I have tunneled mixed linux and windows clients to a 'within-firewall client' (that could access the share's host) before, so I know that that, at least, is possible.

But what about tunneling directly from the client to the host of the network share?

Can I have samba listen on port, say, 5559 (just an example), and only accept connections from localhost, and tunnel a client's 5559 to that host - so that the client appears to be connecting from host's localhost? I can't figure out how to set it up. So far, I have samba configured:

hosts allow = 127.0.0.1 ::1 lo
interfaces = lo 127.0.0.1
bind interfaces only = yes
And I'm tunneling from the host:

ssh -R 5559:localhost:5559 shrusr@shrhost -Nf
However, if samba is already running, than TCP forwarding fails. If the tunnel is already running, than samba cannot start. Is what I'm trying to accomplish possible? Is there some other way to do it?

It seems like it should work - I can even netcat myself files across that ssh tunnel. So, netcat has no problem listening to the same port as ssh. Only smbd refuses, and also blocks ssh from that port if started first.

Any advice would be appreciated.

Hi,

  I am having a problem with an SSH connection.    I have a user program connecting to a device like below

    USRPRGM  SSHMODULE  ------->   SSHD    SERVER     TELNET  ----->    DEVICE
              Windows 7 PC                                SOLARIS Unix server                   Proprietary Device


      So the user program opens an SSH Shell using an SSH Module to the solaris sshd server and logs in.
      At the shell prompt the user program issues a TELNET command to make a connection to the DEVICE.
     This ends up as a tunnel between USRPRGM and DEVICE.

     "SO why not use SSH Tunneling to create the tunnel?   My customer who owns the Solaris Server will
not allow TCP Port forwarding with SSH."

      As part of the protocol, the user program sends  $  ACK $ to the device.
A log of the user program shows that the user program received back   $ ^ F $.  (THE ACK CHARACTER IN HAT NOTATION)
I was also able to work with the customer and perform a SNOOP on the telnet side.
Surprisingly, the $ ACK $ was never sent out the telnet port to the device!!!!!!!

   Ok so after doing some reading, I see that a unix style SHELL does/can interpret
many characters as meta-characters.   For example * [ ] ^ and of course $ to name a few.
So I tried issuing the command stty raw,    then wait for the prompt,   then issue the telnet
command.    This test failed, the telnet application on the server never started.    My
user program log shows,  the telnet …

Hi all,

I have installed Tectia client on two client machines installed with Windows 2008 R2. Tectia client comes with an executable scpg3.exe to copy file to a remote host securely.

I am using the public key method for authentication. I notice that on machine A the file copy to a remote host server with SFTP server installed takes around 3 seconds to complete

ON another machine B, I have tried that the file copy to the same remote host server (using the same file) takes a much longer time to complete (~10 seconds). It seems that the authentication takes around ~8 seconds from machine B.

Please advise the possible causes. Thanks.

What AWS values do I need in order to use SSH on an AWS Beanstalk EC2 instance?

And how are these values used in an SFTP/SSH client on Windows 7?

I am trying to run a mulesoft application that ftps a file to a host using jsch. We have an identity file in the windows server where I am running the application.
 
                        JSch jsch = new JSch()
                  jsch.addIdentity(identityFile)
                  jsch.setKnownHosts(knownHostsFile)
                  session = jsch.getSession(user, host ,port)
                  Properties config = new Properties()
                  config.put(STRICT_HOSTKEY_CHECKIN_KEY, STRICT_HOSTKEY_CHECKIN_VALUE)
                  session.setConfig(config)
                  session.connect()

However, when the code hits session.connect(), I am prompted for Kerberos username [xxxxx]: in the anypoint studio console. And the username xxxxx prompted is the username used to login to the windows server that wuns the application. The user in  jsch.getSession(user, host ,port) is a windows service name and is different from the xxxxx.

This code works fine in the mulesoft server where it is deployed. We are trying to get a development environment ready.

We have an FTP server but are now being asked for a SFTP setup.  We've locked down our FTP server so the vendor or whoever needs to access it can only access that server and nothing else on our network but I'm assuming that when data is transferred, it transfers in plain text.
This may be a stupid part to this question == if someone is transferring data using something like FileZilla and the FTP server isn't a SFTP server, can they still choose to use port 22 (the SSH port?
If not, can someone point me to some documentation on how to set up SFTP on our FTP server?

Greeting Experts,

This question is a bit open ended, but what do you all think of TeamVeiwer usage and security concerns?  Also, if you feel it is an unsecure solution, what do you feel is the best secure alternative?  Cost is not a factor.

Hi,

I have a Cisco 1921 Router that I'm trying to shutdown SSH On the WAN Interface on.  I still want to get to the LAN side interface with SSH.  I've created an ACL for it, but not sure if it's correct, and would appreciate some help on whether I've configured the ACL correctly, and a correction if I have it wrong

Thanks in Advance on this.  Here's what I have:

ip access-list extended BLOCK_SSH

Hello!

We have several Sonicwall firewalls installed at various client sites. We are moving from one smarthost provider to another, and we would like to continue to limit inbound email traffic to specific IP addresses, subnets, etc. with the new provider. Since there are numerous entries we need to make on each Sonicwall, is it possible to create a script to push them to an individual firewall all at once? We usually use the GUI, and just recently realized the CLI is available via SSH. Based on a lack of SSH CLI scripting experience, much like the GUI, we can apply settings individually, which doesn't save any time and actually takes us longer than doing it via the GUI. We would appreciate some feedback on if it is possible to script these settings, or if we just need to apply the settings one by one on each Sonicwall. And if it's possible, we're going to need some step-by-step guidance on scripting via SSH.

Thanks!

I tried to copy a folder from one instance to another instance on AWS, but got the following prompt.


root@monitor:/data/lib$ scp -r jenkins root@10.104.0.185:/data/lib
The authenticity of host '10.104.0.185 (10.104.0.185)' can't be established.

Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '10.104.0.185' (ECDSA) to the list of known hosts.

lost connection

I think it's because of public key. The destination server is a brand new server without running ssh-keygen command. What shoud I do to make the scp happen?

thanks.
