Networking :: Dealing With The Novatel USB760 Internal CD
Apr 18, 2011
I am using Ubuntu 10.04 and trying to get a Novatel USB760 to work. Initially,it is detected as a CD rather than a modem. So, I wrote a udev rule to eject it and that worked, but sometimes the CD comes back and remounts itself and then kicks the modem off and the connection dies. I tried various ways to fix this, but no luck. Finally, I just deleted all the cd files in the /etc/udev/rules.d and the /lib/udev/rules.d (if you don't delete these, udev recreates the files in /etc/udev/rules.d). That does work and now the cd reports hardware errors and does not mount and the modem works as it should.
Now, this works on the device that does not and never will have a CD or DVD attached to it, but on my laptop I don't want to do that as I would not have access to my DVD drive. Does anyone know of a way to make the udev rules ignore specific hardware and not try to create mounts or symbolic links for those devices. Ideally, I would like to blacklist the novatel CD part and not the modem, but I am unsure how or if this is possible.
I am running FC11 and I recently purchased an internet stick from Bell Canada.I have searched/googled and searched again for setup help, to no avail.When, I insert the USB Internet stick, it shows up on my computer as a MMC storage device.FYI, the light on the Stick is green, which would indicate all systems go, but it simply won't connect.
Finally, my mobile broadband is native to Fedora. Just finished clean install of FC11 and it found the device, started it, and it works, just like it did in WIndows. ZeroConfig FTW! Great job Fedora team on this. FC10 it didn't work at all and FC6, 7, and 8 it took a lot of tinkering to make it fully functional.Also, NM is working MUCH better now with static IPs over the previous FC10 version. Set it up first run and had no issues with running my laptop on the network.
I have a Novatel 760 broadband USB device and I use kppp to connect though it is extremely slow (ping takes 100ms). What I need is a way to make kppp connect on reboot without any interaction from the user. I have looked on the Internet, but I did not find anything useful. I am using kppp because I could not get gnome-ppp to connect and it does not seem to have the features of kppp.
How do I installed a sprint novatel 3g modem? I see sprint under the mobile broadband tab when I create a new connection, and it shows all the right information, but I never can connect.
What can you do when your linux system "can't find" dynamically linked libraries that are indeed installed in their correct locations? Case in point, I'm trying to run a program called 'ucanvcam':
oliver@human ~/installed/ucanvcam-0.1.6/bin $ ./ucanvcam ./ucanvcam: error while loading shared libraries: libgd.so.2: cannot open shared object file: No such file or directory oliver@human ~/installed/ucanvcam-0.1.6/bin $ locate libgd.so.2 /usr/lib64/libgd.so.2.0.0 /usr/lib64/libgd.so.2
oliver@human ~/installed/ucanvcam-0.1.6/bin $ ldd ./ucanvcam linux-gate.so.1 => (0xf7706000) [...] libgd.so.2 => not found [...] librt.so.1 => /lib32/librt.so.1 (0xf6b1e000)
How can I tell it to look for libgd.so.2 in /usr/lib64? And more importantly, why isn't it looking there, and where is it looking?
I am having trouble with a script that is supposed to : a)take all the jpg pictures in a given directory/parameter and create thumbnails of it in a directory on the desktop.
e.g from /here/are/the/files.jpg to ~/Desktop/parser-the/files.png. this is my script: all the individual parts work but it falls apart when i put them together.
Code: for picturesource in $(ls ${1}/*.[jJ][pP][gG]) do echo this is the picturesource $picturesource; destination=~/Desktop/parser-"${picturesource}"; echo this is the destination $destination;
My notebook's LCD runs at 1920x1080 while my external LCD runs at 1920x1200. For the most part I use the external LCD, but there are times when I need to disconnect and use just the notebook's LCD. Because of the different resolutions I need to exit my X session and go back in otherwise the higher resolution of the external LCD gets cut off when I switch to the notebook's LCD. Other than forcing a non-native 1920x1080 on the external LCD, is there any other way to get both screens to show the full desktop without having to restart X? The GPU I have is an nVidia with the nVidia drivers.
On my Mac, I use Text wrangler to store all of my html and css code I use to create my web site. So far so good, or should I say so great because I love using Textwrangler. My problem is that when I am aay from my computer or on another computer with another OS, I can't use Textwrangler. I am looking for a way (and I hope this is possible), to store and edit my code online no matter where I am or what computer I am using.

I have a laptop. At home and at the office I hook it up to an extra monitor for extra screen space. When I do this I add some panels on the second monitor.
When I occasionaly use my laptop op the train, all my extra panels show up on my first screen, which get really cluttered.
If I delete the panels I have to recreate them when I connect my extra screen again.
Is there any way of configuring gnome so that you can easily recreate 'deleted' panels, or configure the extra panels to not show up unless the second screen is attatched ('lock panel to screen')?
I currently work within an RTOS environment without an MMU and thus have access to the entire memory map of whatever application I'm working on. As is common in the embedded world, different parts of the memory map relate to different peripherals or different types of memory. For our next generation hardware, my company is looking at moving to an MMU-enabled processor and using Linux in some shape or form. Most of us in the dept are familiar with Linux, but we are not Linux gurus by any means. So how to explicitly indicate to Linux that we need certain portions of an application to be stored in NVRam and other portions of the application to NOT be based in NVRam has us confused. None of us have a clear understanding of how user memory is delved out by Linux and how we can influence Linux to use specific portions of the memory map at specific times.
For example in this new application, we expect to have 2 memory chips, both that are DDR3 interfaces. One is a standard DDR3 chip. The other is a non-volatile MRAM with a DDR3 interface so it can be accessed by a DDR3 controller and coexist with conventional DDR3 memory. But because the portion of the memory map that the MRAM will represent will be the only portion of non-volatile memory, we are unclear how we explicitly access MRAM addresses in an MMU-controlled environment. My hail-mary guess was that we would want to somehow tell Linux that we want the MRAM's memory space to be mounted as a RAM Drive and then we access that memory as though it is a file on a HD, except it is much higher speed since it will be at DDR3/MRAM speeds. Is there a better, more straight forward way to do this? Coming from an RTOS world, Linux is going to pose some serious challenges for us, but I think it will be the right move once we are all up to speed and are thinking Linux-centric.
I am trying to extend my LVM and didn't feel like dealing with the terminal commands, so I downloaded system-config-lvm. But when I run it, I get the following readout:
Code: sudo system-config-lvm Traceback (most recent call last): File "/usr/share/system-config-lvm/system-config-lvm.py", line 50, in <module> from Volume_Tab_View import Volume_Tab_View File "/usr/share/system-config-lvm/Volume_Tab_View.py", line 11, in <module> from Properties_Renderer import Properties_Renderer
I just purchased a Verizon USB 760 Modem.I purchased the Modem from Verizon because their web site stated that it supported all major OS including Linux.
My system specs are: HP Compaq 6715b Laptop
OS Information OS: Linux 2.6.25.20-0.4-default i686 Current user: jraglin@Jada System: openSUSE 11.0 (i586)
I have two NASes. I work off of one, and the other is used as a backup. As I have it set up now, it's slow. Running a backup takes a week. Even for 7 TB, with 1,979,407 files, this seems a bit outlandish,particularly as both systems are RAID-5 and the network is all gigabit. I've been digging about in the rsync man pages, and I really don't understand what differentiates the various topologies.Right now, all the processing is being done on the backup NAS, which has the main volume from the main NAS mounted locally over SMB. I suspect that the SMB overhead is killing me, particularly when dealing with lots of files.
I think what I need is to set up rsync on the main nas as a daemon, and then run a local rsync client to connect to it, which would hopefully allow me to completely avoid the whole SMB-in-the-middle affair, but aside from mentioning that it's there, I can find very little information on why one would want to use the daemon mode for rsync.
Here's my current rsync command line: rsync -r -progress --delete /cifs/Thecus/ /mnt/Storage/input? Is there a better way/tool to do this? Edit:Ok, to address the additional questions: The "Main" NAS is a Thecus N7700. I have additional modules installed that give me SSH, and it has rsync, but it's not in the $PATH, and I havn't figured out how to edit the local $PATH in a way that persists between reboots. The "Backup" NAS is a DIY affair, built around a 1.6Ghz Via Mobo with a Adaptec Hardware RAID card. It's running CentOS 5 with a full desktop environment. It's the hardware I'm running rsync from. (Gigabit is through a additional PCI card).
Further Edit: Ok, got rsync over SSH working (thanks, lajuette!).I had to do a bit of tweaking on my command line, I'm running rsync with the args:rsync -rum --inplace --progress --delete --rsync-path=/opt/bin/rsync sys@10.1.1.10:/raid/data/Storage /mnt/Storage (Note: I'm specifically not using -a, because I want to change the ownership to the local account, to not freak-out SELinux)
It returns an error dealing just with the h264 codec saying that I need to use a vpre parameter? I can't find any documentation on using the vpre parameter.
so I have a Verizon Novatel USB760 and a Eeepc 2G web surf running Debian 6.0.2 (Squeeze) and a kernel version of 2.6.32. Now I've read a lot of other post on a lot of other forums on how to get the USB760 to work but I'm just using a command line Debian with no GUI and everything I've read so far ends up needing some graphical interface software to use, and everything else hasn't ended up working. So is there any simple way that can easily be added to some script to connect to the USB760 when I plug it in? I'll provide any further details that may be needed my goal in the long run is to get it running on a Guruplug running an updated kernel.
P.S. I'm relatively new to Linux i have some experience.
I am not too knowledgeable on networks, however I think this should be possible.I have a computer at work, which is connected to the work network. I have files stored on the central server here and also my local computer.
At this place, computer support say "We do not offer this service". However they also say "The simplest way to do what you are asking is to install an ssh server on your actual workstation".I have done this, and it the openssh server is working because I can test from my workstation by doing ssh user@hostname and it works.What I want to do however, is to connect from outside the network. Firstly, is this possible, and secondly, what is the syntax for ssh in order to do it.
I am currently working with a cloning project using FOG on Ubuntu 10.10 (Desktop). While there is certainly a learning curve, all seems to be going well.
For the initial project, I have this "cloning network" isolated completely. Meaning, it is not connected to my main network/domain switch - FOG is handling the DHCP, I have a dedicated managed switch handling the routing between the FOG server and the client clones.
The main problem I am having is that Ubuntu is not able to resolve the hostnames of the client computers.
I know this is because I do not have DNS setup on my Ubuntu PC.
What is the best route to take in order to resolve this? Can I use bind9 to take care of it, or is that too complicated for what I need it to do?
I am a new user to Linux but in the last couple of months gained some Idea about it,I am trying to set up a small network in my office having 3 windows xp PCs, two fedora10 PCsI have an adsl router with 4-port hub connecting to the internet, one switch (say sw1) and one linux PC (say linux1) is connected directly to the router, the three win xp PCs are connected to switch sw1.all the above is working fine, I am able to get connected to Internet In all the systems, and able to network among all the above four.Now I want to make the linux1 as a proxy server for, hence I added another network card into it connected it to another switch sw2, which is connected to another linux pc (say linux2).
I have tried a hundred things, and googled an equal no. and finally posting it here.In order to reduce confusion I have disabled DHCP in all machines, and given static ips insteadNetworkManager was not happy about it, hence to fix my static IP i disabled NetworkManager ('chkconfig NetworkManager off')
Everything is working fine and CLIENT A can talk to CLIENT B and vice versa, with only one problem - CLIENT A cannot ping 10.10.30.1.
I checked routing several times, there is no NAT and firewall is disabled on the SERVER.
CLIENT B can ping and access any device in the diagram. CLIENT A can ping and access any device in the diagram too, however cannot ping eth1 of SERVER (10.10.30.1). ROUTER can ping any device in the diagram except eth1 of SERVER (10.10.30.1).
If I launch 'ping 10.10.30.1' from CLIENT A and run tcpdump on SERVER eth0 I see no hits at all. If I launch 'ping 10.10.30.1' from CLIENT A and run tcpdump on SERVER eth1 I see ICMP requests coming from CLIENT A but no replies.
It doesn't look like a routing problem because clients A and B can communicate with each other. Also, we have around 20 similar installations but this is the first time CLIENT A cannot ping internal interface of SERVER.
I did a new install of Kubuntu 9.04. I use static ip addresses. In an attempt to resolve the issue with the network manger in 9.04, I removed the network manager. I am now able to set the ip addresses just fine and I get to the internet. However, for some reason, I can't get to my internal router. Has anybody encountered this or have a suggestion on what I may try?
What i wanted to do was use a linux machine with a wireless and wired interface to act as a router. The wireless interface would be the outside and get its IP via DHCP from the wireless my landlord provides. The wired connection would be for my local pcs. I understand it would be slow having multiple pcs using a single wireless gateway.
I have two boxes, 1- Centos router, 2- centos web/mail server..
When trying to receive mail using mail.xxx.xxx in the mail client server settings, it will not resolve to any machine on the internal network... I have to enter the internal IP address in the incoming and outgoing email settings..
Same with the website I host.. I have to enter the internal IP to get access..
It just will not resolve the DNS on the internal network.
How can i build an internal dns server for my network, but don't use the top level domain, e.g:. mycat.com. I want to use mycat.kgn. And I want to put a mycat.kgn mail server on the network for internal uses.
My setup: dns mx mail2.mycat.com (my server) mx mail.mycat.com (godaddy) inet-gateway & firewall & mailserver: centos 4, mail2.mycat.com nic1 - internet nic2 - 192.168.0.1 kerio email server 6
All workstation & server uses: ip: (below) netmask: 255.255.255.0 gateway: 192.168.0.1 dns: 192.168.0.1
Workstations: windows & linux nic1 - (192.168.0.20 - 192.168.0.199)
Printers: HP laserjet jetdirect (192.168.0.211 - 192.168.0.249)
Config: I need a dns server with: dns mx zimbra.mycat.kgn 192.168.0.127 A mycat.kgn 192.168.0.1 A samba.mycat.kgn 192.168.0.128 A www.mycat.kgn 192.168.0.1 NS ns1.mycat.kgn 192.168.0.129
All workstation and servers: ip: (same as above) netmask: 255.255.255.0 gateway: 192.168.0.1 dns: 192.168.0.129
ldap all machine to zimbra.mycat.kgn for login info and password. map drive g: to samba.mycat.kgn data-share (with users rights from ldap)
I tried to do this in virtualbox, but fail badly! I created 6 vm using ubuntu 804 and 910, but my dns was not getting any records with dig, so I found an howto on powerdns. But I had to use mycat.com and not mycat.kgn?
I will draw my network to be! each machine: ip: (sameas above) gateway: 192.168.0.1 dns: 192.168.0.129 dns-nameserver 192.168.0.129 nameserver 192.168.0.129 and if the dns server does not find the info it forward it to the gateway 192.168.0.1
Now I'm not too clued up about networking and IP addresses. However, I know that I have an IP address for my router (which is dynamic) and then all of my machines have internal address e.g.
192.168.0.2 192.168.0.3 etc...
My server, had the internal address of 192.168.0.4 but now has changed to 192.168.0.7 what causes this to happen? I have to change my port forwarding on my router to allow access to my server from outside my network.
Basically, i want to be able to type a domain in my browser e.g. default.dev and it direct to the ../www/default folder on the Ubuntu Server on my network. The reason being is that as a web developer i have a number of sites that i'm working on locally and i'm getting tired of adding the domain to my hosts file and then creating a virtual host in Apache - i believe this can be done with BIND - is this right? If so what steps are required?
If I try ping a host on my internal lan from my ubuntu notebook the host name never resolves, but if I ping www.domainname.xxx it will resolve because our dhcp server is setup as the dns server too. If I use the connect to server tool and select samba share and specify host by name, it can resolve that and the shares show up... same dns server, same machine, but different interface/program. My real reason behind this is because my synergy+ keeps falling over whenever the synergy servers dhcp lease expires and it gets a new I have to then specify the new address and change configs.
