Web Servers and File Permissions In order to create webpages using your MCECS account, it is important to know how web servers and file permissions work in a Linux environment. This guide is intended for novice Linux users and gives a brief overview of: How Web Servers Work File Permissions in Linux Changing Permissions [...]
List of Common MCECS Linux Systems The following is a table of commonly used Linux systems that can be remotely accessed by MCECS users. Be aware of the following attributes: Certain systems are restricted by departments. You can tell which department can access a system by the second component of the hostname. linux.cecs.pdx.edu [...]
If you actively make use of IPv6 routing over the MCECS OpenVPN, this may affect you. Otherwise, please ignore. On Thursday, November 12, 2020, our OpenVPN servers will stop setting IPv6 addresses and advertising IPv6 routes. We are making this change due to issues some users have experienced with unusual IPv6 conditions on their home [...]
Greetings from the Computer Action Team! Fall 2020 is going to be a remotely-accessed experience for most MCECS users. Whether you’re a student, faculty, or staff, you can learn more about your MCECS account by following this link: https://cat.pdx.edu/users/getting-help/ We have built a resource that catalogs many of the most commonly asked questions we encountered [...]
Logins to most CAT supported Linux systems are moving to a different underlying authentication system (known as “kerberos”). Here are the potential side effects of that change. 1) Login using password This is the most common method used for logging in. With a few exceptions, users will not notice any change. If you are unable [...]
MySQL and Postgres users, As a security measure, we are putting the externally available web interfaces for our user based MySQL and Postgres database servers on db.cecs.pdx.edu behind MCECS authentication. This means that users who want to get to those interfaces will have to first authenticate with their MCECS credentials (login/password). For MySQL details, see: [...]
File Sharing through RDP from Linux Step 1: Create a connection using the Remmina RDP client. For instructions on how to do this, follow our guide here: https://cat.pdx.edu/platforms/linux/remote-access/using-rdp-to-connect-to-a-windows-computer-from-linux/ Step 2: Check the "Share folder" box, and select the folder you would like to be accessible from the drop-down menu. Step 3: [...]
Using RDP to Connect to a Windows Computer from Linux Due to the unique circumstances at the college due to COVID-19, we have opened up computer labs that are normally available in-person for remote access. The terminal server (ts.cecs.pdx.edu) is not capable of handling the increased remote access demands of this situation, so [...]
Graphical Linux applications are called X applications as they use the X Windows protocol to communicate with the display. Unlike the simple terminal (shell) interface for logging into Linux (using an SSH client), running graphical Linux programs remotely requires some setup and consideration. Running a single X application If all you need to run and [...]
Using SSH for Remote Connections in MCECS What is SSH? For links to pages on specialized uses of SSH at MCECS, such as using RDP through an SSH tunnel, see the bottom of this page SSH stands for Secure Shell. It is a protocol that creates a secure connection between two computers using [...]
