[mrtg] cfgmaker error: No response from remote host

[Steve Shipway]

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/172.16.20.1'
 --global 'Options[_]: growright' --output /etc/mrtg/switch.cfg
 --subdirs=HOSTNAME --ifdesc=nr --ifdesc=descr --ifdesc=alias
 --ifref=name 'He\@pr at 172.16.20.1'

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 :)
