Re: [hylafax-users] Sending blank pages

I managed to fix it, using two workarounds.

As I mentioned in my original post, faxing PS (postscript) files seemed to work. So I decided to try the tiff2ps program. Unfortunately that didnt work either. I still got blank pages.

I then read a post on another mailinglist, sorry lost the link, of someone suggesting the use of tiff2pdf. I tried it and SUCCESS!!.

With the success of tiff2pdf it suggested that the hylafax patch I found, in the SRC rpm for libtiff v3.6.1, was either not applied or not enough to fix the problem. To confirm, I recompiled the 3.5.7 src rpm from another RHEL v3 box and installed it and SUCCESS!!

We've decided to stick with the older version of the library even though it might break gtk2 components:

# rpm -e -f libtiff
error: Failed dependencies:
        libtiff.so.3 is needed by (installed) imlib-1.9.13-23.i386
        libtiff.so.3 is needed by (installed) gthumb-2.4.2-7.i386

        libtiff.so.3 is needed by (installed) cups-libs-1.1.22-0.rc1.9.11.i386

        libtiff is needed by (installed) imlib-1.9.13-23.i386
        libtiff >= 3.5.5 is needed by (installed) hylafax-4.2.5-1rhel4.i386
        libtiff >= 3.6.1 is needed by (installed) gtk2-2.4.13-22.i386

The tiff2pdf solution would require that the /etc/hylafax/typerules be changed but I didnt test it further.

Subject: [hylafax-users] Sending blank pages

Hello,

We upgraded the OS of our Hylafax server (v4.2.5)  running on RHELv3 to RHELv4. We also installed the latest updates too. Upon initial re-configuration under the new OS everything appeared to work OK, both from Windows XP and the sendmail mailer function. Suddenly, for no reason that we can see, when the Windows XP users are sending faxes, the receiving end is getting blank pages. The number of pages are correct, except they are blank! The sendmail mailer side of things is working just fine, the same modems are involved and the same receiving end too and the pages are coming through OK.

Interestingly, I noticed that the faxes being sent from Windows are stored are tiff files while the ones sent by email are postscript. I run the tiffcheck on the tiff files and none are being rejected. Just resized and reformatted.

[bash]#tiffcheck doc9.tif
TIFFReadDirectory: Warning, doc9.tif: unknown field with tag 292 (0x124) encountered.
REFORMAT+REVRES

Document requires reformatting, not in Group 3 format.

Now I did read in the mailing lists about the libtiff bug in v3.6.1. Fortunately it seems that the Redhat packages are already patched. I downloaded the source RPM and when I looked at the list of patches, I found the hylafax patch among them.

Does anyone know why this might be happening?

Thank you in advance.

Vic.
