• Ubuntu 10.04 not detecting multiple monitors

  - by razass

  I have 2 graphics cards, the output from the lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850] 02:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4350] I have one monitor connected to the 4850 and 2 connected to the 4350. However when I go into System Preferences Monitors the only monitor shown is the one connected to the 4850. Is there something I need to enable for it to be able to use the other card? How do I get this to work. Thanks.

• Disk quota problem in Windows Server SBS 2003

  - by deddebme

  I have got a new job and the existing SBS 2003 domain setup is unsecure (i.e. everyone is a domain admin etc etc). There are lots of problem due to inexperienced "network admin", and I am trying to fix them one by one. There exist one issue which I found quite weird, that the "Quota" tab exists in the C:(NTFS) drive but not the D:(NTFS) drive. I played around with gpedit to enable disk quota (it was "not configured" before), but still I can't see that tab. Have you seen this problem before? How did you solve it?

• Mac OS X 10.5/6, authenticate against by NIS or LDAP when both servers have your username

  - by Wang

  We have an organization-wide LDAP server and a department-only NIS server. Many users have accounts with the same name on both servers. Is there any way to get Leopard/Snow Leopard machines to query one server, and then the other, and let the user log in if his username/password combination matches at least one record? I can get either NIS authentication or LDAP authentication. I can even enable both, with LDAP set as higher priority, and authenticate using the name and password listed on the LDAP server. However, in the last case, if I set the LDAP domain as higher-priority in Directory Utility's search path and then provide the username/password pair listed in the NIS record, then my login is rejected even though the NIS server would accept it. Is there any way to make the OS check the rest of the search path after it finds the username?

• ASA 5505 Vlan question

  I am setting up a cisco asa 5505 with the base license. I can communicate from inside-outside, outside-inside, inside-home, which is my desired traffic security.

• Can I send HTML mails in Outlook Web Access?

  - by Mestika

  Hi, In my organization some of the employees are located elsewhere from headquarter and therefore they are using the Outlook Web Access (OWA) to receive and send E-mails. The problem lies in the format in how E-mails are sending and forwarded. When receiving an E-mail which has HTML context (e.g. tables) it shows it right enough but when the same E-mail is forwarded it completely disturb the layout and it seems like it only can send in pure text. Is there any way I can enable HTML to me used for sending and forwarding E-mails through OWA, either via the settings in the OWA or our Exchange server? Thanks Sincerely Mestika

• Belkin Wireless G router not working on Windows 7

  - by coore

  I have a Belkin F5D7230-4 Wireless G router which used to work on XP. I have a clean Windows 7 install (on the same desktop PC), and it just won't work. Device Manager lists the adapter as a USB device, but it says "The drivers for this device are not installed", even though the driver installer said the installation was OK. Manage Wiresless Networks says "wireless is not currently enabled". The WLAN AutoConfig service is running. My specific question is which of the two symptoms above should I go for first? Should I try to fix the driver installation somehow, or should I try to enable wireless? Is one caused by the other, or is this two independent problems? Any other thoughs that could help me are also appreciated.

• 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:)

• Where should I plug in my monitor -- Motherboard or Graphics card?

  - by Jeremy White

  Assuming I am using the following equipment... motherboard with HDMI/DVI & no embedded graphics discrete graphics card (nVidia or ATI) on PCI-E slot Intel CPU with integrated graphics ...where should I plug my monitor into the computer? Presumably, I'll get the fastest speed on games connected directly to the graphics card. But there is also power savings when connecting to the motherboard and accessing the Intel on-board graphics. I've read that some motherboards can switch automatically between the Intel graphics and discrete graphics. Is that something that works well, and where do I connect the monitor to enable that?

• Outlook - Sychronise contacts from exchange

  - by THEMike

  At work the exchange server has details of all employees in the system. Then there is the Contacts folder in Outlook. I can populate this with all staff, but, I want to synchronise it against all staff (occasionally) removing people who in are in my local contacts, but not in the Exchange server (leavers) and importing changes/updates/new staff from the exchange server. However, I also have some personal contacts (family members etc) locally that I want to exclude from that. This is to enable synching to my smartphone better. Any suggestions? Regards, Michael

• mysql single database relocation

  - by asdmin

  I would like to know if it's possible to operate different databases on different filesystem locations. Background: we are a hosting service, which hosts mysql, web, and smtp to it's customer, but all our services (sql, smtp, http) are located in a different place. We are going to assign a single logical volume to a customer, which will accommodate the customer's mailing, weppages and (hopefully) sql database. Web pages and mailing are already covered, but I am not able to find a configuration setting which would enable me to specify the location of a database (the directory where mysql stores the DB). Let me please highlight, the target here is to relocate different databases to different locations in the filesystem, not moving them from a single place to an another (single) place. Also please do not bother answering with soft and hard symbolic links. ;) Thanks

• Multiple servers using same nameservers

  - by Robsimm

  I have 2x servers with the following OS's and Control Panels: Windows Server 2003 running Plesk 9 Centos 5.3 running WHM/cPanel The Windows server 2003 server is hosting the two nameservers: ns1.domain.com ns2.domain.com I have BIND running on the Centos 5.3 server, but I wish for my customers to use the same nameservers ns1.domain.com and ns2.domain.com (as per the Windows Server 2003 server). My first question is - is this possible? And if so, how would I go about configuring both servers to enable such a configuration? Thanks very much.

• No recent docs listed in Office 2007 on Windows XP Pro

  - by user58094

  Hi, I have Office 2007 installed on a laptop running Windows XP Pro. When I go to open a file in Excel or Word, there is no list of recent documents. On the Options/Advanced page, the "show this number of recent documents" spinner displays 0 but is grayed out so I can't change it. The help page it directs me to describes how to disable the list, but not how to enable it. In Word, it says something about the list being disallowed by Group Policy, but I am not part of any workgroup and, as far as I know, the policies are all uninitialized, so it should be allowed by default. There are recent files listed in MRU keys in the registry. A similar question has been answered, but I believe that only applies to Windows Vista or 7 because the folder mentioned doesn't exist on my system. Instead, the folder "%APPDATA%\Microsoft\Office\Recent" contains shortcuts to recent docs for both Excel and Word. Any other ideas? Thanks.

• Not able to connect to internet in RHEL 5

  - by chankey007

  I just installed red hat enterprise 5 in my laptop and on desktop both. In desktop it is working fine but in laptop it is not showing the eth device. (I tried ifconfig only lo is there). I tried ifup eth0 still nothing happened. The network service in /etc/sysconfig/network-scripts/ifcfg-eth0 and in /etc/sysconfig/network are enable. I had ubuntu in my laptop before and I faced same problem with that too. Is there any problem with my laptop? I have my system on dual boot and in win7 networking is running fine. I am not able to connect to the internet only, other devices are working fine. System conf: Sony vaio E series. 3 GB RAM, intel core i3 2.13 GHZ.

• Do I need to disable access to a publisher database when setting up SQL Server 2000 Transactional Re

  - by Kev

  I have a production database i.e. where there are constant updates and I've configured this to be published to another server using Transactional Replication. When I configure transactional replication I've been doing the following: disable access to the source database backup source DB then restore to subscription server configure replication re-enable DB access to our apps The problem with this approach is scheduling in downtime, having to suspend all the various timed scheduled tasks we run and shutting down access to our various applications that are dependant on this database. Can I just configure transactional replication without disabling access to the publishing database and the subscriber database will correctly catch up? i.e. are all the DML statements queued on the publisher and as soon as the subscriber is ready they are picked off and executed?

• Cisco VPN Client on Vista - Virtual Adapter

  - by ScaleOvenStove

  I have used the Cisco VPN client for years, and on XP it is pretty much rock solid, on Vista, not so much. You might be able to connect, but unless you set up a constant ping to something, it usually will disconnect, with this error: Reason 442: Failed to enable Virtual Adapater Now, most sysadmins will say, update you client - yes, I know, it hasnt mitigated the issue, ever. I have been using it on Vista since it came out, and updated my client every time a new update comes out. I have used it where the VPN server was a Cisco PIX and a Windows Box allowing the Cisco Client to connect. Anyone have any fixes that you can do on your client to fix this issue?

• Network card dies when trying to wake up laptop from sleep

  - by Bugmaster

  I have a Dell XPS 1640 laptop (aka Dell Studio XPS 16), running Vista. Whenever the laptop wakes up from sleep, my Broadcomm LAN card immediately dies. Any attempt to access it completely locks up whichever program I use to access it. There appears to be no way to re-awaken the card, other than rebooting; note that Vista does not even shut down properly if some program is waiting for the card. So far, I have tried the following: Disabled the "allow your computer to shut down this device to save power" in the device properties. This had no effect. Attempted to disable and then enable the card in the device properties. No effect. Tried ipconfig /renew: this locks up ipconfig to the point where I can't even kill its process. Force-install updated drivers from broadcomm: no effect. Does anyone have any other ideas ?

• How useful is mounting /tmp noexec?

  - by Novelocrat

  Many people (including the Securing Debian Manual) recommend mounting /tmp with the noexec,nodev,nosuid set of options. This is generally presented as one element of a 'defense-in-depth' strategy, by preventing the escalation of an attack that lets someone write a file, or an attack by a user with a legitimate account but no other writable space. Over time, however, I've encountered arguments (most prominently by Debian/Ubuntu Developer Colin Watson) that noexec is a useless measure, for a couple potential reasons: The user can run /lib/ld-linux.so <binary> in an attempt to get the same effect. The user can still run system-provided interpreters on scripts that can't be run directly Given these arguments, the potential need for more configuration (e.g. debconf likes an executable temporary directory), and the potential loss of convenience, is this a worthwhile security measure? What other holes do you know of that enable circumvention?

• Why does m4 error "linux-gnu.m4 - No such file or directory" appear the first time after updating sendmail.mc?

  - by Mike B

  SendMail 8.14.x | CentOS 5.x I've noticed that if I manually update /etc/mail/sendmail.mc (for example, enable TLS support), and then bounce sendmail, I get the following error: Shutting down sm-client: [ OK ] Shutting down sendmail: [ OK ] Starting sendmail: sendmail.mc:18: m4: cannot open `/usr/share/sendmail-cf/ostype/linux-gnu.mf': No such file or directory [ OK ] Starting sm-client: [ OK ] This only happens one time after I update a sendmail.mc file. If I bounce sendmail again (without making any other change), I don't see the error any more. Any idea why this happens? It doesn't cause any errors - I'm just curious.

• Training a spam filter based on Mailman moderator's actions?

  - by mc0e

  I'm planning a Mailman server, and looking for a good way to enable list moderators train a spam filter (likely to be either spamassassin or dspam). Has anyone come up with a good way to run training based on list moderator's decisions? Currently I don't have any better strategies than asking list moderators to forward spams one by one to a training address, which seems laborious and most likely to be inconsistently applied. Any ideas? I am aware of https://bugs.launchpad.net/mailman/+bug/558292 . I'm hoping someone has a better approach.

• SSL Certificate for local web server

  - by Firefly

  Is it at all possible to create a self-signed certificate for use on multiple machines on a local network which would stop the browser complaining it is not a trusted site? We have a product which is basically a computer running lighttpd to serve a web interface for configuring the computer (sort of how a router has a web interface). There can also be many of these machines running on the same network with dynamic IP's. What I basically want to do is enable SSL for extra security but I don't want people who are on the local network to be given a browser warning about the certificate not being trusted. Is this at all possible?

• IIS site not resolved by DNS server

  - by Alexio

  I've a problem with my network. My Config: SVR01 (ws2008r2): DNS server and Domain Server SVR02 (ws2008r2): IIS (v7.5) Domain Clients In SVR02 there are many sites. When I try to connect on one site (such as: demo1.myhomesite.intra) the browser say "Internet Explor can not display the webpage". Well... In this case I found a workaround: unplug and plug the lan cable (or disable and enable wifi) in my client and the site work correctly. But this workaround is not a solution. Please, can you help me??

• IIS 7 throws 401 responses on application whose physical directory has been shared

  - by tonyellard

  I have an IIS 7, Windows Server 2008 R2 box with a relatively fresh install. I've deployed a .NET 2.0 application using windows autentication to the server, and from the default website, added it as an application. I updated the IIS authentication to enable Windows Authentication. When I went to share out the physical directory for the application so that a developer could deploy updates, the users began to receive 401 errors. I can reliably recreate the issue by sharing out the directory of any newly created application. The IIS user has the necessary read/write access to the directory. What do I need to do to keep web users from receiving 401's while at the same time allowing this developer to have access to the physical directory for deployments? Thanks in advance!
