Reverse DNS
Hello,
My RH 5.2 seems to make reverse DNS, event if I try to communicate with a server in the same network.
I make :
telnet 10.16.1.25 22 Trying 10.16.1.25...
Connected to 10.16.1.25 (10.16.1.25).
Escape character is '^]'.
SSH-2.0-OpenSSH_4.3
And with tcpdump command I can see :
11:08:10.919454 IP 10.16.65.24.37222 > DNSSERVER: 1983+ PTR? 25.1.16.10.in-addr.arpa. (41)
11:08:10.933593 IP DNSSERVER > 10.16.65.24.37222: 1983 NXDomain 0/0/0 (41)
My IP is 10.16.1.24.
Does anybody had already see that ?
Is it possible to disable this reverse DNS ?
Thx by advance for your reply.

Never understood why people worry about the little sh*t.
This is not hurting you in anyway so why worry about it.
To answer your question, this is being done by the program. If you want to stop it then edit the source code and remove this function.

You are accessing an SSH server...Google is your friend.
Google: ssh disable dns lookup
* But I agree - unless this is causing some problem, why worry about it?
