OpenSUSE Network :: Resolver With Os 11.2 And Wireless Or 3g Modem (pppd)?
Feb 20, 2010
If I connect with a 3g modem or with wireless sometimes the resolving does not work. This happens on opensuse 11.2. nslookup and dig works but nor ping nor ssh nor any other network application does work If I modify the /etc/resolv.conf after connecting to a wireless network for example it does not work even the dns are known And more strange if the resolver works and I modify /etc/resolv.conf with known dns the resolver does not work anymore. BTW: the dns entry from the wireless is 192.168.1.1 and I do not have any idea how the wireless ap is configured... so it could be in this case that dns is not forwared only allowed to use 192.168.1.1 but the other case is a 3g modem which not even the propagated dns entries works in the bad case

I recently encountered an error with pppd on both openSUSE 11.2 and 11.3. I use umtsmon (which uses pppd) to connect to the internet with my 3G device. Yesterday for some reason it just plainly refused to connect to the internet. I have been using the same configuration for almost a year now without any issues. I tried it on 4 different computers running 11.2 and 11.3 and all of them failed. Thinking that it is the hardware I borrowed a windows laptop and tested it on that, only to find that it works flawlessly. On my network server I sometimes use the device as a backup and activate it with "ifup modem0", for some reason this also now fails.
After doing some troubleshooting I managed to extract the following from pppd.
Running it with my user account:
pppd options in effect:
I have no idea why pppd would break all of a sudden but I expect it might have been an update that broke it since I have automated updates on all of my systems.

I have just moved over from MS to Linux and so far I am pretty happy (couple of frustrations along the way, but nothing I could not sort out so far).
Except this little bit that has me bogged down. I am trying to get my HS2300 HSDPA wireless modem to work, but I am a little stuck here.
I found a post that I should get the HP-WMI module to load. That was a post on an older kernel and this guy mentioned that is should be included in newer versions of the kernel.
Modprobe did not deliver any results, however an "lsmod |grep wmi" delivered the following:
Obviously I need to look for hp_wmi, but so far I cannot get anything to work.

I am trying to connect to wireless broadband using SuSE 11.2 and a Huawei E160E USB modem, through Internode Australia.
Networkmanager does not seem to recognise the modem so I am trying other means. I believe I have got wvdial to connect (it reports a correct IP address, the light on the stick goes solid blue and I can ping external IP addresses). However it can't find a DNS nameserver and I can't work out how to provide one to wvdial, and therefore can't do anything through the connection (I would rather not revert to ifup because this laptop travels between WLANs). I followed swerdna's comprehensive instructions on setting up a wireless broadband modem in YAST, but I got lost on the very last instruction: KMenu --> KInternet. I can't find this on my application launcher.

I have bought a new USB modem from my service provider. The model they provided is "Huawei EC1260" Huawei Terminal. As usual the official support is for windows and mac.
I tried to install this device using two methods..
1) Set knetworkmanager settings to "traditional with ifup". Then in wireless setup there is a choice of having "usb" (A tick box). I selected that, and setup completed successfully but the knetworkmanager was not up(I did ifdown wlan0 (wlan0 was the wireless config name), ifup wlan0 and the rcnetwork restart.)
2) Again knetworkmanager was set to "traditional method with ifup. This times while adding the connection I specifically selected the type "USB", then clicked to finish the configuration. The configuration finished without any errors but when I checked the Network Configuration screen no USB device was added there.
Are there any specific steps to configure a USB modem

trying to make my 3G modem (a ZTE MF622) work with OpenSUSE 11.2. KNetworkManager is recognizing it (so I suppose it's not on Storage Mode), I can create the 3G connection and connect, but I can't navigate on any sites (ping gives "unknown host" for any IP). Also, the KNetworkManager applet doesn't show anything on fields "Name servers" and "Domains" (they are blank). Tried some instructions from the internet here and there, but didn't have any luck.

I have a devolo MicroLink 56k Fun LAN modem, which I could configure in openSuse 11.2 as an DSL device. With 11.2 it worked fine. But it isn't possible in 11.3 to configure it, because I cannot set the dial up internet provider phone number for this DSL device.I also tried it to configure it as a modem, but then it used the /dev/modem device, which is the wrong device for this LAN modem.

I have a box with 1 ethernet card and Huawei E160 USB modem. So, I have configured eth0 interface with IP 192.168.1.1 and modem0 interface with dynamically assigned IP. Now, I'd like to share Internet from modem0 to eth0 and so to the rest of home local network.
I need your advice on how to do it. All the manuals I've read deal with two ethernet cards that have static IPs. It seems that YAST lacks the GUI for it, too. Also, I need the configuration to work even with no user logged in so I'm using ifup instead of NetworkManager.

I am running a 3-G wireless USB broadband modem, and connecting with Network Manager, but I keep getting disconnected when idle after 5-6 minutes. I am used to using Kinternet to connect with my 3-G wireless USB broadband modem, and setting it up in Yast / Network / Modems, but was not able to configure my modem there (for some mysterious reason) so ended up using Network Manager instead.
What's going on here regarding YAST being unable to configure my modem (even when Network Manger is disabled). But my main problem at this point is that my connection times out after about 6 minutes if I'm idle. This is a big problem for me because I type slow and frequently get disconnected while posting on message boards. Where are the idle time out settings are for Network Manager? I can't seem to find them.

I just loaded 11.2 & Kde 4.3. Installed both Kinternet and Kppp. My modem is a USR PCI HW modem 2976. Hardware Info shows it connected to /dev/ttyS4. I configured the modem with Yast as modem0. The user access box is checked for Kinternet Both Kppp and and Kinternet will dial out.
The connect response comes back from the ISP and either of the dialers will hang and the dial tone comes back. The firewall is showing modem0 in the External section. Nothing changes if I shut the firewall off.There's nothing in the dmesg I could find. Could this be a pppd permission problem?

My machine is running on a dual-boot Windows Vista/openSUSE 11.2 scenario. I have been trying to get my Huawei E1550 to work on Linux for the past few days trying numerous methods suggested in other forums from people with the same problem, but I have not produced any fruitful results.
Plugging in the USB modem results in Linux detecting it as a CD-ROM. I have installed usb_modeswitch in attempt to switch it to a modem, but Linux still fails to recognize it. Windows Device Manager and lsusb both give ProductID=1001 and VendorID=12d1 connected to USB1. I'm guessing since Windows detects the correct IDs, the Linux versions should also be correct. In any case, I ran usb_modeswitch with the Default IDs for /etc/usb_modeswitch.conf, which gave 0x1446 as the ProductID, not 0x1001. Upon running usb_modeswitch, the product ID could not be found so the program fails and quits asking if it's connected (and it is).
Just to test, I also ran wvdial which unsurprisingly did not detect the modem and could not send the init strings. All commands were done using root privileges. Also note that when after usb_modeswitch is run and upon plugging in the USB, NetworkManager pops up near the tray saying "attached" but still shows the device as a CD-ROM.

I have an external usb dial up modem. lsusb shows: Bus 001 Device 002: ID 2001:f10d D-Link Corp. [hex] Accent Communications Modem How do I set this up? It probably needs a driver, how do I check it, or better yet, can I get yast to tell me if it recognizes the modem or needs firmware? I know linux and dial up is like the seventh circle of hell. Just wondering if there was a snowball's chances of getting this working. Sorry if this is the wrong section to ask in. Seemed like as good as any when I checked.

I have a US Robotics serial modem, and I have smpppd enabled in system services, with wvdial and kppp installed. When I try to set the modem up using yast, I keep getting hung up by the different screens. First a screen that asks if I need to dial a number to get out. I have to dial 9, so I have that entered. Then a screen that asks for "country" and "provider."
When I try to enter anything, nothing shows in the boxes, so I go to a screen that asks for the phone number, provider, user name and password. When I enter those, it goes to a screen that wants "Connection Parameters", with default settings and the "buttons" at the bottom of the screen "muted," or flattened out, i.e. unusable. That makes it impossible for me to set the information as saved, so it's back to the beginning and sart over, with the same results over and over. How do I get the modem so it dials out?

I have a Zoom 2920 internal hardware modem that worked well with Suse 10.0. In Suse 11.3 the modem config. overview lists 2 modems for this one board; #1- AT Modem and #2- Venus Modem (v90, 56K Flex). With #1 "edit" brings up modem parameters and the modem device line is blank. With #2 the device line shows /dev/ttys4.
When the provider parameters are entered, for either #1 or #2, the modem overview continues to list them as not configured but a third line "modem 0" is configured with the provider information at /dev/ttys4. The modem will not function.

I got a new cable modem so I could get rid of the one I've been leasing from the cable company. It is a Motorola sb6120. Everything is fine with the ISP, it's approved for operation on their network, the only hitch was I had to use my Windows laptop to run their activation software.
At any rate, with the new modem installed, I hop on my Linux box and go to work. I'm seeing some terrible delays in looking up names. When I look with firebug, all the dns lookups for new names are taking 15+ seconds. First I just think maybe the names aren't cached or something is weird for a minute and it will get better, but no. After several restarts and then a couple days persevering with the new cable modem, all DNS queries are still terribly slow (including zypper, mail client, web client).
Suddenly I remember an issue I was having with, I believe version 11.1 when I first installed it. For just the computer on my network with a fixed IP address, DNS resolution was slow like this and if I disabled IPv6 then all was well. I believe there was even a patch issued back then for gethostbyname() that was supposed to fix the issue? So, when I disable IPv6, DNS lookup is back to normal. The two Linux computers on my network had been working fine with IPv6 and the old modem, though, and the Windows box is still working fine even with the new modem.
I can disable IPv6 and make it fast again, but really why should I have to?

I'm using a 'ice.net' D-50 (CDMA EV-DO rev A) mobile broadband USB modem, also sold as Cmotech CNU-680 in other areas. The modem is connected to a USB port on a hp8710w mobile workstation.
As the 11.2 Gnome Network Manager won't connect this modem to Internet (see my first post here), I have downloaded and installed a 'D50 Modem Manager program' from [url]
After unpacking and installing this cmotech-qtmodem-1.6-1.i586.rpm package for suse on 11.2 x86_64, the gui application 'D-50 Modem Manager' is found in the Internet Group.
However, neither this program does connect the D-50 modem really on 11.2 x86_64 (as it did on 11.1 x86_64). Tried both traditional network setup and with Network Manager.
Any idea and suggestion how to trobleshoot this further? I think I've seen that a newer version cmotech-qtmodem 1.9 has been mentioned on the web, but without being able to find and download this version.
Command output as follows:
As normal user:
On the Modem Manager gui: D-50 modem is ready
From Login script Debug window:
As root:
It seemed like the modem connected, but Firefox was not able to connect afterwards (Server not found)

i have been able to get on line running other linux os using the terminal first i type sudo modprobe -r usbserial & enter followed by sudo modprobe usbserial vendor=0x1199 product=0x120 & enter the last command is sudo dmesg|grep -i ttyusb. I have done this for years and it always has got me on line after the above i open kppp and select for modem /dev/ttyusb0 and click to verify kppp recognizes my sierra wireless usb modem and that is all i have ever had to do, plug in the usb modem type the three commands it comes back with confirmation the modem is attached to ttyusb0, ttyusb1 & ttyusb2 in kppp i click /dev/ttyusb0 and click quarry and get on line with suse11.1 it is not so the first command sudo modprobe -r usbserial comes back with a fatal error but the second and third command give me the same results saying i have attached the usbmodem to ttyusb0,1 & 2. but i cannot configure it in kppp.
i have tried researching on line but cannot find a similar thread. I believe the way i described above has worked on lindows 5.0, and it is how i do it with Mint which i can get on line with today. so i hope one of the wonderful millions of linux users will direct me as to what i am doing wrong. i am running amd 785 4 gb ram msi mainboard ms-7549 my modem is sierra wierless modem 595u (vendor=0x1199 product=0x120) connecting through Sprint pcs which requires no user name or password.

I had an ATT "2Wire" modem/router that was working but connection to the Internet was often poor. An ATT technician came to my home and swapped out the modem/router for the identical model. I changed the ESSID and WEP code to match the new unit and everything was fine with the following wireless units: a wireless desktop, two cellphones, three wireless Archos tablets, and a couple of e-reader tablets. So all seemed to be fine wirelessly. However...
My laptop (SuSE 11.0, KDE3) simply won't connect no matter what I do. I changed the ESSID and WEP info in the lappy exactly as was done with the other wireless devices named above. But no good. The lappy does see the modem/router (a good, strong signal appears in KNetworkManager). But it seems as if the modem/router is rejecting the lappy's attempted handshake using the new ESSID and/or WEP information.
I thought that perhaps there was something wrong with the lappy's wireless card, so I took it to a Starbucks to see if it would connect there on an open network, and it did without problem. So the lappy's wireless card appears to be working fine. It just won't talk to the encrypted modem/router at home. Here are the settings on the lappy. Hopefully something here is easily identified as the culprit. With all the clicking I've done it certainly is possible that I ticked something that should not have been ticked and just don't realize what I've done.
Network settings screen:
Global options tab:
Network setup method: user controlled with Network Manager
Change default route via DHCP (ticked)
[code]....
Why won't the new modem/router which is exactly the same as the old one except for the ESSID and WEP work with my lappy yet it does work with a bunch of other wireless devices?
