Networking / Re: openvpn configuration?
« on: Today at 06:39:02 pm »

  Thanks for the smbtree hint. Here is what I get when I run it:

rlimit_max: increasing rlimit_max (10000) to minimum Windows limit (16384)
_get_interfaces: Failed to retrieve interface index for 'lan1': No such file or directory
added interface lan0 ip= bcast= netmask=
added interface lan1 ip= bcast= netmask=
        \\MUSICMACHINE                  MusicMachine
         \\MAINMACHINE                   MAINMACHINE Samba Server for OS/2 based systems
                \\MAINMACHINE\IPC$              IPC Service (MAINMACHINE Samba Server for OS/2 based systems)
                \\MAINMACHINE\D                 Drive D: (JFS)
                \\MAINMACHINE\Printer           Printer

 Seems there is an error from 'get interfaces' with 'lan1'. (the TAP driver) MusicMachine is Windows 10 with several shares not shown, but do show on the drive when mounted. Not sure what to do about it. I'm guessing this may be a SAMBA config issue with multiple interfaces. Google brings up nothing on this error....

Hi Paul,

 I am using your new 2.4.7 build here on both OS/2 client and server with no issues so far. It's great being able to log on to my home network shares with ArcaMapper anywhere I can connect to the internet.

 There is one minor issue with ArcaMapper (happened with all the OpenVPN builds I've tried) - when started, on the 'Network Neighborhood' tab, all of the SAMBA machines show up, but none of the shares on them. I can mount 'All shares on server' on any of the machines and shares appear when I browse the drive mounted, but no shared folder can be mounted individually. This does not happen when I am connected directly to my LAN at home. Not a big deal, but maybe there is some setting not quite right.... need to read more about OpenVPN

 Thanks for all you do for OS/2!


 PS. - the on Hobbes doesn't have the TAP driver source in it?

  In the file found on Hobbes, in the 'another' folder, there is a good cookbook for setting up a server and client on OS/2. I gave it a shot and it works great... Paul's new build too. Now I can use ArcaMapper to access my shares remotely on my laptop. Had to set up a port forward on my router to do it....


Applications / Re: Timidity MCD install (Minstaller).
« on: October 05, 2019, 08:06:16 pm »
 Hi Martin,

  I saw your post and decided to try Timidity MCD but so far no luck playing any MIDI files. If I double click one, the WPS resets and if I right click one, then choose 'Player', the playing app starts, but hangs the WPS until I force kill the 'AB' process with Top.

  The problem with CWMM can be dealt with by editing the OS2.INI 'CWMM' keyword 'mmCLSDontCheckDrives' to include the drive letter of the drive with the MIDI files on it.

  Let us know if you get it going...


Setup & Installation / Re: And it works! DOS and WINOS2 on Thinkpad X 250!

 Right click on the session icon -> Properties, click on the 'Session' tab -> Properties, choose 'All DOS settings' and scroll down to 'DOS_UMB' and click the 'Off' button. In CONFIG.SYS the default values are set on the DOS=LOW, NOUMB line. If you ever changed that for some reason (like I did) to DOS=HIGH, UMB then DOS/Win sessions will default to using DOS_UMB=On unless you go to the properties page of each session and explicitly change it there. So it's a good idea to check for that if you are having trouble with DOS/Win sessions...

 Another thing I found on 2 of my computers is that 'DOS_UMB=off' must be set, or no DOS/Win session will work...

Hardware / Re: CUPS EPSON ET-4700 printer problems

  If you have a subscription to ArcaNoae you can use the arcanoae-sub repository. Go to ANPM, click on 'Manage' -> 'Repositories...' then 'Repository => 'Add...'. Name it what you like, the URL is: '$releasever'. Check the 'Secure Repository' box, then enter your user name and password you use to get drivers etc. at the ArcaNoae website. Restart ANPM and now you should be able to see the items on the repository....


 Finally had a chance to try this out again. I installed the R8169.OS2 driver and it worked, but still showed a max RWIN of 65536 at Also replaced the Realtek NIC with an Intel PCIe Gigabit NIC, but it too showed a max RWIN of 65536. So it seems there is some software at work throttling this? Or could it be wiring? Can the motherboard control this? Next I need to swap around the cables on the switch....

  On the ArcaNoae subscriber RPM repository, there are Epson CUPS drivers. Did you try installing those? There is no ET-4700 listed in it, but there is ET-4500 and ET-4550. Maybe one of those would work...

 Ain't no denying it!

 Can you specify 'the last stable Realtek driver'?

Are the network cards Realtek?

 Only the one I am having trouble with. The other is Intel. I think I have a plugin Intel PCIe card laying around somewhere... maybe I'll give it a try...

 Both are using the latest 32 bit MultiMac from Arca Noae. The eCS machine has also been updated with all of the current ArcaNoae drivers... I'll check the NVETH driver, thanks. <EDIT> looks like NVETH is for NVidia, not Realtek....

 Just tried the TCP Analyzer at and got a strange result. I have 2 computers running OS/2 (one eCS 2.2 with Intel NIC and one ArcaOS 5.0.4 with Realtek NIC) both attached to the same router and both have identical INETCFG.INI files. I set the RWin value on both to 128480 (MTU 1500 and MSS 1460 on both) which is the highest it can be set on our stack and be a multiple of the MSS. On the eCS computer, when I run the TCP Analyzer it shows that the Default TCP Recieve Window (RWIN) = 128480 as it should. But on the ArcaOS computer the test says it is 65534! If I change RWIN to 64240 on the ArcaOS computer, then the TCP Analyzer says it is 64240 as set. So it seems that somehow the ArcaOS computer RWIN is being throttled to 65534 when set to a higher value? Anyone have any idea what might cause this? Software, hardware? Not sure where to look....

Internet / Re: TOR and FF
« on: August 13, 2019, 12:17:42 am »
 I can use Tor and Firefox (or SeaMonkey) with any unencrypted website like http:\\ But encrypted, like https:\\ will not work. The last version I know of that worked was Firefox 17. It was reported way back then, but nothing was ever done...
