  - by Sparsh Gupta

  I have a nginx server with load balancing and reverse proxy. Right now its behing another nginx but very soon I plan to make it front, where it will receive TCP connections from clients directly at a rate of 500req/second I am having some big troubles with the server. I have pasted my configurations here and I am kinda sure that the problem is with ipconntrac and similar things which are alient to me http://paste.org/pastebin/view/28543 root@load_balancer:/proc/sys/net/ipv4# netstat -an|awk '/tcp/ {print $6}'|sort|uniq -c 67 CLOSING 727 ESTABLISHED 173 FIN_WAIT1 183 FIN_WAIT2 19 LAST_ACK 5 LISTEN 447 SYN_RECV 1 SYN_SENT 27970 TIME_WAIT Its a ubuntu machine with mainly nginx (load balancer and reverse proxy) installed. It surely isnt great. Can you help me understand whats going on and how can I fix it. This is my live server and I am sure its in a bad shape right now. Any document or commands to fix this, or settings I should make to make this better and reduce time wait and fin_wait1/2 better would be awesome.

• Wireless connection switches off IP address

  - by Sanjay Gupta

  I have a Lenovo laptop with windows XP and a wireless connection at home. The wireless connection works when initially I switch on the computer. but if I leave it for even 5 minutes, the wireless is gone. Then I have to shut it off and start computer all over again, waiting for 5 minutes. Even if the wireless speed is 48Mbps or better, it gives the message "Renewing IP address" and gets stuck there not moving to the next stage. Other laptop in the household works fine and can be left on. Why does this happen ? I suspect that IP address is the problem and somehow is not registered in all the necessary files.

• Can I automatically login to ssh using passwords from OS X keychain?

  - by Chaitanya Gupta

  I need to login to an ssh server which doesn't support key based authentication. And I don't want to type the passwords every time. I am using OS X Lion (10.7.2). I have added the passwords to the OS X keychain[1]. Now I can retrieve the password automatically from the keychain using /usr/bin/security, however I can't find a way to send this password to the ssh prompt. I also tried sshpass. However when I try to run it ssh exits with the following error: ssh_askpass: exec(/usr/libexec/ssh-askpass): No such file or directory Permission denied, please try again. ssh_askpass: exec(/usr/libexec/ssh-askpass): No such file or directory Permission denied, please try again. ssh_askpass: exec(/usr/libexec/ssh-askpass): No such file or directory Permission denied (publickey,password). Is there anyway I can login to this server without having to enter the password every time? Notes The scheme I use in keychain looks like this Kind: Internet password Account: username Where: ssh://server-name

• Stop Munin messages from /var/log/syslog

  - by Sparsh Gupta

  Hello I am using munin on a system which is adding a log entry in syslog everytime the munin-node cron job executes. It is not an issue but it sometimes makes other errors spotting difficult. There are entries like Feb 28 07:05:01 li235-57 CRON[2634]: (root) CMD (if [ -x /etc/munin/plugins/apt_all ]; then /etc/munin/plugins/apt_all update 7200 12 >/dev/null; elif [ -x /etc/munin/plugins/apt ]; then /etc/munin/plugins/apt update 7200 12 >/dev/null; fi) every 5 minutes and I was wondering how can I stop the messages going into syslog. For munin specific errors I anyways have to keep an eye on /var/log/munin/* Thanks Sparsh

• Why does Midori on Fedora Linux pretend to be Safari on Mac OS X?

  - by Suhail Gupta

  If you are using Google Chrome on Linux then the User-Agent request header will look like this: Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1 From above we come to know the browser is Chrome and OS is Linux (I guess!). But when I log from the browser Midori using the same OS which is Linux (Fedora) I get to see this: Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-us) AppleWebKit/535+ (KHTML, like Gecko) Version/5.0 Safari/535.4+ Midori/0.4 Why does it say Macintosh?

• Does more heat generation mean more wear and tear?

  - by Suhail Gupta

  I read that hardware generally used on PC is not optimized for running Linux. That is the reason the machine emits large amount of heat and doesn't give the battery back up , that we will get while working on windows. ~REF Does it also mean more wear and tear of the hardware (when using linux as compared when using windows ) ? Note : I have personally experienced large heat emission while working with Fedora 16 and Ubuntu 11.xx on my laptop.

• Munin Aggregate Graphs from several servers

  - by Sparsh Gupta

  I am using DNS round robin load balancing and have divided my total traffic onto multiple servers. Each server does around 300-400req/second but I am interested in having an aggregate graph telling me the TOTAL of all requests per second served by our architecture. Is there any way I can do this. Right now each graph in Munin comes as a separate graph as they depict things on one server. I am using configuration as follow which doesn't work doesnt work for me, does this configuration got errors?

• How to Set up MySQL Server to utilize more memory

  - by Cyril Gupta

  Hi there, I have MySQL setup on Windows along with Plesk. The version is 5.0.45 Community. The databases I have on the server are MyISAM as well as InnoDb, but predominantly innodb. I had 8G memory on my server, but MySQL isn't going up more than 1.3G and tweaking the settings isn't helping. I tried to increase the memory allocation for innodb_buffer_pool_size, it works if I set it up to 1G, but if I set 2G, or above the server doesn't come back online! I want mySQL to use at least 5-6 Gigs of the memory I have for performance, but I can't get this to work. Can anyone please help? My mysql config file is below (there are 2 mysqld sections... when i used MySQL workbench it created another one!)

• nginx hashing on GET parameter

  - by Sparsh Gupta

  I have two Varnish servers and I plan to add more varnish servers. I am using a nginx load balancer to divide traffic to these varnish servers. To utilize maximum RAM of each varnish server, I need that same request reaches same varnish server. Same request can be identified by one GET parameter in the request URL say 'a' In a normal code, I would do something like- (if I need to divide all traffic between 2 Varnish servers) if($arg_a % 2 == 0) { proxy_pass varnish1; } if($arg_a % 2 == 1) { proxy_pass varnish2; } This is basically doing a even / odd check on GET parameter a and then deciding which upstream pool to send the request. My question are- What is the nginx equivalent of such a code. I dont know if nginx accepts modulas Is there a better/ efficient hashing function built in with nginx (0.8.54) which I can possibly use. In future I want to add more upstream pools so I need not to change %2 to %3 %4 and so on Any other alternate way to solve this problem

• nginx errors: upstream timed out (110: Connection timed out)

  - by Sparsh Gupta

  Hi, I have a nginx server with 5 backend servers. We serve around 400-500 requests/second. I have started getting a large number of Upstream Timed out errors (110: Connection timed out) Error string in error.log looks like 2011/01/10 21:59:46 [error] 1153#0: *1699246778 upstream timed out (110: Connection timed out) while reading response header from upstream, client: {IP}, server: {domain}, request: "GET {URL} HTTP/1.1", upstream: "http://{backend_server}:80/{url}", host: "{domain}", referrer: "{referrer}" Any suggestions how to debug such errors. I am unable to find a munin plugin to keep a check on number of upstream errors. Sometime the number of errors per day is way too high and somedays its a more decent 3 digit number. A munin graph would probably help us finding out any pattern or correlation with anything else How can we make the number of such error as ZERO

• Which SSL certificate to buy [closed]

  - by Sparsh Gupta

  I am reading several notes on SSL certificates and comparison. What matters to me the most is speed. I can read that encryption is same with all different certificates available but I was wondering if there is any difference in the performance of the website with different certificates involved. I am ofcourse interested in end to end response times and I wonder if the type of encryption or number of certificates required as Chain Certificates makes a difference in speed. I dont really care for cost but looking for a good SSL certificate which ideally gives me absolutely no pain and best performance. Recommendations?

• Logformat for catching asked hostname in a *.domain.com scenario?

  - by Dhiraj Gupta

  I have an Apache 2.2 VirtualHost with a *.domain.com Servername. This is required for my scenario, all subdomains are handled with the same site. Now, in the access log, I am trying to figure out a logformat variable (or way) that will let me log the asked for domain name. If I use the vhost_combined format, all I get in my access log is *.domain.com entries, not the actual vhost that was asked for. Anyone know how to do this?

• Remote Debugging and deployment of a Project Built Locally

  - by Abhishek Gupta

  We work on our projects locally, and deploy them on remote servers for testing. This is currently done via git commits/push/pulls. But the problem here is that most of the commit contain errors and/or break the code in significant manner due to the lack of testing. Is there a way we can deploy the code on the remote server without using git commits, or some sort of temporary commits or patch or any other mechanism? And only commit, whenever it is important.
