• nginx folder redirect

  - by orbalon

  I'm trying redirect from an exact folder in nginx.conf Given the URL: domain.com/path1/path2/path3 Redirect to: sub.domain.com/path1/path2/path3 Here's what I have so far: location ~* ^/path1[\/?]$ { rewrite ^/(.*) http:sub.domain.com/$1 break; } I had it working with location /path1 { rewrite ^/(.*) http:sub.domain.com/$1 break; } The problem with that is it also redirects a page like domain.com/path1moretext/someotherpath to sub.domain.com/path1moretext/someotherpath Which is not what I want. (had to take out the "//" in the href code above because this is my first post, sorry).

• DrayTek Vigor 2920(n): VPN with VLAN restrictions?

  - by Dirk

  Hi, I'm currently installing a DrayTek Vigor 2920n router in a new office. This router is to be used for 2 seperate companies. For one of these companies, the router has a LAN-2-LAN (VPN) connection to a datacenter configured. The other company should not be able to access this other (VPN-)network. I'm aware of the capability of this router to have VLAN's, but I cannot figure out how to configure the VPN-connection to only be accessible for VLAN0 and not for VLAN1. I know I can also add another router to physically split both networks, but we bought the DrayTek with the idea that it could easily have the VPN-connection available for VLAN0 and not for VLAN1. VLAN1 can easily be in another subnet, that's fine, although, I don't know how to configure that on this DrayTek. Can anyone point me in the right direction? Thanks in advance, Dirk

• Ping "replies" from same computer with 'Destination host unreachable' (no route to other computer)

  - by Srekel

  I've got two computers in a LAN behind a wireless router.

• can't get php mail() working on Ubuntu desktop version with sendmail and postfix

  I'm running Ubuntu 9.10 LAMP and trying to do a simple email test with PHP and I'm not getting any emails sent. mail("[email protected]", "eric-linux test", "test") or die("can't send mail"); I get no errors from PHP when running that script.

• Zabbix - Some of the monitored items don't refreh

  - by Niro

  I'm experiencing a strange issue with Zabbix monitoring a MySQL server. Most of the data from the server such as MySQL queries per second and MySQL uptime , Buffers memory etc. update nicely while some data like CPU iowait time (avg1) , Host local time ,MySQL number of threads and other items which were monitored in the past has last check time of about a week ago. I can't find any logic in this, for example Mysql number of threads and Mysql queries per second are obtained in a similar way so it does not make sense one of them is monitored and one is not. Please help- how can I fix this? Update - I used zabbix_get from the zabbix server to check one of the items on the zabbix client and it works so the problem must be on the zabbix server side

• Proper network configuration for a KVM guest to be on the same networks at the host

  - by Steve Madsen

  I am running a Debian Linux server on Lenny. Within it, I am running another Lenny instance using KVM. Both servers are externally available, with public IPs, as well as a second interface with private IPs for the LAN. Everything works fine, except the VM sees all network traffic as originating from the host server. I suspect this might have something to do with the iptables-based firewall I'm running on the host. What I'd like to figure out is: how to I properly configure the host's networking such that all of these requirements are met? Both host and VMs have 2 network interfaces (public and private). Both host and VMs can be independently firewalled. Ideally, VM traffic does not have to traverse the host firewall. VMs see real remote IP addresses, not the host's. Currently, the host's network interfaces are configured as bridges. eth0 and eth1 do not have IP addresses assigned to them, but br0 and br1 do. /etc/network/interfaces on the host: # The primary network interface auto br1 iface br1 inet static address 24.123.138.34 netmask 255.255.255.248 network 24.123.138.32 broadcast 24.123.138.39 gateway 24.123.138.33 bridge_ports eth1 bridge_stp off auto br1:0 iface br1:0 inet static address 24.123.138.36 netmask 255.255.255.248 network 24.123.138.32 broadcast 24.123.138.39 # Internal network auto br0 iface br0 inet static address 192.168.1.1 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 bridge_ports eth0 bridge_stp off This is the libvirt/qemu configuration file for the VM: <domain type='kvm'> <name>apps</name> <uuid>636b6620-0949-bc88-3197-37153b88772e</uuid> <memory>393216</memory> <currentMemory>393216</currentMemory> <vcpu>1</vcpu> <os> <type arch='i686' machine='pc'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='cdrom'> <target dev='hdc' bus='ide'/> <readonly/> </disk> <disk type='file' device='disk'> <source file='/raid/kvm-images/apps.qcow2'/> <target dev='vda' bus='virtio'/> </disk> <interface type='bridge'> <mac address='54:52:00:27:5e:02'/> <source bridge='br0'/> <model type='virtio'/> </interface> <interface type='bridge'> <mac address='54:52:00:40:cc:7f'/> <source bridge='br1'/> <model type='virtio'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> </devices> </domain> Along with the rest of my firewall rules, the firewalling script includes this command to pass packets destined for a KVM guest: # Allow bridged packets to pass (for KVM guests). iptables -A FORWARD -m physdev --physdev-is-bridged -j ACCEPT (Not applicable to this question, but a side-effect of my bridging configuration appears to be that I can't ever shut down cleanly. The kernel eventually tells me "unregister_netdevice: waiting for br1 to become free" and I have to hard reset the system. Maybe a sign I've done something dumb?)

• Caching without file extensions

  - by Sigurs

  I'm trying to use Varnish to show the non-logged in users a cached version of my website. I'm able to perfectly detect if the user is logged in or out, but I can't cache pages without extensions. There is no file extension because nginx is rewriting the URL to a php script(so caching .php does not work). For example I'd like varnish to cache: example.com example.com/forum/ example.com/contact/ I have tried if (req.request == "GET" && req.url ~ "^/") { return(lookup); } if (req.request == "GET" && req.url ~ "") { return(lookup); } if (req.request == "GET" && req.url ~ "/") { return(lookup); } but nothing seems to work... any help?

• Using NDMP as an alternative to CIFS mount

  - by user138922

  I have a weird but interesting use-case. I use CIFS to mount shares from a File Server (NetApp, EMC etc) to an application server (win/linux server where my application runs). My application needs to process each of the file from the shares that I mount via CIFS. My application also needs access to the meta-data of these files such as Name, Size, ACLs etc. I would like to see if I can achieve the same via NDMP. I have some very basic questions regarding this use-case. It would be great if you guys can help me out here. Is this even something which is achievable? Can I just transfer share that interest me instead of entire volume?

• Static file serving only works if root is a subfolder under public

  - by lulalala

  I am trying to serve static cache files using nginx. There are index.html files under the rails_root/public/cache directory. I tried the following configuration first, which doesn't work: root <%= current_path %>/public; # $uri always contains one slash(the first slash but not the last) try_files /cache$uri/index.html /cache$uri.html @rails; This give error: [error] 4056#0: *13503414 directory index of "(...)current/public/" is forbidden, request: "GET / HTTP/1.1" I then tried root <%= current_path %>/public/cache; # $uri always contains one slash(the first slash but not the last) try_files $uri/index.html $uri.html @rails; And to my surprise this works. Why is it that I can do the latter not the former( since they point to the same location) The permissions of the folders are: 775 public 755 cache 644 index.html The thing is that my favicon sitting under public/ is served correctly: # asset server server { listen 80; server_name assets.<%= server_name %>; expires max; add_header Cache-Control public; charset utf-8; root <%= current_path %>/public; }

• /proc/net/dev and /sys/class/net/ bogus network interface names

  - by sfink

  I am constructing a list of network interfaces to monitor based on the contents of /proc/net/dev. But I am getting some bogus interfaces in the list: __tmp1104705027 __tmp974528607 Where do those come from? They also show up in /sys/class/net/: # ls -1 /sys/class/net/ eth0 eth1 eth2 eth3 lo sit0 __tmp1104705027 __tmp974528607 For now, I think I'll just ignore anything starting with __tmp, but I'd like to know what they are and where they come from.

• zero-config CGI enabled web server

  - by halp

  To serve static content of a directory over http, one can simply navigate to that directory and type: python -m SimpleHTTPServer 11111 which will start a http server on port 11111. This hack is nice because it requires zero-config: no stand-alone web server, no config files at all. Is it possible to extend this example, or have an alternate way to achieve this goal, but also have CGI support? The final goal is to have a quick and lazy way of serving a web site from a certain directory. The site has static content (HTML pages, images), but also a CGI script. The CGI script must work properly when accessed via browser. Of course I could setup a virtual host in apache, allow CGI inside it etc. But that's not a zero-config approach.

• Getting around the lack of GPT support with CentOS 5.4

  - by sxanness

  Here is my issue and I hoping that there is someone out there that has an answer so I don't end up stuck here at my co-location all day. Last night I came here and upgraded a server (Dell 2970) to have four 1TB Hard Drives in RAID 5 which leaves a 3TB block. I tried to partition this but keep getting an error that GPT is not supported so I found a site online telling me I need to run the dd command and right random data to /dev/sda. This is great (if it works) but taking forever. I have two more machines to upgrade today and not a chair in site. Does anyone have advice on how I can avoid this issue beforehand? Thank You for your advice and support.

• How can I proxy couchDB as a sub-diectory with lighttpd?

  I have a sub-directory on my web server (lighttpd) that I want to point at a CouchDB instance running on the same machine. I tried using mod_proxy but it sends along the whole request, like a proxy should, I know! So: // What happens: Lighttpd: http://localhost/couchdb/some_request | V CouchDB: http://localhost:5984/couchdb/some_request // What I want to happen: Lighttpd: http://localhost/couchdb/some_request | V CouchDB: http://localhost:5984/some_request Is there any way to make this setup work?

• Upgrade MySQL on Plesk on Windows

  - by Cyril Gupta

  I just got a nasty surprise when I installed a website in Unicode Hindi (Indian language) on a server, all freshly entered unicode data is turning into question marks on the server. On my dev machine it works perfectly. I found that I have MySQL version 5.0.45 (installed in default by Plesk I guess). On my dev machine i have version 5.1.33. I believe the problem could be due to the version difference. The new version of MySQL apparently has better support for Unicode than the older one. I want to upgrade MySQL on my Windows Server machine with Plesk installed on it I am reluctant to just install the new version using the mysql installer because Plesk maintains some custom settings for mysql and I am afraid the new version could change those settings and break my db. Can anyone tell me do I have to do anything special to install MySQL on plesk on windows or can I just use the new version installer?

• Monitoring outgoing bandwidth of application

  I currently have a VPS that is consuming a ton of outgoing bandwidth and I am trying to drill down to where this may be coming from. Does anyone know of a logical way to go about finding out which pages on the site are consuming the most outgoing data. We have done a ton of front-end optimizations to the site and our google page speed rankings ar 85% so I feel we have done a pretty great job at optimizing the site for speed. Can someone lend some insight on how they have made similar optimizations? Application / Server Stack LEMP Running Varnish Cache / PHP5-FPM WordPress running w3 Total Cache Ubuntu 12.04 LTS

• Clients didn't switch to secondary DNS server during fail over

  - by The Digital Ninja

  I have two internal dns servers set up and all my servers have both of them in the resolv.conf Our main dns server went down and suddenly no server could see each other. I edited a few of the servers resolv.conf manually and committed out the first (down) dns server and that machine would instantly be able to ping again. What did I do wrong, does it not auto switch to the secondary dns server when it times out? # File managed by puppet nameserver 192.168.146.100 nameserver 192.168.159.101 ;nameserver 72.14.188.5 domain example.com search example.com

• esxi VM will not connect to virual switch

  - by NitroxDM

  I have a exsi box with a VM (Windows 2003) that will not connect to any of the switches. The switch shows the VM connected but I can not ping anything on the network. I have double checked the VM's IP. No dice. There are a ton of messages in the log: [DATE 'VmMisc' NNNNN warning] Failed to validate VM IP address: unknown Update: There are 3 other VMs. Each vSwitch has 56 ports. I can ping from one nic to the other. Each vSwitch shows that the new VM is connect. VMware ESX Server 3i V 3.5.9 Build 123629 Update 2: Out of the blue it just started working. I didn't change anything. I think it has something to do with RRAS.

• CentOS 5.7 keeps rebooting after fresh installation

  - by Wagner Maestrelli

  I have just installed CentOS 5.7 x86_64 on a new computer. The installation went on without any issues. But, after it finnished, the machine started to show an awkward behaviour: it restarts every time it tries to boot. It happens after all the services have been started. The screen just goes black and it shows an error message from the monitor: Input not supported. And then it reboots. I took a look at the logs, but I couldn't manage to find anything. Any help? Update Before doing the hardware diagnosis, as pointed out, I decided to make some tests. First, I changed the runlevel to 3, adding the 3 parameter at the end of the kernel command. Then, after logging in in text mode, I checked the xorg.conf file out for some problems regarding the screen resolution. There was nothing unexpected set. Well, if there had to be a problem with it, I couldn't start the X server at the command line, right? So, I typed startx and Gnome started! So, probably, it's not an issue with the screen resolution, I suppose. Then I selected the Log Out root... Gnome menu option and something odd happened: the screen went black, the Input not supported monitor error message was displayed and the system rebooted. Yes, the same problem I was having while trying to boot! After that, I decided to try yet another test: I removed the rhgb quiet parameters from the kernel command to see if some error would show up. Well, to my surprise, the boot went on without problems! The Gnome login screen showed up, I logged in and the session started. But then I selected the Shut Down... menu option and guess what? Same problem: black screen, same monitor error and the system rebooted. Yes, it rebooted, it did not shut down. I repeated both of the tests and the behaviours were the same. I really don't know what's going on. It seems to be an issue regarding the changing of the screen mode or something like that. Any ideas? Could this be a hardware problem? Or does it seem to be something regarding the system configuration?

• Allowing connections initiated from outside

  - by Mark S. Rasmussen

  I've got an old Juniper SSG5 running ScreenOS 5.4.0r6.0. Once a day, more or less, it'll start randomly dropping packets at a rate of ~5-10%. We currently solve this issue by simply rebooting the unit, after which it resumes working in perfect condition. As this error has started appearing randomly, without any configuration or hardware changes, I'm assuming I've got an aging unit about to fail. As such, I've got a replacement SSG5 running ScreenOS 6.0. I've dumped the config on the 5.4 and imported it into a clean 6.0, and it seems to gladly accept it, and all my configuration seems to be A-OK. However, upon connecting the new unit, all outside-initiated connections seem to be blocked. If I browse our external IP from the inside, everything works perfectly, and it's not just port 80, SSH, Crashplan - all of our policies route correctly. All normal networking, initiated from the inside, work perfectly as well. If on the other hand I browse our external IP from the outside, everything is blocked. Barring differences between ScreenOS 5.4 and 6.0, the config is identical. Is there a setting somewhere that defines whether outside/inside initiated connections are allowed? unset key protection enable set clock timezone 1 set vrouter trust-vr sharable set vrouter

• Issue with IIS...SERVER APPLICATION UNAVAILABLE

  - by SVI

  My web application was running absolutely fine. Just 2 days back, I got an error saying. SERVER APPLICATION UNAVAILABLE I am pretty certain that nothing was changed on IIS. Unless my automatic Windows updates screwed it up completely. My event viewer had zillions of following errors in Application category. aspnet_wp.exe could not be started. The error code for the failure is C0000005. This error can be caused when the worker process account has insufficient rights to read the .NET Framework files. Please ensure that the .NET Framework is correctly installed and that the ACLs on the installation directory allow access to the configured account. I reinstalled IIS. After installing, i ran aspnet_regiis -i for framework v2 and now it throws error saying - The application could not be initialized properly. Any ideas what going on?
