Announcements / PHP upgraded to 7.2
« on: February 25, 2018, 10:48:27 am »
PHP 5.6 is approaching its end of life, and is no longer receiving regular updates from upstream. That means it's time to move on to the next version, which is PHP 7 (6 was experimental and doesn't count.) I've updated the server to PHP 7.2, and if you're using older PHP software, you may notice errors appearing on your site. If you see messages about mysql (specifically mysql_connect being an "undefined function") then there's a temporary workaround you can add. In any PHP file you need to still use the old MySQL functions, you can add this line right at the start of the PHP section (just after the <?php tag ideally):

Code: [Select]
include_once("mysql-shim.php");
Ideally, if you didn't write the code, you should just update to a newer version that supports php 7 and not use this. But until this, this workaround might help. If you have other problems (or notice errors on any of the main xepher.net pages) please let me know. My own code is using this shim, as it's ANCIENT, and I don't have the patience to rewrite it quite yet.

Announcements / Update Your WordPress Installs!
« on: January 03, 2018, 10:30:49 am »
:UPDATE:
Just as everyone seems to have finally been updated, Wordpress goes and breaks their auto-update process.

https://wordpress.org/news/2018/02/wordpress-4-9-4-maintenance-release/

Everyone (in the world) needs to update manually and then make sure auto-updates are enabled again!


----
Over the New Year we had an account compromised (almost certainly through a MILDLY out of date WordPress install) and it was used to attack other servers, leading to a warning from my VM provider.

Going forward, I'm going to be requiring that all WordPress installs be maintained and kept up to date. To enforce this, I've written a scanner that will automatically find and check the version of any WP installs, and it will be emailing me any time someone is out of date. If you have WP on your site, please go update it NOW to at least version 4.9.1.

As WP is a very popular target, even an install a week out of date can be vulnerable, and so I will be disabling accounts if/when that happens. I've already disabled several, and sent emails of warning to many others. If your account was one that was disabled, email me, and I can release it and allow you to update things. Also, please make sure your offsite contact email is kept up to date so that I can contact you in cases like this. Too many times I have to resort to disabling accounts to get the owners attention, and I'd prefer to avoid that.

Sorry to have to be so strict about this, but with the potential to leverage this server to attack remote targets, the threat is serious enough that I have no choice. If you have any questions or thoughts though, feel free to ask below, or contact me directly if you prefer.

Thank you all for understanding!

Announcements / Major Email Changes
« on: March 11, 2016, 05:36:52 am »
So, spam hit again, and I'm moving to a new mail server. As such, it required a lot of work to reconfigure from the old system. I think I've got most things back to working, but if you have trouble with email here, please let me know. The most likely remaining problems are related to people with custom email domains hosted here.

If you're using your own email client, you need to use SMTP authentication with STARTTLS on port 587 (the "submission" port) to send mail now.

Also note, as email is what's being weird, please feel free to post here on the forums if you're having problems.

EDIT: Your ~/.esmtprc file should look something like this now:

identity = user@xepher.net
        hostname = mail.xepher.net:587
        username = "user"
        password = "mypass"
        starttls = enabled

Announcements / Yesterday's Downtime (2015-09-21)
« on: September 22, 2015, 11:20:26 am »
Many services were offline yesterday, between about 8am and 3pm Pacific Daylight Time. Everything should be fixed now.

The cause was a filesystem glitch that caused one of the disks to behave like it was out of space, even when it should've had many gigabytes to spare. This prevented MySQL from running properly, which meant eventually DNS went down, and also caused problems for mail delivery (as new messages couldn't be created in home directories.)

It should all be fixed now, but if you encounter more problems, please let me know.

My apologies for the downtime.

Announcements / I'll be camping August 11th-15th
« on: August 11, 2014, 06:41:08 am »
Going camping up in Washington's Olympic National Park tomorrow. I'll be offline through Friday, so my apologies if there are any troubles or help needed during that time.

Announcements / New Server
« on: May 29, 2014, 09:53:31 am »
Move is complete... at least as far as I can tell. This was a completely new installation on a new, virtual server, with all data migrated by hand. I apologize for the two hours or so of interruptions overnight, but I think most things are working now. I'm sure I'll have overlooked something though, so please let me know if you run into any problems. Email was especially irksome, so it may be best if you post below, just in case it's still wonky.

With the new server, I noticed a lot of spam was being sent via automated wordpress and other things. Apparently at some point I upgraded something and forgot to lock the email back down as I had in the past. I've done that again now, so if you're having errors with your PHP scripts being unable to send mail, you may not have a properly configured .esmtprc file. See this post for details: http://xepher.net/forum/index.php?topic=626.msg6855#msg6855

Also, you will get warnings about the SSH server key having changed. This is expected as it's a new server. Likewise, the cert for SSL email (imap/smtp) and https has changed as well. This is self signed and will generate warnings. This is expected, but obviously don't trust my server with your credit card info and stuff. :-)

Announcements / Xepher.net Is Moving Again
« on: May 14, 2014, 07:08:32 pm »
So it's been several years since the last server move. In that time, the current datacenter has been bought out twice. Originally, it was "The Planet" then "Softlayer" and now it belongs to IBM. In all that time, hosting prices have come down and bandwidth has gone up, so in the next few days or so, I'm planning to migrate to a new host. I think I can squeeze us into a Linode VPS that will save me $85/month. On paper it should be faster and better in all respects except disk space. I'm going to poke at it for a bit though, and see how it holds up.

When the migration finally happens, it should be "transparent" to end users. Site owners may find themselves locked out for a few hours while a final file sync is done, and MySQL will likely be put in read-only mode for the final few minutes of transfer. I'll try to do all this in off hours as much as possible of course.

I'll post another announcement when things are done, and then you can all yell at me about the things I screwed up or forgot. :-)

Announcements / Forum Oops
« on: January 24, 2014, 05:53:24 am »
I somehow left the forum in maintenance mode for a while here. My apologies to anyone that was unable to access things. It should be back to normal functionality now though. Please let me know if you run into any problems though.

Announcements / Minor software upgrades
« on: August 30, 2013, 03:32:12 am »
PHP, Apache, and MySQL (along with a few dozen supporting libraries and such) have been updated. All of these were minor version updates, so shouldn't impact much, but if you run into problems, as always, just let me know.

In the not too distant future -- that is, a few weeks from now -- I will probably be upgrading PHP from 5.4 to 5.5. As far as I know, this shouldn't be too big of an upgrade, but you might want to make sure your PHP scripts and applications are compatible with PHP 5.5.

Announcements / Equilibrium
« on: July 17, 2013, 06:56:01 am »
So I'm now comfortably settled in Bend, Oregon. I've two different internet feeds (I'm a nerd) and more free time than I know what to do with. If anyone is journeying near this part of the country and would like to say hi, I've got a spare bed to offer. Otherwise, know that all things are on cruise control as far as the site is concerned. I'm spending my time getting in shape, doing some mountain biking, hiking, etc. and I'm toying with Aruduino and the other electronics, as well as nerding it up in some local RPG groups and Belegarth (which is hitting people with padding sticks and calling them swords.) :-)

Announcements / Freedom!
« on: May 06, 2013, 07:53:22 am »
So, I quit my job on friday, and my lease here in Houston is up on the 18th. After that, I'm packing everything I own in a trailer and driving northwest. My goal is Bend, Oregon. I have no job, no place to live, and know absolutely no one for hundreds of miles in any direction. My only plan is to "chill the buck out" for several months and try to find something more interesting to do with my life than sit behind a desk.

How will this affect the site? Well, it shouldn't. I've plenty of money saved up, and the server bills are on auto-pay. Theoretically, I shouldn't need another job for two to three years. Only possible impact is if something technically mucks up while I'm in transit, I might not catch it for a bit longer. I will have a laptop with me and random wifi along the way though.

That said, I don't plan to work for at least another six months, maybe longer. I'm going to travel, relax, and enjoy things. To that end, if anyone is situated between here (Houston) and Oregon, and would like to have a pint of beer or a cup of coffee, let me know. This road trip may be solo, but it should still be epic, and I'd love to meet any of ya'll I can along the way. :-P

Announcements / Upgrades to forum and webmail
« on: April 04, 2013, 07:25:43 pm »
I've upgraded both the forum and webmail software to new versions. The webmail one went smoothly, but I hit some bumps with the forums. I think I got it sorted out, but if you run into problems, please let me know.

Announcements / Mail delivery problems
« on: November 24, 2012, 07:59:52 pm »
Over the past two days, /var filled up, preventing new email messages from being accepted by the server here. I've corrected the problem, and as messages queued on other servers are retried, they should start trickling in here shortly. If you normally have a decent volume of mail to your account here, some of it may come in big chunks now that things are back online. I apologize for the interruption in service, as I should have caught that earlier but I've been busy with the holidays.

As to the root cause, it was the apache error log filling up very quickly with deprecated and strict code warnings. Even though these are disabled in the default config, several users appear to have code the explicitly turns some of this extra logging back on, and thus fills up the log faster than usual. If you have a site here, now would be a good time to see if it's generating errors and update any third-party scripts you have installed to ones compatible with php 5.4. Not a big deal at this point though, I'm just going to rotate the error log more frequently.

Announcements / Upgraded to PHP 5.4
« on: October 15, 2012, 02:22:47 am »
The server has been upgraded to PHP 5.4.6 (from 5.3.15) and other minor software bits were upgraded as well. As usual, if you run into problems, please let me know.

Announcements / I'll be off line for the next week
« on: September 30, 2012, 06:06:50 am »
I'm going on a cruise this week, and won't have any form of internet access until I return on the 7th of October. As such, please don't be offended if I don't respond to email or other issues until then. :-)

Edit: Back now, all good!
