• Amazon EC2: Instances, IPs and a wordpress blog (LAMP)

  - by JustinXXVII

  I had a link to my blog posted on Reddit yesterday and MySQL crashed on my EC2 Micro instance. I know I didn't have that many visitors because I used a marketing link that tracks hits. The link got 167 hits over the course of the last 18 hours, and MySQL crashed twice. So anyway, 167 visits is not a lot, so I've done some short term optimizations like restricting the number of Apache threads to limit the MySQL calls. I also set up WP Super Cache to serve static content. Soon I'm going to offload all of my images to S3 or CloudFront. So this leads me to my question. If this doesn't seem to help, and if i have another traffic "spike", how do AMIs work when you have a MySQL database? I think I understand that if you have more than one instance and assign the same Elastic IP to both of them, the incoming traffic gets distributed among both. But what happens when the MySQL database gets updated on one of the instances? I just need to wrap my mind around what happens when I create an AMI and then launch a new instance to help with traffic. Thanks for your suggestions.

• Attach BCC to all emails processed through Windows Server 2008 SMTP relay

  - by Grant H.

  I currently have a relatively complicated application that sends emails via a nightly job through an SMTP server on Windows Server 2008. Is there a way to configure IIS/SMTP to send a copy of every email that's relayed to another email address? Essentially, can I add a BCC on the fly through IIS/SMTP configuration? Because of the complexity of the application, we would prefer to change the behavior this way if it's possible as opposed to making code changes to the application.

• Wordpress network admin pointing to root as opposed to subdirectory

  - by Ian

  I've installed Wordpress on my nginx server in /blogs and new networks will be in /blogs/blogname. All my main site links point to example.com/blogs, but when I go to network admin the links point to http://www.example.com/wp-admin/network/ instead of http://www.example.com/blogs/wp-admin/network/ Here's the multisite section in my config: define('MULTISITE', true); define('SUBDOMAIN_INSTALL', false); $base = '/blogs'; define('DOMAIN_CURRENT_SITE', 'www.example.com'); define('PATH_CURRENT_SITE', '/'); define('SITE_ID_CURRENT_SITE', 1); define('BLOG_ID_CURRENT_SITE', 1); If I try changing PATH_CURRENT_SITE to /blogs, I get a db connection error. Thanks.

• DKIM sign any outgoing mail as the same domain. is possibly?

  - by Felipe Alcacibar

  I have a website, and the users recommend via email to another persons, so the mail come from my site, but I need to appear the user as sender, but "via" mydomain. The logically and what lists management software and companies do is differ the "MAIL FROM" SMTP command and the "From" header (like mailchimp, for example). So I want to DKIM sign a mail with mydomain.com, even if the From header says another domain. is possibly this? I am using postfix with Debian GNU/Linux, and in this case using dkim-filter and dk-filter.

• Lots of files being used by blank web page. What are they?

  - by byronyasgur

  I am trying to optimise a website and I was using the network waterfall facility in Google Chrome. When I looked at the results there were lots of files which I didnt recognise. I first thought they might be something to do with Google Chrome itself, so I put a blank HTML file on my desktop and checked but there was nothing in the waterfall except the file itself. So I put a blank file on my server and I got the output below. What are all these files, are they all necessary, is this normal and do I need to be in any way concerned. My hosting provider has always been excellent in every regard that I'm aware of. My host is shared hosting, using cpanel and is based on a LAMP server. I also note that a couple of those file have problems but I have no idea how to fault find that or whether it's a concern. EDIT: I have cleared the cache so I don't think it's a browser cache issue.

• How can I make outbound requests from two servers that appear to come from the same IP address

  - by Brad

  I am making calls from an ec2 instance to a third party web service (over which I have no control). I would like to be able to scale horizontally, so that I can make these calls from multiple ec2 instances, but the web service I'm calling whitelists my IP, and for the sake of discussion let's assume I can't get another IP address whitelisted. How can I send requests from 2+ machines that appear to the web service to be from the same IP address? Thanks!

• Can Octopussy use messages other than syslog style?

  - by Lee Lowder

  I am currently exploring different options for a centralized log server. We use both Linux (Ubuntu 10.04 / 12.04, LTS for both) and Windows, though for this specific issue only Linux is relevant. I like the interface that octopussy has and it's feature list, but I am hesitant due to a few things. One of the biggest concerns I have is that it seems to be syslog only. The end goal is to have a centralized place for our devs and admins to be able to search through the logs generated by Apache, Tomcat and 70+ web apps spread out among a cluster, for both our prod and test environments. While I did see that octopussy has support for plugins, I haven't been able to find any sort of plugin repo or in depth guides as to what can be done with them. Does anyone know if plugins can be used to allow octopussy to non-syslog messages? Specifically log4j type log messages that may include multi-line stack traces and such. Also, is there a user community for this software, such as a mailing list or forum? I've been unable to locate any so far. Thank you.

• Automated Syslog Error Solution Finder

  - by Dru

  Any automated syslog solution finding frameworks? I want my central syslog server to email a list of problems, their severity and suggested solutions. There have been several questions about centralising system logs and alternative log analysis systems, but I don't get the impression that any of them help with issue resolution. A little background: At work I am now literally doing the work of two people, and both jobs have expanded beyond their initial frameworks. It is not so bad as I have helpers, but they are little more than smart monkeys. While one of my predecessors [I have two, that is how I know I have the jobs of two people] set-up logwatch to email its results out, my monkeys don't have the skills necessary to identify unimportant data. This has caused all of them, and myself sadly, to setup email filters and ignore the whole thing until something goes "bang". It would be handy to have someone else tell them what is important, what is connected, and to suggest a few ways to resolve the issue (I could train then to research the solution first, ha!). My reading of the Splunk and Octopussy sites indicates that I still need to bring my own highly trained monkey to the party. Which I am several years from having.

• DNS Name lookup (was SSH) Not Working After Snow Leopard Upgrade

  - by Peter Cardona

  I think this started with the Snow Leopard update. Cleaned out the .ssh directory, still having the issue. ~: uname -a Darwin california-example-com.local 10.0.0 Darwin Kernel Version 10.0.0: Fri Jul 31 22:47:34 PDT 2009; root:xnu-1456.1.25~1/RELEASE_I386 i386 ~: ssh -V OpenSSH_5.2p1, OpenSSL 0.9.8k 25 Mar 2009 ~: ls -l ~/.ssh ~: nslookup nevada Server: 10.94.62.3 Address: 10.94.62.3#53 Name: nevada.example.com Address: 10.94.62.3 ~: ssh nevada ssh: Could not resolve hostname nevada: nodename nor servname provided, or not known

• Linux monitor logs and email alerts?

  - by Physikal

  I have a server with a faulty power button that likes to reboot itself. Usually there are warning signs, like the acpid log file in /var/log starts spamming garbage for about 10hrs or so. Is there an easy way I can have something monitor the acpid log and email me when it has new activity? I wouldn't consider myself extremely advanced so any "guides" you may have for accomplishing something like this would be very helpful and much appreciated. Thank you!

• Log transport and aggregation at scale

  - by markdrayton

  How're you analysing log files from UNIX/Linux machines? We run several hundred servers which all generate their own log files, either directly or through syslog. I'm looking for a decent solution to aggregate these and pick out important events. This problem breaks down into 3 components: 1) Message transport The classic way is to use syslog to log messages to a remote host. This works fine for applications that log into syslog but less useful for apps that write to a local file. Solutions for this might include having the application log into a FIFO connected to a program to send the message using syslog, or by writing something that will grep the local files and send the output to the central syslog host. However, if we go to the trouble of writing tools to get messages into syslog would we be better replacing the whole lot with something like Facebook's Scribe which offers more flexibility and reliability than syslog? 2) Message aggregation Log entries seem to fall into one of two types: per-host and per-service. Per-host messages are those which occur on one machine; think disk failures or suspicious logins. Per-service messages occur on most or all of the hosts running a service. For instance, we want to know when Apache finds an SSI error but we don't want the same error from 100 machines. In all cases we only want to see one of each type of message: we don't want 10 messages saying the same disk has failed, and we don't want a message each time a broken SSI is hit. One approach to solving this is to aggregate multiple messages of the same type into one on each host, send the messages to a central server and then aggregate messages of the same kind into one overall event. SER can do this but it's awkward to use. Even after a couple of days of fiddling I had only rudimentary aggregations working and had to constantly look up the logic SER uses to correlate events. It's powerful but tricky stuff: I need something which my colleagues can pick up and use in the shortest possible time. SER rules don't meet that requirement. 3) Generating alerts How do we tell our admins when something interesting happens? Mail the group inbox? Inject into Nagios? So, how're you solving this problem? I don't expect an answer on a plate; I can work out the details myself but some high-level discussion on what is surely a common problem would be great. At the moment we're using a mishmash of cron jobs, syslog and who knows what else to find events. This isn't extensible, maintainable or flexible and as such we miss a lot of stuff we shouldn't. Updated: we're already using Nagios for monitoring which is great for detected down hosts/testing services/etc but less useful for scraping log files. I know there are log plugins for Nagios but I'm interested in something more scalable and hierarchical than per-host alerts.

• Converting videos to AVI with AVIDemux for compatibility

  - by Synetech

  I am trying to convert a couple of short videos to AVI (XviD) using AVIDemux. I find that while the resulting videos play fine in VLC, they do not play in an XviD DVD player (nor presumably Xbox 360, PS3, etc.). In fact, they do not even show in Windows Explorer (that is, Explorer cannot read their metadata or display thumbnails). I tried using all three of the AVI Muxer Output Format options, but none worked. Does anyone know what settings to use to produce compatible AVIs with AVIDemux? (I found an old thread where someone complained about AVIs not working on Xbox, but that was a few years ago from an older version.)

• How to download batch of randomly named files

  - by TheLearner

  I need to download a bunch of files from a website but I don't want to have to click on each file to add it to downloadall or whatever. The structure of the website is as follows: http://something.com/katalog/?get=Exclusive/group1/2012.09.03/ The directory has loads of randomly named files with .doc extensions. I can't use the batch feature because the files don't start or end with the same characters e.g. 001...100. Any ideas/

• Outlook.com Sweep rule vs Filter rule

  - by Mahesha999

  New outlook.com introduced new sweep option. With it, you can create a filter to move messages from particular sender to a particular folder after certain days the mail comes. This rules gets added to the Filter list. However we cannot edit this rule by clicking Edit in front of it in that list. The dialog appears saying you should delete the rule and create the new one. I don't understand why sweep rules are considered differently from Filter rules? I have 68 filter rules. What if I want to add such time clause to these filter rules so that instead of moving the incoming mails immediately to a certain folder, they will be kept in Inbox for say 10 days and then they will be moved. Such time clause cannot be added to the filter rules. So should I delete all these 68 filters and create new Sweep rules?

• Email client supporting multiple accounts

  - by TGP1994

  I've been using Microsoft Outlook for a very long time, although one thing that has bugged me is how multiple email accounts are handled. As far as I can tell, there isn't a set and straightforward way of managing multiple accounts in one instance of outlook. For example, when I create an email, saving it as a draft will by default dump it into the first personal folder that I have open, which in my current case, is not where I want it. I would like all trash, spam, drafts, contacts, etc. etc. to be handled on a PF by PF basis. Now to my question: Is there a way to accomplish the task of email account "segregation" in Outlook (2007 is my current version), or is there another client that handles this in a more organized fashion? Note: I don't use most of the features in outlook (I hardly even need special formatting for my messages), I generally just send and read mail, and get a few attachments, so leaving Outlook wouldn't be too much of a stretch for me.

• Crashes and freezes after fixing "BOOTMGR is missing" error

  - by Greg-J

  I came back from a 3-day weekend to a computer that was off. I leave my PC on 24/7, so this was odd. Turn it on to get the dreaded "BOOTMGR is missing" screen. Two attempts at Windows Recovery and it booted into Windows fine. After an hour or so, I get a frozen Chrome and my start bar disappears. Ctrl+Alt+Del brings up an error box telling me that Ctrl+Alt+Del failed to work properly. Clicking on any open application triggers an error (I can't recall the error now, but it essentially just said that the application couldn't be found running or something along those lines). I restart, and again, the same thing happens after a while of use. I turn it on, install the 47 updates I have or so, and then restart it. After a while of use (under an hour), it just freezes completely. My thoughts are: SSDs, RAM or PS. My system specs below: (RAID0) 2 x Crucial M4 CT128M4SSD2 2.5" 128GB SATA III MLC Internal Solid State Drive (SSD) CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CML16GX3M4A1600C9 CORSAIR HX Series HX750 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active 1 x ASUS Maximus IV Gene-Z/GEN3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard 1 x Hitachi GST Deskstar 7K1000.C 0F10383 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive 1 x Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 1 x SAPPHIRE 21197-00-40G Radeon HD 7970 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card 1 x Noctua NH-D14 120mm & 140mm SSO CPU Cooler This is all crammed in a pretty small case (NZXT Vulcan) and has been running perfectly problem-free since January. The only thing out of the ordinary is that there is a fan in the case that is now making noise whereas the case has previously been completely silent. I have no reason to believe this is anything more then correlation, but felt it is worth mentioning. I believe it MAY be the SSDs simply because of the BOOTMGR error, but not sure how to test that theory. My belief that it may be the RAM is simply from experience with frozen machines. I haven't had the time to memtest it, but will. The PS being the culprit is something I've picked up by reading similar threads on various forums, and it seems plausible. I am unsure how to test this though. ANY insight whatsover would be greatly appreciated!

• Created new account instead of alias for original ID

  - by Mahesha999

  Hi I had Live ID for many years. To try Outlook.com I created a new ID. However now I want to use that same ID as an alias in my original Live account, which is also now upgraded to new Outlook Experience. When I went creating alias for that ID, it obviously showed message saying ID is in use. So I searched if I can delete an account altogether. But did not found anyway to delete that newly created account. Then I renamed my newly created ID. It got renamed, but that old ID is now made alias in that new account. So, still I am not able to create an alias with the same ID in my original Live account. What can I do?

• I keep getting a Java incoming connections pop up

  - by 1.21 gigawatts

  I keep getting the following message, "Do you want the application “java” to accept incoming network connections?" First of all, what application? Second, if it's part of the browser, which sometimes the browser isn't open, it doesn't show me what page is requesting it. "Application" is very generic. Third what does that mean? Is it asking if anyone on the internet can make connections to my computer?

• Is there a way to measure wifi traffic on a network from a client?

  - by millimoose

  Is there some way (preferrably one that comes with an existing tool) to measure the traffic going through the whole WiFi network from a computer connected to it? (That is, not from the AP or something between the modem and AP.) My situation is this: a few months back, the internet connection at my parent's place got really sluggish and laggy. (Lag spikes that cause page loads to time out etc, connections plain getting lost and dropping packets forever.) It's impossible to get mom's husband to do anything about this because he brushes this off with something like "just tell your sister to turn off torrents". Unfortunately the WiFi router's firmware doesn't do traffic logging. I'm not going to risk bricking it to put WRT on it; nor am I keen on rewiring the network to add a proxy to analyse the traffic. (I'm one of those people that make computers break just by looking at them, except machines I own.) I'd like to be able to find out roughly how much data is going over the air here while all the LAN wires are out of the router, all the computers accused of torrenting are off, etc. The idea is to either show that: Even if everything but my macbook is turned off, something is congesting the network. The husband is a systems developer and has a whole lot of mysterious hardware that's not to be touched around, one of them might be culprit. There is barely any traffic on the network, but the internet is still sluggish. Meaning this is likely a problem the ISP should solve. (Some hardware of theirs being glitchy, someone on an aggregated line hogging it constantly...) The network is encrypted, but I can temporarily set it to open for the sake of finding this out. So, in conclusion? Can this be done? Or is there some alternative way I could try to diagnose the problem?

• Failing Seagate HDD - Not Recognised

  - by thefragileomen

  I am having a look at a friend's computer which contains a 500GB Seagate HDD. Unfortunately the HDD is not recognised by the BIOS menu and it beeps 11 times upon powerup. I've moved the HDD to another laptop but the problem remains. I've downloaded SeaTools for DOS (Seagate's Diagnostic tool) but unfortunately to no avail and the disc remains unseen when using this DOS boot disc. The HDD is only 6 months old so I'm very surprised at this but it appears a common problem with Seagate 2.5" HDDs as well as other HDDs manufactured by Seagate. I intend to try it in an external caddy on Thursday when back in work and also through a forensic writeblocker but just wondering if anyone has any other suggestions? I am of the opinion it is some chip on the HDD board which prevents it spinning due to a fault. If so, I've lost to deactivate this just so I can simply recover the data on the drive and start with a new disc. Thanks

• mystery Internet traffic to port 445

  - by Ben Collver

  Recently, I noticed traffic from the office network to TCP port 445 on the Internet [a]. Below are the Linux firewall log entries to Facebook's network [b] and Google's network [c]. I would like to identify the source of this traffic. My first guess is that Facebook and Google might be using multiple TCP ports for SSL load balancing. However, I could not confirm this based on the web proxy logs. What else might it be?

• How to get a "live screenshot" in windows

  - by alexei7

  Quick question – do you know any software or way of doing a live screenshot of a window and bring it to the foreground? It’d be like picture link in Excel... My problem is that I am running various tasks in IE and Oracle, and they take forever but i have no way of seeing if they’re done without tabbing back into them all the time. I want something so that I can always see in the foreground the status bar/egg-timers thingy for them. Thanks all

• My microphone is too quiet (seems to be connected with Skype)

  - by AmitM9S6

  I've been chatting with skype for a long time.. and I don't know why, but for X time it's fine, and then it's too quiet.. Here how it goes : I'm booting the PC - getting into a skype call with friends - talking with friends on skype - (everything goes well) - Closing the skype call - Going back to a skype call like a hour after -. They can't hear me well, I have to shout so they'll hear me, and in the settings, it's on 100% + 30 DECIBELS, so I can't raise it higher... and if I'll re-boot my PC, it'll be well until I'll close the skype call again.. Every time I'm skyping with friends well, and then when I close the call and come back after a while, they hear me really low(volume).. I've been trying to fix this problem for about 2 months! If you'll be able to help me, I'd be so happy. (btw It's connected not through USB, but through a microphone connection and headphone connection...) Also, I got Windows 7..

• A server which uses 2 IPs and is needed to give service (under NAT)

  - by user6004

  I have an internal server, which uses a certain service. This service listens on a port, and speaks on a different port. The problem with the service is that it can't listen and speak on the same IP address, so I have configured 2 IP addresses for that NIC, and so I "solved" the problem with the listening and speaking. I have a problem though... I need that server to be NATed, with a public IP address, and that server needs to be available from the outside (and as only one IP)... The question is, how do I solve the situation here? If I do a NAT for one IP address (the listening port), then he will be able to get requests from the outside, but won't be able to send out traffic (because the other IP won't have NAT). If I do NAT on both of the IPs, then when traffic comes in for the listening port, it won't necessarily arrive to the listening IP, but rather to the speaking one. I hope I made myself clear and that there is a sensible solution here that I am missing.

• How to install TortoiseHG on Ubuntu

  - by Webnet

  I just downloaded and installed the latest Ubuntu and it doesn't look like I'm used to. I don't see any Mercurial developer tools in the Ubuntu Software Center. I got on http://tortoisehg.bitbucket.org/download/index.html and it looks like it can be done, but I'm not entirely sure how. I've done some Googling but the results I keep running into are on older versions of Ubuntu. Any ideas on how I can make this happen?
