• How can I switch between the HDMI and DVI outputs of my graphics card?

  - by Owen Melbourne

  I've got an Nvidia GTX 560ti card which currently I've got my 2 monitors hooked up to using the 2 DVI ports. However its got a mini-HDMI port which I've plugged a HDMI cable in (with mini adapter) and lead it into my TV which is across the room. I'm hoping to be able to toggle between the HDMI output and the DVI outputs, however I'm not sure how I'd go about this, Could somebody please point me in the right direction, I'm not really worried about having all 3 on at the same time so that isn't a problem, but if its possible then I'll do that.

• esxi VM will not connect to virual switch

  - by NitroxDM

  I have a exsi box with a VM (Windows 2003) that will not connect to any of the switches. The switch shows the VM connected but I can not ping anything on the network. I have double checked the VM's IP. No dice. There are a ton of messages in the log: [DATE 'VmMisc' NNNNN warning] Failed to validate VM IP address: unknown Update: There are 3 other VMs. Each vSwitch has 56 ports. I can ping from one nic to the other. Each vSwitch shows that the new VM is connect. VMware ESX Server 3i V 3.5.9 Build 123629 Update 2: Out of the blue it just started working. I didn't change anything. I think it has something to do with RRAS.

• postfix specify limited relay domain while allowing sasl-auth relay

  - by tylerl

  I'm trying to set up postfix to allow relaying under a limited set of conditions: The destination domain is one of a pre-defined list -or- The client successfully logs in Here's the relevant bits o' config: smtpd_sasl_auth_enable=yes relay_domains=example.com smtpd_recipient_restrictions=permit_auth_destination,reject_unauth_destination smtpd_client_restrictions=permit_sasl_authenticated,reject The problem is that it requires that BOTH restrictions be satisfied, rather than either-or. Which is to say, it only allows relaying if the client is authenticated AND the recipient domain is @example.com. Instead, I need it to allow relaying if either one of the requirements is satisfied. How do I do this without resorting to running SMTP on two separate ports with different rules? Note: The context is an outbound-use-only (bound to 127.0.0.1) MTA on a shared web server which all site owners are allowed to relay mail to one of the "owned" domains (not server-local, though), and for which a limited set of "trusted" site owners are allowed to relay mail without restriction provided they have a valid SMTP login.

• Syn_Recievd on port 80 , IIS 7.5

  - by Ashian

  Hi I have a trouble on my windows 2008 server. I host several web site on it. From some days ago, my web sites stop responding on port 80 after a while. In this time I can't access web sites from local machine and from remote. I can also browse websites on other ports ( custom port that I set) I find that I have many Syn_Received status on netstat. And when web sites stop, I got only syn_received on port 80. I have to restart server because when I try to restart IIS , it takes a long time to stop W3SVC and many times it doesn’t stop at all. Would anyone please tell me : - How can I manage Syn Attack ? Thanks

• Securing a Windows Server 2008 R2 Public Web Server

  - by Denny Ferrassoli

  I'm setting up a public web server: Windows Server 2008 R2, IIS7.5. Does anyone have a tutorial / walkthrough / tips on properly securing a public web server? I've seen a few tutorials but mostly focused on Windows Server 2003. What I've done so far: Created a specific user account for the website / app pool, Renamed Admin account, Installed FTPS, Configured firewall to block any non-public service (web / https), Configured firewall to allow access to management interfaces only from specific IP addresses (rdp, IIS management, ftp) Maybe a few other things but can't remember at the moment... ICMP is allowed... Should I disable all except ping? Port scan reveals only web and https ports. Any other suggestions? Thanks

• Sharing my broadband connection over a router

  - by user1004985

  I have a broadband connection which I can connect to my laptop's ethernet port. If I want to use the same connection on another machine I would have to do it via a router (I dont want to use ICS since it requires both machines to be ON). I have a router but its uplink is a 4p4c pin rather that an 8p8c(RJ45) so my broadband cable wont fit into it. The router I have is ZTE ZXDSL 531B. And the broadband connection I am talking about has an antenna on the rooftop from which an ethernet cable (CAT 5) runs to my PC's LAN port. Is there some way of utilising the LAN ports of the router to achieve what I mentioned above. Please Help

• FreeBSD 8.2 + Apache 2.2 + mod_auth_pam2: unable to authenticate

  - by zneak

  I've installed Apache 2.2 and mod_auth_pam2 from ports, but I can't get local UNIX authentication to work. When I access the protected part of my local website, I do get the authentication request, and with pam_permit.so, it works. However, when I change pam_permit.so to the real thing, pam_unix.so, I get this message in httpd-error.log: [error] PAM: user 'foo' - not authenticated: authentication error This is the relevant part of my Apache config, though I don't think it's the problem as it works with pam_permit.so: <Location /foo> AuthBasicAuthoritative Off AuthPAM_Enabled on AuthPAM_FallThrough off AuthType Basic AuthName "Secret place" Require valid-user </Location> This is my /etc/pam.d/httpd, though I don't think it's the problem either, since it works with pam_permit.so: auth required pam_unix.so account required pam_unix.so So what am I missing? What does it take to have pam_unix.so work for httpd under FreeBSD?

• How to DNAT to different local IP based on what public IP was accessed with Shorewall?

  - by mikl

  My server has several public IPs, and is running a bunch of virtual machines with private IP adresses. As an example, I want to map ports 80, 443 and 8080 on 232.21.23.23 (public) to 192.168.122.12 (private). I have tried a couple of different NAT mappings, but none of them seem to work: # This doesn't work. DNAT net loc:192.168.122.12 tcp 80,443,8080 - 232.21.23.23 # Neither does this. DNAT $FW loc:192.168.122.12 tcp 80,443,8080 - 232.21.23.23 # Nor this. DNAT net:232.21.23.23 loc:192.168.122.12 tcp 80,443,8080 # I have no idea what I'm doing. DNAT $FW:232.21.23.23 loc:192.168.122.12 tcp 80,443,8080 Can anyone point me in the right direction?

• Port binding conflicts with "switch user" on Windows 7

  - by C-dizzle

  We are using the switch user function within Windows 7 under an active directory network. We have one application in particular that gives us an error: Only one usage of each socket address (protocol/network address/port) is normally permitted. bind Port 10001 Are there any other ports that can only be used at one time that might have an adverse effect on the other user? We try to mentor our users to use the log off function instead of switch user, but that doesn't always happen. As an alternative, is it possible to disable the 'switch user' button on our machines?

• VPN authentication and MAC addresses

  - by zakk

  I have to set up a VPN (various clients connecting to a web service on a server, which is also the VPN server) and I want to make sure that no user will share his/her credentials with third parties. I know that this problem is not solvable completely, but I'd want to set up some additional security checks... Some idea I have: 1) An additional check on MAC address, but... are MAC addresses preserved thru VPN? 2) Some kind of extra identification of the client (User Agent, open ports, I want to make sure that is the very same client I authorized). 3) I would like to avoid commercial solutions like a security token... I realize it would be the perfect solution, but it will be to expensive, I suppose... Do you feel that these options are viable? Do you have any other ideas? Thanks in advance for your replies!

• Connect iPad to windows 7 VPN

  - by Linuz

  My iPad keeps spitting out the error: "A connection could not be established to the PPP server." I am trying to connect it to a VPN I set up with Windows 7 as an incoming connection. On the iPad, I went into the VPN settings, added a new PPTP VPN with the following information Server: Windows 7 Computer's IP RSA SecurID: OFF Account: Account Username Password: Account Password Encryption Level: Auto Send All Traffic: ON Proxy: Off Now I know that it is making some connection to the Windows 7 Computer because whenever I intentionally put in the wrong VPN password on the iPad, it makes me put in the correct one before trying to connect again. All the ports are forwarded on my router for PPTP, and my Windows 7 Firewall is even off to try to get this to work. Any help would be greatly appreciated, thanks.

• Is it common to have portable hard drive not recognize?

  - by lamwaiman1988

  I have a bad hard drive which could not be recognized by windows. If windows can recognize it, it could just be pure luck. There are better chance of it being recognize by plugging it at the usb back of the machine, rather than the front one. More interestingly, I have a usb cable which fork itself at one side ( i.e it has 2 heads at one side ). I can plug both heads to the machine and connect the portable hard drive on the other end of the usb cable? Can I get more voltage by doing this? I am guessing the front usb port doesn't have enough power. I am wondering if I buy a new portable usb hard drive, would it have easy read by plugging at the front usb port? I am not sure if I screw up the jumper connecting the front usb ports, but it is okay for other device such as usb stick and mouse.

• Windows Vista to Windows 7 Gbit LAN slow file copy

  - by ashgromnies

  I have two computers with gigabit LAN, one running Windows 7 and the other running Vista. I have a D-Link DIR-655 router, with gigabit LAN ports. I created a shared directory on the Vista computer, mapped it as a network drive on the Win 7 computer, and tried copying a 2 GB file... and it's going at 900 KB/s Yep... 900 kilobytes per second, about 7 Mb/s. Why so slow? Any ideas?

• please explain my fio results - is O_SYNC|O_DIRECT misbehaving on linux?

  - by Zoltan

  I'm going mad over figuring out what the problem could be with one of our storage boxes. With a simple fio script I'm testing random writes using bs=1M and direct=1. The SSD is a Samsung 840pro attached to an LSI HBA (3Gbit/s ports). This is the result I'm getting under FreeBSD 9.1: WRITE: io=13169MB, aggrb=224743KB/s, minb=224743KB/s, maxb=224743KB/s, mint=60002msec, maxt=60002msec This is regardless of sync being set to 0 or 1. On linux, this is the result with sync=0: WRITE: io=14828MB, aggrb=253060KB/s, minb=253060KB/s, maxb=253060KB/s, mint=60001msec, maxt=60001msec and with sync=1: WRITE: io=6360.0MB, aggrb=108542KB/s, minb=108542KB/s, maxb=108542KB/s, mint=60001msec, maxt=60001msec My understanding is that since I'm operating on the raw block device, O_SYNC should not make any difference - there's no filesystem, any barrier, anything between the writes and the drive itself. Especially with O_DIRECT|O_SYNC set. Any ideas? For reference, here's the fio script I'm testing with: [global] bs=1M ioengine=sync iodepth=4 size=16g direct=1 runtime=60 filename=/dev/sdh sync=1 [rand-write] rw=randwrite stonewall

• Win 2008 r2 -- client and server are both behind a NAT

  - by Mike Dehari

  I am new to win2008. Have Win2008 R2 installed. Need to know how a client system (Win7), using remote desktop, terminal server, or whatever windows 2008 provides to connect to it (as a user or an admin). Both the client (Win7) and the server (win2008) are inside a NAT (with 192.168......... addresses). Both have real internet addresses (they are in different cities 173.64.......). How can I use the internet from the client (Win7) to connect to the server (Win2008). On both systems, I have "allowed other systems to connect". I am familiar with tcp/ip, ports......etc.

• What does the -P option do to mount?

  - by Simon

  I'm migrating from an archaic version of Red Hat to Ubuntu 9. When going through my old nfs mount script, I found that it contained the -P option. So my script looks like: sudo mount -t nfs -o -P ... It looks like the -P is one of the -o options. My question is: what does the -P option do? I've searched every man page I can find, with no luck. Could it have to do with privileged ports?

• Possible to get IIS on Windows Server 2008 R2 to "port-forward" port 80 for certain domains to other

  - by Lasse V. Karlsen

  I have IIS set up on my server, but also Apache x2 (other products which comes with their own servers, cannot be integrated into IIS.) Is it possible for me to "port-forward" certain domains on port 80 (that IIS handles) to those other ports? For instance: www.vkarlsen.no - IIS svn.vkarlsen.no - port 81 on same machine teamcity.vkarlsen.no - port 82 on same machine Or do I just need to set up those domains and redirect to the correct port? I'd like the domain name and url to be transparent to the user, but perhaps that won't work. Can anyone shed some light on this?

• Trouble opening my router to my web server [closed]

  - by justin

  Here's the story. I have a webs server created and connected to my router. The website works great when I'm connected to the router, but when I'm off the network I can't access the website. I got the IP for my router by googling "what is my ip." I have opened ports 80 to 10080 to link to the server in the router. THe firewall is off. I can ping the router. One odd thing that I don't understand. When I am in network if I access XXX.XXX.XX.XX:80 I can access the web page no problem. If I access XXX.XXX.XX.XX:81 (or any other port) I get the error "Cannot access server." Any idea what the problem could be? Could it be my ISP?

• How much traffic a linux-based shaper would be able to chew

  - by facha

  Hi, everyone I have a linux based traffic shaper (iptables + tc htb policy). It works in bridge mode. Shapes traffic based on IPs and ports (there are about 100 rules in the "mangle" chain of iptables). Right now its throughoutput is about 100 mb/s (I don't remember pps, there are about 800 users in the network). Just was wondering - when I will hit the limit. How much traffic could a linux-based shaper possibly get throuhg it. If you have one under heavy load, please could you write what machine you use and what load there is. Or if you have any other info about the subj, please write as well. Thanks in advance.

• Virtualmin Configuration

  - by Allen

  I am trying to get Virtualmin setup and have reached a point where my noobish sysadmin skills aren't getting the job done. This is the message I get now when I try and refresh the configuration of Virtualmin. BIND DNS server is installed, and the system is configured to use it. However, the default master DNS server XXXXXX is not a fully qualified domain name. Sendmail is only accepting SMTP connections on the following ports : 127.0.0.1 port smtp. Email from other systems on the Internet will not be accepted. This can be changed in the Sendmail Mail Server module. Please advise what I need to do to get Sendmail configured properly. Thanks!

• Performance difference between compiled and binary linux distributions/packages

  - by jozko

  I was searching a lot on the internet and couldn't find an exact answer. There are distros like Gentoo (or FreeBSD) which does not come with binaries but only with source code for packages (ports). The majority of distros uses binary backages (debian, etc.). First question: How much speed increase can I expect from compiled package? How much speed increase can I get from real world packages like apache or mysql? i.e. queries per second? Second question: Does binary package means it does not use any CPU instructions that was introduced after first AMD 64bit CPU? With the 32bit packages does it mean that the package will run on 386 and basically does not use most of the modern CPU instructions? Additional info: - I am not talking about desktop, but server environment. - I dont care about compile time - I have more servers, so speed increase more than 15% is worth for using source code packages - Please no flamewars. Thank you very much

• Cisco FC SAN switch decision

  - by Chopper3

  I've got to buy a bunch of FC SAN switches in the next week or so, I have to, and want to, buy Cisco MDSs. Servers are HP BL490c G6's in C7000 chassis with Virtual-Connect Flex-10 ethernet interconnects and VC FC interconnects (Emulex HBAs btw), all running ESX 3.5U4 (for now). I think I've only really got two choices; MDS 9509's with dual-supervisors with a single 48-port 4Gb FC card MDS 9222i's with single supervisor and the built-in 18-FC-port/4-GigE-FCIP-port option Both have the same functionality (I think, buying the enterprise licence btw), both have plenty enough performance and adequate ports for now and the next three years. The 9222i's are about 55% the price of the 9509's - logic says get the 'i's but will I really miss the dual-supervisors? I've got lots of 9509's with dual-supervisors that I'm very happy with but I'm not sure I've every benefitted from the dual-sups in the past and they are nearly twice the price - but if I don't buy them and miss them I can't retrofit them later. What are your thoughts?
