| ====== SSH secure shell ====== | ====== SSH secure shell software ====== |
| |
| Secure Shell (SSH) is the recommended replacement for telnet for remote access to Unix and VMS systems. Similarly, Secure File Transfer (SFTP) replaces FTP. Ssh can also be used to tunnel less-secure protocols and make them work over restricted [[:computing:network:firewall_and_proxies|firewalls]]. | ===== Windows ===== |
| |
| | One of the best options for SSH on Windows is SecureCRT, from [[http://www.vandyke.com/]]. It is a commercial product but we have a large number of licenses for an old-ish but useful version (5.0.5). You can download the installer from MyPhys, along with the license information. We have some [[secureCRT|basic directions for using SecureCRT]]. |
| |
| | Also available from MyPhys is an even older but still-functional **SSH Secure Shell Client** (from ssh.com). The installation includes a **Secure File Transfer** client which is a very useful replacement for FTP. |
| |
| | You can obtain installers for the above programs from our [[https://www.physics.umn.edu/resources/myphys/software/|MyPhys software download page]]. |
| |
| ===== Windows ===== | There are also a few free clients, such as [[http://www.chiark.greenend.org.uk/~sgtatham/putty/|PuTTY]]. |
| We recommend **SSH Secure Shell Client**. The installation includes a **Secure File Transfer** client which is a very useful replacement for FTP. You can obtain the installer from our [[http://www.physics.umn.edu/resources/computing/download/|software download page]]. | |
| |
| A second option is SecureCRT, from [[http://www.vandyke.com/]]. SecureCRT has slightly better terminal emulation than the ssh.com product. We have a large number of licenses for an older version of this (v3.3). You need to enter this [[http://www.physics.umn.edu/resources/computing/download/sshlicense.html|license information]]. ADCS also offer licenses for the current version of SecureCRT, which is preferable in some ways (for example, it allows multiple sessions in different tabs of the same window). [[secureCRT|Directions for using, here]] | An excellent program available for free evaluation is [[http://mobaxterm.mobatek.net/|MobaXterm]], which includes a tabbed ssh client, secure file transfer, an X11 server, and many other features. Only the "home edition" is free, so please make sure you abide by their license terms. |
| | |
| There are also a few free clients, such as [[http://www.chiark.greenend.org.uk/~sgtatham/putty/|PuTTY]]. | |
| |
| For file transfer (SCP or SFTP), we suggest using **SSH Secure Shell Client** (above), or [[http://winscp.sourceforge.net/|WinSCP]]. | For file transfer (SCP or SFTP), we suggest using **SSH Secure Shell Client** (above), or [[http://winscp.sourceforge.net/|WinSCP]]. |

| | If you want, you may also purchase [[http://www.expandrive.com/windows|Expandrive]], which can map a remote filesystem over ssh as a windows drive. |
| ===== Mac OS X ===== | ===== Mac OS X ===== |
| |
| SSH is provided with Mac OS already. | SSH is provided with Mac OS already, for command line use. |
| |
| For remote file access over SSH, we recommend **Macfusion**, from [[http://www.macfusionapp.org/]]. Note that before installing this program you must have **MacFUSE**, from [[http://code.google.com/p/macfuse/]], installed. | The best option for remote file access over ssh is probably **FileZilla**, from [[https://filezilla-project.org/]]. More information on our [[:computing:software:ssh:filezilla|FileZilla setup page.]] |
| |
| ===== Unix ===== | |
| Most modern Unix systems come with a form of SSH already installed. If not, the standard is OpenSSH from [[http://www.openssh.com/]]. | |

| * **OpenSSH** is available as a part of **cygwin**, at [[http://cygwin.com/]] (free/open-source). Directions for installing it can be found at [[http://tech.erdelynet.com/cygwin-sshd.html]]. There is also an **OpenSSH for Windows** project at [[http://lexa.mckenna.edu/sshwindows/]], which is designed for easy installation. | * **OpenSSH** is available as a part of **cygwin**, at [[http://cygwin.com/]] (free/open-source).
