  • Is there any way to make cherokee server portable?

    - by Tom
    I develop on different machines. I use MAMP, I have it installed on my dropbox folder and created symbolic links to the applications folder. That way if I work one day on my desktop and make changes to let's say a database schema and next day I work from my laptop I won't have to do any db migration stuff the same applies for all the apache virtual hosts I have setup using MAMP. Everything is portable. I recently started using Cherokee server and I like it a lot. I would like to replace MAMP with Cherokee but first I need to be able to make it portable. I don't want to have to configure multiple virtual hosts, settings, etc., on multiple machines. Is there any way I can set up Cherokee to be as portable as MAMP? What if I want to run Cherokee from a thumbdrive?

  • Are there any open source reseller packages?

    - by Tom Wright
    My department has just been given the right/responsibility to manage our own VPS. The idea being that the bureaucracy will be less for the many small web projects we run. Since each project will be managed by a different team, I was planning on approaching a shared hosting model. Are there any free pieces of software that would help automate the provision of resources each time a team request a new project? Most of the projects have identical requirements - basically LAMP - so it would be these resources that I would want provisioning (and de-provisioning, if that is a word) automatically. Ideally, there would also be a way to hook it into our LDAP authentication backend too, though I could probably make this sort of modification if necessary. Since we won't be charging our "client" however, we won't need the ability to generate invoices, handle payments, etc. etc. EDIT: Sample workflow Login authenticated against LDAP Username checked against admin group (not on central LDAP) Click 'new project' and enter project name User created on VPS with project name as username Apache virtual host created and subdomain (using project name) allocated FTP & MySQL users created

  • How do I create an ISO image from a directory structure on CentOS?

    - by tom smith
    I'm trying to figure out the exact mkisofs cmd to create the ISO with the following directory and file structure. I've tried different commands, but when I mount the ISO that is created the directory tree has not been reproduced. The initial directory tree is: master.iso:: mount -o loop /apps/vmware/master.iso /mnt/vmtest ls /mnt/vmtest isolinux ks.cfg upgra32 upgra64 upgrade.sh ls /mnt/vmtest/isolinux boot.cat initrd.img isolinux.bin isolinux.cfg vmlinuz I've used different variations of the following mkisofs command without success: mkisofs -o '/foo/test.iso' -b 'isolinux.bin' -c 'boot.cat' -no-emul-boot -boot-load-size 4 -boot-info-table 'isolinux' How do I make an ISO that captures a directory's exact structure?

  • How to fix semaphore timeout period has expired.

    - by Ryan
    I bough a new hard drive and I'm attempting to copy stuff off the old hard drive to the new one. I tried it using Windows Vista and Windows 7 but no go. Then I tried installing some 3rd party updated drivers that were supposed to fix the problem now my Windows Vista disk won't boot. Has anyone had this problem before and how did you fix it?

  • Change Directory Browsing Page in IIS 7.5

    - by Gabriel Ryan Nahmias
    NOTE: This post is tagged ASP Classic but really that's just one of the languages in which I could write it. I really need assistance with configuring IIS (7.5). I have found many scripts and ideas to effect this but I require that it's not be a "drop-in" replacement, as in it must work globally for any possibly directory from one codebase. Here are several links related to this goal: http://mvolo.com/get-nice-looking-directory-listings-for-your-iis-website-with-directorylistingmodule: Best example of what I want and the one with which I can't seem to follow through. http://www.daleanderson.ca/edb/: This is an example of a "drop-in" replacement (at least it's oriented for that purpose). It still has viable code that could be useful to serve as the main file that processes directory traversal.

  • Multi-WAN bonding across different media

    - by Tom O'Connor
    I've recently been thinking again about a product that Viprinet provide, basically they've got a pair of routers, one that lives in a datacentre, Their VPN Multichannel Hub and the on-site hardware, their VPN multichannel routers They've also got a bunch of interface cards (like HWICs) for 3G, UMTS, Ethernet, ADSL and ISDN adapters. Their main spiel seems to be bonding across different media. It's something that I'd really like to use for a couple of projects, but their pricing is really quite extreme, the hub is about 1-2k, the routers are 2-6k, and the interface modules are 200-600 each. So, what I'd like to know is, is it possible with a couple of stock Cisco routers, 28xx or 18xx series, to do something similar, and basically connect a bunch of different WAN ports, but have it all presented neatly as one channel back to the internet, with seamless (or nearly) failover if one of the WAN interfaces should fail. Basically, If i got 3x 3G to ethernet modems, and each on a different network, I'd like to be able to loadbalance/bond across all of them, without having to pay Viprinet for the privilege. Does anyone know how I'd go about configuring something for myself, based around standard protocols (or vendor specific ones), but without actually having to buy the Viprinet hardware?

  • Can a pool of memcache daemons be used to share sessions more efficiently?

    - by Tom
    We are moving from a 1 webserver setup to a two webserver setup and I need to start sharing PHP sessions between the two load balanced machines. We already have memcached installed (and started) and so I was pleasantly surprized that I could accomplish sharing sessions between the new servers by changing only 3 lines in the php.ini file (the session.save_handler and session.save_path): I replaced: session.save_handler = files with: session.save_handler = memcache Then on the master webserver I set the session.save_path to point to localhost: session.save_path="tcp://localhost:11211" and on the slave webserver I set the session.save_path to point to the master: session.save_path="tcp://192.168.0.1:11211" Job done, I tested it and it works. But... Obviously using memcache means the sessions are in RAM and will be lost if a machine is rebooted or the memcache daemon crashes - I'm a little concerned by this but I am a bit more worried about the network traffic between the two webservers (especially as we scale up) because whenever someone is load balanced to the slave webserver their sessions will be fetched across the network from the master webserver. I was wondering if I could define two save_paths so the machines look in their own session storage before using the network. For example: Master: session.save_path="tcp://localhost:11211, tcp://192.168.0.2:11211" Slave: session.save_path="tcp://localhost:11211, tcp://192.168.0.1:11211" Would this successfully share sessions across the servers AND help performance? i.e save network traffic 50% of the time. Or is this technique only for failovers (e.g. when one memcache daemon is unreachable)? Note: I'm not really asking specifically about memcache replication - more about whether the PHP memcache client can peak inside each memcache daemon in a pool, return a session if it finds one and only create a new session if it doesn't find one in all the stores. As I'm writing this I'm thinking I'm asking a bit much from PHP, lol... Assume: no sticky-sessions, round-robin load balancing, LAMP servers.

  • Sendmail doesn't work with iptables, even though smtp and dns are allowed

    - by tom
    I have sendmail installed on Ubuntu 10.04 solely for the use of the php mail() function. This works fine unless iptables is running (I've been using sendmail [email protected] to test this). I think that I have allowed SMTP and DNS (the script I am using to test iptables rules is below, in my version are the actual IPs of my hosts nameservers), but to no avail! iptables --flush iptables -A INPUT -p tcp --dport 22 -j ACCEPT iptables -A INPUT -p tcp --dport 80 -j ACCEPT iptables -A INPUT -p tcp --dport 443 -j ACCEPT # Postgres iptables -A INPUT -p tcp --dport 5432 -j ACCEPT # Webmin iptables -A INPUT -p tcp --dport 10000 -j ACCEPT # Ping iptables -A INPUT -p icmp --icmp-type echo-request -j ACCEPT iptables -A OUTPUT -p icmp --icmp-type echo-reply -j ACCEPT # sendmail iptables -A INPUT -p tcp --dport 25 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --sport 25 -m state --state ESTABLISHED -j ACCEPT # DNS iptables -A INPUT -p udp --sport 53 -s <nameserver1> -j ACCEPT iptables -A INPUT -p udp --sport 53 -s <nameserver2> -j ACCEPT iptables -A INPUT -p tcp --sport 53 -s <nameserver1> -j ACCEPT iptables -A INPUT -p tcp --sport 53 -s <nameserver2> -j ACCEPT iptables -A OUTPUT -p udp --dport 53 -d <nameserver1> -j ACCEPT iptables -A OUTPUT -p udp --dport 53 -d <nameserver2> -j ACCEPT iptables -A OUTPUT -p tcp --dport 53 -d <nameserver1> -j ACCEPT iptables -A OUTPUT -p tcp --dport 53 -d <nameserver2> -j ACCEPT iptables -A INPUT -j DROP # Add loopback iptables -I INPUT 1 -i lo -j ACCEPT

  • Configuring ZenOSS to monitor CPU load

    - by Tom
    I'm trying test out monitoring tools for a network at work with a coworker but neither of us have ever used an sort of monitoring tools before. Currently we are experimenting with ZenOSS and having some difficulties. We want to populate our CPU load graphs because that is one of the primary feature we are looking for in our monitoring tools but we have been unable to populate the graphs with data. So far we have installed the wmipreformance, sqldatasource, wmidatasource, snmpperformance(simple) zenpacks and the machine we are trying to monitor is running Windows XP. We have tried to model the device and everything seems to run and we've tride to add data points to graphs but the only options we recieve for graphs are CPU and Memory. We are able to monitor services, ZenOSS recognizes the make and model of the processor, RAM, and Harddrive and is even giving us metrics on available storage but again, we are looking for performance metrics such as CPU load and Memory utilization. I realize I probably didn't provide a lot of information but that is because we don't have a very good idea of what we are doing and can't find instruction either on the ZenOSS homepage or forums to monitor CPU load. If someone could give us step by step instruction on how to set up CPU load monitoring that would probably be more beneficial to us than a diagnostic of our current setup, but regardless, if I left any important information out and you need it to answer the question, please let me know. Thank you.

  • How do I add a shapefile in ArcGIS via python scripting?

    - by Tom W
    I am trying to automate various tasks in ArcGIS Desktop (using ArcMap generally) with Python, and I keep needing a way to add a shape file to the current map. (And then do stuff to it, but that's another story). The best I can do so far is to add a layer file to the current map, using the following ("addLayer" is a layer file object): def AddLayerFromLayerFile(addLayer): import arcpy mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] arcpy.mapping.AddLayer(df, addLayer, "AUTO_ARRANGE") arcpy.RefreshActiveView() arcpy.RefreshTOC() del mxd, df, addLayer However, my raw data is always going be shape files, so I need to be able to open them. (Equivantly: convert a shape file to a layer file wiothout opening it, but I'd prefer not to do that).

  • DNS issue on Fedora 12? wget wordpress.org fails where wget www.google.com works

  • Oracle Hangs on Responses Intermittently

    - by Ryan Cook
    I want to preface this with the fact that I am a developer and I am not even close to a DBA, plus I am new to Oracle. OK, here it goes: I have a Java application which uses spring and hibernate. Its a simple CRUD app and I will leave the details out as I don't think they are the issue. I have noticed that my app runs fine when I use MySql, but when I use an Oracle 10.2 server every 7th-10th hangs for 5-10 seconds. My Oracle installation was done by me using all defaults, same as the mysql install. I don't even know where to start looking. Any ideas? Thanks in advance and sorry that I lack the details that are most likely required for help.

  • Ruby on Rails cannot find Initializer?

    Hello, I am trying to deploy an app to a fresh Ubuntu 10 installation using Passenger 2.2.15, Rails 2.3.5, Ruby 1.8.7, and Apache 2.2.14. However, even with a default rails app (sudo rails defaultapp), I am receiving the following error: "no such file to load -- initializer".

  • How can I set environment variables for a graphical login on linux?

    - by Ryan Thompson
    I'm looking for a way to set arbitrary environment variables for my graphical login on linux. I am not talking about starting a terminal and exporting environment variables within the terminal, because those variables only exist within that one terminal. I want to know how to set an environment variable that will apply to all programs started in my graphical session. In other words, what's the Xorg equivalent of ~/.bash_login?

  • Understanding the Mounting of a Filesystem

    - by Tom H.
    I'm new to linux and want to check my understanding of how mounting/filesystems work. I read related manpages, but just want to be sure. I have a partition say /dev/sda5 that is currently mounted to /home with various subdirs. It is my understanding that this means /dev/sda5 has its own portable filesystem that can be moved anywhere in the main filesystem. Questions: If I unmount /dev/sda5 from /home (# umount /home) and then mount it to /var/www/ (which is empty) (# mount -t ext3 /dev/sda5 /var/www) and replace the fstab entry, with /dev/sda5 /var/www ext3 defaults,noatime,nodev 1 2 and # mount -a, Q1) are all of the contents of /home now accessible under /var/www/ (i.e. /home/username -> /var/www/username)? Q2) Are all of the permissions from the /home filesystem kept intact in this new location? Anything else I should be concerned with? Just want to make sure I don't go wipe/corrupt anything. Coming from Windows the filesystem architecture takes getting used to (though I'm loving the flexibility!).

  • PostgreSQL 9.1 on Ubuntu Lucid fails to start - how to debug?

    - by Tom Fakes
    I'm using Vagrant with Chef Solo to setup a Lucid 64 box. I'm using a Chef recipe to install PostgreSQL 9.1 from Martin Pitt's backports. The install goes ok until the point where the database is started with /etc/init.d/postgresql start There's a log pause and the command fails. If I run pg_ctl manually, the database starts! The entire contents of my postgresql-9.1-main log file is: 2012-05-07 11:01:18 PDT LOG: database system was shut down at 2012-05-07 11:01:16 PDT 2012-05-07 11:01:18 PDT LOG: database system is ready to accept connections 2012-05-07 11:01:18 PDT LOG: autovacuum launcher started 2012-05-07 11:01:18 PDT LOG: incomplete startup packet 2012-05-07 11:01:26 PDT LOG: received fast shutdown request 2012-05-07 11:01:26 PDT LOG: aborting any active transactions 2012-05-07 11:01:26 PDT LOG: autovacuum launcher shutting down 2012-05-07 11:01:26 PDT LOG: shutting down 2012-05-07 11:01:26 PDT LOG: database system is shut down I've tried to change the postgresql config file to get more info into the logfile, but that hasn't worked at all.

  • Load balancing without a load balancer?

    - by Tom
    I have 4 nginx-powered image servers on their own subdomains which users would access at random. I decided to put them all behind a HAProxy load balancer to improve the reliability and to see the traffic statistics from a single location. It seemed like a no-brainer. Unfortunately, the move was a complete failure as the load balancer's 100mbit port was completely saturated with all requests now going through it. I was wondering what to do about this - I could get a port upgrade ($$) or return to 4 separate image servers that are randomly accessed. I thought about putting HAProxy on each image server which would in turn route to another image server if that server's nginx service was having trouble. What would you do? I would like to not have to spend too much additional money.
