Networking :: Pon Connects Ok To Remote VPN / Cant Get Route Added Automatically
Mar 5, 2010
I have configured a VPN connection to a remote router which connects ok. I can ping the remote router IP, but cannot ping any other IP on their network.I have put this down to needing a route added. I can manually type # route add -net 192.168.1.0 netmask 255.255. 255.0 dev ppp0 and all works like I want it to, but I really need this to be automatic everytime the connection starts.I have tried following URL... but cant get it to work. The file is called /etc/ppp/ip-up.d/routing and has execution priviledges (755) so ive hit a dead end.

I am trying to connect to a windows 2000 VPN server at work, with my current settings in DOES connect to the VPN and i can ping the domain server which is 10.1.1.2 but the first issue is i cannot ping the other computers on the network(via hostnames) can't remember the ip address of the other machines . second issue is when the connection is established and i RDP into 10.1.1.2 ok great i am connected to the server but any interaction in the RDP session even moving the mouse on the screen kills the session and the VPN connection fails.
Running Ubuntu 10.04 LTS 64Bit
Image of current settings in network manager:
Syslog:
Code:
May 11 12:08:04 oliver-desktop NetworkManager: <info> Starting VPN service 'org.freedesktop.NetworkManager.pptp'...
May 11 12:08:04 oliver-desktop NetworkManager: <info> VPN service 'org.freedesktop.NetworkManager.pptp' started

I am running 10.04 and am trying to add a route to a remote network using a gateway that is NOT on the local subnet. I am not messing with the default GW as all the other posts I can find are. I am using public IP addresses, but all of this is contained behind a firewall. I need to add a route to a private network (192.168.1.x) that is behind a router attached to a different subnet. The current routing table looks like this:
Code:
Destination Gateway Genmask Flags Metric Ref Use Iface
xxx.xxx.108.48 0.0.0.0 255.255.255.240 U 1 0 0 eth0
0.0.0.0 xxx.xxx.108.49 0.0.0.0 UG 0 0 0 eth0
The remote network is 192.168.1.0/24 and it is reachable via xxx.xxx.37.203. I can ping the gateway no problem. However when I try to add a route to this network I get an error.
route add -net 192.168.1.0 netmask 255.255.255.0 gw xxx.xxx.37.203
SIOCADDRT: No such process
I assume this is because the GW is not on the local subnet. When I try this on a machine that is connected to the xxx.xxx.37 network, everything works fine and I can reach the remote network. I even tried adding a static route to the gateway, but that did not help.
route add -host xxx.xxx.37.203 gw xxx.xxx.108.49

I just recently installed Fedora 11 and I notice that the network connection will not connect automatically. Basically I am trying to get to a point where it automatically connects without anyone logged in. (I hope that makes sense) Right now I have to log in as a user in order to get eth1 to connect and get an IP.

I work from home writing web content, and need the use of an article spinner tool called "The Best spinner". It is an .exe file and I installed it in my Mint Debian edition machine using wine, and everything is fine except for one thing. The app opens out, connects to the net, and then closes automatically. In fact if I check on the internet activity, I can see the app downloading the latest version, but the problem is that always it closes within a few seconds leaving me no other choice other than to log into a windows machine to work on it.
I uninstalled and reinstalled the app a couple of times but it does not seem to have helped. It requires the .net packages in winetricks, and I read that wine does not support net very well, yet the app is installed and even connects to the net. I don't understand the underlying process of how windows apps work in wine. Any work around considering that I never log into windows for anything other than using this app, a workaround means that windows is gone forever from my life.

I have 3 network interfaces on my Linux Router :
Interface - Gateway - Type
Code:
br0 - 192.168.0.1 - Internet
eth2 - 192.168.1.1 - LAN
tun0 - 10.0.0.2 - VPN (via br0)
What I'd like to do is to route all TCP packets coming from eth2 to tun0 where a VPN client is running on 10.0.0.2. If I delete all default routes and if I add a new route to tun0 like :
Code:
route del default
route add default gw 10.0.0.2
Everything is fine, and everyone on eth2 can reach the Internet using the VPN access. Now the problem is that my VPN client does not allow any other protocols other than TCP. And I also want to allow VPN access only to eth2, no other LAN nor the router itself. use iptables to filter any TCP packets and mark them, so they can be sent to tun0, while any other packets can reach the Internet via br0 (192.168.0.1). I found on the Internet that we can mark packets before they get routed. Using the following commands :
Code:
iptables -t mangle -A PREROUTING -j MARK --set-mark 85 -i eth2 -p tcp --dport 80
ip route add table 300 default via 10.0.0.2 dev tun0
ip rule add fwmark 0x55 table 300
First of all, --dport 80 never work... :/ I wanted to filter TCP 80 packets coming from eth2, but none of them seems to be HTTP packets... oO (very strange...). Nevermind, I decided to forget about the --dport option. I use the "iptables -L -v -t mangle" command to see how many packets are marked, and it is working fine, all TCP packets coming from eth2 are marked. Now the problem is that none of them are routed to tun0 they are all respecting the "route -n" rules... and not the "table 300" rule I have created.

I need to be able to use an rsync command in script that will be run by cron. And it needs to be able to pass a password to rsync so that the remote server it's connecting to will authenticate.
I cannot set up ssh keys between the two servers, it's not an option. I cannot use any other language other than bash, it's my only option. I know this is highly insecure, I have no other option.
So far I have this:
rsync --rsh="/usr/bin/ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o PreferredAuthentications=password" -raxv /source/dir/* user@remotehost:/target/directory/.
This allows the script to ignore host verification and goes directly to the password prompt. I need the script to fill in this password prompt with the password that is stored in a variable.
I tried using expect, but I honestly don't know the syntax, it just keeps failing. A lot of the examples I'm finding online for expect starts off with a "spawn", which i don't have installed, and not sure if I have the ability to install it yet.

My understanding is that when one installs Adobe Reader the browser plugin automatically gets added. For some reason the Adobe browser plugin isn't working in Firefox on my Ubuntu 10.10 desktop. The plugin doesn't show up in Tools Add-ons or Tools -> Manage Content Plug-ins. It works fine on my laptop with the same versions of Ubuntu, Adobe Reader (9.4.2-0maverick1), and firefox (3.6.17).
Starting firefox from a terminal yields messages that are probably illuminating to some:
Code:
$ LoadPlugin: failed to initialize shared library /opt/google/picasa/3.0/lib/npPicasa3.so [/opt/google/picasa/3.0/lib/npPicasa3.so: cannot open shared object file: Permission denied]
2.4+ kernel w/o ELF notes? -- report this
*** NSPlugin Viewer *** ERROR: /opt/Adobe/Reader9/Browser/intellinux/nppdf.so: failed to map segment from shared object: Permission denied
This message caused me to stumble onto the readme file, /opt/Adobe/Reader9/Browser/HowTo/ENU/Browser_Plugin_HowTo.txt, which encouraged me to run the script /opt/Adobe/Reader9/Browser/install_browser_plugin.
I ran it in the local mode, and it created the directory ~/.mozilla/plugins and the file nppdf.so in it. Alas, it didn't work, complaining that,
Code:
$ LoadPlugin: failed to initialize shared library /home/clarkb/.mozilla/plugins/nppdf.so [/home/clarkb/.mozilla/plugins/nppdf.so: wrong ELF class: ELFCLASS32]
and again,
Code:
*** NSPlugin Viewer *** ERROR: /opt/Adobe/Reader9/Browser/intellinux/nppdf.so: failed to map segment from shared object: Permission denied
Next I removed the plugins directory I'd created, and, following an Internet hint, I tried the command:
Code:
nspluginwrapper -i /opt/Adobe/Reader9/Browser/intellinux/nppdf.so
This didn't work either, again complaining that it "failed to map segment..."
How I can get the Adobe browser plugin to work? I'm almost sure that it worked not long ago.

I have a samba shared folder in my flash disk. Yesterday I installed ubuntu 11.04 and now sharing is not working any more. I do the usual procedure (that worked so far), I right click my folder > sharing options and tick "share this folder" as well as "Allow others to create and delete files in this folder" but I dont get the usual messages asking to add permissions automatically.When I try to mount my folder in another pc with linux, I get permission denied and that the folder is only readable and in another, windows cannot find the network path to my folder.My folder has about 10.000 files. asking to add permissions automaticallyI created another folder on the same flash and when I create share I get the message asking to add permissions automatically but it is not visible either. I even cant see my folder in "my places" > network, so it is not a matter of the mounting command

I would like to add a static route, however I do not understand what is meant by the Address setting below
GATEWAY2=10.241.58.62
NETMASK2=255.255.255.224
ADDRESS2=10.241.57.32
Does this mean any addresses beginning with 10.241.57.32 are routed over the gateway 10.241.58.62 an address range

I would like to update my network setup.
Today, I have an ADSL box which is my gateway to internet (192.168.0.1).
I have a Raspberry pi (RPI) which I use as a dhcp & dns server (192.168.0.2).
Recently my mobile phone operator installed a 4G antenna beside my home, and the bandwidth and latency are much better with my mobile phone than with my internet provider (ADSL).
I would like to install a wifi dongle on my RPI (I would get wlan0 & eth0 interfaces)
When RPI detect my shared phone connection (tethering) I would like RPI to automatically route internet:
- from authorized devices on my network to my mobile connexion (wlan0 -> mobile phone).
- from other devices to the standard ADSL internet (eth0 -> ADSL box).
I don't want any device to use the shared 4G connexion, best would be authorized devices to be selected by MAC address. How I should properly setup such a network ?

Having trouble getting my Netgear WNA1000 working thru wireless router. Have tried lots of suggestions from other threads to no avail. Someone suggested that th routing table isn't set correctly, so have been trying to use the follwing to make the proper entry in the routing table: sudo route add -net 192.168.0.1 netmask 255.255.255.0 dev wlan0
Result: error message stating with:
"route: netmask does not match route address"
followed by "Usage" instructions which tell me to do what I just did. Any ideas on how I can populate my routing table with correct entry for my wireless card? Not to complicate matters, but I temporarily turned off encryption on my router to eliminate that as a possibility until I get connected. So maybe it'still trying to connect via encrypted mode - do I need to turn off encryption on my (client) end?

I set up a tower with 11.04 desktop as a minecraft server and I would like to be able to access it from work for whatever reason.I set up RPD and checked all the necessary check boxes, opened ports (to the best of my knowledge), installed tightvnc on the remote computer and gave it a go. SUCCESS... almost. It connected and brought up the desktop as desired, however the image seems "frozen". By "frozen" I mean that I am still able to click around and do things on the server, but I just can't see what I'm doing because the remote client isn't "refreshing". It just looks like nothings happening. Example: I move the cursor to the menu bar and click on Applications. It looks like nothing happens however if I walk over to my server, the Applications menu has been clicked and has extended.
If I log out of the remote client and then reconnect I will see this on the remote box, but nothing after that.I hope this is making sense. Does anyone have any idea what could be causing this? I have tried this on two separate computers, one that is on the same network as the server (with both local IP and external IP) and the other is at work. Both do the same thing.

Another issue I'm having, considerably more serious, is my ability to connect to wifi access points with proxies. The story goes, my school has free wifi, but you have to go through their proxies to access the internet (like at McDonald's or Starbucks, where you must 'log in' and accept their usage terms). I can connect, including DHCP, and when I type in any URI I get the redirect posted to Chromium's address bar, but I simply cannot connect to it. This has happened in Ubuntu and Arch, using at least a couple different network management methods (I usually use WICD but I think I started off with networkd). The strange thing (to me) is that my Android phone works just fine, so although I'm not completely familiar with Android on this level, I don't imagine it's the fault of Linux itself. but I'll only be able to experiment with this once a week, on Saturdays (when I have class --gotta do something entertaining).

I have installed OpenVPN to use it as an internet gateway butcan't get it to work.OpenVPN installed without any problem. The client can also connect and ping the server but there is no internet traffic.I think it is because of a wrong gateway address which the client gets but I'm not sure. server IP address is 10.8.0.1 and the client can ping this IP but it's default gateway is always 10.8.0.5 which is not accessible from the client.This is my server.conf:
Code:
dev tun
proto tcp

I am using Fedora 8 on my laptop, newly installed, I can see the network card(Linksys WPc54G v2) and Network Manager sees the wireless router, however as soon as I tell it to connect my computer freezes and I have to restart. I searched for solutions but all I found was Ubuntu problems.
Actually it seems that the trigger is when the keyring comes up and asks for a password. As soon as I start typing the pass it locks.

I've got a Zotac MAG HD-ND01 with XBMC live installed. This is built on Karmic Koala and runs very nicely through the wired NIC.
I configure the box using a cable. I'm using WPA2-PSK and it is clearly authenticating OK.. It gets an IP address.. the AP shows a connection to the box. My XP laptop connects to the access point OK.. just can't connect to the box via the wireless, and it can't see the network using wireless.
I have followed a number of threads on connecting Atheros 9XXX wireless [URL] but no joy.
Also, can Ubuntu connect to the AP at any speed greater than 54MB? My windows PC connects at 144MB+ . Will ndiswrappers connect at those sorts of speeds?

Let me start by saying that I am new to ubuntu, and that I always use forums as a last resort.
I installed ubuntu 10, and immediately after the Wifi card deected my network name, and actually connected to it, but then I opened up firefox and....no internet.
Since then I have been trying to fix this problem, and after some research I found out that my card (PCI Cwp-905) is RT2760 based, and I downloaded the linux RT2760 drivers for it.
The driver folder contained a readme file with commands you should enter to install it, and other setup files.
The problem: every command I typed in didn't work. I tried "make", and then "sudo make", but just got permission denied each time. I am now at a dead end. (Please note that I changed my directory to the folder location before doing this)
Does anyone know what I am doing wrong? If you want I can attach the driver files.

My wireless connection always worked. When I log in, I already have internet access.I went on holiday and connected to several other networks.Now the laptop will not connect anymore. Sometimes after 5-10 minutes.When I forse to connect ("Connect to hidden wireless network), the laptop connects after several seconds. But not automatically.My wireless modem uses WPA2, MAC filtering and has a hidden access point.I use Ubuntu 10.4 on a HP Probook laptop. In "Network connections", under "Wireless", the "Connect Automaticly" and "Available to all users" are selected. When connected, the signal strenght is very good.

i noticed today that the last three places ive tried to use wifi at (a friends house, my cousins house, and my moms office wifi) refuse to connect, even after triple checking all the passwords and trying various security protocols (WEP 40, WEP 128, etc.). strangely, last weekend i was able to connect to a hotel wifi signal with no trouble. even stranger, my ipod touch is able to connect to all these places. at my friends house, we even tried an ethernet cable but ubuntu didnt even know it was there. im a little concerned about this, as i might need to connect to wifi for something really important and ubuntu wont cooperate.

I have an asus router running tomato firmware. Through the webGUI I have set up an openVPN server as per the tomato guides. I am using the network manager plug-in in ubuntu 10.04 to connect as a client to the tomato openVPN. All of my certificates seem to be set up and working correctly.
I am able to successfully connect to the openVPN server using the ubuntu client but after that I get nothing. On the client side I am unable to ping the router, any ip addresses inside my private network, the virtual network ip, and web browsing (client) no longer works.
Also, when connected I am unable to ping the client from the private network.
Before connecting
Code:

I got a little problem with network manager. I got two connections in it, with two different DNS-Servers, because the one of my provider is very slow I surf with opendns, but sometimes that slows down too, so I want to change if necessary. Both connections got the same fixed IP.That worked all fine, until I got my new router (it's a Netgear WGU 624). It's connected by cable and I configured it like the old one. But for some reason instead of connecting to the manually configured connections, my fedora 10 creates a new one "auto eth 0" with a dynamic IP. So every time I boot or switch on from standby my PC connects with this one and I have to manually set it to the right connection. There's no chance to edit or delete it cause those two buttons are grey and won't work. I also tried restarting network manager manually and I also tried starting it with su as root.

Got an Edimax 7717un USB dongle for my Acer aspire 6930 (built-in WiFi is broken). It finds access point OK, but fails to setup with DHCP. If I put in manual IP config, I can ping OK, but I cannot browse web (or even my router's setup page). I get same behaviour on a home brew desktop.
With manual IP config, ping to my router works fine (and very fast, as does ping to 2 or 3 internet web sites. I can traceroute to internet web sites OK as well. With web browsing, if I wait a few minutes some bits of the page may arrive. With connection set to DHCP, Wicd shows WiFi connecting OK, but DHCP setup times out.
