  • apt-get update mdadm scary warnings

    - by user568829
    Just ran an apt-get update on one of my dedicated servers to be left with a relatively scary warning: Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-2.6.26-2-686-bigmem W: mdadm: the array /dev/md/1 with UUID c622dd79:496607cf:c230666b:5103eba0 W: mdadm: is currently active, but it is not listed in mdadm.conf. if W: mdadm: it is needed for boot, then YOUR SYSTEM IS NOW UNBOOTABLE!

  • Connecting to VPN via Proxy

    - by Rodrigo
    Hi, My company's VPN server is located in Netherlands, from my current location this is a really crappy place in terms of connectivity, connection keeps dropping, it's slow and keeps being reset during high traffic times. I have a dedicated server over USA which is able to connect to VPN server without this issues, connection is stable and fast. My question is, how do I connect to this VPN using a proxy running on my dedicated server? I'm on Windows 7 using a VM on XP to connect to the VPN. Thanks.

  • Domain transfer from Yahoo to Godaddy. Google apps downtime

    - by Kedar
    I am moving my domain from Yahoo to Godaddy (cause yahoo charges ridiculously hugh amounts than others). My problem is I use this domain for Google apps and one of those is my custom email. So here are a few questions that I have - 1) Godaddy told me there is going to be a 48 hours of downtime. Is there anything that I can do to minimize the downtime? 2) Will I lose all the email that I get during this downtime? or they be stored in the cloud and bulk emailed me once my domain is up with Godaddy? If they are lost is there any workaround to forward them to my gmail during the downtime (i know sounds stupid, but I have to ask). Any help is much appreciated. Thanks in advance.

  • Sql Server 2005 cluster - unable to rename to old server name

    - by Paul2020
    We have a sql 2005 cluster on W2K8 cluster. It is a named instance say SRV1\A. Then I built a new W2K8 (with a diff cluster service name) but the same service account. Then I installed a new sql 2005 cluster say SRV2\A. Now when I bring down the sql server resources on SRV1 and try to rename SRV2\A to SRV1\A through the cluster admin, I get the error the network name already exists. I have tried bringing an old cluster and installing a new cluster with the same name and it works. Why am I not able to rename the name? Any advice would very helpful.

  • apache+mod_wsgi configuration for django project(s) on a quad core

    - by Stefano
    I've been experiment quite some time with a "typical" django setting upon nginx+apache2+mod_wsgi+memcached(+postgresql) (reading the doc and some questions on SO and SF, see comments) Since I'm still unsatisfied with the behavior (definitely because of some bad misconfiguration on my part) I would like to know what a good configuration would look like with these hypotesis: Quad-Core Xeon 2.8GHz 8 gigs memory several django projects (anything special related to this?) These are excerpts form my current confs: apache2 SetEnv VHOST null #WSGIPythonOptimize 2 <VirtualHost *:8082> ServerName subdomain.domain.com ServerAlias www.domain.com SetEnv VHOST subdomain.domain AddDefaultCharset UTF-8 ServerSignature Off LogFormat "%{X-Real-IP}i %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" custom ErrorLog /home/project1/var/logs/apache_error.log CustomLog /home/project1/var/logs/apache_access.log custom AllowEncodedSlashes On WSGIDaemonProcess subdomain.domain user=www-data group=www-data threads=25 WSGIScriptAlias / /home/project1/project/wsgi.py WSGIProcessGroup %{ENV:VHOST} </VirtualHost> wsgi.py import os import sys # setting all the right paths.... _realpath = os.path.realpath(os.path.dirname(__file__)) _public_html = os.path.normpath(os.path.join(_realpath, '../')) sys.path.append(_realpath) sys.path.append(os.path.normpath(os.path.join(_realpath, 'apps'))) sys.path.append(os.path.normpath(_public_html)) sys.path.append(os.path.normpath(os.path.join(_public_html, 'libs'))) sys.path.append(os.path.normpath(os.path.join(_public_html, 'django'))) os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' import django.core.handlers.wsgi _application = django.core.handlers.wsgi.WSGIHandler() def application(environ, start_response): """ Launches django passing over some environment (domain name) settings """ application_group = environ['mod_wsgi.application_group'] """ wsgi application group is required. It's also used to generate the HOST.DOMAIN.TLD:PORT parameters to pass over """ assert application_group fields = application_group.replace('|', '').split(':') server_name = fields[0] os.environ['WSGI_APPLICATION_GROUP'] = application_group os.environ['WSGI_SERVER_NAME'] = server_name if len(fields) > 1 : os.environ['WSGI_PORT'] = fields[1] splitted = server_name.rsplit('.', 2) assert splitted >= 2 splited.reverse() if len(splitted) > 0 : os.environ['WSGI_TLD'] = splitted[0] if len(splitted) > 1 : os.environ['WSGI_DOMAIN'] = splitted[1] if len(splitted) > 2 : os.environ['WSGI_HOST'] = splitted[2] return _application(environ, start_response)` folder structure in case it matters (slightly shortened actually) /home/www-data/projectN/var/logs /project (contains manage.py, wsgi.py, settings.py) /project/apps (all the project ups are here) /django /libs Please forgive me in advance if I overlooked something obvious. My main question is about the apache2 wsgi settings. Are those fine? Is 25 threads an /ok/ number with a quad core for one only django project? Is it still ok with several django projects on different virtual hosts? Should I specify 'process'? Any other directive which I should add? Is there anything really bad in the wsgi.py file? I've been reading about potential issues with the standard wsgi.py file, should I switch to that? Or.. should this conf just be running fine, and I should look for issues somewhere else? So, what do I mean by "unsatisfied": well, I often get quite high CPU WAIT; but what is worse, is that relatively often apache2 gets stuck. It just does not answer anymore, and has to be restarted. I have setup a monit to take care of that, but it ain't a real solution. I have been wondering if it's an issue with the database access (postgresql) under heavy load, but even if it was, why would the apache2 processes get stuck? Beside these two issues, performance is overall great. I even tried New Relic and got very good average results.

  • WinXP How to Tunnel LPT over USB

    - by Michael Pruitt
    I have a windows program that accesses a device connected to a LPT (1-3) 25 pin port. The communication is bidirectional, and I suspected the control lines are also accessed directly. I would like to migrate the device to a machine that does not have a LPT port. I saw the dos2usb software, but that takes the output (from a DOS program) and 'prints' it formatted for a specific printer. I need a raw LPT connection, and a cable that provides access to all the control signals. I do have a USB to 36-pin Centronics that may have the extra signals. I use it with a vinyl cutter that doesn't like most of the USB dongles. It comes up as USB001. Would adding and sharing a generic printer, then mapping LPT1 to the share get me closer? Would that work for a parallel port scanner? My preferred solution is a USB cable with a driver that will map it to LPT1, LPT2, or LPT3.

  • Remote Sending of Emails via SMTP/EXIM Issue

    - by Christian Noel
    I have been encountering a problem when sending messages via EXIM. Here is the scenario: I have 2 servers lets just say host1.com = where all my apps and programs are hosted. host2.com = is another server which handles some apps but is also my smtp mail server. whm and cpanel are installed in both hosts as well as exim. right now, messages are being sent out as [email protected] to clients. host1.com uses the [email protected] so that it can send messages outbound as well. here's the problem, after a few hours from a fresh reboot of host1.com, sending messages from host1.com is no longer possible because i encounter an error that states: system/vendor/swift/Swift/Connection/SMTP.php [309]: The SMTP connection failed to start [tls://mail.host2.com]: fsockopen returned Error Number 110 and Error String 'Connection timed out'` also note that this was working fine earlier (like 10 hours ago) but then it suddenly fails. everytime i restart the host1.com then sending messages will work again. i have checked logs and traces but to no avail the only means of fixing this problem is restarting host1.com.

  • Strange behavior of logRotate?

    - by superdario
    Hello, I have the following configuration of logrotate: /var/log/test/app.log { missingok notifempty compress copytruncate daily rotate 4 } The application generating the log is a Java application. 2 I set up this configuration yesterday before midnight. Today in the morning I noticed that logRotate made a file called "app.log.1", which only had log entries between 8:21 AM and 10:05 AM. app.log was logging since 10:05 AM. All the logs before 8:21 AM were missing! Furthermore, "app.log.1" wasn't even compressed. Do you know what could've caused this?

  • plesk 9 spamassassin server wide blacklist via cron?

    - by Kqk
    we're running ubuntu 8.04 LTS and plesk 9.2 our simple task is to set up a periodic black list for spamassassin, e.g. using this script .. #!/bin/sh #! Script by AJR to update local spamassassin rules cd /tmp wget -c http://www.stearns.org/sa-blacklist/sa-blacklist.current mv sa-blacklist.current local.cf -f mv local.cf /etc/mail/spamassassin -f rm local.cf -f /etc/init.d/psa-spamassassin restart now, this script runs fine, but plesk doesn't seem to recognize the blacklist in its GUI. which is annoying, especially because plesk itself writes to /etc/mail/spamassassin/local.cf. i wasn't able to find out the secret place, where plesk distinguishes between entries in local.cf added via GUI and command line. any help is appreciated! thanks.

  • mod_security2 and w00tw00t attacks

  • HAproxy - Redirect issue - Uri Variables ?

    - by Justin
    I'm using haproxy 1.5dev3 and I was wondering if there is any possible way to grab uri variables from a request to reappend the query on the end of a redirect url? What I'm trying to do is redirect from: http://www.domain.com/page/example.htm?id=1234567 to: http://www.domain.com/frame/newpage.cfm?id=1234567 redirect prefix doesn't work properly as it tries to append /page/example.htm to the end of the redirect url. Can I do some sort of rewrite to accomplish this? It would be awesome if you could use uri and queries as variables for redirection/pool selection like on F5. Please help...Thanks!

  • Blocking RDP connections from secondary IP addresses

    - by user73995
    Hi, I have a webserver running Windows 2008 R2 with multiple IPs assigned to it. I want to be able to RDP to the box via the main IP assigned to the box but not from any of the secondary IPs (ie... the websites IPs). I assume if I had control of the Firewall I could shut off the RDP port to the secondary IPs but it's in a hosted environment and I don't have access to the firewall. I'll contact the host to see if that's available but was hoping there was a setting I could set on the machine itself to not resolve RDP requests from the additional IPs. Any advice?

  • Multi-Role Domain Controllers for Small Offices (< 50 clients)

    - by kce
    Warning: I'm a Linux/*NIX admin so this is all new to me. I understand that it's not considered a good idea to have only a single domain controller, and that it is also probably a good idea for a domain controller to only do AD/DHCP/DNS (Here). We have two offices, location A with 30 users and location B with 10 users. Our two offices are separated by a WAN that is not particularly robust so I have be instructed that we need to have standalone services in each office. This means that according to "best practices" we will need to build a domain controller and a separate file server in each office. Again, I am not knowledgeable in the ways of Windows but this seems a little unnecessary for an organization of 40 users. People have commented that I could "get away with" running file services on the domain controller as long as the "load is light". That just seems to generate more questions than it answers. What constitutes light load? What are the potential consequences of mixing these roles? Ideally I would prefer to only have one physical machine at each location. The one in location A (the location with IT staff) can act as the primary domain controller and the one in the smaller office can act as the backup domain controller. If either domain controller fails we can still use the other one for authentication (albeit with some latency) and if the WAN connection fails each office still has access to their respective "local" domain controller. If the file services are ALSO run on each server (and synchronized with something like DFS), a similar arrangement in terms of redundancy can be had without having to purchase, build and install two additional separate servers. It's not that I'm adverse to that (well, any more adverse than I am to whole thing to begin with) but to my simple mind it just seems, well a bit overkill. I can definitely see the benefits of functional separation when we're talking larger organizations, but I need to consider the additional overhead too. None of this excludes having a DRP setup for the domain controller/s. I assume you can lose two domain controllers just as easily as one.

  • vmware server end of life, where to go now?

    - by matnagel
    We have some virtual machines on vmware server 2.x running on 64 bit hardware and quite happy with it. As vmware server will no longer be offered we are thinking to migrate to ESXi, which seems is free. We will have to install the specialized network cards but that's a minor problem. But once left alone with a quite silently discontinued product there is some resistance to vmware. VirtualBox seems to work: http://blogs.oracle.com/virtualization/2010/06/migrating_from_vmware_to_virtu.html What other free (of licencing cost) options are there? We have windows server 2003 32 bit VMs and also linux 32 and 64 bit VMs to migrate. So xen does not seem an option, which does not run microsoft OSes.

  • Django Dying on Shared Hosting Environment (Too Many MySQL Connections)

    - by Tom
    I've had a Django site up and running on HostGator (client requirement), following these instructions, for a few weeks now. I had seen two error emails about pages dying with (1040: Too many MySQL connections) but had never been able to recreate the problem. As of today, the site is completely unresponsive and all pages, even the static files, are dying with that error. Two questions: What can I do to fix this (other than caching more stuff)? Why would static files be dying like that? I can request them directly without a problem, so how are they getting run through Django? The shared hosting setup doesn't allow for a <Location> block, but there's a flag in the rewrite rule that says only requests for files that don't exist in the filesystem should be processed. All of my static files exist on the system, though they are symbolically linked files if it matters.

    Recently i setup a Ubuntu 12.04 VPS with 512mb/1ghz CPU, Nginx + php-fpm + Varnish + APC + Percona's MySQL server + CloudFlare Pro for our Ubuntu LoCo Team's WordPress blog. The blog get about 3~4k daily hits, use about 180MB and 8~20% CPU. Everything seems to be working insanely fast... page load is really good and is about 16x faster than any of our competitors... but there is one problem. When we upload a image, WordPress don't resize it, so all we can do it insert the full image in the post. If the imagem have, let's say, 30kb, it resize fine... but if the image have 100kb+, it won't... In nginx error logs i see this: upstream timed out (110: Connection timed out) while reading response header from upstream, client: 150.162.216.64, server: www.ubuntubrsc.com, request: "POST /wp-admin/async-upload.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "www.ubuntubrsc.com", referrer: "http://www.ubuntubrsc.com/wp-admin/media-upload.php?post_id=2668&" It seems to be related with the issue, but i dunno. When that timeout happens, i started to get it when i'm trying to view a post too: upstream timed out (110: Connection timed out) while reading response header from upstream, client: 150.162.216.64, server: www.ubuntubrsc.com, request: "GET /tutoriais-gimp-6-adicionando-aplicando-novos-pinceis.html HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "www.ubuntubrsc.com", referrer: "http://www.ubuntubrsc.com/" And only a restart of php5-fpm fix it. I tryed increasing some timeouts and stuffs but it did not worked, so i guess it's some kind of limitation i did not figured yet. Could someone help me with it, please? /etc/nginx/nginx.conf: user www-data; worker_processes 1; pid /var/run/nginx.pid; events { worker_connections 1024; use epoll; multi_accept on; } http { ## # Basic Settings ## sendfile on;

So... could anyone help me with those issuees, please? Ooohh... if it helps, i instaled PHP like this: sudo apt-get install php5-fpm php5-suhosin php-apc php5-gd php5-imagick php5-curl And Nginx from the official PPA. Sorry for my bad english and thanks for your time people! (:

  • Magento - Users unable to login from corporate networks with Bluecoat / F5 Load balancers

    - by user1330440
    Hoping someone has come across this issue before with Magento and corporate clients. We have two clients for our Magento site who both have their internal networks setup using bluecoat security devices and F5 load balancers. Some users within these networks are unable to login to Magento - Magento eventually is sending a 302 redirect to /index.php/ when users attempt to log in. Through our testing, the problem appears to be isolated to this setup - we can log into the accounts in question from anywhere outside of these networks without issue, and if the client tries to access the site without going through the F5 load balancer, they are able to log in successfully. Strangely enough, the issue only started occurring for the two sites the day after we introduced a system upgrade which added a new site to the Magento installation. The system upgrade should not have affected any standard login functionality, and as said, the problem does not appear to be with the users in question, but with where the users are accessing the site from. Initially we thought the issue might have something to do with communications between the client's networks and the network which the server was hosted on, so we've tried moving the server to different hosts, but this has not helped. I'm currently waiting for more info from the clients on exact devices / models used in their network setup. I will update this post if more information becomes avaliable. Magento version is enterprise edition of ver. 1.9.0.0 Does anyone know of any tucked away Magento settings that might be able to cause this kind of behavior? Experience with this kind of set-up and ideas for things to look at? All help and ideas for things to follow-up would be appreciated - as this is a current production issue for a large number of users. I will respond asap with any requests for additional information on the topic, but currently am not able to disclose any identifying information on the project in question, and/or the clients experiencing issues. Thanks in advance for any assistance offered :) Note: This question has also been posted on the Magento forums: http://www.magentocommerce.com/boards/viewthread/277917/ And also on Stack overflow (Moved here as a commenter thought this site may be better suited): http://stackoverflow.com/questions/10133978/magento-users-unable-to-login-from-corporate-networks-with-bluecoat-f5-load

  • Debian Squeeze Upgrade Breaks Apache SSL

    - by PP
    I upgraded my Debian from Lenny to Squeeze. BIG MISTAKE. Now I get: [Tue Feb 08 16:34:57 2011] [error] Server should be SSL-aware but has no certificate configured [Hint: SSLCertificateFile] ((null):0) littered throughout /var/log/apache2/error.log. How to fix? Looking through a mess of forums it is easy to see that Apache changed the way it reads configurations around 2.2.13. Great. But not great for me or the millions of other web administrators who now have web servers that simply won't start, and an error message that says NOTHING about the problem or how to fix. Anybody else actually solved this issue? I had perfectly working virtual servers with SSL before (for years actually).

  • Setting up a fileserver, some questions?

    - by Tanax
    Recently I've become very interested in setting up a fileserver, mostly for home usage but also because of the fact that I live in 2 places, I need to be able to access my files from both homes. I have already done some research into this but I am unclear about some things. My requirements are the following; Needs to work on both Mac and PC(only using Windows atm on PC but could be good if it supports more OS's to make it futureproof in case I need Linux or something else) Need to be able to set up a folder/drive/network space to act as a link to a certain folder on the fileserver All files should only be stored on the fileserver, e.g. no "shared" folders like in Dropbox where files are stored on the client computer Would prefer it if folders are password protected or that I can somehow specify what users can access the fileserver's shares Fileserver's OS most likely have to be Windows due to other factors outside of being just a fileserver I've already kinda figured out that I will need to set up a VPN so that I can access my fileserver from outside the local network. Probably going to use OpenVPN. Question 1: How would I go about to set up a VPN server so that I can connect to my local network at the fileserver's location? I know that since I'm on a dynamic IP I will have to get some sort of dynamic DNS server - I've already checked into this and I'm fairly sure I know how to fix that. I also know that I will have to forward the port OpenVPN uses in my router. Question 2: How would I actually share the folders on the fileserver so that I can access them on my other computers? I've researched into Samba but I'm uncertain if it needs to be run on a Linux OS. I know that the clients connecting to it can be Windows for example but can the Samba "server" be run on Windows? Also it appears that Samba shares a folder, meaning it works like Dropbox - I don't want that. So how would I share a folder in that case to make it work like I want it to? Sorry for the incredibly long question, I tried to structure it the best I could for easier read. Thanks in advance!
