ssh then telnet vs telnet then telnet
location: linuxquestions.com - date: December 20, 2011
I have a remote Communications shelf running linux.
When I ssh to the shelf, and then telnet to one of the applications in the shelf through port 30000 (I run a system call in C language <system("telnet 10.3.3.1 30000")>, I am able to reach the stage where I enter the user name that the application requires, but Carriage return (CR, hex 13) is somehow received as line feed (LF, hex 10) by the application.
******ssh then telnet output:
Welcome to application
ECHO option - ok
SUPPRESS_GO_AHEAD option - ok
NAWS option - forced to [Width=80, Height=25]
TERMINAL_TYPE - VT100 is simulated by XTERM!
username[8chars]:admin (I hit carriage return here but dosent proceed, checked debug logs of application and it sees LF or hex 10)
This does not happen when I telnet to the shelf and then telnet to the application,
*****telnet then telnet output:
SSH or Telnet to Cisco

I am trying to write a perl script that will ssh to a switch/router and execute some commands. If the ssh connection is refused, it should execute a small block of code to push the IP to an array. Once all the SSH sessions are complete, it should run a telnet sub and use the array created above as input. All is well with the exception of pushing elements to the array. Here is the code:

I am new to this field, please tell me the difference between telnet and ssh besides that ssh is very much secure in transferring passwords over the network.
Can we remote login from linux to MS windows through ssh?
Can we do the same using telnet?
ssh or telnet x forward problem
location: ubuntuforums.com - date: September 3, 2008
My colleague has been using his Windows desktop to telnet into a linux server, and forward the Display back onto his desktop to use some gui application on the server. He has been having some minor problems, and asked me to help him set up a Linux machine to be a client for this.
I was pretty confident that he was talking about X11 forwarding, and I was also confident that this would be an easy task.
Before purchasing a new machine for this purpose, we decided to try it out using an existing linux machine as a client.
I made sure that the server's sshd_config said "X11Forwarding yes", and client's ssh_config said "ForwardX11 yes". Every time he connects, he issues the command "setenv DISPLAY client'sIP:0.0", which seems correct.
I made him try ssh, ssh -X, ssh -Y, and xhost + and telnet, but all of them allow him to connect to the server, but when he runs an x application, it just spits out display connection error. Even xclo
SSH vs FTP on Wifi Network Speed?
location: ubuntuforums.com - date: November 15, 2009
Hi. I have been setting up a local network. All units use 802.11g for communication: OS X 10.6 (Mac), Ubuntu 9.10 (PC) and an Apple AirPort Router.
Here is the issue. Although I read everywhere that FTP should be faster than SSH, I cannot confirm that in my own tests. So far, it seems like SSH is actually faster than FTP! Why? It should be noted that I have only been transferring files with the Mac as Server and Ubuntu as client, i.e. logging into the mac from Ubuntu and transferring files TO Ubuntu.
Is there something wrong with my setup? It's so easy so I cannot see how. The applications I use are the following,
SSH: OS X - Built in, Ubuntu - Connect To Server (Built in)
FTP: OS X - pureFTPd, Ubuntu - Connect To Server (Built in)
Also, what speeds should I be expecting from my network? So far I have maxed out at 550 KB/s (SSH) and often the speed is half of that. It should be noted that FTP and SSH are close in terms of speed, but the latter seems to have the edge.
unable to ssh & telnet using Belkin 54G router
location: linuxquestions.com - date: January 21, 2006
I am currently using Belkin network router 54G for connecting the DSL. I installed RHEL4 recently and i am bale to ping the servers but not able to do a telnet or ssh. Router is using DHCP. I tried to connect from both Linux system and Windows servers. Both i am getting connection refused. I checked the router for any port blocking but couldn't see any. Also, I don't know how to enable ssh or telnet on the router.
Is there a way to access to the main consoles thru a SSH or Telnet session ?
location: linuxquestions.com - date: November 26, 2003
It might be due to the fact that I am used to the ditto tool of QNX.
I am wondering if there is a tool that would allow me once in a SSH or Telnet session to have access to the TTY1 or TTY2 or TTY3 consoles.
I already found that VNC allows me to remote access to the X terminal but that is not what I am looking for. Since I control foreground programs running on the main TTY and that I do not use the X environment.
It might be very obvious to some of you but I am really a at This.

SSH vs. SFTP and data transfer speed
location: linuxquestions.com - date: December 7, 2010
I finally sprung for a gigabit switch for my home network. My OLD Dell Poweredge server, my new desktop and my netbook all have gigabit cards. So now of course I have to play with my new toys and do some testing. OBTW all of the machines are running Ubuntu 10.04 LTS.
I connected from the desktop to the server using Gnome Commander and ssh. I find that the transfer rate as shown by System Monitor is in the range 22 - 24 MiB/s when transferring large files. The network history trace is reasonably flat with a 2 second update interval.
When I transfer the same files using Nautilus which treats the server as an sftp connection I find that the transfer rate is in the range 17 - 19 MiB/s and in some cases not very consistent (it frequently drops by about half for a couple of seconds and then returns to "normal").
The server is not overtaxed as this is all it is doing - ssh and samba - no other services. CPU and memory utilization are minimal. The drives I am using are a
