I am able to start an xpra session such as xpra start :100 followed by DISPLAY :100 firefox, but I can't get a desktop session running.



When I try something like DISPLAY :100 startx or DISPLAY :100 startkde I get errors such as couldn't get a file descriptor referring to the console and another such 



startkde: Shutting down... 
kdeinit5_wrapper: Warning: connect(/run/user/1000/kdeinit5__100) failed: : Connection refused
Error: Can not contact kdeinit5! 
startkde: Done. 
 vfclists@pxl6  ~/tmp/xpra  Qt: Session management error: Could not open network socket 
kwin: unable to claim manager selection, another wm running? (try using --replace)


There seems two be a number issues here.



  1. One of them is that startkde tries to use the existing display manager, but I prefer to get directly to the kdesktop itself without having to long to the display manager.


  2. The other is that the session seems to require access to a tty which probably results in the ``couldn't get a file descriptor referring to the console` message.


The main thing is that I am not trying to use the physical devices, but in the manner of x2go or vnc where I use a virtual desktop.



If the failure comes from the desktop session trying to use physical resources how can the session be started to avoid that.

          Postfix configuration issue with fips on centos 7; mailgun relay

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
