Security Vulnerability Remediation – rlogin

Rlogin starts a terminal session on remote hosts. This appears as a HIGH vulnerability to some security scanners like Nessus. This is a real easy vulnerability to correct. Just comment out login in the /etc/inetd.conf file.

vi  /etc/inetd.conf

Search for the login entry



login  stream  tcp6    nowait  root    /usr/sbin/rlogind       rlogind

Comment it out

#login  stream  tcp6    nowait  root    /usr/sbin/rlogind       rlogind

Save and close

When you run into this problem, you can delete or move the mysql.sock file.

In this instance, we just removed the file:

 rm -rf /var/lib/mysql/mysql.sock

In this instance, we just moved it to a .bak file.

mv var/lib/mysql/mysql.sock /var/lib/mysql/mysql.bak
service mysqld restart

Restarting the service creates a new entry called mqsql.sock
