Wireless network

The wireless network that we advise to use, is eduroam. Authentication is done in one the following way:

Firstname.Lastname@ru.nl and RU password

Employees of Science-departments can request Eduroam Visitor Access accounts, that give visitors access to a separate part of the wireless network. through C&CZ-Operations, tel. 20000. Every employee of Radboud University can provide a guest with access for the rest of the day, by providing the guest a day code (keyword). That code can be found on the the RU portal. For more information, see the ILS website. Guests can also get access through the Library of Science.

Network time (ntp)

Bram Daams — Mon, 19 Sep 2022 16:26:21 +0000

The system clocks on C&CZ managed Linux machines are being kept up to date by using the Network Time Protocol (ntp). Each machine checks at regular intervals its system clock with several designated machines on the network and adjusts their system clock when needed. Whenever the difference between the local system clock compared to the system clock of other servers gets bigger than half a second the clock will be adjusted. If the difference is smaller, the system clock will be adjusted in small steps by slowing down or accelerating a little, to avoid multiple large time adjustments. Because all systems adjust their system clock to the same ntp servers, all system clocks will eventually become synchronized. The local servers are ntp1.science.ru.nl and ntp2.science.ru.nl.
