Your Linux distribution should have OpenSSH prepackaged and, quite likely,
already installed. This should make
scp availabe on the
command line. You may also want to check rsync, which is a command line utility
to copy or synchronize entire directory trees, while transferring only the difference in file contents.
Filezilla is a GUI program for both SSH File Transfer or SFTP.
Install using your distribution's software manager or download from filezilla-project.org.
Lauch the program, choose File > Site Manager > New Site. Configure SFTP connection to
Servertype: SFTP - SSH File Transfer Protocol
Logontype: Ask for password
User: your username on gauss
Click OK to save configuration or Connect to save and connect at once.
Some file managers in Linux — Dolphin, Konqueror, Nautilus … — can (persistently) mount remote directories using
Search for VPN on IT Services' website.
Math VPN uses OpenVPN technology.
- Install OpenVPN and Network Manager's component for OpenVPN.
(openvpn, network-manager-openvpn packages in Debian/Ubuntu).
- Download DigiCert root certificate.
- Add Math VPN connection in Network Manager:
- VPN Connections → Configure VPN.
- Add → OpenVPN → Create....
- Connection name: Math VPN.
- Gateway: 188.8.131.52.
- Authentication Type: Password.
- User name: your Math username
- Password: choose Always Ask
- CA Certificate: point to downloaded DigiCert certificate
- To connect click on Network Manager's applet, VPN Connections → Math VPN.
- To disconnect use Disconnect VPN in the same applet.
Math Email (and the DND)
If you have Math Dept. user account (also known as “gauss” account), you also have a corresponding email account.
Your Math email arrives at (and can be sent from)
math.dartmouth.edu server. It can be accessed
instantly and globally via Webmail — this does not require any configuration! As for email applications, all of them, including mobile,
can be configured to use your Math account using these generic settings:
- Incoming server: math.dartmouth.edu, type: IMAP, port: 143
- Connection type/encryption: TLS
- Username: your Math username
- Password: for the username above
- Outgoing/SMTP server: math.dartmouth.edu, port: 587, protocol: STARTTLS; authenticate with Math username and password

Autoreply message text for your Math mail is in
.vacation.msg in your home directory
Autoreply is enabled by uncommenting the following two lines in
#:0c #|/usr/bin/vacation usernameTo stop autoreply, comment both lines out again, by inserting
#as the first character on each line.
.procmailrc can be edited with any text editor while on
terminal or with a variety of GUI tools from Linux desktop,
for example, Filezilla, Nautilus, Dolphin etc.
BackupsYour workstation can be backed up to Math Dept. network storage. Contact firstname.lastname@example.org for assistance.
HTCondor is available as standard packages in Debian, Fedora and Ubuntu:
apt-get install htcondoror
yum install condorAdjust local configuration file

Joining HTCondor pool as an “execute” node
Instructions above are for configuring HTCondor as a submit-only node.
With only minor changes in configuration this can be changed into submit and execute node.
Please consider adding your workstation as an execute node, especially if it's a fairly new machine.
In your local configuration file
DAEMON_LIST = MASTER, SCHEDDwith
DAEMON_LIST = MASTER, SCHEDD, STARTD ALLOW_WRITE=*.dartmouth.edu, 127.* ALLOW_READ=*.dartmouth.edu, 127.*Restart HTCondor. After a few moments your workstation should appear in
condor_statuslisting. If you have Mathematica, Maple, Matlab or GP/PARI installed, add the following lines to
HAS_MATH = TRUE HAS_MAPLE = TRUE HAS_MATLAB = TRUE HAS_GP = TRUE STARTD_EXPRS = HAS_MATH HAS_MAPLE HAS_MATLAB HAS_GP
Connecting to eduroam Wireless Network
Use settings below with your username as NetID@dartmouth.edu and password:
- Security: WPA & WPA2 Enterprise
- Authentication: Protected EAP (PEAP)
- Inner auth. (EAP method): MSCHAPv2
- Username: email@example.com
NB: Sometimes wireless connection can't be established without using a CA certificate.
In such case choose the DigiCert Root CA certificate from
/etc/ssl/certs on your computer.
