sshd/mysql errors.

[Marwan Sultan]

hello,

  and how to get an ip of unkown hostname, as you knowm i should add an IP 
addresses to the firewall not hostnames,

# nslookup host73.maxim.net
***  can't find host73.hostname_net: Non-existent host/domain

I found hundreds of this line to in my logs

mysqld[28598]: warning: /etc/hosts.allow, line 25: can't verify hostname: 
getaddrinfo(IP-216-185-173-58.mtntel.net, AF_INET) failed

Any advise? please.
