[anne aublanc]

Hi,

faxq-helper: can't chdir to /var/spool/fax/outgoing: Permission denied
can't create new job directory, give up

I don't understand...
I had created a fax without problem a few minutes before with the same user.

thank you for your help

I had created a fax without problem a few minutes before with the same user.

This looks like the permissions of "faxq-helper" or the permissions of
the "/outgoin/" directory have been changed.

They should look like this:

-rws--x--x 1 fax fax 70377 Apr 10 2005 /usr/local/lib/mgetty+sendfax/faxq-helper
drwxr-xr-x 13 fax root 672 May 29 08:58 /var/spool/fax/outgoing

the outgoing directory *can* have more restrictive permissions, but the
most important point is that it needs to be owned by the "fax" user, and
faxq-helper needs to be set-uid to that same (!) user.

I need the permissions of the "outgoing" directory, not of the
subdirectories *inside*.

Please do:

ls -lLd /var/spool/fax/outgoing

(the "d" is important)

OK - these permissions are fine. But it could be a directory further up.

Could you please run:

ls -lLd / /var /var/spool /var/spool/fax /var/spool/fax/outgoing

- each of these directories needs to have "x" permissions for the
faxmget user (quite likely: "for every user on the systems"), because
otherwise "chdir" is not possible.

I found!
drw-r--r-- 5 root root 4096 aoû 31 2005 fax
drwxr-xr-x 4 root root 4096 aoû 10 2005 voice

=> chmod a+x /var/spool/fax

drwxr-xr-x 5 root root 4096 aoû 31 2005 fax

it's good now.......!

I don't know what arrived!

thank you
anne.

drw-r--r-- 5 root root 4096 aoû 31 2005 fax

Yes - this would prevent any chdir (except for root) to
"/var/spool/fax/" and any directories beyond.

Hi,

I don't know ;o)
I still have a little problem...
-rw-r--r-- 1 faxmget www 9508 mai 31 00:48 f1.g3
-rw-r--r-- 1 faxmget root 11025 mai 31 00:41 f1.g3
-rw------- 1 faxmget zoro 11818 mai 31 00:28 f1.g3
With user zoro, I can't read f1.f3 and I can't create pdf...
How to make so that zoro can read f1.g3?

Set "umask 022" before running faxspool - if you have umask 077, the
fax will not be group- or world-readable, which can be desired for
privacy reasons.

umask 0022;

thank you!
It's good

I have a test server.
My user zoro receive a mail...
in qmail :
#./Maildir/
|/home/e-smith/files/users/zoro/home/bin/mailman.pl

in mailman.pl :
I use Email::MIME and Email::MIME::Attachment::Stripper to analyze the parts of incoming mail.
I include mail2fax (fronted mgetty) in mailman.pl to analyse the mails body.
I call faxspool if this is ok
I use Net::SMTP and Net::SMTP::Multipart to return a mail with the fax transformed into pdf or the errors if faxspool is not ok.

Now, it is necessary that I finish!

thank you
anne

I still have a little problem...

With user root or www :
-rw-r--r-- 1 faxmget www 9508 mai 31 00:48 f1.g3
-rw-r--r-- 1 faxmget root 11025 mai 31 00:41 f1.g3

But with user zoro :
-rw------- 1 faxmget zoro 11818 mai 31 00:28 f1.g3

With user zoro, I can't read f1.f3 and I can't create pdf...
How to make so that zoro can read f1.g3?
