X-Trace

[John F. Morse]

I have a user concerned about privacy, specifically his IP being displayed.

After his request several years ago, I changed the "NNTP-Posting-Host" option 
in /etc/news/inn.conf to:

addnntppostinghost:     false

That took care of one possible concern, but now X-Trace is the issue.

Can the X-Trace header field be silenced in INN 2.5.2? This is a compiled 
version with TLS running on Squeeze.

I realize INN 2.6 will change this with the new Injection fields.

I'm not a Perl programmer. Perhaps commenting out lines 588-589 in 
/etc/news/filter/filter_innd.pl or changing 589 would work?

       8 # $Id: cleanfeed 306 2010-01-04 10:48:45Z cleanfeed $
...
     585     # Try and ascertain the source news service.
     586     if ($hdr{'Injection-Info'} =~ /^\s*($Hostname)[\s;]/) {
     587         $postingservice = "$1"
     588     } elsif ($hdr{'X-Trace'} =~ /^\s*($Hostname)\s/) {
--- 589         $postingservice = "$1"
+++ 589         $postingservice = 0;
     590     } else {
     591         $postingservice = 0;
     592     };

Or something in filter_nnrpd.pl et al?
