dtlogin's genauth routines were trying to open and read /dev/mem on
linux and (presumably) bsd systems in order to obtain random data used
in creating an auth key.
This is bad for a variety of reasons. Newer linux kernels (at least
on 3.2) issue the following warning to the kernel logs:
"Program dtlogin tried to access /dev/mem between 100000->102000."
Now on linux we will use /dev/urandom, and on CSRG_BASED (bsd) systems
we will use /dev/random to obtain some entropy.
In dtlogin, you can select the language to switch to by selecting it
via Options->Language. Unfortunately this was also including '.' and
'..', since this list is built dynamically by scanning a directory.
Now we screen out '.' and '..'.
What we really need are more fonts installed, like all of the xf 75dpi
and 100dpi fonts. 100dpi looks much better than 75/72 dpi, especially
on any display larger than 1024x768. Of course, in the far future, we
should use the anti-aliased TT fonts everyone else uses these days
anyway.
Added proper SharedDtSvcReqs in lnxLib.tmpl and CplusplusLibC in
linux.cf. This allows the libstdc++ dependancy to be properly
declared for libDtSvc so that it is not neccessary to hardcode 'CCLINK
= g++' in the Imakefiles of programs linking angainst libDtSvc.
