SSH / Telnet Software

Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. SSH was designed as a replacement for Telnet and for unsecured remote shell protocols. The term telnet is also used to refer to the software that implements the client part of the protocol. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server.

Learn SQL Server Core 2016

This course will introduce you to SQL Server Core 2016, as well as teach you about SSMS, data tools, installation, server configuration, using Management Studio, and writing and executing queries.

Dear Experts,

I am thinking to use SSIS to do the following procedure.

(1) copy many files to Linux machines. then
(2) execute a Linux program (command) to analysis those files. The program will output the result to the local Linux drive
(3) when (2) is done, then pull the result back to Windows machine

For (1) I am thinking of FTP task (by FTP or SFTP)

how about the task of (2) and (3) ?  Could you please help ... Thanks

This is using IBM storwiz v3700 storage. The SSH service is available and we can connect with this SSH by using the assigned user account with correct password. BTW, how to change so as instead of using password, create the key-pair for the dedicated user account?

Thanks in advance.

I need to provide a SFTP service to let my data providers upload files securely.

Do you know a good and affordable hoster?

I don't feel comfortable opening my servers to the web!

Previously when we transferred a 20GB gz  Solaris file down to PC's
local HDD & then from the local PC HDD, transfer to a USB HDD, our
DLP corrupted the gz file when it's transferred from local HDD to USB

We have since resolve that but to prevent untoward corruption in
future for copying of critical files to USB HDD,

Q1:
Does Winscp has checksum feature that checks at Unix end & at
PC end?

Q2:
If so I would rather use Winscp to transfer directly to USB HDD.

BitVise SSH Client
I am new to sFTP.  I installed BitVise SSH Client successfully.  I can connect SSH Server via GUI and download files ok.  But I want to automate and download files without going through GUI.  Any suggestions for command-line script for file download?  I think sftpc is the one to use.  But I don't know to use it.  My setting is Initial method: publickey. Client key: Profile 1.  

sftpc 'SSH Server Name' - I could connect to the remote SSH Server. Then, it prompts for Password.  But there is no password.

Thank you very much in advance.

I have several linux systems. Normally I login on them with my account, and after I login i execute sudo -s, so I can get admin privileges.
Sometimes I need to edit some files or copy some files out of the linux systems and in the past I ofter used the winscp program.
Unfortunately when I login with winscp with my account I don't have admin privileges, and thus I am not able to open and edit needed files, I am not able to copy files out of the system. Can you tell me how to login with winscp with admin privileges

My company has setup an Ubuntu 18.04 server, to exchange files with a client, via SFTP.  We need a high level of security.  We're trying to require authentication with SSH key pairs, AND the Linux OS username and password (not the SSH passphrase). We've got the key pairs working, but it doesn't ask for the password. I'm assuming we're just missing something in the sshd_config file. Hopefully we're not trying to do something that's not possible. Any assistance would be much appreciated.

Thanks!

Hi, when I finished installing OpenSSH, I got the following warning:

Permissions 0640 for '/etc/ssh/ssh_host_ecdsa_key' are too open.

Could you please give me the command line to safely change and set the proper permissions for this folder and its files?

Server: Red Hat Enterprise Linux Server 7.5

Thanks

Become a Microsoft Certified Solutions Expert

This course teaches how to install and configure Windows Server 2012 R2.  It is the first step on your path to becoming a Microsoft Certified Solutions Expert (MCSE).

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

I removed the public SSH key from a server I was managing. THen I generated a new key and overwrote the old one on my laptop. THen I added the key to the server. it added two keys.

I thought it would be best practice to remove the old key and put the new one in. It seems like my old key is still being added to the server. Am I overthinking this?

Does it really not matter and should you not bother with changing SSH keys? I was going to change them by the business quarter.

Hi guys

I'm trying to set up an SFTP server for our company to use. I have a Windows 2012 server and have started to go down the open ssh route etc.

Do you guys have any guides one could follow or recommendations you would make?

If people think Linux would be a better route, then I can go down that route too. I need something that will be stable and not lose/drop connectivity because of some sort of service that needs restarting all of the time etc.

And I have to do this within the next 3hrs:).


Thanks for helping

Would someone have an explanation for this?

Both times I have run this script.

vmkfstools -i "/vmfs/volumes/Date-2016/00 - DNS Server/00 - DNS Server.vmdk" -d thin "/vmfs/volumes/DES Lessons/00-DNS-Serve
r/00 - DNS Server.vmdk"

Open in new window


It gets to around 45%, and then jumps to 100%


Destination disk format: VMFS thin-provisioned
Cloning disk '/vmfs/volumes/Date-2016/00 - DNS Server/00 - DNS Server.vmdk'...
Clone: 100% done.

However, the actual size is 50GB
But the file transferred is only 16GB


00 - DNS Server.vmdk
16.53 GB
Sunday, May 20, 2018, 12:48:59 -0400

This is the actual size


00 - DNS Server.vmdk
50 GB
Saturday, April 28, 2018, 08:23:53 -0400

I have 7 VMs that need to be moved to a new drive, and this is causing some major slowing down issues.
Any ideas?

Also, if using the vmkfstools GUI is a better route to go, that would complete this without this issue.
Then please, tell me how to use the GUI, as I cannot find any information on using it.

Hello All;

I have a 1TB drive of which has 11 VMs on it.
Taking up about 95% of the space.
I purchased some 500GB driver, I am in the process of moving the VMs over.

What I have done.
#1:
Using the datastore, I chose the VMs and I "Moved" them.
It is going to take a few days to move the ones I selected over, about 426GB.

#2: I tried the OpenSSH
Just to move one of the VMs over that is 60GB, will take over 24-hours.

Code for the SSH

[root@localhost:/vmfs/volumes/5b005dd5-2ce20e85-e704-001517fcd2e8] scp -r "00 - DNS Server" root@192.168.2.101:/vmfs/volumes/Date-2016/"00\\-\\DNS\\Server"

Open in new window


How can I make this go faster?
It is only going from one drive to another drive, on the same server.

Thanks

I have a Dell laptop (running Windows 10) where I'm hosting OpenSuSE Linux (Leap 42.3) in a virtual machine. Although I can ping the virtual machine, I haven't been able to connect to it using the SSH protocol. As far as I can tell, the secure shell demon is running on the Linux system. I've tried a couple of SSH Windows clients – specifically, SecureCRT and SecureFX. Additionally, I've tried running the SSH client from the Windows command prompt. I haven't seen any error messages. Instead, the connection simply times out.

Networking is not my forte, but I'm familiar with SSH. I've configured it on UNIX systems many times, but that was years ago. These days I'm doing so only on rare occasions. Consequently, there's usually some small detail that I overlook. Any assistance would be greatly appreciated!

Unable to access FTP server using local account created.  Ftp server is 2003 and not using IIS, but OpenSSH.
User seems to have all the permissions needed to access through WinSCP, but I keep getting the access denied message when attempting to connect.
I'm not sure whether or not I did not add this user somewhere with permissions, whereas I am not an avid FTP server administrator.
Any help would be appreciated.

We have a partner that has a MySQL / Maria DB Master server.  We have a slave and want to replicate against their master.  Some want to use the builtin SSL replication and others want to tunnel via SSH.  Can anyone provide some recommendations or pros and cons of each.  Any security, maintenance issues to consider?  Also, I assume that since we would be replicating against their master, they would have to run with the ssh port listening, not our slave?  Thanks

Have a new 3650 configured from scratch, I'm trying to get ssh/radius authentication setup.  I went through a guide to setup on switch, I have several others that are working so i know the server is setup correctly, but when i try to use it on the switch, SSh works, and i can log in with local creds, but AD creds don't work. Thinking I'm missing something.  was hoping someone could take a look over my config and see if anything stands out.. Thanks
