    by Visakh S,

    Junior Guru

    As a company specializing in outsourced support, we keep track of ticket flow trends. A metric that often attracts special attention of web hosts is the volume of tickets generated in non-business-hours. A concern sometimes posted by new web hosts is the necessity of a full 24/7 hosting support. Is it really required? Can't the tickets wait till morning when the staff gets back to office?

    The answer in short is, you DO need a 24/7 hosting support desk, and here is why.

  • The day my Postfix/SASL server refused to deliver mail

    by Paul Fernandez,

    Evangelist

    I encountered this issue one Saturday afternoon, on which I happened to be working. Being a Saturday, I expected a relatively quiet day at the office. This was why, I was initially surprised when our monitoring software reported that there were more than 3500 mails present in one of our servers (say, vm.domain.com) mail queue. Within half an hour, the count had increased to approximately 5000 mails. There goes my quiet Saturday. Sigh.

    Before proceeding, I would like to point out that all our servers run on CentOS and use Postfix.

  • Extend WHMCS : Create Your own WHMCS API Functions

    by Farhath Fathima,

    Evangelist

    WHMCS is an awesome piece of software, and already a hot favorite of web hosting companies. The features it provides are more than sufficient for an average host to run his business. However, the environment of each host is unique in terms of market, vendors, and operation methods. This diversity often calls for customization of the WHMCS installation. For a web host which employs an experienced developer/company, this would be an simple task.

    However, for a company completely new to WHMCS, this can be a conundrum. A common gripe among novice developers is the lack of detailed documentation on create API entensions to WHMCS. With this article I hope to reach out to those hosts who are stuck with a WHMCS API customization issue.

    So, you have configured your server with backup. Thats great!

  • An introduction to cron and its administration from command line interface

    by Visakh S,

    Junior Guru

    A cron job is the first bit of magic a new webmaster would see in a web hosting account. You tell the server to run a script at scheduled times, and it gets done. Updates happen automatically, data gets filled in automatically, and mails get sent right on schedule. Its like you get your personal robo-servant.

    All the modern web hosting control panels like cPanel have beautiful interfaces to add cron jobs as is shown in this WHMCS documentation, and most webmasters will be just happy to use that and be done with it.

    However, if you are one of those technology loving webmasters who dream to own a VPS or a dedicated server at some time, and want to know the internal workings of the cron magic, read on.

  • The curious case of Google tagging all mails as spam

    by Visakh S,

    Junior Guru

    Gmail is one of the most reliable and reputable mail services. So it piqued our tech team when our billing division reported that Google seemed to think our server is a spam source.

    We routinely keep track of all spam black lists, and were quite sure that the server reputation was not affected. The mails that were sent to other major providers like Yahoo, Hotmail, etc were not affected. Only Google was sending all our mails to the spam folder.

    The email header analysis

    OK. So, it could be because of the recent HTML changes in the invoice, right? We needed to test that, and sent a plain text mail to our Gmail account. It still landed in the spam box. Hmm..

    It was time for a more methodical analysis of mail headers.

  • Fun at Bobcares - With Merry Berries, every day is a day to celebrate!

    by Visakh S,

    Junior Guru

    The time was 7:30 am. All was set. Everyone at the front desk waited with bated breath. It wont be long now, and I should make my move.

    Right on schedule, the sunshine yellow Tata Nano pulled up, and Agni stepped out for his tightly packed schedule at office. All usual smiles and hellos greeted him. He didnt notice a couple of suppressed giggles at the front desk, which were promptly put down by a smack over the heads from their co-workers.

    Agni looked rushed. He seemed pre-occupied and distracted. Perfect! Probably didnt get time for his break fast either.

    OK, its time!

    Even in this age of high configuration servers and cloud instances, server load spikes are all too common. Getting the approach right is half the work done in troubleshooting a high server load.

    In our earlier posts we covered the basics of server load, how you can monitor the server for server load here & here, and how you can improve your site loading speed. We had also posted on a very targeted load mitigation approach for cPanel servers.

    Today, I will guide you on how to approach a high load situation in a linux server. This approach is a part of our internal knowledge base which is used as part of our server optimization service.
