  • In case of an non-fixed IP-address, the dhcpd-daemon dynamically registers the host-name, as proposed by the dhcp-client, with the DNS for sar.informatik.hu-berlin.de.
  • If no name is proposed the default name for a dynamicly assignd IP address 192.168.X.Y is set to dhcp-X-Y.
  • For WGTs with MAC-addresses 00:0f:b5:X:Y:Z the name wgt-Y-Z will be assinged . (Note: this is only valid if no static IP is assigned and if no conflicting static dns-entry exists; leading 0 in the MAC-addresses are droped. Example: 00:0f:b5:3c:0a:17 -> wgt-a-17)

HWL-Testbed Services

The toolchains for compiling software for the different hardware platforms can be found at 192.168.4.117 in the folder /testbedhome/testbed/software/openwrt. Ask Robert for credentials.

The nodes themselves can be accessed from 192.168.4.117 or 192.168.4.188 via SSH. The nodes can mount a NFS share provided by these computers in order easily exchange data. Use the script /testbedhome/testbed/helper/host/bin/environment.sh to mount the share. Example:

/testbedhome/testbed/helper/host/bin$ NODELIST="wgt74" ./environment.sh mount
