hi and thx for the responses.
yes, it's a wired network. and i really don't have a clue what else i could write except the above mentioned

is there any way then maybe to use network manager in pclos?
i know how to set up the network, but i have a problem here because i don't know how to find the right settings. maybe this would work (originally for opensuse):
You have to configure "wpa_supplicant". From our servers download digital certificate and save it somewhere on your computer. You can do this by copying and running following four lines in the terminal window.
su
wget
http://navodila.sd-lj.si/sites/default/programs/stud-dom.pem cp stud-dom.pem /etc/ssl/
rm stud-dom.pem
Open file "/etc/wpa_supplicant.conf" with text editor:
nano /etc/wpa_supplicant.conf
Delete all other content from the file and copy the following lines. Do not forget to replace identety and password field with your username and password. Save and close the file.
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=0
fast_reauth=1
network={
key_mgmt=IEEE8021X
eapol_flags=0
eap=TTLS
anonymous_identity="
anonymous@sd.uni-lj.si"
ca_cert="/etc/ssl/stud-dom.pem"
phase2="auth=PAP"
identity="
jankok@sd.uni-lj.si"
password="geslo"
}
Because this file contains your password you have to change the file permissions to:
sudo chown root /etc/wpa_supplicant.conf
sudo chmod 600 /etc/wpa_supplicant.conf
Run the following lines of code in your terminal window. This will enable to autorun wpa_supplicant each time you start your computer.
cd /etc/sysconfig/network/scripts
wget /sites/default/files/programs/ifup-wpa_supplicant.
chmod +x ifup-wpa_supplicant
ln -s ifup-wpa_supplicant ifstatus-wpa_supplicant
ln -s ifup-wpa_supplicant ifdown-wpa_supplicant
cd /etc/sysconfig/network/if-up.d
ln -s ../scripts/ifup-wpa_supplicant
cd /etc/sysconfig/network/if-down.d
ln -s ../scripts/ifdown-wpa_supplicant
The system is now configured. If one hour has already passed from the time you entered MAC address in the web application you should have a working internet connection. But before you can start using it you have to run two more commands:
ifdown eth0
ifup eth0
To check if everything is ok run "ifconfig eth0" command; output will be similar to the one bellow (in the second line after the "inet addr:" IP addres should be different form 10.X.a.b):
eth0 Link encap:Ethernet HWaddr 00:11:22:33:44:55
inet addr:13.2.15.190 Bcast:13.2.15.191 Mask:255.255.255.192

Thank you again.
