Networking :: Suse 11.3 Missing Ppp0 Interface
Oct 28, 2010
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 They paid $$$$ to the windoze tech (who said Linux is obsolete) even after he almost brought the company down!

I am reporting various network statistics in a c++ program by reading the values out of /proc. However, I am having trouble determining the link status. In particular, I am wondering:
1. How are the standard interface flags (IFF_UP, IFF_RUNNING) as referenced in if.h accessed from user land? The ifconfig man page lists its files as
/proc/net/socket (doesn't exist in suse), /proc/net/dev, and /proc/net/if_inet6. None of these seem to contain these flags.
2. ip link show reports a "NO-CARRIER" flag. How does this correlate with the "UP" and/or "RUNNING" flags as reported by ifconfig, and how is it accessed from user space?

I have already tried reloading the drivers, restarting the interface (which is missing) and every other solution I found on this forum (well... not exactly all of them but many of them) uname -a gives Linux hostname 2.6.35-27-generic #48-Ubuntu SMP Tue Feb 22 20:25:46 UTC 2011 x86_64 GNU/Linux

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.

my problem is i have setup 2x ppp used for adsl to split local and international bandwidth ppp0 is using the international account and ppp1 is using the local only account this all works fine but every so often i notice when i do an ifconfig that ppp0 is dialed up on the local account and ppp1 is dialed up on the international one, and sometimes a reboot fixes it and sometimes it doesnt
my config files are the following:
# Default ADSL network config file, as used by redhat
USERCTL=yes
PEERDNS=no
TYPE=xDSL

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...)

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.

[root@kick ~]# ip route show

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)

New Suse 11.3 installation with Gnome desktop. Added K3B using Yast2, and after completing the install of K3B, there is no icon for K3B! Instead there is an "X" and the text for K3B in it.From the main menu -> more applications -> multimedia, is where the K3B icon is.Yast2 is supposed to install any dependencies needed or warn if it can not find any missing dependencies. What is missing, or is it a permission problem? All the other application icons seem fine.

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 just converted my physical Suse 11 desktop to a virtural machine on an ESX 4.0 server. The machine boots, but there is no GUI interface, as there is one on the physical machine. How do I start GUI from the command line interface?

I have set up nagios on Suse 11.2 and it is working fine on the localhost. I can access localhost/nagios, <ipaddress>/nagios in the browser and it loads up the nagios webinterface. If I try on a computer on the network with <ipaddress>/nagios the request times out. I have tested that I can ping to and from both machines (nagios machine and the machine I am trying to access the interface from).Some detailsNagios is running in a hyper-v VM. I installed it through yast2. Communication is run via a switch and sonicwall firewall but firewall has allow all within the network.I have a feeling it's some apache2 setting that I haven't configured or something blocking port 80.

I'm loving FC14, but I just find out that Wireshark is not working, as it was on FC13.Here is what's happening..... When running the application I get prompt for authentication, that was fine under FC13. I used to type my super user password, andthat was it. On FC14 I get nothing.Now when I skip the authentication the Wireshark Gui comes up, but it has no interfaces showing on my list.What I have!:
wireshark-gnome-1.4.1-2.fc14.i686
wireshark-1.4.1-2.fc14.i686
wireshark-devel-1.4.1-2.fc14.i686

I am in need of finding out the physical interface corresponds to eth0,eth1,eth2., As similar like the lscfg command which is available in the AIX operating system. The output given below got it from AIX OS.
$ lscfg -l ent*
ent2 U787B.001.DNWFFC6-P1-T9 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent3 U787B.001.DNWFFC6-P1-T10 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent0 U787B.001.DNWFFC6-P1-C4-T1 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent1 U787B.001.DNWFFC6-P1-C4-T2 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
Is there any utility/commands available to find out the physical interface ?

I tried out the 10.04 beta in VirtualBox, and the tab for Interface in Appearance Settings was gone. This tab allowed you to edit the appearance of Toolbars in Ubuntu. You could edit whether Icons showed up in the toolbar buttons and whether Text shows up beside it. This is kind of a minor annoyance for me; is there any way to edit this option outside of the appearance settings? I'm sure there is (like editing some config file or GConf), but I'm not sure where.

I'm using handbrake to encode some dvd's and am trying to use the autoshutdown feature. It does not work.However, handbrake does not seem at fault here. When I check in qdbusviewer, there is indeed no shutdown method in the org.freedesktop.PowerManagement interface. This does not seem normal, although I have the same problem on 2 suse 11.3 boxes.Through this post, I started fiddling with policykit settings, but it doesn't change anything.Does anyone know a solution to this problem? Do you have these canShutdown/shutdown methods?

I'm having trouble getting my Ubuntu 10.04 machine (Sony Vaio VGN-SR490) to connect to the Internet by way of an Ethernet cable connected directly to my router.
I'm able to connect to the Internet using this same cable using a Windows machine, so there's something wrong with the way Linux is configured.
How do I got about figuring out what the problem is and solving it?
Here are my network settings on Linux:
$ ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
[Code].....
It looks like the network adapters list is empty. I will now install both Windows XP and Ubuntu Linux dual-boot. I'm still not able to access the internet, even through Windows. I'm wonder if this could be a hardware problem with the computer or a problem with the router itself. Other computers can connect to this same router, and work fine. (That's how I'm posting this after all!)

recently I have installed a suse 10 sp2 on my computer. I have a big problem about connecting to my ADSL Router. The problem is that I can't ping the router at all and the Kinternet log is prompted that
status is: disconnected
trying to connect to smpppd
connect to smpppd
Status is: disconnected
error: cannot read real interface for eth-bus-pci-0000:04:00.0
I can easily open the web page of my router with windows OS but in the suse I can not do that with firefox.

My Lenovo laptop has an Intel Pro 4965 Wifi adapter,here is the "lspci" detection:
03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)
So installed the needed "firmware-iwlwifi" kernel module, which is a correct kernel module for this adapter.
Then "modprobe -a iwlwifi"........no complaints !
However,
#iwconfig wlan0
wlan0 No such device
and
# lsmod |grep iwlwifi
iwlwifi 87219 0
cfg80211 350041 4 iwl4965,iwlwifi,iwlegacy,mac80211
The wired ethernet is working fine
ifconfig -a

when I go to "Preferences" "Network Connection" ' "Add" "WI-FI" "Create" "Device MAC Address " box is empty.......no Wi-Fi adapter detected !!!

I installed openSuSE 11.2 sometime ago in a COMPAQ Presario CQ60-419WM laptop (the ones that Wal-mart sold for $300 about a year-and-a-half ago. I installed the 64-bit version because I saw that the processor could support that (perhaps that was not a good idea). I have some problems that seem related to not having the necessary drivers. My wireless has never worked and my display is far from what I would like it to be (the response is slow, if a drag a window, its motion is jerky, if I scroll down in a browser window, the motion is wavy). The look and feel is very different from what I get at work and I do not know how to fix it.
