Event putty SSH client is not working on WS2012...

To make myself clear: I would like to connect to a SSH server from WS2012.

Then you need to contact your network/server administrator.

I am the system administrator and I have access to everything.

For some reason Windows Server (tried also on WS 2008 R2) does not allow connection on port 22/SSH.

I have a background application to download/upload data from FTP (on port 21) and SFTP servers (on port 22) using WinSCP dll. The application runs on a very old Windows XP machine and it has been running for years.
Now I am trying to move the application to a WS2012 R2 server and I noticed connection to SFTP servers times out. So I started to track the issue and finally I decided to use putty SSH (CLIENT) on WS2012 R2 to see if the problem was with WinSCP or not. None of them work, I also tried Bitvise with no luck.

I think there is definitely something on Windows Server blocking port 22 or SSH. I do not need to setup a SSH server, I just need a SSH client able to run on Windows Server 2012 R2.

If anyone had the same issue please reply to this post as I still unable to make SFTP/SSH/port 22 CLIENT works on WS2012R2.

Many Thanks in advance

Wireshark

Connecting from W10:

sourceIP destIP TCP 66 39882 → 22 [SYN] Seq=0 Win=8192 Len=0 MSS=1460 WS=256 SACK_PERM=1
sourceIP destIP TCP 54 39882 → 22 [ACK] Seq=1 Ack=1 Win=65792 Len=0
...
OK


from WS2012R2:

sourceIP destIP TCP 66 40389 → 22 [SYN, ECN, CWR] Seq=0 Win=8192 Len=0 MSS=1460 WS=256 SACK_PERM=1
then nothing hence time out

Both PC and Server share same LAN, same Gateway, same router, Firewall turned off on the server (already tried to add exception IN and OUT for port 22).

any clue?

What error are you getting?
Can you connect with any other SFTP client?

Connection Refused / Connection Timeout

We can connect through a W10 machine but I want have the application running on a server instead.
My W10 pc and WS2012 server are on the same network using the same gateway (hence same firewall rules applied).

I also asked a friend of mine to test on his brand new WS2012 and same problem occurs.

If a try an FTP site I am able to connect from WS2012.

Looks like WS2012 is blocking some SSH/port/service by default?!?!

I will try other client and let you know

I think is definitely an issue in WS2012: I tried SmartFTP, same issue... can connect SFTP from W10 cant connect SFTP from WS2012...
