  • Help with user login on Centos 5.6

    - by Owen
    I added a user for the sole purpose of using SU for root. I did not allow the creation of a home directory when creating the user. So now when I login as this user I get the following: Could not chdir to home directory /home/MYUSERNAME: No such file or directory Couldn't resolve homedir for current user at - line 0 BEGIN failed--compilation aborted. Couldn't resolve homedir for current user at - line 0 BEGIN failed--compilation aborted. Is this an error, and if so how do I fix it so it is not looking to "resolve" the homedir?

  • Formatting LVM partition with HFS+

    - by Pyetras
    I've already tried fsck.hfsplus from hfsprogs, which doesn't do anything at all, and gparted (doesn't work with LVM). Are there any other ways to do that? If all else fails I have OSX install DVD, but I'm not sure if its installer would see a LVM partition (and running it just to check that would be quite troublesome, as I don't have a DVD drive ATM).

  • Keeping folder of files in sync over 3 machines

    - by Wizzard
    Morning, Got 3 machines that have user content on them, which I need to keep in sync. This is a 3 way sync. Currently I run rsync but we just don't handle deletes. Have looked at something like gluster, but that seems a little over the top Any other software out there to do a 3 way sync, or a good network file system...? There is for web servers so we don't want a slow / IO hungry process. 3 servers... user content could be added to 1 and needs to be moved to other two.

  • udev rule not being executed

    - by jyavenard
    I have the following device that udevadm lists as: looking at device '/devices/pci0000:00/0000:00:1c.7/0000:09:00.0/usb6/6-2/6-2:1.0/ttyUSB0/tty/ttyUSB0': KERNEL=="ttyUSB0" SUBSYSTEM=="tty" DRIVER=="" looking at parent device '/devices/pci0000:00/0000:00:1c.7/0000:09:00.0/usb6/6-2/6-2:1.0/ttyUSB0': KERNELS=="ttyUSB0" SUBSYSTEMS=="usb-serial" DRIVERS=="pl2303" ATTRS{port_number}=="0" looking at parent device '/devices/pci0000:00/0000:00:1c.7/0000:09:00.0/usb6/6-2/6-2:1.0': KERNELS=="6-2:1.0" SUBSYSTEMS=="usb" DRIVERS=="pl2303" ATTRS{bInterfaceNumber}=="00" ATTRS{bAlternateSetting}==" 0" ATTRS{bNumEndpoints}=="03" ATTRS{bInterfaceClass}=="ff" ATTRS{bInterfaceSubClass}=="00" ATTRS{bInterfaceProtocol}=="00" ATTRS{supports_autosuspend}=="1" So I created the rule: KERNEL=="ttyUSB0", SUBSYSTEM=="tty", SUBSYSTEMS=="usb-serial", DRIVERS=="pl2303", KERNELS=="6-2:1.0", SYMLINK+="cc128serial" this doesn't work. However if I do: KERNEL=="ttyUSB0", SUBSYSTEM=="tty", SUBSYSTEMS=="usb-serial", DRIVERS=="pl2303", SYMLINK+="cc128serial" then it works. I tried with KERNELS=="6*" etc.. to no available any ideas ? thanks

  • Why is /dev/urandom only readable by root since Ubuntu 12.04 and how can I "fix" it?

    - by Joe Hopfgartner
    I used to work with Ubuntu 10.04 templates on a lot of servers. Since changing to 12.04 I have problems that I've now isolated. The /dev/urandom device is only accessible to root. This caused SSL engines, at least in PHP, for example file_get_contents(https://... to fail. It also broke redmine. After a chmod 644 it works fine, but that doesnt stay upon reboot. So my question. why is this? I see no security risk because... i mean.. wanna steal some random data? How can I "fix" it? The servers are isolated and used by only one application, thats why I use openvz. I think about something like a runlevel script or so... but how do I do it efficiently? Maby with dpkg or apt? The same goes vor /dev/shm. in this case i totally understand why its not accessible, but I assume I can "fix" it the same way to fix /dev/urandom

  • Apache downloads php files instead of running their source

    - by Devils Child
    I have just recently upgraded PHP 5.3 to 5.4 on my Debian Squeeze server. Now, instead of executing PHP files, Apache just downloads them, which is really bad. When I try to follow these steps, I get "broken packages" upon installing the libapache2-mod-php5 package. Also the answer tells me to add something to my httpd.conf, but it's empty. Question: How can I make apache execute php files again, instead of just passing them through as download? dpkg -l | grep php returns this rc libapache2-mod-php5 5.3.3-7+squeeze15 server-side, HTML-embedded scripting language (Apache 2 module) rc php5-cli 5.3.3-7+squeeze15 command-line interpreter for the php5 scripting language ii php5-common 5.4.15-1~dotdeb.2 Common files for packages built from the php5 source rc php5-gd 5.3.3-7+squeeze15 GD module for php5 rc php5-mcrypt 5.3.3-7+squeeze15 MCrypt module for php5 rc php5-mysql 5.3.3-7+squeeze15 MySQL module for php5 rc php5-suhosin 0.9.32.1-1 advanced protection module for php5 rc phpmyadmin 4:3.3.7-7 MySQL web administration tool And apt-get install libapache2-mod-php5 produces this error The following packages have unmet dependencies: libapache2-mod-php5 : Depends: libdb5.1 but it is not installable Depends: libssl1.0.0 (>= 1.0.0) but it is not installable Depends: libxml2 (>= 2.8.0) but 2.7.8.dfsg-2+squeeze7 is to be installed Recommends: php5-cli but it is not going to be installed E: Broken packages

  • Started an application through SSH, command line now gone, what happens next?

    - by Chris Dutrow
    Context: This is a very basic question Using Putty and SSH for the first time to do some serious server setup and run into the situation where I have started a process that I do not want to stop. The process is the gunicorn WSGI HTTP Server (running on Centos 6.3). The command I used to start the process is (as per their Quick Start): gunicorn -w 4 myapp:app At this point in the work session, I have lost the command prompt. This must be such a non-issue that it doesn't even enter into an experienced user's consciousness. But unfortunately at my level of experience, I am left with several fundamental questions: Does the fact that I have lost the command prompt mean that the process is still running? How do I get back to the command prompt without killing the process? How do I come back and monitor the process later? How do I eventually kill the process? Any help is appreciated, thanks so much!

  • running commands as other users - best method

    - by linuxrawkstar
    When running commands as other users from the command line, what is recommended best practice? In the past I've used sudo like so: sudo -u username command [args] I've been told (with no specific reasons why) that using sudo for this purpose is wrong. I'd like to know why. Is there some "best way" to accomplish this? For example, I've also used the su command like so: su username - -c "command [args]" I can't imagine why either of these methods would be "bad". Your thoughts?

  • nfs mount fails in Ubuntu 10, but not with -v

    - by stuartreynolds
    (1) mount -t nfs remotehost:/remotedir localmountpoint -o owner,rw (2) mount -v -t nfs remotehost:/remotedir localmountpoint -o owner,rw (1) Used to work with Ubuntu 9 and now fails with Ubuntu 10 (2.6.32-21-generic kernel) with the error: mount.nfs: an incorrect mount option was specified Strangely, adding -v (verbose) in (2) makes the problem go away. This is currently a blocker for me because the fstab line: remotehost:/remotedir localmountpoint nfs owner,rw 0 0 causes the same error (I don't believe I can specify verbose in fstab). Is this a bug in mount or my options really incorrect?

  • Is there a BSD equivalent to "!!"?

    - by CT
    I often find myself issuing a command that I do not have the proper elevated privileges for. On Ubuntu I could use sudo !! This would issue the same command with sudo privlidges. Is there an equivalent on OpenBSD? Edit: I should have been more specific on what version of OpenBSD. I am using OpenBSD 4.8 where sudo seems to be installed by default. I have already created a user besides root and edited my sudoers file to allow for that user to use sudo. My question is, is there already a built-in shortcut for the "!!" to use previous command.

  • Spambot Infection Detection

    - by crankshaft
    My server has been blocked by CBL for participating in curtwail spambot. Initially we suspected that it was coming from a PC and not from the server, but the router is blocking all packets on 25 except those coming from the server. I have just executed the tcpdump command and every 5 minutes I see a flurry of activity on port 25 that is very suspicious and I am sure that there is some process running on the server: 13:02:30.027436 IP exprod5og110.obsmtp.com.53803 > ubuntu.local.smtp: Flags [S], seq 171708781, win 5744, options [mss 1436,sackOK,TS val 3046699707 ecr 0,nop,wscale 2], length 0 I have stopped postfix, and yet there is still traffic on port 25 above. But how can I find what process is actually communicating on port 25 as it only rund for a few seconds and so for example lsof -i :25 will never catch it. I have been working on this now for 2 days, it is a live server and I cannot simply shut it down, any suggestion on how I can detect the source of this email bot process ?

  • Cross-platform centralized desktop password manager

    - by Dave
    I have been using KeePass as a desktop password manager on Windows for many years. Love it! However, I am now needing to work on different platforms much of my day (Windows 7, Windows XP, Mac OS X, Ubuntu, and OpenSUSE.) I'm looking for a password manager I can share across all these platforms. My ideal solution would: Run natively (not in a virtual machine) on all platforms. Store the "official" copy of the password data on a local network so I can get to it from any and all machines. It is OK if it locks (or becomes read-only) when one client is accessing it. Keep a local cached copy (read-only is fine) so I can still get to my passwords when disconnected from the network. Does any such beast exist?

  • SSH login without password prompt

    - by user477519
    I am trying to set up Opennebula. I want to set up my local host so that I can log into my remote host without having to use the password. I have followed the instructions in the "Secure Shell Access" section in the installation instructions. I can not log into my remote host from my local host, but I can log into my local host from my remote host. Not sure what's going on. Any help would be appreciated. Thanks

  • Disaster - partitions lost, data seemingly alive, how to recover?

    - by a2h
    I've used TestDisk and it's written my old partition structure of a ~20GiB partition for Vista, ~25GiB partition for 7 (but it now shows up as unallocated) and a ~400GiB partition for documents. What it's meant to be is a 30GiB partition for 7, some unallocated space, and a ~400GiB partition for documents. So currently, I have access to all my documents, but not any of the programs I've installed on C:, or AppData, because my boot partition is now supposedly a 20GB vista partition. I've tried using my Windows 7 install disc's repair function, but that did nothing beyond wasting about 10 minutes of my time. I'm currently posting from an Ubuntu live CD. Any help?

  • How to get the CentOS 5.6 alsa drivers which will really work with one shot, without any internet.

    - by 89899.3K
    I have one chance to install this in my server on site. Server that i am running is CentOS 5.6 (Dell R310, RAID1) where i need to install alsa-sound driver so that anything related to audio recording from rtsp is working (rail station/rail passing video recording including audio, where audio is not working). Unfortunately i do not have any kind of internet in that odd none human location so yum will not work for me. I need a offline way to install alsa drivers including missing dependencies if arise. What and where i can download this to my usb or cd? so that i can successfully install it (like mission complete). Thanks

  • Touchscreen on KDE and Ubuntu?

    - by The Quantum Physicist
    I just bought a Lenovo Yoga 2 Pro... I liked the activity of the touchscreen on Windows, and it makes sense as it does on my smart phone. However, I'm not a regular windows user, so I installed Kubuntu 14.04, and everything looks fine, except that the activity of the touchscreen is so silly that it's useless. Why? Because all the touchscreen does is a single mouse with left click. For example, if I touch the screen for a relatively long time, I don't get the effect of a right click. How do I configure the touchscreen properly to get the activity expected on Ubuntu and KDE? Thanks for any efforts.

  • sudoers entries

    - by Pochi
    Is there a way to have a sudoers entry that allows executing of only a particular command, without any extra arguments? I can't seem to find a resource that describes how command matching works with sudoers. Say I want to grant sudo for /path/to/executable arg. Does an entry like the following: user ALL=(ALL) /path/to/executable arg strictly allow sudo access to a command exactly matching that? That is, it doesn't grant user sudo privileges for /path/to/executable arg arg2?

  • I do not understand -printf script

    - by jerzdevs
    I have taken over the responsibility of RHLE5 scripting and I've not had any training in this platform or BASH scripting. There's a script that has multiple pieces to it and I will ask only about the second piece but also show you the first, I think it will help with my question below. The first part of the script shows the output of users on a particular server: cut -d : -f 1 /etc/passwd The output will look something like: root bin joe rob other... The second script requires me to fill in each of the accounts listed from the above script and run. From what I can gather, and from my search on the man pages and other web searches, it goes out and finds the group owner of a file or directory and obviously sorts and picks out just unique records but not really sure - so that's my question, what does the below script really do? (The funny thing is, is that if I plug in each name from the output above, I'll sometimes receive a "cannot find username blah, blah, blah" message.) find username -printf %G | sort | uniq

  • How do I reduce RAM usage on my server?

    - by Abs
    I have recently launched a site that is very popular but I am having trouble with scalability. My site makes heavy use of FFmpeg and at peak times RAM usage hits the 2 GB point quickly and the swap file starts getting used. CPU usage starts rising too. Users complain that the site is slow. They say this because all FFmpeg instances run very slow because of the number running at the same time. Users make use of FFmpeg on my server in real time. Is there anything I can consider or do to ease down the usage of the server and RAM just shooting up? Maybe there is something better than FFmpeg (!). Is the only solution "throwing some cash" at a more powerful server? I have given little information, please ask for more, so this problem can be solved.
