connection problems

[Angela Brune <angela.brune1@gmail.com>]

Hi,
I installed Debian 6 on my machine. Everything was going fine, but at
some point, after installing Gaussian 09 and writing in the .bashrc
file the lines I'm reporting below, the connection starting
oscillating.
 Sometimes it goes for 2 or 3 minutes, then it comes back and so on.
Even after deleting those lines the problem persists. I also tried
restarting the network but it won't help.
 I'm pretty sure the problem comes from these lines, because the same
thing happened with two other operative systems and I don't think it
can be a pure coincidence.
 Can anybody help me? Thanks in advance.
The lines I wrote in the .bashrc file are the following:
g09root="dir"
GAUSS_SCRDIR="sdir"
export g09root GAUSS_SCRDIR
. $g09root/g09/bsd/g09.profile


the file g09.profile contains the following lines:
#
# These commands set up for use of Gaussian 09.  They should be source'd
# into each Gaussian 09 user's .login file, after setting the following
# environment variable:
#
# g09root -- Directory which contains the g09 main directory.  Defaults
#            to users's home directory if not defined before entry.
#
# Top directories for the program:
#
gr=$HOME
if [ "$g09root" ]
  then gr=$g09root
