• Sync desktop Mac environment to laptop

  - by Andrew Vit

  I spend the majority of my time working at my desktop Mac, which I have configured for my web development environment. My spouse has a MacBook for casual use, and I occasionally steal it back when I need to work off-site, or when travelling. The question is how to best synchronize the two so I can switch between them more readily. I've solved a few obvious things by using online services: Email is hosted on IMAP. Working files are in Dropbox. Source code is managed in git. However, the following are things I always miss when jumping on the laptop: Installed Applications (current versions) Installed libraries & utilities (/usr/local) Apache VirtualHosts & other configurations (/etc) Disk image files for VMs My current method is to connect the MacBook via Firewire target mode and rsync the /Users/me home directory, and then cherry-pick the other items I need from Applications, /etc and /usr/local. The problem with this method is that it can be very time consuming due to things like my virtual machine image files, cached emails, etc. How can I make this faster & easier? Can you recommend a solution for configuration management (so I can repeatably install & configure the same software on both), or synchronization (so I can bring the MacBook up to date nightly, over our home network)?

• Map a domain to another subdomain - Rackspace

  - by Gorgi Rankovski

  I am using a subdomain as a parameter to an ASP.NET MVC 4 application. It's working well. Now I need to test my approach, so I have the application hosted on appharbor. It works well with subdomains here too. Our DNS registers are on Rackspace, but I have no control over it. Another guy is responsible for that. So, myapp.apphb.com can be accessed through myapp.com. Also abc.myapp.com is working as expected. I use abc as a parameter. So, now I want abc.com to be mapped in those Rackspace DNS registers to abc.myapp.com Is this possible at all? Can you explain to us how to do that? Will I have some problems with it? Anything that I should be aware of? Please have in mind that I am newbie when it comes to DNS. And no experience with Rackspace. Thanks.

• Understanding what needs to be in place for a server to send outgoing email from a linux box

  - by Matt

  I am attempting to configure an openSuse 11.1 box to send outgoing email for a domain that the same server is hosting. I don't understand enough about smtp servers and the like to know what needs to be in place and working. The system already had Postfix installed, and I confirmed it was running via a > sudo /etc/init.d/postfix status I examined the Postfix config file in /etc/main.cf and configured a couple of items regarding the domain/host name and such, but left it largely default. I attempted to send an email from the command line with the following command: > echo "test 123" | mail -s "test subject" [email protected] Where differentdomain.com was not the same domain as the one best hosted on the server. However, the email never reaches the target account. Any suggestions? EDIT: In the postfix log, (/var/log/mail.info, there's nothing in .err) I see that postfix is trying to connect to what appears to be a different smtp server on our network, with a connection refused: connect to ourdomain.com.inbound15.mxlogic.net[our ip address]:25: Connection refused However, I can't figure out why it is 1) trying to connect to that server and 2) not just sending the messages itself... I mean, isn't postfix an smtp server? I did a grep -ri on ourdomain from /etc and see no configuration files anywhere telling it to do this. Why is it?

• Hyper-V Guests Dying

  - by Jon Rauschenberger

  I just hit my THIRD instance of a Hyper-V guest machine dying with the exact same behavior. In all three instances we are hosting WS2008 guests on a WS2008 host. AFter a config change, we reboot the guest and the guest OS comes up but in a very cripled state. Specifically, we are able to log into the guest, but can't launch any apps and the guest never comes active on the network. I opened a support ticket with MS the second time this happened and they focused in on the DCOM subsystem not coming up...best explanation they could provide was that permissions on key system files got corrupted. I eventually gave up on the ticket after close to 10 hours on the phone trying different things that were going no where. What really concerns me is that we have now seen the exact same thing happen to a guest hosted on a completly differet host machine. There is zero hardware overlap between the two. Has anyone seen this before?? It's really odd behavior, but it also seems like there's a pattern here that's concerning me. Thanks, jon

• Dual Monitor support rdp 7 to win 7 on esxi

  - by rphilli5

  I am trying to RDP from a Windows 7 Professional dual monitor physical machine to a Windows 7 Professional VM hosted on esxi 4.0. I can get the spanning option to work to both monitors, but I have tried 3 different methods of connecting but have not been able to use true multiple monitors. At different times, I tried checking the "use all monitors" option, command line mstsc /multimon and added the line use multimon:i:1 to the .rdp file. None of these worked. Any ideas? The physical machine can connect to other Windows 7 physical machines with true multi monitor access. I also have the same issue when going from a 32bit RC1 machine to a Windows 7 Professional x64, but not when going in the reverse direction. Here's the .rdp: screen mode id:i:2 use multimon:i:1 desktopwidth:i:1440 desktopheight:i:900 session bpp:i:16 winposstr:s:0,1,341,118,1139,568 compression:i:1 keyboardhook:i:2 audiocapturemode:i:0 videoplaybackmode:i:1 connection type:i:1 displayconnectionbar:i:1 disable wallpaper:i:1 allow font smoothing:i:0 allow desktop composition:i:0 disable full window drag:i:1 disable menu anims:i:1 disable themes:i:1 disable cursor setting:i:0 bitmapcachepersistenable:i:1 full address:s:192.168.1.5 audiomode:i:0 redirectprinters:i:1 redirectcomports:i:0 redirectsmartcards:i:1 redirectclipboard:i:1 redirectposdevices:i:0 redirectdirectx:i:1 autoreconnection enabled:i:1 authentication level:i:2 prompt for credentials:i:0 negotiate security layer:i:1 remoteapplicationmode:i:0 alternate shell:s: shell working directory:s: gatewayhostname:s: gatewayusagemethod:i:4 gatewaycredentialssource:i:4 gatewayprofileusagemethod:i:0 promptcredentialonce:i:1 use redirection server name:i:0 drivestoredirect:s:

• For Australian audiences, would an uncached .com.au domain resolve faster than an uncached .com?

  - by thomasrutter

  Is there any speed benefit to using a .com.au domain rather than a .com if your customers, hosting and DNS services are in Australia, specifically in the worst typical case (domain is not cached in any local DNS relay for customer)? Assuming that both domains pointed to the same nameservers in the end. I know this is mostly academic because we are talking about a DNS lookup that would take at most a few hundred milliseconds and would only be relevant once at the beginning of a session. I just was curious. I know that an uncached .com lookup will involve consulting at least one ?.gtld-servers.net. server and an uncached .com.au will involve consulting at least one ?.au. server. Now, what I guess I'd need to know is Are the various ?.gtld-servers.net. servers using anycast technology that would have local fully authoritative nodes in Australia, making them just as fast to Australians as ?.au. and avoiding a 200ms+ overseas latency, or are some or all of them hosted only in the US or in the northern hemisphere?

• Occasional "Could not load file or assembly" in asmx WebService on IIS and DFS

  - by jesse-mcdowell

  We have a handfull of ASMX web service hosted on two identical Windows Server 2003 boxes. The virtual directory for the web services is loaded in a DFS share, both servers point to the same share. We have a load balancer between the internet and the two web servers. At a seemingly random interval (right now about twice per week) when a user tries to access a method on the web service, IIS returns the error: "Could not load file or assembly" for one of the assemblies used in the method call, and will continue reporting it each time the method is called until the app pool is recycled. We haven't found any distinguishable pattern to the problem. This is what I know: the missing assembly varies (but it's always a home-brew assembly) the Web Service method that fails varies there is no noticeable pattern to the times or intervals where the problem appears there are no admin users accessing the servers when the problem appears the failing method will work correctly on one server and fail on the other, even though both point to the same bin folder the problem can always be corrected by recycling the app pool and making no other changes I have enabled the Assembly Binder Log, and know that the binder is looking in the correct location for the file. Our assemblies are compiled for .Net 3.5.

• Does WebDAV even work on IIS 7? I say nay

• Windows 7 Users unable to add Windows 2003 server printers

  - by TravBrack

  Hi there I just rolled out a few Windows 7 x64 machines and ran into this issue where non-admin users are unable to add printers hosted on a windows 2003 server. It works fine on a 2008 server. The issue appears to be with the point and print system. A user will attempt to add the printer, a prompt will come up requiring the user to elevate privileges in order to install a driver, and will fail citing 'access denied'. I found the group policy setting Point and Print Restrictions: When the policy setting is disabled: -Windows Vista computers will not show a warning or an elevated command prompt when users create a printer connection to any server using Point and Print. So I disabled it, verified that the policy was being picked up using rsop, but it still does the same thing. I've also tried the following: Recreating the printers using newer drivers Adding the printer using 32 bit drivers on the 2003 machine, then adding the 64 bit drivers on a Windows 7 machine Adding the printer from a windows 7 machine using print management None of these things work. The security settings are no different than the working printers. Help?

• Server reporting incorrect mime type for css files

  - by Becky

  We have a VPS server that we host our websites on. I have written a CMS using CodeIgniter. On one of the interfaces, I am attempting to upload a css file to the system. This worked correctly when we had it hosted on shared hosting. Since we've moved it to the VPS, I am getting an "incorrect filetype" error. It all comes down to the fact that the server is reporting a mime type of text/x-c for the css file rather than text/css. I logged in via shell and ran the following command on an existing valid css file (to make sure it wasn't an issue with either CodeIgniter or with php). file --brief --mime 'filename.css' 2>&1 The server gave me the following in response to my command: text/x-c; charset=us-ascii My question ... is there some sort of server setting that I need to tweak to get the server to correctly identify the css file as text/css? Do I just have to add a mime type for the css files to the server? I found the mime types file (etc/mime.types), and it just hase video types and a couple other that I have no idea what they are. There is nothing in there for css or images or html files. Unless I'm looking in the wrong spot. I'm not a server person, so I'm hoping someone can help me out. Some server specs: Apache/2.2.22 (Unix) php 5.3.13 Server API = CGI/FastCGI the fileinfo php extension appears to be disabled

• Changing Domain Name DNS to Redirect web traffic to one server, and leave mail to original server

  - by David S

  Hi there, Ok, quite the idiot with DNS.. apart from the basics. I have a domain name hosted with a domain registrar. It seems to have full DNS control (i.e. ability to view/edit A Records, Mail etc..) We have recently setup a server at Rackspace which hosts the new website The original/existing server (where the old website still is and Mail) is on another shared hosting companies server I went to the domain name registrar, and checked out the DNS management as follows: click here to view the DNS screenshot So obviously the A Record is pointing to the actual server where the website/mail is I figure, and the CNAME is pointing (alias?) to the website url. So my question is this: If I want the web traffic portion to go to the Rackspace/new server, but keep the mail going to where it is now, what do I have to change? Also, should I even change this info at the domain registrar? the rackspace server account has full DNS which seems to suggest I can point to their nameservers and then re-direct the MX (Mail) traffic to where the mail server is? Sorry if that was a bit confusing.. obviously in need of DNS training ;) Any help very appreciated. David.

• Error 53 - The network path was not found.

  - by Jack

  I have a machine in my Active Directory Domain that I can no longer "net view" from other machines in the domain. This is a Windows XP Pro machine. It is hosting a VMWare virtual of my Domain Controller. If I attempt to net view [machine name] I get system error 53, The network path was not found. This is not a DNS issue, the same thing happens with the machine's IP. I don't think it's a firewall issue, I turned the firewall off on this machine. As I mentioned, it has worked in the past, and then stopped for no reason that I can see. I (intentionally) didn't change the software. I CAN get to the VMs hosted on this machine, can connect to their shares, net view them, etc. All other machines can see each other. In fact, the problem machine can see other machines and access their shares just fine. I tried removing the machine from the domain and re-adding it. I tried deleting the shares and recreating them. Not sure how to troubleshoot this any further. Any ideas?

• nginx proxy_pass POST 404 errors

  - by Scott

  I have nginx proxying to an app server, with the following configuration: location /app/ { # send to app server without the /app qualifier rewrite /app/(.*)$ /$1 break; proxy_set_header Host $http_host; proxy_pass http://localhost:9001; proxy_redirect http://localhost:9001 http://localhost:9000; } Any request for /app goes to :9001, whereas the default site is hosted on :9000. GET requests work fine. But whenever I submit a POST request to /app/any/post/url it results in a 404 error. Hitting the url directly in the browser via GET /app/any/post/url hits the app server as expected. I found online other people with similar problems and added proxy_set_header Host $http_host; but this hasn't resolved my issue. Any insights are appreciated. Thanks. Full config below: server { listen 9000; ## listen for ipv4; this line is default and implied #listen [::]:80 default_server ipv6only=on; ## listen for ipv6 root /home/scott/src/ph-dox/html; # root ../html; TODO: how to do relative paths? index index.html index.htm; # Make site accessible from http://localhost/ server_name localhost; location / { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. try_files $uri $uri/ /index.html; # Uncomment to enable naxsi on this location # include /etc/nginx/naxsi.rules } location /app/ { # rewrite here sends to app server without the /app qualifier rewrite /app/(.*)$ /$1 break; proxy_set_header Host $http_host; proxy_pass http://localhost:9001; proxy_redirect http://localhost:9001 http://localhost:9000; } location /doc/ { alias /usr/share/doc/; autoindex on; allow 127.0.0.1; allow ::1; deny all; } }

• Make Nginx fail when SSL certificate not present, instead of hopping to only available certificate

  - by Oli

  I've got a bunch of websites on a server, all hosted through nginx. One site has a certificate, the others do not. Here's an example of two sites, using (fairly accurate) representations of real configuration: server { listen 80; server_name ssl.example.com; return 301 https://ssl.example.com$request_uri; } server { listen 443 ssl; server_name ssl.example.com; } server { listen 80; server_name nossl.example.com; } SSL works on ssl.example.com great. If I visit http://nossl.example.com, that works great, but if I try to visit https://nossl.example.com (note the SSL), I get ugly warnings about the certificate being for ssl.example.com. By the sounds of it, because ssl.example.com is the only site listening on port 443, all requests are being sent to it, regardless of domain name. Is there anything I can do to make sure a Nginx server directive only responds to domains it's responsible for?

• Ubuntu 10.04 server delay responding to AJAX requests

  - by DanielAttard

  I manage a Ubuntu 10.04 server with a couple of domains hosted on it. As I continue to learn more about all these wonderful new (for me), one issue that I have begun to notice is the delay it sometimes takes for the server to respond to certain requests. As an example, when I view the timeline of events using firebug I can see that most of the time when I make a POST, the server responds in under 100ms. Sometimes, however, there is a substantial delay before the RESPONSE from the server. I can't seem to tell when the delay will happen and when it won't, however, when it happens the delay is always for about 4.5 seconds. The delay seems to happen about 30-40% of the time. Here is the section of apache2.conf dealing with logs: # # The following directives define some format nicknames for use with # a CustomLog directive (see below). # If you are behind a reverse proxy, you might want to change %h into %{X-Forwarded-For}i # LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%h %l %u %t \"%r\" %>s %O" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent I have no idea where to look to try and debug this problem or investigate further. Any suggestions?

• How do I set up DNS with nic.io to point to an AWS EC2 server?

  - by Chad Johnson

  I purchased a domain one week ago via nic.io. I have elected to provide my own DNS [because they provided no other option]. I'm trying to point my .io domain at my EC2 server instance. I've allocated an elastic IP and associated it with the instance. I can SSH into the instance and access point 80 via the IP address just fine. The IP is 54.235.201.241. nic.io support said the following: "You have selected to provide your own DNS and therefore if there is an issue with the set-up of the name servers you will need to contact your DNS provider." So, I created a Hosted Zone via Route 53 in AWS. This created NS and SOA records. I then set the Primary and Secondary servers at nic.io's domain admin page to the SOA record domains. Additionally, I set the optional servers to the NS domains. I did this two days ago, and I can't access the server via the domain. I ran a DNS check here...still not sure what I need to do: http://mydnscheck.com/?domain=chadjohnson.io&ns1=&ns2=&ns3=&ns4=&ns5=&ns6=. I have no idea what I'm supposed to do. Does anyone have any ideas?

• Nginx - Enable PHP for all hosts

  - by F21

  I am currently testing out nginx and have set up some virtual hosts by putting configurations for each virtual host in its own file in a folder called sites-enabled. I then ask nginx to load all those config files using: include C:/nginx/sites-enabled/*.conf; This is my current config: http { server_names_hash_bucket_size 64; include mime.types; include C:/nginx/sites-enabled/*.conf; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; root C:/www-root; #charset koi8-r; #access_log logs/host.access.log main; location / { index index.html index.htm index.php; } # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } server{ server_name localhost; } } And this is one of the configs for a virtual host: server { server_name testsubdomain.testdomain.com root C:/www-root/testsubdomain.testdomain.com; } The problem is that for testsubdomain.testdomain.com, I cannot get php scripts to run unless I have defined a location block with fastcgi parameters for it. What I would like to do is to be able to enable PHP for all hosted sites on this server (without having to add a PHP location block with fastcgi parameters) for maintainability. This is so that if I need to change any fastcgi values for PHP, I can just change it in 1 location. Is this something that's possible for nginx? If so, how can this be done?

• RRAS NAT not working on a certain computer

  - by legenden

  This is driving me crazy. I have a virtualized W2K8 server running RRAS. Every other computer or server on the network can access the internet through the NAT except one. On one server, it just won't work. I can ping the ip address of the NAT gateway just fine, and everything else works. (SMB, etc) DNS, which is hosted by the same server, also works just fine. I have even reinstalled the OS on the problem server and it still doesn't work. Recap of the steps I tried: There are 3 network cards in the server, I tried every one and different switch ports. Not a hardware problem. Reinstalled W2K8 R2 on server with the problem, didn't help. Tried the IP of the internet gateway directly - this did work (!). But I need NAT to work. All firewalls are disabled. Removed computer from domain, deleted computer membership in Active Directory Users and Computers and added it back. Disabled all other network adapters and set a static ip and specified the gateway ip manually. When I tracert a public IP, the first hop (or any other hop) comes up as: C:\>tracert www.google.com Tracing route to www.l.google.com [209.85.225.106] over a maximum of 30 hops: 1 * * * Request timed out. 2 * * * Request timed out. From a different computer, on which NAT works, the first hop comes up as: tracert www.google.com Tracing route to www.l.google.com [209.85.225.105] over a maximum of 30 hops: 1 <1 ms * <1 ms xxxx [10.5.1.1] This is the most bizarre problem I ever came across, and I realize that it's a long shot asking it here given all the details, but I'm pulling my hair out. Maybe someone has an idea...

• Unix VPS server going down at almost the same time every day

  - by ronnz

  My server load seems to be really spiking and many times the server goes down at the same time each night (Around midnight). I have about 20 cPanel accounts hosted on it and have tried everything I know to try to find what is causing the issue. Some of the things I have tried: Combined all site access logs found in /etc/httpd/domlogs and cannot see anything unusual at the time of server going down. Checked most other logs in the var/log directory and found nothing indicating the issue at the time the server is going down. Checked cron logs and cannot see anything unusual.. See below. Last night CPU spiked to 7.5 at 00:14. What else can I be checking? How can I really monitor to find out the root cause?

• RemoteApp .rdp embed creds?

  - by Chris_K

  Windows 2008 R2 server running Remote Desktop Services (what we used to call Terminal Services back in the olden days). This server is the entry point into a hosted application -- you could call it Software as a Service I suppose. We have 3rd party clients connecting to use it. Using RemoteApp Manager to build RemoteApp .rdp shortcuts to distribute to client workstations. These workstations are not in the same domain as the RDS server. There is no trust relationship between domains (nor will there be). There is a tightly controlled site to site VPN between workstations and the RDS server, we're quite confident we have access to the server locked down. The remoteApp being run is an ERP application with its own authentication scheme. The issue? I'm trying to avoid the need to create AD logins for every end user when connecting to the RemoteApp server. In fact, since we're doing a remoteApp and they have to authenticate to that app, I'd rather just not prompt them at all for AD creds. I certainly don't want them caught up in managing AD passwords (and periodic expirations) for accounts they only use to get to their ERP login. However, I can't figure out how to embed AD creds in a RemoteApp .rdp file. I don't really want to turn off all authentication on the RDS server at that level. Any good options? My goal is to make this as seamless as possible for the end-users. Clarifying questions are welcome.

• Looking for a short term solution to improve website performance with additional server

  - by Tanim Mirza

  I am working with a small team to run an internal website running with PHP 5.3.9, MySQL 5.0.77. All the files and database are hosted on a dedicated Linux machine with the following configuration: Intel Xeon E5450 8 CPU cores @3.00GHz, 2992.498 MHz, Cache 6148 KB, Cent OS – Red Hat Enterprise Linux Server release 5.4 We started small and then the database got bigger and now the website performance degraded significantly. We often get server space overrun, mysql overloaded with too many calls, etc. We don't have much experience dealing with these issues. We recently got another server that we were thinking to use to improve performance. Since it has better configuration, some of us wanted to completely move everything to the new machine. But I am trying to find out how we can utilize both machine for optimized performance. I found options such as MySQL clustering, Load balancer, etc. I was wondering if I could get any suggestion for this situation "How to utilize two machines in short term for best performance", that would be great. By short term we are looking for something that we can deploy in a month or so. Thanks in advance for your time.

• How Could My Website Be Hacked

  - by Kiewic

  Hi! I wonder how this could happen. Someone delete my index.php files from all my domains and puts his own index.php files with the next message: Hacked by Z4i0n - Fatal Error - 2009 [Fatal Error Group Br] Site desfigurado por Z4i0n Somos: Elemento_pcx - s4r4d0 - Z4i0n - Belive Gr33tz: W4n73d - M4v3rick - Observing - MLK - l3nd4 - Soul_Fly 2009 My domain has many subdomains, but only the subdomains that can be accessed with an specific user were hacked, the rest weren't affected. I assumed that someone entered through SSH, because some of these subdomains are empty and Google doesn't know about them. But I checked the access log using the last command, but this didn't show any activity through SSH or FTP the day of the attack neither seven days before. Does anybody has an idea? I already changed my passwords. What do you recommend me to do? UPDATE My website is hosted at Dreamhost. I suppose they have the latest patches installed. But, while I was looking how they entered to my server, I found weird things. In one of my subdomains, there were many scripts for execute commands on the server, upload files, send mass emails and display compromising information. These files had been created since last December!! I have deleted those files and I'm looking for more malicious files. Maybe the security hold is an old and forgotten PHP application. This application has a file upload form protected by a password system based on sessions. One of the malicious scripts was in the uploads directory. This doesn't seem like an SQL Injection attack. Thanks for your help.

• can not connect to SQL running on amazon ec2 machine

  - by njj56

  I am using SQL managment studio 2008 running on an Amazon EC2 machine. I am unable to connect to the database in my asp.net application. The EC2 instance has been set to accept connections over the SQL port. I am also able to remote the machine as well as view websites hosted on the server. Listed below is part of the connection string relating to this instance. When the program is ran and this connection string is called, it returns tcp error 0 - no return response. it just times out. <add name="ProjectServer" connectionString="Data Source=*IP ADDRESS HERE*,1433;Initial Catalog=*Catalog Name*;User ID=IP-0A6ED514\Administrator;"/> I removed the ip and the catalog name for the example, but I am sure they are correct. The only thing that I could think may cause an error, is the differences in names between the user id and the server name - the server name is ip-0A6ED514\sharepoint but the user name is ip-0A6ED514\administrator when I log into the sql server manager on the EC2 instance. A password is not used. Not sure if I would need to leave in a blank string for password - also not sure if the difference between server name and user id to log in makes a difference. Any help is appreciated. Thank you. update - when this connection string is used with out the port, i get tcp provider error 40 - when the port is in there, i get error 0 edit- the sql server is using windows authentication - does this make a difference? Usually I always use SQL server authentication

• Debian Linux bridging router intermittently dropping packets [migrated]

  - by nomen

  My old Asus router died a few weeks ago, so I thought I'd set up my Debian box to deal with routing my home network. I have a few complications, but I adapted my configuration from a previously working configuration, and I don't see why I am having intermittent problems. But I am having them! Every so often, my SSH connections to the router (and to the Xen virtual machines hosted by the router) just drop. I am unable to use the router's dns server. I can't ping the router. Etc. (I can provide more details, but I'm not sure what will be helpful) /etc/network/interfaces: # The loopback network interface auto lo iface lo inet loopback # Gigabit ethernet, internal network auto eth0 allow-hotplug eth0 iface eth0 inet manual # USB ethernet, internet auto eth1 allow-hotplug eth1 iface eth1 inet dhcp # Xen Bridge auto xlan0 iface xlan0 inet static bridge_ports eth0 address 10.47.94.1 netmask 255.255.255.0 As I understand it, this is sufficient to create the network interfaces, and even do some switching between Xen hosts and my eth0 interface. I installed and configured Shorewall to manage routing: /etc/shorewall/zones fw firewall net ipv4 lan ipv4 /etc/shorewall/interfaces net eth1 detect dhcp,tcpflags,nosmurfs,routefilter,logmartians lan xlan0 detect dhcp,tcpflags,nosmurfs,routefilter,logmartians,routeback,bridge /etc/shorewall/policy net all DROP info fw net ACCEPT info all all REJECT info /etc/shorewall/rules DNS(ACCEPT) fw net DNS(ACCEPT) lan fw ... and so on, these all work, when the router is accepting traffic at all. /etc/shorewall/masq eth1 10.47.94.0/24 Can anybody help?

• OS X Apache giving 503 error for anything in /api directory

  - by WilliamMayor

  I have a locally hosted website that uses Smarty templates, I'm trying to get started on building an API for the site. I've used virtualhost.sh to create a local virtual host for this and other sites. I've discovered that if I put a directory called api at the root of any of these virtual hosts I will get a 503 error when I try to access anything inside. I am using mod-rewrite but so far only to append a .php extension when needed. Here are the error logs for a request: [Thu Feb 09 13:42:37 2012] [error] proxy: HTTP: disabled connection for (localhost) [Thu Feb 09 13:49:06 2012] [error] (61)Connection refused: proxy: HTTP: attempt to connect to [fe80::1]:8080 (localhost) failed [Thu Feb 09 13:49:06 2012] [error] ap_proxy_connect_backend disabling worker for (localhost) The middle line gave me a clue to look in my hosts file because why would a request go to [fe80::1]:8080? I commented out that line and tried again, this time the error was in connecting to the standard 127.0.0.1 localhost. I have concluded that perhaps there is some config file somewhere picking up the underlying request of localhost/api and pointing it somewhere other than my virtual host. At this point my ability to fix the problem fails me. Can anyone help?
