[sane-devel] Canon Pixma MP970 scanner: Connection refused]

[Louis Lagendijk]

hello Brian,
could you please do the following:
set SANE_DEBUG_PIXMA to 13
in bash that is 
export SANE_DEBUG_PIXMA=13 
or in tcsh 
setenv SANE_DEBUG_PIXMA=13
and then a scanimage and mail me the logfile? I want to have a look at
the logfileas as this really looks funny.
It would be good if you could also mail me a tcp packet dump (wireshark,
set 
port 8612 
as option when you start logging). It surprises me that the correct
address is detected:
[pixma] Found scanner at ip address: 192.168.1.252 
but then we start sending to 127.0.0.1. This suggest an error in the
reverse mapping of the scanners address.
What does nslookup 192.168.1.252 return? Does that return localhost?
Does /etc/hosts have the scanners address as localhost?

best regards, Louis
