Linux Lab (Sieg 118)
The EE linux lab systems require an EE account to access. Available linux systems:
- Dell 9020 OptiPlex
- Intel i7 3.4Ghz Processor
- 8 Gigabyte RAM
- 500 Gigabyte SATA hard disks
- AMD Radeon HD 8570
- linux-lab-001 - linux-lab-040 are desktop systems present in room Seig 118. Please do not turn these off, as they may be being used remotely.
- linux12 - linux26 are systems located in a server room, these nodes are useful for remote interactive desktop work, and tend to reboot less often as physical access to these nodes is limited.
- linuxsrv01 - larger system with 64 CPU cores and quite a bit of memory.
- The linux lab systems are licensed and funded only for academic use. Please do not run any research related software on these systems, especially for MATLAB, which is licensed under a substantial academic-only discount.
- Nodes run Red Hat Enterprise Linux Server release 6 (64-bit). For specifics on the CPU, memory, and OS, check /etc/redhat-release, /proc/cpuinfo, and run the free command.
- You may login at the console or remotely via SSH. i.e. ssh linuxNN.ee.washington.edu where NN is the node number, or linuxsrv01.ee.washington.edu for the many-processor system with lots of memory. Unix and Mac OS X systems should have a ssh command available from OpenSSH; Windows systems will need to have a SSH client installed.
- Remote X11 forwarding for graphical programs such as cadence requires a X11 server to be installed on the client system, such as XQuartz on Mac OS X or Xming on Windows. VNC is another option, though requires starting a server on ideally one of the linux lab server room systems.
- Always lock your screen when you are away from the system.
The UNIX Tutorial for Beginners covers how to use UNIX / Linux systems.
- Your Linux lab home directory will be the same on all the linux lab systems. This means if firefox crashes or otherwise leaves a stale lock behind, firefox will not start on any of the linux lab systems until that lock is removed.
ls -al ~/.mozilla/firefox/*.default/ | grep lock
Another problem may be from libreoffice lock files:
find ~/.config/libreoffice/ | grep lock
Which should be a text file containing the hostname libreoffice was run on. If that instance is no longer running, it should be safe to rm that lock file.
Linux Lab Host key fingerprints (RSA 2048)
Note that the linux lab hosts have both IPv4 and IPv6 addresses, so SSH clients may warn about one or the other address if you switch between a network that supports IPv6 and a legacy IPv4-only network.
