Re: [hylafax-users] Errors Sending To Some Faxes



That worked nicely. Now here's the followup question: since this is a 56K modem, and since sendfax will use the fastest speed supported by both the sender and receiver, why am I seeing a remote "best rate" of 33600 bits/s and an actual send of 14400 bits/s? My command line is:

sendfax -n -f "alex@xxxxxxxxxxxx" -R -D -G -s letter -d *7014439999999 ~/test.pdf

(sending a test page to a modem I have access to, so I can ensure that things work right)

the log shows:

This is, of course, less of an issue than faxes failing altogether...but it would be nice to be able to get the full speed of my modem.

Alex

Re-running faxaddmodem's the easiest.

::Replying off-list b/c this is probably a dumb question::

...and how exactly can I do that? Do I need to re-run faxaddmodem, or can I just tweak the "ModemType" value in /var/spool/hylafax/etc/config.ttyS0?

BTW, thank you for responding so quickly.

Alex

Alex,

Reconfigure your USR to operate in Class 1 and compare the results - you
should see a significant improvement.

Subject: [hylafax-users] Errors Sending To Some Faxes


Hello All,

I recently set up a version 4.3.0 Hylafax server that acts in conjunction with a web site I run to allow people to fax their Congresspeople directly. I know that Hylafax is set up at least marginally well, since I've used it to send out a large number of press releases recently, and I've had success with some limited testing sending to both the US House and Senate.

However, I'm getting odd errors sending to some of the faxes over on the Senate side. Here's an example session:

This doesn't appear to be a permanent error, as I later sent a fax to this particular machine. However, I've seen this sort of thing happen more than once, and I'm concerned about larger-scale failures if a large number of people start using this service.

Based on the above transcript, does anyone have any idea what's going on? The modem is an external serial USR 56K, and the base system is Ubuntu 6.06. I'd be happy to provide any other details necessary to troubleshoot this issue.
