• Looking for suitable backup solution Mac OS X to offsite Centos 6 server 1TB of working data

  - by Brady

  I'll start by saying what we have in place currently: On site file server (Mac OS X Server) that is used by GFX designers and they have a working 1TB of data. Offsite server with 2TB available storage (Centos 6) Mac OS X server rsync data to offsite server every 6 hours (rsync -avz --delete --progress -e ssh ...) Mac OS X server does full data backup to LTO 4 tape on a 10 day recycle (Mon-Fri for 2 weeks) rsync pushes about 60GB of file changes a day. The problem: The onsite tape backup is failing as 1TB of graphics files don't compress well to fit onto a 800GB LTO4 tape. Backup is incredibly slow doing a full backup. Pain in the backside getting people to remember to change the tape. Often gets forgotten etc The quick solution: Buy LTO5 Drive and tapes. However this has been turned down because of the cost... What I would like: Something that works in the same way rysnc works. Only changed data is sent over the wire and can be scheduled to run multiple times during the day. Data that is sent is compressed and sent over SSH. Something that keeps a 14day retention but doesn't keep duplicate data So as an example if I have 1TB of working data and 60GB of changes are made each day then I expect around 1.84TB of data to be stored on the offsite server. To work with the Mac OS X server and Centos 6 server. Not cost an arm and a leg. Must be a cheaper solution than buying an LTO5 drive with tapes (around £1500). Be able to be setup to run autonomously. Have some sort of control panel that will allow an admin to easily restore a file/folder. Any recommendations?

• Storing changes to multiple databases in a single centralized database

  - by B4x

  The setup: multiple MySQL databases at different locations with the same scheme. The databases are in production. The motivation: we want to present information in these databases in a web interface, clearly showing which database the row originated from. We want to be able to get this data from one single source (for different reasons, one of them is pagination which gets tricky if you use multiple sources). The problem: how do we collect data from multiple databases, storing it at a central location and clearly marking the origin of each row? We have discussed using a centralized DB that tracks changes to the production DBs, with the same schema and one additional column for origin. If possible, we would like to avoid having to make changes in the production environment. Since we can't use MySQL's replication (multiple masters to a single slave isn't allowed), what are our other options? Are there any existing solutions for something like this or do we have to code something ourselves? Is the best solution to change the database schemas in production and add a column for origin? The idea of a centralized database isn't set in stone. If there is a solution to this that solves our other problems without a centralized DB, we can be flexible. Any help is much appreciated.

• Configuring CakePHP on Hostgator

  - by yaeger

  I have absolutely no idea what I am doing wrong here. I have followed just about every guide there is with installing cakephp on shared hosting and I am still having problems. I have also started over each time when following a guide. Maybe someone can help me out here as I am out of options. Here is my current setup: / app webroot vendors lib cake public_html .htaccess index.php plugins I have configured the index.php file in the public_html to point to the correct files. I have also done this in the index.php file located in webroot folder. I am getting an Internal 500 server error and it says to check my logs for what the error specifically is. However there are no logs being generated. I removed the .htaccess file from the public_html folder and I get the following errors: Warning: require(/app/webroot/index.php) [function.require]: failed to open stream: No such file or directory in /home/user/public_html/index.php on line 40 Fatal error: require() [function.require]: Failed opening required '/app/webroot/index.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/user/public_html/index.php on line 40 line 40 is require APP_DIR . DS . WEBROOT_DIR . DS . 'index.php'; DS = "/" WEBROOT_DIR = "app" Anyone have any suggestions? I am at lost at what I am doing wrong.

• Munin graphing by CGI

  - by Vaughn Hawk

  I have Munin working just fine, but any time I try to do cgi graphing - it just stops graphing... no errors in the log, nothing. I've followed the instructions here: http://munin-monitoring.org/wiki/CgiHowto - and it should be working - here's my munin.conf setup, at least the parts that matter: dbdir /var/lib/munin htmldir /var/www/munin logdir /var/log/munin rundir /var/run/munin tmpldir /etc/munin/templates graph_strategy cgi cgiurl /usr/lib/cgi-bin cgiurl_graph /cgi-bin/munin-cgi-graph And then the host info yada yada - graph_strategy cgi and cgrurl are commented out in munin.conf - that's because if I uncomment them, graphing stops working. Again, I get no errors in logs, just blank images where the graphs used to be. Comment out cgi? As soon as munin html runs again, everything is back to normal. I'm running the latest version of munin and munin-node - I've tried fastcgi and regular cgi - permissions for all of the directories involved are munin:www-data - and my httpd.conf file looks like this: ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory /usr/lib/cgi-bin/> AllowOverride None SetHandler fastcgi-script Options ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> <Location /cgi-bin/munin-cgi-graph> SetHandler fastcgi-script </Location> Does anyone have any ideas? Without this working, at least from what I understand, Munin just graphs stuff, even if no one is looking at them - you add 100 servers to graph, and this starts to become a problem. Hope someone has ran into this and can help me out. Thanks!

• Tcpreplaying using VMware

  - by Methos

  This is more like a testbed setup question. I want to use VMware to debug some networking code in the linux kernel in the VM. My VM has two network interfaces. What I want to do is replay the capture file in the host and receive the packets in the VM. My problem is I do not see replayed packets in the VM. I am running VMware and tcpreplay on the host as sudo. Hence I think there should not be any problem access devices files. I am running VMware workstation 7.0 a. I first began with Custom networking as that provides option of creating your own virtual network name. I wrote /dev/vmnet3 and /dev/vmnet4 for the two interfaces respectively. However, after booting the guest, I did not see any of these interfaces or devices files (in /dev) created on the host. b. Then I tried 'Host Only', but that does not show what bridge/device file is associated with the interface. c. Finally I tried bridged networking mode. I see vmnet1, vmnet8 and vboxnet0 on the host. I have tcpreplayed the capture file on each of these interfaces, for all the above three cases. I tried to capture packets in the VM using "tcpdump -i any". However, I do not see any packets. Any ideas/pointers?

• PHP-FPM issue on LEMP Stack and WordPress

  - by jw60660

  I'm very much a NGINX and Server Admin beginner. I used this tutorial to install NGINX / PHP / mySQL / WordPress: C3M Digital Tutorial In this tutorial the backend php-cgi setup is configured using fastcgi. php5-fpm was installed during this tutorial: apt-get install nginx-full php5-fpm php5 php5-mysql php5-apc php5-mysql php5-xsl php5-xmlrpc php5-sqlite php5-snmp php5-curl After reading that the NGINX configuration on the WordPress codec was more secure than most tutorials, I decided to use the codex configuration: WordPress NGINX configuration in Codex The Codex configuration uses php-fpm for backend php-cgi. When opening the browser I got a 502 Bad Gateway error. The error log was: "2012/06/10 21:18:27 [crit] 14009#0: *4 connect() to unix:/tmp/php-fpm.sock failed (2: No such file or directory) while connecting to upstream, client: 12.3.456.789, server: mywebsite.com, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-fpm.sock:", hos t: "mywebsite.com"" In the main NGINX configuration file supplied by the codex I noticed the line starting "server unix:" in the upstream php block which point to the empty directory: # Upstream to abstract backend connection(s) for PHP. upstream php { server unix:/tmp/php-fpm.sock; # server 127.0.0.1:9000; } I checked the folder at /tmp and it was empty. Seems I missed configuring php-fpm to play with NGINX. Can someone point me in the right direction? Much appreciated!

• CentOS centralised logging, syslogd, rsyslog, syslog-ng, logstash sender?

  - by benbradley

  I'm trying to figure out the best way to setup a central place to store and interrogate server logs. syslog, Apache, MySQL etc. I've found a few different options but I'm not sure what would be best. I'm looking for something that is easy to install and keep updated on many virtual machines. I can add it to a VM template going forward but I'd also like it to be easy to install to keep the VM complexity down. The options I've found so far are: syslogd syslog-ng rsyslog syslogd/syslog-ng/rsyslog to logstash/ElasticSearch logstash agent in each log "client" to send to Redis/logstash/ElasticSearch And all sorts of permutations of the above. What's the most resilient and light from the log "client" perspective? I'd like to avoid the situation where log "clients" hang because they are unable to send their logs to the logging server. Also I would still like to keep local logging and the rotation/retention provided by logrotate in place. Any ideas/suggestions or reasons for or against any of the above? Or suggestions of a different structure entirely? Cheers, B

• KVM and JBoss Java Application Server

  - by Jason

  We have a large Xen deployment running on both RHEL and CentOS and have recently started looking at KVM since this is where it looks like the future of VM's are on Linux. We can load the server and get everything running without an issue. However when we load up a new one with JBoss (4.2 Community edition, Sun JDK 6) and load a large EAR the server goes a little crazy. The %sy will jump to 80-99% and just hang for large periods of time we see a similar jump in %us on the host machine. We though at first this might be I/O as it seems to happen at start of JBoss but then would "cool down" after everything got loaded. We did some tests by extracting some large tar.gz files and using jar -xvf on the ear but could not re-create. Then we starting thinking this might be some type of memory access issues. We loaded a c-program that would generate a lot of memory activity and sure enough we saw the spikes again. Not as high mind you but we did see it jump. We then wrote a small java program to do the same thing and sure enough we saw it jump again. Any thoughts on what might be causing this? Is this just the way KVM works? As a side note we do NOT see this behavior on any other setup. Xen, VMWare and/or native iron. The system does seem a bit slower than our Xen / VMware ones.

• ISA 2000 and COD MW2 Steam

  - by twlichty

  OK, so maybe not the "proper use" of network resources, but we enjoy the odd COD game during lunch hours. When we played COD4, we had a dedicated server setup at the back of the server room. With MW2, we need to be able to connect to steam to be able to play multi-player. I've found this support article here: https://support.steampowered.com/kb%5Farticle.php?ref=8571-GLVN-8711 Which outlines all the ports I need to open. I went through and created the following rules in ISA 2000 (I'm stuck with 2000 for now). Protocol Definition: Steam Primary connection: Port 27000, UDP, Send Receive Secondary Connection: Port range 27001-27030 Send Receive Protocol Definition: Steam TCP In Primary connection: 27014, TCP, Inbound Secondary Connection: Port range: 27015-27050, Inbound Protocol Definition: Steam 4380 Primary connection: 4380, UDP, Send Receive When I start steam on my local workstation (I did add an exception to the Vista Firewall to allow steam), the steam client sits on "Updating Steam" for 5 minutes then errors out with: You must connect to the internet first. Any ideas? I assume I missed something. Thanks for your help.

• My Boot order changed. Why?

  - by Chris

  I have a laptop running Windows XP SP3 with one internal hard drive partitioned into C: (system), D: (storage) and I have an external hard drive, F: (external drive). Yesterday the machine was running fine. Today, I go back to it and see that it's just showing a blinking cursor. Checked through the BIOS and the hard drive checked out fine. CTRL-ALT-DELETED the machine a few times, but I was never able to boot back into the operating system. I threw in a live CD and found out that the boot order of the drives has changed. The external drive is now C:, the system partiton is D:, and the storage partition is E:. Does anyone have any idea of how or why this would have occured? Auto system updates are turned off so there should have been no automatic reboot of the system overnight, and anti-virius runs on the machine and has found no infections before this occured. Edit When I was looking through the BIOS of the machine, I did see that the boot order was changed. But still the same question remains, what would have caused this to happen? I can't believe that a random reboot happened and totally changed my hard drive setup.

• Home network with two isolated separate subnets, running on cablemodem/router and WRT-router.

  - by Johan Allgoth

  I have a new connection with a nice new router/cable-modem. I'd like to setup it up optimally and needs some pointers. I am a complete n00b when it comes to routing. I want to end up with two separate subnets, 10.1.2.0/24 and 192.168.1.0/24 each available on their own wireless channel/SSID. Both firewalled. I want my wired computers on the gigabit switch, optimally with public ips. I want to be able to reach 192.168.1.0/24 from 10.1.2.0/24, but not vice versa. Everyone should have internet access. Hardware and capabilities: Netgear CG3100. Handles cable connection. Gigabit switch. 802.11n. Can do DHCP, firewall, NAT etc. Can choose subnet. Can turn of NAT and if so hand out up to 4 public ips. Somewhat challenged when it comes to configuration. WRT-router. Runs DD/Open-WRT very stable. 100 Mbit switch. 802.11.g Can do DHCP, firewall, NAT etc. Can choose subnet. Highly configurable. I hope to be able to keep 10.1.2.0/24 on the CG3100, for speed reasons and 192.168.0.0/24 on the WRT-router for quota and user control reasons. On my 10.1.2.0/24 network I plan on running servers for various services. Should I turn of NAT on the WRT-router? Or on the cable modem? Activate what in that case? Is double NAT always f-ed up?

• Strange behaviour when creating/deleting subdomains

  - by Saif Bechan

  This can be a DNS cache issue from my local machine, but I am not sure. This is what happens. I have a domain that does not use wildcard subdomains, so they have to be created. Without creating the domain, and I point my browser to test.domain.com, I get a page server not found. Now when I create the subdomain, I keep getting the same problem. Now when I first create the domain, without ever visiting the page, I get the normal page, but now when I delete the subdomain, it never goes away. Can this be a DNS cache issue, I am working on a shared environment, maybe the router has a cache but I doubt that. Can this have something to do with my setup. I have tried to use the Google DNS hosting, but this gives me the same results. I have also tried some tools that clear my local DNS cache, they were some add-ons for FireFox. Anyone have any ideas what can be the problem. Are there any tests I can do to see if there is some kind of cache between me and the server.

• Connection refused after installing vsftp on Ubuntu 8.04 with fail2ban

  - by Patrick

  I have been using an Ubuntu 8.04 server with fail2ban for a while now (12+ months) and using ftp over SSH without any problems. I have a new user that needs to put files onto the server from an IP modem. I have installed vsftp (sudo apt-get install vsftp) and everything installed correctly. I have created an ftp user on the server following this guide. Whenever I try to connect to the server with my ftp program (filezilla) I get an immediate response of: Connection attempt failed with "ECONNREFUSED - Connection refused by server". I have looked into fail2ban and cannot find any problems.

• Hotmail marking messages as junk

  - by Canadaka

  I was having problems with emails sent from my server being blocked completely by Hotmail, but I found out Hotmail had blocked my IP and by contacting Hotmail I had the block removed. See this question for more info: Email sent from server with rDNS & SPF being blocked by Hotmail But now all emails from my server are going directly to recipients "Junk" folder on hotmail and I can't figure out why. Hotmail says "Microsoft SmartScreen marked this message as junk and we'll delete it after ten days." I tried contacting the same people at Hotmail who had my IP block removed, but I haven't received any reply and its been almost a week. Here are some details: I have a valid SPF record for my domain "v=spf1 a include:_spf.google.com ~all" I have reverse DNS setup I have a Sender Score of 100 https://www.senderscore.org/lookup.php?lookup=66.199.162.177&ipLookup.x=55&ipLookup.y=14 I have signed up for Microsoft's SNDS and was approved.

• Turn off monitor (energy saving) while in text console mode (in Linux)

  - by Denilson Sá

  How to configure Linux text console to automatically turn of the monitor after some time? And by "text console" I mean that thing that you get on ctrl+alt+F[1-6], which is what you get whenever X11 is not running. And, no, I'm not using any framebuffer console (it's a plain, good and old 80x25 text-mode). Many years ago, I was using Slackware Linux, and it used to boot up in text-mode. Then you would manually run startx after the login. Anyway, the main login "screen" was the plain text-mode console, and I remember that the monitor used to turn off (energy saving mode, indicated by a blinking LED) after some time. Now I'm using Gentoo, and I have a similar setup. The machine boots up in text-mode, and only rarely I need to run startx. I say this because this is mostly my personal Linux server, and there is no need to keep X11 running all the time. (which means: I don't want to use GDM/KDM or any other graphical login screen) But now, in this Gentoo text-mode console, the screen goes black after a while, but the monitor does not enter any energy-saving mode (the LED is always lit). Yes, I've waited long enough to verify this. Thus, my question is: how can I configure my current system to behave like the old one? In other words, how to make the text console trigger energy-saving mode of the monitor? (maybe I should (cross-)post this question to http://unix.stackexchange.com/ )

• Tips and Suggestions IP Address Re-Addressing?

  - by RSXAdmin

  Hello serverfault Universe, My ever evolving and expanding local area network is currently using a class-C address. My network consists of multiple subnets depending on site/location. 192.168.1.x is site HQ 192.168.5.x is secondary site 192.168.10.x is so on and so forth. Long story short - I have inherited this network design from the previous admin who has left the company which started off with a dozen people and now has just over 300 full time/part time employees. We do not yet have client VPN access; but we do have site to site VPN setup. My question is, in preparation for outside client access to my network via Cisco ASA, I would like to re-address the HQ site because I understand a 192.168.1.x or 192.168.0.x are not very good choices for a company subnet - it may conflict with a home user's LAN when connecting to my LAN, I believe? Through your experience, does anyone out there have any suggestions and tips on how I can proceed with re-addressing my subnets. If I designed this network I would have gone with a 10.0.0.0 (mask 255.255.255.0) so I am leaning towards changing it to fit. Thank you.

• Can Subject Alternative Name accommodate multiple virtual mail domains?

  - by Lawrence

  I am currently running a postfix server with self signed certificates serving one mail domain, mycompany.com, the mail server is mail.mycompany.com and so is the CN of the certificate. Now, I need to add a new domain to it. The new domain name is mycompany.net to the same server. Since the users already have the root of the old certificate, I'd like to reuse that. However, I'd like to issue a new certificate so users using the SMTP from Outlook/Thunderbird of mail.mycompany.net do not get warnings. If I understand correctly, if I issue a new certificate with CN=mail.mycompany.com and a subjectAltName=DNS:mail.mydomain.net and have postfix serve this, the client will not complain either way about the cn not matching the target host name. Am I correct in this assumption or am I misunderstanding the concept of Subject Alternative Name? Just to avoid conversation, I do not want to have users on mycompany.net addresses use the mycompany.com server because I might (not a technical issue) have to split up into two different locations, and I want to produce an easily migrateable setup.

• NAT confusion regarding cisco ASA5510

  - by LonelyLonelyNetworkN00b

  I'm setting up my first cisco firewalls. A little information first:I have two asa5510 setup in a working active/standby pair. From my ISP i have two public subnets. A /29 and a /26. On my DMZ interface i have the /26 configured. On my WAN Interface i have configured the /29 IPs. My isp routes the /26 via the /29 primary IP. I'm running ASA 8.2. I've turned NAT-Control off, because i don't want to use nat for for other than some internal interfaces. In essence i don't want to use NAT unless i specify it. I have a internal interface with the network of 192.168.100.0/24. I've tried setting up nat limke this: nat (inside) 1 192.168.100.0 255.255.255.0 global (WAN) 1 interface I was under the impression that this would let connections that was going from 192.168.100.0/24 and out the WAN interface to be Port-Address-translated. I'm not getting this to work for some reason. Inside interface has security level of 100, and wan has security level of 0.

• Joomla SMTP Configuration Issue

• HAProxy is caching the forwarding?

  - by shadow_of__soul

  i'm trying to set up a server structure for an application i'm building in Node.js with socket.io. My setup is: HAProxy frontend forward to -> apache2 as default backend (or nginx, is apache in this local test) -> node.js app if the url has socket.io in the request AND a domain name i have something like: global log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 4096 user haproxy group haproxy daemon defaults log global mode http maxconn 2000 contimeout 5000 clitimeout 50000 srvtimeout 50000 frontend all 0.0.0.0:80 timeout client 5000 default_backend www_backend acl is_soio url_dom(host) -i socket.io #if the request contains socket.io acl is_chat hdr_dom(host) -i chaturl #if the request comes from chaturl.com use_backend chat_backend if is_chat is_soio backend www_backend balance roundrobin option forwardfor # This sets X-Forwarded-For timeout server 5000 timeout connect 4000 server server1 localhost:6060 weight 1 maxconn 1024 check #forwards to apache2 backend chat_backend balance roundrobin option forwardfor # This sets X-Forwarded-For timeout queue 50000 timeout server 50000 timeout connect 50000 server server1 localhost:5558 weight 1 maxconn 1024 check #forward to node.js app The problem comes when i made a request to something like www.chaturl.com/index.html it load perfectly but fails to loads the socket.io files (www.chaturl.com/socket.io/socket.io.js) why it redirect to apache (and should redirect to the node.js app that serve the files). The weird thing is that if i access directly to the socket.io file, after refreshing a few times, it loads, so i suppose is "caching" the forwarding for the client when it makes the first request and reach the apache server. Any suggestion of how this can be solved? or what i can try or look about this?

• Sending Mail from Web App to Google Apps won't work - internal routing? VPS

  - by Charlino

  I've got a web application, www.mysuperwebapp.com, which sends out emails for various reasons - the contact us page is a good example. I am using google apps on the domain and I've setup a google apps group, Support ([email protected]), which I want the emails from the contact us page to go to. But the emails don't seem to be sending... I thought it could be that the groups security is a little tighter than normal email, so I change the contact us email to go to [email protected] - but they still didn't appear. So I'm guessing that it has something to do with internal routing and the messages aren't leaving the server/network at all. Eg Sending an email from the mysuperwebapp.com computer to a mysuperwebapp.com email address. I put an entry into the hosts file for 123.123.123.123 mysuperwebapp.com but that doesn't seem to have helped. Also, there doesn't seem to be anything of interest in the event log. What do I need to do? Or what do I need to get my VPS hoster to do? TIA, Charles Ps. The VPS is a Windows 2008 box with IIS7 and the default SMTP (IIS6?) server. The web app is ASP.NET MVC - not that that should matter.

• Inconsistent SMTP Access

  - by Mike Hanson

  I have a mail server setup on Windows Server 2008. All was working fine, until I wanted to map a drive on the server so that I can access files on another machine. Windows prompted me to configure Network Discovery, which I did with the "Home/Office" option rather than "Public". After that, several access points that worked before stopped working, like VNC, SMTP, etc. After reinstalling those packages, things appeared to be working again. Unfortunately, problems have returned with my SMTP server. I can use an web-based SMTP tester, and it connects in 62msec (as expected). However, if I telnet from my machine on the same LAN, it takes more than 20 seconds to connect! When I try to send messages from Outlook, it times out entirely with the message: Sending' reported error (0x80042109) : 'Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).' I've checked the firewall settings, I've tried configuring it to use port 587 instead of 25, but nothing gets around this problem. Does any have any useful insights? Thanks in advance!
