• After my laptop wakes up from sleeping/hibernating, the LCD/brightness is very low. How can I set it to default?

  - by meder

  In Power Management Preferences, On AC Power tab, I have brightness to 100%. "Dim display when idle" is not checked. I know for sure my LCD brightness is capable of going higher, because if I hit Fn and F7 then it resets the monitor brightness and settings for a few seconds, but the resolution breaks and then the brightness goes back. PS: OS is Debian Lenny ( I set the tags but for clarification ) and laptop is a Thinkpad.

• setting up a samba PDC -error with testparm

  - by Rungano

  Hi guys I have installed a samba PDC but when I test the samba configurations file I am getting errors like these, "Invalid combination of parameters for service homes. Map system can only work if create mask includes octal 010 (S_IXGRP)." My Configuration file is as follows [homes] comment = Home Directories path = /home_srv1/%u valid users = %S read only = No create mask = 0660 directory mask = 0770 browseable = No I tried to google but with no luck, Serverfault is always my best hope. Thanks for helping out.

• Setting up a transparent proxy with only one box.

  - by Scott Chamberlain

  I am playing around with transparent proxies, unfortunately I do not have two machines to test it out with. The current way I am doing things is the program makes a request to a computer on port 80, I use iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234 to redirect to my proxy that I am playing with. the proxy will send out a request to port 81 (as all outbound port 80 are being fed back in to the proxy so I want to do something like iptables -t nat -A OUTPUT -p tcp --destination-port 81 -j DNAT --to-destination xxxx:80 The problem lies with the xxxx part. How do I change the destination port without changing changing the destination ip? Or am I doing this setup completely wrong, I am learning after all and constructive criticism is definitely appreciated. The machine I am using is pretty low end so I would like not not have to create a VM with a second box unless absolutely necessary.

• running a web server with encrypted file system (all or part of it)

  - by Carlos

  Hi, I need a webserver (lamp) running inside a virtual machine (#1) running as a service (#2) in headless mode (#3) with part or the whole filesystem encrypted (#4). The virtual machine will be started with no user intervention and provide access to a web application for users in the host machine. Points #1,#2 and #3 are checked and proved to be working fine with Sun VirtualBox, so my question is for #4: Can I encrypt the all filesystem and still access the webserver (using a browser) or will grub ask me for a password? If encrypting the all filesystem is not an option, can I encrypt only /home and /var/www ? will apache/php be able to use files in /home or /var/www without asking for a password or mounting these partitions manually? Thanks

• Listing packages in a repositiory?

  - by noloader

  I'm working on Ubuntu 12.04 Server. I want to install OpenStack, so I enabled the Cloud Archive repo: sudo add-apt-repository cloud-archive:havana After the subsequent update and upgrade, I noticed python-crypto changed. python-crypto recently fixed a CVE, so I would like to ensure I'm using the patched version of python-crypto. I'd also like to compare the python-crypto in both Ubuntu and Cloud Archive. How does one list the package information for both Ubuntu::python-crypto and CloudArchive::python-crypto? (And sorry I could not tag this with apt-cache. Its not available in the list of tags). Thanks in advance

• is there a way to run a command before puppet implements a change?

  - by Patrick

  I want to have puppet run a specific command before performing any type of change. I am aware of the prerun_command option in the main puppet.conf, but this is not what I'm looking for. I want the command to only run if something is about to change, not on every puppet run. Here's the scenario. Let's say I have a bunch of web servers behind a load balancer. I then want puppet to update the web site files. But in order to prevent issues where some files have been updated, but other files haven't, and the mixed versions causing problems, I want to take the server out of the load balancer pool. I could write a script which when run will tell the load balancer to remove the box from the pool. Then puppet can do the change, and use postrun_command to put the box back in the pool once complete. But I need a way to run that script to remove the server from the pool. The only solution I can think of is to keep 2 copies of the files on the box. One a staging copy, and when puppet updates that, use a notify action to trigger the removal script, and then copy from staging into the live location. But I was hoping for something a little more generic that would work on any change being performed (upgrading a package, restarting a service, creating a user, anything).

• OpenSSH (Windows) does not forward X11

  - by Shulhi Sapli

  I'm running Ubuntu 13.04 in VM and I wanted to do X11 forwarding to my host (Win 8), so far it works fine using PuTTY and XMing server for Windows. But I am curious why it doesn't work if I use OpenSSH binaries (it comes together with Git for windows). This is what I've done so far: ssh -X [email protected] (also tried with -Y) then gedit but received error of Cannot open display. echo $DISPLAY came out as empty. So, I try to export DISPLAY=localhost:0.0 but it still won't work. The DISPLAY environment that I set is exactly as when it runs with Putty. I also try changing the DISPLAY to 192.168.2.3:0.0 and other display number as well, but still it won't work. Of course I could just use Putty to make it work, but I was wondering why OpenSSH binaries does not work. I have enabled all settings required in both /etc/ssh/ssh_config and /etc/ssh/sshd_config. If I run with -v option, this is what I get F:\SkyDrive\Projects> ssh -X -v [email protected] OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007 debug1: Connecting to 192.168.2.3 [192.168.2.3] port 22. debug1: Connection established. debug1: identity file /c/Users/Shulhi/.ssh/identity type -1 debug1: identity file /c/Users/Shulhi/.ssh/id_rsa type -1 debug1: identity file /c/Users/Shulhi/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.1p1 Debian-4 debug1: match: OpenSSH_6.1p1 Debian-4 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_4.6 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-cbc hmac-md5 none debug1: kex: client->server aes128-cbc hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host '192.168.2.3' is known and matches the RSA host key. debug1: Found key in /c/Users/Shulhi/.ssh/known_hosts:2 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Trying private key: /c/Users/Shulhi/.ssh/identity debug1: Trying private key: /c/Users/Shulhi/.ssh/id_rsa debug1: Next authentication method: password [email protected]'s password: It seems that there is no request for X11 (I'm not sure if there is should be one too here).

• Moving directories full of files over the top

  - by JavaRocky

  I took a backup of a directory which has a number directories and files inside them. Recently some files have gone missing. I would like to just move over the missing files. I prefer moving files instead of just copying as space is a premium on this particular box and the files are quite large. How can i achieve this?

• What is the best vfat driver for FUSE? (Lightweight, not mountlo)

  - by Vi

  FUSE filesystem list show some FuseFat and FatFuse. Both are old, FatFuse is read-only , FuseFat is non-buildable and probably depends on glib. Now I'm using mountlo for the task (mounting USB drives in generic way without root access or suid things (except of fusermount itself)), but it looks too big for such task. Is there good vfat FUSE driver?

• Weird nfs performance: 1 thread better than 8, 8 better than 2!

  - by Joe

  I'm trying to determine the cause of poor nfs performance between two Xen Virtual Machines (client & server) running on the same host. Specifically, the speed at which I can sequentially read a 1GB file on the client is much lower than what would be expected based on the measured network connection speed between the two VMs and the measured speed of reading the file directly on the server. The VMs are running Ubuntu 9.04 and the server is using the nfs-kernel-server package. According to various NFS tuning resources, changing the number of nfsd threads (in my case kernel threads) can affect performance. Usually this advice is framed in terms of increasing the number from the default of 8 on heavily-used servers. What I find in my current configuration: RPCNFSDCOUNT=8: (default): 13.5-30 seconds to cat a 1GB file on the client so 35-80MB/sec RPCNFSDCOUNT=16: 18s to cat the file 60MB/s RPCNFSDCOUNT=1: 8-9 seconds to cat the file (!!?!) 125MB/s RPCNFSDCOUNT=2: 87s to cat the file 12MB/s I should mention that the file I'm exporting is on a RevoDrive SSD mounted on the server using Xen's PCI-passthrough; on the server I can cat the file in under seconds ( 250MB/s). I am dropping caches on the client before each test. I don't really want to leave the server configured with just one thread as I'm guessing that won't work so well when there are multiple clients, but I might be misunderstanding how that works. I have repeated the tests a few times (changing the server config in between) and the results are fairly consistent. So my question is: why is the best performance with 1 thread? A few other things I have tried changing, to little or no effect: increasing the values of /proc/sys/net/ipv4/ipfrag_low_thresh and /proc/sys/net/ipv4/ipfrag_high_thresh to 512K, 1M from the default 192K,256K increasing the value of /proc/sys/net/core/rmem_default and /proc/sys/net/core/rmem_max to 1M from the default of 128K mounting with client options rsize=32768, wsize=32768 From the output of sar -d I understand that the actual read sizes going to the underlying device are rather small (<100 bytes) but this doesn't cause a problem when reading the file locally on the client. The RevoDrive actually exposes two "SATA" devices /dev/sda and /dev/sdb, then dmraid picks up a fakeRAID-0 striped across them which I have mounted to /mnt/ssd and then bind-mounted to /export/ssd. I've done local tests on my file using both locations and see the good performance mentioned above. If answers/comments ask for more details I will add them.

• Apache on Ubuntu very slow on inital calls, very fast afterwards

  - by papakost

  I own an Ubuntu 10 VPS Server with Apache 2 hosting a Magento website. The first hit to the site from any client takes about 15-20 sec, while the subsequent hits from the same client take 0-1 sec. I suppose it doesn't have to do with Magento caching, because this happens also when the first call is on a very light page and the next calls are on heavy ones. Does anyone have an idea on what is going wrong here?

• How do I configure a swap partition using swapspace

  - by jcalfee314

  I finally have the swapspace project installed and running (via init.d). The purpose is to have a dynamically re-sizing swap partition. I'm clueless however on how to use it. It has good documentation but just does not go into that last step. How to I configure a swap partition using swapspace? The process is probably the same for any 3rd party program that would provide a swap space implementation to the kernel. I know this was intended to run as a process because the project provides an init.d script.

• Is there a version of Debian-Lenny that is legal for export from the US?

  - by molecules

  I wanted to bundle my application in a Debian-Lenny Virtual Machine so others could download it and run it without having to configure anything. However, I don't want to have to worry about US legal issues. Many of the packages in a default Debian installation include encryption algorithms. Are all default versions export-safe?    If not, is there an export-safe version?       If not, is there an easy way to make one?

• Title: Better logging for cronjob output

  - by Stefan Lasiewski

  I am looking for a better way to log cronjobs. Most cronjobs tend to spam email or the console, get ignored, or create yet another logfile. In this case, I have a Nagios NSCA script which sends data to a central Nagios sever. This send_nsca script also prints a single status line to STDOUT, indicating success or failure. 0 * * * * root /usr/local/nagios/sbin/nsca_check_disk This emails the following message to root@localhost, which is then forwarded to my team of sysadmins. Spam. forwarded nsca_check_disk: 1 data packet(s) sent to host successfully. I'm looking for a log method which: Doesn't spam the messages to email or the console Don't create yet another krufty logfile which requires cleanup months or years later. Capture the log information somewhere, so it can be viewed later if desired. Works on most unixes Fits into an existing log infrastructure. Uses common syslog conventions like 'facility' Some of these are third party scripts, and don't always do logging internally.

• File descriptor linked to socket or pipe in proc

  - by primero

  i have a question regarding the file descriptors and their linkage in the proc file system. I've observed that if i list the file descriptors of a certain process from proc ls -la /proc/1234/fd i get the following output: lr-x------ 1 root root 64 Sep 13 07:12 0 -> /dev/null l-wx------ 1 root root 64 Sep 13 07:12 1 -> /dev/null l-wx------ 1 root root 64 Sep 13 07:12 2 -> /dev/null lr-x------ 1 root root 64 Sep 13 07:12 3 -> pipe:[2744159739] l-wx------ 1 root root 64 Sep 13 07:12 4 -> pipe:[2744159739] lrwx------ 1 root root 64 Sep 13 07:12 5 -> socket:[2744160313] lrwx------ 1 root root 64 Sep 13 07:12 6 -> /var/lib/log/some.log I get the meaning of a file descriptor and i understand from my example the file descriptors 0 1 2 and 6, they are tied to physical resources on my computer, and also i guess 5 is connected to some resource on the network(because of the socket), but what i don't understand is the meaning of the numbers in the brackets. Do the point to some property of the resource? Also why are some of the links broken? And lastly as long as I asked a question already :) what is pipe?

• Hadoop Rolling Small files

  - by Arenstar

  I am running Hadoop on a project and need a suggestion. Generally by default Hadoop has a "block size" of around 64mb.. There is also a suggestion to not use many/small files.. I am currently having very very very small files being put into HDFS due to the application design of flume.. The problem is, that Hadoop <= 0.20 cannot append to files, whereby i have too many files for my map-reduce to function efficiently.. There must be a correct way to simply roll/merge roughly 100 files into one.. Therefore Hadoop is effectively reading 1 large file instead of 10 Any Suggestions??

• How to configure OpenVPN server to use custom default gateway?

  - by Arenim

  I have a vpn server at address 10.1.0.2 and the server have another ip in it's network -- 10.0.0.2 in his subnet (it's a tun2socks router). But default server's gateway is NOT 10.0.0.2 (and it's ok) but another external IP. I want all the client's traffic to be forwarded through this ip address -- 10.0.0.2. Here is part of my server's config: dev tap0 server-bridge 10.1.0.1 255.255.255.0 10.1.0.50 10.1.0.100 push "route 10.0.0.0 255.255.255.0" ; now client can ping 10.0.0.2 push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 10.1.0.1" push "dhcp-option WINS 10.1.0.1" in fact i want some like push "redirect-gateway 10.0.0.2" How can I achieve this?

• saving data from a failing drive

  - by intuited

  An external 3½" HDD seems to be in danger of failing — it's making ticking sounds when idle. I've acquired a replacement drive, and want to know the best strategy to get the data off of the dubious drive with the best chance of saving as much as possible. There are some directories that are more important than others. However, I'm guessing that picking and choosing directories is going to reduce my chances of saving the whole thing. I would also have to mount it, dump a file listing, and then unmount it in order to be able to effectively prioritize directories. Adding in the fact that it's time-consuming to do this, I'm leaning away from this approach. I've considered just using dd, but I'm not sure how it would handle read errors or other problems that might prevent only certain parts of the data from being rescued, or which could be overcome with some retries, but not so many that they endanger other parts of the drive from being saved. I guess ideally it would do a single pass to get as much as possible and then go back to retry anything that was missed due to errors. Is it possible that copying more slowly — e.g. pausing every x MB/GB — would be better than just running the operation full tilt, for example to avoid any overheating issues? For the "where is your backup" crowd: this actually is my backup drive, but it also contains some non-critical and bulky stuff, like music, that aren't backups, i.e. aren't backed up. The drive has not exhibited any clear signs of failure other than this somewhat ominous sound. I did have to fsck a few errors recently — orphaned inodes, incorrect free blocks/inodes counts, inode bitmap differences, zero dtime on deleted inodes; about 20 errors in all. The filesystem of the partition is ext3.

• Cannot Login as root

  - by Josh Moore

  At my work we ship our product on pre-installed servers as a software/hardware package. We are using open SUSE 10.3 for the OS and we setup and we always log in with the root user to do maintenance on the box. Recently we just had box returned to us that the customer said the could not longer connect to the box through the network interface. So when I started to work on the box I run into the this problem: At the command prompt to login i type the user name "root" and hit enter. Then even before it asks me for a password I get "Login incorrect". I have never seen this behavior before and could not find any information about it online. Does anybody know what is going on? Thanks.

• Script to run chown on all folders and setting the owner as the folder name minus the trailing /

  - by Shikoki

  Some numpty ran chown -R username. in the /home folder on our webserver thinking he was in the desired folder. Needless to say the server is throwing a lot of wobbelys. We have over 200 websites and I don't want to chown them all individually so I'm trying to make a script that will change the owner of all the folders to the folder name, without the trailing /. This is all I have so far, once I can remove the / it will be fine, but I'd also like to check if the file contains a . in it, and if it doesn't then run the command, otherwise go to the next one. #!/bin/bash for f in * do test=$f; #manipluate the test variable chown -R $test $f done Any help would be great! Thanks in advance!

• rsnapshot stats

  - by Obscur Moirage

  I'd like to retrieve the following stats from rsnapshot files synced added files modded files deleted files Is there a feature to retrieve these in rsnapshot, or is there another product that's able to do it? EDIT: As requested, I'll try to show that I'm not just asking what I want to do without any research. I wasn't able to locate any rsnapshot feature doing this. Maybe I'm searching in a wrong direction. So, I've built a not very pretty script, called each time before rsnapshot is ran. This Perl script stores each file MD5, in order to compare backup files structures between rsnapshot updates. I'm pretty sure it's worthless to show this code here. I think that keeping an eye on what change on a server, for example, is a useful feature. So, I'm asking. @pauska Most of the time, I'm trying to search for an answer myself, which is not the case here. Thanks
