It was around this time I had a eureka moment, I remember I had buried on my desk some where a thinclient converter USB stick (plug it into an old PC and boot from it and it converts the PC to a thin client), a little investigation showed that there was an iso image on the usb stick which after a bit more investigation allowed me to to see the program that makes up the install. The only program that stood out was *os.rrdp (the format was os.sane, os.scim).

Re: [Dorset] How do I find out the file system type?
I find newer Windows systems will only work with xfreerdp instead of the rdesktop ( http://www.rdesktop.org/ ) program I've always used, unless you specifically modify their security settings.

In case it is relevant, I have been using Remmina for RDP for quite a while now. At some point, something changed and now I find I have to set Security to RDP, rather than Negotiate in order for it to work. -- Andrew. -- Next meeting: Bournemouth, Tuesday, 2015-04-07 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 -- Next meeting: Bournemouth, Tuesday, 2015-04-07 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] How do I find out the file system type?
Hi Tim, After attempting to mount it, have a look at the end of dmesg(1)'s output for any information from the kernel filesystem modules about what they did or didn't like. Strangely my system does not have a dmesg log file, I had a good search (looked in the normal /var/log/ ) but there no log to be found The `(1)' after `dmesg' means its man page is found in section 1 of the manual. It's a command, not a log file, though some distros may choose to copy its output to a log file now and again. Just run `dmesg'. 'sudo file -s /dev/sdd*' works here to tell me that I have an x86 boot sector on /dev/sdd and an ext4 filesystem on /dev/sdd1. Adding '-k' shows more information. ... I moved onto the sudo hexdump, this dumped a load of gibberish where 95% of the readable text in the right hand column was just random, If it really was random then that suggests compression. Did you try the file(1) command Andrew suggested? Do you recognise the boot loader when it's booting? https://en.wikipedia.org/wiki/Master_boot_record#Sector_layout describes how the machine code is located within the first sector of the disk, and probably later stages before the start of that partition. *The reason I am doing this is that these terminal are Linux based and they have a built in RDP client, I am having issue with running RDP on my PC so I was hoping to glean some info from one of these terminals. Seems a long shot. :-) Doesn't mean it's not an interesting way to fill your time though. Perhaps working out what goes wrong in the network protocol, e.g. Wireshark, between your failing Linux RDP client and the server would get closer to a solution; you can look at a thin terminal's traffic to see if you can spot the traffic for a similar activity.
