Disclaimer: This is a very large topic, and much too broad to be covered on a single support page. There are many other sites (yes, entire sites) which cover the topic in more detail. We'll link so some of them below. This page is meant to be just the essentials.
Logging in for the first time
To login to Beocat, you first need an "SSH Client". SSH (short for "secure shell") is a protocol that allows secure communication between two computers. We recommend the following.
- PuTTY is by far the most common SSH client, both for Beocat and in the world.
- MobaXterm is a fairly new client with some nice features, such as being able to SCP/SFTP (see below), and running X (which isn't terribly useful on Beocat, but might be if you connect to other Linux hosts).
- Cygwin is for those that would rather be running Linux but are stuck on Windows. It's purely a text interface.
- OS-X has SSH a built-in application called "Terminal". It's not great, but it will work for most Beocat users.
- iTerm2 is the terminal application we prefer.
- Linux has SSH built-in as the command ssh. It can be used from any Terminal emulator.
- There are many SSH clients for many different platforms available. While we don't have experience with many of these, any should be sufficient for access to Beocat.
There are many ways to transfer files into and out of Beocat. We generally suggest a SCP program, of which there are many.
- There are others for many different platforms. Above are some of the ones that we have experience with.
How to get help
There are many sources of help for most Linux systems.
Unix man pages
Linux provides man pages (short for manual pages). These are simple enough to call, for example: if you need information on submitting jobs to Beocat, you can man qsub. This will bring up the manual for qsub.
GNU info system
Not all applications have "man pages." Most of the rest have what they call info pages. For example, if you needed information on finding a file you could use info find.
