• Start script on network connect

  - by Nate Mara

  I am trying to get a GNU/Linux Bash script to run as soon as a network connection is established on my Raspberry Pi. I tried following the instructions on several pages: I have tried adding my script to /etc/network/if-up.d and running sudo chmod ugo+x on the file. I have tried adding the line post-up <path/to/script.sh> to /etc/network/interfaces I am really quite clueless here. More info: The script runs fine when manually run, here it is: http://pastebin.com/UJvt5HYU (I did remove my personal info (email addresses, passwords), but other than that, the script is unchanged. This script also uses the sendEmail program (can be found at http://caspian.dotconf.net/menu/Software/SendEmail/).

• Viewing CHM Files Across The Network in Windows 7

  - by Lukas Cenovsky

  When I try to open .chm help from a network shared drive I receive the following error: Navigation to the webpage was canceled. I know about the .reg solution described on KB896054 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions] "MaxAllowedZone"=dword:00000001 but it does not work in Windows 7. Any ideas how to make .chm help available from the network drives? Edit: I have the network path mapped to P: drive letter. My program runs from P: and I want to see the help for it. Copying the program to local drive is not a solution for me.

• network timeout how to analyse problem

  - by elhombre

  In the last three month I was experiencing that my internet connection started to get very slow and websites had long time to load. The first thing I made was an ping to www.google.com which showed that I was loosing pakets. Here some of the results: 64 bytes from 74.125.39.103: icmp_seq=2909 ttl=53 time=48.222 ms Request timeout for icmp_seq 2910 Request timeout for icmp_seq 2911 64 bytes from 74.125.39.103: icmp_seq=2912 ttl=53 time=44.372 ms Days later I had to reset my router because it wasn't able to establish a correct network connection. It was after the reset when things worked again for some days. But later the same network timeouts started to happen again. I would like to know how I can analyze the problem to get to the source which is causing this timeouts. Which steps do you take to circle in this Problem? My Network Laptop - Wireless Router modem - ISP EDIT: I am on a Mac OS X 10.6

• Auto-detect proxy settings on network

  - by Ali Lown

  I am having problems trying to run web browser software on the local network through the proxy. When running off the profile drive which is on a network share, the system is unable to auto-detect proxy settings. When running off the local C drive, the browsers are able to correctly autodetect the settings. The error from the browser is about it being unable to fetch the proxy configuration file. Is this some form of authentication preventing it retreiving the settings when running of the network location? PS. Would this be better off on superuser?

• Using Zebra LP 2844-Z over the network

  - by Jason Kealey

  Hello, I am looking for a network-based label printer. I am looking at this Zebra LP-2844-Z printer. Unfortunately, it does not come with a network interface like the lower-end LP 2824 Plus. The ZebraNet 10/100 Print Server is both expensive for what it does (~$600) and only seems to support wireless networking, not wired. I prefer wired for reliability. Questions: Can I use a cheaper off-the-shelf print server to turn the LP-2844Z to a network printer. Would I get any trouble communicating with the printer via its own programming language or via OPOS? (instead of the Windows driver) Are cheaper print servers reliable? Would I be better to get another printer model that has it built in directly to avoid having issues due to the print server? What other printer would you recommend?

• an unknown ip on network

  - by Ahmed safan

  In our office we have many PCs, all of them have static IP addresses. We had a problem with one server with ip 192.168.1.10 dropping off the network occasionally. I unplugged the network cable from the server and from pinged 192.168.1.10 from another host and there was a response. I searched all PCs to see if any has such ip but i didn't found a one. I changed the server ip to fix the problem, but I still find this rogue device using 192.168.1.10 on the network -- how can I figure out what it is? Could it be the ip of virtual machine on someone's PC?

• Windows 7 loses access to network drives

  - by dubRun

  Ok this is an odd one, but is happening often enough its getting quite annoying. I recently installed Windows 7 on my work computer (about 2 months ago) and every so often I lose access to network shares on our work network. Its one server in particular - other shares are still working fine. I have a number of folders mapped as a drive, and all of the ones on a particular file server have lost access. If I try to access the machine directly (\fileserver\d$) it doesn't work either with this message: Windows cannot access \fileserver\d$. You do not have permission to access \fileserver\d$. Contact your network administrator to request access Once I reboot the computer, access is restored like it should be. The computers are all on a domain and my user has administrator level access to the server in question.

• Creating a Network link between 2 buildings

  - by Adam

  Hey My company needs to create a network link between two buildings. Currently we have a cat5e network in one building and would like to connect some computers(about 15) in our second building to the main network in the first building. The distance between the two buildings is 30 metres. The 30 metres means going through a wall from the first building. Going through the car park and then through a wall into the other building. We can run any cables through speed ramps and so we do not need to dig up the road! Also the second building does not have an Internet connection and so we have to create some sort of cable link so that they can share our Internet connection. Ideas? Should we just run cat5e? Should we run fibre? Should we run coaxial?

• Hide network shared folder contents from users view

  - by user1157977

  I have this folder which i need to share it out on the network to facilitate patching from another pc but yet i want to prevent users from viewing the contents of the folder, is there any solutions for this? if i hide the folder and share it out on the network, i realized that when the user do a //192.168.x.x/ from another pc , the folder contents will still be visible even if its hidden. What i wanted to achieve is that the user will be able to access folder thru the network but not able to see any files within the folder (meaning he shd see a empty folder). Is it possible???

• Shared login in a computer network?

  - by Donald

  Hi, I need to understand how a network works: Several PCs running Windows XP One server The PCs are all network connected, as well as the server. Each computer share the logins. I need to understand what happens if I take off the server. Can I still login in each PC? Is the username:passwords on the server or in each computer? My final goal is to take off the server from the network and I need to know what is the server doing. What can he be doing? Thanks.

• Persistent network share connection not working with runas

  - by binarycoder

  If I use runas /user:DOMAIN\user cmd.exe (using XP), previously mapped persistent network drives are considered unavailable. net use shows: Status Local Remote Network ------------------------------------------------------------------------------- Unavailable H: \\SERVER\SHARE Microsoft Windows Network dir H: fails with "The system cannot find the path specified.". The connection is easily revived with `NET USE H: \SERVER\SHARE': not asked for a password when I do this. What is going on? Can I make Windows safely revive this drive automatically when it is first accessed.

• Windows printing: printer works locally, but over network it can't find driver

  - by JudahGabriel

  A friend has a Epson Stylus RX500 printer. She wants to share it between her WinXP desktop and her Win7 laptop. The printer is connected direct to her WinXP desktop, and she can print fine from there. But the Win7 laptop can't print -- it can see the shared printer on the network, but it can't find a driver for it. (And looking on the web, I don't see any Win7 drivers for it.) However, if I connect the printer directly to the Win7 laptop, it works, it can print. This suggests that there is a driver for it, but for some reason, it can't find a driver when connecting to the printer over the network. My question is: if a printer works when connected directly to the machine, should it still work over the local network?

• Basic questions about network topologies

  - by laoshanlung

  I have just started learning about network topologies, but there are a lot of confusion about different types of network topologies i have learnt so far. First of all, BUS topology. If i have like 100 PCs in the same wire connected using BUS topology, and the network connection speed is 100Mbps, then each PC will have a connection of 1Mbps, right ? With the same scenario, if i connect those 100 PCs using STAR topology, then each PC will have a connection of 100Mbps ? Then with the TREE topology, i divide the system into 10 sub-system (10 tree branches) , each branch has 10 PCs, then i will have other 10 small "BUS-topology" networks each one will have a connection of 10Mbps and therefore each PC will also have 10Mbps ? And the last one is RING topology, 100 PCs, each PC will have 100Mbps connection ?

• Why are network printers not available in the Add Printer Wizard...when run over a network?

  - by Kev

  From a Windows 2003 server machine I browsed the network to an XP client (\computername in Explorer) then double-clicked Printers and Faxes and then Add Printer. In the wizard, normally the second screen asks if you want to install a local printer or a network printer. Well, in this case, it seems to assume I want a local printer, because the second screen is what would normally be the third screen if you chose local printer and clicked Next. I want to install a network printer on a remote machine for its local users. Is this not possible? If not, why not?

• Advise on a 240,000 sqft outdoor wireless network

  - by whlspacedude

  I would be very appreciative of some advice in the purchase of equipment to provide a wireless network that covers the entire area of an outdoor arena. The area is rectangular-ish in shape. 400ft wide and 600ft long. It has 6 light towers, 1 on each of the 400 foot ends and 2 on each of the 600 foot ends. I can mount on anything and spend as much money as needed. The needs of the network would be to provide access for, up to 15 wireless HD cameras with audio, and a public-wifi network. Can someone point me in the right direction as far as equipment and antennas ? I can provide any additional information that you may need.

• Downloading content greater than 2000 bytes from local network hangs in browser on Windows XP

  - by artplastika

  We have web application that runs under Tomcat in a local network. Our customers experience strange problem using this web application. Let's say Tomcat server runs on host1 and we open webapp URL in browser on host2. Any browser on host 2 starts opening page and downloading of content "hangs" for hours. We've made bunch of experiments and found that any content larger than 2000 bytes makes browser request hang. Tried in Internet Explorer 8, Opera 12, Firefox. At the same time if user opens website from internet, it works. Opening webapp from the same host1 where Tomcat is running works normally. Local network is organized with D-Link DGS-3120-48TC switch. Additional info. During experiments we've noticed XP Tweaker installed on hosts. Network settings from that tool: MTU is manually set to 1500 RWIN = 14600 Support of TCP frames larger than 64 KB is on Time to Live = 32 SACK is on

• Dropbox style folder for network drives

Is there a third party solution that does it? All clients are Windows XP and Windows 7.

• Recommendations: Good Network MFP Printer/Scanner

  - by Joeme

  Hi, We have a small office that is expanding. At the moment we have 1x HP J6424 MFP, shared using it's built in network port. It is now becoming a headache, we have daily problems with people not being able to print or scan, and jobs just sitting in the queue. Or the scanner not being detected. Sometimes people can print but not scan, sometimes scan but not print, sometimes a bit of both. We are also pretty much constantly printing or scanning, or trying to! I would like to get a laser MFP (mono is fine) which works well for scanning a printing over the network with multiple users. Althernativly any recommendations for network scanners (sheet feed and or duplex a bonus). Clients are Windows 7 and Mac. Thanks very much!

• Share files - Ubuntu 12.4 and Windows 7 - one network - password not accepted

  - by gotqn

  I have three machines - two with windows 7 and one with Ubuntu 12.4 version. There are in the same network connected by modem. The two machines shares file with no problem, but they can not see the machine with Ubuntu. On the other hand, I am able to see the share files of the windows machines from the Ubuntu's Network. When I select a folder, it wants the network password - I changed it several times in order to be sure that I am entering the correct one but in every case it says that the password is wrong. I have read some topics about files sharing between Linux and windows in which it is said that I should use samba, but is there a more easy way to do this, using the build it options?

• Applications starts very slowly from a network path

  - by Snowfox

  Hi We have a windows 2008 server which hosts the network share \\srvcompany\lib. This share contains several applications needed for the daily business. Every client/user (all win xp) has shortcuts on the desktop to these apps. We have the problem that at several (but not all) clients the apps starts very slowly. If I copy the application's programm files to a local folder then they'll start fastly. When I watch the memory usage in the task manager on such a "slow" machine while an applications starts I notice that the memory usage grows much slowier than when I start the app from a "fast" machine. But when I copy files with Windows Explorer from this share, the speed is nearly the same. I've also checked the network driver, both tested clients have the same network card with the same driver version. Has anyone an idea where or what I should check next to solve this problem? Thanks for answers.
