IRDIA assigned some fixed IP to be used by the s-bots in the lab. This howto provides all the information required to access the s-bots and to modify the associations IP/s-bot.
IP Address Range & Associated S-bots
Here below, there is the list of IP addresses allocate for the s-bots. The firs column shows the IP address, the second is the name of the stored in the DNS, the third is the actual number of the s-bot binded to the address.
IP | DNS Name | S-bot # |
---|---|---|
164.15.10.150 | sbot1 | 19 |
164.15.10.151 | sbot2 | 15 |
164.15.10.152 | sbot3 | 8 |
164.15.10.153 | sbot4 | 12 |
164.15.10.154 | sbot5 | 21 |
164.15.10.155 | sbot6 | |
164.15.10.156 | sbot7 | |
164.15.10.157 | sbot8 | |
164.15.10.158 | sbot9 | |
164.15.10.159 | sbot10 | |
164.15.10.160 | sbot11 | |
164.15.10.161 | sbot12 | |
164.15.10.162 | sbot13 | |
164.15.10.163 | sbot14 | |
164.15.10.164 | sbot15 |
For instance, if you need to login into s-bot number 15, you can type ssh root@164.15.10.151 or ssh root@sbot2.ulb.ac.be.
What is the Role of the Base-Station
When switched on, the s-bots connect to the wireless LAN. The wireless base-station is nobel.ulb.ac.be and works as a bridge between the wireless and the fixed networks. This means that the base-station receives all the packets for the s-bots from the fixed network and routes them into the wireless one, and the other way round too. No manipulation of the packets occurs.
How are IP Addresses assigned
After the sbots connected to the wireless lan, they broadcast a DHCP request for an IP address. Being this a normal packet, the base-station routes it to the fixed network. The DHCP server on iridia.ulb.ac.be receives the request and answers to it.
