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 just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.
The hardware, Printer HP Photosmart C309g-m Search HP Australia - Results - 'c309g-m' ADSL wireless router D-Link DSL-G604T/AU V.B3,D-Link Support Resources latest firmware installed.The problem,After setting up to print using wireless access, printing works fine, there is however no longer any internet access available, wired or wireless ( from PCLOS, Mandriva, openSUSE, win7, or whatever!) To restore internet access requires rebooting the router and turning off the printer (or disabling its networking) similar issues with wired network printing.
My network connection breaks almost every day. I don't know whose this problem - is it my system or my provider. Everything goes ok until some moment when network disappears and ping my gateway returns "Unreachable host". In that situation I usually plug out cable and plug it in again - now network works.
I wounder if there is a way to do something from console which has the same effect as plugging out/in cable? Or may be more preferred way - can I know what exactly doesn't work when network disappears? What i must repair? May be it save me from reconnecting cable
My WiFi can connect to internet without any problem, until I plug my ethernet cable ...then I lose internet.
So the question is : how do I configure my ip/dns and stuff to still have internet when I'm plugged by cable at the same time! it was working on windows ;-)
I am using Nokia x2-00 phone. I am able to connect to the EDGE/GPRS using Blueman. However, if I use the USB cable along with KNetworkManager with the same dialing number and APN I am unable to connect. What might be the cause?
Linux box could act as a router? I have one machine running ubuntu, another running windows 7, a cable modem and a switch. Is it posible to share the connection between both computers by making the linux box a "router"?
I am using ububntu 9.10,and have a cable modem internet connection. All I have is an ethernet cable given to me,and when plugged in a windows machine and fire a browser am redirected to default login page where i can login, but when i plug it into my linux machine,i cant get the same done. In network connections it doesnt shows my autoeth0, i have deleted my existing dsl settings(not autoeth0),made a new wired network,i doubt what should i put into MAC addrs field(i have put my machines mac given by lshw -c network.) What should I put in DHCP client id? Anyways when i click on network connections it says under my wired connections-device not configured properly.
I have a CentOS system running. I want to get mail off it to my yahoo account.
I did a test mailx command and it goes out of the queue but never gets to my yahoo mail.
I am using a cable modem. I can go out to the Internet so I know I have a valid connection. I am guessing I need to set something up so the cable company will relay my mail for me.
I know i can pull pop mail down and sen it using my account.
Do I need to configure something in the sendmail.cf file to do this?
I just went into my email and say this ...patial msg included...

I have been testing with "Add a physical serial port in Polled Mode to a VM using a Null Modem cable".I have been using HP ILOM for a while and need u guys help with "can I Connect the null modem serial cable from server port to the desktop which act as a terminal through ilom?
Just today I installed opensuse 11.3 on my Compaq CQ61. Even though I am able to connect to networks (both with an ethernet cable and wireless) I don't have internet access. I have used opensuse for a very brief period in the past and I had no such problem.
I am writing a simple script which will transmit files over a serial connection. I have simplified the setup to test the solution, so the final configuration will be a bit more complicated.
Current setup: 1. 2 RS232 com ports connected with a null modem in between. 2. Open minicom on both 3. Put in 19200,8,N,1 as parameters 4. Open text travels both ways 5. Files sent over Zmodem transfer well.
Both serial adapters are USB, but I tried it also with real com ports, and same story. For simplicity, I will call one adapter "receiving" and the other "sending" to signify from which side I want to send the files through zmodem.
Then I close minicom on the "sending" site without reseting the port (I have also tried setting everything up with stty)
On sending site:
Code:
I tried googling but no solution helps. Please do not try to suggest to use minicom on both sides, because this is going to be an unattended process in the end.
How to transfer a file with zmodem using rz and sz without minicom.
Ubuntu and Xubuntu read my Motorola Surfboard SBV5120 cable modem via USB "out of the box"; Puppy LInux doesn't. The computer I've run them on doesn't support ethernet, so it has to be via USB. what can I do to get Puppy online?
I cannot connect my Dell Inspiron 1300 through the NetworkManager "wired" connection, when I try to go direct to the cable modem. It fails to connect.
If I connect the cable modem to my (linksys WRT54GS) wireless router, and then connect my laptop to a wired port in the router, it connects in seconds, successfully.
This has happened to me 2 other times, when I tried to connect my laptop to a client's cable modem, because my client did not have a wireless router available, in their home.
My wireless works fine. This has me perplexed. I'm using Ubuntu 10.04 LTS and NetworkManager Applet 0.8
I've tried some things to see what is going on, such as "ifconfig" "dhclient" as well as modifying the "Auto eth0" parameters and adding my laptop's MAC address, etc. Results were no fix or solution. I feel like I'm headed down the wrong road. Would someone set me straight? I have a feeling this is simpler than I think.
Do I have to actually reset my own or someone's cable modem to get this to work? I don't want to do that unless there's no other way. Is there? Let me know what commands I can or should run.
Running 2.6.29-gentoo-r1 on a Sun Ultrasparc 10 with a Sun Happy Meal on eth0 connected directly to my cable modem. Intermittently, with a frequency between a few hours and a few days, I lose internet connectivity. Running ifconfig eth0 indicates all is well and I have a valid IP address but I cannot even ping the cable modem's management address; pings to 127.0.0.1 and eth0's IP address do get a reply but no other address I've tried does. I can 'fix' the problem by issuing

If I check the CM logs, it appears that it has rebooted itself prior to the loss of connectivity. The strange thing is that the incoming traffic doesn't seem to be affected by this, my PSAD log is full of incoming scans even during the periods when I can't connect to the net. I suspect this is an ISP problem (they own the CM);
Running Gentoo with kernel 2.6.29 on a Sparc Ultra 10. I'm having problems with my cable modem connection failing, so I've added a static route that enables me to log into the modem's diagnostics page at 192.168.100.1 when the connection drops; my /etc/conf.d/net looks like this (with the comment lines removed).
Right now I am using some software to emulate a null modem serial cable on my Windows computer connected to itself. For development purposes I need to have a null modem connection to a linux computer from a windows host. Is there any method of doing this virtually?
i'm having problems connecting to the internet unless i manually enter the IP info.
automatic DHCP does not work. I'm on a dual boot machine vista/ubuntu 10.04 LTS connecting to the internet through a lynksys wireless g router and a cable modem.
I snaptic installed xmacro. I do not see it show up anywhere. Lost. I need a macro that can record keystrokes to reset my cable/router modem combo. I now use autohotkey. But I cannot virtual machine this, because it would need to raise up a ms windows explorer, something that cannot be done in a virtual machine on guest OS.
My broadband internet connection came with a Nokia-Seimens C2110 Adsl modem. Please help me connect the modem through USB cable as the ethernet card is used to connect my computer(Asus- P5RD2 VM motherboard) to a different computer on LAN. I am in a fix and have no clue how to proceed.
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'm running suse 11.2 and using a ZTE mf627. thus far i can connect to the internet using usb_switcher/vwdial but i want to share it across a LAN. all the how-to's on connection sharing I've seen use the network manager/network settings, but the device doesn't show up in either
I'm trying a long time to configure my 3g modem to connect.I had tryied using the KDE Network manager and the modem stay in "Waiting authorization" for ever ^^.The KDE Network manager runs ok in Kubuntu.I had tryied download and install kppp, but kppp don't open my modem (/dev/ttyUSB01)Then how can I configure my modem?
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.
