ORBIT-USER: telnet and ssh to nodes

[Ivan Seskar]

Hi Vanessa,

You have to first do:

apt-get update

before issuing "apt-get install ..." (to sync apt with the repository).

Hello,

I'd like to have the nodes in the sandbox to exchange emails.
I'm trying to install the sendmail packet in each of the nodes but i get
not found errors. Is sendmail the best option? also, which would be each
nodes recipient name? (or should i use their ips 10.1.101.17/18?

The output of apt-get is:

node1-1:/etc/apt# apt-get install sendmail Reading package lists... Done
Building dependency tree... Done The following extra packages will be
installed:
  liblockfile1 procmail rmail sendmail-base sendmail-bin sendmail-cf
