Package: cupsys Version: 1.1.23-15 I have cupsd.conf configured to use encryption IfRequested.
Adding printer kalle always works just fine without encryption # lpadmin -p Kalle -P ~lpetos/xr_dc440.ppd -v ipp://kalle/ When using encryption it does not work most of the time, repeating command several times may get it to work eventually. # lpadmin -p Kalle -P xr_dc440.ppd -v ipp://kalle/ <Just hangs - no response, several minutes> <CTRL-C> Traces # strace -o lpadmin-E.log lpadmin -E -p Kalle -P xr_dc440.ppd -v ipp://kalle/ <CTRL-C> See attached logfiles. The lpadmin-E-ok.log is from a execution that actually works even with encryption. By filtering one can see intrerresting similarities and that a SIGPIPE is received when it goes bad. # egrep "send|recv|connect|accept|close" lpadmin-E.log | less # egrep "send|recv|connect|accept|close" lpadmin-E-ok.log | less The cups error_log show that something unexpected is received "Bad request line "^W^C^A" from localhost!" Several times, until the last one when it actually succeeds. If the fault is a buffer overrun in the server then I guess it is a security related bug. /Petter
