How do I send a file through 2 hops?

In order to scp from an outside machine to an inside machine, our gateway machines vorlon or shadow must be used.  To get to the end machine, 2 hops are required.  This command utilizes scp's built in funcitons to allow a single command for putting a file from machine a -> gateway -> machine b securely: 

From Machine A:

scp -Cp -o "ProxyCommand ssh username@vorlon.eas.gatech.edu nc machineb.xxxx.gatech.edu 22" c.txt username@machineb.xxxxx.gatech.edu:c.txt

Please note that this is all one line, and you should substitute your username in both places, even though they may be the same. c.txt is the example file name. 

How do I undelete a file under Linux / Unix?

Unless there is a backup (done by yourself or ISG) there is no way to recover a file which has been deleted. Unlike Windows, UNIX does not provide a "trash can" to restore deleted files.

How do I connect to Linux / Unix servers?

To login to the Unix and Linux based servers in EAS you should use an SSH client which can be likened to a secure telnet client.

For Windows based machines a software package such as SecureCRT or Putty should be used.

For Macintosh based machines, Fugu is your software.

For Unix and Linux machines, type "ssh [username]@[server name]" a connection will be established.

How do I change my password on the EAS servers?

If you log into vorlon.eas.gatech.edu, using SecureCRT, you can change your password.

To change your password on a UNIX or Linux machine, open a secure shell session to the server you wish to make the modification to. At the UNIX prompt type "passwd" and press enter. The system will ask you for your current password, then for your new password twice. (Your typing will not show up on the screen).

Passwords must be between 7 and 23 characters, not related to a dictionary word, and contain at least one non-alphabetical character (i.e. a number or special character).

When you have successfully changed your password, the system will tell you that "authentication tokens updated successfully". You can then logout of the server by typing "logout" and pressing enter.

How do I use a sftp client on a Linux/ Unix machine?

By typing: "sftp [username]@[server name]" a connection will be established.

How can I copy files to or from a Linux/ Unix server?

To access files from the Unix and Linux based servers in the EAS you should use a secure ftp client, WinSCP client (Windows systems), or Fugu client (Mac systems).

Where can I find other software not available on campus?

You may visit the MSD (Managed Software Distribution) site to check a variety of software. MSD is a service provided to the University System of Georgia with the goal of providing quality software in a cost effective manner for GT owned equipment.

Also, visit E-Academy Software site to obtain Autodesk and Microsoft Software at educational prices. Software is available for personal use.

In addition, the Georgia Tech bookstore offers a variety of software at educational prices available to the public. Click here to visit the site.

What are the available site license software packages on campus?

Follow the listed links to see the OIT's list of available site license software for GT owned machines.

What are Secure SFTP (FTP), Secure Shell (SSH), and Secure Socket Layer(SSL)?

SFTP (Secure File Transfer Protocol) allows users to connect securely to EAS servers to transfer files - it works similarly to regular FTP.

SSH (Secure Shell) allows users to connect securely to EAS servers with an interactive shell interface - it works similarly to telnet.

SSL (Secure Sockets Layer) is used on all secure web interactions with EAS servers - it works transparently to the user.

ISG only allows secure connections to EAS servers to help prevent attacks and malicious use.

Printing related questions

Printing is available for Faculty, Staff, and Students. Each semester every user is assigned the following printing quota:

  • Faculty/Staff: unlimited/no restrictions
  • PosDocs: $32.00 (400 pages single print or 200 pages double sided print)
  • Grad Students: $16.00 (200 pages single print or 100 pages double sided print)
  • Students: $16.00 (200 pages single print or 100 pages double sided print)

Once your quota has been reached, it is over. You will have to wait until the next semester for a new quota assignment.

If you need to printer larger amounts, we suggest the use of the printers in the library. Please read all about it at the following link http://www.library.gatech.edu/services/printing.php

Where can I find more information about creating posters for presentation?

Click here to follow Dr. Dana Hartley’s advice, or visit the poster advice page from Swarthmore College for tips, tricks, and detailed explanation for poster creation and presentation.

What can be printed?

Posters that are for Georgia Tech academic purposes only.

What format can be submitted for printing purposes?

The EASISG staff can open Microsoft Power Point, Word, Publisher, Excel as well as PDF (created real size with one dimension set to 36 inches), and Adobe Photoshop files.

What size can be printed?

EAS only provides 36-inch wide paper. Always set one dimension (width/length) to 36 inches. Also be sure to set margins of at least 1/2 inch in all sides of your document. The machine is not capable of doing borderless printing. Without margins some information on your document will get cut on the edges.

What rules should posters follow in order to be processed for print?

  • Submit your job for printing at least 48 hours (two business days) in advance. The support staff cannot be held responsible to get a poster finished for a deadline if 48 hours is not given for processing. Please allow a longer period of time for special events like the Graduate Symposium, the AGU conference, or other conferences in which EAS members/groups will participate. The more participants attending will increase the number of processing jobs for the same time frame and the 48 hour-rule has to be strictly enforced.
  • Click here for a detailed schedule
  • Do not use color backgrounds (light or dark) on the whole poster, titles or other places where they are not needed. The EASISG staff reserves the right to refuse printing any poster with unnecessary colored backgrounds because they diminish the quality of the job and are a waste of ink. Click here to see examples.
  • Pre-set the page sizes to 36 inches by “x” inches (“x” max is generally 48 inches).
  • Make sure to proofread and review your job before submission. You may not print more than two copies of a single poster for a single event. Please notice that reprints are also subject to the 48-hour rule. Also notice that the EASISG staff will not make any corrections to your submission.
