  • Wake On Lan only works on first boot, not sequent ones

    - by sp3ctum
    I have converted my old Dell Latitude D410 laptop to a server for tinkering. It is running an updated Debian Squeeze (6) with a Xen enabled kernel (I want to toy with virtual machines later on). I am running it 'headless' via an ethernet connection. I am struggling to enable Wake On Lan for the box. I have enabled the setting in the BIOS, and it works nicely, but only for the first time after the power cord is plugged in. Here is my test: Plug in power cord, don't boot yet Send magic Wake On Lan packet from test machine (Ubuntu) using the wakeonlan program Server expected to start (does every time) Once server has booted, log in via ssh and shut it down via the operating system After shutdown, wake server up via WOL again (fails every time) Some observations: Right after step 1 I can see the integrated NIC has a light on. I deduce this means the NIC gets adequate power and that the ethernet cable is connected to my switch. This light is not on after step 4 (the shutdown stage). The light becomes back on after I disconnect and reconnect the power cord, after which WOL works as well. After step 4 I can verify that wake on lan is enabled via the ethtool program (repeatable each time) This blog post suggested the problem may lay in the fact the motherboard might not be giving adequate power to the NIC after shutdown, so I copied an acpitool script that supposedly should signal the system to give the needed power to the card when shut down. Obviously it did not fix my issue. I have included the relevant power settings in the paste below. I have tried different combinations of parameters of shutdown (the program) options, as well as the poweroff program. I even tried "telinit 0", which I figured would do the most direct boot via software. If I keep the laptop's power button pressed down and do a hard boot this way, the light on the ethernet port stays lit and a WOL is possible. I copied a bunch of hopefully useful information in this paste I have tried this with the laptop battery connected and without it. I get the same result. Promptly pressing the power button causes the system to shut down with the message "The system is going down for system halt NOW!", and WOL is still unsuccessful.

  • recommendations for efficient offsite remote backup solution of vm's

    - by senorsmile
    I am looking for recommendations for backing up my current 6 vm's(and soon to grow to up to 20). Currently I am running a two node proxmox cluster(which is a debian base using kvm for virtualization with a custom web front end to administer). I have two nearly identical boxes with amd phenom II x4's and asus motherboards. Each has 4 500 GB sata2 hdd's, 1 for the os and other data for the proxmox install, and 3 using mdadm+drbd+lvm to share the 1.5 TB's of storage between the two machines. I mount lvm images to kvm for all of the virtual machines. I currently have the ability to do live transfer from one machine to the other, typically within seconds(it takes about 2 minutes on the largest vm running win2008 with m$ sql server). I am using proxmox's built-in vzdump utility to take snapshots of the vm's and store those on an external harddrive on the network. I then have jungledisk service (using rackspace) to sync the vzdump folder for remote offsite backup. This is all fine and dandy, but it's not very scalable. For one, the backups themselves can take up to a few hours every night. With jungledisk's block level incremental transfers, the sync only transfers a small portion of the data offsite, but that still takes at least a half an hour. The much better solution would of course be something that allows me to instantly take the difference of two time points (say what was written from 6am to 7am), zip it, then send that difference file to the backup server which would instantly transfer to the remote storage on rackspace. I have looked a little into zfs and it's ability to do send/receive. That coupled with a pipe of the data in bzip or something would seem perfect. However, it seems that implementing a nexenta server with zfs would essentially require at least one or two more dedicated storage servers to serve iSCSI block volumes (via zvol's???) to the proxmox servers. I would prefer to keep the setup as minimal as possible (i.e. NOT having separate storage servers) if at all possible. I have also briefly read about zumastor. It looks like it could also do what I want, but it appears to have halted development in 2008. So, zfs, zumastor or other?

  • Apache ProxyPass Missing Images

    - by EpicOfChaos
    I have a apache server that sits in front of my glassfish server. mydomain.com goes directly to my static files on apache, than if you hit the subdomain forum.mydomain.com it goes to the glassfish webapp forum/ at 127.0.0.1:8080/forum/. This proxy seems to work it takes me to the web app but all of the images are missing! Here is how I go my virtual host setup.

Standards, remediation, cohesion...all fancy foreign words to me. ============== How am I supposed to deal with / filesystem full issues across multiple platforms that have a devastating number of mounts? On Red Hat el5, du -x apparently avoids traversal into other filesystems. While this may be so, it does not appear to do anything if run from the / directory. On Solaris 10, the equivalent flag is du -d, which apparently packs no surprises, allowing Sun to uphold its legacy of inconvenience effortlessly. (I'm hoping I've just been doing it wrong.) I offer up for sacrifice my Frankenstein's monster. Tell me how ugly it is. Tell me I should download forbidden 3rd party software. Tell me I should perform unauthorized coreutils updates, piecemeal, across 2000 systems, with no single sign-on, no authorized keys, and no network update capability. Then, please help me make this bastard better: pwd / du * | egrep -v "$(echo $(df | awk '{print $1 "\n" $5 "\n" $6}' | \ cut -d\/ -f2-5 | egrep -v "[0-9]|^$|Filesystem|Use|Available|Mounted|blocks|vol|swap")| \ sed 's/ /\|/g')" | egrep -v "proc|sys|media|selinux|dev|platform|system|tmp|tmpfs|mnt|kernel" | \ cut -d\/ -f1-2 | sort -k2 -k1,1nr | uniq -f1 | sort -k1,1n | cut -f2 | xargs du -shx | \ egrep "G|[5-9][0-9]M|[1-9][0-9][0-9]M" My biggest failure and regret is that it still requires a single character edit for Solaris: pwd / du * | egrep -v "$(echo $(df | awk '{print $1 "\n" $5 "\n" $6}' | \ cut -d\/ -f2-5 | egrep -v "[0-9]|^$|Filesystem|Use|Available|Mounted|blocks|vol|swap")| \ sed 's/ /\|/g')" | egrep -v "proc|sys|media|selinux|dev|platform|system|tmp|tmpfs|mnt|kernel" | \ cut -d\/ -f1-2 | sort -k2 -k1,1nr | uniq -f1 | sort -k1,1n | cut -f2 | xargs du -shd | \ egrep "G|[5-9][0-9]M|[1-9][0-9][0-9]M" This will exclude all non / filesystems in a du search from the / directory by basically munging an egrepped df from a second pipe-delimited egrep regex subshell exclusion that is naturally further excluded upon by a third egrep in what I would like to refer to as "the whale." The munge-fest frantically escalates into some xargs du recycling where -x/-d is actually useful, and a final, gratuitous egrep spits out a list of directories that almost feels like an accomplishment: Linux: 54M etc/gconf 61M opt/quest 77M opt 118M usr/ ##===\ 149M etc 154M root 303M lib/modules 313M usr/java ##====\ 331M lib 357M usr/lib64 ##=====\ 433M usr/lib ##========\ 1.1G usr/share ##=======\ 3.2G usr/local ##========\ 5.4G usr ##<=============Ascending order to parent 94M app/SIP ##<==\ 94M app ##<=======Were reported as 7gb and then corrected by second du with -x. Solaris: 63M etc 490M bb 570M root/cores.ric.20100415 1.7G oec/archive 1.1G root/packages 2.2G root 1.7G oec Guess what? It's really slow. Edit: Are there any bash one-liner heroes out there than can turn my bloated abomination into divine intervention, or at least something resembling gingerly copypasta?

  • How should I set up my Hyper-V server and network topology?

    - by Daniel Waechter
    This is my first time setting up either Hyper-V or Windows 2008, so please bear with me. I am setting up a pretty decent server running Windows Server 2008 R2 to be a remote (colocated) Hyper-V host. It will be hosting Linux and Windows VMs, initially for developers to use but eventually also to do some web hosting and other tasks. Currently I have two VMs, one Windows and one Ubuntu Linux, running pretty well, and I plan to clone them for future use. Right now I'm considering the best ways to configure developer and administrator access to the server once it is moved into the colocation facility, and I'm seeking advice on that. My thought is to set up a VPN for access to certain features of the VMs on the server, but I have a few different options for going about this: Connect the server to an existing hardware firewall (an old-ish Netscreen 5-GT) that can create a VPN and map external IPs to the VMs, which will have their own IPs exposed through the virtual interface. One problem with this choice is that I'm the only one trained on the Netscreen, and its interface is a bit baroque, so others may have difficulty maintaining it. Advantage is that I already know how to do it, and I know it will do what I need. Connect the server directly to the network and configure the Windows 2008 firewall to restrict access to the VMs and set up a VPN. I haven't done this before, so it will have a learning curve, but I'm willing to learn if this option is better long-term than the Netscreen. Another advantage is that I won't have to train anyone on the Netscreen interface. Still, I'm not certain if the capabilities of the Windows software firewall as far as creating VPNs, setting up rules for external access to certain ports on the IPs of Hyper-V servers, etc. Will it be sufficient for my needs and easy enough to set up / maintain? Anything else? What are the limitations of my approaches? What are the best practices / what has worked well for you? Remember that I need to set up developer access as well as consumer access to some services. Is a VPN even the right choice?

  • How to force Debian to boot new Kernel?

    - by ThE_-_BliZZarD
    I'm running Debian 6, Debian GNU/Linux, with Linux 2.6.32-5-amd64 under Grub2 ( 1.98+20100804-14+squeeze1) on a remote system (no possibility to view the pre-boot messages). I compiled and installed a new kernel, but I can not get it to boot. What I have done: Installed the packages via: dpkg -i linux-headers-3.5.3.20120914-amd64_3.5.3.20120914-amd64-10.00.Custom_amd64.deb linux-image-3.5.3.20120914-amd64_3.5.3.20120914-amd64-10.00.Custom_amd64.deb This updated the Grub configuration. My /boot/grub/grub.cfg now contains: menuentry 'Debian GNU/Linux, with Linux 3.5.3.20120914-amd64' --class debian --class gnu-linux --class gnu --class os { insmod raid insmod mdraid insmod part_msdos insmod part_msdos insmod ext2 set root='(md0)' search --no-floppy --fs-uuid --set 5a3882a9-c7df-4f6a-9feb-f03e3e37be01 echo 'Loading Linux 3.5.3.20120914-amd64 ...' linux /vmlinuz-3.5.3.20120914-amd64 root=UUID=003242b5-121b-49f3-b32f-1b40aea56eed ro acpi=ht quiet panic=10 echo 'Loading initial ramdisk ...' initrd /initrd.img-3.5.3.20120914-amd64 } menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-amd64' --class debian --class gnu-linux --class gnu --class os { insmod raid insmod mdraid insmod part_msdos insmod part_msdos insmod ext2 set root='(md0)' search --no-floppy --fs-uuid --set 5a3882a9-c7df-4f6a-9feb-f03e3e37be01 echo 'Loading Linux 2.6.32-5-amd64 ...' linux /vmlinuz-2.6.32-5-amd64 root=UUID=003242b5-121b-49f3-b32f-1b40aea56eed ro acpi=ht quiet panic=10 echo 'Loading initial ramdisk ...' initrd /initrd.img-2.6.32-5-amd64 } I used grub-set-default "Debian GNU/Linux, with Linux 2.6.32-5-amd64" to set the old kernel as default and then grub-reboot "Debian GNU/Linux, with Linux 3.5.3.20120914-amd64" to boot into the new kernel once. After update-grub I rebooted the system, but everytime it comes back up with the old kernel (2.6). I tried setting the new one as default (grub-set-default 0, update-grub, reboot) but, still the old one. The Syslogs contain NO hint whatsoever about trying to boot the new kernel - only the old one. Would there be any hints regarding problems with a kernel? Is there a way to enable debug-logging in grub? What am I doing wrong? How can I force the system to boot the new kernel?

  • Problem upgrading kernel on debian 3.1

    - by exhuma
    Hi, I have a quite old box in a remote server farm. So I have no direct access. Only remote SSH (and via SSH to a serial console). I haven't updated this box in ages. Now, whenever I want to install a new package, a dependency to glibc appears. Unfortunately, the install of glibc depends on a 2.6 kernel and I am running a venerable 2.4 kernel (one more reason to upgrade). The problem is, that the install of a new kernel has an indirect (over locales) dependency to glibc. So, to install glibc, I need a new kernel. For a new kernel, I need to upgrade glibc. Essentially I am blocked. What's the best way to proceed considering I have no "hardware" access? Here's a quick transcript of the upgrade process: [green:~]% sudo aptitude install linux-image-686 Reading Package Lists...

In that case, please add etch sources to your /etc/apt/sources.list and run: apt-get install -t etch linux-image-2.6 Then reboot into this new kernel, and proceed with your upgrade dpkg: error processing /var/cache/apt/archives/libc6_2.7-18lenny2_i386.deb (--unpack): subprocess pre-installation script returned error exit status 1 Errors were encountered while processing: /var/cache/apt/archives/libc6_2.7-18lenny2_i386.deb E: Sub-process /usr/bin/dpkg returned an error code (1) Ack!

  • unable to join domain using virtualbox

    - by FreshPrinceOfSO
    I'm in the process of setting up a VM environment for a MS certification exam (70-462). Following the training kit's instructions, I've set up a domain controller (DC) and two members (SQL-A, SQL-B) thus far. I can't figure out why I can't join the domain. DC IPv4 Address . . . : 10.10.10.10(Preferred) Subnet Mask. . . . : 255.0.0.0 DNS Servers. . . . : ::1 127.0.0.1 SQL-A IPv4 Address . . . : 10.10.10.20(Preferred) Subnet Mask. . . . : 255.0.0.0 DNS Servers. . . . : 10.10.10.10 SQL-B IPv4 Address . . . : 10.10.10.30(Preferred) Subnet Mask. . . . : 255.0.0.0 DNS Servers. . . . : 10.10.10.10 I've read how to do networking between virtual machines in virtualbox and the documentation. After trying various network adapter configurations, I can't get them to communicate in order to have the two members join the domain. When I ping from .30 to .10, I get: ping 10.10.10.10 Pinging 10.10.10.10 with 32 bytes of data: Reply from 10.10.10.20: Destination host unreachable.

  • Why do my Application Compatibility Toolkit Data Collectors fail to write to my ACT Log Share?

    - by Jay Michaud
    I am trying to get the Microsoft Application Compatibility Toolkit 5.6 (version 5.6.7320.0) to work, but I cannot get the Data Collectors to write to the ACT Log Share. The configuration is as follows. Machine: ACT-Server Domain: mydomain.example.com OS: Windows 7 Enterprise 64-bit Edition Windows Firewall configuration: File and Printer Sharing (SMB-In) is enabled for Public, Domain, and Private networks ACT Log Share: ACT Share permissions*: Group/user names Allow permissions --------------------------------------- Everyone Full Control Administrator Full Control Domain Admins Full Control Administrators Full Control ANONYMOUS LOGON Full Control Folder permissions*: Group/user name Allow permissions Apply to ------------------------------------------------- ANONYMOUS LOGON Read, write & execute This folder, subfolders, and files Domain Admins Full control This folder, subfolders, and files Everyone Read, write & execute This folder, subfolders, and files Administrators Full control This folder, subfolders, and files CREATOR OWNER Full control Subfolders and files SYSTEM Full control This folder, subfolders, and files INTERACTIVE Traverse folder / This folder, subfolders, and files execute file, List folder / read data, Read attributes, Read extended attributes, Create files / write data, Create folders / append data, Write attributes, Write extended attributes, Delete subfolders and files, Delete, Read permissions SERVICE (same as INTERACTIVE) BATCH (same as INTERACTIVE) *I am fully aware that these permissions are excessive, but that is beside the point of this question. Some of the clients running the Data Collector are domain members, but some are not. I am working under the assumption that this is a Windows file sharing permission issue or a network access policy issue, but of course, I could be wrong. It is my understanding that the Data Collector runs in the security context of the SYSTEM account, which for domain members appears on the network as MYDOMAIN\machineaccount. It is also my understanding from reading numerous pieces of documentation that setting the ANONYMOUS LOGON permissions as I have above should allow these computer accounts and non-domain-joined computers to access the share. To test connectivity, I set up the Windows XP Mode virtual machine (VM) on ACT-Server. In the VM, I opened a command prompt running as SYSTEM (using the old "at" command trick). I used this command prompt to run explorer.exe. In this Windows Explorer instance, I typed \ACT-Server\ACT into the address bar, and then I was prompted for logon credentials. The goal, though, was not to be prompted. I also used the "net use /delete" command in the command prompt window to delete connections to the ACT-Server\IPC$ share each time my connection attempt failed. I have made sure that the appropriate exceptions are Since ACT-Server is a domain member, the "Network access: Sharing and security model for local accounts" security policy is set to "Classic - local users authenticate as themselves". In spite of this, I still tried enabling the Guest account and adding permissions for it on the share to no effect. What am I missing here? How do I allow anonymous logons to a shared folder as a step toward getting my ACT Data Collectors to deposit their data correctly? Am I even on the right track, or is the issue elsewhere?

  • Mercurial browser on Windows 2003 takes several refreshes before displaying repositories

    - by Tim Murphy
    When attempt to browse my Mercurial repositories it usually takes several refreshes before the repository list is displayed. The configuration is as follows: Windows Server 2003 (Dedicated machine hosted by http://www.server4you.com/. Site has anonymous password protection with self-signed SSL.

Other problems with the repository server: Before doing a clone/push/etc I have to browse the repositories first otherwise hg on my local machine can not locate the site. I have one a repository with a large changeset that after a minute or so throw error "abort: error: An existing connection was forcibly closed by the remote host".

  • Postfix flow/hook reference, or high-level overview?

    - by threecheeseopera
    The Postfix MTA consists of several components/services that work together to perform the different stages of delivery and receipt of mail; these include the smtp daemon, the pickup and cleanup processes, the queue manager, the smtp service, pipe/spawn/virtual/rewrite ... and others (including the possibility of custom components). Postfix also provides several types of hooks that allow it to integrate with external software, such as policy servers, filters, bounce handlers, loggers, and authentication mechanisms; these hooks can be connected to different components/stages of the delivery process, and can communicate via (at least) IPC, network, database, several types of flat files, or a predefined protocol (e.g. milter). An old and very limited example of this is shown at this page. My question: Does anyone have access to a resource that describes these hooks, the components/delivery stages that the hook can interact with, and the supported communication methods? Or, more likely, documentation of the various Postfix components and the hooks/methods that they support? For example: Given the requirement "if the recipient primary MX server matches 'shadysmtpd', check the recipient address against a list; if there is a match, terminate the SMTP connection without notice". My software would need to 1) integrate into the proper part of the SMTP process, 2) use some method to perform the address check (TCP map server? regular expressions? mysql?), and 3) implement the required action (connection termination). Additionally, there will probably be several methods to accomplish this, and another requirement would be to find that which best fits (ex: a network server might be faster than a flat-file lookup; or, if a large volume of mail might be affected by this check, it should be performed as early in the mail process as possible). Real-world example: The apolicy policy server (performs checks on addresses according to user-defined rules) is designed as a standalone TCP server that hooks into Postfix inside the smtpd component via the directive 'check_policy_service inet:127.0.0.1:10001' in the 'smtpd_client_restrictions' configuration option. This means that, when Postfix first receives an item of mail to be delivered, it will create a TCP connection to the policy server address:port for the purpose of determining if the client is allowed to send mail from this server (in addition to whatever other restrictions / restriction lookup methods are defined in that option); the proper action will be taken based on the server's response. Notes: 1)The Postfix architecture page describes some of this information in ascii art; what I am hoping for is distilled, condensed, reference material. 2) Please correct me if I am wrong on any level; there is a mountain of material, and I am just one man ;) Thanks!

  • Basic OpenVPN setup not working

    - by WalterJ89
    I am attempting to connect 2 win7 (x64+ x32) computers (there will be 4 in total) using OpenVPN. Right now they are on the same network but the intention is to be able to access the client remotely regardless of its location. The Problem I am having is I am unable to ping or tracert between the two computers. They seem to be on different subnets even though I have the mask set to 255.255.255.0. The server ends up as 10.8.0.1 255.255.255.252 and the client 10.8.0.6 255.255.255.252. And a third ends up as 10.8.0.10. I don't know if this a Windows 7 problem or something I have wrong in my config. Its a very simple set up, I'm not connecting two LANs. this is the server config (removed all the extra lines because it was too ugly) port 1194 proto udp dev tun ca keys/ca.crt cert keys/server.crt key keys/server.key # This file should be kept secret dh keys/dh1024.pem server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt client-to-client duplicate-cn keepalive 10 120 comp-lzo persist-key persist-tun status openvpn-status.log verb 6 this is the client config client dev tun proto udp remote thisdomainis.random.com 1194 resolv-retry infinite nobind persist-key persist-tun ca keys/ca.crt cert keys/client.crt key keys/client.key ns-cert-type server comp-lzo verb 6 Is there anything I missed in this? keys are all correct and the vpn's connect fine, its just the subnet or route issue. Thank You EDIT it seems on the server the openvpn-status.log has the routes for the client SERVER OpenVPN CLIENT LIST Updated,Wed May 19 18:26:32 2010 Common Name,Real Address,Bytes Received,Bytes Sent,Connected Since client,192.168.10.102:50517,19157,20208,Wed May 19 17:38:25 2010 ROUTING TABLE Virtual Address,Common Name,Real Address,Last Ref 10.8.0.6,client,192.168.10.102:50517,Wed May 19 17:38:56 2010 GLOBAL STATS Max bcast/mcast queue length,0 END Also this is from the client.log file: Which seems to be correct C:\WINDOWS\system32\route.exe ADD 10.8.0.0 MASK 255.255.255.0 10.8.0.5 Another EDIT 'route print' on the server shows the route: Destination Mask Gateway Interface 10.8.0.0 255.255.255.0 10.8.0.2 10.8.0.1 the same on the client shows 10.8.0.0 255.255.255.0 10.8.0.5 10.8.0.6 So the routes are there.. what can the problem be? Is there anything wrong with my configs? Why would OpenVPN be having problems communicating?

  • Impact of the L3 cache on performance - worth a dual-processor system?

    - by Dan Nissenbaum
    I will be purchasing a new high-end system, and I would like to have a better sense of whether a dual-processor Xeon system (I am looking at the new, high-end Xeon E5-2687W) might, realistically, provide a noticeable performance improvement due to the doubling of the L3 cache (20 MB per CPU). (This is in addition to the occasional added advantage due to the doubling of cores and RAM.) My usage scenario is, roughly, that I have many background applications running at any time - 3 or 4 data compression/backup applications, a low-impact web server, one or two virtual machines at any given time (usually fairly idle), and perhaps 20 utility programs that utilize a noticeable (but small) portion of the CPU cores. In total, when I am not actively using the computer, about 25% of the total CPU power is utilized in my current i7-970 6-core (12 thread) system. When I am doing routine work, the CPU utilization often exceeds 50%, and occasionally hits 75%-80%. The Xeon E5-2687W is not only a second-generation i7 (so should improve performance for that reason), but also has 8 cores (16 threads), rather than 6 cores. For this reason, I expect to run into the 75% CPU range even less frequently. Nonetheless, the ability to double the cores and the RAM is a consideration. However, in the end, I believe this decision comes down to whether the doubling of the L3 cache will provide a noticeable improvement. There are many benchmarks, and a lot of discussion, regarding CPU power. However, I find very little discussion of L3 cache utilization, and how increases in the L3 cache (such as doubling it with dual processors) affect performance. For example: If there are only two processes running, but each benefits from a large L3 cache (such as might be the case for background processes that frequently scan the file system), perhaps the overall system performance might noticeably improve with dual CPU's - even if only a single core is active on each CPU - due to each process having double the effective L3 cache. I am hoping that someone has a sense of the benefits of increasing (or doubling) the L3 cache size. Note: the CPU I am considering (the Xeon E5-2687W) has 20 MB L3 cache, so a system with dual CPU's would have 40 MB L3 cache.

  • load-causing processes disappearing from "top" ps -o pcpu shows bogus numbers

    - by Alec Matusis
    I administer a large number of servers, and I have this problem only with Ubuntu 10.04 LTS: I run a server under normal load (say load average 3.0 on an 8-core server). The "top" command shows processes taking certain % of CPU that cause this load average: say PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 11008 mysql 20 0 25.9g 22g 5496 S 67 76.0 643539:38 mysqld ps -o pcpu,pid -p11008 %CPU PID 53.1 11008 , everything is consistent. The all of the sudden, the process causing the load average disappears from "top", but the process continues to run normally (albeit with a slight performance decrease), and the system load average becomes somewhat higher. The output of ps -o pcpu becomes bogus: # ps -o pcpu,pid -p11008 %CPU PID 317910278 1587 This happened to at least 5 different severs (different brand new IBM System X hardware), each running different software: one httpd 2.2, one mysqld 5.1, and one Twisted Python TCP servers. Each time the kernel was between 2.6.32-32-server and 2.6.32-40-server. I updated some machines to 2.6.32-41-server, and it has not happened on those yet, but the bug is rare (once every 60 days or so).

  • WordPress 3.5 Multisite and nginx siteurl issues

    - by Florin Gogianu
    I'm setting up multisite on localhost in subdirectories. The problem is that when I'm trying to access the dashboard of a site I just created ( localhost/wptest/site/wp-admin ) I get "This webpage has a redirect loop" and when I try to access the actual website ( localhost/wptest/site ) the page loads but without assets, such as css. When I access the network dashboard, or the primary site dashboard on localhost/wptest everything is just fine. Also when I edit the permalink of the second site in the network dashboard, to be like this: localhost/site it also runs fine. How to make it work with the default permalink structure localhost/wptest/site? The wordpress files are in /usr/share/html/wptest The wp-config.php is as follows: define('WP_ALLOW_MULTISITE', true); define('MULTISITE', true); define('SUBDOMAIN_INSTALL', false); define('DOMAIN_CURRENT_SITE', 'localhost'); define('PATH_CURRENT_SITE', '/wptest/'); define('SITE_ID_CURRENT_SITE', 1); define('BLOG_ID_CURRENT_SITE', 1); And the server block / virtual host is like this: server { ##DM - uncomment following line for domain mapping listen 80 default_server; #server_name example.com *.example.com ; ##DM - uncomment following line for domain mapping #server_name_in_redirect off; access_log /var/log/nginx/example.com.access.log; error_log /var/log/nginx/example.com.error.log; root /usr/share/nginx/html/wptest; index index.html index.htm index.php; if (!-e $request_filename) { rewrite /wp-admin$ $scheme://$host$uri/ permanent; rewrite ^(/[^/]+)?(/wp-.*) $2 last; rewrite ^(/[^/]+)?(/.*\.php) $2 last; } location / { try_files $uri $uri/ /index.php?$args ; } location ~ \.php$ { try_files $uri /index.php; include fastcgi_params; fastcgi_pass unix:/var/run/php5-fpm.sock; } location ~* ^.+\.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|rss|atom|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ { access_log off; log_not_found off; expires max; } location = /robots.txt { access_log off; log_not_found off; } location ~ /\. { deny all; access_log off; log_not_found off; } } And finally here's an error log: 2013/06/29 08:05:37 [error] 4056#0: *52 rewrite or internal redirection cycle while internally redirecting to "/index.php", client: 127.0.0.1, server: example.com, request: "GET /nginx HTTP/1.1", host: "localhost"

  • Is it possible to "stealth" dual boot a machine?

    - by BrianH
    I have a loaner laptop that has MS Windows with locked down permissions. It works okay for what I need to do, but I started wondering if there was a way to install a separate Windows OS on a separate hard drive to do what I want to do on it. Virtual I wish I could use VirtualBox or VMWare, but that is not an option (I even tried VBox portable). External Drive My next trial was see if it was possible to install Windows on an external drive, and then plug that drive in and boot from it whenever I wanted my own OS. After a few Google searches, I see that is not really a possibility. Swap Primary Drive Another option, would be to get a second internal hard drive, take the existing HD out, and install a new Windows OS on the secondary HD. This would mean swapping the internal hard drive each time I want to switch OSs - doable, but not very convenient. Dual Boot The laptop has an expansion slot where a second hard drive can be plugged in quickly. I thought about Dual booting, but I don't want to mess with the MBR on the primary hard drive. When I have to give the laptop back, I don't want a dual-boot screen to popup. Summary Is there a way to have 2 hard-drives on a machine, each with it's own OS, and maybe use BIOS settings to have only 1 hard drive active at a time? That way both hard drives could be physically connected, but only one would actually be active at a time. I basically want a second OS that does not (can not) affect the existing OS in any way, and can be removed at any time without affecting the existing OS. The secondary OS does not need any of the files on the main hard drive - it's basically like having 2 separate computers using the same hard ware... Is this possible, or would it be easier just to go out and buy a different laptop? Thanks in advance! EDIT I just discovered that my BIOS allows me to pick (at startup) which hard drive I want to boot from. I poked around in the BIOS and there is not a place to disable certain devices, like the primary hard drive. My only concern about plugging in a second hard drive and installing Windows to the second hard drive is that it will mess with the primary hard drive, or add a bootloader screen to pick which windows install to use. My thought would be to physically unplug the primary, plug in the secondary and install windows to the secondary. After the install is working properly, I can plug the primary back in and use the BIOS feature to determine which drive to boot to. Is there any way after I have 2 separate installs on 2 separate hard drives that one of the installs could mess with the MBR on the other drive?

  • Unable to telnet out on port 25 on windows server 2008

    - by NickGPS
    Hi All, I just setup a Windows 2008 R2 server and am trying to get a basic mail server up and running so that I can send emails from my applications. I setup a virtual SMTP server in IIS6 and tried doing a local telnet to port 25, which seemed to work fine. There were no errors during this stage and I can see the mail message appear in the Queue folder. The problem is that mail never leaves the Queue folder. I then tried to telnet to a remote mail server on port 25 but couldn't connect:- telnet 209.85.227.27 25 Could not open connection to the host, on port 25: Connection failed) I checked my firewall and there is a default setting to allow all outgoing TCP traffic with no restriction. I even setup a specific rule for outgoing port 25 traffic but to no avail. I then ran a SmtpDiag.exe command .\SmtpDiag.exe [email protected] [email protected] and received the following output Searching for Exchange external DNS settings. Computer name is WIN-SERVERNAME. Failed to connect to the domain controller. Error: 8007054b Checking SOA for gmail.com. Checking external DNS servers. Checking internal DNS servers. SOA serial number match: Passed.

I have removed antivirus to make sure that it wasn't causing the problem. Any ideas would be much appreciated.

  • How to Setup Ubuntu Mail Server with Google Apps?

    - by Apreche
    I have a domain, let's call it foobar.com. All of the MX records for foobar.com point to Google's mail servers because I am using Google Apps for your domain to manage it. It's great because everyone gets all the advantages of GMail, but our e-mail addresses aren't @gmail.com. I also have a server. Primarily, it's a web server, but it also serves other things. One of the things it serves is the web site for foobar.com and also sites for various virtual hosts such as shop.foobar.com and forum.foobar.com. The server is running Ubuntu 8.04, because I like using LTS releases in production. The thing is, there are various applications running on the server that need the ability to send out emails. Various applications, like the cron jobs, send me e-mails in case of errors. Some of the web applications need to send e-mail to users when they forget their passwords, to confirm new registered users, etc. Lastly, it's nice to be able to send e-mail from the command line using the mail command, or mutt. How can I setup the mail on the web server to go through the Google apps mail servers? I don't need the web server to receive mail, though that would be cool. I do need it to be able to send mail as any legitimate address @foobar.com. That way the forum application can send mails with [email protected] in the from field, and the ecommerce application will have [email protected] in the from field. Also, by sending the mail through the Google servers, we can avoid a lot of the problems with the e-mails being blocked by various spam filters on the web. Google's SMTP servers are trusted a lot more than mine would be. I'm pretty good with administering Linux systems, but I am absolutely brain dead when it comes to e-mail. I need step by step directions from beginning to end on how to set this up. I need to know every thing to install, and every single change to the configuration files that is necessary. I have tried following various howtos and guides in the past, but none of them were quite right. Either they didn't work at all, or they offered a configuration that is not what I wanted. Please help. Thanks.

EDIT: I've now moved the db to where it was looking for: C:\Program Files\Microsoft SQL Server\MSSQL\data\ directory. Now if I start the service, it still does not work - i get this error message in the log: Could not find row in sysindexes for database ID 3, object ID 1, index ID 1. Run DBCC CHECKTABLE on sysindexes. Interestingly, i checked the error log - around the time users reported problems, there is this: 2010-01-08 17:11:26.44 spid51 Configuration option 'show advanced options' changed from 0 to 1.

  • Nagios core Event Handler not working

    - by sivashanmugam
    Nagios Event Handler is not triggering when the service is taking more time to response or down. My configuration in below nagios.cfg enable_event_handlers=1 localhost.cfg define service { use generic-service host_name Server service_description test-server servicegroups test-service check_command check-service is_volatile 0 check_period 24x7 max_check_attempts 4 normal_check_interval 2 retry_check_interval 2 contact_groups testcontacts notification_period 24x7 notification_options w,u,c,r notifications_enabled 1 event_handler_enabled 1 event_handler recheck-service } command.cfg define command{ command_name recheck-service command_line /usr/local/nagios/libexec/alert.sh $SERVICESTATE$ $SERVICESTATETYPE$ $SERVICEATTEMPT$ } alert.sh file !/bin/sh set -x case "$1" in OK) # The service just came back up, so don't do anything... ;; WARNING) # We don't really care about warning states, since the service is probably still running... ;; UNKNOWN) # We don't know what might be causing an unknown error, so don't do anything... ;; CRITICAL) Aha!

  • How to Configure Source NAT (Private IP => Public IP Outbound)

    - by DavidScherer
    I'm running VMWare ESXi Free and have Zentyal SBS 3.2 running as a Gateway. I have 5 Public IPS (CIDR/29, let's call them 69.1.1.1 - 69.1.1.5) and currently Zentyal is bound to 69.1.1.1 as the Gateway, with the other 4 Public IPs set as Virtual Interfaces in Zentyal (wan2-wan5) I have machines sitting on the Private Network (10.34.251.x) that, when going Outbound (to Google for instance) should be seen by the Internet as an IP other than the Gateway (69.1.1.1), this is because our machines need to be able to communicate with 3rd party APIs that expect these requests to come from a specific IP. From what I could find, SNAT (Source NAT) in Zentyal is used to achieve this, but I'm not sure how to configure it and cannot find a specific piece of Documentation for it at Zentyal. I've tried setting this up a couple different ways, with no results and at this point I have no idea if I'm going about this completely wrong, or my lack of experience with networking and the associated terminology is preventing me from placing the correct values in the correct fields. I get the following form to set up "SNAT" rules in Zentyal: Perhaps someone can offer some guidance and definitions for the fields above? SNAT Address Is this the Public IP I want to masquerade? Outgoing Interface Should this by my External NIC (one connected to Public 'Net), or is it the "Private" interface? It sounds as though this should be the External interface as I want the traffic from the internal network sent Out over this Interface (using a different IP than normal, anyway) Source Is the the Source on the internal network (one of the private IPs?), a public IP I want to masquerade as, or something else entirely? Destination Is this a place on the Internet (eg, "Only do this for the Site Google.com"/IP) or am I allowing myself to become confused again? Service I'm assuming this allows me to restrict which services this rule will apply to, but is it for a service on the internal network or a service being accessed on the external network? If I can offer any further details or information to make what I'm trying to do more clear, I will happily do so. Honestly any kind of help here would be very appreciated. I'm not a NetOps or anything even close, I spend most of my day writing code and my entire "team" at this company consists of "me, myself, and I" so while I try to broaden my KB at every possible opportunity, I can only learn so much, so fast and I feel like with networking especially there's just so much, coupled with a learning curve for each solution that likes to (from my limited perspective) use slightly different terminology that what I'm used to (and I don't exactly have the necessary experience to cross reference this stuff with the stuff I already know in context).
