Debian Configuration :: Server Missing About 300mb Of Ram
Mar 15, 2010
I downloaded the most recent version of debian and isntalled it. Everything went really well there. Until i issued free -m on the box. It would appear that the server is missing about 300mb of ram which is okay for i figured perhaps the video card / sound was taking that amount of ram for it'self. it was not until i installed Xen and I found a bigger problem with memory and my system. for what ever reason when I attempt to create a domU with 512mb of ram, i need to add 19MB more ram so that when i issue free -m from within the domU it will show a total of 512. worse yet is that when i raise the total up to 1024 for 1gb or domU ram, i need to addd 28mb or ram. and add 28mb of ram PER GB i wish to add to the domU.

I've been testing Squeeze to determine whether KDE4 is finally suitable for my primary machine. Everything seems to be working fine except for detection of IDE devices. My CD/DVD drive no longer automounts and the reason seems to be that no device is being created. My Lenny system detects the drive as /dev/hda, but no such device exists in Squeeze. During boot, Squeeze appears to detect the drive as /dev/sr0 (according to dmesg), but in fact that device does not exist either.I'm actually running the Lenny kernel, as I am unable to compile my Ralink wireless driver (rt2860sta) using the Squeeze kernel. Also, for inquiring minds, I use removable HDD drive bays on my systems to simplify testing.

So, as per Arch Linux's wiki, I tried to make some optimisations to the intel driver through setting it up in Xorg.conf (or as advised by that wiki article, in '/etc/X11/xorg.conf.d/20-intel.conf' ), but I've ran into trouble enabling DRI3. Here's my current config file:
Code: Select allSection "Device"
  Identifier "Intel Graphics"
  Driver   "intel"
  Option   "AccelMethod" "SNA"
  Option   "DRI"  "3"
  Option   "TearFree"  "true"
EndSection
So far everything works fine, I haven't seen any noticeable tearing, nor did I had any problems with any graphics-intensive programs I run, but there's a slight problem with the DRI3 part as indicated by Xorg's logs:
Code: Select all[Â Â 26.556] (II) Loading sub module "dri2"
[Â Â 26.556] (II) LoadModule: "dri2"
[Â Â 26.556] (II) Module "dri2" already built-in
[Â Â 26.556] (==) Depth 24 pixmap format is 32 bpp
[Â Â 26.616] (II) intel(0): SNA initialized with Haswell (gen7.5, gt2) backend
[Â Â 26.616] (==) intel(0): Backing store enabled
[Code] ....
First of all it still mentions the DRI2 driver, is this supposed to happen, or did something go wrong? Also it complains that it cannot find a file, which I can't figure out which package it belongs to, and taking a quick search around the interwebs hasn't produced anything useful...
The IGP is the CPU, which is actually a i5-4460... which according to Wikipedia it has a HD Graphics 4600 GPU.

I just upgraded my Debian stretch via apt-get and I noticed that the network manager is missing at least 2 icons: the mobile broadband icon and the settings icon. I haven't found any bug reports or other information about how to restore them. The icons were there after initial installation of version 8.2.0 from DVD.

Here's my problem: I'm running a Lenny laptop and I need both wifi and virtualbox to work. I had to do a kernel upgrade to run the wifi. It works with either the 2.6.29 or 2.6.30 kernels, but with 2.6.30 I'm having screen brightness issues that I can't seem to get rid of. So I want to run 2.6.29, but virtualbox is a bit of a problem because it requires linux-headers-2.6.29, but when I try to install the amd64 headers it tells me that it cannot install the dependency linux-kbuild-2.6.29. Is there any way I can get that dependency installed on my computer?

I seem to have a major discrepancy between what df reports and what du reports. df tells me that I am using 20G, but I am only able to find 9.5G using du. What follows are the ls -l of root, a df of my system, and the du for every directory in root that is not a symbolic link, mnt, or proc. I would appreciate any suggestions on where to look for the remaining 10.5G that seems to have disappeared.
I am running under VM Player code...

Added the following line to sources.list:
deb [URL] squeeze main non-free
After that I did an update and upgrade.
The following packages were kept back : ffmpeg libavcodec52 libavdevice52 libavformat52 libcairo2 libpostproc51 libswscale0 mplayer ( libcairo2 is on hold ).
To overcome this I did: apt-get install mplayer
The following extra packages will be installed:

I am trying to upgrade the version of dovecot on a rarely-maintained Debian machine with which I almost never have problems (ain't Linux wonderful?). The current version is 1.0.rc15-2, and I think the latest version is 1.2 something, but the point is that I want to be able to use the pigeonhole sieve plugin. Anyway, when I try to "apt-get install dovecot-imapd dovecot-pop3d", it gets to this: Err [URL].. etch/main gnomemeeting 2.0.3-6 404 Not Found Failed to fetch [URL]..-6_all.deb 404 Not Found E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

I have a strange problem with the ACPI in my laptop, the problem start some days ago, I don't remember exactly the day.
The first symptom is with de Gnome Power Manager, only show me when I disconnect de AC power, but when connect it again the Power Manager icon disappear and the energy battery stay in the same value.
After search for a while, all the post I read talking about the /proc/acpi/battery directory, but this directory not exist on my laptop.
I have a laptop Lenovo G460. My OS is Squeeze. My Kernel is 2.6.38-bpo.2-amd64, because the 2.6.32 version of the kernel don't recognize well my audio card.
I can't attach the dmesg and the lsmod output because I receive a message "Sorry, the board attachment quota has been reached.", both file are compressed.

so I just installed Squeeze Alpha1 amd64, dual boot with MS Vista using Grub. Everything seemed fine, but I'm apparently missing about 40GB of space. It should be set up as so:
101GB NTFS /dev/sda1 - Vista
12GB NTFS /dev/sda2 - HP Recovery
45GB ext3 /dev/sda3 - / Debian squeeze

This may sound ridiculous, but after installing Debian 5 (from CD 1) in my laptop, ASUS UL80VT, it fails to detect the Ethernet device. The device is "Atheros AR8131 PCI-E Ethernet Controller". I guess the problem comes with the old kernel of version 5. I was intending to compile the latest kernel anyway. But the problem is is there any heads up i need to download the kernel and trying to compile it? Is there anyone who uses Debian on UL80VT. If there is, does it works okay?In short I want to compile the latest kernel, hoping it will fix the Ethernet device. There are installers available with the latest kernel. But I want to do it on my own.

I've got Debian Sid x64 on my machine. Problem is that in my KDE setup several programs don't work, namely System Load Viewer plasmoid, plasmoid with temperature info and update-notifier-kde. System Load Viewer always shows 0% RAM and swap usage, as well as no processors, temperature sensors plasmoid shows no sensors available even after I installed lm-sensors and run sensors-detect, update-notifier-kde doesn't show any notifications even if I run aptitude update manualy. I might be mistaken but it seems to me that these three programs are not working because of some common reason, most likely some policy package either missing or misconfigured, but I can't figure out what is it.

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

I'm running the current release of Debian with the 2.6.26-2 kernel. This is an upgrade from an older (2.4 kernel) series redhat release. One of the things I had working in the older system was a dns server with accompanying monthly update of the root hints file. I tried working through a dns how-to to set this up again, but it seems much has moved around since I last played with this. All of the files listed in the how-to are not where it says they should be. I am looking for a better reference on keeping the dns server running with current server information.

I wanted to setup my server as a router/gateway just for educational purposes and also when it succeeded i will keep the gateway and place it on the front line right after my modem.
My current setup as it is now :
The GATEWAY/ROUTER will be doing the main work to act as a dhcp server and firewall.
Now my setup as it is now :
So now what i ment to do was :
Let the clients connect to the gateway via ETH1 and all the stuff being router to ETH0 which is the NIC that is connected to the internet.
But now i have two huge problems :
1. The DHCP configuration seems to be fine the client machines get their ip adresses and /etc/resolve.conf looks fine to. But somehow the GATEWAY/ROUTER wont let me use the specified external DNs server so i cant do anything on these machines.
2. The firewall script [url] at line 27 should be DROP but if i use this line of code the GATEWAY/ROUTER cannot use his dns server settings so when i try to browse the internet or ping a machine outside my local network it would came up with nothing.

Debian Jessie on a raspberry pi 2
I'm trying to get nfs server working at boot up and it isn't starting because it says portmapper isn't running. I've read through a bunch of documentation on this and have gotten to the point that if the documentation tells me to Code: Select all$ apt-get install nfs-kernel-server portmap I usually stop there as it is outdated. I cant find a process doc that utilizes rpcbind. So, here is what I've done on my own:
setup /etc/exports with a proper nfs dir and exportfs it
Code: Select all$ apt-get install nfs-common nfs-kernel-server
$ sysv-rc-conf
---│ nfs-kerne$ [ ]   [X]   [X]   [X]   [X]   [ ]   [ ]   [ ]    │
---│ rpcbind   [ ]   [X]   [X]   [X]   [X]   [ ]   [ ]   [ ]    │
$ service rpcbind start
[Code] ....
The errors however don't seem critical as I'm able to mount the exported directory. OK so it appears to me that nfs server is working. However through a boot, the nfs-kernel-server and the rpcbind services are not starting. The nfs-kernel-server didn't start because rpcbind wasn't running. So I start rpcbind and then nfs-kernel-server and then nfs server works. So what am I missing? Why will rpcbind not start at boot?

I'm having a lot of difficulty trying to use tab completion while working in my FTP server from a terminal.I access this server with other Linux distros and OSX and the completion works fine.

Tab completion does work for system related tasks, no problem.

With this hack the servers become visible, and i can see/connect from the outside; - but for obvious reasons ont like this solution.Anyone is able to shed some light why the server needs to do outgoing tarffic to become visible?
