+ - Ask Slashdot: Linux Login and Resource Management/Restriction in a Computer Lab

Submitted by rongten
rongten (756490) writes "I am managing a computer lab composed of various kind of Linux workstations, from small desktops to powerful workstations with plenty of ram and cores. The users' $HOME is NFS mounted, and they either access via console (no user switch allowed), ssh or x2go. In the past the powerful workstations were reseved to certain power users, but now even "regular" students may need to have access to high memory machines for some tasks.
I ask slashdort, is there a sort of resource management that would permit: to forbid a same user to log graphically more than once (like UserLock), to limit the amount of ssh sessions (i.e. no user using distcc and spamming the rest of the machines or even worse running in parallel), to give priority to the console user (i.e. automatically renicing remote users jobs and restricting their memory usage), to avoid swapping and waiting (i.e. all the users trying to log into the latest and greatest machine, so have a limited amount of logins proportional to the capacity of the machine).
The system being put in place uses Fedora 20, ldap PAM authentication, it is puppet managed, and NFS based. In the past I tried to achieve similar functionality via cron jobs, login scripts, ssh and nx management, queuing system.
But it is not an elegant solution and it is hacked a lot.
Since I think these requirements should be pretty standard for a computer lab, I am surprised to see that I cannot find something already written for it.
Does any of you know of a similar system, preferably opensource? A commercial solution could be acceptable as well."

At least "Windows: The Official Magazine" is doing fine. I can easily speed up my sluggish OS, and if that's not enough, I can fix any problem, and as the ace in the sleeve I can find out how to reinstall Windows in just 1 hour. Once again we can see, that if I am in the proprietary software domain, information is easily available, and my workflow is never interrupted.

+ - Nokia to Buy Mobile Phone Base Station Business from Panasonic->

jones_supa (887896) writes "Panasonic has apparently reached a basic agreement to sell its cellphone base station business to Nokia. Panasonic will part with the base station operations of subsidiary Panasonic System Networks, which include wireless control systems for communications equipment. The transaction's value is likely to be in the billions of yen. According to MCA, a Tokyo-based mobile industry research company, Japan's base station market was worth about 260 billion yen in fiscal year 2013. Nokia is the market leader with a 26% share. Since 2007, the Finnish company has had a partnership with Panasonic to develop products for NTT Docomo's LTE high-speed telecommunications services. Now Nokia intends to capitalize on Panasonic's ties with NTT Docomo to further expand its market share in Japan."

An anonymous reader writes "The government of Kerala had recently issued a government order to all government departments in Kerala to explore moving to GNU/Linux given the recent end of life announcement for Windows XP. Most of the government offices in the state were using Windows XP and departments have started exploring migration to GNU/Linux. As one of the first major migrations the state legislature has migrated all its IT infrastructure to Ubuntu. The state is expecting a flurry of major migrations to GNU/Linux and possibly Ubuntu over the coming months."

+ - Ars editor learns feds have his old IP addresses, full credit card numbers->

In May 2014, Cyrus Farivar reported on his efforts to learn what the feds know about me whenever I enter and exit the country. In particular, he wanted my Passenger Name Records (PNR), data created by airlines, hotels, and cruise ships whenever travel is booked.

ASK ARS: CAN I SEE WHAT INFORMATION THE FEDS HAVE ON MY TRAVEL?

One Ars editor tries to FOIA travel documents on himself.
But instead of providing what he had requested, the United States Customs and Border Protection (CBP) turned over only basic information about my travel going back to 1994. So he appealed—and without explanation, the government recently turned over the actual PNRs I had requested the first time.
The 76 new pages of data, covering 2005 through 2013, show that CBP retains massive amounts of data on us when we travel internationally. His own PNRs include not just every mailing address, e-mail, and phone number I've ever used; some of them also contain:

The IP address that I used to buy the ticket
His credit card number (in full)
The language he used
Notes on his phone calls to airlines, even for something as minor as a seat change
The breadth of long-term data retention illustrates yet another way that the federal government enforces its post-September 11 "collect it all" mentality."
