Mapping a local IP to a remote one
by Mark Rogers 29 May '15

29 May '15

I'm sure that if I could make a decent job of explaining what I mean I could Google for this but... My PC is (say) 192.168.1.10, and it can access a remote device (192.168.2.100) via a VPN. What I want to do is give my PC an extra IP address (eg 192.168.1.11) and map all network traffic to that IP address (on any port, and including broadcast traffic) to 192.168.2.100, and send any responses back. In doing so, any other PC on my LAN would be able to access the remote device as if it were local (192.168.1.11). Can I do this? (Background: In this case I have some brain-dead Windows configuration software that can only talk to devices on the LAN, so I need to make the remote device appear as if it were on the LAN. However I have had similar challenges in the past where using a local Linux box as a conduit to remote devices would have been useful.) If relevant, whilst 192.168.2.100 is not a Linux PC (it's an industrial I/O unit), I do have a Linux PC on the remote network that could form part of the tunnel if required. The key point is that I need the remote unit to appear to be on the local network, not just to be accessible from it. My Windows PC can ping (etc) the remote unit fine via the VPN itself, but the configuration software will only search for and work with devices on 192.168.1.0/24, so I need to fake it. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Hi
by John Cohen 28 May '15

28 May '15

Hi everyone, I'm a sound designer living and working in Norwich and London (I mainly do sound-post production for films/commercials) I've been using linux for a few years now, (since 2007 I think?) and recently I've built and maintain a server for our small company. Still consider myself a rookie but am trying to learn as much as I can during my spare time! Look forward to reading you all / meeting some of you at a local pub some day. Cheers, John -- John Cohen

git help
by Chris Walker 28 May '15

28 May '15

Can somebody help me with some git commands please? I have a git repo called https://github.com/tonercloud/beertent and which contains two projects, harbour-beertent and harbour-beerguide. But I want to split out harbour-beerguide into a separate repository and also if possible move harbour-beertent up a level so that beertent is empty and just leave that repo as harbour-beertent. I created a folder on my machine called beerguide_gitrepo/ and having looked at this page and run step 3 - https://help.github.com/articles/splitting-a-subfolder-out-into-a-new-repos… that folder now contains a beertent folder and that in turn now has two sub-folders harbour-beertent and harbour-beerguide. But so does beertent_gitrepo. I've done as far as step 4 but that's where I am reluctant to go any further for fear of royally screwing things up. Step 5 says I should run 'git filter-branch' but for me, it lacks clarity. As I said above, I want to remove the beertent name and just leave things named harbour-* So can anybody tell me precisely the command(s) I should type in to remove harbour-beerguide from the local beertent_gitrepo and similarly remove harbour-beertent from the local beerguide_gitrepo and remove the beertent folders completely?

Starting Nexus at Startup
by Paul Grenyer 28 May '15

28 May '15

Hi All I've got a digital ocean droplet with Sonatype's Nexus installed and I'm trying to get it to start when the droplet starts. I've followed the instructions here: https://books.sonatype.com/nexus-book/reference/install-sect-service.html and updated the properties file with these: NEXUS_HOME="/usr/local/nexus-2.11.2-06" RUN_AS_USER=nexus PIDDIR="/home/nexus" and can now start and stop the service like this: service nexus start service nexus stop I added the JAVA_HOME environment variable and added JAVAM_HOME/bin to the path for the nexus user, even though I suspect they're not needed. When I restart the droplet, nexus doesn't start. The nexus log isn't written to either. I believe I have the permissions right in /etc/inid.d: -rwxr-xr-x 1 root root 14639 May 28 01:48 /etc/init.d/nexus I've even tried adding: nexus ALL = NOPASSWD: /etc/init.d/nexus to the sudoers file, but all to no avail. I don't know where to check the log for service starts either. Can anyone help, please? -- Thanks Paul Paul Grenyer e: paul.grenyer(a)gmail.com b: paulgrenyer.blogspot.com t: pjgrenyer Have you thought what Naked Element could do for you? http://nakedelement.co.uk/ It's time to get technical: http://norfolkdevelopers.com

Port Forwarding with Apache
by Paul Grenyer 04 May '15

04 May '15

Hi All I'm frustrated because this is something I have done several times, have working in production and am not able to do again. I suspect there's a piece of understanding I'm missing. I've installed Apache on a Digital Ocean, Ubuntu droplet: aptitude install apache2 a2enmod proxy a2enmod proxy_http service apache2 restart And configured it to forward to port 8938: nano /etc/apache2/apache2.conf <VirtualHost *:80> ServerAdmin paul(a)nakedelement.co.uk ServerName solr.nakedelement.co.uk ServerAlias solr ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPreserveHost on ProxyPass / http://localhost:8983/ ProxyPassReverse / http://localhost:8983/ </VirtualHost> service apache2 restart However, when I go to the droplet in the browser I get a 404. I have an existing droplet which is configured in exactly the same way and when and I access it in a browser via its IP address I get a 404, which is odd, because if I access it via solr.nakedelement.co.uk it works and the url just points to the IP address. I've tried the obvious thing of removing ServerName and restarting Apache, but there's not change. What am I not understanding? -- Thanks Paul Paul Grenyer e: paul.grenyer(a)gmail.com b: paulgrenyer.blogspot.com t: pjgrenyer Have you thought what Naked Element could do for you? http://nakedelement.co.uk/ It's time to get technical: http://norfolkdevelopers.com

Clocks
by Chris Walker 01 May '15

01 May '15

Hello, My machine seems to be having problems with its clock. Linux keeps resetting the RTC to minus one hour. The desktop is currently showing the time as 10:46 for example. If I run timedatectl, it shows this :- Local time: Wed 2015-04-29 11:43:59 BST Universal time: Wed 2015-04-29 10:43:59 UTC RTC time: Wed 2015-04-29 10:43:59 Time zone: Europe/London (BST, +0100) NTP enabled: yes NTP synchronized: no RTC in local TZ: no DST active: yes Last DST change: DST began at Sun 2015-03-29 00:59:59 GMT Sun 2015-03-29 02:00:00 BST Next DST change: DST ends (the clock jumps one hour backwards) at Sun 2015-10-25 01:59:59 BST Sun 2015-10-25 01:00:00 GMT Just before I booted into linux (the machine dual boots between Mageia 5 and Windows 7) I set the time in the BIOS to be 11:43 but I see that it's changed already. Does anybody have any ideas what's going wrong, and more importantly how to fix it? -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

"Router" distros
by Mark Rogers 30 Apr '15

30 Apr '15

In our office we have relatively poor ADSL connectivity (4-6 Mbps - I know some people here have far worse though). We currently have two ADSL lines linked together via a Draytek router and do OK. However I'd like to think about adding a third line and that goes beyond what the Draytek can do. So I'd like suggestions for Linux distros which could replace the Draytek and do some half decent load balancing (and possibly caching for eg Linux and Windows updates etc) across multiple connections. It would need to be able to handle a number of VPN connections too (PPTP unfortunately but that's determined by the other end points). I'm not interested in rolling my own - it needs to "just work" in the way that the Draytek does. ClearOS and pfSense are on my radar although I have no experience of either. Any other suggestions or advice? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

External HDD
by Anthony Anson 30 Apr '15

30 Apr '15

Bought a 500 Gig SATA drive and a portable enclosure to corral it, the idea being to install the latest Mint on it, and update Thunderguts and Firefox (or whatever it's called this week), then transfer what I want from the drive in my MSi notebook. I plug in the USB connections and a pretty blue light comeson, the drive is spinning, but there is no sign of it where there should be. True, I haven't played with the jumpers yet, but surely, there ought to be *some* acknowledgement that there's a drive there? And what number has Mint reached? I'm running 14 at present, and I have a feeling that it's a bit too long in the tooth... -- Tony http://www.girolle.co.uk/
