I have a group of machines that are only accessible by users from certain ISPs. One of those ISPs, we'll call abc.net. The example IP address I will use is 1.1.1.1 In my /etc/hosts.allow, I have: sshd: LOCAL, .abc.net This was working for some time, but somewhere along the last few weeks or months stopped working, and I don't know why. /var/log/secure reports the following: sshd[7693]: warning: /etc/hosts.allow, line 10: can't verify hostname: getaddrinfo(host-1-1-1-1.abc.net, AF_INET) failed sshd[7693]: refused connect from 1.1.1.1 (1.1.1.1) The users are real and were able to get access to these machines. I've verified that I can get access to the machines from a different ISP, in fact, most of the users can. It just seems to be this 1 provider that these 2 users have. Any ideas where I can start looking to find the cause of this problem?
