Hello Expert,
I have been attempting to use Hydra-THC for the past few days to scan for Exposed Microsoft SQL databases on our network.  I am using 3 different .txt files (username, passwords, and iplist files) in the following syntax agreement “  >hydra –L  usernames.txt  -P  passwords.txt  -M  iplist.txt  -e ns  -v  mssql ”.  to scan for databases. Instead of getting brute Force attempts I get error messages. Does anybody have idea what I may be doing wrong….. I running Hydra on WinXP SP3 machine w/all the latest updates
Error Message
C:\Documents and Settings\User\Desktop\hydra-7.3-windows\hydra-7.3>hydra -L
usernames.txt -P dic.txt -t 1 -e ns -M iplist.txt mssql

it looks like part of the error msg as depicted in hydra codes in mssql func.
https://github.com/ggd543/hydra/blob/master/hydra-5.9-src/hydra-mssql.c

E.g. hydra_report(stderr, "Error: Child with pid %d terminating, can not connect\n", (int) getpid());

The PID is referring to the socket threads it spawn off to get connection open to mssql ports. The threads on attempts to perform these commands failed and leading to the a./m msg

sock = hydra_connect_tcp(ip, myport);
OR
sock = hydra_connect_ssl(ip, mysslport);

I was suspecting that if we just use single IP address on that same MSSQL server DB instance, it is failing as well. If so, then MS SQL may be having some authentication configured into it such as Windows Auth (kerberos) which is default or simple DB cred login which is supposed to be what Hydra is testing against...
