Re: no x windows



yes, thanks. that did the trick nicely.

i did an:
apt-cache show openssh-server | grep Depends | sed -e 's/,/\n'
which of course didn't show the 'Recommends' so i totally missed looking for that.

though, i don't think i'll forget this one again any time soon :)

You certainly don't need X to have a ssh server. I only looked at it
it briefly, but I'm guessing it tried to install the package "xauth",
which is a "recommends" of openssh-server.

The new default for aptitude is to say "yes" to recommends. There is a
way to configure your machine so that it says "no" by default to
recommends. That has been discussed recently on this list.

I can see that you would have trouble find that information in a web
search.  I think that getting a system with X should be as simple as
not allowing it to be installed. I think the problem you are running
into is that the package system is pulling in recommends
automatically.

You can ignore a recommends at the time of installing by doing:

   aptitude install openssh-server -R

I don't use apt-get, but when I search inside the man page...

   man apt-get

...I see the option "--no-install-recommends". So that would translate
into:

   apt-get install openssh-server --no-install-recommends

If you want to set an option so that aptitude says "no" by default
to recommends, you can try this tutorial:

Yes, many computers do not use X, especially server computers.

I think one reason it is not documented is because many people setting
up CLI-only computers, or server computers, are already experienced
with wrangling their package management software.

Hope this helps,

Phil
