`Dear all,<br>
Since I upgraded to OpenSSH I have the following problem with DNS:<br>
reverse mapping checking getaddrinfo for <a href="http://hostxxx.retail.telecomitalia.it">hostxxx.retail.telecomitalia.it</a> [_ip_] failed - POSSIBLE BREAK-IN ATTEMPT!<br>
The remote SSH server has always been OenSSH, the issue appeared when the client (OmniOS) got updated.<br>
I have no access to the DNS records. I already have a dynamic DNS configured, but the reverse one is out of my reach.<br>
<br>
I found online possible solutions and I described the issue also here without success: <a href="http://superuser.com/questions/1149850/how-to-disable-the-message-reverse-mapping-checking-getaddrinfo-for-xxx-failed">http://superuser.com/questions/1149850/how-to-disable-the-message-reverse-mapping-checking-getaddrinfo-for-xxx-failed</a><br>
<br>
"UseDNS no" helped me to be able at least to connect, but still I cannot disable the warning. Since I launch daily rsync backups via cron, I get emails every morning without any real security issue (in my case).<br>
Before I pipe the output of rsync through grep to brutally delete that specific warning, is there a better solution I could test?<br>
<br>
Thanks<br>
Olaf<br>
