Cable connection
Members of Club Sincoolka with Network membership can use sockets in the wall to connect to the network.
Sinkuleho dormitory: all sockets in your room should work.
Dejvická dormitory: only two sockets are working in each room.
If your device is known, you will be connected to Internet straight away. If not, you should be redirected to our Information System - SINIS.
Also, if you need a cable, come to the LAB during office hours; we have a couple of them to give. ;)
Security
All devices connected with an Ethernet cable get not only an IPv6 address, but a public IPv4 address as well, therefore, it is necessary to have a correctly configured firewall on such devices. Alas, people do not, so, unfortunately, we had to close some ports that people commonly leave open by mistake:
Service | Protocol | Port |
---|---|---|
FTP | TCP,UDP | 20,21 |
Telnet | TCP,UDP | 23 |
SMTP | TCP,UDP | 25 |
DNS | TCP,UDP | 53 |
NetBIOS | TCP,UDP | 137,138,139 |
SMB (Samba) | TCP,UDP | 445 |
RDP (remote desktop) | TCP,UDP | 3389 |
Microsoft SQL | TCP,UDP | 1433,1434 |
OracleDB | TCP,UDP | 1521,1830 |

PostgreSQL | TCP,UDP | 5432,5433 |
Memcached | TCP,UDP | 11211 |
MongoDB | TCP,UDP | 27017,27018,27019,28017 |
Redis | TCP,UDP | 6379 |
DirectJet/AppSocket/Raw/HP print/… | TCP,UDP | 9100 |
LPD/LPR (printing) | TCP,UDP | 515 |

Ostatní | TCP,UDP | 6666 |
If you need to have one of these ports open, please visit us during the office hours or send us an email.
