Bug #5748
Updated by roox over 1 year ago
The _line_ name is part of the file name of the recording.
"/" should be properly filtered to not have issues.
This happens when you use 'TE2/0/1' as the line name:

Workaround:
create the recording directory manually before the recording happens ...
mkdir -p /tmp//isdntap-TE2/0/
