  • DNS
    • dc 192.168.2.20
  • gitolite: git@gitsar:repositoryname. Current gitolite admins are Robert and Wolf. In order to use the repositories you have to create a SSH keypair and send the public key to the gitolite admins. You also need the following entries in your .ssh/config:

   Host gitsar
       User git
       IdentityFile ~/.ssh/pubkey
       HostName gitsar.informatik.hu-berlin.de
       ProxyCommand ssh -q gruenau netcat sar 2222

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 192.168.4.88 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
