Ubuntu Networking :: Make An Application Use Ppp0 Exclusively?
May 18, 2011
I'm running 10.10 64 bit. I have a vpn service and I'd like to configure my bittorrent client to use only the vpn link (and NOT continue through my plain-old ISP service if the vpn drops). I imagine there are a few possible approaches to this:
1.have a script that checks if ppp0 is up an terminates the bt client if not
2.configure the bt client to use only ppp0 (though I tried this with qtorrent and it switches over to eth0 if vpn drops...)

internet works with MTU=1460 for ppp0. I set this up manually using ifconfig. What changes are required so that it is done by default when PPP0 connects or at boot?

I'm a n00b with these things so be nice please XD I have recently touched on this in previous posts but never came to actually trying to fix it. I have a D-Link DSL-2640R router, with dhcp disabled. It is connected to my computer via ethernet. I have the network manager configuration set to manual with an address of 192.168.1.2, Mask 255.255.255.0 and the gateway column is blank. I would like to know why my eth0 interface seems to stop me browsing.
I use a T-Mobile HUAWEI usb mobile broadband stick, Model E1750 for internet access. If anyone has any ideas as to why this is happening please discuss them. I have also tried editing the /etc/sysctl.conf file and uncommented the net.ipv4.ip_forward=1 line to enable ipv4 packet forwarding. This has not solved my problem.

I just setup a SuSE 11.3/64 server and I am trying to setup pptpd for a vpn. I noticed thatg the ppp0 (or any pppx) interface is non-exoisting and I think that that is the problem why my gre packages are not being sent by pptpd (as I have checked all other options). I have tcp port 1723, and protocol port 47 (gre) open on the firewall (SuSEfirewall2). I have traced the responses using tcpdump and only when the server sends gre to the remote client, the client never receives it (the 1723 connection is established). I checked the old server (SuSE 10.2) that worked the vpn fine, and the only thing missing on 11.3 is ppp0. All other hardware (routers, etc.) are the same. I suspect that pptpd tries to use ppp0 and the interface is non-existing. I can remotely ssh to the server, dns works, samba works, everything else works. Is it something I am missing? How do I create if ppp0 and link it to eth3, the internet gateway?
As always, a windoze tech crashed the old server and I had to setup the new one in a hurry, just before going on vacation, and people want this done by yesterday? They paid $$$$ to the windoze tech (who said Linux is obsolete) even after he almost brought the company down!

My machine has Ubuntu 10.4, installed a week ago. I'm connecting to the Internet with a Wireless 3G modem, the interface is named ppp0. Additionally, I have a network card that is connected to a home router, that's eth0. Everything works fine with eth0 disabled, all my apps can access the internet correctly. But, my issue is that when i enable eth0, i can't access the internet with any app.
So why do i need eth0 anyway? The thing is that i must share my internet connection with my sister, who is also connected to our home router. I planned to give her access by installing squid on this machine and configuring her browser to connect to squid. However, since none of my apps can connect to the internet while eth0 is active (whereas squid and all other apps work fine with eth0 disabled) I can't let her connect to squid while squid is working correctly.BTW selecting "use this connection only for resources on its network" under "routes..." of the ipv4 tab of "Auto Ethernet" made it a little better. Firefox and Xchat started to work with eth0 active. Squid still doesn't work though (althought it works just fine with eth0 disabled)

I am running a CentOS 5.6 as a Virtual Machine on my Laptop. And, to connect to internet I am using a datacard (usb modem) device (Tata Photon +).
Now, internet is working well on my VM through interface ppp0
The problem is that when I start my interface eth0, internet (running through ppp0) stops.

I have a pppoe adsl connection. When I disconnect and try to reconnect, network-manager keeps asking for my password. I type it again and again with no success. When I reboot, it works again. On ubuntu, I use pppoeconf and it works well. So on Fedora I made a connection with pppoe-setup but neither ifup nor
Code:
pppoe-connect
commands work. When I type
Code:
pppoe-connect
, it says
Code:
/usr/sbin/adsl-start: line 217: 13409 Terminated $CONNECT
"$@" > /dev/null 2>&1
. When I type
Ifup ppp0 doesn't work either. However, with exactly the same settings, ubuntu connects to the internet.

I currently have my computer connected to my main monitor, as well as my TV. I am using the Nvidia Driver and they are running as separate X screens. I have currently run into the problem that if my wife is watching videos on the TV while I am surfing the web or something on the other monitor, we really need 2 seperate cursors.Is there some way to have each X screen own a seperate cursor controlled exclusively by its own mouse? Or is there some other solution to this that anyone can think of?

Coming from Debian Sid and KDE, I am used to K3b and the problems during verify. Now with Fedora 11 and Brasero I'm also getting errors:
BraseroReadom stderr: Error trying to open /dev/sr0 exclusively (Device or resource busy)... giving up.
BraseroReadom stderr: WARNING: /dev/sr0 seems to be mounted!
BraseroReadom stderr: readom: Device or resource busy. Cannot open '/dev/sr0'. Cannot open SCSI driver.
[code].....
After going back and adding my user to cdrom and other groups, changing authorizations et.al., I am still getting errors that I don't have permissions to use the drive. I've read through forums and bug reports and find out that my problem isn't unique. Like with K3B, does the failure during verify usually leave me with a good burn anyway? Does anyone know of a gui burner that doesn't have the verify problem? Or, should I go back to burning on cli with wodim?

I just installed Ubuntu 10.04 on my laptop, and am amazed how well everything is working, even on my dual-monitor setup! But, I also have a problem with said setup. I downloaded and installed the XBMC media center, but whenever I open up the application, it displays across both monitors. Since my two monitors are of different sizes and at different heights, it looks really bad. Is there a way to always force it to load on just one monitor?

I'm a beginner to Ubuntu so this is probably an easy question, but: I installed a windows application using Wine and that worked, it launched the application just fine. But now after restarting the computer I can't see how to run that application again. It would be nice to make a desktop icon for it.

I have installed and setup 3G which works perfectly fine. I use sakis3g scripts for connecting to 3G network. My VPN profile created with network manager (client/NetworkManager GUI) works well.

Now when I do the same with using using ppp0 (which is after connecting to VPN) I get the following error messages. #cnetworkmanager --activate-connection=user,'XXXXX_vpn_singapore',ppp0,&

I am in serious situation involving PPTP protocol VPN in Debian 8 Jessie stable. I recently became a paid VPN subscriber. Using PPTP; Is there a way to automatically route all traffic through ppp0? Im getting the vpn service killed (ip address goes back to normal unmasked state) whenever there is a power outage (modem reset) and there are alot of those where I live, Im going to get astabilizer and I need a software solution for the situation as well. Theres gotta be a way to route all traffic through the VPN route ppp0 . I tried adding persist and maxfail 0 to the pptp config file but it did not do what i wanted.
Here's my peer configuration file :
pty "pptp blabla.net --nolaunchpppd"
name blablabla
password blablabla
remotename PPTP
file /etc/ppp/options.pptp
require-mppe-128
refuse-eap noauth
persist
maxfail 0
On a second note, its clear to add that I basically need a way to also auto load the line
pppd call blabla.net
and
route add default dev ppp0
On system startup by default so the computer does not use "Wired" connection ^at all^ when not through ppp0. Any other way of not losing VPN anonymity ever due to hardware malfunction.
Is there a way to do this? Ive looked on the net and everything seems like its either from the nineties or can fry my pc , Im no debian expert, less than a year at linux..
Need it to use wired only if ppp0 is being used so if its no vpn, no connection at all period,

I want to make specific keymaps for application, that working only in it and doesn't affect other apps.
For example, I already use my Caps key to toggle input language (via xorg.conf), but I want Capslock to behave like Esc in vim.
Looks like xmodmap doesn't have any options related to that.

Is it possible to create a loadable module for a C app that could be loaded into the app in runtime from a CLI or web interface?I would like the code to handle a particular type of structure to be "swappable" for lack of a better term. This would allow different modules to be used based on the users wants without having to mess with code. A different module could be downloaded into the application directory then loaded. Basicaly the code would be handed a pointer process it then return it.

Consider that I am building my application in Linux shell using make command but somehow the build fails. Is there any way I can find out that the build has failed (of course looking at shell for error messages will do the job for me but I don't want that). Is there any flag make or shell will set/reset if such failure occurs ?

i cannot seem to find a proper way to make Java my default application to open .jar files. I just made a new Debian 8.3 install on my laptop HP Pavilion G6 and the default application for opening .jar files is the Archive Manager. But when i go to "Open with.." section on right-clicking the .jar file, i get no JRE or JDK option to choose. I just installed the openjdk 7. I can manually run them from the bash, but it would be much more convenient if i just double-clicked it. Here is what i get when i run several commands in the bash :
1) which java ->Code: Select all /usr/lib/jvm/java-7-openjdk-amd64/bin/java
2) java -version -> Code: Select alljava version "1.7.0_95"
OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-1~deb8u1)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)
3) echo $PATH: Code: Select all/usr/lib/jvm/java-7-openjdk-amd64/bin:/usr/lib/jvm/java-1.7.0-openjdk-amd64/bin: /usr/local/ sbin:/usr/local/bin:/ usr/ sbin:/usr/bin:/ sbin:/bin
4) javac -version : Code: Select alljavac 1.7.0_95
