• Destination host unreachable - Windows Server 2008

  - by Doug

  Hi There, I'm working with a windows 2008 domain controller, which I'm having issues connecting to internet resources. A small bit of background, this is a 2008 domain controller that has been added into an existing Win 2k domain, with a goal of replacing the older computers. Both of the older controllers can still access internet resources, and so can all the clients. When I ping Google.ca from the new server, it does resolve to an ip address, but then says "Reply from 192.168.123.20: Destination host unreachable." I'm really at a lost now, I've checked and rechecked my ip configuration, the default gateway is my router, the primary DNS server is the my DC, and the secondary DNS is also my router. The DNS server on the domain has a forwarder added for the router as well. Everything on my local network works just fine, all my internal resources can be resolved. For the time being, I've stopped the Firewall service. I'm not 100% used to Server 2008 yet, but it might be a case of just missing something simple. Thanks for your time.

• Automount in Ubuntu 9.10

  - by easyrider

  Hi, By default Ubuntu doesn't mount internal NTFS hard drives automatically. A fstab solution not working properly, because of conflicts with the "intelligent" mount system. If I add my hd in fstab and reboot - it will be mounted. But if I go to nautilus, open places panel and click eject button (unmount) and than click on hd again to mount it, I will get an error. In 9.04 to solve this problem you need to modify hal rules in /etc/hal/... preferences.fdi in my case I modified it for only one drive. <device> - <match key="storage.hotpluggable" bool="false"> - <match key="storage.removable" bool="false"> <merge key="storage.automount_enabled_hint" type="bool">false</merge> - <match key="storage.model" string="ST3250310NS"> <merge key="storage.automount_enabled_hint" type="bool">true</merge> </match> </match> </match> </device> But this is not working in 9.10 - devs removed this function from hal to devkit-disk or udev? I don't know. Could you please tell me where automount rules are stored in 9.10? And how to create new rules, and what program controls automount in 9.10?

• Nginx dynamic upstream configuration / routing

  - by Dan Sosedoff

  I was experimenting with dynamic upstream configuration for nginx and cant find any good solution to implement upstream configuration from third-party source like redis or mysql. The idea behind it is to have a single file configuration in primary server and proxy requests to various app servers based on environment conditions. Think of dynamic deployments where you have X servers that are running Y workers on different ports. For instance, i create a new app and deploy. App manager selects a server and then rolls out a worker (Ruby/PHP/Python) and then reports the ip:port to the central database with status "up". At this time when i go to the given url nginx should proxy all requests to the specified ip:port upstream. The whole thing is pretty similar to what heroku does, except this proof-of-concept is not supposed to be production ready, mostly for internal needs. The easiest solution i found was using resolver with ruby-based DNS server. It works, nginx gets the IP address correctly, but the only problem is that you cant define port number for that IP. Second solution (which i havent tried yet) is to roll something else as a proxy server, maybe written in Erlang. In this case we need to use something to serve static content. Any ideas how to implement this in more flexible and stable way? P.S. Some research options: http://openresty.org/#DynamicRoutingBasedOnRedis https://github.com/nodejitsu/node-http-proxy

• DrayTek 2820 configuration using public IP addresses

  - by Kev

  I have a /29 range of public IP addresses assigned to me by my ISP. I'm trying to configure a SIP VOIP handset to register with my VOIP provider who recommend using public IP addresses rather than NAT. I have a DrayTek 2820 router flashed with the latest firmware and have configured my router as per DrayTek's FAQ at: How do I use a public subnet on the LAN (non-NAT operation ) ? My IP range is: xx.xx.94.16 -> xx.xx.94.23 This gives a usable range of: xx.xx.94.17 -> xx.xx.94.22 My router's public IP address is: xx.xx.94.17, the SIP VOIP handset is allocated xx.xx.94.18. I have a second internet connection and via that I can ping the handset. However for some reason I can't seem to get it to register with the provider. I tried adding a new Firewall filter to pass through from WAN to LAN: Source: ANY, Destination: xx.xx.94.18, UDP - Ports 1024 -> 65535 Out of interest I also tried opening port 80 to see if I could browse to the phone's admin web interface but no joy. I know that my ISP aren't blocking inbound service ports because I NAT Port Forwarded port 80 to one of my internal web servers and it rendered a test page I had set up. All the NAT settings are reset to factory defaults, i.e. there are no Port Redirection, DMZ Host, Open Ports or Address Mappings configured. The handset I'm using is a GrandStream GXP-2000. Is there anything else I should be doing?

• nmap on my webserver shows TCP ports 554 and 7070 open

  - by atc

  I have a webserver that hosts various websites for me. The two services that are accessible outside are SSH and Apache2. These are running on a non-standard and standard port, respectively. All other ports are closed explicitly via arno-iptables-firewall. The host is running Debian Testing. I noticed that a scan of the host using nmap produced different results from different PCs. From my laptop on my home network (behind a BT Homehub), I get the following: Not shown: 996 filtered ports PORT STATE SERVICE 80/tcp open http 554/tcp open rtsp 7070/tcp open realserver 9000/tcp open cslistener whereas scanning from a US-based server with nmap 5.00 and a Linux box in Norway running nmap 5.21 I get the following: Not shown: 998 filtered ports PORT STATE SERVICE 80/tcp open http 9000/tcp open cslistener so I hope it's my internal network or ISP that's playing up, but I cannot be sure. Running a netstat -l | grep 7070 produces nothing. Similarly for port 554. Can anyone explain the peculiarities I'm seeing?

• How can I make my PCI-E graphics card visible to Ubuntu when the motherboard has integrated graphics

  - by Norman Ramsey

  I have a Gigabyte GA-MA74GM-S2 motherboard with integrated graphics that shows up on lspci as an ATI Radeon 2100. I also bought a PCI-Express Nvidia graphics card so I could use the VDPAU feature on Linux (plays H.264 in hardware). The BIOS has three settings about which display to initialize first: Integrated graphics PCI graphics PCI-Express graphics (PEG) I set the BIOS on PEG, but I cannot get anything, not even a splash screen or POST messages, to emerge from the PCI-Express graphics card. (I'm using a DVI connector; the card also has an HDMI output.) I cannot get the kernel lspci to see the graphics card; the only VGA controller it acknowledges is the integrated one. Running dmidecode acknowledges the existence of an x16 PCI Express slot, and it says Current usage: Unknown There is an additional BIOS setting called "Internal Graphics Mode" which is normally set to "Auto" which means it is supposed to prefer a PCI Express VGA card. I set it to "Disabled" which now means I'm getting no output at all. I will soon be learning how to do a BIOS reset! Other information: The PCI-E card is a MSI N210-MD512H GeForce 210. This is a fanless card. Although there are no fans to see turning, the heat sink on the PCI-E card is definitely getting hot, so the card is getting some sort of power. It gets all its power from the PCI-E slot; there is no external power connector. The BIOS is an AMI Award BIOS. My question: how can I make the PCI Express graphics card visible to Ubuntu?

• Address (url) forwarding with Vyatta

  - by Trikks

  Hi Got this kind of noob question i suppose. I got this very basic network setup and need help to set up some address forwarding. As seen in my illustration below all traffic enters via the eth0 interface (85.123.32.23). The external dns is setup to direct all hosts to this ip as well. Now, how on earth do I filter the incoming requests to each box? The Ip's are static! Se the network layout here: http://vyatta.org/files/u11160/setup.png I do not wish to solve this by assigning tons of ports etc. In my wishful thinking something like this would be nice :) set service nat rule 10 type destination set service nat rule 10 inbound-interface eth0 set service nat rule 10 destination address ftp.myhost.com set service nat rule 10 inside-address address 192.168.100.20 This way ALL traffic to the address ftp.myhost.com (at eth0) should be routed to the internal ip, 192.168.100.20. Right, is there anyone who could point in some direction? Maybe it's wrong to use nat? Please help me! :)

Where else might I look? thanks

• Recommended motherboard with hardware raid for Linux

  - by luison

  Hi. We want to setup an internal office server for testing jobs (LAMP), email and samba. Only about 5-10 users. We are also considering starting to virtualize, initially by a base Ubuntu Server with Xen or VMWare Open Source server. Our current system runs with a Linux Raid which has worked great but it's always been complicated to recover the boot sector when one the drives fail and therefore I would prefer using now a hardware raid instead, but ideally with some kind of software monitoring. For this reason and considering we don't want to spend a fortune a I would appreciate any comments on the following options. Motherboard with RAID with linux support... which could you recommend. Motherboard + Hardware Raid card... Adaptec does not seem to have great Linux suppport. 3Ware seems to have a tc soft controller which we've used on a hosting company, but hard to find here in Spain. HP Proliant type basic server, which? Dell Small Servers... any good for Linux? Thanks in advance for any feedback.

• CoreStore Encryption Error on Mac Lion

• Can't access IIS 7 server URL from the same IIS 7 server.

  - by Kevin Raffay

  We have an intranet site ie, xxx.yyyy.com, that users access by entering "http"://xxx.yyy.com. Our problems started when we migrated to IIS 7 running on a new 2003 server. We got rid of our single-sign on code and implemented a security model where we capture a user's domain credentials which we then authenticate against a DB. In order to get the domain credentials passed to our ASP.NET app, we have the following settings: Anonymous Authentication:Disabled ASP.NET Impersonation: Enabled Basic/Digest/Forms Authentication: Disabled Windows Authentication: Enabled We allow "*" and deny "?" in the web.config. Browsing "http"://xxx.yyy.com from any client PC results in a domain login prompt, and if your enter a proper user/pwd, you can get in. However, browsing "http"://xxx.yyy.com while remoting into the server results in 3 domain login prompts and eventually a 401 error - unauthorized. We have traced this behavior to problems with our web site where we have pages doing "screen scraping" using the HttpRequest calling a url on the same server. When doing a HttpRequest from any other client, using a test harness that passes authorized credentials, all is good. So internal HttpRequest calls on the server fail, just like attempts to browse that server's url from within a remote session. Why would a to "http"://xxx.yyy.com on server xxx.yyy.com fail authentication?

• Windows Server 2008 DHCP with RRAS

  - by Guillermo Prandi

  I have a Windows Server 2008 R2 which is a member of a domain, but is placed in a remote location. The server is directly connected to Internet. Clients need to access a particular insecure TCP service in this server (ports 9730 and 9731). Since clients have dynamic IP addresses I cannot know in advance, I thought it would be nice to have them connected through a VPN in order to access the insecure service, but ONLY to access that service, like this: Client ------> VPN TUNNEL ------> (Insecure service at Server) | \----> (Normal internet access) I'd enable the insecure ports in the firewall only from VPN accesses. For this I configured RRAS in the server and gave it a static IP address range (172.19.1.2 through 172.19.1.254) to serve the clients. First I thought I could use DHCP to assign the addresses, but I cannot use DHCP in my LAN connection (not allowed by the hosting service). I tried configuring DHCP binding it to a Microsoft Loopback Adapter, but that's not supported as a DHCP source by RRAS. What I want to accomplish is to send specific DHCP options to the client (network mask, routing table, etc.). In particular: Prevent the client from having the server as default router (without changing the client's "use default gateway in remote network"). Have it as a route for the server's internal RRAS address only (172.19.1.1). Prevent the client from using a 255.255.0.0 mask for the 172.19.x.x network (a 255.255.255.0 mask would be better). Can I do that with RRAS only? How? Currently, the only solution I can think of is to use DHCP in the LAN adapter, but filter DHCP packets so they don't reach the provider's network. However, I'm not sure if that will work. Any suggestions are welcomed! Guille

• Bringing people into an Asterisk conference call

  - by Harley

  I'm using Asterisk 1.4 and am trying to work out a way to bring people into a conference call. In the ideal scenario two people would be talking and one of them would push some keys, then a phone number and then the three of them would be in a conference. From there they should be able to bring in other people as well. This seems to be what the Asterisk n-way call HOWTO is trying to do, but it doesn't work quite properly for me. Here's what happens: 1. Internal person A calls person B 2. Person A presses *0, he is given a dial tone and person B is taken to a conference room 3. Person A calls person C and they can talk, and then person A presses **. 4. Person C is brought to the conference room, but person A is disconnected. In the last step, A should be taken to the conference room as well. Here's the relevant logs, where 230 is person A, 231 is person B, 207 is person C, and 282 is the conference room.

• Migrating from "partial" Exchange 2003 to full Exchange 2003 usability

  - by TheCleaner

  I have a client that is using Exchange 2003 on SBS 2003 R2, but only for calendar sharing and contacts sharing. Their email is still coming to their clients via a POP3 account on each client's Outlook. I'd like to move them over to using Exchange for both email and the other things they are utilizing it for now. Can you folks guide me in the right direction? The setup: external domain is akin to domain.com (and is where they get their POP3 email from now) internal domain is akin to domain.local only simple hardware firewall (no ISA) static external IP is available to use My "assumptions": Setup SMTP default connector in Exchange for their existing external domain Have their existing email backed up to PST files (just in case) Setup the new MX records to point domain.com to the static external IP I'm a little confused how I'm going to setup their existing Exchange accounts with the proper SMTP address though. Right now it is just [email protected]. Do I just need to modify or create a new recipient policy? Are there other steps involved that I'm missing? Anyone with a walkthrough or even a basic "steps" is fine. I'm fairly used to Exchange 03, but I've been on Exchange 07 for a while now so going back is the weird part...plus I don't know what issues Exchange 03 on SBS has versus the normal "version". Thanks for all the help!

• RDS, RDWeb, and RemoteApp: How to use public certificate for launching apps on session host?

  - by Bret Fisher

  Question: How do i tell RDWeb to launch apps from remote.domain.com rather then host.internaldomain.local? Environment: Existing org with AD forest. New single Server 2012 running all Remote Desktop Services roles for session host. Used the new 2012 wizard to setup "QuickSessionCollection" with roles: RD Session Host RD Connection Broker RD Gateway RD Web Access RD Licensing Everything works with self-signed cert, but we want to prevent those. The users are potentially non-domain machines so sticking a private root cert for on their machines isn't an option. Every part of the solution needs to use public cert. Added public remote.domain.com cert to all roles using Server Manager GUI: RD Connection Broker - Enable Single Sign On RD Connection Broker - Publishing RD Web Access RD Gateway So now everything works beautifully except the last step: user logs into https://remote.domain.com user clicks a app icon, which in background downloads a .rdp file that is signed by remote.domain.com. .rdp is set to use RD Gateway, which is remote.domain.com .rdp says app is hosted on internal host.internaldomain.local, which doesn't match the RDP-tcp TLS cert of remote.domain.com, and pops a warning. It's this last step that I'd like to fix. Is there a config option in PowerShell, WMI, or .config to tell RDWeb/RemoteApp to use remote.domain.com for all published apps so the TLS cert for RDP matches what the Session Host is using? NOTE: This question talks about this issue, and this answer mentions how you might fix it in 2008, but that GUI doesn't exist in 2012 for RemoteApp, and I can't find a PowerShell setting for it. NOTE: Here's a screenshot of the setting in 2008R2 that I need to change. It tells RemoteApp what to use for the Session Host server name. How can I set that in 2012?

About 80% of the time, the puppet agent --test completes successfully: info: Retrieving plugin info: Caching catalog for test3 info: Applying configuration version '1333319732' notice: Finished catalog run in 5.08 seconds The other 20% of the time, it fails midway, with errors such as the following: err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find class iptables for test1 at /etc/puppet/manifests/site.pp:1 on node test1 warning: Not using cache on failed catalog err: Could not retrieve catalog; skipping run or info: Retrieving plugin info: Caching catalog for test2 info: Applying configuration version '1333319732' notice: Finished catalog run in 24.73 seconds err: Could not send report: Error 500 on SERVER: Internal Server Error private method `gsub' called for WEBrick::HTTPStatus::RequestTimeout:Class WEBrick/1.3.1 (Ruby/1.8.5/2006-08-25) OpenSSL/0.9.8e-rhel5 at puppet:8140 or info: Retrieving plugin err: Could not retrieve catalog from remote server: execution expired warning: Not using cache on failed catalog err: Could not retrieve catalog; skipping run or info: Retrieving plugin info: Caching catalog for test3 info: Applying configuration version '1333319732' notice: Finished catalog run in 9.47 seconds err: Could not send report: Error 408 on SERVER: Request Timeout During this time, I've not made any changes to the Puppet configuration — it just sporadically fails. I'm running puppet-2.7.12 on CentOS, and followed the setup instructions described on http://docs.puppetlabs.com/learning/agent_master_basic.html. Any ideas about how I can troubleshoot this?

• error 20014 with mod_proxy

  - by punkish

  I have strange situation. I need to call a program in cgi-bin from within a perl script. When I try to do that with exec($program), I get (20014)Internal error: proxy: error reading status line from remote server proxy: Error reading from remote server returned by ... The long story... I am calling mapserv (http://mapserver.org) as a cgi program from OpenLayers (http://openlayers.org). Ordinarily, my web site is served by Perl Dancer, but the mapserver calls are made directly to http://server/cgi-bin/mapserv from JavaScript. The Dancer web site is served by Starman behind an Apache2 proxy front-end. This is how it looks [browser] -> http://server/app -> [apache2] -> proxy port 5000 -> Starman | | +-> http://server/cgi-bin/mapserv -> [apache2] -> cgi-bin -> mapserv This is what I am trying to accomplish [browser] -> http://server/app -> [apache2] -> proxy port 5000 -> Starman | | mapserv <-- cgi-bin <-- [apache2] <--+ I saw this question re: 20014 error, but that suggested solution didn't help. Any other hints?

• How do I install OpenStack on a single Ubuntu 12.04 node?

  - by Sam Edwards

  I'm having trouble installing OpenStack in Ubuntu 12.04, for various reasons: The official Ubuntu website recommends Juju and MAAS. However, this is a single node I am trying to get OpenStack installed on, and MAAS requires "two or more nodes" according to the docs. Additionally, I don't have any experience in MAAS and Juju and would rather stick to technologies I am more familiar with so that I can debug problems that arise. I have tried StackGeek but this fails because the node only has a single Ethernet port. The node does, however, have the second hard drive required for the nova storage. I have tried DevStack but cannot log into the dashboard. The login form appears fine, but as soon as I try to submit the page, my browser begins loading indefinitely. I have tried installing straight from packages, but I get an Internal Server Error in the dashboard upon trying to log in, with no helpful logs anywhere in sight to aid me in debugging the issue. Each of these attempts was with a fresh Ubuntu 12.04 LTS setup; I'm finding it really strange that no matter what I try, I cannot get OpenStack installed. Is this even a stable/mature project? Why am I encountering so many bugs?

• wget mirroring, subdomains and directories and cookies

  - by Jimmu

  Hi all, I have an account on a web page that is now "full" (ie I have used up all my allocated space) and I would like to make a mirror of that site. wget seems like the thing to use. The problem is that I would only like to mirror the sites the lie within this directory http://user.domain.com/room/2324343/transcript/ (and sub-directories). Whilst saving the correct stylesheets, javascripts and css etc which exist in different directories. There as also uploaded files that are linked to within the pages in the transcript directory (on different directories) that I would like to download/mirror (theses are in a variatey of formats .exe, .py, .png, .app (and many more)). There are also images that are on different severs that are on these pages. Also I would like it if the links (which are sometimes relative , sometimes absoulute (but to internal things), sometimes external ) worked correctly so that if they link to things that have been downloaded(mirrored) they work fine (without internet connection), but if they link to things that are external or havent been mirrored they link to the external site. Basically so they work as expected. Another problem is that you have to log in to acess the site. Can wget be used to acomplish this or is there a better way? either way how do I achive this? (I have asked this question at stackoverflow.com/questions/2190115/wget-mirroring-subdomains-and-directories-and-cookies but it was recommended that I try asking it here)

• Microsoft Remote Desktop Services - Android

  - by Matt Rogers

  We have recently started testing Remote Desktop Services. We have deployed the environment using the latest server, Windows Server 2012 R2. We have deployed the Web Access Roles, RD Gateway, Connection Broker Virtualization Host and Session Host. We are running both, Virtual machine-based and Session-based deployments. All of these are working as expected internally and externally when using a Windows workstation as the RDS client, however, the Android client is unable to launch applications. Once you install the app from Google Play you are given a screen to add Remote Resources. After entering the appropriate URL, username and password we see the applications that have been published. Unfortunately, when we attempt to launch an app we get the following error: Connection Error Host not found. Please provide the fully-qualified name or the IP address of the host. We have already entered this information otherwise I don't believe we would be able to see the published applications. I think the error is related to the certificate and how it is being used to connect to the applications. Since this is in our lab environment we have not configured a valid external certificate on the servers and the trusted certificate that is installed on the android tablet points to our internal server / domain name. What I would like to know: Has anyone configured RDS Web Access on Server 2012 R2 and attempted to externally connect an Android or iOS device using the Microsoft supported Remote Desktop client. Are others experiencing the same problem we are? Were you able to resolve the issue? Was it related to the external cert / host name?

• Word documents very slow to open over network, but fine when opened locally - on one machine

  - by Craig H

  Windows XP, Word 2003, patched. The issue is happening with several Word documents stored on a network drive. The Word documents are clearly a bit wonky (i.e. one is 675k, but if you copy everything but the last paragraph marker into a new document, the new document is only 30k). But that's only part of the problem. On one weird machine, and one machine only, it takes ~20 seconds to open these Word documents from the network drive. Copy the file to C: on that werid machine? Opens immediately. Go to other machines (that are very similar - same patch level, etc.) and open the same document from the network? Opens immediately. Delete normal.dot? 20 seconds. Login with a different user on the weird machine? 20 seconds. Plug wonky machine into a different network port? 20 seconds. So the problem appears to be hardware related (i.e. wonky internal NIC) or related to a setting that is not profile specific. Any ideas? "Scrubbing" all the documents isn't ideal for several reasons. This is driving me nuts because I swear I ran into this before many years ago and eventually figured it out. But I appear to have lost my notes.
