    I manage a file sharing website (like mediafire,hotFile, etc.) and there is a problem when people try to download from one of the servers.It goes like this: I have one main server - there I have the mysql database and the website himself, and I have more servers to host the files.The download process goes like this: user get a link to the outside server. This page connect remotely to the main server and make querys with the database. After the querys, the download get started.Now, all of the downloads works fine, except from one of the servers. The weirdest thing is that sometimes the download from this server is works, and sometimes not!It&quot;s about 70% of times the download from the problematic server is works, and 30% of times the download isn&quot;t works.When the download isn&quot;t working the error message is:Connect failed: Lost connection to MySQL server at &quot;reading authorization packet&quot;, system error: 0The my.cnf looks like this:[mysqld]skip-name-resolvebulk_insert_buffer_size = 8Mconcurrent_insert = 2connect_timeout = 10default-storage-engine = MyISAMinnodb_buffer_pool_size=16Minteractive_timeout = 35join_buffer_size = 2Mkey_buffer_size = 192Mlocal-infile=0log-error=/var/log/mysql/error.loglog-slow-querieslog-slow-queries=/var/log/mysql/mysql-slow.loglong_query_time=1max_allowed_packet = 32Mmax_connections = 3000max_heap_table_size = 256Mmax_user_connections= 400max_write_lock_count = 8myisam_max_sort_file_size = 256Mmyisam_sort_buffer_size = 64Mopen_files_limit=128Kquery_alloc_block_size = 65536query_cache_limit = 16Mquery_cache_size = 128Mquery_cache_type = 1query_prealloc_size = 262144range_alloc_block_size = 4096read_buffer_size = 2Mread_rnd_buffer_size = 1Msort_buffer_size = 2Mtable_cache = 48Kthread_cache_size = 512tmp_table_size = 256Mtransaction_alloc_block_size = 4096transaction_prealloc_size = 4096wait_timeout = 100max_connect_errors = 5000[mysqld_safe]log-error=/var/log/mysqld.logpid-file=/var/run/mysqld/mysqld.pidHow can I fix the problem?

    We are a small UK based IT services company and need remote help on an hourly basis with our VMWare platform. We run a modest datacentre for a few of our clients and need someone to assist us remotely with the maintenance and housekeeping of our VMWare services. We anticipate engaging someone to provide regular remote maintenance on a scheduled basis, as well as attending to ad hoc requests for system changes. We are comfortable with you working out of UK office hours if you have other commitments, but you need to appreciate that some requests will require a same day solution.We hope to develop a long term relationship with our chosen contractor.Thanks for your interest.

    We have one dedicated server running centos 6 with WHM /cpanel and a few accounts on it. We have just purchased another server in a different data center that we plan on setting up with centos and WHM. We want to &quot;connect&quot; the two servers so they share name servers and accounts can be moved between them. We know WHM supports something like this, and that&quot;s simply what we want to put in place. We need a knowledgeable individual who is experienced in WHM to consult with us to set this up. We prefer communication by Skype. Thanks!

    Hi everyone,I need to get an open source application compiled for OS X 10.6 and above. 3.0.5 should be used.It is a stable and well tested command line tool, open source, implemented in C++ with a cool makefile etc. However, developers do not provide binaries for 10.6, just for 10.9.For what I understand it is feasable and fairly easy: is basically just a matter of using brew and some patience to get the makefile of the application to work without errors...The resulting binary should be stand-alone (all static linking if possible) and work in 10.6 and above. I will send you a test file to run the program. First 1/2 payment will be released if you show me a screenshot with the result. Next 1/2 when I get the binary and test it myself.This shouldn&quot;t be hard, I will need it as soon as possible.Thanks!

    HI,I will hand over Root access to a Linode 4GB VPS. My live Magento sites are NOT hosted on this VPS server currently so you will need to do a local PC Host file edit to view and test Magento on this VPS.My Magento install is clean, no bad plugins (and is pretty fast on a Nexcess shared server). The VPS you will work on is a standard LAMP set-up, Magento is a little slow on it and the LAMP set-up needs to be Optimised.I don&quot;t want any Full Page Cache set-up, but I want Apache. PHP and MySQL Optimised. PHP-FPM would be good, maybe Nginx in front of Apache, APC and Memcache, Redis Cache, Percona Server... (BUT I WILL TRUST YOUR ADVICE)I am NOT looking for a over complexed set-up. THIS BIT IS IMPORTANT. I DON&quot;T WANT SOMEONE TO GOOGLE HOW DO IT THIS WORK, I NEED A PRO LINUX / MAGENTO SERVER EXPERT WHO HAS DONE THIS KIND OF WORK BEFORE MANY TIMES AND I&quot;M LOOK FOR A SIGNIFICANT IMPROVEMENT IN THE MAGENTO BACKEND AND FRONTEND WHICH IS A LITTLE SLOW.I WOULD LIKE THIS WORK DONE ASAP.
