We don't enable root access to the system proper.  But, each
vserver has a 'virtual root' account that allows the installing
of RPMs and other system modifications.  Log into your vserver
with SSH and then 'su' your vserver's virtual root account.

For networking, there are 'safe raw sockets'
(http://www.planet-lab.org/raw_sockets) which make many raw
socket operations available.

As to firewalls, in general, PlanetLab nodes are supposed to=20
be on the open Internet and not have any firewall between them
and the network.  But the realities of site administration and
the wild-west Internet has led to some port blocking on some
of the nodes.  There is not a list of these.

Subject: [Planetlab-users] [Fwd: Two questions]





Hi,
I'm new in  PlanetLab and I would ask two questions about iteration=20
between machines and software installation:


1) To compare the performance of my application, I need to install some=20
software in the nodes. This software needs to be installed as  root. Is=20
it possible install this software as root? Can someone do it for me=20
(i.e., PlanetLab administrators)?

2) my application monitoring different PCs around internet measuring the

bandwidth between any machine in a group. To evaluate this bandwidth I=20
have implemented a Client/Server application. Is there a firewall=20
setting between the nodes in PlanetLab?

Thanks,
   Massimo.
