Is it possible to have multiple SFTP connections for the same host,username and port??

I am running a Centos 7 linux server, i am runnin open ssh server, and client. I did a recent test to see if the ssh is working correctly, and what i found out was i could only using my internal IP address to access my server from my workstation. I tried to use the public static ip and i get a timed out error. I checked my ports 21,22,  to make sure they are open through port forwarding through my wireless router. They check out to be open, I am using firewalld as a firewall, and i  did notice that my selinux gave me an message basically asking me do i want the sshd server access to a particular file. I am not sure if selinux is the issue. But i want to find out if it is a permission problem, or  selinux issue. The actual sshd server when checked on staus shows it is running fine. Please help

We have a Linux server and after it was scanned for any security vulnerabilities, we got one about "SSH Weak Algorithms Supported".  I tried to make a change to the ssh_config file under /etc/ssh/ to remove the support for any "arcfour" algorithm, but after another scan, it is still showing that this vulnerability exists.  Can anyone tell me exactly what I need to change?  This is my line in the ssh_config file:

 Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc

Thanks in advance!

There is a security system scanner that needs to access a server to scan.  If it states the below, what would be the command to allow?  I've check sshd_config and thought allowed IPs would be in that config.  But it seems I need a command and the system previous setup owner is gone at my current new job.  

RHEL 7.4 Maipo

If you are running IP filters or IP wrappers you will need to permit the systems to access your system via Secure Shell (SSH) on port 22. The IP addresses for the systems are

1.2.3.4
2.3.4.5
and
2.5.6.7

These are just placeholder IP addresses.  
What would be the command line only to add this?

Hi all,

I've been trying to access our Cisco SG300 via URL and putty and no luck. The switch is fine and running. I've been wanting to go in and bring a port alive.

Earlier, for the first time in weeks the GUI loaded via URL on the browser so I tried to log on and it wasn't doing anything. Also tried HTTPS and nothing (GUI.PNG) also I exit browser and reload it says... Unable to connect, etc on most browsers(cisco_browsers.png)

I also tried console access with PUTTY.
SG300 -> male to male serial cable-> DB9 to USB cable. Device manager shows COM4 so I set that into putty.

Connect to: COM4
Speed: 115200  (have tried 9600)
Data Bits: 8
Stop Bits: 1
Parity: NONE
Flow Control: NONE

SSH and Telnet was also not working.

SSH- file attached (cisco_putty_ssh) ...  "Disconnected: No supported authentication methods available (server sent: public key)

Telnet- file attached (cisco_putty_telnet) ... "Network error: Software caused connection abort"


I've completely rebooted my laptop and the SG300 switch as well.

We use SFTP on our AS400 to Send data to a client on port 10022 (was set up a long time ago), and it works perfectly.  We have a new client who wants us to SFTP using port 22, which is the default port.  When we try to SFTP it tries to use port 10022.  I looked and the SSH config file shows port 22.  Why is SFTP getting port 10022 from, and more importantly how do we change it to use port 22 for this client?

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.

Hi.
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?

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

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.

Hello. I am trying to access Elastic Search Server on AWS.
1. What would the ssh be to access the Elastic Search Server?
2. Once I am able to access it where would I place a python script in order to feed data into the Elasticsearch server?

PS C:\Users\hpBill> ssh root@search-wbcelastic-*******.us-east-1.es.amazonaws.com/
but just get this:
