• FreeNAS - how to "Exclude from file" in Rsyncd (GUI)

  - by user179181

  I am trying to set rsync tasks to Pull user profiles from 11 Windows machines running DeltaCopy Server and then configure ZFS periodic snapshot tasks for a backup solution. So far this has been working fine, although i would like to exclude certain file types like .DAT or NTUSER.DAT. My Exclusion file resides on the local ZFS Dataset (Receiving side) and is as follows: Temp Temporary Internet Files NTUSER.DAT NTUSER.DAT.LOG *.dat *.tmp *.DAT.log *.ost *.pst The command i typed under Auxiliary Parameters (Rsyncd Global Conf under services)is as follows: exclude from = /mnt/Storage/User_Profiles/exclude.txt Ive tried deleting the .DAT files from the receiving end and just as i start to get excited i click refresh and there they are again

• IPtables rate-limit, What are the differences between modules? Recent, Limit

  - by TechZilla

  I am doing some rate-limiting with IPtables, and i'm not sure if I should use "Recent" or "Limit" What are the differences between the two? If they both achieve the same result, which one has better performance? I would like to know, regardless if any difference would be perceivable. I am looking to ACCEPT if under limit, and REJECT if over. I'm not interested in thus bandwidth throttling, I don't want a queue. I don't need any syntax examples, both have ample use examples online. I have also used Limit in the past. I appreciate any responses.

• sshd: How to enable PAM authentication for specific users under

  - by Brad

  I am using sshd, and allow logins with public key authentication. I want to allow select users to log in with a PAM two-factor authentication module. Is there any way I can allow PAM two-factor authentication for a specifc user? I don't want users - By the same token - I only want to enable password authentication for specific accounts. I want my SSH daemon to reject the password authentication attempts to thwart would-be hackers into thinking that I will not accept password authentication - except for the case in which someone knows my heavily guarded secret account, which is password enabled. I want to do this for cases in which my SSH clients will not let me do either secret key, or two-factor authentication.

• .desktop shortcuts aren't working for java applications in LXDE

  - by chaz

  I just installed minecraft on my LXDE desktop/Lubuntu machine and I'm trying to create a .desktop file on the desktop that executes java -jar ~/minecraftlauncher.jar. The command works in bash scripts and the terminal but refuses to work when I click on my .DESKTOP shortcut which is suppose to execute the same command. I've experimented with other jars and they can't seem to start too. Here is my xsession log: ** (pcmanfm:1572): DEBUG: launch command: <java -jar ~/Downloads/minecraft_server.jar> ** (pcmanfm:1572): DEBUG: sn_id = pcmanfm-1572-administrator-Dimension-3000-java-14_TIME14031891 Unable to access jarfile ~/Downloads/minecraft_server.jar ** (pcmanfm:1572): DEBUG: launch command: <java -jar ~/minecraftlauncher.jar> ** (pcmanfm:1572): DEBUG: sn_id = pcmanfm-1572-administrator-Dimension-3000-java-15_TIME14070158 Unable to access jarfile ~/minecraftlauncher.jar UPDATE: Whoops, it seems to work when I give an absolute path. I guess the home path is something else. UPDATE: I guess X doesn't resolve the home specifier. I ran a .desktop file that executed a script that outputs the current directory, and it seems to be correct.

• NFS mount mounted inside another NFS mount disappears randomly

  - by espenfjo

  I have quite an odd issue where my nested NFS mounts just disappear randomly from time to time. The fstab entries look somewhat like this: nfs:/home /home/nfs rw,hard,intr,rsize=32768,noatime,nocto,proto=tcp 0 0 nfs:/bigdir /home/bigdir nfs rw,hard,intr,rsize=32768,noatime,nocto,proto=tcp,bg 0 0 The issue is that from time to time the "/home/bigdir" folder will be empty, even though mtab think that the share is still mounted. nfsstat et. al. do also think the share is still mounted. Only thing that works is by unmounting, and then (re)mounting the bigdir share. The server side is a NetApp. The client side is RHEL5.5, 2.6.18-194 kernel (Yes, I know 5.8 is out, but as far as I can see there are no erratas for this particular issue). I can use various hacks like automount, or mounting it to another path and then using --mount bind, but I would like to fix the underlying issue. -- Best regards Espen Fjellvær Olsen

• Installing checkinstall on x86_64 bit

  I downloaded the source for check install. checkinstall-1.6.2.tar.gz. I then tar -xzvf checkinstall-1.6.2.tar.gz Then I make.

But there is no any memory problems reported in munin monitoring: As you see system uses around 0.2G and 1G is available. So my question is: Is it xen specific problem, that real memory usage and memory usage that shows munin are different (I've never seen such problems oh real hardware machines)? Or maybe it is just monitoring problem, that can't catch moment when there is unusual high load and domU go down? And how I can to defeat this problem? it is really annoying to catch messages in e-mail that domU went down. Btw, such situation was when domU had 2G memory.

• iptables to block VPN-traffic if not through tun0

  - by dacrow

  I have a dedicated Webserver running Debian 6 and some Apache, Tomcat, Asterisk and Mail-stuff. Now we needed to add VPN support for a special program. We installed OpenVPN and registered with a VPN provider. The connection works well and we have a virtual tun0 interface for tunneling. To archive the goal for only tunneling a single program through VPN, we start the program with sudo -u username -g groupname command and added a iptables rule to mark all traffic coming from groupname iptables -t mangle -A OUTPUT -m owner --gid-owner groupname -j MARK --set-mark 42 Afterwards we tell iptables to to some SNAT and tell ip route to use special routing table for marked traffic packets. Problem: if the VPN failes, there is a chance that the special to-be-tunneled program communicates over the normal eth0 interface. Desired solution: All marked traffic should not be allowed to go directly through eth0, it has to go through tun0 first. I tried the following commands which didn't work: iptables -A OUTPUT -m owner --gid-owner groupname ! -o tun0 -j REJECT iptables -A OUTPUT -m owner --gid-owner groupname -o eth0 -j REJECT It might be the problem, that the above iptable-rules didn't work due to the fact, that the packets are first marked, then put into tun0 and then transmitted by eth0 while they are still marked.. I don't know how to de-mark them after in tun0 or to tell iptables, that all marked packet may pass eth0, if they where in tun0 before or if they going to the gateway of my VPN provider. Does someone has any idea to a solution? Some config infos: iptables -nL -v --line-numbers -t mangle Chain OUTPUT (policy ACCEPT 11M packets, 9798M bytes) num pkts bytes target prot opt in out source destination 1 591K 50M MARK all -- * * 0.0.0.0/0 0.0.0.0/0 owner GID match 1005 MARK set 0x2a 2 82812 6938K CONNMARK all -- * * 0.0.0.0/0 0.0.0.0/0 owner GID match 1005 CONNMARK save iptables -nL -v --line-numbers -t nat Chain POSTROUTING (policy ACCEPT 393 packets, 23908 bytes) num pkts bytes target prot opt in out source destination 1 15 1052 SNAT all -- * tun0 0.0.0.0/0 0.0.0.0/0 mark match 0x2a to:VPN_IP ip rule add from all fwmark 42 lookup 42 ip route show table 42 default via VPN_IP dev tun0

• Command to find the source package of a binary?

  - by Delan Azabani

  I know there's a which command, that echoes the full name of a binary (e.g. which sh). However, I'm fairly sure there's a command that echoes the package that provides a particular binary. Is there such a command? If so, what is it? I'd like to be able to run this: commandName ls and get coreutils for example.

• How can I unbind a UDP port that has no entry in lsof?

  - by Chocohound

  On my Mac, I have a UDP port that is "already in use", but doesn't have an associated process: sudo netstat -na | grep "udp.*\.500\>" shows udp4 0 0 192.168.50.181.500 *.* udp4 0 0 192.168.29.166.500 *.* sudo lsof doesn't show a process on port 500 (ie sudo lsof -i:500 -P reports nothing). Note I'm using 'sudo' on both commands so it should show all processes. (rebooting works, but looking for something less disruptive) How can I unbind port 500 so I can use it again?

• Not able to delete file from server with permissions of 644 via PHP script

  - by letseatfood

  I am trying to delete JPEG files that were uploaded to the server via FTP. The files are uploaded and written with permissions of 644. The owner and group of the upload directory are mike and mike. I have tried changing the owner and group to www-data, but that does not seem to work. I am trying to delete the files with a PHP script using unlink(). This works on the production server (which is a hosting service), but not my development server, which is a LAMP setup. This leads me to believe it has something to do with permissions on my development server.

• HALEVT troubleshooting: VFAT usb storage device gets mounted with root:root user:group

  - by Nova deViator

  Hi, i'm banging my head for number of days around this problem. using Halevt for automounting, everything mostly works, but the only thing is that Halevt mounts external USB storage devices as root. So, as user i cannot write to files on them. Halevt gets run as halevt user on boot through /etc/init.d script. This is Ubuntu Lucid with Awesome WM. No GDM. Running halevt as user seem to not work (halevt runs but doesn't respond on Insert) I know HAL is deprecated and removed and i should probably write my own UDEV rules, but until then it seems there must a be simple hack that enables mounting VFAT/NTFS devices with specific uid/gid. this question/answer helps a lot, but not specifically to the above.

• Amazon EC2 tools for Debian?

  - by Jonik

  What is the recommended way of getting command-line Amazon EC2 tools on Debian? So, basically the same as this question, but for EC2 instead of S3. Ubuntu has ec2-ami-tools and ec2-api-tools, but I couldn't find equivalent packages for Debian. A blog post titled "Install EC2 AMI & API tools in Debian" talks about installing Amazon's packages outside package management, but that seems a little clumsy.

• Should I split my website into different servers

  - by Nyxynyx

  I have a website where a user uploads photos, the photos gets resized and thumbnailed, and stored on the server. At the same time, there are some INSERTS into a MySQL table regarding the photo uploaded (like description, user id etc). The site currently runs off a managed VPS, and I love the support it provides. However it is expensive to store the many small photos and the resizing and thumbnailing processes do cause spikes on the app performance. (Amazon S3 is pretty expensive, especially considering the costs for uploading many small files) Question: Will it be a good idea to move the image processing operations and image storage to another server which is an unmanaged dedicated server with a much lower cost/gb and keep the current VPS for its 24/7 support and hosting the webapp? Or should I move the entire site to the dedicated server?

• How to Find Out What Version of Display Driver is Installed

  - by Artium

  One of my favorite games, "Wolfenstein Enemy Territory", has stopped working lately. It throws a segfault during the initialization phase. I suspect that the reason is a recent update to the video card driver. The problem started after I updated Ubuntu but I do not remember if there was a driver update in the list. My question is how can I check this. How can I view the current version of the display driver installed and the date it was last updated? If I discover that this is indeed the problem, will it be possible to revert the update and stay with the previous version of the driver?

• How to change a physical partition system to LVM?

  - by Daniel Hernández

  I have a server with Debian that have 3 physical partitions covering all the disk: boot, root y swap. Now I want to replace that partitions with LVM partitions. I know how install Debian with LVM at beginning, but in this case I can't install the system at beginning because the provider gets me a server with remote access and the system installed in this way. How can I change that partitions using only an ssh connection and possibly other remote server where to put some temporal data?

• How to add a broadcast address to loopback with ifconfig on a OS/X?

  - by chrisapotek

  I am trying to use ifconfig to turn on broadcast on my loopback interface. It currently reads: lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 As you can see, no broadcast address! :( :( :( I tried this on OS/X but it did not work and it did not give any error or feedback: ifconfig lo0 broadcast 127.255.255.255 Any guru would know that? I have one server that sends one packet. I have two clients running on the same machine as the server. I need them to pick up the packet WITHOUT having to force the server to send it twice.

• infiniband network between 3 servers

  - by grumpf

  Let's say I have 3 different servers, each one with an infiniband card. Each card has 2 different ports. (I don't know about the model yet) Is it possible to create 3 different networks and to allow the 3 servers to communicate with each other without any problems? (and any spof). I guess I just have to setup the /etc/hosts correctly. I really don't know about infiniband, so please help me :) Thanks in advance. EDIT: Point is to NOT USE a switch!

• External monitor image not centered in the screen

  - by kemp

  I'm using Xorg 7.5 on a Radeon HD4870 with the FOSS radeonhd server on my HP 6830s. The laptop has a VGA connector and I attach it to a 37" panasonic plasma TV. It works fine except for a little annoyance: when activated, the TV screen is set to the resolution of 1360x768 (which it reports as being the highest it supports) but all the image is shifted by about 100 pixels to the right. I can't see the leftmost part of the page, and I have a black vertical bar to the right. If I change the resolution to 1024x768 there is no shifting, the image fills the entire screen with no parts hidden, but at this resolution the image is stretched. How can I tune the position on the external monitor so that the image is centered in the screen filling it entirely?

• Where is the xorg.conf file in Karmic Koala (Ubuntu 9.10) ?

  - by jfmessier

  I am trying to change this xorg.conf file that I used to modify under Ubuntu 9.04, so it can have the higher resolutions of my monitor. Under 9.04, the monitor was unknown, and I had to key in all resolutions in the file, and although it is found under 9.10, 9.10 does not have the highest resolution that My monitor can sustain. How can I change such setting ? Is xorg.conf moved, or replaced ? Merci :-) JF
