Tutoring Lab Open!! Jan 29th, 2013 Neal McClain The Computer Science Department is offering a tutoring lab in KOM 361-C for 1170, 2170, and 3110 students. Hours open are: Monday: 8am - 11:30pm ; 1pm - 5:30pm Tuesday: 8am - 2pm Wednesday: 8am - 11:30pm ; 1pm - 5:30pm Thursday: 8am - 2pm Friday: 8am - 11:30pm Welcome to Spring 2013 January 10th, 2013 Neal McClain Greetings! Keep an eye on this page for systems status, helpful hints, and so forth. Please read the other postings for information on various things. I’d like to first point out that if you can’t log in to your ranger/linux or shemp accounts then you likely need to renew your CS account. (They expire every semester) – You can renew them with just 2 clicks by visiting the Account Management Utility site. If you need to change your password you may also use the above link. –Neal How to reset your account password October 10th, 2011 Neal McClain To reset your password go to www.cs.mtsu.edu On the right side click the CS Account Management link Enter your Pipeline ID and password You’ll see a box with your account information in it. On the left you’ll see [Change Account Password] Click that and you’ll be prompted for a new password. There’s more information about accounts in an earlier post below. NX and Lion (it’s a Bear) September 15th, 2011 Mac McCarthy For you folks wanting to run NX on your Apple: The short: NX and Lion do not agree. Skip the long if you are not interested. The fix is located below. The Long: Should you care? First read here. Next know that although the NX v4 Beta Client apparently fixed things and the Java applet on the CS Community Site were working harmoniously – NOW… they are not. Apparently in some minor changes to the NX framework, the libraries that we now use are not compatible. For a plethora of reasons – we are not currently able to change our current libraries. The short of the long – it’s broken. The Current Best Practice Fix: Use x11 forwarding over ssh. “ssh -X username@server.whatever” will get you what you need. In Lion this is accomplished by opening a terminal window and entering the above command. An example would be “ssh -X user@ranger1.cs.mtsu.edu”. A few things to pay attention to. The X is capitalized and it matters. You do not need to include the quotes(“). ALWAYS pick either ranger1.cs.mtsu.edu or ranger2.cs.mtsu.edu – otherwise you risk crossing RSA keys at which time you are going to need to learn how to clear your known hosts file here . Wait! Don’t stop reading yet. You still have to be able to open things. Yes, you are going to have to use to command prompt to do this. For scite, you simply enter “scite&” (without quotes). For NetBeans you enter “NetBeans&” (again, without the quotes). Note: ending the command with the ampersand puts the program you just started into the ‘background’, which really just means that it lets your terminal window come back to a shell prompt. If you need another terminal window open try “xterm&”. If you need to open something else, ask your professor, CS help desk, a Lab Assistant, or a SysAdmin. Final Solution: If all else fails, there are two other options. One, use a Windows PC to do your class work. Should you not own one, check the lab hours above; we have plenty available for use. The Business / Aerospace lab on campus is always open. In there you can launch NX from our web page and it should work fine. Two, if you are not a NetBeans user you can learn to use the ‘vi’ (or ‘vim’) editor instead of scite and then you won’t need to have a GUI running to do your work. If you are using the NetBeans IDE that’s not an option, however. Happy Mac’ing. -Mac, one of your friendly SysAdmins. NX Client broken in OS X Lion (10.7) update July 28th, 2011 Neal McClain Well… All of the Mac users are going to have to beware that the NX client will not work as of OS X 10.7 and later until No Machine releases an updated version. As of 10.7 Apple no longer releases “Rosetta” as a component of the operating system. As a result any program that is written and compiled for PowerPC that has been adapted to work for an Intel based set-up will no longer work. Most programs have been making a steady transition away from the PowerPC architecture but many still remain and the NX client is one of them. Until there is an update all Mac users accessing ranger through the client will either have to use X-forwarding or SSH if they wish to upgrade past Snow Leopard. (25 JUL 2011) Update: Read here for No Machines press release and an interim solution. (28 JUL 2011) Update: You can download the Beta NXClient here. Trouble with MSDNAA account? June 26th, 2011 Neal McClain Note: I’m not sure that the information on password still applies. Will update when I know more. –neal Your MSDNAA login is the same as your email account’s fully qualified name. Example: abc4d@mtmail.mtsu.edu Your class has been registered in the system and Microsoft should have sent you an email with password information. Sometimes, however, this either is not sent or it gets SPAM filtered. So, to find your password, go to the MSDNAA site: https://e5.onthehub.com/WebStore/Security/Signin.aspx?ws=464fbc0b-cc9b-e011-969d-0030487d8897&vsro=8 and click the box on the right captioned “Login Help”. The system will email you a new password. Please log out of NX linux...
