Currently Teraterm is probably the best free/open source Telnet/SSH client for Windows environment. It supports both Telnet and SSH (limited scp functionality is also supported via File/send file and File/SSH SCP menu items). In addition to standard terminal emulator functionality (also present in Putty) Teraterm has macro language which allows to automate login to most frequently used servers. Unfortunately few people understand this very important and productivity enhancing (especially for sysadmins) feature of Teraterm.
System administrator can greatly benefit from studying Teraterm macro language as well as adopting more advanced methods of work with this program. See Teraterm Tips. For example Teraterm can log the session. logging can be activated iether via menu or by invoking the program with the option /L (you can achieve that by creating a small wrapper script). See Teraterm log and replay function
For system administrators it make sense to create a set of small batch files that lauches Terterm with a given init file (which allow to specify you the color of the background) and connect macro.
cd C:\Utils\Teraterm ttermpro.exe /F=LGREEN.INI /M=headnode.ttl
Using different color of the background heps to prevent a typical sysadmin blunder -- executing command(s) on the wrong server. See Sysadmin Horror Stories
Teraterm known by the abbreviation `TT' was created in 1994 in Japan. The original author of the Teraterm was Takashi Teranishi. Teraterm was released as freeware and won "Online software grand prize 97" competition held by Japanese tool portal Madonomori in 1997. Takashi Teranishi stopped developing Teraterm in 1998. The latest official version created by him was version 2.3.
In September 2004 group of Teraterm enthusiasts from Japan was able to contact Takashi Teranishi. They obtained the permissions to develop Teraterm further and to distribute it under BSD license. They launched the project at SourceForge.jp and released series of versions starting from 4.00. Support forum was established in early 2005. It is the place where TeraTerm users can ask their questions, exchange ideas, share their experience working with the application, post new feature suggestions or report the bugs. The current version of Teraterm is 4.83 (as of June 2013).
The only right site to download the latest version of Teraterm is Japanese SourceForge site: Teraterm Open Source Project. You can also use LogmeTT site (logmett.com) but I doubt that installing logmett makes sense. The site might be probably is more convenient for the USA users.
During installation you should generally avoid selecting Connect component (which provides tabs) as it does not work well. LogmeTT itself is also mixed blessing and use a different license. Therefore you might wish to avoid installing it too. See additional information at my page LogMeTT
Many older and obsolete versions are still available on various sites and are displayed prominently by Google. The first site in Google search "teraterm" points to abandonware (3.1.3 called Teraterm Pro Web from Ayera) and should be ignored
The product has non-intuitive configuration, but functionality is very good. It provides history of visited sites out of the box and has ability to change the size of screen on the fly. By loading different configuration files (TERATERM.INI by default) you can easily adapt to non standard colors which new servers often present to sysadmins. It can write history of your actions to the file. And of couse macro language is an important productivity enhancement tool. It can be combined with programmable keyboard to perform various, pretty complex operation of the server with one keystroke.
Among the features we can list the following:
# To disable tunneled clear text passwords, change to no here! PasswordAuthentication yes #PermitEmptyPasswords no
You can change the default method via Setup/SSH authentication menu and then
selection "use challenge/response to log in..." (or change DefaultAuthMethod=3
to DefaultAuthMethod=5 in teraterm.ini file). That makes Teraterm
behavior compatible with Putty where this authentication method is a default.
[Resize Menu] ; 80x37 ResizeMenu1= 80, 37
; 110x37 ResizeMenu2=110, 37 ; 120x52 ResizeMenu3=120, 52 ; ; Width: no-change, Height: 37 ResizeMenu3= 0, 37 ; Width: 110, Height: no-change ResizeMenu4= 110, 0
See Tera Term command line for full list of options. For our purposes only three options are important /F, /M and /R:
TTERMPRO [ <host> /F=<setup file>] [/M=<macro file>] [/P=<TCP port#>] [/R=<replay file>] [/T=<telnet flag>]
Option /F is the most important option and it gives you ability to specify the setup file. By encoding option /F in simple batch file you can invoke Teraterm with different setup file which for example have different userid for connection, different color settings, set of servers to connect to etc. You can create several icons each of which load different ini file. .
|By encoding option /F in simple batch file you can invoke Teraterm with different setup file which for example have different Userid for connection, different color settings, set of servers to connect to etc. You can create several icons each of which load different ini file. .|
cd "C:\Programe files\teraterm" ttermpro.exe /F=root.iniThis script invoke Teraterm with the configuration file root.ini that provides login as root account and, possibly, some other settings like, say, the location of appropriate SSH private key.
There are multiple addtional opns that you can specify along or instead of options /F=<setup file>, /M=<macro file> and /P=<TCP port#>.
TTERMPRO host1.mydomain.com /F=ROOT.INI # Use root user for login TTERMPRO host2.mydomain.com /F=ROOT.INI /L=F:\Teraterm\rootlog.txt # use logging TTERMPRO host5.mydomain.com /R=add_ntp_config.tt ; replay a file TTERMPRO host5.mydomain.com /M=transfere_dot_files ; replay a file TTERMPRO myhost.mydomain:23 TTERMPRO myhost.mydomain 23 TTERMPRO 18.104.22.168 TTERMPRO myhost.mydomain /T=0 /P=7 TTERMPRO /C=1 TTERMPRO /F=TELNET.INI TTERMPRO /C=2 /BAUD=9600 /F=MYSETUP.INI TTERMPRO /K=MYKEY.CNF /W="My host" TTERMPRO myhost /B /X=100 /Y=50
Following default values are stored in the Teraterm setup file:
<TCP port#> /B <baud rate> <serial port#> <file transfer directory> /H <kanji code (receive)> <kanji code (transmit)> <language> <macro file> <telnet flag> <icon name> <window title> <window pos (x)> <window pos (y)>
What's really important is the teraterm has macro capabilities that enable automatic login to any conceivable Unix or linux or Cisco boxes (both SSH and telnet logins). Teraterm macro language is documented at MACRO Help Index
Teraterm also can be used as Cygwin terminal (in addition to the entry in the File menu it has a shortcut Alt-G). It is a much better command window then windows CMD and is highly recommended for all Cygwin users
As with most open source product documentation is outdated. For example full capabilities of macro language can be deciphered only by reading NEWS announcements. Here we collected them for your convenience.

messagebox 'time to get more beer!' 'Tera Term'
messagebox istr 'Tera Term'
messagebox 'take one down pass it around,' 'Tera Term'
messagebox jstr 'Tera Term'
Several sample ttl file are included with Teraterm, but they usually need some minor tweaking before they work with real servers. For example:
; sample macro of Tera Term ; ; File: ssh2login.ttl ; Description: auto login with SSH2 protocol ; Environment: generic ; Update: 2004/12/4 ; Author: Yutaka Hirata username = 'nike' hostname = '192.168.1.3' ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; msg = 'Enter password for user ' strconcat msg username passwordbox msg 'Get password' msg = hostname strconcat msg ':22 /ssh /auth=password /user=' strconcat msg username strconcat msg ' /passwd=' strconcat msg inputstr

Special utility LogMeTT written by Boris Maisuradze permits convenient storage of login macros for various servers greatly simplifying the task of getting to the right server in minimum time and with minimum hassle (if macros contain passwords they probably should be protected via encrypted drive or similar method). It permits grouping server by location, by operating system, etc. It is highly recommended and really worth the effort of learning the interface. Among notable features:
Please note that many users try to reinvent the bicycle in a form of yet another macro language for terminal emulation. Expect is a more universal and often more powerful way of doing the same. It frees you from the dependency of somebody design mistakes and the luck of understanding of compiler/interpreter technology. You should learn to use it on Unix. The efforts instantly pay for itself.
The teraterm.ini file contains all the configuration settings and parameters used by the application. You may modify the file directly in editor. or through the executable (teraterm.exe) by changing settings then saving the configuration via the Setup --> Save Setup... menu.
Multiple setup file are possible, for example one for AIX, one for HP-UX, one for Solaris and one for Linux.
Modern versions of Teraterm keep the list recently visited hosts. That's a very convenient feature.

A certain piece of very misleading advice is often given online to users having problems with the way certain command-line applications are displaying in their terminals. This is to suggest that the user change the value of their
TERMenvironment variable from within the shell, doing something like this:$ TERM=xterm-256color
This misinformation sometimes extends to suggesting that users put the forcedAccounting for differences
TERMchange into their shell startup scripts. The reason this is such a bad idea is that it forces your shell to assume what your terminal is, and thereby disregards the initial terminal identity string sent by the emulator. This leads to a lot of confusion when one day you need to connect with a very different terminal emulator.
All terminal emulators are not created equal. Certainly, not all of them are
xterm(1), although many other terminal emulators do a decent but not comprehensive job of copying it. The value of the
TERMenvironment variable is used by the system running the shell to determine what the terminal connecting to it can and cannot do, what control codes to send to the program to use those features, and how the shell should understand the input of certain key codes, such as the Home and End keys. These things in particular are common causes of frustration for new users who turn out to be using a forced
Instead, focus on these two guidelines for setting
- Avoid setting
TERMfrom within the shell, especially in your startup scripts like
.bash_profile. If that ever seems like the answer, then you are probably asking the wrong question! The terminal identification string should always be sent by the terminal emulator you are using; if you do need to change it, then change it in the settings for the emulator.
- Always use an appropriate
TERMstring that accurately describes what your choice of terminal emulator can and cannot display. Don't make an
rxvt(1)terminal identify itself as
xterm; don't make a
linuxconsole identify itself as
vt100; and don't make an
xterm(1)compiled without 256 color support refer to itself as
In particular, note that sometimes for compatibility reasons, the default terminal identification used by an emulator is given as something generic like
xterm, when in fact a more accurate or comprehensive terminal identity file is more than likely available for your particular choice of terminal emulator with a little searching.
An example that surprises a lot of people is the availability of theConfiguring your emulator's string
puttyterminal identity file, when the application defaults to presenting itself as an imperfect
Before you change your terminal string in its settings, check whether the default it uses is already the correct one, with one of these:$ echo $TERM $ tset -q
Most builds of
rxvt(1), for example, should already use the correct
TERMstring by default, such as
rxvt-unicode-256colorfor builds with 256 colors and Unicode support.
Where to configure which
TERMstring your terminal uses will vary depending on the application. For
.Xresourcesfile should contain a definition like the below:XTerm*termName: xterm-256color
rxvt(1), the syntax is similar:URxvt*termName: rxvt-unicode-256color
Other GTK and Qt emulators sometimes include the setting somewhere in their preferences. Look for mentions of
xterm, a common fallback default.
For Windows PuTTY, it's configurable under the "'Connections > Data"' section:
More detail about configuring PuTTY for connecting to modern systems can be found in my article on configuring PuTTY .Testing your
On GNU/Linux systems, an easy way to test the terminal capabilities (particularly effects like colors and reverse video) is using the
msgcat(1)utility:$ msgcat --color=test
This will output a large number of tests of various features to the terminal, so that you can check their appearance is what you expect.Finding appropriate
On GNU/Linux systems, the capabilities and behavior of various terminal types is described using
terminfo(5)files, usually installed as part of the
ncursespackage. These files are often installed in
/usr/share/terminfo, in subdirectories by first letter.
In order to use a particular
TERMstring, an appropriate file must exist in one of these directories. On Debian-derived systems, a large collection of terminal types can be installed to the system with the
For example, the following variants of the
rxvtterminal emulator are all available:$ cd /usr/share/terminfo/r $ ls rxvt* rxvt-16color rxvt-256color rxvt-88color rxvt-color rxvt-cygwin rxvt-cygwin-native rxvt+pcfkeys rxvt-unicode-256color rxvt-xpmPrivate and custom
If you connect to a system that doesn't have a
terminfo(5)definition to match the
TERMdefinition for your particular terminal, you might get a message similar to this on login:setterm: rxvt-unicode-256color: unknown terminal type tput: unknown terminal "rxvt-unicode-256color" $
If you're not able to install the appropriate terminal definition system-wide, one technique is to use a private
.terminfodirectory in your home directory containing the definitions you need:$ cd ~/.terminfo $ find . ./x ./x/xterm-256color ./x/xterm ./r ./r/rxvt-256color ./r/rxvt-unicode-256color ./r/rxvt ./s ./s/screen ./s/screen-256color ./p ./p/putty-256color ./p/putty
You can copy this to your home directory on the servers you manage with a tool like
scp:$ scp -r .terminfo server:
Terminal multiplexers like
tmux(1)are special cases, and they cause perhaps the most confusion to people when inaccurate
TERMstrings are used. The tmux FAQ even opens by saying that most of the display problems reported by people are due to incorrect
TERMsettings, and a good portion of the codebase in both multiplexers is dedicated to negotiating the differences between terminal capacities.
This is because they are "terminals within terminals", and provide their own functionality only within the bounds of what the outer terminal can do. In addition to this, they have their own type for terminals within them; both of them use
screenand its variants, such as
It's therefore very important to check that both the outer and inner definitions for
TERMare correct. In
.screenrcit usually suffices to use a line like the following:term screen

This is a locale and termcap issue which I do not fully understand.
Fortunately I do know a workaround. :) Use this:
LANG C mc
to start mc.

When you use the Solaris telnet command to log in from one site to another, don't forget that you can enter telnet's command mode at any time during your session, usually by entering the following key sequence:
[CTRL] ] (the control key and right-bracket key at the same time)
When this is successful, you'll see the following prompt:
Then, from the "telnet>" prompt, enter "?" to learn more about the available telnet commands. A few commands that will give you more help at the prompt are shown below:
display displays many current Telnet settings
send ? displays commands you can "send" to the remote site
set ? displays variables that can be set
One of my favorites (mostly when fooling around) is:
which means "send this message: are you there?".

Tera Term is an opensource terminal emulator on MS-Windows commonly used by us developers. Tera Term supports a "rich" macro language that can help in automating user actions. These scripts usually remain personal - rarely shared.
In this page, I intend to share the basic scripts that can be used to automate common tasks in the Linux PSP release. The scripts were created with intentional hierarchy to maximize reuse (via inclusion) and minimize redundancy across scripts. Currently, these scripts apply to OMAP35x Linux PSP. But, can be extended easily to other platforms.
Needless to say, these scripts are open to enhancements.
TeraTerm Pro Web is the next generation tool for connecting with remote Telnet and SSH hosts. It is built based on the extremely popular open-source TeraTerm product put out by T. Teranishi in 1999 (click here for original site). In keeping with the original philosophy and spirit of the author, our modified version is completely free!!
Downloads TeraTerm Pro Web works on Windows 95/98, 2000, XP. Here are the latest TeraTerm Pro Web releases:
- version 3.1.3, October 8, 2002. ttpro313.zip
As big-time fans of the original, we realized that there were a host of missing features that could make it immensely more useful, namely:
- Ability to connect via SSH2
- Allow recurring command to be sent to connected hosts (ie: "keep-alive")
- Enhance the TTMacro Language to allow ODBC connectivity and additional scripting functionality
- Have built in web server to accept HTTP requests that:
- Pass one or more commands to the connected Telnet/SSH Host
- Capture resulting text from host until one or more termination strings (or timeout) is detected, then...
- Pass captured text back to waiting browser or web server that initiated the request
- Provide various layers of authentication and encryption for the built-in web server including:
- Base64, MD5, and In-Request authentication
- Allow or require secure SSL communication
- Easy to maintain username & password files
- Provide HTTP listening on any IP/port combination
- Have template-based response and error files that could be easily modified
- Have comprehensive HTTP request logging
