First basic requirement, what is your Linux IP address, and are you able to ping the switch IP address ?

Hello! my  Linux ip is 127.0.1.1

That is Loopback address (with that you are not  going to achive what you like to do)

First configure your Linux IP address either Manually or DHCP, then ping to 192.168.1.254 - if that success only -  then try GUI.

if I understood you correctly, my Internet is working now through my communicator(cisco sg250-08) to my computer.

ping: http://192.168.1.254: Name or service not known

I sure you getting the IP address from ISP Roputer - 100.125.0.1

The Switch acting as Layer 2 only, you need to configure, you need to in that subnet:

Thanks for the help, but I really don't know what to do. When I bought the communicator, I thought that I would turn it on and would configure it via the web, but no ...

Not sure what the condition of the switch, Looks like you ignore the right document i have provided and also mentioned the section to look.

here is the steps :

1. rather than google, focus on the document provided with the section.

2. remove Internet connection from the switch.

3. configure your Debian Linux same range IP

4. then you can able to access the switch to configure.

5. change the VLAN 1 IP address from 192.168.1.X to 100.125.0.X (x is one of the free IP in the subnet and save config.

6. connect back your Internet connection.

7. debian Linxu make DHCP, and you should be able to ping 100.125.0.X IP before you access GUI of the switch.

Hello! After complex manipulations with the keyboard and after I disconnected the Internet wire from the communicator, I managed to enter the web interface, but again I cannot enter the web interface! Am I doing something wrong? Could you tell us more about step number 3! Thank you!

3. configure your Debian Linux same range IP

this is if the switch is in the default IP address ? have you changed this?  if you have changed to whatever IP you should in the same range of IP to get GUI access, also make sure you set up the default gateway in switch towards ISP router. ( disable any DHCP / other settings which not required in switch)

make sure you save and commit the confg.
