I made a quick attempt\u00a0 to find a replacement board but this not practical given the age of the board and the linux build.The client\u00a0 used a small number of mainly Windows XP computers at their office to access the file server and therefore did not use the Linux server as a Print Server but rather printed directly to the TCP port under Windows. No problem at all I have built plenty of these servers for myself and other clients. I am not going\u00a0 to explain now to do a Linux build as there are plenty of HowTos on the web other than to say\u00a0 I used CentOS release 6.2 (Final) with\u00a0 Linux build 2.6.32-220.4.2.el6.i686 i686.vpn and computer repairsThe build of the hardware and linux installation went smoothly and the installation was\u00a0 completed within a week and the clients could access their data and remote VPN into the box however a problem arose.\u00a0 This is not surprising as\u00a0 there will always be something you miss given the urgency of the situationI had setup the Servers VPN settings with the following pptpd.conf file setting.#localip 192.168.0.1#remoteip 192.168.0.234-238,192.168.0.245# or#localip 192.168.0.234-238,192.168.0.245#remoteip 192.168.1.234-238,192.168.1.245option \/etc\/ppp\/options.pptpdlogwtmplocalip 192.168.2.1remoteip 192.168.2.21-25and this worked fine until I found out the client had been able to take his laptop from work to his home and print to his work printer without using the Linux computer as a print server but printing directly on port 192.168.1.49 from XP.I initially tried to setup to print via CUPS on the VPN but this proved slow and problematic so the question arose how do you expose the remote network devices directly to the local network. The answer to this is to use PROXYARP in the options.pptpd.optionsms-dns 203.0.178.191ms-wins 192.168.1.110name pptpdrefuse-paprefuse-chaprefuse-mschaprequire-mschap-v2require-mppe-128proxyarplocknobsdcompnovjnovjccompnologfdand remove the localip and remoteip settings from the pptpd.conf.Proxyarp is a way of connecting to physically separate networks as they are on the same subnet , it in effect bypasses any firewall.Now I could VPN and reach the remote IP address of the printer from the local network. You could also do this by adding a rule to the firewall but PROXYARP is definitely the easiest to implement.So all was good right? Well no unfortunately both home and office networks were managed by Billion ADSL Modem routers and which by by default use the private network 192.168.1.1 and a default gateway of 192.168.1.254 which\u00a0can give \u00a0rise to all sorts of problems..One of them is that \u00a0it turns out XP does not handle this scenario particularly well ,\u00a0 Windows 7 does, and so when the client was at home connecting remotely via his home ADSL modem router he could VPN but not surf the web and this meant\u00a0 setting the use default gateway on remote network so that all the traffic goes via your VPN.Of course the client wants to VPN using his wireless broadband stick and surf the web making his web traffic ridiculously slow.The answer to this is change to a different private network on the home address.For more information about our Linux Repairs click the link[\/et_pb_text][et_pb_sidebar _builder_version=”4.23.2″ _module_preset=”default” header_text_color=”#FFFFFF” body_text_color=”#FFFFFF” body_font_size=”14px” body_line_height=”1em” background_color=”#0C71C3″ global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_sidebar][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ module_id=”review” _builder_version=”4.21.0″ _module_preset=”default” background_color=”rgba(3,55,104,0.57)” global_colors_info=”{}”][et_pb_row _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” header_text_color=”#FFFFFF” header_3_text_color=”#FFFFFF” global_colors_info=”{}”]What our Clients Say[\/et_pb_text][et_pb_code _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”]             Posted on Google        Leki Wangdi     Trustindex verifies that the original source of the review is Google.

Perth Computer Repairs Saved My Business!I have an old CNC machine that runs on Windows XP. When the hard drive failed, I also lost access to the obsolete software that operates the machine. I wasn\u2019t in a financial position to replace the CNC\u2014and even if I was, it would\u2019ve taken at least three months to get a new one.Thankfully, I called Digby. He came to my business promptly, clearly explained the recovery process, and outlined the potential risks. Digby managed to recover the hard drive and got my CNC up and running quickly.Since then, he\u2019s also built me a new computer and is helping with other IT-related needs.Thank you, Digby\u2014your expertise and support have been invaluable!
