  • Fix stubborn 'Setting locale failed.'

    - by user60129
    I have a very stubborn, well-known locale error on Ubuntu 9.10: perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LC_TIME = "custom.UTF-8", LANG = "en_US.UTF-8" Tried the following: Added LANG=en_US.UTF-8 and LC_ALL=en_US.UTF-8 to /etc/environment Run apt-get install --reinstall locales (error: perl: warning: Falling back to the standard locale ("C"). /usr/bin/mandb: can't set the locale; make sure $LC_* and $LANG are correct) Run sudo dpkg-reconfigure locales. Result: Cannot set LC_ALL to default locale: No such file or directory, and then updates locales all locales including en_US.UTF-8 sudo locale-gen updates all locales successfully, including en_US.UTF-8 sudo locale-gen un_US en_US.UTF-8 gives no error nor other output In /etc/default/locale it says LANG="en_US.UTF-8" echo $LANG gives en_US.UTF-8 /var/lib/locales/supported.d/local says en_US.UTF-8 UTF-8 locale -a gives me: C en_AG en_AU.utf8 en_BW.utf8 en_CA.utf8 en_DK.utf8 en_GB.utf8 en_HK.utf8 en_IE.utf8 en_IN en_NG en_NZ.utf8 en_PH.utf8 en_SG.utf8 en_US.utf8 en_ZA.utf8 en_ZW.utf8 POSIX So well... I am pretty much out of options I can think of. Anybody any idea?? Thanks!

  • Why is MySQL unable to open hosts.allow/hosts.deny?

    - by HonoredMule
    I have a storage server running Nexenta (OpenSolaris kernel, Ubuntu userspace) with MySQL on top of a ZFS storage array, using innodb_file_per_table and ulimit -n set to 8K. mysqltuner.pl confirms the file limit and claims there are 169 files. The following command: pfiles `fuser -c / 2>/dev/null indicates one mysqld process having 485 file/device descriptors (and they're almost all for files) so I don't know how reliable the tuning script is, but it is still way less than 8K and this list also finds no other process which is close to it's limit. The global total number of descriptors in use is around 1K. So what can cause mysqld to be constantly streaming the following errors? [date] [host] mysqld[pid]: warning: cannot open /etc/hosts.allow: Too many open files [date] [host] mysqld[pid]: warning: cannot open /etc/hosts.deny: Too many open files Everything appears to actually be operating fine, but the issue is constantly flooding the admin console and starts right away on a fresh boot (not only reproducible, but always from mysqld and always the hosts files, whose permissions are the default -rw-r--r-- 1 root root). I could, of course, suppress it from the admin console but I'd rather get to the bottom of it and still allow mysqld warnings/errors to reach the admin console. EDIT: not only is the actual file descriptor well within sane limits, the issue also persists (with immediate appearance) even with the file limit raised to 65535 and always only on hosts.allow/deny.

  • How to track things that SHOULD happen, but might not have

    - by Kamiel Wanrooij
    I am running into a couple of issues with some applications we've deployed and maintain. I have the feeling we have approached this with some anti-patterns up to now, but I would like to see how to make this more flexible and stable. In one situation, we have a server at a client which pushes data to us to parse every night (yes, Windows Task Scheduler). This is highly unstable however, so once every month this doesn't happen because of reasons out of our control. This heavily impacts our business since we run with stale data in that situation. In another scenario we have a lot of background job processes that should be running. We already keep them up using bluepill ( http://www.github.com/arya/bluepill ) but obviously restarts happen, both automatically and manually, and people forget things or systems mess up. What I would like to track is events that should occur or should be available. Like the existence of a process, the execution of a program, or the creation/age of a file, and track it when they don't happen or exist. We develop most things in Ruby on Rails, use NewRelic, Bluepill and Munin, and run on Ubuntu. I've been toying around with counting ps aux | grep processname | wc -l in Munin scripts, or capturing the age of a file and raising alerts over 24-26 hours, stuff like that. Is there better tooling to track things that should happen, and raise alerts if they don't? P.S. I know some things are suboptimal, like manually having to define bluepill for applications and then forgetting to do so. The same goes for the push based approach of the first application, a dedicated daemon that manages that on the client side that we control and can track its connection to us might be a much better solution.

  • Help with routing table

    - by user68752
    I have tried to find the answer to my question but not really found a clean and easy solution. I have a box (Ubuntu headless 10.04.1 server, with one Ethernet port) on LAN behind a router (running m0n0wall), that I have successfully installed a PPTP device (ppp0) on, this is working flawlessly (following this link) The thing is I want this box to route all it's internet traffic through the VPN tunnel (ppp0 device) but also being able to access the local LAN on 192.168.1.* subnet. I've succeeded a bit with this, but my problem right now is that I have port forwards (e.g. SSH) done in the m0n0wall pointing to this specific box which forces me to do "add routes" to all boxes that want to access this machine through this specific port. For instance a machine with ip xyz.xyz.xyz.xyz needs to have a static route setup in the routing table on the box to be able to access the box. This is the result of route -n xxx.xxx.137.2 192.168.1.1 255.255.255.255 UGH 0 0 0 eth0 xxx.xxx.137.2 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 yyy.yyy.0.0 192.168.1.1 255.255.0.0 UG 0 0 0 eth0 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 Where xxx is the IPs provided from VPN server. yyy.yyy.0.0 is a net that i want to have access to the box, without this I can't access the box from outside the LAN (via port-forwards done in router software, m0n0wall) is there away round this ugly solution?

  • Mysql Query - That Is Returning Blatanty Incorrect Result

    - by user866190
    I am building a VPS node that is running Ubuntu 10.10LTS, Apache2, Mysql 5.1 and php5. I could not log in to my website admin through the browser, even though I am using the correct login details. So I logged in from the command line to check the results. When I run this query I get expected results: mysql> select * from users; +----+----------+-----------------------+----------+ | id | username | email | password | +----+----------+-----------------------+----------+ | 1 | myUserName | [email protected] | myPassword | +----+----------+-----------------------+----------+ And the same goes for this query: mysql> select * from users where id = 1; +----+----------+-----------------------+----------+ | id | username | email | password | +----+----------+-----------------------+----------+ | 1 | myUserName | [email protected] | myPassword | +----+----------+-----------------------+----------+ 1 row in set (0.00 sec) But when I run this query I get this 'unexpected response': mysql> select * from users where username = 'myUserName' and password = 'myPassword'; Empty set (0.00 sec) I am not sure why this is happening. Any help would be greatly appreciated. BTW.. I will be encrypting the user details but for now I just want to get it set up. Please help, Thanks

  • How should I configure backup of my server?

    - by ed209
    I have just rented a dedicated server. If it helps this is the config I have: CPU1 Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (Cores 8) RAM 15975 MB Disk /dev/sda doesn't contain a valid partition table (=> /dev/sda doesn't) Disk /dev/sdc doesn't contain a valid partition table (=> /dev/sdc doesn't) Disk /dev/sdb doesn't contain a valid partition table (=> /dev/sdb doesn't) Disk /dev/sda: 120.0 GB (=> 114 GIB) Disk /dev/sdc: 3000.6 GB (=> 2861 GIB) Disk /dev/sdb: 3000.6 GB (=> 2861 GIB) /dev/sda is a 120GB SSD. This is where I have Ubuntu/lamp installed. It's the drive that will run my site. With the account I got two other drives of 3000GB each which I really don't need but they came with the account. I figured I could use these to back up my main 120gb drive. So a couple of things I wondered were: Should I use these for backups? How should I back up. The data I want to back up is a user uploads directory full of images and the database. Everything else is either in a code repo or backed up some other way. For example, it would be nice to know there is a disk image of the 120gb drive somewhere that I can copy over should there be any problems but equally I don't mind doing a fresh install of all the software and copying over just the images and database dump. Thanks for your advice! (also, happy to not use the two other drives and backup elsewhere if it's more sensible)

  • Mixing both local and nonlocal addresses on three switches

    - by klew
    I have four computers that have nonlocal addresses like 150.X.X.X. Now I also get another few computers that should be only accessible through a gateway (it will be computing cluster) and they addresses are 10.0.0.X. I also wanted to include those four older computers to this new cluster, but I want them to be accessible from internet on nonlocal addresses (so I would like to set up them on both 150.X.X.X and 10.0.0.X addresses - I've set up it as interface eth0:0 since I have only one NIC). Those new computers have their switch and old computers also have their own switch. Both of them are connected to another (third) switch. The problem is that those old computers see each other (I can ping them), and also new computers see each other, but I can't ping old computer from new computer and vice versa. However pinging on nonlocal adresses works as expected. I looked into switch configuration and didn't find anything useful. I have no idea what I missed here. Can somebody help? All computers have Ubuntu Server 10.04

  • Logging communication between two VMs

    - by sYnfo
    Hi, I'm trying to set up "malware lab" described in this paper. So far, I've set up Windows guest system, adding one Host-only Network adapter, and setting this (sorry if the names aren't exactely correct, I don't have an english language version): - IP Address - 10.0.0.3 - Subnet mask - 255.255.255.0 - Default gateway - not set - Preferred DNS - 10.0.0.4 - Alternate DNS - not set And a Linux guest system - Ubuntu 9.04 - with two Network adapters - Bridged (eth0) and Host-only (eth1), and setting eth1 IP Address to 10.0.0.4, leaving the eth0 to be set by DHCP. Then, I have configured iptables as described in the paper, ie.: iptables -F -t nat iptables -F -t mangle iptables -t mangle -P PREROUTING ACCEPT iptables -t mangle -P OUTPUT ACCEPT iptables -t nat -P PREROUTING ACCEPT iptables -t nat -P POSTROUTING ACCEPT iptables -t nat -P OUTPUT ACCEPT iptables -t mangle -A PREROUTING -i eth0 -j ACCEPT iptables -t mangle -A PREROUTING -p udp -i eth1 -d 10.0.0.3 --dport 53 -j ACCEPT iptables -t mangle -A PREROUTING -p tcp -i eth1 --dport 80 -j ACCEPT iptables -t mangle -A PREROUTING -p tcp -i eth1 -d 10.0.0.3 --dport 6000:7000 -j ACCEPT iptables -t mangle -A PREROUTING -i eth1 -j ULOG iptables -t mangle -A PREROUTING -i eth1 -j DROP Now, when I try to ping the windows system from within the Linux system, it does not reply, I guess thats perfectly normal, because iptables is blocking ping responce. Same when I try to ping the Linux system from within the Windows. But when I try to access any web page from within the Windows system, I would expect that this action should get logged by iptables. But thing is, I don't see any of that kind of lines in log file (If I am looking in the right place, that is. :) It is at /var/log/messages, isn't it?). So, what do you think might be the problem here? I should note, that this is the first time I'm using linux, so don't expect ANY working knowledge of Linux at all... :) Also, since english is not my mother tongue, feel free to point out any gramatical mistakes... :) Thanks for any advice.

  • How can I extract data from Toshiba Satellite with a dead Windows installation?

    - by msanford
    I've got a Toshiba Satellite (unknown model number but bought early 2010) running Windows Vista which throws a kernel error on boot. We don't have the restore/recovery CD any more to restore the Windows partition. I have managed to boot to a Live CD version of Ubuntu 10.10 and have mounted the internal hard drive (which takes nearly 8 minutes). I suspect that the hard drive is malfunctioning, however, because copy tasks of even 30 megs of data to an attached and mounted USB flash drive takes over an hour, and some files are mysteriously inaccessible (not a permissions issue). When browsing folders, it takes many minutes to populate the folder window even with a single tiny file. During the copy tasks, the hard disk sounds like it tries to sleep several times in rapid succession, then continues accessing, it sounds, at full throughput. I initially tried using scp (from the shell) to copy data but I encountered the same local problems. I don't know the S.M.A.R.T. status of the hard disk, either. Is there a more effective way of going about recovering the data on the internal disk, assuming that I can't use a recovery CD and am too cheap to bring it in (for now, at least)?

  • Symlink path can be followed manually, but `cd` returns Permission denied

    - by Ricket
    I am trying to access the directory /usr/software/test/agnostic. There are several symlinks involved in this path. As you can see by the below transcript, I am unable to cd directly to the path, but I can check each step of the way and cd to the symlinked directories until I reach the destination. Why is this? (and how do I fix it?)

  • 3 Monitor PCI-e Graphics card (without tremendous pain)?

    - by N Rahl
    As we are all painfully aware, the only way to get multiple monitors AND compositing (Compiz) on Linux is to use a single graphics card that can drive both (or in my case all three) screens. I bought a Radeon 5750 specifically because it claims to able to drive 3 monitors. I can plug in 3 monitors (2 DVI, 1 HDMI) and the Catalyst Control Center shows all 3, but only 2 can be enabled at a time. The exact message is: The current settings cannot be applied. Possible issues may include: - Display(s) cannot be enabled. - Setting(s) cannot be applied due to insufficient video memory. So I'm going to assume that either the 5750 doesn't support 3 monitors, OR, more likely, ATI couldn't be bothered to add that support to their Linux drivers. So this is a multipart question: First, can anyone suggest a PCI Express Graphics card that can run 3 screens on linux without tremendous pain? I'm looking for something where you install the driver and all three screens "just work". Does such a card exist? Second, if you have a 5750, have you been able to get it to do 3 monitors? I'm running Ubuntu 10.04 at the moment.

  • Virtual Server HDD shrinks without apparent reason

    - by Christian
    We have a virtual hosted Linux server, and in the last few months every now and then the HDD shrinks from 400GB down to the exact byte count that is in use. All existing data can be downloaded and displayed without a problem, but we can't upload or edit any files because of the "full" hard drive. Here is a screenshot, where "size" should be 400GB: This has happened twice before, and again today. The last times, when I reported the issue to the host, they said "that isn't possible, you must be doing it wrong", but soon after the call, the problem vanished without us doing anything, so I suppose that they have some kind of problem they're not willing to admit. Even after the fact, they acted like nothing was wrong and wrote me a mail in which they explained that I can use "df -h" to view available disk space (well duh, how do you think I noticed this particular issue?). Questions about if and what they had done were ignored. It has happened around the 25th to 28th of the month, so I suspect that they might have a cronjob running every 30 days or so which wreaks havoc with some VM configs. I just want to understand the problem, but the host support hasn't been very helpful in that regard. I have tried Googling the issue, but any combination of search terms I can come up with just gives me tutorials on how to change HDD size in a virtual machine. a) What could be the cause of shrinking HDD size in a Ubuntu 12.04.3 LTS server? Could there be anything in our virtual machine or is it more likely to be an issue with the vm host? b) Can I do anything about it without needing to contact the host's support? c) Is there anyway I can prevent this from happening at all?

  • Network external hard drive reports not enough free space

    - by mzhang
    I'm running an Ubuntu (10.04) Samba server on a local network. The server has a 50GB internal drive with only 24MB free. I've shared a folder /samba from that drive. I also have a 1TB NTFS external hard drive mounted to the system. There is a symbiotic link from the Samba shared folder on the nearly-full internal drive to the plenty-of-free-space external drive (i.e. /samba/external_hd). I wish to copy a 3.25GB folder into the (remote) external hard drive, via a Mac (10.6.8). The Mac reports (correctly) that there's 24MB free on the server, and so will not let me copy the folder on the Mac over to the external drive (dragging the folder into /samba/external_hd), failing with a "server does not have enough free space" error. However, it seems that I can still scp the folder into the external drive, via the symbolic link. Is there a reason as to why this is happening (and are there any ways to prevent it)? Is this even good practice (to mount a drive and link into the directory)?

  • Grub Installation Failed: Fatal Error ... now what I do?

    - by eklavya
    I know there are some threads that touch this but I feel I have done something uniquely stupid. hence the post and plea for help. I am a beginner @ Linux. So I have a PC with a HDD (hard disk drive) and SSD (solid state drive) It was running Linux Mint /dev/sda1 - HDD Partition 1 - 2 TB (mounted this is /home /dev/sda2 - HDD Partition 2 - 1 TB (separate back up drive, i was backing up files to this) /dev/sdb1 - SSD Partition 1 - 100 GB (OS) /dev/sdb2 - SSD Partition 2 - 20 GB (Swap) The operating system was Linux Mint and was installed on the /dev/sdb1 i.e the solid state drive. I had partitioned off the sda into 2 TB and 1TB and presented the 2 TB as the /home to the OS. Anyway last night I decided to make a return to Ubuntu via the path of Elementary OS. Everything went fine with the install until it stated that GRUB installed failed and this was a Fatal error (no kidding I said). No I am stuck. I have definitely done something wrong and don't know what it is... My biggest pain is the files on the /dev/sda2. I want to save these before I try something drastic like wiping off the /dev/sda completely. So I have the following questions... Can I use a liveCD USB to save these files ? I can see the /dev/sda2 but was unable to access the files in the liveCD last not least ... how do I fix the main issue here. Why could the OS not install GRUB 2b... why is my SSD the /dev/sdb ... and not /dev/sda. Does that have something to do with it that my master boot record sits on the HDD /dev/sda and not /dev/sdb

  • Route all traffic of home network through VPN

    I have a typical semi advanced home network scenario: A cable modem - eth A wireless router (netgear n600) eth and wlan A home server (Running ubuntu 12.04 LTS, connected over wlan) A bunch of wireless clients (wlan) Lying around I have anoher cheaper wlan router, and two different USB wlan NIC's that are known to work with Linux. ACTA struck. I want to route ALL of my WAN traffic through a remote server through a VPN. For sake of completition, lets say there is a remote server running debian sqeeze where a VPN server is to be installed. The network is then to behave so that if the VPN is not operative, it is separated from the outside world. I am familiar with general system/network practices, but lack the specific detailed knowledge to accomplish this. Please suggest the right approach, packages and configurations you'd use to reach said solution.

  • Why would my network slow down?

    - by monkthemighty
    The network at my work has about 40 computers on it and a quite a few printers. When there are a lot of people working the network will be slow. I can test the ping between my computer and the router and it will keep rising, sometimes to the point that it times out. The router we are using is running Ubuntu on a atom processor and it has 4gb of ram. When the network slows the process Ksoftirq will be using most if not all of the processing power. I have found that Ksoftirq is a process that handles irq requests. Also when the network slows down I have captured packets from the router and using tshark and looked at it using wireshark on my laptop. With the capture show a lot of packets with TCP Dup ACK and TCP Retransmissions. The destinations of the TCP Dup and TCP retransmissions are to most of the computers on the network but there are some that are far more than others. What could this problem be caused by?

  • Can I use Upstart to start a script which requires the user's X session?

    - by ledneb
    I wrote a script which greps through the output of synclient to determine whether a laptop's touchpad has miraculously turned itself off (Ubuntu seems to /love/ doing this recently) and, if so, turns it back on. The script is something like this: #!/bin/bash while true ; do if [ `synclient | grep -e"TouchpadOff[\s]*1" | wc -l` -ge 1 ] ; then synclient TouchpadOff=0 fi sleep(3) done (I don't have the laptop to hand right now but you get the point! I will update later when I'm at my laptop if that's incorrect) So I tried running this as an upstart script so my touchpad can heal itself without any interaction. But it seems synclient doesn't find the current user's X session when my script is upstart'ed. I tried running it by using something like su -c myscript.sh ledneb in my script stanza, but to no avail. Should I be looking in the direction of /etc/X11/xinit/xinitrc rather than upstart? Is there a proper way to have this script run in the context of the current (or even a hard-coded) user's x session?

  • very slow connection to ssh server from client (but not other servers)

    - by AntonOfTheWoods
    I have an Ubuntu 12.04 laptop that is taking so long to connect to various servers (in different data centres) that it seems like a bit of a lottery whether I'll actually get a connection. If I connect to the servers between themselves it's instantaneous, and I've set UseDNS no AddressFamily inet On the servers I'm connecting to (and rebooted for good measure). I also put in the reverse DNS+IP of the cable connection I'm connecting from. If I connect from the laptop via telnet: telnet my.server 22 Then the connection is also instantaneous, so it doesn't appear to be a problem with an intervening firewall. I have the same behaviour whether I connect with the IP, a short name in my hosts or the FQDN. I'm connecting with a 50mbps (cable, sync) connection so that doesn't appear to be the problem, and when I do finally get a connection then it's a good, quick, stable one. I have tried listening on another port (8000) and that makes no difference. Web and other connections from the laptop to the machine are also very good. Does anyone have any ideas here?

  • With Ubuntu 12.04 unlike 11.04 Wine installed application start menu links are missing

    - by Ron Whites
    With Ubuntu 12.04 and wine 1.4 unlike ubuntu 11.04 with wine 1.2.2 installed application start menu links are missing. For instance with Ubuntu 11.04 including Wine I can install one of our Windows applications and then can go to Applications Wine Programs Semantic Designs TestCoverage Documentation to bring up the documentation for how to run our tool. Unfortunately with Ubuntu 12.04 the Applications menu is gone and going to Dash I do see "Recent Apps and more apps" but my installed Wine application and related documentation link is shown present, even though the wine uninstaller shows in present. I found this online suggestion and tried using the gnome "main menu"... Windows key to launch the Dash. Enter "Main Menu" in the search field and open the old Edit Main Menu app. Select the Category (aka Unity Dash Filter) you want the item in. Name the Dash/Launcher Item Add the Command to launch said app With "mainmenu" then get down to the TestCoverage Documentation and I could see a command link in properties of .. env WINEPREFIX="/home/sdtest/.wine" wine C:\windows\command\start.exe /Unix /home/sdtest/.wine/dosdevices/c:/users/sdtest/Start\ Menu/Programs/Semantic\ Designs/Test\ Coverage/Java\ 1.7\ Documentation.lnk BUT I could not execute this link to view the installed documentation. So I copied the link properties into a file, set it as executable, and ran it as a bash script and the documentation came up! So why can't I use this link under main menu?

  • Grub Autostart with timeout

    - by BetaRide
    On Ubuntu 10.4 LTS I want Grub to start the default OS after 5 Seconds. I'd like to see the output of the startup scripts. Currently grub wait forever until I hit return and the output of the startup scripts isn't visible. Can someone tell me how I have to configure /etc/default/grub or any other setups? I tried to play with GRUB_TIMEOUT and GRUB_DEFAULT and did a sudo update-grub afterwards, but nothing changed. Any ideas? # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=5 #GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_SAVEDEFAULT=true # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux # GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_LINUX_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"

  • Disk (EXT4) suddenly empty without any sign of why

    - by Ohnomydisk
    I have a Ubuntu 10.04 server with several disks in it. The disks are setup with a union filesystem, which presents them all as one logical /home. A few days ago, one of the disks appears to have suddenly 'become empty', for lack of better explanation. The amount of data on the /home mount almost halved within minutes - the disk appears to have had just over 400 GB of data prior to 'becoming empty'. I have absolutely no idea what happened. I was not using the server at the other time, but there are half a dozen other users who may have been (without root access and without the ability to hose a whole disk). I've ran SMART tests on the disk and it comes back clean. The filesystem checks fine (it has 12 GB used now, as some user software continued downloading after the incident). All I know is that around around midnight on October 19, the disk usage changed dramatically: The data points are every 15 minutes, and the full loss occured between captures: 2012-10-18 23:58:03.399647 - has 953.97/2059.07 GB [46.33 percent] 2012-10-19 00:13:15.909010 - has 515.18/2059.07 GB [25.02 percent] Other than that, I have not much to go off :-( I know that: There's nothing interesting in log files at that time Nobody appeared to be logged in via SSH at the time it occured (most users do not even use SSH) The server was online through whatever occured (3 months uptime) None of the other disks were affected and everything else on the server looks completely normal I have tried using "extundelete" on the disk and it didn't really find anything (some temporary files, but they looked new anyway) I am completely at a loss to what could have caused this. I was initially thinking maybe root escalation exploit, but even if someone did maliciously "rm" the disk contents, it would take more than 15 minutes for 400 GB?

  • Apache Virtualhosts with PHP and custom logs - how to isolate PHP errors?

    - by Repox
    I'm trying to setup a simple hosting enviroment for my application on an Ubuntu server. I created a virtualhost like this: <VirtualHost *:80> ServerAdmin [email protected] ServerName www.example.com ServerAlias example.com DocumentRoot /home/owner/example.com/docs <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/owner/example.com/docs/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /home/owner/example.com/logs/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog /home/owner/example.com/logs/access.log combined php_flag log_errors on php_value error_log /home/owner/example.com/logs/php-error.log </VirtualHost> Now, my problem is that PHP errors and warnings are thrown in the error.log - not the php-error.log as I was hoping. How can achieve this?

  • Multiple SSL certificates on one server

    - by Kyle O'Brien
    We're hosting two websites on our fairly tiny but dedicated production server. Both website require SSL authentication. So, we have virtualhosts set up for both of them. They both reference their own domain.key, domain.crt and domain.intermediate.crt files. Each CSR and certificate file for each site was setup using its own unique information and nothing is shared between them (other than the server itself) However, which ever site's symbolic link (set up in /etc/apache2/sites-enabled) is reference first, is the site who's certificate is referenced even if we're visiting the second site. So for example, assume our companies are Cadbury and Nestle. We set up both sites with their own certificates but we create Cadbury's symbolic link in apache's site-enabled folder first and then Nestle's. You can visit Nestle perfectly fine but if you check the certificate installation, it reference's Cadbury's certificate. We're hosting these websites on a dedicated Ubuntu 12.04.3 LTS server. Both certificates are provided by Thawte.com. I came across a few potential solutions with no degree of success. I'm hoping someone else has a decent solution? Thanks Edit: The only other solution that seems to have provided success to some people is using SNI with Apache. However, the setups here didn't seem to coincide with our setup at all.
