Setting
`env.torconnectmethod 'port'`
leads to the error:
```
munin-run tor_bandwidth
env.torconnectmethod contains an invalid value. Please specify either 'port' or 'socket'.
```
Removing the quotes solves that, because the quotes are part of the variable value.
["There is no need to quote the variable content."](http://guide.munin-monitoring.org/en/stable-2.0/plugin/use.html)
Fixes
```
munin-run tor_bandwidth
File "/etc/munin/plugins/tor_bandwidth", line 450
if router[0] == "r":
^
IndentationError: expected an indented block
```
ans use single quotes constantly also for GeoIP.dat filename
