• Dell R320 RAID 10 with CacheCade

  - by Geekman

  I'm looking for a higher-performance build for our 1RU Dell R320 servers, in terms of IOPS. Right now I'm fairly settled on: 4 x 600 GB 3.5" 15K RPM SAS RAID 1+0 array This should give good performance, but if possible, I want to also add an SSD Cache into the mix, but I'm not sure if there's enough room? According to the tech-specs, there's only up to 4 total 3.5" drive bays available. Is there any way to fit at least a single SSD drive along-side the 4x3.5" drives? I was hoping there's a special spot to put the cache SSD drive (though from memory, I doubt there'd be room). Or am I right in thinking that the cache drives are simply drives plugged in "normally" just as any other drive, but are nominated as CacheCade drives in the PERC controller? Are there any options for having the 4x600GB RAID 10 array, and the SSD cache drive, too? Based on the tech-specs (with up to 8x2.5" drives), maybe I need to use 2.5" SAS drives, leaving another 4 bays spare, plenty of room for the SSD cache drive. Has anyone achieved this using 3.5" drives, somehow?

• 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.

• File uploads and client_max_body_size in nginx + gunicorn + django

  - by carlosescri

  I need to configure nginx + gunicorn to be able to upload files greater than the default max size in both servers. My nginx .conf file looks like this: server { # ... location / { proxy_pass_header Server; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_connect_timeout 60; proxy_pass http://localhost:8000/; } } The idea is to allow requests of 20M for two locations: /admin/path/to/upload?param=value /installer/other/path/to/upload?param=value I've tried to add location directives at the same level than the one I've pasted here (getting 404 errors) and also tried to add them inside the location / directive (getting 413 Entity Too Large errors). My location directives look like these in their simplest form: location /admin/path/to/upload/ { client_max_body_size 20M; } location /installer/other/path/to/upload/ { client_max_body_size 20M; } But they don't work (actually I tested lots of combinations and I'm desperate thinking about this. Please, help If you can: What settings do I need to set to make this work? Thank you so much!

• What applications do people use for windows folder management? How do you switch between folders in

  - by 118184489189799176898

  I'm always switching between client's folders in different applications like photoshop, sql manager, explorer etc. It's so slow to go between them, navigate to the folder and it's still too slow to copy and paste the directory etc. It's so annoying to do. Someone must have a good solution. I was thinking if there was a "recently accessed" folders list available within every folder explorer window... so in any application, if i go "file open" it will have something, somewhere that lists the recently accessed folders - that would be really helpful. I am aware of the recent places folder in win7, but this sucks because it is not sorted by date accessed. Perhaps if there was a way to change this then this would become a decent feature? Is there some application that already does this? i'm sure someone has already solved this issue in a more elegant solution than I can think off. I'm keen to know what programs people use or how people addresss this issue? Thanks...

• Disk Partitioning problem with fdisk.

  - by MA1

  Currently i am using fdisk to create/resize windows partitions. Following is a sample input script to fdisk to create/resize windows partitions: fdisk /dev/sda < partInput the contents of partInput are as follows: d #delete the partition 3 #partition number to be deleted n #add a new partition p #primary: type of new partition 3 #new partition number 18804 #start cylinder of new partition 77433 #end cylinder of new partition t #change the type of partition 3 #partition number whose type(filesystem) is to be changed 7 #HPFS/NTFS: partition type(filesystem) n #add a new partition p #primary: type of partition 77434 #first cylinder of new partition 77825 #end cylinder new partition w #write all the above changes As you see in the above input we are using cylinders for start and end. Earlier i am using sectors as unit and everything is working fine but getting problems when partitioning a 1.5TB hard drive. Then i changed the unit to cylinders but it is working on some machines not all. On some machines fdisk failed to create the partition table correctly. So, i am thinking to move to parted if there is no way to do the above using fdisk. Please also tell me how to correctly convert sectors to cylinders? How to perform all the above steps using parted without losing the data OR how to use fdisk correctly?

• What is the best way to connect a 3 switches with a router?

  - by Carlos Morales

  Hello everyone, I'm trying to rebuild the network from my work and I was thinking what is the best way to connect three switches and a router. The router has 4 ports so I thought to connect 2 switches to the router (each switch connected with 2 cables to the router) and then connect the third switch to one of the others with two cables. So is like this, two cables from switch one to the router, two cables from switch two to the router and two cables from switch 3 to switch 1 or 2. So my questions are: Is it better to connect the router to each switch with a cable or the more cables you have the better? If I connect the switch 3 to switch 1 or 2 is it better to connect it with a cable or you get better performance with more cables. If I'm wrong and there is a better or more efficient way to connect them please let me know. The router is a Netgear RP114 (I'll upgrade it to a Sonicwall NSA 240), switch 1 is a Netgear GS748T, switch 2 is a Cisco Catalyst 2924-XL and switch 3 is a D-link DGS-1024D Thank you very much

• open-source LAMP package for simple accouting and receiving?

  - by user26664

  Hello. I am involved with a computer-based charity where we take donation of old equipment, often recycle it, mostly rehabilitate it and make it available through grants and 'adoptions', and sell some items. What we're looking for is a LAMP package that can handle our records of donations of equipment, print receipts for donators, and also track our thrift store sales with receipts. Donators will want receipts of their donations for tax deduction purposes. We'll want to print reports of incoming items from time to time, say monthly and yearly. For the thrift store, we'll also need receipts for that, reports of cash, especially for reconciling cash drops, and also reports of items sold from time to time. I'm thinking this might be a single package, but it might be two. We don't want to track our shop inventory with either of these programs -- that's another program/project. We just need to know what was donated and what was sold. It must be open source, and ideally we'd like it to run on LAMP -- Linux, Apache, MySQL, PHP, but we will consider other open-source platforms.

• tail -f and then exit on matching string

  - by Patrick

  I am trying to configure a startup script which will startup tomcat, monitor the catalina.out for the string "Server startup", and then run another process. I have been trying various combinations of tail -f with grep and awk, but haven't got anything working yet. The main issue I am having seems to be with forcing the tail to die after grep or awk have matched the string. I have simplified to the following test case. test.sh is listed below: #!/bin/sh rm -f child.out ./child.sh > child.out & tail -f child.out | grep -q B child.sh is listed below: #!/bin/sh echo A sleep 20 echo B echo C sleep 40 echo D The behavior I am seeing is that grep exits after 20 seconds , however the tail will take a further 40 seconds to die. I understand why this is happening - tail will only notice that the pipe is gone when it writes to it which only happens when data gets appended to the file. This is compounded by the fact that tail is to be buffering the data and outputting the B and C characters as a single write (I confirmed this by strace). I have attempted to fix that with solutions I found elsewhere, such as using unbuffer command, but that didn't help. Anybody got any ideas for how to get this working how I expect it? Or ideas for waiting for successful Tomcat start (thinking about waiting for a TCP port to know it has started, but suspect that will become more complex that what I am trying to do now). I have managed to get it working with awk doing a "killall tail" on match, but I am not happy with that solution. Note I am trying to get this to work on RHEL4.

• Configure one IIS site to handle two separate SSL certificates using external Load Balancing or SSL Acceleration Servers

  - by bmccleary

  I have one web application on our server that needs to be referenced by two different domain names, both of which have their own SSL certificates. The application is exactly the same for both domains, but we have to keep the two domain names for legal reasons. The problem is that, since both domains need to have their own SSL certificate, that inside of our IIS 7.5 configuration we have to have two separate IIS applications (both pointing to the same physical location) with their own unique IP address and SSL certificate installed. Now, I know that, due to the nature of SSL communications, that this is by design and that you can't assign more than one SSL certificate per IP address and domain name. My question is… is there any way around this limitation and keep one web application in IIS and have it service two SSL certificates based on host name? I know that with the basic IIS configuration that this is not possible, but I was thinking that with some sort of combination of external load balancing and/or SSL acceleration servers/services that we could have these servers process the SSL request and leave IIS clean to have one single application. I am not familiar at all with these technologies, hence the reason I am asking if it is theoretically possible. If not, does anyone else know how to achieve this?

• Upgrading MySQL Connector/Net

  - by Todd Grover

  I am trying to publish a website with our hosting provider. I am getting error due to the fact that they only allow a medium trust and the MySQL Connector/Net that I am using requires reflection to work. Unfortunately, reflection is not allowed in a medium trust. After some research I found out that the newest version of the MySQL Connector/Net may solve this problem. Connector/Net 6.6 includes enhancements to partial trust support to allow hosting services to deploy applications without installing the Connector/Net library in the GAC. I am thinking that will solve my problem. So, I unistalled MySQL Connector/Net 6.4.4 and I installed MySQL Connector/Net 6.6.4. When I run the application in Visual Studio 2010 I get the error: ProviderIncompatibleException was unhandled by user code The message is An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct. InnerException is The provider did not return a ProviderManifestToken string. Everything works fine when I have Connector/Net 6.4.4 installed. I can access the database and perform Read/Write/Delete action against it. I have a reference to the following in the project: MySql.Data MySql.Data.Entity MySql.Web My connection string in Web.config <connectionStrings> <add name="AESSmartEntities" connectionString="server=ec2-xxx-xx-xxx-xx.compute-1.amazonaws.com; user=root; database=nunya; port=3306; password=xxxxxxx;" providerName="MySql.Data.MySqlClient" /> </connectionStrings> What might I be doing wrong? Do I need any additional setting(s) to work with version 6.6.4 that wasn't required in the older version 6.4.4?

• How to set up mysql storage for certain rsyslog input matches?

  - by ylluminate

  I'm draining various logs from Heroku to an rsyslog linux (ubuntu) server and am starting to have a little more to bite off than I can chew in terms of working with my log histories. I am needing to be able drill back in time based on more flexible details and more flexible access than what the standard syslog file(s) provide. I'm thinking that logging to mysql may be the correct approach, but how do I set this up such that it pulls only certain log entries into a table based on an identified? For example, I see a long hex string identifying each log entry from a certain Heroku app instance. I assume that I can just pipe those into the mysql socket vs ALL rsyslog input into mysql... Could someone please direct me to a resource that can walk me through the process of setting something like this up or simply provide some details that can help? I have 15+ years of Unix experience so I just need some nudging in the right direction as I've not really done a tremendous amount of work with syslog daemons previously in terms of pooling various servers into one. Additionally, I'd be interested in any log review tools that could make drilling through log arrangements like this more handy for developers.

• 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.

• Using WebDAV for automated downloads

  - by Geo Ego

  I currently manage a number of sites (at one point about a dozen, currently four, but soon growing into the dozens or hundreds) that serve a piece of software to clients at their remote locations. Our web server is Windows SBS Server 2k3, and the remote servers are Windows Server 2k3.When we have new versions of the software, I upload this new software to a specific directory and rename it; each time the clients boot, they pull their software from that specific directory. With just a few sites, it's no problem for me to RDP in and copy the files over. As the number grows, this will quickly become quite unwieldy. So I'm thinking that WebDAV would be part of a solution, so that I could simply push the newest version to our server (Windows SBS Server 2003) and make it available to the sites to grab. However, on the remote server side, what are some suggestions for automating the download? I only want the servers to download the files during downtime (between 3 AM and 9 AM), and I only want them to download if there is a new version available. I had thought of writing a program that checked the files on the WebDAV server at a regular interval, compared a hash of the current software to a hash of the software on the server, and only downloaded if they were different, but I'm wondering if there is something I am unaware of that can automate the process.

• Apache HTTPd FollowSymLinks path permission

  - by apast

  Hi, I'm configuring my development environment with a basic Apache HTTPd configuration. But, to avoid a often problem, I want to map my test URL to my development folder. I'm using Ubuntu. My development path is located under the following example path: /home/myusername/myworkspace/hptargetpath/src/pages Considering the following symbolic link mapping: #ls -l /opt/share/www/mydevelopmentrootpath: lrwxrwxrwx 1 root root 77 2011-02-13 18:53 /opt/share/www/mydevelopmentrootpath -> /home/myusername/myworkspace/hptargetpath/src/pages With this folder mapping, I configured Apache HTTPd with the following configuration: <VirtualHost *:*> ServerName local.server.com ServerAdmin [email protected] DirectoryIndex index.html DocumentRoot /opt/share/www/mydevelopmentrootpath <Directory /opt/share/www/mydevelopmentrootpath/ > Options +Indexes Options +FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> </VirtualHost> But, I'm receiving a 403 Forbidden error when I want to access index.html under the address http://local.server.com/index.html. 403 Forbidden You don't have permission to access /index.html on this server. On httpd debug log, I checked the following message: [Sun Feb 13 19:34:47 2011] [error] [client 127.0.1.1] Symbolic link not allowed or link target not accessible: /opt/share/www/mydevelopmentrootpath I'm thinking that this problem is been generated by some path permission. It's not a direct permission to directory, but some intermediate directory in the path. There's a directive on httpd core Options: SymLinksIfOwnerMatch The server will only follow symbolic links for which the target file or directory is owned by the same user id as the link. But, I tested it without effects. Somebody may help me? I think that it's a trivial configuration on development environment. Best regards, And Past

• DNS failover in a two datacenter scenario

  - by wanson

  I'm trying to implement a low-cost solution for website high availability. I'm looking for the downsides of the following scenario: I have two servers with the same configuration, content, mysql replication (dual-master). They are in different datacenters - let's call them serverA and serverB. Users use serverA - serverB is more like a backup. Now, I want to use DNS failover, to switch users from serverA to serverB when serverA goes down. My idea is that I setup DNS servers (bind/powerdns) on serverA and serverB - let's call them ns1.website.com and ns2.website.com (assuming I own website.com). Then I configure my domain to use them as its nameservers. Both DNS servers will return serverA IP as my website's IP. If serverA goes down I can (either manually or automatically from serverB) change configuration of serverB's DNS, to return IP of serverB as website's IP. Of course the TTL will be low, as it's supposed to be in DNS failovers. I know that it may take some time to switch to serverB (DNS ttl, time to detect serverA failure, serverB DNS reconfiguration etc), and that some small part of users won't use serverB anyway. And I'm OK with that. But what are other downsides of such an approach? An alternative scenario is that ns1.website.com will return serverA IP as website's IP, and ns2.website.com will return serverB IP as website's IP. But AFAIK clients not always use primary nameserver and sometimes would use secondary one. So some small part of users would use serverB instead of serverA which is not quite what I'd like. Can you confirm that DNS clients behave like that and can you tell what percentage of clients would possibly use serverB instead of serverA (statistically)? This one also has the downside that when serverA goes back up, it will be automatically used as website's primary server, which is also a bad situation (cold cache, mysql replication could fail in the meantime etc). So I'm adding it only as a theoretical alternative. I was thinking about using some professional DNS failover companies but they charge for the number of DNS requests and the fees are very high (why?)

• Tridion 2011 SP1 Core Service - expose to live server within PROD env

  - by Neil

  We have a requirement to allow our users to submit information about their "projects" - a small piece of text and single image they upload. Ultimately we'll have a listing page of user contributed projects that others can comment on and rate. We've decided to user Tridion's UGC for rating & comments site-wide for this first phase which has got me thinking - UGC is tied to Tridion published pages & components, if we want UGC on our user-submitted projects, they'll have to be created within Tridion as components themselves, not be sat in some custom db table? Is this where the Core Service could come in? My understanding is that the CD Web Service is for retrieval, not for interacting with the Content Manager. Is it OK (!) architecturally to expose the Core Service only to our live application servers so our backend .NET code can create "project components" that can be then be published by editors allowing them to be commented on? Everything sounds pretty neat and tidy apart from the "exposing Core Service to live servers" bit. Without this though I'd have to write a custom way to "transfer" it back over to the Content Manager - maybe like Audience Manager Sync works? Anyone done this before?

• Most scalable way of serving a small set of static HTTP content

  - by Ekevoo

  The story: Hi guys. I'm among the people responsible for serving the results of the most anticipated (by number of people participating) annual entrance exam in my state. As such, when our results are published, the interest is overwhelming. In the past we delegated the responsibility of serving the results to the media, but that spoils a little the officialness of these results. This year we went with a little (long overdue) experiment of using lighttpd instead of Apache as well as other physical network optimizations I wasn't directly involved with. The results were very satisfactory. The server didn't choke even once, nor we saw any of the usual Twitter complaints on unavailability and/or slowness that were previously common. However, because we still delegated the first publication of the results to the media I'm still not 100% sure we can handle the load of actually publishing the results first. The question: Now because these files are like 14MB in total and a true lightweight Linux distribution isn't that big either, I'm thinking: what if next year we run full RAMdrive? Is there any? Is that useful? Is that worth it for a team that uses Debian almost exclusively? Are there other optimizations that I should be focusing on instead?

• Replacing quotes in a file

  - by Matthijs

  I have a large number of large semicolon-separated data files. All string fields are surrounded by double quotes. In some of the files, there are extra quotes in the string fields, which messes up the subsequent importing of the data for analysis (I'm importing to Stata). This code allows me to see the problematic quotes using gnu-awk: echo '"This";"is";1;"line" of" data";""with";"extra quotes""' | awk 'BEGIN { FPAT = "([^;]+)|(\"[^\"]+\")"}; {for ( i=1 ; i<=NF ; i++ ) if ($i ~ /^"(.*".*)+"$/) {print NR, $i}}' 1 "line" of" data" 1 ""with" 1 "extra quotes"" but I do not know how to replace them. I was thinking of doing the replace manually, but it turns out that there are several hundred matches in some of the files. I know about awk's -sub-, -gsub-, and -match- functions, but I am not sure how to design a search and replace for this specific problem. In the example above, the respective fields should be "This", "is", 1, "line of data", "with", "extra quotes", that is: all semicolons are separators, and all quotes except for the outermost quotes should be removed. Should I may be use -sed-, or is -awk- the right tool? Hope you can help me out! Thanks, Matthijs

• Win7 VM @ ESXi Server @ VMWorkstation (Win7) - ping works only from VM -> HostOS, not vice versa

  - by DK2000

  right now I'm toying around with VM Ware stuff and not having any pcs then my laptop I decided to run an ESXi Server inside of VWmware Workstation. I was just curios to see if the server would allow to setup and run a VM. And after some tweaking there it was, working like a charm. Okay not that fast but startin' the VM from vSphere and "opening a console" gave my direct access to that VM. Now I wanted to see if I could ping the host from the VM (VM Workstation Network is set to "host only"). And it worked, at least from the VM I could ping the ESXi server and the host. From the host I am able to ping the ESXi Server but I can't ping the VM! I asked myself anyway where the VM got its ip adress from. At the DCHPs IP there is at no machine after all. I even tried to use that DHCP adress for my Host and it didn't work out. You can see my settings from the screenshot here (it's pretty wide so just a link): http://yfrog.com/n4desktopfeop The only thing that got me thinking was when I once changed the ESXi's IP from 192.168.92.137 to 192.168.0.137. I still was able to connect to the ESXi server via its new IP but when I tried to run the VM console from vSphere I got an error after a while that said "couldnt connect to 192.168.92.137:903". So vSphere connects just through a port of the ESXi server to the VM?!? Could I setup a Linux VM to use it as a DHCP that I'd at least have control over the IPs that are given. Which lowest end linux could be used for this purpose?!? Thank you for your time! :)

• 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't Install Win2k8 On KVM - Classic 0x80070013 error

  - by javano

  I am trying to install Win2k8 Std as a KVM guest on Debian Squeeze. As you can see from these screen shots; No drives are detected (I have blanked out a 20GB image for testing) - screenshot1 I am using this driver CD: - screenshot2 I have signed the Win7 driver (I assume this was the most appropriate one?) - screenshot3 I can now see an unpartitioned drive - screenshot4 But I can't create a new partition on here, getting the error code 0x80070013 - screenshot5 I have had this error code before but only on a physical server. If I remember correctly it was complaining because the disks were partitioned as GPT (because it was a server that was being re-purposed) so repartitioning with an MS-DOS table fixed that. This is a blank disk image though. What is wrong here, and how can I correct this? Thank you. UPDATE I have booted the VM with a Gparted-Live disk and formatted this volume with an MS-DOS partitioning scheme, and a single 20GB NTFS file system. Now when I boot the Win2k8 CD, load my drivers, I get a different error. As you can see at the bottom of screenshot6 "Windows cannot be installed on this hard drive space. Windows must be installed to a partition formatted as NTFS". Clicking format produces the error (0x80004005) on the screen, so I think this is still a driver issue because Windows can see the drive but not interact with it properly. Is that insane thinking?

• How to play WAV file through Network Paging Interface

  - by BGM

  In our building we have a Viking Paging ZPI-4 Interface for our intercom. The interface receives data from our Asterisk Phone system via a Cisco SPA112 Port Adapter which has it's own IP address on the network and converts digital into analog. Asterisk plays the "5" tone and then allows the user's voice to commence over the connection. Now, what I want to do is to play a wav file over this Viking Paging device using the Cisco Port Adapter. I know how to get Asterisk to do it, but I want to do this without Asterisk. I want some kind of program that can talk to the Cisco Port Adapter and then transmit the wav file into the Viking Paging Device. What kind of program do I need to get or make? Now, I found this link if it helps anyone with ideas. I also found this information, but I'm not sure how to apply it. I also found this, but it involves an arduino. However, I already have the analog-to-digital convertor, and the Viking will handle sending sound over the paging speakers. I just need to know how to send the wav file to the Viking via the Port Adapter. So far, I know my wav file should be formatted as 8bit mono, and I need to send the "5" tone to open the Viking Pager's channel. [update] I am trying to figure out if I can use VLC player to stream to the ipaddress of the Port Adapter. So far I'm not having success with that, and don't even know if it will work. Windows Media Player has a streaming option too. I am thinking that since the Cisco Port Adapter thinks it is a sort of phone, that the only way this can be done is via SIP.

• Loading a big database dump into PostgreSQL using cat

  - by RussH

  I have a pair of very large (~17 GB) database dumps that I want to load into postgresql 9.3. After installing the database packages, learning more or less how to use them, and fiddling around a little on various StackExchange pages (particularly this question), it looks like a proper command for me to use is something like: cat mydb.pgdump | psql mydb because of the format the dump is in. My machine has 16 GB of RAM, and I'm not familiar with the cat command but I do know that my RAM is 99% exhausted and the database is taking a while to load. My machine isn't non-responsive to the point of hanging; I can run other commands in other terminal windows and have them execute at a reasonable clip, but I am wondering if cat is the best way to pipe in the file or if something else is more efficient? My concern is that maybe cat could be using up all the RAM so the database doesn't have much to work with, throttling its performance. But I'm new to thinking about RAM issues like this and don't know if I'm worrying about nothing. Now that I think about it, this seems to be more of a question about cat and its memory usage than anything else. If there is a more appropriate forum for this question please let me know. Thanks!

• Postfix relay all mail through SES except for one sending domain / address

  - by Kevin

  I'm thinking this is really really super simple, but I can't figure out what I need to do. I don't mess with Postfix much (Just let it run and do its thing) so I've got no idea where to even start with this. We have postfix currently configured to relay all mail out through SES using the code below. We need to modify this so that emails sent from one of our domains (domain.com) DO NOT go through SES. Everything else should continue to flow out through the SES connection. I'm assuming this is like a one line thing but my google skills are not helping me at all. relayhost = email-smtp.us-east-1.amazonaws.com:25 smtp_sasl_auth_enable = yes smtp_sasl_security_options = noanonymous smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_use_tls = yes smtp_tls_security_level = encrypt smtp_tls_note_starttls_offer = yes smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt smtp_destination_concurrency_limit = 450 Update I have created sender_transport file in /etc/postfix. In it is @domain.com smtp: I then ran this through postmap and placed sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transport above the above block of code and restarted postfix, but still all email is going out through SES. Log after sending Oct 22 14:38:48 web postfix/smtp[19446]: 4B19D640002: to=<[email protected]>, relay=email-smtp.us-east-1.amazonaws.com[54.243.47.187]:25, delay=1.4, delays=0.01/0/0.92/0.44, dsn=2.0.0, status=sent (250 Ok 00000141e21b181f-ee6f7c4f-f0f5-4b0f-ba69-2db146a4f988-000000) Oct 22 14:38:48 web postfix/qmgr[19435]: 4B19D640002: removed I don't think this log is what you're looking for, but it's the only thing that is logged when mail goes out, and this is with me running /usr/sbin/postfix -v start manually and not with the init script.
