Debian Configuration :: Setting Kernel Variable Error. Net.ipv6.bindv6only
Jul 8, 2010
Since I got the liquorix kernel installed on my machine I got an error of setting kernel variable error. net.ipv6.bindv6only at boot time, since it wasnt a big deal I never looked further into it, but now that I had some spare time and I didnt want to see any errors on my machine I found a solution for it, with a little googling all we need to do is read the /usr/share/doc/procps/README.Debian and bingo no more error i hope this help anyone else with the same problem. I did the 3rd suggestion on that file to load the module in /etc/modules cheers.

setting up NAT and firewalling for both IPv4 and IPv6. The machine is headless, so everything must be configured via CLI. I've done all IPv4 firewall configuration writing iptables rules in a bash script so far

I'm trying to define a variable, CHAN, by dividing another variable, FREQ, by a number. FREQ is a value from a file (called header.txt). What I think I'm doing with this bit of code is reading a number from header.txt whose location is specified by the head and tails, assigning it to FREQ and then defining CHAN with bc.
Code:
#!/bin/bash
while read FREQ

I got a new laptop the other day, repartitioned it and installed Lenny. The wireless did not work. From some searching, I decided that I have the 14e4:4727 broadcom chipset. The driver I need is partially supported by the 2.6.33 kernel. I installed squeeze and downloaded the 2.6.35-7 kernel from kernel.org Then compiled it with the debian 2.6.32 kernel config file. Once it was done I installed the kernel deb files, and restarted it.
Kernel 2.6.35.7 Compiled with commands
make oldconfid
make menuconfig
export CONCURRENCY_LEVEL=2
make-kpkg clean
fakeroot make-kpkg --append-to-version "-hermes" --revision "10-5-2010" --initrd kernel_image kernel_headers
[0.433831] PCI_root PNP0A03:00: address space collision : host bridge window [mem 0xafffffff-0xdfffffff] conflicts with PCI bus 000:00 [mem 0xd0000000-0xffffffff]
And it seems to hang until I manually hold the power button to shut it down.
Before I compiled my own kernel I tried to use the liquorix-2.6.35-amd64 kernel with the same result. Am I doing something incorrectly?
Computer: DELL Inspiron m5010

Howto disable IPV6 in Lenny?
I added this line:alias ipv6 off in /etc/modprobe.d/aliases:# cat /etc/modprobe.d/aliases
# These are the standard aliases for devices and kernel drivers.
# This file does not need to be modified.
#
# Please file a bug against module-init-tools if a package needs a entry

I have been trying to change my PATH environment variable to no avail. I am using Jessie i386 with MATE. Using my .bashrc file works but not well because with subshells the modifications get repeated. I want the change to occur on login.
I tried modifying ~/.profile ~/.bash_profile /etc/profile and /etc/environment and one or two others but in no case did my change get picked up even after logging out and in again and even after rebooting. I searched the Internet and found each of the above places to make the change but they don't seem to work with Jessie.
Where do I make the necessary change?

I am runing debian-5 (lenny), the default kernel 2.6.26 was unable to start the x so i installed the new kernel linux-image-2.6.32-5-686_2.6.32-28_i386.deb, now x works, but there is problem building modules for the intel soft modem linux driver hsfmodem-7.60.00.00oem which is supplied in the modem cd by the intel company.

I have a problem with my custom kernel when I want to create the Nvidia kernel module.After this finished I installed the image and headers and created the Nvidia kernel module. Everything worked fine.However, if I remove the linux-source from my home directory then I can't create the kernel module.Even though I have the headers for the kernel installed.

I have a set of vm's with stable, testing, and sid to keep track of how things are going. When I did an apt-get dist-upgrade with squeeze last week, things seemed to OK (350 package updates) until the end. It didn't seem to like and / or was confused by a kernel dependency.
I am not too concerned yet. Because these are in vm's, I do a snapshot before any significant change. I can futz around with impunity because I have that backup.
I re-booted, and tried the apt-get dist-upgrade again with same results. I think I also tried apt-get -f install.
So I reverted to the snapshot, and will simply try again in the future. I recall that with lenny as testing, the font-desktop was really screwed up for about a period of 6 weeks.
However, just in case someone else runs into this:
1) a re-boot worked, but the failure of apt-get made me nervous enough to revert.
2) waiting for corrections has seemed to work in the past (with a single exception with a 4-disk SCSI software RAID10 update that failed to re-boot lenny successfully after what seemed to be a minor update -- that was on a real system, not a vm. I haven't gotten back to look at that.)

I decided to try and get my network ready for IPv6. All of my hosts are set up to do stateful autoconfig, I have radvd installed and working, and I can ping6 ipv6.google.com from my Ubuntu server. However, when one of the clients on the inside tries to ping6, no packets return and I get this message in the router's syslog:
Code:

I have two ethernet NIC's on my debian server. One built-in Realtek [eth0] (attached to internet), and a PCI Nvidia ethernet card [eth1] (attached to my Win7 netbook). I used this guide to setup the bridge: url. It worked when I was behind a router. But when I moved the computer in front of the router, to direct connect to the internet, the internet stopped functioning on any device that I plug into my Nvidia NIC. The name of my bridge is 'br0'. Does anyone know how to fix it, so I can route the internet to my second NIC?
My Win7 netbook displays this at an 'ipconfig' command:

I just installed Debian 6 squeeze on a P3, 632 MB RAM, 20 GB HD, and am trying to get it on-line. Ran lspci and lsusb on it (advice from another forum). Got the following results:
[Code]....
Exactly what I am trying to do: Existing network is as follows: Comcast internet to cable modem to Belkin N Wireless Router Model F5D 8236-4 v3. That router is wired to one desktop (running Windows XP)and has 4 wifi notebooks (two running Windows 7 and two running Mint 9 Isadora) and two Wii consoles running off of it. I am seeking to add another desktop to the network in another room without having to drill some holes and run about 40 feet of cable. Seems like it shouldn't take much to get the two routers to "talk" to each other so I can do this. The router I am trying to hook to it is either a Belkin F5D 9230-4 wireless router or a NetGear N150 WNR1000 v2 Wireless router.

I have a problem activating the hotspot on my debian 8. The issue is that I can't activate the hotspot to give other devices wifi connection.
I have the correct driver packages from the non-free repositories (firmware-realtek) and this service (hotspot) worked fine on distros like Ubuntu, Mint and Fedora .
I tried hostapd but it didn't work. I'm using cinnamon desktop.

I'm trying to set up a small web server with php and sqlite support. I installed lighttpd, php5, php-sqlite3 and php5-sqlite3. Then, I enabled sqlite and pdo extensions in php.ini:
extension=pdo.so
extension=sqlite.so
extension=pdo_sqlite.so
However, when I try to open a SQLite3 database from php:
$database = new SQLiteDatabase($myDB, 666, $error);
I get the following exception:
SQLiteDatabase::__construct() [sqlitedatabase.--construct]: file is encrypted or is not a database
Some readings in the net make me think that my php settings are not compatible with SQLite3 databases. Is anyone successfully working with SQLite3 databases from PHP5 under Debian? Have you any recommendations? Should I rebuild php maybe?

I am putting together a server and computer lab at my school for Standardized testing, and am planning on using debian for it. But first, i must prove to the school board that this is a possible and viable option, so right now it is one pc with 1 gig ram (Going to be the server for this experiment), and two others with around 512 mb ram.the problem with all this is, the computers in the lab cannot have hard drives, as there is some sort of licencing issue. So I need to be able to have these two testing computers boot from the server's hard drive.

I have 2 windows pc's in my home and an office computer that have my files strewn about. I wanted to have them all in one central location that keeps a backup copy, so i used an old machine to start building a file server. I installed debian 5.0 on the machine, command line interface only. I have gotten ssh working so that i can do all my work on the box from one of my windows pc's by logging in with putty.my current problem is how to easily use the box hard drive for storing my files in an easily accessible way. i'm still working on getting samba to work so that i could map the /home directory to a drive letter on my two home pc's, but i'd also like to access files from my work pc. Before i do that, though, i wanted to know if this is safe and secure to map a drive on a remote machine through the internet? Are there any other security concerns I need to be addressing by having this file server set up?

I am trying to figure out what needs to be done to automatically set read/write permissions for everyone for my proprietary USB device on system boot. I have created a udev rules file which changes the permissions for the device when it is connected, but it does not change the permissions when the system is booted with the device already connected. The file looks like this:
SUBSYSTEM=="usb_device", SYSFS{idVendor}=="our vendor id", MODE="0666"
Does something else need to be added to the rules file to make it work when the system boots with the device connected? Is there some other script which needs to be created somewhere?

Would like to know the best way (or the pros and cons of different ways) to set up Alsa. I did a search for information on how to setup alsa on my system. I found a lot of out-of-date information even on the alsa wiki. What I did finally locate was two different methods for setup, both seemed somewhat up-to-date. One method at the alsa wiki said to put part of the information in the modprobe directory in a conf file and set up certain aliases. Earlier suggestions for putting information in modprobe.conf or conf.modprobe appear to be outdated and a directory with separate files for each device and a conf extension to the files is currently used. The second method from a thread on the Debian forum said to use alsactl init, set sound levels the way you want and then use alsactl save and restore functionality. Older methods using alsaconf instead of alsactl init appear to be outdated as well. Not sure where to put the call to alsactl restore though. Didn't notice that in the documentation.In case it matters, I'm running Debian Stable and have a built-in sound card on the motherboard with AC97 compatibility. It's a Realtek ALC882.
Is there a preferred or better method for setting up alsa? Is there a good pointer to instructions that are not out-of-date somewhere? Would be very interested to hear how others set sound up on their machines. What do others recommend as best steps to do this?

New to linux in general and am having issues on setting up a Raid 1 array for two disks on an HP Proliant Microserver which I am looking to be accessible from my windows PC. I have installed the latest version of debian succesfully on a 250GB disk that came with the server. I have added 2 2TB disks which I would like to have in a RAID 1 array and to have visible from windows to store music/videos etc on. I have managed to partition the two disks to FAT32 (which I think is best) and have managed to configure the array so that it shows as active when I use cat /proc/mdstat. I have been following the steps in this article [URl]... squeeze-p2 and trying to adapt it to my situation.
I am stuck on the step to create the file systems using the mkfs command. I try mkfs.vfat /dev/md0 and it comes up with the error mkfs.vfat: command not found. I have tried mkfs -t vfat /dev/md0 and it give the error "mkfs.vfat: No such file or directory" So my question is how can I continue with the process of setting up the array? Or maybe I should be asking is it possible to set up an array with FAT32 formatted disks?

Setting up my Squeeze test box, I can't seem to get APache2 to find index.html. It keeps coming up with the initial "It works!" page.
On my Squeeze server, the /etc/apache2/httpd.conf file contains this line:
DocumentRoot /home/www_local
and that box serves the website perfectly.
On the test box, I created the /home/www_local directory and put an index.html file in it, then populated /etc/apache2/httpd.conf with exactly the same DocumentRoot line and restarted Apache. Still the same result -- Apache isn't finding my index.html file. I have grep'ed all the files in /etc/apache2 and /etc/apache2/conf.d looking for 'DocumentRoot' and it's not in any of them.

I'm intending to replace my current router (486DX2 w/16MB running FREESCO which has been faithfully working 24/7 for well over a decade) with a debian box with a bit more grunt and newer features. I'm currently setting up my iptables ruleset and am after a bit of advice re the FORWARD policy. A few example rulesets I have found set the default policy to DROP and the have two lines for each port forward, one to allow the traffic and one to direct the incoming packets to the correct machine.
iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 25 -j DNAT --to-destination 10.0.100.10:25
iptables -A FORWARD -i eth1 -p tcp --dport 25 -o eth0 -d 10.0.100.10 -m conntrack --ctstate NEW -j ACCEPT
I'm thinking of setting the default policy to ACCEPT to cut down on typing as my default INPUT policy is DROP and unless there is a valid FORWARD rule for a particular port, the packets aren't going anywhere anyway. Or have I misunderstood something. My googling returned heaps of example scripts & not much intelligent commentary. Alternatively, what do you all use to configure & maintain your debian gateways; hand rolled iptables rules, or any toolset recommendations?

I have installed the Nvidia drivers on my desktop using [URL] according to the Debian way. Everything seems to be fine except the resolution. The best it will let me choose is something like 600x480. I have searched and most of what is suggested around the web is to change xorg.conf. I have tried this using different setting suggested but nothing is working. I did not have a xorg.conf file so I created one with the setting suggested on the Debian wiki.
