I'm actually preparing a little storage server for implementing using the Bacula suite and as I'm using only wireless connections I've been trying to find useful console applications/methods to manage wireless connections of the two laptops I'm planning to use.(besides NetworkManager cause I need to save as much disk space as I can and NetworkManager has a lot of dependences to install) that could allow me to create and use profiles for different wireless connections when moving through different places?
Actually I need the wireless adapter to connect to the AP, so both of the ethernet card should be disabled. Infact, when I try to access to the AP I must disable the eth0 card by using (sudo ifconfig eth0 down), otherwise the route assigns the default gw (192.168.1.1) to the eth0 device and the network is useless.
In the past I've used ddclient to update my zoneedit dynamic dns. Unfortunately, this seems to be broken at the moment. I've submitted a separate thread related to that problem.
What other alternatives are there to ddclient? I'm particularly interested in something that works with zoneedit.com. I'm aware of:
inadyn inadyn-mt
Inadyn is available in ubuntu. So far I have not gotten it to work but I have not tried too hard yet either.
I just switched to opensuse from fedora. So far, I like it a lot (KDE FTW). However, I am having a couple issues concerning hibernation and restarting.Whenever I merely close my computer but don't shut it off, I am forced to reboot. When I open the computer after closing it, everything stays black and nothing seems to work aside from a restart (no good, I know).When I restart, network management is disabled and thus I am prevented from accessing wireless. The only solution I have found is to hibernate, which for some reason fixes the problem. A restart however does nothing. So I guess I have two questions:1) Why can't I close my computer without turning it off?2) Is there a more permanent solution aside from merely hibernating after a crash that will fix network manager
I've just installed Fedora this morning. In the past I've tried OpenSuse and Ubuntu. OpenSuse has it's problems and I don't like Ubuntu's new "Unity" GUI, so I wanted to try something else.
1. I got my first error about 1 minute after loading, when I tried to do a software update.("could not add package update for fedora-release-rawhide-15-3(noarch)updates: fedora-release-rawhide-15-3.noarch"). Not sure what that's about, but I found a solution on these forums (just using yum update on the command line).
2. My wireless card (Realtek) is not working. It took me ages (days) to figure out how to get it to work in OpenSuse. I had to compile the driver from source and install the firmware. I'm trying to do the same in Fedora, but am getting an error I don't understand.
On OpenSuse I had to install "Linux Kernel Development", "C/C++ Development" and "Base Development" from YaST, then compile using "make" on the command line. In Fedora I've installed gcc gcc-c++, kernel-devel and kernel-headers using yum. When I try and make the file, I get the following error:
[Code]....
3. I can't find any kind of software management tool in Fedora, just the yum thing on the command line. I don't mind that, but how do I know the names of the things I want to install? Is there some way I can search for software or something?
I've been using Ubuntu since 2006, and love it! I've even gotten a few others hooked when their Windows machines crapped out due to viruses or other problems. And Ubuntu has only gotten better.Now I'm trying to build a home network around a wireless router (Linksys). I'm set up with a desktop wired to the router, and two laptops regularly connect wirelessly. The wireless router is connected to a cable modem. Everything works fine (except getting the Ubuntu laptop to connect wirelessly using WPA).
What I would like to do is use the desktop as a server, so I can see who is connected at any given time, control security protocol, edit the MAC address list, boot off unwanted users, etc. I can do most of this by connecting to 192.168.1.1, but would prefer something on the desktop. Looking through the Software Center, the only thing I can find is KontrolPack. Anyone use this? Will this give me the functions I want?
I recently upgraded from Lucid to Maverick, and I noticed that a new error message caused by a "cp" command call, including the hard links option. Fortunately, I kept the last Lucid kernel (2.6.32-25), so I could check the different behavior with booting successively on each kernel. Here are my configuration files:
On the server (192.168.1.2): /etc/fstab : UUID=... /mnt/Backup ext4 defaults,errors=remount-ro,relatime,async 0 2 /etc/exports :
[code]....
If I check permissions of /net/Backup/Folder2 from the client, I get :
- under kernel 2.6.35-22: all the subdirectories are created, but all empty; moreover, I get as many messages as number of files from the source:
"cp: cannot create the link ...: operation not allowed"
I can copy manually any file to /net/Backup/Folder2 from the client. Why the behavior has changed from kernel 2.6.32-25 to kernel 2.6.35-22 ? Should I modify the permissions or the way the mount is exported with options like "(no_)root_squash", "all_squash", or "anonuid", "anongid" ?
On my netbook, I'm experimenting with removing any panels or window navigators completely, and using synapse for launching applications. But I've encountered a quite annoying problem, as the only stable solution I've found for connecting to wireless applications is the applet used in the gnome panel. I've tried the Wicd Network Manager, but it keeps disconnecting without reason.
Is there another program for connecting wireless, or maybe a way to use applets without a panel/window navigator?
I am Network Administrator in a Degree College managing around 2500 Comps. My ISP has terminated its Internet link (15 Mbps) to our Linux Server (Installed 2 NIC) from where Internet connection is extended to rest of the machines in network. I am supposed to send different bandwidth to different departments say 5 Mbps to Hostel, 2 Mbps to Staff room etc. I am new to linux and don't know anything about Bandwidth Management in linux.
We are planing to Replace our Windoz Desktops to Linux.So, I am searching for an open source software apart from spacewalk that can install a software or a patch in all the systems that are under my network simultaneously.
i wanted to do bandwidth management/traffic shaping on my Internet link(have two internet connections), but i have some questions to ask: I want to know how could i for example filter some traffics using tc and iptables (e.g Peer-to-Peer,IM,Download Managers,Flash videos..) i can do filtering for known services like http,ssh,... but since these applications doesn't use one port, i am confused a little bit. I also want to do some bandwidth allocations (based on protocol) thats why i need filtering.
The other question is that currently i am using tc for bandwidth allocation and iptables for marking packets to send to these classes, am i doing it right? I mean it does work, but is it better to use for example "U32" filters for filtering? P.S: i tried to use ClearOS in gateway mode, but it doesn't have bandwidth allocation functionality. Does anyone know if i could do bandwidth allocation in ClearOS/Endian.
for quite a while inside of our organization we've been editing /etc/sysconfig/iptables directly without much issues. However it was suggested to us that by doing so we risk losing all those rules whenever some package decides to use lokkit or "system-config-firewal*"Doing a bit of analysis I can't really find any trace of code that would prevent us from maintaining iptables just the way we were (as long as *we* don't use lokkit or system-config-firewall*) since "service iptables save" is a valid technique and uses iptables-save script which is part of iptables package and *not* part of system-config-firewall*
So we've got some evidence that may confirm our usage as valid, however it would be nice to know if indeed this is *not* a recommended way of maintaining iptables and we should reconsider how we approach it.
How to set download limit using SQUID? I want to specify the download limit for a particular list in MB. Is it possible to limit bandwith for some group of machines in network?
I am trying to do my graduation project, it's labeled under "linux secure router", and I should build a linux based router equipped with firewall and ACL management...Some people advice me to use linux ubuntu distribution todo this I try to do that but I don't know where to start form
I enabled D-Link (DSL-502T) router web management (I am aware of security implication). I was able remotely to login to the router (by typing http://23.45.xx.6y) before changing the default number 80. Then I changed the port number from the default value 80 to 21908 (https option is not available) for better security, and when I tried to login to the router by typing this :
http://23.45.xx.6y:21908
Yes I am aware that if I am physically near to the router then I can check that , but this is not the case with me. How can I make sure that I had changed port number form 80 to 21908? Does NMAP do a trick to reveal which port is used for web management ? or are there other better options?
How can I start a program from tty1 console text mode to be executed in tty2 console text mode? Actualy I would like to start a program (chat client cli program) in tty8 automaticaly when linux PC boots.
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 am trying to do some bandwidth management testing, so I have developed a small script for doing so. When I try to run it it gives the error <error> RTNETLINK answers: invalid argument</error>. I have searched the net, and so far they say it has to do something with the kernel support.
the script: <code> tc qdisc add dev eth1 root handle 1: htb tc class add dev eth1 parent 1: classid 1:1 htb rate 2mbit ceil 2mbit tc class add dev eth1 parent 1:1 classid 1:10 htb rate 600kbit ceil 2mbit prio 2 tc class add dev eth1 parent 1:1 classid 1:20 htb rate 1400kbit ceil 2mbit tc class add dev eth1 parent 1:20 classid 20:100 htb rate 700kbit ceil 2mbit prio 0 #when running this command it gives the error tc class add dev eth1 parent 1:20 classid 20:200 htb rate 700kbit ceil 2mbit pro 1 </code>
I am running this script on a virtual machine that has ubuntu 9.04 installed.
One of the PC having Ubantu gets disconnected automatically from the network.As we do in normal windows is that we get to the device manger and select the LAN card properties and check off the power management check box similarly how can be do this thing in a linux OS.
I wanted to replace Gnome by KDE, I made a fatal fault: I deleted Gnome without installing KDE previously, thus i'm in console mode. Some friends proposed me this apt-get install kde command but that does not work because I have no internet connection, how to install my key 3G Orange by using the console?
I am having with Pan and can't seem to get any love. I'm ready to just scrap Pan but I can't find an alternative.Does anyone know of anything similar that, you know, actually works?
if anyone knows of a way to be able to console in to a cell phone? I'm guessing it may be different from one cell phone to the next, but I want to console into my phone, and ftp, or tftp a copy of the OS onto my computer, and try to maybe use gedit or nano to look at the code, and play around with it. I'd like to see where the e911 code is, and create some kind of script that would alert me whenever that gps feature that is available to the cellular providers and the government.
since Americans are required to have a cell phone that is GPS capable, I would like to know if that ever gets activated. Additionally, I would also like to write scripts that would alert me if my microphone is activated.Maybe this is only possible on Droid phones since they are Unix based? Either way, you can readily buy usb cables to connect your phone to your pc to transfer pics, videos, etc. Maybe there is a way to run nmap on that cable connection to find a way to hack in?
So, are there any alternatives to X for Linux? I often hear about other DEs that run on X11 or X, but I have read here and there that there are some alternatives that have picked up a little steam lately, but I know absolutely nothing about them.
What are these alternatives and how would you go about trying them? Are there any live distros that use anything but X?
Are there other alternatives for panel/dock in ubuntu.? I'm bored with docks providing Mac feel or ubuntu panels. Is there a way i can replace my panels with something like shown in this video: URL...
