Dear All, I have a "iptables script file" which I copied from the net that work for years, it stopped working yesterday after I upgrade from Ubuntu 16.04 to 16.10. I am a beginner so the only way for me to diagnose the problem is to comment out line by line to see what cause the problems, my finding as follows; 482 $IPTABLES -A INPUT -i $EXTIF -s $UNIVERSE -d $EXTIP -m state --state \ 483 ESTABLISHED,RELATED -j ACCEPT error message; Bad argument `state' offending line; 527 $IPTABLES -A OUTPUT -o $INTIF -s $EXTIP -d $INTNET -j ACCEPT error message; Bad argument `192.168.0.0/24' offending line; 542 $IPTABLES -A OUTPUT -o $EXTIF -s $EXTIP -d $UNIVERSE -j ACCEPT error message; Bad argument `0.0.0.0/0' offending line; 592 $IPTABLES -t nat -A POSTROUTING -o $EXTIF -j SNAT --to $EXTIP error message; iptables v1.6.0: option "--to" requires an argument Also, variables INTNET=”192.168.0.0/24” and UNIVERSE=”0.0.0.0/0” I have searched the net for answers but most of them indicate something like "miss typing" etc. However, as the file work fine up to Ubuntu 16.04 (I have not touch the file in any way) so something must have changed in 16.10 and I am out of ideas. Thanks in advance for the assistance! Best regards, Victor Mong I am a beginner so the

Open source 3D printers for sale (used)
by Jesse Stevens 25 Oct '16

25 Oct '16

Hey folks, As you may have seen in another thread discussing finding new homes for hardware, we're looking to sell off cheaply our little 3D printers as we haven't used them for over a year now. We know we have 4 of them, but we're currently searching our storage shed for the cases with 2 of them (2 are immediately available). The reason we're listing them here on this mailing list is because these printers are Printrbot Jr 3D printers, that utilise the RepRap "Marlin" firmware (open), and the design is somewhat open (I'm a little confused as I believe when we purchased them the design was fully open, but I see here that it's a creative commons license of some sort here: http://printrbot.com/2014/03/17/printrbot-jr-v2-files-are-available-non-com… Marlin firmware info (GNU v3): http://reprap.org/wiki/Marlin These Printrbot Jr printers are well kept (serviced by us often when in use) and we got great use out of them. They fold down so that they can fit inside a briefcase. We used them primarily with education, demonstrations, and touring/residencies because of the small form factor, and ease of accessing the mechanisms (vital when you're in a remote area). Because they use the very popular open Marlin RepRap firmware you can use many different software slicers, but we used "Slic3r" to slice, and "Pronterface" to print with (we only use Linux so these tools worked well under Linux). We have had for the past couple of years 3 x Makerbot Replicator 2 printers that we primarily use so the Printrbot Jr's don't get touched much anymore. For those in the know, here are some details: Filament type: PLA Filament diameter: 1.75mm Firmware: Marlin Nozzle Diameter: 0.4mm Upgrades: Fans, removable fan mount, and power plugs (PWM controlled onboard) Maximum print size: 150mm x 100mm x 100mm Included with each printer: 1 x Printrbot Jr 3D printer 1 x Reel roller (made by Printrbot) 1 x Wooden filament reel (made by Printrbot) 1 x Plastic reel that fits roller (small amount of filament on it) 1 x Fan upgrade 1 x Power supply and IEC lead 1 x USB cable We'd be looking for $400 for each of them (4 in total) as they're in very serviceable condition and print very well (I think we got them for around $700 each originally plus the fan add ons and accessories etc). Let me know if you need to know more info (or to see pictures), we're based around Ballarat, but travel to Melbourne a couple of times a week so we'd be happy to drop it off if you're not too far away, or meet somewhere in Melbourne. Many thanks, Jesse

Correct place to list free hardware
by Jesse Stevens 25 Oct '16

25 Oct '16

Hey folks, Gosh it's been a long time since I've interacted on the mailing lists! I'm unsure where or how I should list free hardware for people - I work in the arts (am an artist) and I have access to heaps of free computers that were quite high powered just a couple of years ago, as well as quite a few Apples of various ages. I know that there is a hardware library of some sort (is that still current?) but I was wondering if there was a place where people list hardware for others to take/use? It seems I'm increasingly inundated with free hardware lately, but honestly I'm fine with the machines I have and don't want to take on any more computers (I only have 2 hands!). Jesse

making vim work properly - or other editor
by Russell Coker 20 Oct '16

20 Oct '16

I run Debian/Unstable on my laptop because I'm a DD and it helps to test all the new software. The new version of VIM has just been added, and I don't like it. By default it uses it's own copy/paste mechanism and doesn't seem to support the system clipboard. What I want is to have VIM not really know about the system clipboard and just use a middle-button click to paste with my Xterm (Konsole in this case) and have VIM just take the text. Is it possible to do this with the new version of VIM? What are other good programmers editors? I want something that will preserve white-space so it doesn't generate ridiculous diffs (no converting tabs to spaces or spaces to tabs). -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Internode + Nodephone + Asterisk (+FreePBX?)
by Michael Schams 18 Oct '16

18 Oct '16

Hi there, We are planning to switch from a standard phone line to Nodephone VoIP from Internode. I am very keen to test if Asterisk (maybe in combination with FreePBX) is an option for a small team (one trunk, 6 to 8 endpoints, all with various SIP clients). I successfully set up Asterisk 13 and pjsip and FreePBX 13 on a pretty standard Debian 8 box. I suspect the challenges start when it comes to the VoIP SIP details for the trunk. I came across a few forum posts and discussions about the Internode settings, but I wonder if anyone from the LUV community runs such a setup or has some experience with Asterisk and Internode (especially their Nodephone product)? As I pointed out above, we don't have the line yet, so it's more curiosity than a specific problem I want to solve (yet) :-) Any feedback is welcome. Cheers Michael

While ZFS has been totally reliable in preserving data I have had ongoing problems with filesystems not mounting when they should. I don't trust ZFS to be reliable as a root filesystem, I want my ZFS systems to allow me to login and run "zfs mount -a" if necessary. > (this is, of courtse, one of the reasons I dislike journald. logs should be > plain text, so you can access them without specialised tools. and rsyslogd > wasn't running in the semi-broken recovery mode that systemd dumped me in > after making me wait 1m30s until it finished doing mysterious things > (AFAICT, it was doing nothing except twiddling some stars on screen). I agree that those things need to be improved. There should be a way to get to a root login while the 90 second wait is happening. There should be an easy and obvious way to display those binary logs from the system when it's not running systemd or from another system (IE logs copied from another system). -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Stop using it!
