• Braces (syntax) highlighting in OpenOffice Math formula text editor

  - by Oleksandr Bolotov

  When you use OpenOffice Math, in upper part you see formula and formula text editor in lower part. Almost like this: %sigma = 2 %mu %epsilon + %lambda Tr(%epsilon)I So my questions are: How to replace OpenOffice Math's formula text editor with own text editor? ... or how to enable braces (syntax) highlighting in embedded editor? ... are there any extensions for anything like this? I need this because sometimes it's too much braces and stuff and it's hard to distinguish which braces match each other. Please do not suggest me to use MathType Mathematica (or anything) instead of OpenOffice Math (because I'm almost happy with it:)

• A design for watching IPTV anywhere in the house?

  - by Carlos

  I'm currently getting TV and internet via IP to my house. The service comes into an ISP-supplied Router (ST585) which is in turn connected to an IPTV box. I need to replace the router, as it's port forwarding seems to be broken, so I was thinking of getting a box with an IGMP proxy. I once mistakenly got a non-IGMP box, with the result that the internet worked, but the IPTV didn't. The trouble is, I have no idea how to set up the IPTV part of the installation. I do have a copy of the ST585 configuration, but it doesn't look anything like the Cisco stuff that I learned about at CCNA. What are the steps necessary to reproduce the IGMP setup? I was thinking of WireSharking the communications on the network, but I suppose I'd need a hub for that? As a bonus, since the packets are coming in with the TV signal, is it possible to mess with the IGMP setup so I can watch TV anywhere in the house?

• SQL Server 2012 and SQLMail - will it still work?

  - by Kharlos Dominguez

  We are considering upgrading our SQL Server, which is currently running 2005. We use SQLMail heavily in the organization, both to send e-mails and to import some into a database. I've read on various places that SQLMail was deprecated and superseded by "Database Mail". I'm confused because this MS page: http://msdn.microsoft.com/en-us/library/bb402904.aspx seems to imply that it would still work? I understand the dangers of SQLMail but we do not have the resources to rewrite the scripts right now and would prefer to do it later on. Does SQLMail still work in 2012, and if not, how easy is it to replace with Database Mail, both for reading and sending e-mails?

• Do two portforward rules translate to "and"?

  - by blsub6

  I just set up an Exchange server to replace my DeskNow mail server. I want to start testing my internet mail exchange of my Exchange server. I can only set the MX records on my DNS up to my one external IP address so I was thinking that I could set up a firewall rule on my internet-facing firewall that port forwarded the smtp packets to two different servers. My question is: If I do that, will that mean that the smtp packets will be forwarded to just the first internal IP on the list? Or does it mean that the packet will be cloned and sent to both IPs?

• PC boots on then off & 30 sec. later on again, it wiil shut off on itself mostly in idle or just unexpecticly

  - by Jody

  This problem started w/ my sons desktop, it would just shut off after a bit of work or stay on for a long time & to get it to unfreeze is to cold boot it, i put a new HDD in & I still have the same issue, RAM is good power supply fan is moving quite as well as all the rest of the fans it has stayed fairly dust free, i'm at a loss ,I have defaulted all the factory settings changed battery & ungraded to a new OS. I still have the same problem. the power light stays on after it has shut down & when upon starting it goes straight to safe mode option page, I start in last good config. reboots again takes 30 sec. to boot & will work again for a while, the only other thing I haven't tried was a graphic card replace, i'm onboard video now & have been.

• Run non-interactive script in single user mode

  - by Jed Daniels

  Is it possible to run a "startup" script when booting into single user mode? I need to be able to boot into single user mode, run my script, then reboot into multiuser mode without any human interaction. I've done a bunch of research and can't find anything that is clear on the topic, although of course I could replace something else that does run with a wrapper that also launches my script, but I'd prefer to do it in some official way. Ideally, the solution will work in FreeBSD 6 and up, but I'm willing to accept only new versions if it just doesn't exist in the older revs.

• Microsoft Natural Keyboard 4000, more problematic keys?

  - by Saebin

  So my new motherboard doesn't have a ps/2 connector, so I bought a Microsoft natural keyboard 4000 to replace my old natural keyboard. But, some of the keys stopped working, so I bought another 4000... which then had different keys stop working. I tried cleaning them out, but no go. My guess is some condensation or something fell on it and shorted it out... but if it is that easy to short out, I can't imagine how my old keyboard lasted for years. Did I just get unlucky or are newer keyboards more vulnerable? Any recommendations?

• Port forwarding on D-Link DIR-615 super-slow, useless

  - by Jaroslav Záruba

  Hello I have replaced my old router with DIR-615 from D-Link, and now the port forwarding is so slow it makes the router practically useless. Accessing the router itself (admin UI) is without issues, no delay whatsoever. But when I try to access a service on another computer in the network the requests take minutes and minutes. (E.g. I can see source of my GWT-app main page, but loading additional CSS and JS files takes years.) If anyone could recommend any further diagnostics I should do to figure out what is happening it would be great. Few notes: happens with more services (web-app on Tomcat, viewing directory index via Apache) it does not make a difference whether the service is hosted on wired or wireless PC accessing the service on a localhost works fine turning off firewall on the target PC does not make difference either (makes sense) when I replace this router with the old one (both 192.168.1.1) everything works fine I see nothing suspicious in the router's log I believe I have the latest firmware (4.11) DIR-615 sucks, it already died once completely Regards Jarda Z.

• How can I edit files directly from find results

  - by Sergio Tulentsev

  Let's say, I want to replace one string with another. Normally I use TextMate, but today, I don't remember why, I decided to run the search in Sublime Text 2 (which I installed some time ago, but haven't used since). I was impressed with "Find Results" window, seems more useful that textmate's. Then I tried to edit text right inside that window and (I can swear on my macbook) it worked (I was able to commit those changes to git repo)! I thought then, "Wow, that's a really nice feature. Should I migrate from TM already?". Unfortunately, I wasn't able to reproduce this behaviour later. I can still edit text in "find results" window, but changes don't persist (that is, original files are not touched). Am I doing something wrong now, or was it caffeine-induced hallucination earlier in the day?

• How would you diagnose an integrated network card that doesn't show up on the device list?

  - by Tomer Gabel

  I've been setting up a server based around a Gigabyte GA-G33M-DS2R motherboard (G33, PCH9R with integrated Realtek 811B network device. I've enabled it in the BIOS, but it doesn't show up in the pre-boot PCI device list, isn't recognized by Windows (even after installing the chipset and networking drivers) and doesn't even show up via lspci. I've tried cycling power, disabling, cycling again, enabling, cycling again etc. to no avail. I'm sort of at a loss at this point; the board isn't under warranty anymore, but I'd rather not have to replace it. Any advice would be greatly appreciated...

• what's the difference between /etc/init.d/sshd start and /usr/sbin/sshd?

  - by jasono

  I'm having issues with passwordless ssh. I've checked, double checked and checked again that I have everything set up correctly. Both machines are RHEL6 and when the destination machine first boots up passwordless ssh does not work. If I stop ssh (service sshd stop or /ect/init.d/sshd stop) and then start it directly (/usr/sbin/sshd) passwordless ssh works fine. If I start ssh via the service (service sshd start or /etc/init.d/sshd start) passwordless ssh does not work. Just for testing I've tried commenting out the entire start() function in /etc/init.d/sshd and replace it with /usr/sbin/sshd - that still fails to allow passwordless ssh. I believe that this means that something in the /etc/init.d/sshd file is causing the screw up but I don't know enough about linux to narrow the issue down.

• Completely replacing (upgrading) a RAID 5 array of disks on an ESXi server

  - by jshin47

  I have a development server that runs several VM on ESXi 5. It has an array of disks in the RAID 5 configuration where all of the disks are currently the same size. I would like to expand storage on this box greatly, but I am not sure what the smartest way to go about this would be. My current plan is to: Turn off all VM Copy VM folders from server to another location Verify that I can mount all the VM on the new location (ie that the copy went ok) Replace all the disks with new, bigger ones Reinstall ESXi5 Copy the VM back over This seems like it might take a while to accomplish and is not terribly slick, especially since I will have to reconfigure ESXi 5, but is there a smarter alternative?

• How to copy Netscape email

  - by Olav

  I think I have the Netscape mail-directory from old computer, how do I copy it to new computer? (Netscape 7.1 Mail, Thunderbird or Seamonkey). I think I have the files in Olduserbackup\xjuwtwtb.slt\Mail I create a new mail account with server pop.superuser.com, and find a directory with that name in C:\Users\myusername\AppData\Roaming\Mozilla\Profiles\default\ou6umlif.slt\Mail I replace the files with those from the backup, but Netscape still shows pop.superuser.com in its interface. Is there some kind of registry setting somewhere I will have to change?

• Is it possible to clone system drive in Windows 7?

  - by Ladislav Mrnka

  My current problem is that my Window 7 system drive is unstable. I would like to try to clone this drive to the same type of disk (OCZ Vertex 2 120GB to OCZ Vertex 2 120GB) and replace the system drive with created clone. My installation doesn't have ProgramData and User profiles on the system drive. Later on (after warranty replacement of problematic drive), I would like to copy ProgramData and User profiles to different disk (Samsung SpinPoint 750GB to OCZ Vertex 2 120GB) and use the new disk instead. Note: data have only few GBs so there should not be any problem with the disk size. Is it possible? What is the best way to do that? Is it better to simply reinstall the system from scratch (I would like to avoid it)?

• Apache Upgrade Version

  - by mcondiff

  I have a live server that I need to upgrade Apache from 2.2.10 to 2.2.15 on Windows Server 2003. I have just inherited this server and need the fastest way to upgrade to the latest stable version without much downtime and without messing up my configuration. My first thought is to copy the httpd.conf, uninstall the current Apache, install the latest stable Apache version and then replace the httpd.conf with the previous live version. Anyone see a problem or pitfall with that? How does a Server Pro do something like this. (I'm a programmer and am new to server systems administration).

• How to set up Asus RT-N66U in bridge mode with wired connection to main router?

  - by Milligan

  I have a wired router (TP-Link RT-860) in the basement where the cable service comes in. Eight wired ethernet connections span two buildings. I currently have a Linksys wireless router set up in bridge mode, but its signal doesn't span the whole area. I have purchased an Asus RT-N66U to replace it, but I can't figure out how to set it up in bridge mode. Does anyone know if this is possible? Second question: Would there be any advantage in installing DD-WRT on the Asus?

• Using a second wifi router as a wireless bridge

  - by Greg-J

  I purchased a D-Link DGL-4500 to replace my aging WRT54G around a year ago, only to find it nowhere near as reliable. It's been collecting dust since. I'm wondering if there is a way to use it as a wireless bridge so I can connect it to my home network and then use it's ethernet ports to provide network access to several devices. Is this something that can be done? If not, are there devices meant for this? Any help would be appreciated.

• How to send Bluetooth audio to non-Bluetooth speakers?

  - by wonsungi

  In short, I am looking for a Bluetooth-3.5 mini stereo converter. What is this type of device called, and what are some of the best models (is there a difference in audio quality/lag)? I wish to connect some speakers (Altec Lansing inMotion IM7), which does not support Bluetooth, to my laptop (Lenovo X301) wirelessly. Currently, I can connect my laptop's headphone jack to the AUX jack on my speakers via a mini stereo cable. How do I replace this cable with some type of Bluetooth setup? I am not sure what this Bluetooth device is called. I thought I found something, but it actually does the opposite of what I need (3.5 mini stereo-Bluetooth). (My OS is Vista Enterprise, if that matters)

• Mini-jack problem with Sony Vaio (running XP)

  - by qftme

  I have a five year old Sony Vaio laptop (vgn-fw31m) that has had impact damage to the audio-output mini-jack for about the last year or so. In a recent discussion with my brother, we wondered whether it would be possible to write a program that would enable windows to use the microphone mini-jack input as the audio-output? As I currently use this laptop for work I am not keen to risk pulling it apart in order to replace the components comprising the audio-out. I therefore 'hope' that a programming solution exists. I would really appreciate any advice on this and eagerly await your response. Kind regards, qftme :)

• Should I limit end-user gigabit ports to avoid saturating uplink/trunk connections?

  - by Joel Coel

  We have a campus with 16 buildings and older 850nm 1Gbps fiber links between the buildings, that all come to a core switch for our servers that also uses 1Gbps ports. We're finally starting to replace our aging 10/100 end-user switches, and much of what we're looking at are 1 Gbps units. My question is, since the trunk/uplink lines are still 1Gbps, if I were to install 1 Gbps switches for end users, should I limit the ports to 100Mbps until I can also upgrade the trunks to avoid allowing a bad-behaving host to saturate a trunk line (since we're a college, we have plenty of mis-behaving hosts) and thereby create a DoS situation for a building, or will TCP congestion control typically take care of that for me? What if we have a lot of UDP traffic (games, video chats, even a small amount of bittorrent)?

• Misbehaving Network Printers - options?

  - by Dan Kelly

  We are having some issue with printers on our network. We have 3 floors, 2 printers per floor (A3 & A4) all connected to the same Print Server. The issue is that the same printer may not behave the same on two different, seemingly identical desktops. The commonest place this is seen on our bulk print script in AutoCAD - occasionally drawings may print Landscape on Portrait paper, despite drawings always being Landscape... Does any one have any suggestions on what we can check / try? The current line of attack is to setup a new Print Server, with the HP universal print driver rather than the device specific drivers, and replace printers using exactly the same method on all desktops. Sound good?

• Workflow Automation software for SVN

  - by KyleMit

  We're currently using IBM's ClearQuest for task management and ClearCase for change management. They plug and play very well with each other. Users can create tasks in ClearCase as defects and enhancements, and developers can use those tasks to check out and modify code in source control. We're looking to upgrade to a better, more modern Source Control system, like SVN, although we're not married to that as our Source Control system. There are loads of source control systems out there, but I'm having difficulty finding one that also includes the ability to have users enter tasks and track them, especially in a native way to the source control system itself. Are there any products that replace ClearQuest for systems like SVN? Are there any other cheap / open source application pairs that handle both sides of the coin?
