sure you want to continue connecting (yes / no)? yes
Warning: the ECDSA host key for '[myserverlinux1]: 77' differs from the key for the IP address '[xx, xx, xx, xx]: 77'
Offending key for IP in /root/.ssh/known_hosts:6424
Matching host key in /root/.ssh/known_hosts:12044
Are you sure you want to continue connecting (yes / no)?

error 2
sys @ ld000psp0001's password:

I want to find a solution so that my script ignores these two cases.

thnaks in advance .

From the sparse information you give, I conclude that you should disable host key checking: https://www.shellhacks.com/disable-s...-key-checking/.

Technically that would work, but you might want to check whether you should/are allowed to do that....

Since there are 4000 remote servers, a solution based on SSH certificates might be preferable. A known_hosts file with 4000 entries is monstrous.

Shameless plug (I am sure that there are many other and easier to read tutorials).
