Read from remote host 192.168.19.210: Connection reset by peer
It's a test server and almost everybody know the root password. Today I changed the root password so I can fix the problem.
I have already stop the firewall and set SElinux to permissive. There is no iptables entries. but the server still act the same as before.
Is there any suggestion to fix the problem?
Thank

1. Reduce the number of people with root password to minimum - max 2-3 persons. if it possible to 1 person.
2. run command "setup" in Firewall configuration setup:
Security Level (Disabled)
SELinux (Disabled)
3. create script with IPtables rules
I had the same problem with CentOS and also with Red Hat.
In my opinion the best option is /etc/init.d/firewall script with Your settings. Run realy stable.
