<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am trying to test stunnel to see if it can provide the functionality we need. We are a Windows shop.<o:p></o:p></p>
<p class="MsoNormal">What we need is for multiple client machines (I call these C1, C2, C3) to connect to our server (S).<o:p></o:p></p>
<p class="MsoNormal">Server S will connect to a remote SFTP server (port 22). I call the remote SFTP server “R”.<o:p></o:p></p>
<p class="MsoNormal">C1, C2, C3 and S are all inside our firewall.<o:p></o:p></p>
<p class="MsoNormal">Currently S can connect and send files to R using SFTP (port 22).<o:p></o:p></p>
<p class="MsoNormal">The problem is that R does not accept a range of IP addresses, and has a limit on the number of IP addresses they can accept.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So, what I need is for C1, C2, C3 to be able to connect to server R using S as a jump host.
<o:p></o:p></p>
<p class="MsoNormal">From R’s perspective, it should be like the connection is coming from S.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Question 1: can stunnel be used to accomplish this?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Question 2: I have installed stunnel in a test server (“stunnel –install” actually from the bin folder), and configured the conf like this:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">[sftp]<o:p></o:p></p>
<p class="MsoNormal">accept=127.0.0.1:22<o:p></o:p></p>
<p class="MsoNormal">connect=some.remote.server.com:22<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I tried to use Winscp SFTP client to test a connection, but it times out.
<o:p></o:p></p>
<p class="MsoNormal">I then checked S, and I don’t see anything listening on port 22. I did “netstat –a” and I don’t see anything listening on port 22.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Was something wrong in the “stunnel –install” command? Shouldn’t it be listening on port 22?<o:p></o:p></p>
<p class="MsoNormal">Also, I uncommented the entry for log, but I don’t see any log file in the stunnel folder/subfolders<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">; Debugging stuff (may be useful for troubleshooting)<o:p></o:p></p>
<p class="MsoNormal">debug = info<o:p></o:p></p>
<p class="MsoNormal">output = stunnel.log<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for your help,<o:p></o:p></p>
<p class="MsoNormal">Cecilia<o:p></o:p></p>
