• What is causing random hard freezes on my system? Kaspersky?

  - by Christian Ivicevic

  The last few weeks I experienced a new strange behavior of my computer. Sometimes Windows 7 just freezes with no real reason at all. While listening to music for example the playback hangs and you can hear a very nasty sound. Neither mouse nor keyboard input is handled and everything is just stuck. Using Ubuntu this does not happen, so I think it is just a matter of driver issues or a Windows 7 bug. Furthermore I am really suspicious about Kaspersky (Internet Security 11) and so I let it perform a complete virus scan while no other app is running. At about 50% it happened again and I needed to restart the computer by holding the power button the bad way... A really weird thing is that playing Skyrim this happened once, however music playback did not stop. Only the framerate dropped to 0 and sometimes for a few seconds I am able to move. Therefore I am really confused as furthermore no bluescreen pops up. Memtest told me that everything seems to be alright... Can anyone explain me which data you need about my hardware and software (and which tools tools to use to gather the informatik) to be able to provide any help on my problem?

• PHP Suhosin extension is not loading

  - by wintercounter

  For some reason i have to adjust the suhosin.request.max_vars and suhosin.post.max_vars directives. I'm using ispCP, and it has default the suhosin patch, but as i read, i need to install the extension too. I've did this with apt-get install php5-suhosin and the suhosin.ini appeared in conf.d, and suhosin.so exists too in /usr/lib/php5. After the Apache restart the extension isn't loading. phpinfo() says: Scan this dir for additional .ini files /etc/php5/cgi/conf.d additional .ini files parsed /etc/php5/cgi/conf.d/adodb.ini, /etc/php5/cgi/conf.d/curl.ini, /etc/php5/cgi/conf.d/eAccelerator.ini, /etc/php5/cgi/conf.d/gd.ini, /etc/php5/cgi/conf.d/idn.ini, /etc/php5/cgi/conf.d/imagick.ini, /etc/php5/cgi/conf.d/imap.ini, /etc/php5/cgi/conf.d/mcrypt.ini, /etc/php5/cgi/conf.d/memcache.ini, /etc/php5/cgi/conf.d/mhash.ini, /etc/php5/cgi/conf.d/ming.ini, /etc/php5/cgi/conf.d/mysql.ini, /etc/php5/cgi/conf.d/mysqli.ini, /etc/php5/cgi/conf.d/pdo.ini, /etc/php5/cgi/conf.d/pdo_mysql.ini, /etc/php5/cgi/conf.d/pdo_sqlite.ini, /etc/php5/cgi/conf.d/ps.ini, /etc/php5/cgi/conf.d/pspell.ini, /etc/php5/cgi/conf.d/recode.ini, /etc/php5/cgi/conf.d/snmp.ini, /etc/php5/cgi/conf.d/sqlite.ini, /etc/php5/cgi/conf.d/tidy.ini, /etc/php5/cgi/conf.d/xmlrpc.ini, /etc/php5/cgi/conf.d/xsl.ini As you can see, it doesn't loads the suhosin.ini. What can be the problem?

• nmap on my webserver shows TCP ports 554 and 7070 open

  - by atc

  I have a webserver that hosts various websites for me. The two services that are accessible outside are SSH and Apache2. These are running on a non-standard and standard port, respectively. All other ports are closed explicitly via arno-iptables-firewall. The host is running Debian Testing. I noticed that a scan of the host using nmap produced different results from different PCs. From my laptop on my home network (behind a BT Homehub), I get the following: Not shown: 996 filtered ports PORT STATE SERVICE 80/tcp open http 554/tcp open rtsp 7070/tcp open realserver 9000/tcp open cslistener whereas scanning from a US-based server with nmap 5.00 and a Linux box in Norway running nmap 5.21 I get the following: Not shown: 998 filtered ports PORT STATE SERVICE 80/tcp open http 9000/tcp open cslistener so I hope it's my internal network or ISP that's playing up, but I cannot be sure. Running a netstat -l | grep 7070 produces nothing. Similarly for port 554. Can anyone explain the peculiarities I'm seeing?

• mdadm cron job sends email that cron has run

  - by Andrew

  I've got an Ubuntu 8.04 server using mdadm to create several RAID1 arrays. I created /etc/cron.hourly/mdadm as follows: #! /bin/sh set -e mdadm --monitor /dev/md0 /dev/md3 /dev/md4 --oneshot (Yes, the array numbers are not sequential, and I'm not using --scan beacuse I have a degraded array that may or may not have been used as swap and I can't delete, but I think that's a separate issue. If it's the underlying cause of this, I need to fix it.) mdadm sends me email (configured in the /etc/mdadm/mdadm.conf) on DegradedArray etc. events. This is the desired behaviour. What is not desired, and I can't work out, is why cron is sending me (relatively pointless) emails, via an alias in /etc/aliases: From: root@<hostname> (Cron Daemon) To: root@<hostname> Subject: Cron <root@<hostname>> cd / && run-parts --report /etc/cron.hourly Content-Type: text/plain; charset=ANSI_X3.4-1968 X-Cron-Env: <SHELL=/bin/sh> X-Cron-Env: <PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin> X-Cron-Env: <HOME=/root> X-Cron-Env: <LOGNAME=root> Message-Id: <id@hostname> Date: Fri, 7 May 2010 13:17:01 +0930 (CST) /etc/cron.hourly/mdadm: mdadm: Monitor using email address "<root_alias@domain>" from config file I've got a dozen other servers behaving correctly (mdadm sends email, cron doesnt') with identical /etc/crontab files: # /etc/crontab: system-wide crontab # <snip comments> SHELL=/bin/sh PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin # m h dom mon dow user command 17 * * * * root cd / && run-parts --report /etc/cron.hourly <snip anacron jobs> Should I simply remove the --report, or is there something else in my cron config somewhere causing this?

• rr.com appended to URL and I don't know why

  - by Steph

  I've been having some pretty bad and intermittent internet connectivity issues. I keep getting timeouts on my browsers, or what appears to be timeouts on my browsers. In Chrome it's generally error 21. FF it times out. And so on. While this is happening, I can go into the command line and ping or traceroute the same domain and it works fine. I use my cellphone on the same network and it's fine connecting to the same domain. And when it fails, it's all domains that are down in all browsers, chrome, FF, etc. I also noticed that when I try to connect to 192.168.1.1 it says in chrome did you mean www.192.168.1.1rr.com but when I enter https://192.168.1.1 it's fine. It only seems to do this in Chrome. This is making me think I have a virus. I did some researching about something called road runner, but I can't find any related traces. I also ran a full virus scan using nod32 (eset) and nothing. Any suggestion or help would be greatly appreciated. The intermittent loss of total internet access is really annoying and I'm worried about why it's trying to append the rr.com domain in Chrome. I suspect I'm dealing with two different issues, but you never know. Also for the DNS I'm using Google's DNS servers, the famous 8.8.8.8 and 8.8.8.4

• Debugging UI Problems in IE8 (Was IE8 on Windows 7 Authentication Mess)

  - by alharaka

  UPDATE: I think the real question I need to ask here is: how does a technician debug UI problems with Internet Explorer, and not HTML rendering issues that have pretty good tools? I am aware of the SysInternals tools and others mentioned below, but maybe I am not harnessing their power properly. Someone else in the TechNet forum I mentioned had a similar issue. Again, I have lots of data, I am not sure how to properly interpret it. ORIGINAL POST: So I tried the venerable Technet Forums to solve this isse. In short, the Windows Security dialog has no place to put credentials, rendering pretty much useless. This happens to apply for a whole bunch of our intranet websites, and only a select number of users with a few laptops have this problem. It ends up looking like this. Things I have tried so far: Disabling local Group Policy (not domain connected) Disabling local Security Policy Resetting IE settings A few system restores Re-registering a bunch of IE DLL's and all other steps here Reinstalling IE8 (dism /online /disable-feature /featurename:"internet-explorer-optional-x86, reboot, dism /online /enable-feature /featurename:"internet-explorer-optional-x86, and reboot) And SFC scan, which found nothing Still, nothing. Not only am I fed up, but I have begun to really work with APIExplorer and Procmon as mentioned in the Technet original because I want to know WHAT is happening, not just fix it. Any thoughts?

• Can a wifi AP act as a client, and a server at the same time?

  - by nbolton

  I feel this is SF worthy (as opposed to SU) as I go into a bit of detail on gateways/routing. Here's my ideal setup (if possible) -- there is a wifi network (lets call it bob's) with which I want access to, but I have a few other computers on my network which I want to keep behind a firewall. So I was thinking of buying a wireless access point so that I could set it up to connect to bob's network from the AP, and then from my server, connect to the AP via ethernet. So that's the first bit. Second part is that I want to have my own private wifi network off the back of this; can I then tell the AP to serve a new network called foobar. When I say private network, I mean that my server is actually a Debian linux install with routing configured (and I also do some QoS stuff on, etc). So ideally, I'd like all the clients on the private network to be behind the server in terms of routing. However, if the private clients connect to the server via wifi, then aren't they exposed to the "public" network? That is, if someone is savvy enough to scan for my IP range. Also, to do routing I'd need to connect two ethernet cables between the server and the AP (because you can't do routing/QoS on virtual devices) -- which isn't a problem really; but I'm not sure whether the AP will allow me to separate the public and private LANs. Or, as well as the AP, am I better getting a wifi-to-ethernet adapter for the server? I could use a wifi usb, but this can be tricky to set up on headless linux; plus the signal strength is a bit lousy. If this question is a bit vague/spurious in places, please comment and I will explain in more detail.

• Is it possible to extract contents of a ThinApp container?

  - by rsk82

  Is there possible to extract such packages made by somebody else. Ok, so if there is no general way of extracting such archives, which can be a huge exe file or tiny exe starter with huge packed *.bin file with main files of an app that is to be run in portable way - is there a way to set an option in compilation *.ini file or other way to make such package able to be extracted. I remember I read somewhere that somebody created a tiny program (in was mentioned in vmware forums as far as I can remember, it was a crude thing coded for private use and I never managed to download it) to sit with main portable application and if such application has an open/save file dialog, it is possible to navigate to that program which virtually sits in the program files alongside main app from within the main app, and such program would scan all files that it can see and somehow is able to distiguish a real file from virtual one, and save all virtual files in a structure that is similar to the initial compilation folder from which portable app was created. I know that it is a very round-about way of doing things, but maybe the only one feasible. Nevertheless any news on this front ? Do antiviruses can somehow unpack these things ? Maybe they must buy a code or license for it from VmWare ? Edit: I found http://communities.vmware.com/thread/257433?tstart=600 and still trying to make sense out of this. Wrong, this was about moving old version of thinapp to win7.

• Can't remotely connect through SQL Server Management Studio

  - by FAtBalloon

  I have setup a SQL Server 2008 Express instance on a dedicated Windows 2008 Server hosted by 1and1.com. I cannot connect remotely to the server through management studio. I have taken the following steps below and am beyond any further ideas. I have researched the site and cannot figure anything else out so please forgive me if I missed something obvious, but I'm going crazy. Here's the lowdown. The SQL Server instance is running and works perfectly when working locally. In SQL Server Management Studio, I have checked the box "Allow Remote Connections to this Server" I have removed any external hardware firewall settings from the 1and1 admin panel Windows firewall on the server has been disabled, but just for kicks I added an inbound rule that allows for all connections on port 1433. In SQL Native Client configuration, TCP/IP is enabled. I also made sure the "IP1" with the server's IP address had a 0 for dynamic port, but I deleted it and added 1433 in the regular TCP Port field. I also set the "IPALL" TCP Port to 1433. In SQL Native Client configuration, SQL Server Browser is also running and I also tried adding an ALIAS in the I restarted SQL server after I set this value. Doing a "netstat -ano" on the server machine returns a TCP 0.0.0.0:1433 LISTENING UDP 0.0.0.0:1434 LISTENING I do a port scan from my local computer and it says that the port is FILTERED instead of LISTENING. I also tried to connect from Management studio on my local machine and it is throwing a connection error. Tried the following server names with SQL Server and Windows Authentication marked in the database security. ipaddress\SQLEXPRESS,1433 ipaddress\SQLEXPRESS ipaddress ipaddress,1433 tcp:ipaddress\SQLEXPRESS tcp:ipaddress\SQLEXPRESS,1433

• ZFS - Impact of L2ARC cache device failure (Nexenta)

  - by ewwhite

  I have an HP ProLiant DL380 G7 server running as a NexentaStor storage unit. The server has 36GB RAM, 2 LSI 9211-8i SAS controllers (no SAS expanders), 2 SAS system drives, 12 SAS data drives, a hot-spare disk, an Intel X25-M L2ARC cache and a DDRdrive PCI ZIL accelerator. This system serves NFS to multiple VMWare hosts. I also have about 90-100GB of deduplicated data on the array. I've had two incidents where performance tanked suddenly, leaving the VM guests and Nexenta SSH/Web consoles inaccessible and requiring a full reboot of the array to restore functionality. In both cases, it was the Intel X-25M L2ARC SSD that failed or was "offlined". NexentaStor failed to alert me on the cache failure, however the general ZFS FMA alert was visible on the (unresponsive) console screen. The zpool status output showed: pool: vol1 state: ONLINE scan: scrub repaired 0 in 0h57m with 0 errors on Sat May 21 05:57:27 2011 config: NAME STATE READ WRITE CKSUM vol1 ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c8t5000C50031B94409d0 ONLINE 0 0 0 c9t5000C50031BBFE25d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c10t5000C50031D158FDd0 ONLINE 0 0 0 c11t5000C5002C823045d0 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 c12t5000C50031D91AD1d0 ONLINE 0 0 0 c2t5000C50031D911B9d0 ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 c13t5000C50031BC293Dd0 ONLINE 0 0 0 c14t5000C50031BD208Dd0 ONLINE 0 0 0 mirror-4 ONLINE 0 0 0 c15t5000C50031BBF6F5d0 ONLINE 0 0 0 c16t5000C50031D8CFADd0 ONLINE 0 0 0 mirror-5 ONLINE 0 0 0 c17t5000C50031BC0E01d0 ONLINE 0 0 0 c18t5000C5002C7CCE41d0 ONLINE 0 0 0 logs c19t0d0 ONLINE 0 0 0 cache c6t5001517959467B45d0 FAULTED 2 542 0 too many errors spares c7t5000C50031CB43D9d0 AVAIL errors: No known data errors This did not trigger any alerts from within Nexenta. I was under the impression that an L2ARC failure would not impact the system. But in this case, it surely was the culprit. I've never seen any recommendations to RAID L2ARC. Removing the bad SSD entirely from the server got me back running, but I'm concerned about the impact of the device failure (and maybe the lack of notification from NexentaStor as well). Edit - What's the current best-choice SSD for L2ARC cache applications these days?

• Random Hard Freeze of Windows 7 (is Kaspersky to be blamed for this?)

  - by Christian Ivicevic

  The last few weeks I experienced a new strange behavior of my computer. Sometimes Windows 7 just freezes with no real reason at all. While listening to music for example the playback hangs and you can hear a very nasty sound. Neither mouse nor keyboard input is handled and everything is just stuck.

• Apache doesn't immediately notice a change in the document root

  - by Tom

  We use capistrano for website deployments and our Apache document root is a symlink to a particular code release. The deployment procedure switches the symlink from the old release to the new release as the final step of the deployment. We are migrating our webservers from real servers running RHEL 5.6 to Amazon EC2 virtual machines running Ubuntu 11.10 and the new servers are suffering from a problem where Apache doesn't immediately notice the change to it's document root when the symlink is switched. It can take a second or so (and I think I've even seen it take a couple of minutes). It's kind of like Apache has cached the physical path of the symlink for some time. Does anyone know some Apache settings I could look at to get it to "scan" for changes to it's served files quicker. Thoughts: I read that the disks on virtual machines are much slower (since they are network attached storage). Perhaps the filesystem cache somehow works differently too? If so, is there anything that can be done? The website runs PHP code. Perhaps there is some PHP config differences between RHEL and Ubuntu? I checked realpath_cache_ttl but both servers have it commented out: e.g. ; Duration of time, in seconds for which to cache realpath information for a given ; file or directory. For systems with rarely changing files, consider increasing this ; value. ; http://www.php.net/manual/en/ini.core.php#ini.realpath-cache-ttl ;realpath_cache_ttl = 120 We do use the APC opcode cache but don't think it's the issue due to experimentation. The PHP code is in different file paths for each deployment and we ensure stat=1. Here is a similar question that is very interesting: 294107 - but doesn't provide an answer for me. One solution would be to reload Apache everytime we modify the document root symlink. I'll do this if we can't find another solution.

• On a failing hard drive, I am able to view data but unable to copy it - why?

  - by Tom

  I have a 2.5" external hard drive that is failing. It's not making the expected 'clicking' noise that most hard drives and I am able to view the data, but I am unable to actually retrieve the data. I attempted to use SpinRite in order to access the data on the drive, but it didn't like the external drive. When I view the drive's property page, the drive shows that it's used space is at 100% and that it has 0 bytes available; however, the progress indicator under the drive icon in Windows Explorer shows that it's roughly 50% full (which is correct). When I attempt to run Windows' "Error Checking" tool and attempt to "scan for an attempt recovery of bad sectors," the tool begins to run then immediately closes with no error message. I am able to browse the contents of the drive using Windows Explorer. When I begin to try copying any given single file, the copy process begins, an indicator starts, and then the copy fails with no real error message. The Disk Management page in Computer Management under Control Panel also shows this drive has being 'Healthy.' I dropped the drive off at a data recovery store and they said that "The data seems to be intact, but an internal failure is preventing any information from being retrieved." They offered to provide me references to a data recovery specialist. I've also attempted to run CHKDSK on the drive (with and without arguments) but it returns the following error: The type of the filesystem is RAW. CHKDSK is not available for RAW drives. Before going the route of more expensive data recovery, I'm wondering if these symptoms sound familiar to anyone? Other questions... I'm willing to continue trying tools such as TestDisk and/or PhotoRec (as the majority of the data that I'd like to salvage are photos) but how long I should expect either tool to run given approximately 400GB of data? I'm also comfortable using Linux so I welcome any suggestions for utilities or tools and strategies with which you've had success.

• Outlook express 6 crashes after "synchonizing account"

  - by Ira Baxter

  [EDIT: Revised OE version to match reality] I use Outlook Express (OE) 6.00.3790.3959 to read newsgroups. I regularly scan through about 100 newsgroups. When I select a newsgroup, and then select "synchronize account", OE goes through the newsgroups visibly updating the unread message count. It gets apparantly to the end, and then comes back to check for Watched Conversations, of which I typically have a few scattered across the newsgroups. It invariably crashes with some kind of access fault. A dialog box pops up saying "Want to debug with "; I invariable say No, and the process goes away. I restart OE, select the newsgroup, and skip "Synchronize Account"; I am able to read news and everything seems just fine. This behavior has occurred since I set it up several months ago. Is the newsgroups database screwed up? Can I run something like CHKDSK or Outlooks PST repair to fix things up? Any suggestions as to what to do? The system is Windows XP 64 system installed in January 2008. I accept Windows Updates and install them on a regular basis. I use Outlook (not OE) for regular email an it behaves perfectly normally.

• Handheld Linux device can't see one wireless network

  - by Nathan

  I'm using a Nokia N810 running OS 2008 (version 5.2008.43-7; should be the latest). It can see networks up and down the street in my neighborhood and can connect to mine using WEP. I can also connect to free networks at restaurants and the like. When I bring it into work, it can't see a wireless network ("No connections available"). When I use netstumbler on my laptop I can see a list of several essids showing green connectivity for the network. I know that the network has its essid broadcast, and I know that it's unsecured. When I run iwlist wlan0 scan, I see several APs with no essid, but I don't see anything with an essid set. I have verified using iwlist that my hardware supports the correct channels and speeds. I know this isn't a Nokia/mobile forum, but it's running what's basically a Debian kernel. Any suggestions on what to do in this case? I'm really frustrated by this. Thanks, Nathan

• Hard drive failed, suspected filesystem corruption, still cannot salvage any data from harddrive

  - by Hippy-Head

  Firstly, I am terribly sorry if this is a duplicate, but I couldn't find a similar issue to mine, so here goes. I have a 1TB hdd bought around 8 months ago used as backup hard drive. I have not used the drive for a period of time whatsoever, and when I was trying to get back to some files on it, it was completely wiped just like that. At first it would not boot I tried everything from command line chkdsk and filesystem recovery software to rebuilt it. After a few attempts I managed to initialize it, at that time it was an achievement. The problems started when I tried to recover the data inside, I have used A LOT of software free and commercial software on both Mac and Windows, with the help of cmd or Terminal commands, however no data of any kind was recovered, even after leaving it thoroughly scan for around 9-10 hours all night sometimes longer, with no results at all. I am somewhat desperate, I am usually good at retrieving data from corrupt hard drives, but this is not the case. Call me paranoid, but I do not want to give it to someone to fix it for me, as I have a lot of photos and personal stuff that I do not want anyone to see.

• Fixing corrupt files or corrupt file table on a USB drive?

  - by Kelsey

  I was doing a virus scan on an external USB drive while copying data over to it. While AVG was scanning my system got locked up I think due to the USB drive running out of space and it required a reboot. Since that time all data on the external drive is no longer accessible. I can see all the files in the root and directories but I cannot browse into any of them as Windows 7 gives an error stating they are corrupt. I think the file table or whatever it uses to store the index of what exists on the drive has been corrupted since it still shows the the drive as being almost full but everything I do a properties check on says it is 0 bytes. Does anyone know how to 'unlock' or recover this data? Is there a way to rebuild the file table somehow? Luckily I can recover this data from other sources as a last resort but I would like to fix this if possible. Any help would be appreciated. Thanks.

• Desktop.ini Issues/Confusion

  - by EpicDavi

  BACKSTORY: I was out of town for a while and I forgot to turn my computer off. When I came back I saw that a desktop.ini file was on my desktop (using Windows 7). I thought that was odd because I knew it was a system file and it usually didn't show up due to the fact that I had disable the feature to show system files. Also it wasn't translucent like the other system files. I went to my control panel and saw that the "Hide protected operating system files" was indeed enabled. This puzzled me so I disabled the setting and another one was on my desktop like it usually is hidden. So now I have to desktop.ini files on my desktop: one hidden and one not hidden. I am doing an antivirus check to see if anything was going on and I will give an update soon. I am pretty sure these files are harmless and could be deleted but I would rather get another person's opinion on the subject. Thanks! UPDATE: I did an anti-virus scan and it seems I have no problems. It is odd because the file seems to maintain system file properties such as not being able to be edited and other things. Also I have tried restarting my computer and it is still not hidden. So the question remains: What should I do with the file and what caused it?

• How does the LeftHand SAN perform in a Production environment?

  - by Keith Sirmons

  Howdy, I previously asked this ServerFault question: Does anyone have experience with lefthands VSA SAN The general consensus looks like it does not perform well enough for a production SQL server even at a light load. So the new question is, How does LeftHand's SAN perform on the HP or Dell dedicated Hardware boxes? We are looking at the Starter SAN with 2 HP nodes in a 2-way replication, 2 ESX servers hosting a total of 2 Active Directory server, 1 MS SQL server, 1 File Server, and 1 General Purpose Server for things like Virus Scan (All Microsoft Server 2005 or 2008). The reason I am looking at LeftHand is for the complete software package. I plan to have a DR site and like how the SAN can perform an Async Replication to the offsite location without having to go back to the Vendor for more licenses. I also like the redundancy built into the Network Raid architecture. I have looked at other SANS and found different faults with them. For example, Dell's EqualLogic: Found that although the individual box is very redundant in hardware, the Data once spanned across multiple boxes is not redundant, if a node goes down you have lost the only copy of the data sitting on that hardware (One thing is certain, all hardware fails... When? is the only question.). I have used an XioTech SAN as well.. Well worth the money BTW, but I think it is overkill for the size of the office I am targeting. The cost to get the hardware redundancy in the XioTech makes it a little out of reach for the budget I am working in. Thank you, Keith

• Setting up SSL for phpMyAdmin

  - by Ubuntu User

  I would like to run phpmyadmin using my SSL certificate. I read that if I placed the following within the file: /etc/phpmyadmin/config.inc.php, it would force it to use SSL. And now it does... $cfg['ForceSSL'] =true; However, my issue is when I did this, now I get an error stating "cannot connect to server." I do a port scan and my port 443 is closed for one, but I am connecting via https:// for my secure web based email admin panel. This tells me this may not be the issue. Second, is that I have a SSL certificate I purchased but I am not sure how to apply this cert. mydomain.com.crt is sitting on my desktop, how should I be utilizing this? I remember creating a self signed cert for my web-email access. Do I have to do this for phpmyadmin as well? At least this way, since I am the only one who will ever access the DB, it will never expire. Also the phpmyadmin used to come up as: http://mydomain/phpmyadmin/ of course I am now trying to get to https://mydomain.com/phpmyadmin/ however, I do not have any pages on my website that requires https:// currently. In the future I may add this. But for now, I only want to access phpmyadmin via ssl. I can use my own -- but if this causes problems with future ecommerce apps under mydomain.com I would rather use the SSL cert I already purchased. Thank you!
