We are having a network of 7 computers and a server (Ubuntu server). The problem is, two of them are not connecting to the network. When i check the network card of these two systems, it seems working (the green light is blinking). When i replace these systems with a laptop, it connecting to the network and there is not problem at all.
View 4 RepliesI've tried two operating systems (Ubuntu 12.04 and Windows XP) two different wireless adaptors (Dell M1530 internal adaptor and Alfa USB Adaptor which I get full bars on) and tried a different Dell M1530 laptop which I'm also having issues with. I've also tried to diagnose the network with a tool, but I'm totally unable to connect to it so I'm unable to get any more information.If I try to connect to an unsecured network, it works perfectly. I'm totally stumped about this, due to the fact that I've used two different operating systems, two different adaptors and two different laptops (albeit the same brand).

And our institute uses a proxy server... when i try to ping that server it was pinging these servers but not the external servers...like security.ubuntu.com or some other site... I can access internet from my browser, but the software center is unable to download anything.
If I have two servers, one running Windows Server 2003, and one running Ubuntu 10, what would be the best way to 'map' one's drive to another? Either way is fine. They are each in a different state, and each have an external IP. I just need to do some processing on the Ubuntu server, then write the file either to its own drive, and have the web server (Windows) read it, or, have it write to the Windows HDD, and have Windows read it.

I need an IPv4 address as well. My host (running Windows 7) gets has both an IPv4 and IPv6 address listed when I run ipconfig. When I run ifconfig on the guest (running Ubuntu Server), it only lists IPv6.

openvpn --config /home/vladimir/client.ovpn
Everything seems to be OK, it connects normally without any warnings and errors, but when I try to browse the internet I see that I still use my own IP address, so VPN connection doesn't work. When I run openvpn command, it displays the following message among others:
NOTE: unable to redirect default gateway -- Cannot read current default gateway from system

View 3 Replies View RelatedSo I finally got all my parts delivered to setup a home file/backup server this week.
It's currently running Ubuntu Server and I'm using Samba to share files on my network.
The server currently has a 2TB WD Green drive in it connected to a Asus M5A78L-M
This is then connected via CAT6a to my new Gigabit switch (TP-Link TL-SG1005D).
My home desktop is then also connected to this switch and again also through CAT6a cable.
Currently when transfering files I will get a perfect 100MB/s read from the server to my Windows machine. When copying from my Windows machine to the server I get around 30/38MB/s.
I know this drive is capable is faster speeds.
I have found ftp's write speed is much closer to what my Samba read speed is so I'm going to give it a guess that is a software problem rather than hardware
(Setup routing and iptables for new VPN connection to redirect **only** ports 80 and 443) Only my goal is a bit different. I am running a headless gui-less install of Ubuntu Server 12.04 that is being used for a variety of different purposes... I would like all traffic to travel un-prohibited through my ISP except for my transmission traffic. I have a VPN i subscribe to that allows me access for which I only want to direct a single port's traffic to. I am currently using a modified version of the code from the above link. My current code is below:
#!/bin/sh
sleep 200
DEV1=eth0

connected to internet but not able to open the websites and also not able to ping client computer with server.

At one point I was able to connect to my drives but was unable to connect to the internet. But once I call the ISP they had me change setting for Ipv4 changed defualt gateway, Ip address and DNS after that I was unable to reconnect to my drives. I've done full shut downs and restarts and nothing has worked. 1 of the computers connects to the server through wifi. I also run a VPN.

View 1 Replies View RelatedI am having linking a computer to our SBS server. The computer in question is set in a warehouse on our site. We have a leased internet connection which is used on a number of different offices. The sbs-server has an IP address of 192.168.50.254 with a gateway Ip address of 192.168.50.1. The firewall on this network has an external IP of 10.50.0.37 with a gateway of 10.50.0.254 and this links to the leased line equipment. The external IP address for this network is 62.7.70.237. The PC in the warehouse has an IP address of 192.168.0.2 attached via a router to the leased line. The routers Ip address is 192.168.0.1, the external IP address is 10.50.0.55 and a gateway of 10.50.0.254. This links to the leased line and seems to have an external Ip address of 62.7.70.238. My issue is that I want the PC in the warehouse to be able to connect in some way to the SBS-Server. I cannot seem to access it via the external IP or the gateway (10.50.0.37).
View 2 Replies View RelatedJust updated to the 1.01 firmware on my DIR-815 and now it doesn't handle loopbacks anymore.
For instance, I have a dyndns address of ericnewton76.dyndns.org. This points to my router. Works fine if you're NOT within the router's internal network, ie, outside hosts can get in just fine (try it... http:// , you'll see an IIS7 welcome screen)
However, when INSIDE the network, the requests don't get connected properly, and they used to... ie, I work with code, so my svn repo is at ericnewton76.dyndns.org/svn but inside my network it doesn't connect properly anymore (whereas it used to before firmware update)
So now I wish I could back-peddle to 1.0 firmware.

The wireless locator finds the signal but won't connect.It says "ethos" and then when you click from there I don't get through. Just seems to keep looking forever, then says after 3 minutes can't connect.It could be I need a specific driver for the Ethernos wireless device, I am not sure. Further I am had a hacking where I had to change wireless settings so I may have done it myself. I am able to connect on my Windows 7 wireless network account but not the Linux one. I tried deleting the account on the Linux Ubuntu that shows up but this didn't work.May have made worse.Is this on my wireless device side, meaning I need to change/get password ect or the Ubuntu side where it's some type of common problem. Do I need to access through the router web page? Incidentally that's blocked for me too.
