In both the latest release version & the development (5.21 & 5.30BETA1). When I try to use Ncat with OpenSSH client as ProxyCommand with verbose flags for Ncat it's screw's up the connection, because NSOCK debugs to STDOUT!!! I believe you have a purpose behind this, so at least I wish for a deferent flags for the verbosity of Ncat & Nsock. Keep the good work,
That's a good idea. I've added a note to todo/nmap.txt to allow logging to stderr. In the meantime, I think that Ncat will not print any Nsock messages if you use -vv and not -vvv.
Also in the release version (5.21), I have encountered a problem with the socks4 proxy when Ncat is been used inside OpenSSH client's ProxyCommand, for some reason Ncat will not pass the incoming stream back to the ssh client. I couldn't figure way. Here is a sample output: OpenSSH_5.4p1, OpenSSL 1.0.0a-fips 1 Jun 2010 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Executing proxy command: exec ncat -v --proxy 127.0.0.1:4444--proxy-type socks4 SOMESERVER 22 ..... ..... Ncat: Version 5.21 ( http://nmap.org/ncat ) Ncat: Connected to proxy 127.0.0.1:4444 debug1: ssh_exchange_identification: and here it's just hangs.
Does this happen with the latest version too? Please post the exact commands your are using (you can use SOMESERVER in place of the server name). This includes the ssh command and the command to start the proxy.
