• Mac: window manager frozen, have ssh access

  - by Bernd

  I have a Mac which regularly runs into a problem. The user interface stops reponding, showing a "frozen" user interface. The mouse is still moving but clicking does not trigger anything. This happens about once a week. Solution so far is to force switch-off the Mac and reboot it. I have ssh root access to the Mac. Killing (kill -9) the active application has no visible impact on what is shown on the screen. Any ideas on how to diagnose this? Is there a way to restart the window manager from the ssh shell? Killing /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Resources/WindowServer seems not to be possible. The Mac is an early 2008 iMac and runs Lion with latest updates. /Library/Logs/DiagnosticReports is empty. Update: Problem stays after update to Mountain Lion. The WindowServer process is in "uninterruptible wait" state ("U" flag in ps output set): imac:~ root# ps ax|awk "NR==1|| /WindowServer/"|grep -v awk PID TT STAT TIME COMMAND 86 ?? Us 50:51.69 /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Resources/WindowServer -daemon Any idea for diagnosing what blocks the process? Any idea for "waking up" the process?

• Integrated Graphics went kaput, can I switch to dedicated graphics if I can't get into the BIOS

  - by Om Nom Nom

  I have an 8 year old computer (Pentium 4 1.6 GHz, 256 MB DDR RAM) which is not turning on (it beeps for 10 seconds and then goes off). Nothing appears on the screen, so I can't get into the BIOS. A computer repair person listened to the beeping pattern and told me that its because of the integrated graphics on the motherboard is defective. It's an ASUS P4S333-VM motherboard and the graphics solution is SiS 650. He tried putting in a PCI graphics card expecting that the computer will use that instead and ignore the integrated graphics, but apparently older computers don't switch automatically to the dedicated graphics card; it needs to be changed from the BIOS. But, I can't get inside the BIOS settings as I already said. I am told that the only option now is to replace the motherboard (which is not feasible since it's very old now). So, is there any way to make the computer use the PCI graphics card? IIRC, the motherboard also has an AGP port, but I think that it will also need to be selected from the BIOS?

• OpenSwan (IPSEC) on Fedora 13 with Snow Leopard as a client

  - by sicn

  I recently installed OpenSwan on my Fedora 13 machine. I want to use it to connect with Mac OS X with L2TP over IPSEC, unfortunately I am already stuck on the IPSEC-negotation part. My server is running behind a NATted firewall so my external IP differs from the server's IP. The server has a fixed IP on the network and the same is almost always valid for the clients (they are usually behind a NATted firewall). I installed OpenSwan on Fedora 13 and have following configuration: config setup protostack=netkey nat_traversal=yes virtual_private=%v4:10.0.0.0/8,%v4:192.168.0.0/16,%v4:172.16.0.0/12 oe=off nhelpers=0 conn L2TP-PSK-NAT rightsubnet=vhost:%priv also=L2TP-PSK-noNAT conn L2TP-PSK-noNAT authby=secret pfs=no auto=add keyingtries=3 rekey=no ikelifetime=8h keylife=1h type=transport left=my.servers.external.ip leftprotoport=17/1701 right=%any rightprotoport=17/0 IPSEC starts fine and listens to UDP 500 and 4500. These two ports are opened in the firewall and are forwarded fine to the server. In my /etc/ipsec.secrets file I have my.servers.external.ip %any: "LongAndDifficultPassword" And finally in my sysctl.conf (the redirect-entries are there because OpenSwan was strongly protesting about send/accept_redirects being active) I have net.ipv4.ip_forward = 1 net.ipv4.conf.all.send_redirects = 0 net.ipv4.conf.all.accept_redirects = 0 Running "ipsec verify" gives me "all greens" (except Opportunistic Encryption Support, which is DISABLED), however, when trying to connect my Mac gives me following in the logs: Nov 1 19:30:28 macbook pppd[4904]: pppd 2.4.2 (Apple version 412.3) started by user, uid 1011 Nov 1 19:30:28 macbook pppd[4904]: L2TP connecting to server 'my.servers.ip.address' (my.servers.ip.address)...

• Converting DisplayPort and/or HDMI to DVI-D?

  - by Jeff Atwood

  Newer Radeon video cards come with four ports standard: DVI (x2) HDMI DisplayPort If I want to run three 24" monitors, all of which are DVI only, from this video card -- is it possible to convert either the HDMI or DisplayPort to DVI? If so, how? And which one is easier/cheaper to convert? I did a little research and it looks like there isn't a simple "dongle" method. I found this DisplayPort to DVI-D Dual Link Adapter but it's $120; almost cheaper to buy a new monitor that supports HDMI or DisplayPort inputs at that point! There's also a HDMI to DVI-D adapter at Monoprice but I'm not sure it will work, either. AnandTech seems to imply that you do need the DisplayPort-to-DVI: The only catch to this specific port layout is that the card still only has enough TMDS transmitters for two ports. So you can use 2x DVI or 1x DVI + HDMI, but not 2x DVI + HDMI. For 3 DVI-derived ports, you will need an active DisplayPort-to-DVI adapter.

• X11 performance problem after upgrading from Centos3 to Centos5 with an ATI Rage XL

  - by Marcelo Santos

  After upgrading a computer from Centos3 to Centos5 an application that does a lot of scrolling took a very high performance hit. top tells me that X is using a lot of CPU and that was not happening before. The machine has an ATI Rage XL with 8MB and X is using the ati driver as there is no proprietary ATI driver for this board on linux.

• Ubuntu lucid, maverick high iowait

  - by netom

  I'm using Ubuntu, and I've got the same problem with Lucid and Maverick. From time to time, especially a few minutes after boot, the iowait goes between 50-100% and the box is unusable. Everything that tries to access the disk freezes. I have the following setup: Hard disk: Model Family: Western Digital Caviar Green family Device Model: WDC WD15EADS-00P8B0 Serial Number: WD-WMAVU0391287 Firmware Version: 01.00A01 User Capacity: 1.500.301.910.016 bytes I have a quad core Intel Core2 Q6600 processor, and 4G of memory. When the high iowait occurs, usually 4 processes are active: kdmflush (two procs) jbd2/dm-0-8 jbd2/db-1-8 and a few more starving user processes of course. I know this from top and iotop. Any suggestions about why this is happening? There are a lot of q/a-s about linux and high iowait, but none of them helped so far, I even tweaked the hard disk not to park the head in every 8 seconds (Load cycle count is 50334!!!!! :o ), but nothing. Problem persists. Thank you in advance.

• Load Sharing Regarding Large Websites

  - by JHarley1

  Hello, I have a question regarding Load Sharing for large websites. My Understanding: So if you have a website that has millions of fits a day you will need to have an architecture that can support this sort of pressure. You can either do one or two things: Invest in a single large server that has huge amounts of processing power, memory and storage (such as Microsoft's TerraServer). Spread the load of your website across a number of machines. Let me tackle the second approach, so you have a collection of machines all running Web Server Software and all having access to identical copies of the websites pages. You can either spread the load across these machines using a cyclic pattern in a DNS or you can use a Load Ballancing Switch. The advantages of this approach is: - Redundancy - servers can fail and the others would "pick up the slack" - Incremental - the ability to easily add new machines to this set-up. My Question's Is there a Virtual approach to this issue of load balancing now? If the website runs from a database - is there still only a single copy of the database? If a user had a session running on one Server (e.g. they had gone to www.example.org and had been assigned to Server 2 - were they had created a session) if they refreshed the website (and were allocated Server 3) would they still have their session? What are the other disadvantages associated with Load Balancing? Many Thanks, J

• postfix says mail sent ok, message does not arrive in ISPs inbox? no reject in log?

  - by Nick

  When I send a test message from my mail server to my @bellsouth.net email, The postfix log shows it was sent OK, but the message never arrives in my bellsouth inbox. Shouldn't I get a failure notice or a bounce if At&T is blocking the messages? I'm trying to troubleshoot why some customers aren't getting emails, but if there's nothing in mail.log to say the message is rejected, how do I know which messages were delivered successfully? The log shows: Feb 27 09:02:36 MyHOSTNAME postfix/pickup[26175]: D53A72713E5: uid=0 from=<root> Feb 27 09:02:36 MyHOSTNAME postfix/cleanup[26487]: D53A72713E5: message-id=<[email protected]> Feb 27 09:02:36 MyHOSTNAME postfix/qmgr[5595]: D53A72713E5: from=<[email protected]>, size=878, nrcpt=1 (queue active) Feb 27 09:02:37 MyHOSTNAME postfix/smtp[26490]: D53A72713E5: to=<[email protected]>, relay=gateway-f1.isp.att.net[204.127.217.16]:25, delay=0.57, delays=0.11/0.03/0.23/0.19, dsn=2.0.0, status=sent (250 ok ; id=20120227140036M0700qer4ne) Feb 27 09:02:37 MyHOSTNAME postfix/qmgr[5595]: D53A72713E5: removed The AT&T server accepted the message, right? I happen to have an At&T/Bellsouth email, but I don't have an account with every ISP we send to. I need some way of knowing if a message is getting to its destination or not. Is there any setting in my main.cf file that would affect whether or not we get reject/bounce notices?

• Outlook error-'Can't open e-mail folders.You must connect to Exchange w/ current profile before you can sync folders w/ your Outlook data file'

  - by Emilio

  Note that the error message I put in the title of this question is abbreviated. The actual error message is below. I have an Exchange account and using Outlook 2010 as the client. I run in Cached Exchange Mode and have an .OST file locally. Recently I uninstalled and reinstalled office. I set up a new mail profile when prompted by Outlook 2010 upon first execution of the program. In my initial attempt, I pointed the data file at my existing OST file. In my second attempt, I had Outlook create a fresh empty file. In both cases I'm getting the error 'Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost).', also shown in this screenshot -- http://drop.io/4rc9v9o/asset/outlook-error-png. I don't know how to connect with the current profile - that's what I thought I did when I created a new .OST file? I've had this problem for several days so my OST file is now out of date. Once I get things running I obviously want my active mailbox to update the OST, not the other way around.

• Multi-IP address zimbra server DNS PTR records and spam

  - by David Fraser

  We have a mail server running Zimbra (ZCS 6.0.8). The server has 5 active public IP addresses in the same subnet. (.226-.230). I currently have A records for each of these (host0.domain.com..host4.domain.com), with the main host.domain.com of the machine pointing to .226. Our host has ended up being listed on the SORBS DUHL list (even though it's in a server farm). According to them you can get removed quickly by checking that your host has an MX record, an A record, and a PTR record that points back to the hostname given in the MX record. I tried setting the PTR records so that each of these addresses resolved back to their A record (i.e. .228 had a PTR to host2.domain.com). However, I then got mail being rejected from other servers because when Postfix (under Zimbra control) sends out mail, it uses the main hostname for the HELO - there doesn't seem to be any way to override it. So the PTR records currently say host.domain.com for all 5 IP addresses. What's the correct way to handle this? Should I have an A record for the domain that points to all the IP addresses (for round-robin handling)? I'm nervous of changes that could cause problems, so I'm wondering what the standard way to handle a multiple-IP-address mail server is.

• CentOS - mdadm raid1 drive won't mount to default location

  - by danny

  I'm running CentOS 5.5, the system, boot, swap, etc. is all on /dev/sda and I have two identical single-partition drives /dev/sdb1 /dev/sdc1 that are configured in RAID1 (using mdadm). It was working fine (configured to mount to /mnt/data in the fstab file) and I recently let yum install a couple of automatic updates without paying attention to what they were, and now it doesn't work. Raid is working fine (dmesg shows it gets loaded correctly). mdstat shows: # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdc1[1] sdb1[0] XXXX blocks [2/2] [UU] unused devices: <none> Additionally, I can mount it anywhere other than its default directory (i.e. the following works, and I can read data off the drives). # mount /dev/md0 /mnt/data2 EXT3-fs warning: mounting fs with errors, running e2fsck is recommended But when I run the following I get: # mount -a mount: /dev/sdb1 already mounted or /mnt/data busy It says nothing is mounted when I try to umount /dev/sdb1 or umount /mnt/data, so I assume it's the second of those errors. However, lsof | grep mnt shows nothing. The weird thing is that I can save files in /mnt/data. So something is obviously mounted there, but when I try to umount it I get the error that nothing is mounted. /etc/mtab doesn't mention any of the partitions or files I am trying to work with, and fstab just has that one line I mentioned above that is supposed to mount my raid partition. Again, it was all working fine until I On Google I've found a few things about dmraid interfering with mdadm after an update, but I yum remove'd dmraid and rebooted and it didn't help. I'm really confused and need to get this working to get on with my work!

• MySQL not releasing temp file descriptors

  - by Wakaru44

  Since a few days ago, we’ve been experiencing some serious problems with our MySQL installation: MySQL keeps opening temporal files (normal behaviour) but these files are never released. The consequence is that, eventually, the disk space is exhausted and we have to restart the service and clean up /tmp manually. Using lsof, we see something like this: mysqld 16866 mysql 5u REG 8,3 0 692 /tmp/ibyWJylQ (deleted) mysqld 16866 mysql 6u REG 8,3 0 707 /tmp/ibf5adsT (deleted) mysqld 16866 mysql 7u REG 8,3 0 728 /tmp/ibGjPRyW (deleted) mysqld 16866 mysql 8u REG 8,3 0 5678 /tmp/ibMQDLMZ (deleted) mysqld 16866 mysql 13u REG 8,3 0 5679 /tmp/ibQAnM42 (deleted) Maybe it's not related, but when we shutdown the server, the files are finally freed, and we can see the following warnings in the MySQL log: 121029 7:44:27 [Warning] /usr/local/mysql/bin/mysqld: Forcing close of thread 1333 user: 'xxx' 121029 7:44:27 [Warning] /usr/local/mysql/bin/mysqld: Forcing close of thread 1156 user: 'yyy' 121029 7:44:27 [Warning] /usr/local/mysql/bin/mysqld: Forcing close of thread 1151 user: 'zzz' where 'xxx', 'yyy' and 'zzz' are distinct mysql users (and the only 3 users with active connections to the database). We have a few theories: There is a problem in the OS, that keeps file handlers open. Could it be possible that the OS "delete" operation blocks the threads until shutdown? This may explain the warning at shutdown and the fact that files are finally deleted when the process dies. Until now, data sets were so small that temp files were relatively small and there was enough time to release the file handles without exhausting disk space. We are using Mysql 5.5 on a RHEL 6.2 with the default kernel.

• MSE updating fails, no warning or error message.

  - by WebDevHobo

  I'm running Windows 7 Ultimate, 32-bit. For the last couple of days, MSE doesn't fails to update, remaining stuck at version 1.75.119 I presume that an error log is created somewhere, or an event log, but I don't know where to find those. It just says "connection failed". Tried it at home, at work and friends places, but never works. Restarted computer a lot of times now, checked for Microsoft Updates in general, but nothing shows up. EDIT: I've opened a bounty for this, because I really don't know what to do anymore. The oldest answer(the long post) here did not work. Besides this problem, I'm having trouble using MSI installers too. I've had to add the SYSTEM group to a lot of maps and give them full control, but shouldn't the SYSTEM already be there? Also, I had to remove the "read-only" attribute from the ProgramData and Users folders, add the SYSTEM group there too and give them full control. Only then will the MSI install work and even then, it says I doesn't have the rights to create a shortcut on the desktop. Don't know what I need to modify and where for that. I'm saying this because I don't know how MSE updates, but if they use MSI files to do that, that might explain things. The SYSTEM group remains added, but every time I take away the read only attribute, click OK and check the settings again, read-only is still active... That's all I know. Screenshot, all those updates were manual:

  I have a customized live fedora 12 USB which is working fine. What i want to do is to make a partition of my hard disk bootable so that my customized fedora can be run from hard disk. To accomplish this i did the following steps: Created a primary partition(/dev/sda2) and format it as ext3 and set it as active. Copy all the files in the live usb to /dev/sda2. Following are the live usb contents(all directories): a. boot b. EFI c.

• Why do I often have to refresh pages I navigate to once for them (or content in them) to load?

  - by GetOutOfBox

  I have noticed a bizarre pattern when using my PC, that when I open a link to a website, it often will often take a very long time to load, or time out. Sometimes content on the website will be drawn, but again, it seems to get "stuck" for an unusual amount of time before finishing. Most affected is Youtube; almost every time I navigate to a youtube video from another website such as Google, the video will not begin playing, but will instead just display the player controls with a black screen where the video should be and the buffering symbol, usually before displaying an error such as "The video failed to load". The unusual part of this problem is that whenever this happens, refreshing the page always causes it to load almost immediately the second time around, without any problems. Note that I'm not talking about how some browsers will dump whatever has been cached to the "pallet" briefly when the page is refreshed or loading stopped; but that the second time loading the website being faster. I have done my best to rule out some of the obvious causes: My Windows 7 desktop computer is the only device that seems to be affected. I use Firefox on it (latest version, flash updated, etc). My connection has more than enough bandwidth (30 megabits down, 4 up), and I've even tried QoSing all other devices to make sure this isn't happening due to usage spikes. Wireshark is not showing any clearly unusual network activity (i.e frequently dropped packets).

• Cron won't use msmtp to send emails in case of failed cronjob

  - by Glister

  I'm trying to configure a machine so that it will send me an email if one of the cronjobs output something in case of an error. I'm using Debian Wheezy. Cron is working normally (without the email functionality). msmtp is installed and configured. Have already symlinked /usr/{bin|sbin}/sendmail to /usr/bin/msmtp. I can send email by using: echo "test" | mail -s "subject" [email protected] or by executing: echo "test" | /usr/sbin/sendmail Without the symlink (/usr/sbin/sendmail) cron will tell me that: (CRON) info (No MTA installed, discarding output) With the symlinks I get: (root) MAIL (mailed 1 byte of output; but got status 0x004e, #012) Can you suggest how to config the cron/msmtp pair? Thanks! EDIT: Note: I've written "msmtpd" by mistake. Its not a daemon but rather an SMTP client named just "msmtp" (without the "d" ending). It is executed on demand and it is not running in the background all the time. When I try to send an email by using msmtp like that it works: echo "test" | msmtp [email protected] On the far side, in the logs of the SMTP server I read: Nov 2 09:26:10 S01 postfix/smtpd[12728]: connect from unknown[CLIENT_IP] Nov 2 09:26:12 S01 postfix/smtpd[12728]: 532301C318: client=unknown[CLIENT_IP], sasl_method=CRAM-MD5, [email protected] Nov 2 09:26:12 S01 postfix/cleanup[12733]: 532301C318: message-id=<> Nov 2 09:26:12 S01 postfix/qmgr[2404]: 532301C318: from=<[email protected]>, size=191, nrcpt=1 (queue active) Nov 2 09:26:12 S01 postfix/local[12734]: 532301C318: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=0.62, delays=0.59/0.01/0/0.03, dsn=2.0.0, status=sent (delivered to command: IFS=' ' && exec /usr/bin/procmail -f- || exit 75 #1001) Nov 2 09:26:12 S01 postfix/qmgr[2404]: 532301C318: removed Nov 2 09:26:13 S01 postfix/smtpd[12728]: disconnect from unknown[CLIENT_IP] And the Email is delivered to the target user. So it looks like that the msmtp client is working properly. It has to be something in the cron/msmtp integration, but I have no clue what that thing might be. Can you help me?

• Improving browser performance while using lots of tabs?

  - by Andrew

  My browsing habits cause me to open lots of windows and tabs, either related to different projects I'm working on or things I may want to read later. I use OSX and use about 5 spaces with multiple windows in each space. The problem is eventually I'll have around 200 or more tabs open (spread over 15-20 windows) that I don't want to close. Needless to say, my computer's performance starts to degrade. As I write this on my mobile, Safari on my laptop is locking up the computer. I used to use Chrome but found better performance with Safari. What I'd like to know, is there a graph of browser performance based on tab usage? I don't need a browser that keeps all tabs active. It would be great if the browser could increase performance by "putting tabs to sleep". Or if there was some sort of tool for saving a "workspace" of tabs that you could reactivate the next time you are working on that project. What sort of solution can you recommend to solve this problem?

• Bluehost Emails Getting Blocked

  - by colithium

  A site for my client has the run-of-the-mill "website with users" email pattern. Create an account, get an activation email. Get an email when a subscription is expiring, etc. The site is hosted on Bluehost and currently it uses php's mail() function. There isn't much configuration that is allowed (as far as I know). The trouble is, about a third of these emails disappear into the void. They aren't in spam or junk folders, there's no bounce message, they just cease to exist. I've read about Bluehost email troubles but I can't figure out what my options are for fixing it. These aren't marketing emails, ie they have user-specific information contained within them. I suppose if a solution offers a good templating system that would be fine. What are my options? Excerpt of headers when delivered to a Gmail address: Received-SPF: neutral (google.com: 00.000.000.000 is neither permitted nor denied by best guess record for domain of domain@box###.bluehost.com) client-ip=00.000.000.000; DomainKey-Status: good Authentication-Results: mx.google.com; spf=neutral (google.com: 00.000.000.000 is neither permitted nor denied by best guess record for domain of domain@box###.bluehost.com) smtp.mail=domain@box###.bluehost.com; domainkeys=pass [email protected]

• Site to Site VPN problem, connection succesful data only oneway?

  - by Charles

  To start things off, I'm not the actual Administrator for the VPN Server, but he is also at a loss so I thought I'd ask it here. I know it's a Cisco ASA Firewall/VPN. I have a router that connects to the Cisco VPN server, it does so succesfully. I can ping everything within the remote network and from the remote network into my own. I've been able to SSH into a remote server over VPN as well, it all seems to work; until there's some more data returned. A quick example would be an internal webserver. The default homepage simply redirects, so only sends back HTTP headers with a "Location:". I receive this on my computer, but when I request the actual page then (which isn't that big) I don't get a response at all - it just stalls. And it does this for other services as well, for example SSH. I can do a couple of things while connected, but if there's more than xx output it seems to do nothing. The connection remains active throughout all of this. Has anyone ever experienced anything like this before / know what the problem might be? Another user who has a site-to-site connection with this VPN using the -exact same setup- has no problems, the only difference is that I have around 200ms ping to the VPN server/network because of a very long distance (other continent).

• Apache Process question about RAM usage

  - by Andrew Fashion

  So everytime I load a new page, I notice a new HTTPD process opens, every time I click a page, and each process says it's using anywhere from 2-4.5% of memory. Does that mean every single process is running at that time using 2-4% of RAM? It's a brand new server and I'm the only one on the server at the moment. Or does it mean all the other processes are dying, and only the new one is active. Because 4% of my 2048MB of RAM is already 82MB for just one process!?!? Let me know, because I am trying to determine what I need to beef my server up in order to handle high loads of traffic. I'm expect to get 20,000 uniques per day on launch. I am currently running a Dual Quad Xeon server, with only 2GB of ram, I will upgrade to 8GB or more shortly. Let me know what you suggest! thank you [root@D18634 log]# top | grep 'httpd' 11315 apache 15 0 362m 82m 24m R 12.3 4.1 0:03.00 httpd 11310 apache 16 0 322m 41m 21m S 5.7 2.1 0:02.98 httpd 11315 apache 15 0 362m 83m 25m S 24.3 4.1 0:03.73 httpd 11319 apache 16 0 324m 42m 20m R 1.0 2.1 0:01.85 httpd 11319 apache 16 0 362m 82m 23m R 78.5 4.1 0:04.21 httpd 11321 apache 16 0 323m 44m 23m S 35.3 2.2 0:04.13 httpd 11319 apache 15 0 361m 82m 23m S 8.3 4.1 0:04.46 httpd 11321 apache 15 0 323m 44m 23m S 35.9 2.2 0:05.21 httpd 11313 apache 15 0 324m 41m 19m S 48.6 2.1 0:03.23 httpd 11322 apache 16 0 354m 72m 20m R 11.0 3.6 0:05.11 httpd 11322 apache 16 0 354m 72m 20m S 23.9 3.6 0:05.83 httpd 11314 apache 16 0 355m 75m 22m R 18.3 3.7 0:04.64 httpd

• Starting nginx with systemctl fails, but running the command manually doesn't

  - by Ivan

  On Arch Linux, for some reason, when I try to start nginx with the command "systemctl start nginx", it fails, with this being the output of "systemctl status nginx": Loaded: loaded (/etc/systemd/system/nginx.service; enabled) Active: failed (Result: exit-code) since Wed 2013-10-30 16:22:17 EDT; 5s ago Process: 9835 ExecStop=/usr/bin/chroot --userspec=http:http /home/nginx /usr/bin/nginx -g pid /run/nginx.pid; -s quit (code=exited, status=126) Process: 3982 ExecStart=/usr/bin/chroot --userspec=http:http /home/nginx /usr/bin/nginx -g pid /run/nginx.pid; daemon on; master_process on; (code=exited, status=0/SUCCESS) Process: 10967 ExecStartPre=/usr/bin/chroot --userspec=http:http /home/nginx /usr/bin/nginx -t -q -g pid /run/nginx.pid; daemon on; master_process on; (code=exited, status=126) Main PID: 3984 (code=exited, status=0/SUCCESS) CGroup: /system.slice/nginx.service ...but when I run /usr/bin/chroot --userspec=http:http /home/nginx /usr/bin/nginx -t -q -g "pid /run/nginx.pid; daemon on; master_process on;" and then /usr/bin/chroot --userspec=http:http /home/nginx /usr/bin/nginx -g "pid /run/nginx.pid; daemon on; master_process on;" as root, all it does is return a warning, but works just fine: nginx: [warn] the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1 Why is it doing that?

• Architecture for highly available MySQL with automatic failover in physically diverse locations

  - by Warner

  I have been researching high availability (HA) solutions for MySQL between data centers. For servers located in the same physical environment, I have preferred dual master with heartbeat (floating VIP) using an active passive approach. The heartbeat is over both a serial connection as well as an ethernet connection. Ultimately, my goal is to maintain this same level of availability but between data centers. I want to dynamically failover between both data centers without manual intervention and still maintain data integrity. There would be BGP on top. Web clusters in both locations, which would have the potential to route to the databases between both sides. If the Internet connection went down on site 1, clients would route through site 2, to the Web cluster, and then to the database in site 1 if the link between both sites is still up. With this scenario, due to the lack of physical link (serial) there is a more likely chance of split brain. If the WAN went down between both sites, the VIP would end up on both sites, where a variety of unpleasant scenarios could introduce desync. Another potential issue I see is difficulty scaling this infrastructure to a third data center in the future. The network layer is not a focus. The architecture is flexible at this stage. Again, my focus is a solution for maintaining data integrity as well as automatic failover with the MySQL databases. I would likely design the rest around this. Can you recommend a proven solution for MySQL HA between two physically diverse sites? Thank you for taking the time to read this. I look forward to reading your recommendations.

• Git fails to push with error 'out of memory'

  - by jwir3

  I'm using gitosis on a server that has a low amount of memory, specifically around 512 MB. When I try to push a large folder (happens to be a backup from an android phone), I get: me@corellia:~/Configs/$ git push origin master Counting objects: 18, done. Delta compression using up to 8 threads. Compressing objects: 100% (14/14), done. fatal: Out of memory, malloc failed MiB | 685 KiB/s error: pack-objects died of signal 13 error: failed to push some refs to 'git@dagobah:Configs' I've been searching the web, and notably found: http://www.mail-archive.com/[email protected]/msg01747.html as well as http://git.661346.n2.nabble.com/Out-of-memory-error-during-git-push-td5443705.html but these don't seem to help me for two reasons: 1) I am not actually out of memory when I push. When I run 'top' during the push, I get: 24262 git 18 0 16204 6084 1096 S 2 1.2 0:00.12 git-unpack-obje Also, during the push if I run /head/meminfo, I get: MemTotal: 524288 kB MemFree: 289408 kB Buffers: 0 kB Cached: 0 kB SwapCached: 0 kB Active: 0 kB Inactive: 0 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 524288 kB So, it seems that I have enough memory free, but it's actually still failing, and I'm not enough of a git guru to figure out what is happening. I would appreciate it if someone could give me a hand here and tell me what could be causing this problem, and what I can do to solve it. Thanks!
