• Setting up Shibboleth to secure part of a website

  - by HorusKol

  I've installed the Shibboleth module for apache on Ubuntu 10.04 using aptitude to install libapache2-mod-shib2 as per https://groups.google.com/group/shibboleth-users/browse_thread/thread/9fca3b2af04d5ca8?pli=1 and enabled the module (I have checked in /etc/apache2/mods-enabled) I then proceeded to secure a directory on the server by placing a .htaccess file with the following directives: AuthType shibboleth ShibRequestSetting requireSession 1 Require valid-user Now - I haven't set up an SSL host yet - and I also haven't set up the IdP - but I would expect that the server would block access to this directory - but I'm getting the content without any problems. I have restarted the apache service and I have no errors in the log files.

• Windows 7 Bootcamp to see data doubler SATA SSD in Optical Bay Connector

  - by bumble_bee_tuna

  Hi I purchased a OWC data doubler http://eshop.macsales.com/item/OWC/DDAMBS0GB/ ... Long story short it lets you add a second HD to your macbook pro in place of the cd/dvd drive (which is useless anyway, impossible to get stuff out when stuck). My current setup is 600gb intel SSD bootdrive 100gb partition for OSX / 500gb for Windows 7 Prof from Bootcamp (use 99 % of time). My desire is to have a second 300gb SSD to run disk intensive VM's off of. So I added a second 300gb intel SSD (again, NO desire to boot off of) on the sata optical port. I can see the drive no problem if I boot in to OSX, however, can't see it in disk management on Win7 ??? Any ideas similar experience ... Funny thing is I can see it in "Device Manager Disk Drivers" but not Disk Management ??? Also no I don't want to use Fusion/Parallels this is a waste of resources for me.

• Photoshop / Illustrator Fill text box with large string.

  - by Xetius

  I have a massive string (lots of Fibonacci numbers concatenated together). I don't know how much of this text I need to fill an A4 page. What I was hoping for was to paste a large block into a text box and have it display as much as possible, wrapping the text at the end of a line, but it is not doing that. It is just displaying a blank box (With the text overflowing into an awaiting textbox or something. I have tried pasting smaller amounts of text into the text box, and it appears that it will get about half way and then go into 'blank' mode. All I need is a simple way of creating a background of numbers which I don't have to type in. Any ideas?

• Dell 620 display is too bright to use

  - by keith

  I have a Dell D620 with a display problem. In windows 7 the display seems to be too bright, the text is broken up, the only way to see the mouse is at a very oblique angle. Changing the brightness with fn and brightness control has little/no effect. When I put it in high contrast mode I can see all the colors, but any windows pictures etc are still useless. I cannot get it to connect to an external monitor via VGA port or via a USB-VGA connector.

• How to Use 3 Monitors

  - by The.Anti.9

  Right now my setup has a nice big 24" flatscreen in the center, and a 19" flatscreen to the left. And a big gaping hole on the right. I have a 3rd monitor to put there, but I'm not sure how to get the computer to recognize it. Do I need a graphics card with 3 ports? Or can I span the monitors over non SLI-Linked graphics cards? Is it possible to plug my 3rd monitor into the on-board VGA port and have it work?

• Accessing Windows 7 Printer from Ubuntu Linux via LPR/LPD or Samba

  - by nitbuntu

  Hi, I'm having difficulty printing from my Linux (Ubuntu 10.04) based PC to a printer connected to a Windows 7 machine. I was trying to connect using Samba (version 3.5.6) but this always brings up an authentication screen which never accepts any password I use. So I read somewhere that an alternative is to access the Windows printer via LPR/LPD. I added an LPR/LPD printer in Windows 7, but even within Windows 7, I am not able to print as the print que monitor shows as 'printer busy'. The printer in question is an Epson Stylus DX7400 and works fine when using the standard USB ports....but doesn't when I use with the LPR/LPD ports. I even opened up the TCP/IP port 515 in my McAfee firewall without any success. Any help with this would be highly appreciated. Additionally, does anyone have any idea how I can get Samba working for me?

• Can Remote Desktop be set up to use IPv6?

  - by Garrett

  I have both a Windows 7 Ultimate and a Windows XP Professional machine set up on my home network. I would like to be able to access them from school. Port forwarding is not currently an option (long story). Is there a way to set it so that I can RDP (yes it has to be RDP not something like TeamViewer or LogMeIn) over IPv6, possibly using Teredo? I have tried but I can't seem to get it working. Also I cannot ping these machines' IPv6 addresses. How can I get this set up?

• iptables NAT configuration

  - by Sarp Kaya

  Hello I am experiencing some issues with my iptables. Here's what I want to do: A(eth0)--------(eth0)B(eth2)---------------(eth2)C Brackets are interface names A,B and C are hosts. Now I would like to forward port number 80 of host C so that It would be accessed via host A. host A is 192.168.1.254 host C is 192.168.3.2 I intentionally ACCEPTed all FILTER chain options as the default policy because I wanted to make sure that NAT is working properly first. I enabled ip_forward. So here's what I have done: sudo iptables -A PREROUTING -t nat -p tcp - d 192.168.1.254 -j DNAT --to 192.168.3.2 However it is not working. What am I missing here?

• Setting up dual wireless routers

  - by JasCav

  I have two wireless routers (one is the router supplied by Verizon - MI424-WR ActionTek and the other is DD-WRT Buffalo router). I want to set them up so that I have the second router (Buffalo) on its own subnet and two SSIDs so I can put different devices on different routers and so I can put my web server on the first router and put most of my other computers behind the second router for a little extra protection in case of a compromise. From my understanding, I have to hook the two routers together so that the LAN from the Verizon router plugs into the WAN port of the Buffalo router. This is where I get stuck. What settings do I need to look for to setup the Buffalo on its own subnet? Do I need to do anything with the Verizon router, or are the configuration changes done to the Buffalo?

• Un-table a cell range in Excel 2007

  - by Joe

  In Excel 2007, if you highlight a block of cells and then "Format as Table", it doesn't just apply colors and formatting, it somehow marks those cells as being a table. Now I want to get rid of the table, but keep all the cells (i.e. keep the data). So I tried clearing the table style and formatting, but Excel still recognizes those cells as being a table. I can tell because: When I select a cell that was in the table, Excel still displays the "Table Tools / Design" tab I cannot merge cells that were in the table <- this is what's annoying me So, how do I un-table those cells? I want to keep all the cell data and formatting, but have Excel not recognize them as a table.

• apxs cannot install mod_cloudflare on centos

  - by Adam

  [ Linux - CentOS - Apache 2.2 - mod_cloudflare - apxs2 ] I have changed my nameservers to point to CloudFlare. The problem is that all the IP addresses are coming in as CloudFlare's. This is no good, because I have to monitor and block some specific traffic. mod_cloudflare is supposed to resolve this but I have been unable to get this installed. The command in the documentation uses apxs2. I can't figure out how to install this, or if it just means for 'apache 2.4'. I'm running 2.2.3, and I can use 'apxs'. When I run: apxs -aic mod_cloudflare.c I get the error apxs:Error: Command failed with rc=65536 Does this mean I need apxs2 or something else? How do I get mod_cloudflare working on my server? I appreciate any help, the documentation is vague and limited.

• The canonical "blocking BitTorrent" question

  - by Aphex5

  How can one block, or severely slow down, BitTorrent and similar peer-to-peer (P2P) services on one's small home/office network? In searching Server Fault I wasn't able to find a question that served as a rallying point for the best technical ideas on this. The existing questions are all about specific situations, and the dominant answers are social/legal in nature. Those are valid approaches, but a purely technical discussion would be useful to a lot of people, I suspect. Let's assume that you don't have access to the machines on the network. With encryption use increasing in P2P traffic, it seems like stateful packet inspection is becoming a less workable solution. One idea that seems to make sense to me is simply throttling down heavy users by IP, regardless of what they're sending or receiving -- but it doesn't seem many routers support that functionality at the moment. What's your preferred method to throttle P2P/BitTorrent traffic? My apologies if this is a dupe.

• Remote Desktop over SSH SOCKS proxy to bypass firewall

  - by scrumpyjack

  Hi folks, I'm trying to connect to a Windows server from my Mac using RDC2.1 for Mac. The problem is the server I need to connect to is guarded by the evil dragon - IP-based access control on a completely separate network. I have an IP I can get in on, but it's at my office (i.e. a completely separate network). Because that network isn't set up for VPN, I've set up a SOCKS proxy through an SSH tunnel (which is all working fine). (SSH proxy) Me (on my Mac) ----------> Office Linux box ----> Windows server (home network) (office network) (other network) From my Linux server in my office (the SSH server) I can telnet to port 3389 on the Windows server, no problem. But from my Mac I can't get so much as a squeak out of it. Any ideas?

• failure daemon and changing pid number

  - by Alessandra Bilardi

  proftpd, sshd and apache processes run with /etc/init.d/its-script on linux distro. I was monitoring 21, 22 and 80 ports with farm monitoring service: every 5 minutes service check each port and notify only failure. The failures were 5-6 times on 24h. It seems that someone kicks the switch sometimes.. I add monit and collectd monitoring and the monitoring about 21, 22 and 80 ports is every 1 minute. I do not receive farm monitoring service notify. I receive only monit notify about failure and/or succeed/changing pid number of proftpd, sshd or apache process. The failures are still 5-6 times on 24h. collectd monitoing about cpu, load average and each process is regular and there are no peaks. There is nothing kicks the switch but there is something which determines failure monitoring. is it a simple interference or is it indicative of some abnormality? What could cause these failures?

• FTP restrict user access to a specific folder

  - by Mahdi Ghiasi

  I have created a FTP Site inside IIS 7.5 panel. Now I have access to whole site using administrator username and password. Now, I want to let my friend access a specific folder of that FTP site. (for example, this path: \some\folder\accessible\) I can't create a whole new FTP Site for this purpose, since it says the port is being used by another website. How to create an account for my friend to have access to just an specific folder? P.S: I have read about User Isolation feature of IIS 7.5, but I couldn't find how to create a user just for FTP and set it to a custom path.

• Route an IP from WAN to a host on LAN on OpenWRT

  - by Zsub

  EDIT: I know how to use NAT, I specifically want the server to be reachable on two IP's, one private, one public, with the firewall of the OpenWRT in between, if feasible. At the office we have recieved a /29 from our ISP. The first address is reserved for their endpoint, so I'm free to use five addresses. We run a local network, so of course there is a router in between running OpenWRT to provide all hosts with (W)LAN (dhcp from a private range). However, we also have a server running OS X Server 10.6 (Snow Leopard) and I'd like that server to be accessible both from the LAN using a private IP as well as from the WAN on it's own public IP. Point of note is that the server only has one network port, so multiple NICs is not an option, unfortunately. How would I go about doing this?

• Setting up WAMP to run on a LAN

  - by Steve

  I've installed WAMP on a Windows 7 PC, and it is running fine locally, as localhost. I want PCs on the LAN to be able to view the local server. When they load my PC's IP address in their browser, they receive a "You don't have permission to access / on this server" error. I followed this guide, but the issue remains. To recap: I've added an inbound exception to Windows Firewall for port 80 for Private and Domain connections. I've edited Apache's httpd.conf to include: Listen 80 Listen 192.168.0.5:80 < Directory "c:/wamp/www/wordpress/" allow from all < /Directory I've edited httpd-vhosts.conf to include: < VirtualHost 192.168.0.5:80 DocumentRoot "C:/wamp/www/wordpress" < /VirtualHost Any ideas?

  I'm in the process of setting up OpenVPN on a VPS running Debian 6. I've walked step-by-step through this guide twice now, and I can't get the service to start. When I start the service, the error reported in the log file is: Cannot ioctl TUNSETIFF tun: Inappropriate ioctl for device (errno=25) I've searched the web a few times and I'm not finding anything helpful.

• Puppet: Conditional file source based on naming convention

  - by thinice

  I'm getting the ball rolling on puppet for my environment - and I'd like to have a conditional file resource based on whether or not the module itself contains a file based on a naming convention. So visually, assume a module named 'mysql' and it's layout: mysql/ /files /etc/ my.cnf my.hostname1.cnf my.hostname2.cnf /manifests init.pp ... So I'd like the block to verify if the resource for the module exists or not, and take action accordingly, in pseudo-terms: file { '/etc/my.cnf': if -f 'puppet:///mysql/etc/my.$hostname.cnf' { source => 'puppet:///mysql/etc/my.$hostname.cnf' } else { source => 'puppet:///mysql/etc/my.cnf' } } This way one wouldn't have to manage a csv file or the .pp file with a host specific case statement - is this possible?

• Configuring Nginx for Wordpress and Rails

  - by Michael Buckbee

  I'm trying to setup a single website (domain) that contains both a front end Wordpress installation and a single directory Ruby on Rails application. I can get either one to work successfully on their own, but can't sort out the configuration that would let me coexist. The following is my best attempt, but it results in all rails requests being picked up by the try_files block and redirected to "/". server { listen 80; server_name www.flickscanapp.com; root /var/www/flickscansite; index index.php; try_files $uri $uri/ /index.php; location ~ \.php$ { include fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/flickscansite$fastcgi_script_name; } passenger_enabled on; passenger_base_uri /rails; } An example request of the Rails app would be http://www.flickscan.com/rails/movies/upc/025192395925

• Which iptables rule do you think is a 'must have'

  - by Saif Bechan

  I have some basic iptable rules set up now for my vps. Just block everything except some default ports, 80,21,22,443. I do get brute forced a lot. I have heard that iptables is very powerful but I have not seen many use cases. Can you give me an example of a(some) rule(s) you always use and give a small example why. I can not find a general best practice post here on SF, if there is any I would like the link. If this is a duplicate I am sorry and it can be closed.

• Moving a Drupal between linux servers, best practice to avoid file-ownership problems

  - by zero

  I want to port over a Drupal commons 6x24 from a local LAMP-stack to a production webserver. Both systems run OpenSuse Linux. How do I do this, what are the most important steps. How should I handle file-ownership. It's important for me to have to have full control of the file ownership. If I use the wwwrun account, I frequently run into problems, due to a very strict webserver-admin. See for example the long history of looking for fixes and solutions see this thread and even more interesting see this very long and impressive thread here. All troubles I run into have to do with file-owernship and permissions. This is my current setup; Note: This was just a quick hacked installation - quick and dirty.

• Lightweight monitoring for a Windows XP laptop

  - by kazanaki

  Hello I have a windows XP laptop in a remote location. I would like to have an overview for CPU/Memory statistics from a remote location. Monitoring a specific service (a Tomcat instance) would be nice but not essential. I have seen the monitoring solutions (Nagios, cacti e.t.c) and they are all very heavy. I do not want to install mysql, web server and other stuff like that on the laptop. I don't even need a web solution at all. It could just be a simple command line app with a server port and on my machine another GUI application would connect there (and not a web browser) Is there something like this available?
