Network interruptions to student rooms campus Etterbeek fixed

Access to port 111 from outside the university network to be denied
As a security precaution, access from outside the VUB/ULB university network to port 111 - a port mapper - will be denied as of Wednesday, 15 February 2017. If you require access to this port, contact the ICT-Helpdesk. Read more...
Port 111 is a port mapper with similar functions to Microsoft's port 135 or DCOM DCE.
Technical details and issues: http://www.speedguide.net/port.php?port=111
Security Concerns: Provides rpc port map without auth, has no filtering or logging, rpcinfo probes can quickly find Unix hosts.
Other security issues: https://en.wikipedia.org/wiki/Portmap
The port mapper service was discovered to be used in Distributed Denial of Service (DDoS) attacks and Distributed Reflective Denial of Service (DRDoS) attacks in 2015. By using a spoofed port mapper request, an attacker can amplify the effects on a target because a portmap query will return many times more data than in the original request.
As port 111 poses quite a number of security concerns, the network team will proceed in denying access to port 111 from outside the university network as of Wednesday, 15 February 2017.

Telnet from outside the university to be deactivated on Monday 26 September
As of Monday, 26 September 9 AM, users will no longer be able to log in into a server at the university from a remote computer outside the university using the Telnet protocol. If you need to log on onto another computer, use the more secure protocol secure shell (ssh). Read more...
Telnet allows users to log in into a server from another computer.
Because of the numerous intrusion attempts that have been going on lately which on occasion have resulted in connectivity issues to university services (Denial of Service), the telnet protocol will be disabled for computers outside the university.
Therefore, as of Monday, 26 September 9 AM, accessing a server at the university from a computer outside the university using Telnet will no longer be possible.
If you need to log in into another computer, use secure shell (ssh) which is more secure as well (telnet connections are not encrypted and therefore not secure, especially through unsecured wireless networks).
If you have a server that only is accessible with telnet and require it to be accessibly from outside the university, send an email to ICT-Helpdesk requesting an exception. Please also motivate your request and include the name and IP address of the server.
Occasional lockouts to university services from outside the university network
The lockouts to university services from outside the university network should be solved. The network team has implemented a number of changes that should prevent these lockouts from occurring.
