When it did run, it ran well. Enough for the members of the exam panel to be convinced anyway. It would also run with graphical programs (you probably know that since you mention Octave), provided that they only used OS facilities (i.e. no direct hardware access) and didn't use shared memory. That last is a killer as far as things like Mozilla/Firefox are concerned, I've got a colleague who keeps a lot of browser instances open for extended periods but since each one uses a block of shared memory to coordinate multiple windows it's not possible to spread the load. I've ended up setting him up a big AMD system, and it's interesting comparing its memory management performance with the slightly smaller Sun he was using until recently: different flavours of Linux kernel behave very differently. The sort of thing that interested me was the case where somebody had PDA-type programs running on a portable system ("Minnie") which could offload work to something more capable ("Mike") when its owner got home and docked it (wireless doesn't really work here, since connections have to be broken fairly carefully). However that obviously mandates that all cooperating systems are binary-compatible, unless this sort of thing is reengineered using e.g. Java (I'm sure somebody has by now) and that all required apps are available (more of an issue). I think it does rather more than the virtualised etc. systems which are so popular these days, and is in practice much closer to some of the classic IBM mainframe OSes which could distribute work over sysplexes- which is probably why Moshe Barr is seen in some of the IBM foramina. RIP, there's no equivalent replacement on PCs (which probably suits IBM fine). -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other

[fpc-other] Networking problem from Linux virtual machine hosting Lazarus
I hope this might be acceptable to ask here even if it is FPC and Lazarus off topic I have created a VMWare WS12PRO virtual machine in which I have installed Linux Mint 17.3 MATE to host FreePascal 3.0.0 and Lazarus 1.6. These are now fine and working. As a last item I need to secure connectivity to the company version control system hosted on a Windows server on address 10.0.0.7 This network is on-line on the VMWare host PC (Windows7 X64) via VPN. I have set the virtual machine networking to NAT so it will use the host networking system and it should be able therefore to use the VPN channel to reach the 10.0.0.7 server. This is the addresses of my system: Main PC (VMWare host): IP=192.168.0.137 Mask=255.255.255.0 GW=192.168.0.129 VMWare virtual adapter for vnet8 on main PC: IP=192.168.80.1 Mask=255.255.255.0 Linux Mint virtual machine: IP=192.168.80.130 Mask=255.255.255.0 GW=192.168.80.2 Server on VPN network: IP=10.0.0.7 Mask=255.255.255.0 I know that this should work but I feel that there is something missing on the Linux side to make it actually start working... On previous Linux virtual machines (VMWare Workstation 7 level) I did not have to do anything else than connect VPN on my host PC to make that network also available on the virtual computer. Does not work now... I have tried adding route 10.0.0.0 on the linux side as follows: bosse@mint17mate ~ $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.80.2 0.0.0.0 UG0 0 0 eth0 10.0.0.0 192.168.80.1 255.255.255.0 UG0 0 0 eth0 192.168.80.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 But this does not work either. I don't get any ping response. On the host system I get immediate response...

Yep - what's the result of 'route print' or 'netstat -r' there? Also, you need to make sure that there's no conflict (i.e. the 192.168.x.x range isn't routed elsewhere there). Also, when trying to sort it out, I'd try pinging from both sides. I assume that 'ping 192.168.80.1' works on the host machine, right (i.e. the virtual interface is up)? If so, would pinging 192.168.80.130 work from that side? Finally - not sure what you meant by the reference to the 'VPN network', but if your machine is connected to a VPN (external), you need to make sure that the VPN client isn't configured to disable all other connectivity.
