   Mv> I was not harping on D'Bridge, I was trying to pinpoint the source of the   
   Mv> problem by elimination. The inner workings of D'Bridge have always been   
   Mv> treaetd as if they are state secrets. So I had to work on a minimum of   
   Mv> knowledge.   
       
   That is a slight exageration.   
       
   D'Bridge is exactly as Kees describes. It generates an outbound-queue in a   
   base-36 format. This is how it was made to work "here" and still does ...   
       
   DBUTIL moves everything for a specific client into a dedicated directory,   
   in this case 2:250/1   
       
     c:   
     cd c:\db   
     dbutil move 2:250/1 C:\DB\BINKD\22501   
       
   Deleting a trailing FLO-line   
       
     c:   
     cd c:\db\binkd\22501   
     del ????????.flo   
       
   Check if there is content in that directory   
       
     c:   
     cd c:\db\binkd\22501   
     dir /a-d/b 2>nul >nul   
     if errorlevel 1 goto end   
       
   Unpack possible packed content into pkt-files   
       
     c:   
     cd c:\db\binkd\22501   
     call c:\db\bat\unpack.bat   
       
   Create FLO-file of whatever content is in the dedicated directory and let   
   BINKD do its thing zith it ...   
       
     c:   
     cd c:\db\binkd\22501   
     d:\soupgate\genflow 250 1   
     copy ????????.flo c:\binkd\outbound   
       
     :end   
       
   You know how to read a batch file.   
       
   Mv> The way it looks now, is that the version of binkd that Ward used was the   
   Mv> exception. Despite the fact that it showed the IPv6 compile option was   
   Mv> used, it would not do IPv6. So replacing it was NOT useless in tracing   
   Mv> the problem.   
       
   This is the version I am about to use now ...
