Now that I see the error with a little more of thoroughness, it seems
that when doing a copy/paste in the CLI, the name of the module was
incorrect and for that reason I got that error message :-). Now get a
different error:

alderamin*CLI> module unload chan_dahdi.so
alderamin*CLI> module load chan_dahdi.so
[May 21 06:15:34] WARNING[25314]: chan_dahdi.c:1233 dahdi_open: Unable
to specify channel 2: No such device or address
[May 21 06:15:34] ERROR[25314]: chan_dahdi.c:7662 mkintf: Unable to open
channel 2: No such device or address
here = 0, tmp->channel = 2, channel = 2
[May 21 06:15:34] ERROR[25314]: chan_dahdi.c:11270 build_channels:
Unable to register channel '2'


Can this be due to something incorrect in the configurations that I
mentioned in a previous post? Whatever happens, could that be the cause
by which the command 'dahdi show status' is not found?

Regards,
Daniel
