Hello When sshd has received the username of a linux user from a SSH client, it look likes it send a PTR request on the client's IP.
for example, if 192.168.56.106 start a connection on a sshd server running on 192.168.56.1, this machine will send a PTR request on 105.56.168.192.in-addr.arpa just after the user name has been received. My question is simple: what is the point of doing this request ? I understand that sshd is trying to know if the client has a domain name, but why ? thank you -- View this message in context: http://old.nabble.com/Why-sshd-makes-a-PTR-dns-request-after-receiving-user%27s-name---tp28391111p28391111.html Sent from the OpenSSL - User mailing list archive at Nabble.com. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
