[mrtg] cfgmaker error: No response from remote host

Sound like cfgmaker is getting confused by the community string and is using the wrong one somehow.

Try experimenting with the number of escape characters for the @ in the community, or use single quotes:

cfgmaker --global 'WorkDir: /srv/www/htdocs/mrtg/'
 --global 'Options[_]: growright' --output /etc/mrtg/switch.cfg
 --subdirs=HOSTNAME --ifdesc=nr --ifdesc=descr --ifdesc=alias
 --ifref=name 'He\@pr at'

if this doesn't work, use 2, 3 or 4 backquotes before the @ instead, I don't know without testing how many times cfgmaker is evaluating it and removing the \ characters.  Really, cfgmaker should have some code to identify problem characters in the community string and escape them automatically...  make the regexp matching 'greedy' so that the last @ is taken as the separator.  But that's someone else's problem :)
