[cups] Getting remote/client username and remote hostname

[Christoph Litauer]

Dear cups users,

perhaps you can help me with a little problem I am not able to find a solution for.

My cups server runs cups 1.5.4 (printhost). I have several kiosk stations running a local cupsd (1.5.2). All kiosks have a ipp-printer configured pointing to the cups server: 

bib01:~# lpstat -v
device for bib-kopierer: ipp://printhost/printers/test

The printer test on the cups server uses the attached ppd-file. As you can see there is a feature "JobType" using this definition:

*JobType HoldPrint/Hold Print: "%% FoomaticRIPOptionSetting: JobType=HoldPrint"
*FoomaticRIPOptionSetting JobType=HoldPrint: "mark\n&&
/usrcode where{pop}{/usrcode()def}ifelse\n&&
(&user;) usrcode (20`date +%y%m%d%R | sed 's/://'`) {setuserinfo} stopped\n&&
cleartomark\n&&
mark {\n&&
        << /JobType 3\n&&
        /JobInfo\n&&
        <<\n&&
                /UserID (&user;)\n&&
                /Time(20`date +%y%m%d%R | sed 's/://'`)\n&&
                /JobID ()\n&&
                isGenuine not isEnhancedFeatures or {\n&&
                /HostLoginName (&user;)\n&&
                /HostName (&host;)\n&&
                }if\n&&
        >>\n&&
        /JobAttr << /Save 0 >>\n&&
        >> /RDeviceProcSet /ProcSet findresource /SetJobType get exec\n&&
}stopped cleartomark\n"
*End


When the client prints to bib-kopierer, the following code is generated:
mark
/usrcode where{pop}{/usrcode()def}ifelse
(remroot) usrcode (201605171114) {setuserinfo} stopped
cleartomark
mark {
        << /JobType 3
        /JobInfo
        <<
                /UserID (remroot)
                /Time(201605171114)
                /JobID ()
                isGenuine not isEnhancedFeatures or {
                /HostLoginName (remroot)
                /HostName (printhost)
                }if
        >>
        /JobAttr << /Save 0 >>
        >> /RDeviceProcSet /ProcSet findresource /SetJobType get exec
}stopped cleartomark


As you can see "&user;" has been substituted by remroot (which is correct) and "&host;" has been substituted by "printhost" (which is wrong).
I think "&host;" should be substituted by the client name originating the printjob.

Is it possible to achieve that? Are there any other variables usable in foomatic printers ppd configs?

Kind regards
