Takeaway: Jack Wallen lists what he considers to be five of the best SSH-ready clients for
Windows and UNIX.
Every IT admin I know depends upon a secure shell at some point. It’s the single best way to
remotely administer a Linux or UNIX-based server. Secure shell allows you shell access to your
servers, without the concern for transmitting plain-text passwords. Of course, shell access isn’t
limited to UNIX-like servers. Even Windows machines can run a secure shell server.
But what about gaining access to those secure shell-enabled servers? What is the best method?
Well, that all depends - do you like the command line, or do you like a nice GUI tool? The good
news, you can have them both. In fact, I have found five of the best SSH-ready clients. All of
these clients are free and very easy to use. You’ll find clients for both Windows and Linux.

Five Apps
1. PuTTY
PuTTY is probably the single most popular secure shell client for the Windows platform. It’s
incredibly easy to use, allows for the saving of profiles, and can be used as a portable tool.
PuTTY is not only free, but open source. PuTTY can also do telnet, rlogin, and raw TCP. PuTTY
has built in support for the secure copy (scp) program.
2. SecPanel
SecPanel is a solid GUI secure shell tool for UNIX. SecPanel supports ssh, scp, and X Windows
tunnelling. This ssh tool also has a built-in key generator and retains a history of your
connections and key operations. Although the GUI does feel a bit outdated (depending upon the
distribution you are using), it is a solid client for connecting to servers.
3. Private Shell
Private Shell is the only client on the list with a price tag. At $49.95 for a commercial license
($29.95 for a non-commercial license), it might seem a bit steep. But when you look at the
features (terminal connection, file transfer connection, database connection (MySQL, Oracle,
Postgres, DB2), CVS/SVN repository access, SOCKS5 proxy, e-mail server connection, VNC
server connection, X11 tunneling, and more), you quickly understand why it has the associated
price. To get those features on any other client, you’d wind up having to bundle other apps
together. Private Shell also has an outstanding, user-friendly GUI. Private Shell is available only
for Windows.
4. Terra Term
Terra Term has been around for quite some time. However, the current version is recognized by
the project’s original creator. Terra Term offers features such as: Serial port connections, TCP/IP
(telnet, SSH-1/2) connections, IPv6 communication, VT100 emulation and selected VT200/300
emulation, TEK4010 emulation, file transfer protocols, its own scripting language, Japanese,
English, Russian and Korean character sets, and UTF-8 character encoding. This is another
Windows-only client.
5. Linux terminal
Linux terminal. That’s right; I cannot create a list of secure shell clients without including the
Linux command line equivalent. By default, nearly every Linux distribution has a secure shell
client (ssh is the command). To connect to a server, you would typically open up a terminal
window and issue a command similar to ssh -v -l jlwallen 192.168.1.1. Of course you will also
have the scp (secure copy) command available, which makes the remote copying of files much
more secure than standard ftp. Of course, this client is only available on Linux and UNIX-based
platforms (Mac included).
Bottom line
Secure shell is a must have/know for many administrators and having a solid client for this task
can make the job far easier. Check out one of these clients and see if you don’t find the perfect fit
for your needs. No matter if you are on Linux, UNIX, Mac, or Windows there is an easy to use
secure shell client to handle this task.
