No. I don't have a problem; I think that Peter's original message was to let me have access to the information if I needed it.

I bought it some years ago, at a time when most wireless devices needed to have a few hoops negotiated before they would work (usually by running the Windows Driver in a wrapper). The company that sold it guaranteed that it would work on Linux (I can't quite remember who it was (maybe www.linuxemporium.co.uk)) and they haven't been proved wrong yet. -- Terry Coles -- Next meeting: Bournemouth, Tuesday, 2015-05-05 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR

Re: [Dorset] Remote Desktop to a Raspberry Pi
Hi Terry, I fixed my problem by completely removing xrdp from the Pi (including a purge) and re-installing it. That seems to match http://ubuntuforums.org/showthread.php?t=1314336 and the bugs it links to. Something about whether xrdp pulls in vnc4server, bad, or tightvncserver, good. There should also be /var/log/sesman.* or similar that would hopefully give more details than that dreary `error - problem connecting' in the GUI. WRT xrdp's and sesman's status, if you find a process ID then you can list what IPv4 interfaces and sockets they are listening on, e.g. perhaps it's only loopback. Here's an example with part of Postfix, showing it listening for incoming SMTP connections only on the loopback interface. $ sudo lsof -a -p `pidof master` -i 4 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME master 1304 root 12u IPv4 8665 0t0 TCP localhost.localdomain:smtp (LISTEN) $ Not the problem this time as a re-install wouldn't have helped. The purge removed /etc configuration files; perhaps there was something there amiss. Cheers, Ralph. -- Next meeting: Bournemouth, Tuesday, 2015-05-05 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR

Can I also just say Duh? Can I just say that I now feel properly put in my place. Why didn't you just say RTFM and we can all feel nostalgic for the 1970/80s and the Flame wars on the Newsgroups? You should also write to Linux Format about this; their latest set of articles on the Pi include one on Remote access. They don't mention X either (although they do advocate VNC, which I think is a crock, so maybe they deserve a bit of criticism). What's wrong with using X11 or as often known X-windows. It's a client/ server system designed from day one to allow remote machines to display graphics on another remote server. It's the default on most Unix/Linux boxes, all be it with remote and local systems being the same machine on todays PCs. There's nothing wrong with using X11 except: 1. It never occurred to me. This may be because the last time I used X11 for anything serious it was in conjunction with Cygwin to get access to a SparcStation. I can't say the performance was particularly scintillating, so I might have rejected it anyway in favour of RDP, since, unlike the Sun boxes, modern computers (including the Pi) can run RDP. 2. I need to access the full desktop, not just some graphical utilities. I have read that this can be done over X, but see below. 3. My recollection is that X is a bit of a faf to get working, due to having set the DISPLAY environment etc. I'm sure that once it's working, it's very easy to do, but it was a piece of p**s to get RDP working (until it broke), so I used it. 4. Performance. This may be only a perception, but I see that Tim has expressed the same opinion. When I first learned about X some 20 or so years ago, my understanding was that bandwidth was the main problem, so again I probably wouldn't have tried it, even if I'd thought of it. 5. I have used RDP in a number of scenarios for years, so I know what it can do and felt it to be the right approach. 6. I can also access the Pi from a Windows box, should I wish to. Anyway, rant over. If anyone's interested, I fixed my problem by completely removing xrdp from the Pi (including a purge) and re-installing it. -- Terry Coles -- Next meeting: Bournemouth, Tuesday, 2015-05-05 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
