Ubuntu Networking :: Change Run Level For Wireless Networking?
Apr 6, 2010
I have a desktop with a printer attached on a wireless link.I have a laptop where I want to print from. The problem is the wireless link comes up only after I log on to the desktop.I would prefer the wireless link (and cups) to be up with out having to log on at the desktop.
I have been trying to test the use of X window forwarding over SSH in a cafe. The Cafe's WiFi requires login via a web browser. Using Fedora 11 with Gnome on a Dell Latitude D600 laptop, the wireless works just fine. I am able to use a virtual terminal to ssh to my server at home. NX client/server works also. However, when I change to Run Level 3 on the Laptop in order to use X Window forwarding, wireless networking fails to function. Will wireless networking function at Run Level 3, and if so, how is that accomplished? Also, if I get Wireless to work at Run Level 3, will I be able to login to the free public wifi using Lynx or some other text browser, as I can with IE and Firefox?
I got this Acer Revo 3610 nettop about a week ago. I got it to use as an htpc, and decide to do an install of xbmc live on it. I have everything set up the way I want it at this point, but I'm stuck on trying to configure the wireless.
I'm not sure where I should start troubleshooting this thing, but something about this seems off to me.
Code: xbmc@XBMCLive:~$ sudo -s root@XBMCLive:~# iwconfig ra0 mode Managed root@XBMCLive:~# iwconfig lo no wireless extensions.
I currently have a desktop PC (running 10.04) connected to the home hub (v2) via ethernet and everything works correctly. I want to change to wireless so I can move the home hub, I've tried several usb wireless adapters and always end up with the same issue. I can associate with the home hub it will hand out an ip address, answer dns queries and allow me to connect to its web setup page but not the internet (ping, web, etc). I also have a htpc (also 10.04) which is able to connect through the wireless correctly plus a laptop running XP.
Desktop - Ubuntu 10.04 (gnome) HTPC - Mythtv 10.04 Laptop - Windows XP

Hardware: Vostro 3500, BCM4353Ubuntu 10.10Today I decided to test uptime on battery. But when I started using battery I noticed that internet connection is very slow(around 1-4 KB/s, normally ~128KB/s).I used Code:iwpriv eth1 set_pm 0(pm = power mode? And what means this parameter 0, 1 and 2?)and everything seems to be ok now.And my question is - where can I edit which power mode settings for wifi are used on battery?
I've changed my wireless network password and when I try to connect through my F10 machine, it continues to use the old password. I've changed it a number of times through the GUI that pops up (Wireless Network Authentication Required) and also through the Edit Connections GUI but they always revert back to the old password and disregard the new one.
I would like to change wireless mode on my network card. When i type in iwconfig in terminal so i get abg I would like to have only a mode active. How do i do?
Is there an ink level app that works with network printers? I am currently using Ubuntu Lucid x64 with a Canon MX860 printer that was installed using this tutorial: [URL]. Everything seems to work fine (it prints) but I cannot get any of the ink level apps to work (Mtink or Inkblot). After doing some research, my conclusion is those apps only work with USB connected printers. Is that true?
I would like be able to access packets coming off the network with the hopes of coding a primitive packet sniffer for learning purposes. I would also like to be able to piece together my own packets and send them out on my network. Eventually, I would also like to write a simple firewall so I want the capability to drop packets as well as let them pass. I assume I will have to access the kernel with some system calls to do this, any one have any information or resources that could help me on this project?
Im reading this tutorial that is old(kernel 2.4) for iptables. It states that iptables should not be read at the application level of the TCP model because of packet boundaries. Does this still hold true today?
What does the Quality, Signal Level and Noise Level actually mean? Which should I be looking for when looking for good APs?Is Quality the same as RXQ in airodump?
Summary: Several school networks in need of a fairly low-level way to log network use, especially Internet. Raw packet captures are too low (and big). Turnkey solutions we've looked at (Untangle) aren't really a good fit. This seems like a common issue. Detail: For legal reasons, we have to be able to roll back time every so often (ie. when death-threats are made on some web-forum). Currently, our traffic logs on Internet traffic are pretty high-level and aren't really useful to point a finger at the guilty or away from the innocent. We also like to keep our users honest by providing them with data about their own computer use (ie. what are the top 10 websites they hit).
I've been building up rules with iptables and ulogd to log the creation of new connections and save it to a PCAP formatted file for consumption by some very simple analysis scripts, or examination with Wireshark if required. Just logging new connections prevents the logging data from getting large in a hurry, but also doesn't give us a lot of information we would like (ie. the amount of data transferred). We've been examining products that offer fairly full-featured analysis, notably Untangle, but we do a lot of weird stuff (VOIP, VC, VPNs) with traffic flowing through very minimal hardware (PC Engines) running Linux. This is very inexpensive and very flexible, and we like it that way.
I've mucked through and figured out how to mount a windows share. I can access the folders I was looking for, but the windows share was not what I thought it would be. I was looking for the specific shared folder. Instead I got a root level parent directory that included the folder I wanted, and a couple others.
smbclient -L <ipaddress> gives me a parent directory on the root
First question: Can I mount a specific folder within a share? Second question: Could somebody define share? I thought it was the specific shared folder, but that doesn't seem to be the case.
I am learning about net filters and I am practicing some sample programs on it. I am very new to this and I have a general query. I got the packet to a desired function using PRE_ROUTING hook. Now how do I frame a packet from this point? I am just trying to simulate a echo client server program in the kernel level using these hooks. Any useful info on sockets in the kernel level?
I am searching for a Linux user level command/utility to measure the network bandwitdth used by a specific process by usig its process id.i used different commands like, iperf, ntop, netstat etc, but it doesn't to meet my requirement. i need to observe network bandwidth used by only a specific process .
I need to change the default zoom level for Evince. There must be some way to do this. Besides, can Evince start without any PDF file loaded? Also, what is the command line to execute evince? (I run Linux Mint 8 based on Koala 9.10). Whenever it loads a file for which it assigns a zoom level more than 175% or 200%, the whole PC hangs if I click on the "reduce zoom" icon in the toolbar. This is a very big regression.
This is ridiculous! Even ePDFViewer is better than this. I really would like to stay with Evince for the time being, and not need to move to Foxit.
I posted earlier regarding an issue with my netbook not having the <>| keys while on Scandinavian layout (Acer Aspire One 532H). I never use the "Fn" key on any laptop I have and it's especially disposable on this Netbook. While digging around in /usr/share/kbd/keymaps/i386/qwerty I've got the fi.map.gz open but unsure as to which is the fn key. How would I find out which maps to the fn key?
A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.
I'm using a Packard Bell Easynote Tn36 laptop, and I'm having trouble with Ubuntu 10.10 and the wireless network card, (probably because of lack of driver). I.e. it is disabled.
I just upgraded to natty last night, and everything is working fine except for the network manager. I can enable and configure the wireless card via bash, but the network manager widget will not manage the wireless card.
When I first boot up, the "Enable wireless" check box is greyed out. After I enable the card via the terminal, the "Enable wireless" check box becomes ungreyed, but every time I click it, it instantly unchecks itself. I feel like Currly from the Three Stoogies. Check, uncheck, Check, uncheck.. "Slaps face repeatedly."
I have Packard Bell easynote tn36 and I used to use ubuntu 10.10 and then when I upgrad it to ubuntu 11.04 the wireless doesn't work (disable) and I can't press the botton of Enable wireless.
While playing with my Linux box, I edited rc.sysinit in /etc/rc.d/ folder. But now when I boot into run level 3 or 5, I get complain that system cannot run /etc/rc.d/rc.sysinit. I boot into run level 1, and checked its permissions, which is rw-r--r-- . It should be rwxr-xr-x. I tried to use chmod to change its permissions, but it responded that "Read Only file system" Now how can I change its persmissions when in run level 1. In run level 3 and 5, machine does not boot. My box has Fedora Core 2 with kernel 2.6.20.
