  • Cable management techniques

    - by cornjuliox
    How do you manage the giant jungle of cables behind your PC? When you have 2 or more PCs next to each other, you wind up with this giant mess cables that's a pain in the neck to clean especially when both computers are running 24/7 and any fidgeting with the cables is likely to cause data loss and/or angry users. So far I've tried masking tape, cable ties and plain old string but none have been very effective. The masking tape kept the cables in place, but over time they ended up leaving this awful sticky residue on the sides of the cables that just won't come off gets all over your fingers and is horrible horrible horrible. I have nightmares about that stuff. We used cable ties and 'folded' up some of the longer cables so that they weren't any longer than they needed to be, but this meant that the position of some of our devices like the keyboard and the mouse were essentially 'fixed' until we removed the ties. The string didn't work much differently and required that we tie them properly or risk it coming loose. I would switch to a wireless keyboard and mouse, but I don't want to have to deal with the added expense of batteries, even the rechargable ones. Plus I don't want them to die on me at a crucial moment (happened to me once while playing Firearms _<). I know that there are people out there with home/office networks a thousand times more convoluted than mine, so

  • Xen PV packet loss

    - by Delphinator
    I'm having some serious issues with packetloss with one of my servers. This server is a somewhat old (P4-era) machine running Debian Squeeze and Xen 4.0. There are two domUs running on it (both also Debian Squeeze), one gateway and a fileserver. Unfortunatly the processor has no virtualization extensions, therefore only PV can be used. While investigating why our network seems to be slower than it should I found some pretty bad packet loss (~25%). After further investigation and several experiments I did a measurment between the dom0 and one of the domUs: Server listening on UDP port 5001 Receiving 1470 byte datagrams UDP buffer size: 110 KByte (default) ------------------------------------------------------------ ------------------------------------------------------------ Client connecting to dom0, UDP port 5001 Sending 1470 byte datagrams UDP buffer size: 110 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.1.2(domU) port 33817 connected with 192.168.1.100(dom0) port 5001 [ 4] local 192.168.1.2(domU) port 5001 connected with 192.168.1.100(dom0) port 48606 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 46.3 MBytes 38.7 Mbits/sec [ 3] Sent 33020 datagrams [ 3] Server Report: [ 3] 0.0-10.0 sec 46.2 MBytes 38.6 Mbits/sec 0.030 ms 89/33019 (0.27%) [ 3] 0.0-10.0 sec 1 datagrams received out-of-order [ 4] 0.0-10.2 sec 43.0 MBytes 35.3 Mbits/sec 13.074 ms 11575/42256 (27%) tl;dr: 27% packet loss from dom0 to domU with 50Mbit UDP packets. Same thing happens from anywhere in the network. The problem gets better for smaller bandwidths (0.047% for 5Mbit) and worse for higher (59% for 200Mbit) ones. I did increase the CPU-weight of the dom0, there is no swapping going on, and actual networking-hardware is not involved. I never expected Xen (or anything related) to drop packets, and I'm completly clueless what to try next.

  • BTrFS crashhhh?

    - by bumbling fool
    I create a new BTrFS raid10 file system using two 250GB drives and the second partition on a third 80GB drive. I create a subvol and snapshot. I mount the snapshot and start copying 8GB of data to it. It gets to around 1GB and the Desktop disappears and what looks like a non interactive terminal comes up with dump/crash information. I don't have a camera handy or I'd take a picture and post it. It basically looks like stack trace info. CTRL-ALT F7 will eventually bring back the Desktop though but the entire BTrFS portion of the OS is hung and non responsive until I reboot. I've reformated and reproduced this problem 3 times now and I'm about to give up :( I realize it is possible this problem is not entirely BTrFS' fault because I'm on natty which is still alpha. More granular details in case I'm an idiot: 1) Create FS: sudo mkfs.btrfs -m raid10 -d raid10 /dev/sda2 /dev/sdb /dev/sdc 2) Initial temporary mount: mkdir /btrfs && sudo mount -t btrfs /dev/sda2 /btrfs 3) Create subvol btrfs s c /btrfs/vm 4) Create initial snapshot: (optional) btrfs s sn /btrfs/cantremember.snap.something 5)unmount /btrfs and mount /btrfs/vm sudo mount -t btrfs -o subvol=vm /dev/sda2 /btrfs/vm 6) Copy data to subvolume. 7) Balance data across drives: (optional) btrfs f bal <path> (never get to this step 7...) Am I doing something wrong?

  • Domino nchronos.exe multiple instances causing server to die, and Sametime problems

    - by Kevin
    I've had this problem for a few months now. I thought it started when I installed the Traveller software on the server to add ActiveSync support, but I removed that and the problem still persists. Basically new instances of "nchronos.exe" keeps spawning (and not ending), so over a period of a few days the server eventually gets drowned in nchronos.exe processes, stops responding and I need to kill Domino. My process count the last time was up at about 330, and when I killed it and restarted the Domino my process count went to 160. I'm running Domino 8.5.1 with Fix Pack 2. I don't know if it's relevant, but my Domino server was also acting as a Sametime server. At around the same time that nchronos started playing up sametime also stopped working. None of my users can connect to sametime and in the domino log it keeps telling me "stpolicy.exe" has terminated. I've googled for that and tried a few things, but nothing seems to make sametime work again. Any thoughts?? Cheers, Kevin

  • (Zywall USG 300) NAT bypassed when accessing in-house-server From LAN Via domain name

    - by mschr
    My situations is like this; i host a number of websites from within our joint network solution. On the network is basically 3 categories: the known public, registered via mac, given static dhcp lease the anonymous lan connections, given lease from specific dhcp range switches, unix hosts firewall Now, consider following hosts which are of interest 111.111.111.111 (Zywall USG 300 WAN) 192.168.1.1 (ZyWall USG 300 LAN) load balances and bw monitors plus handles NAT 192.168.1.2 (Linux www) serves mydomain1.tld and mydomain2.tld 192.168.123.123 (Random LAN client) accesses mydomain1.tld from LAN 23.234.12.253 (Random External client) accesses mydomain1.tld via WAN DNS A records are setup so that both mydomain1.tld and mydomain2.tld points to 111.111.111.111 - and the Linux www serves the http parts with VirtualHost configurations, setting up the document roots pr ServerName, this is not so interesting though.. NAT rule translates 111.111.111.111:80 to 192.168.1.2:80 (1:1 NAT) Our problem follows; When accessing http://mydomain1.tld from outside (23.234.12.253 example host) the joint network - everything is fine, zywall receives requests via port 80 and maps it to the linux host' httpd. However - once trying to go through the NAT from LAN side (in-house, 192.168.123.123 example host) then one gets filtered in the Zywall port 80 firewall. I know this only because port 443 is open for administration interface and https://mydomain1.tld prompts for zywall login. So my conclusion is, that the LAN that accesses 111.111.111.111 in fact are routed to 192.168.1.1 whilst bypassing the NAT table. I need to know how to setup NAT / Policy Route, so that LAN WAN LAN will function with proper network translations instead of doing the 'quick nameserver lookup' or whatever this might be.

  • USB Device Not Recognized

    - by Franky Chanyau
    Ok this one gets a little bit complicated but bare with me :D A client brought her computer in to be fixed about a week ago, she says she tried charging a new phone she bought from china and immediately after her usb keyboard and mouse stopped working (typical). I had a quick look at it but because I did not have time, I did a simple system restore and it seemed as if the issue was fixed. I promptly sent it back to her but a few days back she called saying that the issue has returned. Turns out the computer was riddled with some virus that also corrupted her XP install so I had to format the whole thing(yes I tried repairing). I hoped that the format would fix the keyboard and mouse issue but the whole thing has escalated and the computer will throw the "USB Device not recognized" error when I plug anything into the many usb ports it has. I have installed all the drivers (including the chip set drivers) for the pc and even tried the unplugging from the power for a while trick, still no luck. I am sure it is not a hardware issue, but may be wrong. This is way over my head. Can anyone help? Computer: HP Compaq DC7100, Intel Pentium 4, 512mb RAM OS: Windows XP Professional SP2

  • USB 3.0 hard disk not detected on a particular host controller?

    - by Alvin Wong
    I have a USB 3.0 hard disk which has always been working on my desktop with an XHCI. Now I just bought a notebook with an XHCI (something with Intel's Ivy Bridge setup). The first time I plug the hard disk in its 3.0 port it is detected and working. A few hours later I try to connect it again, but seems that the notebook just ignored it! The light on the hard disk didn't blink as usual (instead it is hold at on). I then tested it with my desktop again and it is working perfectly. It gets trickier when I plug it in the USB 2.0 port of that notebook it is detected and working perfectly (despite the slower speed). Then I try to plug in an USB 2.0 USB flash drive to that USB 3.0 port, and it is detected (of course as USB 2.0). So, there are two USB 3.0 ports on my notebook's XHCI. Both of them are not working with my hard disk but working perfectly fine with my USB 2.0 UFD. What's wrong with it? When I plug in the hard disk, device manager doesn't change. I've tried re-installing the driver for the XHCI, but it changes nothing. Had I broke the USB 3.0-specific pins of both USB 3.0 ports?

  • Windows 7 x64 RTM USB Port Has Power But Won't Recognize Mouse/Keyboard/Anything

    - by ben
    I have an odd error that doesn't seem to fit in with any of the other odd Windows 7 x64 USB errors that have been kicked up on Google. Here we go: Uninstalled Tortoise SVN and clicked restart computer. My machine had been up for around 28 days On reboot my mouse and keyboard failed to work anymore, couldn't log in. Tried every USB port I have on my Dell 390 and the ports on my Dell 19's, nothing worked. They had power but Windows would not respond when I manipulated the keyboard/mouse. Rebooted my computer and pressed F2 to get into bios, my keyboard is working fine in bios. Keyboard and mouse work fine on other computers when using USB. Found adapters for keyboard and mouse to convert from USB to PS/2 ports, works fine. I'm actually typing this question on the same keyboard, same computer, just using PS/2 ports for my mouse and keyboard. It appears to be a Windows 7 x64 issue. Other things I have tried: Multiple other mice and keyboards, iphone, all with no luck. Each one gets power, but Windows never tries to install drivers or sees that they are connected. Uninstall and reinstall all USB drivers. Drives uninstall and reinstall fine and report no errors in Control Panel. In Power Management I disallow Windows from turning off USB ports to save power Installed the latest nVidia drivers for my graphics card, no change. Anyplace else I can look/try? Thanks!

  • ESXi 4.1 host not recognising existing VMFS datastore

    - by ThatGraemeGuy
    Existing setup: host1 and host2, ESX 4.0, 2 HBAs each. lun1 and lun2, 2 LUNs belonging to the same RAID set (my terminology might be sketchy here). This has been working just fine all along. I added host3, ESXi 4.1, 2 HBAs. If I view Configuration / Storage Adapters, I can see that both HBAs see both LUNs, but if I view Configuration / Storage, I only see 1 datastore. host1/2 can see both LUNs and I have VMs running on both too. I have rescanned, refreshed and even rebooted, but host3 refuses to acknowledge 1 of the datastores. Does anyone know what's going on? Update: I re-installed the host with ESX (not i) 4.0, same version as the existing hosts and it's still not recognising the vmfs. I think I'm going to SVmotion everything off that datastore then format it. Update2: I've created the LUN from scratch and the problem gets even weirder. I've presented the LUN to all 3 hosts, and I can see the LUN in the vSphere client's Configuration / Storage Adapters section on all 3 hosts. If I create a datastore on the LUN via the Configuration / Storage section on host1, it works fine and I can create an empty folder via datastore browser, but the datastore is not seen by the host2 and host3. I can use the Add Storage wizard on host2 and it will see the LUN. At this point the "VMFS Label" column has the label I gave with "(head)" appended. If I try the Add Storage wizard's "Keep the existing signature" option, it fails with an error "Cannot change the host configuration." and a dialog box that says 'Call "HostStorageSystem.ResolveMultipleUnresolvedVmfsVolumes" for object "storageSystem-17" on vCenter Server "vcenter.company.local" failed.' If I try the Add Storage wizard's "Assign a new signature" option on host2, it will complete and the VMFS label will have "snap-(hexnumber)-" prepended. At this point its also visible on host3, but not host1. I have a similar setup in a different datacenter which didn't give me all this trouble.

  • AD domain on web servers behind NAT - DNS issues?

    - by Ant
    I'm trying to setup an AD domain to manage the security between two Windows Server 2008 webservers that will sooner or later use NLB to balance website requests. I've hit a problem which I think is a simple solution and is down to DNS. My website domain is mydomain.com. The two servers are running behind a NAT firewall on the 10.0.0.0 IP range. I've setup the AD domain to be called ad.mydomain.com (as recommended by MS and a few other answers to questions on here). The second web server however doesn't want to join the domain, and gives an error pinning the problem on DNS - "ensure that the domain name is typed correctly" even though it queries the SRV record successfully and gets the correct DC back - dc.ad.mydomain.com. Doing a dcdiag /test:dns on the DC gives the Delegation error 'DNS Server dc.mydomain.com Missing glue A record'. I have a feeling I need to add something to the public DNS so that it in some way knows about ad.mydomain.com. Can anyone suggest whether I'm on the right track in adding something to the public DNS? Or whether it's something else? Many thanks

  • Automate creation of Windows startup script?

    - by Niten
    Is there a good way to automate installing local startup (rather than login) scripts in Windows XP and Windows 7, via the command line, WMI, or otherwise (even COM or Win32 if it comes to that)? I need to setup a local startup script on a large number of computers, and unfortunately, Active Directory is absolutely not an option. I would like to write a script or small program that I can run on each computer to perform the startup script installation in order to save myself a lot of error-prone point-and-click manual labor. I see that when one uses gpedit.msc to create a local startup script, information about the script gets stored in the registry here: HKLM\Software\Policies\Microsoft\Windows\System\Scripts\Startup However, if you create such a script and then delete its registry key, the script will remain listed in the local Group Policy editor; as is so often the case in Windows, apparently there is more going on there than meets the eye. This leads me to question whether it's safe to manually add subkeys for new startup scripts here (I wouldn't want my script to be overwritten by later changes made using the local Group Policy editor, for instance)... Another option that's occurred to me is to create an item in the Task Scheduler configured to run at system startup. However, my concerns there are twofold: Can this be automated any more easily? For instance, the at command doesn't appear to let you schedule a task for system startup, and WMI's Win32_ScheduledJob interface looks unreliable (it fails to show any of my currently scheduled tasks, for one thing). Would I be able to prevent users from logging in until the scheduled startup task is completed, as can be done with "normal" Windows startup scripts? Thanks in advance for any suggestions, I've been banging my head against this one for a bit...

  • Looking for suitable backup solution Mac OS X to offsite Centos 6 server 1TB of working data

    - by Brady
    I'll start by saying what we have in place currently: On site file server (Mac OS X Server) that is used by GFX designers and they have a working 1TB of data. Offsite server with 2TB available storage (Centos 6) Mac OS X server rsync data to offsite server every 6 hours (rsync -avz --delete --progress -e ssh ...) Mac OS X server does full data backup to LTO 4 tape on a 10 day recycle (Mon-Fri for 2 weeks) rsync pushes about 60GB of file changes a day. The problem: The onsite tape backup is failing as 1TB of graphics files don't compress well to fit onto a 800GB LTO4 tape. Backup is incredibly slow doing a full backup. Pain in the backside getting people to remember to change the tape. Often gets forgotten etc The quick solution: Buy LTO5 Drive and tapes. However this has been turned down because of the cost... What I would like: Something that works in the same way rysnc works. Only changed data is sent over the wire and can be scheduled to run multiple times during the day. Data that is sent is compressed and sent over SSH. Something that keeps a 14day retention but doesn't keep duplicate data So as an example if I have 1TB of working data and 60GB of changes are made each day then I expect around 1.84TB of data to be stored on the offsite server. To work with the Mac OS X server and Centos 6 server. Not cost an arm and a leg. Must be a cheaper solution than buying an LTO5 drive with tapes (around £1500). Be able to be setup to run autonomously. Have some sort of control panel that will allow an admin to easily restore a file/folder. Any recommendations?

  • File permissions question

    - by Matthew Robert Keable
    I just switched my site's server from Windows to Linux, and am finally able to control file permissions from my ftp. So, seeing that all permissions were 705 by default (and not wanting just anyone to have permission to execute), I went and changed everything to 744. Now, gif and jpg links don't work, pdf download links don't work, php links don't load, and mov files don't play. Conversely, all html files work perfectly. Setting things back doesn't seem to help. Even setting to 777 gets me nowhere. Any ideas on what might be going wrong? I've been googling file permissions all day (solved that problem with the Windows-Linux switch, which has bred a new problem), and I don't think anything I can find has escaped my attention. The site: absis-minas.com Go easy on a n00b. I took up learning php out of interest, and wound up delving into server management issues due to a very simple line of code not working the way it was supposed to. Thanks!

  • How to find the cause of locked user account in Windows AD domain

    - by Stephane
    After a recent incident with Outlook, I was wondering how I would most efficiently resolve the following problem: Assume a fairly typical small to medium sized AD infrastructure: several DCs, a number of internal servers and windows clients, several services using AD and LDAP for user authentication from within the DMZ (SMTP relay, VPN, Citrix, etc.) and several internal services all relying on AD for authentication (Exchange, SQL server, file and print servers, terminal services servers). You have full access to all systems but they are a bit too numerous (counting the clients) to check individually. Now assume that, for some unknown reason, one (or more) user account gets locked out due to password lockout policy every few minutes. What would be the best way to find the service/machine responsible for this ? Assuming the infrastructure is pure, standard Windows with no additional management tool and few changes from default is there any way the process of finding the cause of such lockout could be accelerated or improved ? What could be done to improve the resilient of the system against such an account lockout DOS ? Disabling account lockout is an obvious answer but then you run into the issue of users having way to easily exploitable passwords, even with complexity enforced.

  • Postfix with relayhost - relay access denied for bounces

    - by Alex
    I have set up a Postfix Mailserver, outgoing mail is being sent through a smarthost/relayhost which requires authentification. That works great, internal clients can send to foreign recipients though this relayhost. However, when an external mail for a local, non-existent user arrives at the server, postfix tries to send a non-delivery notification to the sender. This mail is also sent through the relayhost obviously, but it fails with error 554 5.7.1 : Relay access denied This gets logged to the mail.log: Nov 9 10:26:42 mail postfix/local[5051]: 6568CC1383: to=<[email protected]>, relay=local, delay=0.13, delays=0.02/0.02/0/0.09, dsn=5.1.1, status=bounced (unknown user: "test") Nov 9 10:26:42 mail postfix/cleanup[5045]: 85DF9BFECD: message-id=<[email protected]> Nov 9 10:26:42 mail postfix/qmgr[4912]: 85DF9BFECD: from=<>, size=3066, nrcpt=1 (queue active) Nov 9 10:26:42 mail postfix/bounce[5052]: 6568CC1383: sender non-delivery notification: 85DF9BFECD Nov 9 10:26:42 mail postfix/qmgr[4912]: 6568CC1383: removed Nov 9 10:26:43 mail postfix/smtp[5053]: 85DF9BFECD: to=<[email protected]>, relay=mail.provider.com[168.84.25.111]:587, delay=0.48, delays=0.02/0.01/0.26/0.18, dsn=5.7.1, status=bounced (host mail.provider.com[168.84.25.111] said: 554 5.7.1 <[email protected]>: Relay access denied (in reply to RCPT TO command)) Nov 9 10:26:43 mail postfix/qmgr[4912]: 85DF9BFECD: removed According to this error, I suppose that postfix does not login at the relayhost when sending those bounces. Why? Normal outgoing mail works just fine. This is how my main.cf looks like: http://pastebin.com/Uu1Dryxy And of course /etc/postfix/sasl_password contains the correct credentials for the relayhost. Thanks in advance!

  • Multiple threads stuck on Tomcat behind Apache mod_proxy

    - by Eddy
    we just took a break at butting our collective heads against this maddening problem we're having. Basically this brand new deployment of Tomcat 6.0.36 crawls down to a halt every couple minutes with many of the worker threads stuck as in the example snippet; only after a while the server gets "unstuck" for another couple minutes. The previous Tomcat works a charm though, but keeping it is not really an option... On netstat, we also see a lot of FIN_WAIT and FIN2_WAIT.

  • Moving Zend Framework 2 from apache to nginx

    - by Aleksander
    I would like to move site that uses Zend Framework 2 from Apache to Nginx. The problem is that site have 6 modules, and apache handles it by aliases defined in httpd-vhosts.conf, #httpd-vhosts.conf <VirtualHost _default_:443> ServerName localhost:443 Alias /develop/cpanel "C:/webapps/develop/mil_catele_cp/public" Alias /develop/docs/tech "C:/webapps/develop/mil_catele_tech_docs/public" Alias /develop/docs "C:/webapps/develop/mil_catele_docs/public" Alias /develop/auth "C:/webapps/develop/mil_catele_auth/public" Alias /develop "C:/webapps/develop/mil_web_dicom_viewer/public" DocumentRoot "C:/webapps/mil_catele_homepage" </VirtualHost> in httpd.conf DocumentRoot is set to C:/webapps. Sites are avialeble at for example localhost/develop/cpanel. Framework handles further routing. In Nginx I was able to make only one site available by specifing root C:/webapps/develop/mil_catele_tech_docs/public; in server block. It works only because docs module don't depend on auth like others, and site was at localhost/. In next attempt: root C:/webapps; location /develop/auth { root C:/webapps/develop/mil_catele_auth/public; try_files $uri $uri/ /develop/mil_catele_auth/public/index.php$is_args$args; } Now as I enter localhost/develop/cpanel it gets to correct index.php but can't find any resources (css,js files). I have no Idea why reference paths in browswer's GET requsts changed to https://localhost/css/bootstrap.css form https://localhost/develop/auth/css/bootstrap.css as it was on apache. This root directive seems not working. Nginx handles php by using fastCGI location ~ \.(php|phtml)?$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param APPLICATION_ENV production; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } I googled whole day, and found nothing usefull. Can someone help me make this configuration work like on Apache?

  • Two parts: linux startup script to connect to bluetooth and cron to keep it connected

    - by D.R.
    I have a mini bluetooth keyboard and a Raspberry Pi running a Debian-based distro. I know the MAC address of the keyboard but for this question, let's just use AA:BB:CC:DD:EE:FF. Right now I have to have a wired keyboard connected as well as my bluetooth dongle for the mini-keyboard and on the wired keyboard, I have to run the following when the device boots up: sudo hidd --connect AA:BB:CC:DD:EE:FF If the device goes idle for too long, then the bluetooth disconnects and I have to pull out my wired keyboard and retype that same command. What I'm looking for it a way to have that command run at startup and a way to sense if it gets disconnected so that it will auto reconnect. The annoying thing is that they keyboard has to be in pairing mode (even though it has already been paired) when I run that command, otherwise it tells me the host is down. So perhaps the script needs to prevent it from disconnecting due to inactivity, otherwise I'll have to put it back in pairing mode to reconnect. So to recap: - A script to connect at startup (I can make sure to put the keyboard into pairing mode before turning it on) - A script to prevent it from disconnecting (maybe some sort of signal to send to it every 60 seconds or something?) Any help with this is greatly appreciated! StackOverflow is always the best place to find answers to weird questions! I've been searching long and hard for an answer, but finally had to resort to coming here! Thanks!

  • Cross OS data recover question, USB drive involved.

    - by Moshe
    Here's the story: A MacBook had OS X 10.4 and Windows XP dual booting using rEFIt. Then the Windows partition gets corrupted and it won't boot. Presumably a virus. There were sensitive files there and those were successfully copied to a USB drive and then 10.5 was installed on the hard drive, formatting the drive in the process. The USB drive's contacts cracked and he data is lost from there, unless it can be resoldered. The issues is that there is too much solder there already. So, how can the data in question be recovered? The files were Microsoft Money (not the latest version) files for the Windows version of the program. Right now, only OS X is installed on the MacBook. Is there Mac based program that can recover the Windows data or am I better off trying to resolder the drive? Does anyone know how to best resolder a USB drive more than once, where the first solder is ther, but detached from the silicon? Also, what format (extension) are Microsoft Money files? In need of help!

  • Understanding NFS4 exports and pseudofilesystem

    - by Trevor Harrison
    I think I understand the way pre-NFS4 exports work, specifically the namespace of the exported point. (ie. export /mnt/blah on server, use mount server:/mnt/blah /my/mnt/point on client) However, I'm having a hard time wrapping my head around NFS4 exports. What I've been able to gather so far is that you export a 'root' by marking it with fsid=0, which you then import on the client side by referring to it as '/'. (ie. exportfs -o fsid=0 /mnt/blah on server, mount server:/ on client) However, after that, it gets a little weird. From my playing around, it seems I can't export anything else thats not under /mnt/blah. For example, exportfs /home/user1 fails when trying to mount from the client unless /mnt/blah/home/user1 exists on the server. If this is the case, what is the difference between exportfs /mnt/blah/subdir1 on server and mount server:/subdir1 on client and just skipping the exportfs and mounting whatever subdir of /mnt/blah you want? Why would you need to export anything other than the root? Its all in the same namespace anyway.

  • Storing changes to multiple databases in a single centralized database

    - by B4x
    The setup: multiple MySQL databases at different locations with the same scheme. The databases are in production. The motivation: we want to present information in these databases in a web interface, clearly showing which database the row originated from. We want to be able to get this data from one single source (for different reasons, one of them is pagination which gets tricky if you use multiple sources). The problem: how do we collect data from multiple databases, storing it at a central location and clearly marking the origin of each row? We have discussed using a centralized DB that tracks changes to the production DBs, with the same schema and one additional column for origin. If possible, we would like to avoid having to make changes in the production environment. Since we can't use MySQL's replication (multiple masters to a single slave isn't allowed), what are our other options? Are there any existing solutions for something like this or do we have to code something ourselves? Is the best solution to change the database schemas in production and add a column for origin? The idea of a centralized database isn't set in stone. If there is a solution to this that solves our other problems without a centralized DB, we can be flexible. Any help is much appreciated.

  • Dell Dimension 8400 Startup error

    - by Michael
    Hello all, thanks first for taking the time to read this and possibly help me...... now I am pretty decent of a computer tech...but not enough. I am having an issue with my computer which is running windows xp and as I mentioned it is a dell Dimension 8400. as soon as I power the system up the fan goes into hyper drive (spins like crazy and is very loud) then the start up screen with dell comes up and the loading bar gets stuck on the process of "Bios Revision A00" and never loads beyound that. I have read alot about it and think that the main problem was that it can not locate the file (which does have an updated version) I think it is A09. I can not enter safe mode, Bios mode or anything. I do have the file on my other computer and I was wondering if there is a way that I can use a usb flash drive (as I have read on other sites) to create a bootable MS-Dos diskette but I am failing at creating as such....is this possible? or is there anything else I can do? I tried to remove the battery from the system for about 10 minutes while it was completely unplug and tried then to reboot it and go into the bios menu but the same thing keeps happening....can anyone help me :-(

  • Inconsistent SMTP Access

    - by Mike Hanson
    I have a mail server setup on Windows Server 2008. All was working fine, until I wanted to map a drive on the server so that I can access files on another machine. Windows prompted me to configure Network Discovery, which I did with the "Home/Office" option rather than "Public". After that, several access points that worked before stopped working, like VNC, SMTP, etc. After reinstalling those packages, things appeared to be working again. Unfortunately, problems have returned with my SMTP server. I can use an web-based SMTP tester, and it connects in 62msec (as expected). However, if I telnet from my machine on the same LAN, it takes more than 20 seconds to connect! When I try to send messages from Outlook, it times out entirely with the message: Sending' reported error (0x80042109) : 'Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).' I've checked the firewall settings, I've tried configuring it to use port 587 instead of 25, but nothing gets around this problem. Does any have any useful insights? Thanks in advance!
