UBUnix is an operating system using RedHat Enterprise Server
Linux with academic software installed that you can connect to from
a personal computing device.
UBUnix is a legacy Linux based time-sharing environment similar
to computing services offered before the popularity of personal
computers and graphic user interfaces.
UBUnix must be accessed through the Internet using terminal
emulation programs such as PuTTY, ssh and sshfs; File Transfer
Protocol programs such as SFTP, Fetch and FileZilla; and remote
windowing software such as X-Win32 and X11.
UBUnix does not have a Graphic User Interface and requires
familiarity with Linux commands through a command-line interface.
Unless you have a specific and compelling reason to use UBUnix, we
strongly suggest using popular personal computing alternatives with
Information about UBUnix is primarily for people who are already
knowledgeable with Linux and UNIX based time-sharing environments
to document locally developed and configured UBUnix solutions and
UBUnix only accepts connections from non-UB (remote) locations
by affiliated UB faculty, staff and students that are made using
If you do not have a secure connection to UB as described above,
use a Web browser to visit remote.buffalo.edu and
complete an IP address registration using your UBITName and the IP
address of your remote computer.
Many ISPs give a new IP address each time you connect. This
would require you to visit remote.buffalo.edu every time you
connect to the internet and wish to access UBUnix. However, very
often the IP addresses you are given from your ISP will have the
same first two "octets". For example:
- First Time: 192.168.14.88
- Second Time: 192.168.56.23
- Third Time: 192.168.56.71
Notice that each time the IP address started with
To access UBUnix from any IP address that starts with "192.168."
(or whatever the first two octets of your IP address are), leave
the first two parts of your IP address on remote.buffalo.edu as
they are and make the last two parts of your IP address blank.
All files in UBFS can be accessed from UBunix:
- cd /ubfs to reach the top of the UBFS directory
- cd /ubfs/Myfiles/
1st_UBIT_LETTER and 2nd_UBIT_LETTER are the first and
second letters of your UBITName) to reach your Myfiles space.
- cd /ubfs/collab to reach the top of the Collaboration
(shared) directory tree.
