List of threads of people's dead iDRAC's:........

pulseaudio issue on QEMU/KVM guest VM when microphone is replugged/unplugged pulseaudio: pa_threaded_mainloop_lock failed pulseaudio: Reason: Invalid argument

postfix/dovecot Sent emails missing sometimes

On occassion and from a variety of networks and clients, Sent messages don't get saved. I'm wondering if these log messages could be why: May 3 14:16:39 mail.box postfix/smtpd[5195]: connect from 192.168.1.58 May 3 14:16:39 mail.box postfix/smtpd[5195]: SSL_accept error from 192.168.1.58: -1 May 3 14:16:39 mail.box postfix/smtpd[5195]: lost connection after CONNECT from 192.168.1.58 May 3 14:16:39 mail.box postfix/smtpd[5195]:........

MySQL Authentication fails after Upgrade to Version 5.5

ERROR 1045 (28000): Access denied for user 'contentmanager'@'localhost' (using password: YES) For fun I thought I'd reset the password: GRANT ALL ON thecontent.* TO contentmanager IDENTIFIED by 'dfdfsdfdsfsdfsd'; ERROR 1470 (HY000): String 'contentmanager' is too long for user name (should be no longer than 16) This is ridiculous that this new version has some bizarre 16 character username limit and not only that but i........

pcnet32: eth0: transmit timed out, status 97fb, resetting - NIC card problem solution

I've encountered this problem before and I believe it may affect other drivers (I could test but I don't have time). This was happening on my custom Linux system with the pcnet32 driver. pcnet32: eth0: transmit timed out, status 97fb, resetting (and some other kernel module tracing in dmesg) Basically it means the card is connected (it shows connected in full duplex etc.. and recognized if the cable is disconnected too) but no packets can be sent or received........

The Importance of a High Quality Power Supply/Power Supplies To Prevent Overheating/System Crash/Hardware Damage

For years I've always built cheap systems believing that there is little difference in more expensive components when it comes to reliability and quality, I generally believe this still except for Power Supplies. I've always bought cheap cases with nice sounding 350-550W stock/cheap/crap power supplies and haven't had any issues for the most part until recently. One such case is an NGEAR case with a 550W Optimax power supply, I always read that these supplies don't produce the........

How To Test If Your Hard Drive Is Good/Signs of dying hard drive

I like dd, although it only reads it, usually a read test of the entire disk will uncover if your hard drive is bad in some parts. This is a good thing to do at least once a month, a lot of times bizarre program behavior, laginess and crashing/unnmounting problems etc.. are due to a failing disc and SMART won't know it or indicate a problem: We must also remember there's never a guarantee, I've found that ever since we moved to larger and more platters per drive with 1TB drives........

mdadm RAID 1 adventures

I separated the 2 drives in the RAID 1 array. 1 is the old one /dev/sda and is out of date, while the separated other one /dev/sdc was in another drive and mounted and used with more data (updated). I wonder how mdadm will handle this: usb-storage: device scan complete md: md127 stopped. md: bind md: md127: raid array is not clean -- starting background reconstruction raid1: raid set md127 active with 1 out of 2 m........

MySQL Recover/Reset Lost/Forgotten root Password

One note is to secure MySQL, I don't know for sure but I believe you could login to MySQL remotely with no password during this operation (I'm not sure, maybe it doesn't accept blank passwords but I firewall MySQL port anyway and recommend you do the same). First edit /etc/my.cf Under the [mysqld] field add the following line somewhere: skip-grant-tables Now restart mysql: service mysql restart or on Debian sty........

Gigabyte GA-H57M-USB3 Complaint Review/Comments

I'm not impressed with this motherboard, I was impressed with my Gigabyte AM3 board which seems to work flawlessly. Everyone knows that the firmware is flawed, even though I have the F6, it still seems that the system doesn't reset properly or quickly enough. Another HUGE problem is that in most Linux kernels the NIC won't work (if you try 10 times by rebooting it might). I also notice that you need to power down for it to work. This board does not seem very com........

rsync ERROR: sdb2/backup.r18 failed verification -- update retained.

ERROR: sdb2/backup.r18 failed verification -- update retained. This happened when Iwas rsyncing a dying hard drive, a lot of people seem to report this as an error with rsync itself but I don't think rsync is the issue at all. I know the source hard drive was bad, it was having all kinds of timeout, seek, hardware ECC recovered and reset errors. The only time something else could be the problem is if the data is being corrupted in transit, perhaps through........

Linux AHCI Hotswap Tips - Remember To Reread The Partition Table WITHOUT rebooting

From the package "parted" you can use the command "partprobe" to re-read the partition table. I really hate rebooting, and that's what Iloved to hear about AHCI motherboards, that they allow hotswap so you don't have to reboot. But that's only as good as the OS, if the OS does not reload the partition table you won't be able to do anything with that new drive you attached without rebooting. Yes, even without re-reading the partiton table Linux will........

iPhone Enable Tethering Manually Update ipcc Carrier Settings/Update via SSH

Everyone says there is a "manual" way of doing it and then they tell you to use iTunes, but if you're like me, you're travelling on business in a foreign country and your laptop does not have iTunes and you don't have a way of getting it and/or don't want it. For this example I'm using the provider "du" in Dubai, UAE (United Arab Emirates) but this method works for virtually all providers. The requirements in this case to truly "manually update........
