  • Icinga error "Icinga Startup Delay does not exist" although it does

    - by aaron
    I just installed icinga to monitor my server following this guide: http://docs.icinga.org/0.8.1/en/wb_quickstart-idoutils.html Everything built and installed correctly, but icinga is reporting a critical error with the reason: "The command defined for service Icinga Startup Delay does not exist" However, I can see that ${ICINGA_BASE}/etc/objects/localhost.cfg contains: define service{ use local-service ; Name of service template to use host_name localhost service_description Icinga Startup Delay check_command check_icinga_startup_delay notifications_enabled 0 } and ${ICINGA_BASE}/etc/objects/commands.cfg contains: define command { command_name check_icinga_startup_delay command_line $USER1$/check_dummy 0 "Icinga started with $$(($EVENTSTARTTIME$-$PROCESSSTARTTIME$)) seconds delay | delay=$$(($EVENTSTARTTIME$-$PROCESSSTARTTIME$))" } both of these files had not been modified since the whole make/install process. I am running on Ubuntu 10.04, most recent build of icinga-core, and apache2 2.2.14 What must I do to tell Icinga that the command exists? Or is the problem that check_dummy does not exist? Where or how would I define that?

  • Need to add request headers to every request in Apache

    - by 115748146017471869327
    I'm trying to add a header value to every request via Apache (ver 2.2). I've edited my VirtualHost to include the following vaiations: (I've tried both RequestHeader and Header, add and set in all of these cases) RequestHeader set X-test_url "Test" or <Directory /> RequestHeader set X-test_url "Test" </Directory> or <Location ~ "/*" > RequestHeader set X-test_url "Test" </Location> It's hard to explain how I've gotten to this point, but I have to get this done in Apache. Again I'm trying to add the header value to every request. Thanks.

  • DNAT to 127.0.0.1 with iptables / Destination access control for transparent SOCKS proxy

    - by cdauth
    I have a server running on my local network that acts as a router for the computers in my network. I want to achieve now that outgoing TCP requests to certain IP addresses are tunnelled through an SSH connection, without giving the people from my network the possibility to use that SSH tunnel to connect to arbitrary hosts. The approach I had in mind until now was to have an instance of redsocks listening on localhost and to redirect all outgoing requests to the IP addresses I want to divert to that redsocks instance. I added the following iptables rule: iptables -t nat -A PREROUTING -p tcp -d 1.2.3.4 -j DNAT --to-destination 127.0.0.1:12345 Apparently, the Linux kernel considers packets coming from a non-127.0.0.0/8 address to an 127.0.0.0/8 address as “Martian packets” and drops them. What worked, though, was to have redsocks listen on eth0 instead of lo and then have iptables DNAT the packets to the eth0 address instead (or using a REDIRECT rule). The problem about this is that then every computer on my network can use the redsocks instance to connect to every host on the internet, but I want to limit its usage to a certain set of IP addresses only. Is there any way to make iptables DNAT packets to 127.0.0.1? Otherwise, does anyone have an idea how I could achieve my goal without opening up the tunnel to everyone? Update: I have also tried to change the source of the packets, without any success: iptables -t nat -A POSTROUTING -p tcp -s 192.168.1.0/24 -d 1.2.3.4 -j SNAT --to-source 127.0.0.1 iptables -t nat -A POSTROUTING -p tcp -s 192.168.1.0/24 -d 127.0.0.1 -j SNAT --to-source 127.0.0.1

    - by Mark Renouf
    Hi... I need some help with partman-auto custom recipe in preseed.... it's doing unexpected things, the docs aren't so clear.

The application is runnning on a rhel5 os and Im not very familiar with the memory management system. Would appreciate if someone clould tell me what extactly is the Ureclaim space and why it is increasing in sync with the close_wait.

  • Security permissions for remote shared folders

    - by Tomas Lycken
    I have two servers running Windows Server 2003, and I want copy files from one server (A), programmatically with a windows service running under the Local System account, to a shared folder on the other (B). I keep getting "access denied" errors, and I can't figure out what security settings I need to set to open the shared folder for writing. This is what I've done on the recieving end: On A, right-click on the folder to share, choose the tab "Sharing" and select "Share this folder". Set a share name. Click "Permissions", add the group "Everyone" and give it full control. I tried choosing the "Security" tab to give some permissions there as well, but the "Add" dialog only finds local users, despite the fact that B shows up in the "Workgroup computers" dialog. After further inspection, this is the case also for the "Permissions" dialog under the "Sharing" tab (are they the same?).

  • Synology DS210j & online backup: what do people recommend?

    - by Dean
    I've just purchased a Synology DS210j for my home network and would like to backup this NAS online. I noticed that DiskStation Manager v2.3 provides various options including Amazon S3 and rsync: Does anybody have some real usage against cost statistics for Amazon's S3 service? How is sensitive data protected on Amazon S3? Are there any rsync online backup options? If so, what do people recommend? UPDATE: I am still unable to find any decent answers to the above questions, can anybody help me out?

  • Single Msi File - Many RemoteApps

    - by Mikeon
    How can I create a single .MSI installer file for many Remote Apps in Remote Desktop Services? Suppose I have 10 applications exposed via RDS. To make life easier I created MSI installer packages so users can "install" those apps. currently I have 10 different .msi files which forces users to install 10 times. Is it possible to make all/some apps into a single .msi file? (I don't control user machines so installing via GPO or other magic is out of question).

  • setting domains

    - by allenskd
    I'm setting a local webserver to do a lot of web development work from now on. I'm not really knowledgeable in hosting configuration. Thing is I just added mydomain.com in /etc/hosts that's fine but what's the next step? TI need to use the wildcard on *.mydomain.com, so I'm figuring I need to add my zone in bind, is this correct? so I can make use of virtual hosts in apache and in play-framework Everything will be local, but once in a while I want to make public of my webserver to certain people using the no-ip service, in windows I've done it, in linux I don't know if it's any difference. The question is pretty much if I'm configuring it right or not? If this sounds confusing let me know, I'll try to detail it more

  • Using SSL with Openfire

    - by Dan
    I'm having a rough time getting SSL configured properly on an Openfire install. Quite honestly, I just don't know what to do. It seems convoluted on the steps necessary to get a cert imported. Has anyone out there successfully done this? I'm running Openfire 3.6.4 on Server2003 R2. I have a signed UC cert which is ready to roll, I just don't know what to do with it. I've been through tons of tutorials on converting from .crt to .der to .pem, using openssl and java tools, but its only getting more confusing as I go.

  • Using naked domain in apache, no "www" on domain in httpd.conf

    - by chrsdgtl
    Incredibly there is no good tutorial or easy reference guide for using naked domains (no subdomain) as the primary URI online that I could find. I'm trying to configure this to happen in my httpd.conf in apache. Since I'm still a relative newb to this server stuff, trying to figure it out myself all I could do was configure some nasty redirect loops and error 400's. There's plenty of notes for the more common: http:// -- https:// and naked to -- www. and a ton of .htaccess stuff (not interested) What I want is http://www.domain.com -- http://domain.com The most helpful thing I found was this: Multiple domains (including www-"subdomain") on apache? I ended using the solution mentioned by ceejayoz in that post that some folks noted was messy and complicated because it got the desired result but I'd like to know the best practice for this in the future. I'd appreciate a nudge in the right direction. Thanks in advance.

  • IMAP email migration from Apptix to Office 365

    - by npiani
    I am having issues setting up a migration from Apptix to Office 365 of 41 users in my company. I've found a couple guides on the Microsoft website about how to do it (Thank you Google) but I keep coming up with problems. I am trying to set up a mailbox migration through IMAP to get all of my users' emails over to Office 365 before we make the transition over from Apptix. One of the forums suggested using IMAP, since a CSV file can be uploaded to Office 365 and it will check for incoming mail for each user every 24 hours. My problem is that when I do this, I just get errors. The link I got was this: http://help.outlook.com/en-us/140/ms.exch.ecp.emailmigrationstatuslearnmore.aspx#imap I was wondering if anyone has successfully managed this transition. I'm using imap.apptixemail.net as the IMAP server (FQDN) Thank you for the help in advance. Any help or push in the right direction would be amazing

  • Who uses Zimbra Collaboration Suite and why?

    - by AlberT
    I am really curious about other people experiences and choices. After a long scouting, I found ZCS to be a really impressive solution, maybe the only real alternative to M$ Exchange. I'm very interested in opinions and case histories from users having already deployed Zimbra on their infrastructure or planning to do it. Both Community and Network edition cases are appreciated, pro and cons explained too :) Zimlets, addons, useful skins, Zimbra Desktop and other apps or mobile integration use case too of course.

  • Login box not shown on Ubuntu

    - by Alexandre
    I've installed Ubuntu 10.04 (64bit) as a guest OS in VirtualBox, using Windows7 Professional (64bit) as host. After Ubuntu install, I did installed Xfce4 (sudo apt-get install xfce4). Logged in using a Xfce session, and when I logged out, I couldn't see the login box anymore, only the regular gnome background from login screen. Then I restarted the virtual machine, and now I'm not able to see the login box anymore, only the gnome background. Does someone knows how to solve this? Thanks in advance Update: I've tried to use Xubuntu, that comes with Xfce. And I'm facing the same problem. As a common denominator from the two cases, now I see the problem arises after I've updated the system, and then installed curl (via apt-get), zlib (make process), git (make process). But I'm not sure this can be the cause for this ... Update: I isolated the problem. The bad guy is zlib, but I don't have a clue why. In fact, it does crash not only ubuntu and xubuntu, but also Debian (Yes, I've tested all). I'll keep this question in case someone have the same problem, but I think my initial question is not valid anymore.

  • Postfix on IspCP cannot send to google apps mail if it is in the same domain

    - by Evan Sap
    In my vps setup I have ispcp omega 1.0.7 installed. Everything works fine except the fact that postfix cannot send to google apps mail when the domain of google apps is also registered in ispcp. Postfix sends an email to normal addresses (hotmail, yahoo, gmail etc). I use external dns. There is also a discussion I started in the ispcp forum here .mail.log file provides these messages: mail for exampledomain.gr loops back to myself". postfix/bounce: sender non-delivery notification. postfix/qmgr: removed Any help would be appreciated.

  • What can cause an increase in inactive memory and how to reclame it?

    - by Boaz
    Hi All, I have heavy application running on a CentOS server and I'm seeing a strange memory behavior. Here is a snapshot of a munin graph: As you can see the amount of committed memory increases gradually causing the swap file to be use. What strikes me odd is that the amount of inactive memory keeps growing as well. It is my understanding that the inactive memory is actually memory freed up but not yet clean by the OS and put back in the free memory pool. It seems that running out of memory is acutally caused by this lack of clean up, but I may be wrong. Can you give some tips to find the cause of the problem and/or cause CentOS to reclaim the inactive memory? Thanks. Some extra info: 1) I have a tmpfs mounted on /tmp and the number of files stored there grows (but it is double the amount of the inactive memory). 2) cat /proc/meminfo (at a later stage than the image) gives: MemTotal: 14371428 kB MemFree: 1207108 kB Buffers: 35440 kB Cached: 4276628 kB SwapCached: 785316 kB Active: 9038924 kB Inactive: 3902876 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 14371428 kB LowFree: 1207108 kB SwapTotal: 10223608 kB SwapFree: 6438320 kB Dirty: 627792 kB Writeback: 0 kB AnonPages: 7844560 kB Mapped: 49304 kB Slab: 146676 kB PageTables: 27480 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 17409320 kB Committed_AS: 16471488 kB VmallocTotal: 34359738367 kB VmallocUsed: 275852 kB VmallocChunk: 34359462007 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 Hugepagesize: 2048 kB

  • DNS Round-robin failover and load balancing

    - by Tom O'Connor
    Having read all of the questions and answers (1 2 3 and so on) on here relating to DNS load balancing, and Round-robin DNS, there's still a number of unanswered questions.. Large companies, and I'm looking at Google, Facebook and Twitter here, do present multiple A records. 1) If DNS loadbalancing/failover is so dodgy, why do large organisations do it? There seems to be very little mention of "DNS Pinning", despite this (PDF) paper about it. 2) Why is DNS Pinning so seldom mentioned? 3) Are there any concrete examples of which ISPs and so on actually do rewrite DNS TTLs? That said, I'm not entirely backing the side for using DNS for failover or any form of load balancing. For most networks, BGP diverse routing still seems to be a better fit. DNS rears it's ugly head again. :(

  • aliasing "git" ssh login to "gitolite"

    - by Randal Schwartz
    I'm installing gitolite from CentOS packages for my client. The package creates a gitolite user, which will be visible explicitly during a "git clone" operations. The client wants to use "git" and not "gitolite", in case we change to something more fancy later. I'm not very familiar with CentOS, so I don't want to try to build the package myself from source. I'm wondering if there's a way to do one of the following: Trick sshd into treating "git" as "gitolite". Somehow "alias" a new git username to be the same in all ways as the existing gitolite username (perhaps through some complex combinations of useradd). Rename the "gitolite" username to "git" without upsetting later yum update operations Something else that I hadn't thought of I'd appreciate detailed instructions or pointers.

  • Windows NT from vmware to kvm

    - by Luca Rossi
    I'm trying to convert a couple of old Windows NT virtual servers from vmware to KVM. I tried almost all guidelines and how to I found around the web but with no luck. I have the vmware virtual disk: Dlc1.vmdk partitioned image. I converted the vmdk into qcow2 image with the qemu utility and I tried to use it with kvm: kvm -hda test.qemu -vnc :1 -m 750 but I receive "error loading operating system" I also tried with raw partitions I can mount through losetup and kpartx. but nothing changed I also tried to create an brand new image file with: qemu-img create -f qcow2 test.qcow2 2G I partitioned the new image file and I copied the original partition 1 to the new partition 1 with dd: dd if=/dev/mapper/loop1p1 of=/dev/mapper/loop0p1 bs=128M no luck again I also tried with a single unpartitioned file: qemu-img create -f qcow2 test.qcow2 2G and I copied the partition 1 to the new image file: dd if=/dev/mapper/loop0p1 of=test.img bs=128M but when booting, I receive a black screen and the virtual machine hangs. The bootloader is loaded successfully, because I also tried with a GRUB live iso and I receive the same screens and errors. Note that grub sees the Windows setup and give me the boot choice. I have the suspect the problem is that the vmware machine is probably a scsi guest and in centos 6 (my system) scsi emulation is no longer supported. But in that case, where to change in Windows? I'm not so skilled with MS systems. Thank you for the help Luca Rossi
