• glib2 64-bit compile fails on Solaris 10

  - by Aaron

  I'm encountering a problem building glib-2.26.1 on a Solaris 10 box - 64-bit. Goo diligence doesn't turn anything up, but no matter what I do the build fails in the same way. I've tried using the Sun Studio compiler, gcc (SFW) to no avail. When I compile I get the following error: [root@foo glib-2.26.1]$ export CC=/opt/solstudio12.2/bin/cc [root@foo glib-2.26.1]$ export CFLAGS="-m64" ...configure goes normally...

• Can't Get Mac Mini to turn on - no screen, no beep, only the fan, power light, and optical drive noi

  - by pibyers

  I have an Intel-based Mac mini mid-2007 (Model A1176). This is the computer my kids use so I don't use it regularly. The computer had been working fine until one day my kids told me that it no longer works. The computer will not boot up. When I turn it on the fan turns, the white power light in the front turns on, and there is a sound that appears to be from the optical drive (rather than hard drive). I don't get anything to the monitor, nor do I get any dings or other start up sounds from the computer. Here is what I've tried thus far to no avail: 1) Swapped out the monitors early on since I figured that was my weak link - no change 2) Reset the PMU - no change 3) Tried to boot up from the System Disk - The mini loaded the dvd into the drive, but nothing else (I can't eject the disk so I can put it back) 3) Start up the computer in target mode connected to another mac - I tried this too, but I never received a chime or the disk show up on the other mac. I'm about out of ideas apart from scraping the computer. Does anyone have any ideas that I can try? Again, nothing has been done to the computer in at least 6 months when I upgraded the RAM. I'm also still on Leopard. Thanks.

• nVidia performance with newer X and newer driver abysmal with Compiz

  - by Nakedible

  I recently upgraded Debian to Xorg 2.9.4 and installed nvidia-glx from experimental, version 260.19.21. This was somewhat of an uphill battle as the dependencies for the experimental nvidia-glx package are still somewhat broken. I got it to work without forcing the installation of any packages and without modifying the packages. However, after the upgrade compiz performance has been abysmal. I am using the desktop wall plugin and switching viewports is really slow - takes a few seconds for each switch. In addition to this, every effect that compiz does, such as zoom animations for icons when launching applications, takes seconds. The viewport switching speed changes relative to the amount of windows on that virtual screen - empty screens switch almost at normal speed, single browser windows work almost decently, but just 4 rxvt terminals slows the switches down to a crawl. My compiz configuration should be pretty basic. Xorg is likewise configured without anything special - the only "custom" configuration is forcing the driver name to be "nvidia". I've fiddled around with the nvidia-settings and compizconfig trying different VSync settings, but none of those helped. My graphics card is: NVIDIA GPU NVS 3100M (GT218) at PCI:1:0:0 (GPU-0). This is laptop GPU that is from the Geforce GTX 200 series. Graphics card performance should naturally be no problem.

• Bash wonkyness on Ubuntu versus RHEL

  - by d34dh0r53

  Fellow faulters, I'm playing around with a one liner that I've developed on a RHEL 5.4 box and I have it working perfectly: TOTAL_RAM=`free | grep Mem: | awk '{ print $2 }'`; \ ps axo rss,comm,pid | awk -v total_ram=$TOTAL_RAM \ '{ proc_list[$2] += $1; } END { for (proc in proc_list) \ { proc_pct = (proc_list[proc]/total_ram)*100; printf("%d\t%s\t%0.2f%\n", proc_list[proc],proc,proc_pct); }}' \ | sort -n | tail -n 10 Which outputs something like the following on my RHEL box: 3736 logmon 0.01% 4156 EvMgrC 0.01% 4692 hald 0.01% 5020 ntpd 0.02% 6252 sshd 0.02% 7784 cvd 0.02% 9224 snmpd 0.03% 13068 dsm_sa_datamgr3 0.04% 23320 dsm_om_connsvc3 0.07% 4249864 mysqld 12.90% However on my Ubuntu 9.04 slice I get this: awk: run time error: not enough arguments passed to printf("%d %s %0.2f% ") FILENAME="-" FNR=104 NR=104 33248 console-kit-dae 3.17 I think it has to be bash that is borking something, but I'm really not doing anything that should be that bash specific. The RHEL box is running: # yum info bash | grep -e Version -e Release Version : 3.2 Release : 24.el5 And the Ubuntu box: # apt-cache show bash | grep -e Version Version: 3.2-5ubuntu1 I haven't dug into this super deeply, and thought I'd ping my fellow johnnys to see if you've ever run across this before. /bow

• Moving domain and keeping IMAP email - Linux Evolution, Mac Mail

  - by Douglas Squirrel

  This question is about keeping email during a server move, where the clients are Linux (me) and Mac (my wife) using IMAP. I receive email at [email protected] using a webmail service that my hosting company (1and1) provides. I read it via IMAP in evolution, so I should have copies of all the emails on my local machine. I have just moved mydomain.com from one type of account to another, and the hosting company don't move my existing email on the server when I do this - I assume they move my account to a different mailserver, and don't choose to provide a migration path for the email to move too (yes, this is annoying). Before migrating, I backed up Evolution (File - Backup settings) and did a spot-check in the evolution-backup.tar.gz file to be sure that my mail was in there. After migrating, I restored (File - Restore settings) and had hoped that I would see all my mail again. Unfortunately, Evolution just shows me new mail sent to the account, not the old mail. Is there a way to get the old mail back in the mailserver, or at least displaying in Evolution, as it was before the move? If not, can I read it in some convenient way, e.g. in Evolution offline or in a text file (then I can pick the mails I really want to keep and resend them to myself)? Also, I am about to do a similar move for my wife's domain, [email protected]. She reads her mail on a Mac using IMAP to Apple Mail. Is there anything I can do to make the move smooth for her? (I have backed up [her user]/Library/Mail already, but not sure what to do once the move is done.)

• AD server within another network - DNS issues

  - by Harry Muscle

  Here's a quick summary of the environment I support: we have a domain (domain A) that has about 20 client computers. The domain server for this domain and all the clients sit within the network infrastructure of a larger domain (domain B). All the computers get their network settings via DHCP from domain B's servers. I have no control and am unable to make changes to anything to do with domain B. The problem I have is that currently in order for my domain's (domain A) clients to be able to resolve the domain server and the shares on it they have their DNS server IP address set to domain A's domain server (via the default GPO). Unfortunately when a laptop (windows and mac) gets taken home, they are still looking for the domain server as their DNS server and obviously can't access the internet correctly outside of our environment. Ideally I need a solution where the machines use domain A's domain server as their DNS when inside the office and use what ever DNS server DHCP gives them when they are outside the office. However, since I have no control over the office DHCP server, I'm not sure how this can be accomplished. Any help and advice that anyone can offer is highly appreciated. Thanks, Harry P.S. The solution I'm trying to find needs to require no involvement from the user.

• Rails/Mongo across multiple different geo-regions

  - by wmarbut

  I have a system that by necessity requires physical presence in three or more different locations and I need advice on structuring in such a way that my database stays replicated in a timely manner without horrible latency. I've seen mysql access and replication be incredibly slow when the application server was trying to talk to a node that wasn't physically collocated. In this case I am using mongodb. The stack is linux/passenger/ruby/rails/mongodb. The database is write heavy and read light. The infrastructure is Amazon EC2 The application layer must be physically located in 3 or more different locations. I can't justify this requirement further than it is a requirement. The database, however needn't be located in more than one location if it can be written to quickly from other locations. From reading mongo's documentation, mongo replication seems like more of a candidate than sharding b/c my datastore is not huge. However I don't see anything that addresses the issue of speed for servers communicating across large distances with potentially high latency.

• Using 1920x1200 mode on SyncMaster T260HD in Linux

  - by dagorym

  I just got a Samsung SyncMaster T260HD monitor. It works straight out of the box with Windows but I can't seem to get it to work with Linux, which is my primary OS for day to day work. The computer boots up but when going into graphical mode on Linux the monitor gives me a "Mode not supported" error and doesn't display anything. I booted up windows and, using PowerStrip, grabbed the exact ModeLine that should be used to get the equivalent setting in Linux and added it to my xorg config file but it doesn't seem to help. the ModeLine is: ModeLine "1920x1200" 153.9 1920 1984 2016 2080 1200 1203 1209 1235 +hsync -vsync This is the modeline for the working display settings in windows but it doesn't seem to work in Linux My complete entry in the xorg.conf file for the monitor is Section "Monitor" Identifier "Monitor0" ModelName "SyncMaster" DisplaySize 518 324 HorizSync 30.0 - 81.0 VertRefresh 56.0 - 75.0 Option "dpms" ModeLine "1920x1200" 153.9 1920 1984 2016 2080 1200 1203 1209 1235 +hsync -vsync EndSection I'm running Scientific Linux 5.4 (clone of Redhat Enterprise Linux 5.4) but I've tried booting with a recent Linux Mint Distro as well as Ubuntu 9.04 and had the same problem. Any suggestions on other things I should try or might be missing? If anyone's gotten this to work I'd love to know. Thanks.

• HTTP Upload Problems

  - by jfoster

  We are running a marketplace on ColdFusion8 and IIS with a widely geographically distributed user base and have been receiving complaints of issues with some HTTP uploads. Most of the complaints are coming from geographically distant locations from our main datacenter on the US east coast. I've attempted to upload the same 70MB file from a US West coast test server to both our main site and a backup running the same code on a different network route and I saw the same issues fairly consistently in both places, so I've ruled out the code, route, and internal network errors. I've also tested uploads using both the native cf upload tag and a third party tool called SaFileUp. I saw the same issues with both upload tools, so I also don't think this is necessarily a ColdFusion problem. I don't have any problems uploading the test file from the East coast to other east coast servers, so I'm beginning to think that the distance between our users and our equipment is a factor. I've also found that smaller files are more likely to succeed than large ones (< 10MB) I tried the test upload with both IE and FF and did notice a difference in the way that the browsers seemed to handle packet errors. IE seemed to have a tough time continuing an upload after dropped / bad packets, whereas FF seemed to have the ability to gracefully resume an upload after experiencing packet problems. Has anyone experienced similar issues? Is there anything we can do on our side to make uploads more forgiving to packet loss or resumable after an error? A different upload tool etc… Do we need upload servers in more than one location to shorten the network routes between clients and servers? Does anyone think that switching uploads to SSL will help (no layer7 packet sniffing may lead to a smoother upload). Thanks.

• Confused about the Windows 7 Preinstallation Kit

  - by David Brown

  I build custom PCs and would like to use the Windows 7 Preinstallation Kit to make installation go a little quicker and customize the Windows image. However, since each PC is built to a particular customer's specifications, the hardware will rarely be the same. So, I would like to have a single answer file that will work for everything. I'm not sure if that's possible, however. What I mostly want to do for now is add my support information as well as pre-set anything that I would normally change after each installation completes. I have a Windows 7 Professional Upgrade DVD set (both 32-bit and 64-bit), but no OEM disks. I copied the Install.wim file to my local drive and opened it in the Windows System Image Manager, but it asks me to choose a catalog file specifically for each edition of Windows 7. Will this limit the answer file to whichever edition I choose? I would think choosing Starter would give me the most basic settings, which would apply to all other editions, but I'm not entirely sure of this. I don't intend to install any extra applications or drivers. I merely want to insert an OEM disk, my OPK USB drive, and have it work for whatever edition of Windows 7 I'm installing. If a large number of similarly-configured PCs need to be built, I'll go ahead and create a custom answer file in that case, but for a single machine order, that seems like overkill. In addition, do I need a separate answer file for 32-bit and 64-bit versions of Windows 7? Or will it work for both, even though I copied the Install.wim file from the 32-bit disk? Thanks!

• Start daemon after specific samba share is mounted

  - by getack

  I axed this question on AskUbuntu, but it's not getting any traction from there... So I'll try here as well: I have a homebrew headless NAS running 12.04. In it I have a bunch of disks that are presented as a samba share thanks to Greyhole. If I want to do anything to the files within this share, I must do it through greyhole so that everything is updated properly. Thus, the share must be mounted locally and then accessed from there if I want to work on the files from the local machine. I do this mounting automatically thanks to these instructions. I also have Deluge installed that takes care of all my torrenting needs. Deluge's default download location is in this share, so that all the downloads are immediately available to the rest of the network. Obviously for everything to work, the share must be mounted, otherwise Deluge is going to have a problem downloading to it. The problem is, it seems like Deluge is starting before the shares are mounted when the system boots. So downloading/seeding does not continue automatically after boot. I have to log in and force a manual rescan and start on each torrent otherwise all the torrents just hangs on the error. Is there a way I can make deluge start after the shares got properly mounted? I looked into Upstart's emits functionality but I cannot seem to get it to work properly. Any advice?

• Using bind (named) as a public proxy server

  - by TrentDavis

  We have a Python DNS server that does a bunch of stuff to figure out values it should return for various DNS records. This works nicely, however as it is Python, the performance under high load won't be great. What I would like to do is have a "proxy" bind server sit in front of it to return results to the public internet. This will cache the results (typically 15 minutes, some records are a few seconds), so the load on the Python server will be greatly reduced as it will only see one look up per domain (only about 100 domains) every 15 minutes. The data in these domains changes a lot, so using a master won't work as it will constantly be changing. I have something setup that looked like it would work great (using a forwarder for the zone), and tested it with dig etc, all going great. However when we went to go live with it, things weren't working, and we figured out that named is not setting the "Authoritative" bit (fair enough, it is a forwarder). So my question is, can we tell bind to set the Authoritative bit for forwarded domains? I have looked at all the doco I can find, and can't find anything about doing things this way. Most of the doco about using it as a proxy if for a LAN to the internet. Ideally I would like to use bind as it is there and installed (CentOS 5 servers). But at a pinch we could look at a different name server to do the work if it just can't be done with bind. Thanks.

• Windows Server 2008 R2, weird intermittent outgoing connection issues, & Hyper-V Virtual Network

  - by brizz

  My provider says that they run an 'unfiltered' network, so it's not a network issue. Not entirely convinced...but they aren't being very helpful. Basically two days ago started having issues with DNS completely stop working for anywhere between 2-20minutes. This happens roughly every 1-2 hours at least once. I later then found that I am unable to ping ANY external IP address when this is going on. So it's not a DNS issue. Whats even more odd is when this is going on, I STAY connected via RDP, and I can access webpages, etc that are on the server when I access from my home computer. Have tried disabling the firewall--no fix. Have checked Event viewer, the only thing that is there is a warning that DNS has stopped working. I have made no changes/updates to the server. The only thing I have done is add an IP address (don't think it has anything to do with the problem, but wanted to mention everything). Any help/insight/suggestions on how to go about debugging would be much appreciated! update: I am also running Hyper-V, and a virtual network. I just tried pinging (when I have issues), from a Hyper-V machine--and it works, when the main server doesn't.

• sql server 2008 cluster hang when a heavy load is run

  - by Billy OT

  we have a sql server 2008 active/active cluster running on wondows 2008R2 O/S. 14GB RAM, 4xCPU. we have set a ceiling of 12GB for sql server. We're running an agent job which loads 3 million records to a database. during this load the job fails and the cluster seems to attempt to fail over to the other node but unsuccessfully i.e., the cluster address is no longer accessible. we have to manually fail the cluster node back. during the load on viewing task manager we can see that memory usage hits a max of 12.5GB and CPU at times hits 100% on all 4 CPU, but for the most part fluctuates at an average of about 60%. I suppose my question is, will a cluster try to fail over if memory or CPU are taking a heavy hit? or am i barking up the wrong tree? also any ideas why it wouldn't fully fail over? we've crawled through logs, of which there are a lot, and can't find anything useful. we've also tried recreating the issue but it ran successfully at a later time. Also 3 million rows doesn't seem like a lot but in terms of resources should 14GB RAM and 4xCPU not be sufficient? Further information on this, we ran the load again today and corrupted the database! We received the error message : LogWriter: Operating system error 170. It looks like, under the heavy load, the sql cluster attempted to fail over and in doing so migrated a lun (or drive) which meant the disk was no longer reachable. (this is just our theory). The database is now 'suspect' and requiring restoration. The 170 error above also indicates that on failing over to the other node, the sql service could not start as it was already in use, therefore it couldn't fail over fully?? But I'm wondering why would it need to fail over in the first place? My assumptions could be completely wrong on this, so any ideas would be appreciated.

• Exchange eMails In A Mailbox Appear To Be Blocked By A Dud Message

  - by John Judd

  I have a client with an Exchange server on which there are quite a few mailboxes. One mailbox in particular is causing some problems. When an email from a certain address arrives, it appears to prevent Exchange from successfully delivering the email to the Outlook Express inbox. The address in question is from an account with Bigpond, or at least I think it is, I didn't check to see if it was spoofed (only just occurred to me.) Any emails in the queue before the suspect email are delivered, then Express times out. When send/recv is retried those emails are re-received and the process times out again. The process I have for fixing this is to log in to the sever, load Outlook, open the recipients inbox, and delete the suspect email. Then retrying the send/recv on Express successfully retrieves all the messages (except for the deleted message.) This solves the immediate problem, but this has happened several times now, and each time requires the process above to correct it. What I am wondering is if there is anything I can do to fix this permanently. It seems to me that Exchange should reject a dud email message rather than getting stuck. Does anyone know what could be causing this, and how I can fix it?

• How do I fix a corrupt calendar cache?

  - by Blacklight Shining

  I was tailing /var/log/system.log and noticed a sudden wall of text. Looking closer, I saw it was an error CalendarAgent got while trying to save something: Nov 18 11:42:45 rainbow-dash.local CalendarAgent[12321]: CoreData: error: (11) Fatal error. The database at /Users/blackl/Library/Calendars/Calendar Cache is corrupted.

Also, it would probably be a good idea to disable Calendar Agent so it doesn't try to use the database while it's being fixed (that's why I copied it to /tmp before running sqlite3 on it.) How do I disable CalendarAgent and fix its cache?

• Sendmail in Nexenta core 3.0.1

  - by maximdim

  I'm trying to setup sendmail in Nexenta core 3.0.1 (Solaris based OS). All I want is to be able to send emails from that host - like notifications about failures, cron jobs output etc. Initially Nexenta core doesn't have sendmail so here is what I've done: apt-get install sunwsndmu Now there is a sendmail in /usr/sbin/sendmail. When I try to send email from command line: $mail maxim test . It doesn't give me any error but in log file I see: Dec 20 12:41:08 nas sendmail[12295]: [ID 801593 mail.info] oBKHf8u7012295: from=maxim, size=107, class=0, nrcpts=1, msgid=<201012201741.oBKHf8u7012295@nas>, relay=maxim@localhost Dec 20 12:41:08 nas sendmail[12295]: [ID 801593 mail.info] oBKHf8u7012295: to=maxim, ctladdr=maxim (1000/10), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30107, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1] So I guess I need to have SMTP service running. How do I do that in Nexenta? svcs -a | grep sendmail doesn't return anything and # svcadm enable sendmail svcadm: Pattern 'sendmail' doesn't match any instances I'm not married to sendmail so if there are easier ways to achieve y goal I'm open to suggestions as well.

• How to connect through a proxy using Remote Desktop?

  - by scottmarlowe

  So I've got a home server running Windows Server 2003. I use a dual network card setup and Routing and Remote Access to link the internal, private network to the external connection. The external connection hooks directly to my cable modem (so no routers or other devices sitting between). The problem I'm having is that I can't connect remotely from a location outside the house (so connecting to the server's external connection) to the server using either Remote Desktop or VNC. I have enabled both ports in Routing and Remote Access's firewall to allow access, and I have enabled Remote Desktop in Windows Server 2003. The odd thing is that I can access my home server's SVN repository and I can even ping the server's IP. I am using the IP to attempt to connect, though I use a dyndns.com provided name to connect to my SVN repository, so it shouldn't make a difference (I know the IP is getting resolved correctly). Any ideas on where to start diagnosing this one? I haven't seen anything in my server's event log. If any other info is needed, let me know. Thanks. UPDATE: One last piece of information: We use a proxy server at work, which I'm nearly 100% sure is the culprit. I have a workaround--if I connect to our VPN (even though I'm already inside the building) I am able to connect to my home server. This is with VNC. However, is there a way to connect through a proxy using Remote Desktop? ONE MORE UPDATE: Indeed, it was the http proxy I'm sitting behind at work that was causing the issue. An acceptable workaround is to use my VPN connection to bypass the proxy, and I'm in!

• Windows 7 Not Recognizing Camera Nor iPhone as Camera

  - by taudep

  I've been struggling with this one for a few days. I've recently upgraded an older computer to Windows 7 Home Premium. Neither my digital camera (A Canon SD1200IS) nor iPhone are ever detected as cameras, nor ever show up as accessable in Explorer. With the Canon camera, no driver is required. It's supposed to work with the default Windows 7 drivers. However, in the Control Panel's Device Manager, I'm always seeing a yellow icon next to the "Canon Digital Camera" device. I've uninstalled the device and let Windows attempt to reinstall, but it can never find a driver to install. With the iPhone, it's very similar. One big difference, though, is that iTunes can see the iPhone and back it up, etc. However, again when I go to the Device Manager, there's a yellow icon next to the iPhone. I've uninstalled iTunes, reinstalled, rebooted, deleted drivers, and let Window try to reinstall the driver, but it can never find the driver. So there seems to be some correlation that my machine can't detect cameras properly, and that it might be even a lower-level type of driver I'm struggling with. I know that USB however, does work, because I have have an external drive hooked into the machine. I've gone through the web and tried two hours worth of fixes, without success. I feel like if I can get the Canon camera detected, then the iPhone will be on it's way to being fixed too. BTW, I couldn't really find anything of use in the Event viewer. Any and all suggestions welcome.

• Fedora 9 not reconizing hard drive

  - by Andrew Jones

  I am installing Fedora 9 to a PC (specifications at the bottom) and have had a lot of trouble with it recognising the hard drive. To get the Fedora installer to recognize it in the first place I had to pass "ata_generic.all_generic_ide=1 pci=nomsi" to the kernel, after which it installed OK. However, now when I boot the installed OS, I get a "could not find filesystem '/dev/root'" error. I tried passing the same arguments to the kernel at boot as I did when installing but to no avail. I have tried using the default LVM layout and defining manual ones but it made no difference. There is no option in the BIOS to enable AHCI or anything like that, in fact the BIOS is very limited in most respects. I can get into the system by using the installation CD in rescue mode (with those extra kernal parameters) but I'm not sure what to do once in there... Unfortunately using a more recent version of Fedora or even another Linux distribution altogether isn't an option becuase of outside constraints - which is annoying since I know for a fact Ubuntu works fine on this setup. I have not been using Linux that long, so treat me like an idiot - I am one. Any help would be greatly appreciated, thanks! System spec: Intel Atom Z530 CPU @ 1.6 GHz Intel US15W chipset 1 GB DDR2 160 GB SATA harddisk (Samsung HM16HI) 1000 Mbit/s Ethernet port Phoenix BIOS

• Acer Aspire One (mini) mfgd 9/03 locks up also when plugged in

  - by LAURIE ANN

  My problem is almost the same as the Toshiba user (Toshiba A205-5804 freezes when plugged in): Well I have a Toshiba A205-5804 and the problem is that the screen freezes anytime I plug the pc into the external power supply, not as most of the computers having the same issue, my computer DOES freeze in safe mode, and I really can't bear this problem for much longer... It's not an overheat problem, the computer is not getting hot or anything related, I've tried already to change the AC adapter, to boot only with AC and no battery, and also all of these suggestions: The only difference in my case is: I can be using the battery and when it runs down, I can just close the lid and the system goes into hibernation mode. I then plug it in and let it charge. When I think it's finally charged, I can UNPLUG it, open the lid and all is running fine on the battery again. Note: the system was NOT shut down and it still runs as long as I remove the power plug before opening the lid. I have ALL the same issues as the other Toshiba user, also. I was a tech for 9 yrs in my own business and this one has not only stumped me, but anyone I have asked has never heard of this problem. Every repair center wants to charge me for diagnosis, even is they cannot fix it. I would really like to run this system along side of my new Acer Aspire 17" laptop as I need it to finish my grad school work. Any ideas would be GREATLY appreciated. Thanx, Laurie Ann

• running red5 on port 80

  - by ArneLovius

  I have a red5 application http://code.google.com/p/openmeetings that runs under red5, and is accessible on port 5080 and 8443 I've installed it on Ubuntu 10.04 The eventual aim is to have it accessible via https on 443 instead of 8443, but I thought I would initially try on 80 so that any issues were just down to the port configuration and not SSL certificates. I've tried changing the port from 5080 to 80 in the red5.properties file, but it fails to start. In the red5.log I have seen ERROR o.a.coyote.http11.Http11Protocol - Error initializing endpoint java.net.BindException: Permission denied /0.0.0.0:80 In the error.log I have seen ERROR o.a.coyote.http11.Http11Protocol - Error initializing endpoint java.net.BindException: Permission denied /0.0.0.0:80 and ERROR org.red5.server.tomcat.TomcatLoader - Error loading tomcat, unable to bind connector. You may not have permission to use the selected port org.apache.catalina.LifecycleException: Protocol handler initialization failed: java.net.BindException: Permission denied /0.0.0.0:80 There is nothing else installed or running on port 80, so I presume that this is a "needs to be root" situation. I would rather not run an Internet accessible web service as root. I know that Tomcat can run on port 80 by changing “#AUTHBIND=no” to “AUTHBIND=yes” in /etc/default/tomcat6 but I have not been able to find anything similar for red5. Am I on a hiding to nothing, or is there better way than running as root ? Thanks!

• Adding network share as the system account breaks Win7 backup to network

  - by ChrisBenn

  (On Win7 Ultimate x64 SP1) So I've been using Win7 backup to \192.168.0.100\Backup\main-desktop\ for awhile without issue. Yesterday I tried to setup crashplan to synchronize my dropbox folder and a network share. I then found out that crashplan, as it runs under the system account, can't see my user mapped drives. So I created a startup script net use O: \192.168.0.100\Documents /USER:192.168.0.100\username password and set it to run, on startup, after the network interface is up, as the system account. (the username & password are the same for the net use script above, the locally logged in user, and the explicit username/password entered in windows backup). I woke up this morning to find error flags from the windows backup and get "Network location cannot be used" (0x800704B3). If I disable the startup task & reboot then windows backup works fine. I'm not sure why having a mapped drive for another user is killing windows backup (same server, different folder). I can work around the issue by using another program to synchronize the two folders, but I'm completely in the dark as to why this happens (and it's 100% repeatable). Uninstalling the crashplan client doesn't change anything - it's the net use run under the system account that breaks win7 backup (to a network location).

• Gittornado with Nginx fails to push and pull

  - by Josh Buell

  I'm making a simple website to host git repositories, much like github. I'm using Gittornado to handle git Smart HTTP requests, and it works perfectly locally; I can clone, push, pull, etc... But when I put it behind Nginx, git commands stop working, giving no errors except: "fatal: The remote end hung up unexpectedly" I know that it's Nginx that's causing the trouble because if I open the port that tornado is running on and try my git commands through that (i.e. "git pull \http://mysite.com:8000/myrepository master" instead of "git pull \http://mysite.com/myrepository master" [backslashes added because Server Fault says I have too many links]) everything works as expected. The Nginx access and error logs don't seem to say anything interesting, so I'm reasonably sure that it has something to do with the way Nginx is compressing or chunking the requests/responses, causing git to think there's been an unexpected hangup, but I'm not sure what to do to fix it, since this is my first time with Nginx. My Nginx configuration file is basically a clone of the on found here; I've tried commenting out various likely-seeming options to see if they were causing the problem, but none of them fixed it so I assume there's some default behavior I need to suppress, I'm just not sure which. Any thoughts on how to fix this? Since it works not through Nginx, I'm considering just redirecting git requests to the tornado port itself, but this feels like a hack rather than a clean solution...

• Linux: Force fsck of a read-only mounted filesystem?

  - by Timothy Miller

  I'm developing for a headless embedded appliance, running CentOS 6.2. The user can connect a keyboard, but not a monitor, and a serial console would require opening the case, something we don't want the user to have to do. This all pretty much obviates the possibility of using a recovery USB drive to boot from, unless all it does is blindly reimage the harddrive. I would like to provide some recovery facilities, and I have written a tool that comes up on /dev/tty1 in place of getty to provide these functions. One such function is fsck. I have found out how to remount the root and other file systems read-only. Now that they are read-only, it should be safe to fsck them and then reboot. Unfortunately, fsck complains to me that the filesystems are mounted and refuses to do anything. How can I force fsck to run on a read-only mounted partition? Based on my research, this is going to have to be something obscure. "-f" just means to force repair of a clean (but unmounted) partition. I need to repair a clean or unclean mounted partition. From what I read, this is something "only experts" should do, but no one has bothered to explain how the experts do it. I'm hoping someone can reveal this to me. BTW, I've noticed that e2fsck 1.42.4 on Gentoo will let you fsck a mounted partition, even mounted read-write, but it seems only to do so if fsck is run from a terminal, so it can ask the user if they're sure they want to do something so dangerous. I'm not sure if the CentOS version does the same thing, but it appears that fsck CAN repair a mounted partition, but it flatly refuses to when not run from a terminal. One last-resort option is for me to compile my own hacked fsck. But I'm afraid I'll mess it up in some unexpected way. Thanks! Note: Originally posted here.
