• What DBus signal is sent on system suspend?

  - by Paul Robinson

  Hello, I need to detect when a machine is going to sleep in Ubuntu 9.10 and Fedora 13. Both use UPower, so I've been looking on the "org.freedesktop.UPower" DBus bus for such signals. I've been listening for the "sleeping" signal on the UPower bus with the following command: dbus-monitor --system "type='signal',interface='org.freedesktop.UPower',member='Sleeping'" When I sleep the machine (either by closing the lid, selecting "shutdown - suspend" or sending a DBus message) I don't see a "sleeping" event. I notice that the "Sleeping" event is sent when the "org.freedesktop.UPower.AboutToSleep" method is invoked. I can do this manually by calling: dbus-send --print-reply --system --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.AboutToSleep And I notice the "sleeping" signal is fired. My understanding is that anything that sleeps the PC must send the "AboutToSleep" signal before hand. It doesn't seem like this is happening. I've tried these steps on both Fedora 13 and Ubuntu 9.10 and I see the same results. Can anyone explain what's happening or provide me with an alternative DBus signal to listen for? Many thanks, Paul

• Apache2/Shibboleth TCP connections stuck in CLOSE_WAIT

  - by RJT

  I run an Apache2 server which uses the Shibboleth daemon (shibd) as federated authentication module. Certain server connections using Shibboleth seem to stick permanently in CLOSE_WAIT state. tcp 38 0 blah.blah:57346 shib.server.:8443 CLOSE_WAIT tcp 38 0 blah.blah:45601 shib.server2:8443 CLOSE_WAIT tcp 38 0 blah.blah:41737 shib.server3:5057 CLOSE_WAIT From what I can find out, CLOSE_WAIT means that when the remote server disconnects, the local application is failing to close the connection, as it should. I suspect shibd is responsible somehow. Needless to say, if enough CLOSE_WAIT connections accumulate, I have a problem. Trying to get rid of the CLOSE_WAIT connections by simply using /etc/init.d/networking restart does not work. In fact networking seems to refuse to close down and restart, and I get a SIOCADDRT: File exists error (ie networking is trying to start without having stopped first). Same problem with ifup -a So I have two questions - one may be easy, and one harder. What's a good way to force networking to restart, and force whatever connections are stuck in CLOSE_WAIT to clear? Any ideas about how to fix shibboleth and force shibd module to behave?

• Fiber Channel Loop vs Point to Point

  - by RandomInsano

  So, I'm playing with a couple of QLogic QLA2340s connected directly together. I've got options here to either have them act as a loop, or in point to point mode. What's the difference if I'm only going to have two machines connected together? Is point-to-point more efficient? The firmware has an option to prefer loop, then fall back to p2p. Anyone have any idea if there are performance benefits or drawbacks? It's pretty hard to find that information.

• Network cabling with multiple patch panels?

  - by dannymcc

  I am in the very early stages of planning a network cabling upgrade in our office, mainly to upgrade the old cables from Cat5 to either 5e or 6. I am also planning on upgrading all of our 10/100 switches to 10/100/1000 switches. I would like to have three small wall mounted cabinets spread around the building, each with a patch panel and switch. These would all lead back to our server room. The question is; should I have two patch panels in each wall cabinet, one with 24 or 48 ports that are connected to a matching patch panel in the server room. The second patch panel would then link to each device in that cabinets area. Then I wouldn't put a switch in the small cabinets. All switching would be done in the server room. Or, should I have one main cable from the server room to each of the cabinets - plugged straight into the switch and the patch panel is for devices in the cabinets area? I hope that makes sense!

• MS Office Communicator: Long delays in setting up audio connection when starting a call

  - by geofftnz

  I am using Microsoft Office Communicator with a USB headset as my work phone. OCS is connected to our PABX so we can take and make calls to regular, non-OCS phones. When making an external call to a cellphone, it can take up to 5-10 seconds for audio to start flowing. eg: Work Phone Cellphone - dial cellphone (ringing) (ringing) answer cellphone (hearing nothing) speak "1" . speak "2" . speak "3" . ... . speak "14" hear "15" speak "15" hear "16" speak "16" Has anyone experienced this kind of thing with an OCS setup? Any pointers?

• Folder Redirection Issues - Freezing, Strange Warnings

  - by JCardenas

  I have Folder Redirection set up in a test environment for a couple accounts. I have followed the instructions for setting up the folder security settings here, and I can confirm that folders are created automatically by the system with the correct security settings when a user logs in. The GPO has been configured to automatically move user files up to the redirected folders, and this is working properly. Problems start occurring when a Windows 7 PC is in use. It is rare, but Explorer will lock up when performing a file write operation (move/copy/save from application). This results in the entire system being unusable, with only a hard reset resolving it (Task Manager doesn't start, the "three finger salute" does nothing, apps stop working). The mouse functions, but clicks do nothing. The other issue is that occasionally when copying/creating/modifying files a dialog box will pop up with the message "You need permission to perform this action. You require permission from XYZ\cardenas to make changes to this folder." The folder that was created by copying an existing one has the correct security settings and lists me as the owner. My company will not be implementing Folder Redirection on XP, since we are making a "clean break" with implementing new technologies with the Windows 7 rollout, so this behavior has not been - nor will be - checked for in XP. Thanks in advance for your help!

• Nginx + php5-fpm = "File not found"

  - by MatW

  I've hit a wall whilst setting up a site using nginx / fpm. The page displays "File not found", and this appears in the nginx error.log: FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream I'm new to both nginx and fpm, and that error message means nothing to me (even the google machine hasn't helped!). Can anyone shed any light onto what could be happening?

• How can I provide secure web content to mobile devices that can't access an intranet?

  - by evanmcd

  I'm working with a client on development web content for their intranet. We want users to be able to access a version of the content on their mobile devices, but most of them don't have the VPN capability to get on to their intranet. I'm wondering if anyone has had experience with this and can recommend a solution. One other thing to consider is that the content is not mission critically secure. If someone outside the company gained access to it, it would not represent a major issue, only a minor annoyance. Thanks for any advice.

• Application losing Printer within Terminal Services for remote users

  - by Richard

  Question: What I need to do is have a permanent link to a printer, normally only accessible through Terminal Services (Printer Redirect), to allow Sage Line 50 layouts to see that printer persistently, even after users have disconnected and reconnected to the Terminal Services session? Although the printer is accessible each time a user connects to the Sage Server via Terminal Services, it is given a different session number and therefore the Sage Layout sees it as a different printer. History behind question: Users using Terminal Services connecting to a Sage Server on a different site Using Sage Line 50 v 15 on that Server Users want to print invoices (sage layouts) locally Sage Server cannot see the users local printers, to get around this user uses the Print redirect features of Terminal Services The individual reports can be edited to point to a specific printer by default. This means the user just has to select an invoice and click print, then select the layout/report wanted and it auto prints that invoice to the default printer specified. The problem occurs because the layouts are edited to point to the users local printer "Ricoh 1018d (session#)", note the "(session#)" as this is the users local printer being redirected through the terminal services session. Users are able to print using the sage layouts once the default printer is setup within the layout and saved, but as soon as the users disconnects from the Terminal Services session and then reconnect in the morning go to print, it has lost the connection to that printer. I understand why its failed, because that the printer is on a per session basis and the layout would not be able to hold on to the connection from a previous session. Thanks in advance for any assistance...

• SIP and NAT routers?

  - by OverTheRainbow

  Hello SIP was not built with NAT routers in mind, and I'd like to get to the bottom of this issue to check what needs to be done on all devices so it works with NAT routers, and understand in what context it just can't be used and I should check more NAT-friendly alternatives like IAX. A picture being worth a thousand words, here's the layout I need to use: http://img62.imageshack.us/img62/4077/sipandnatrouters.jpg The PBX server is located in the private LAN behind a NAT router connected to the Internet (I know it'd be easier if it were located in the public network, but this router doesn't support DMZ's so the server has to be in the private network) A couple of (soft|hard)phones are located on the same LAN and connected to the PBX server, along with a PSTN gateway (Linksys 3102 or a Digium PCI card) Remote users using (soft|hard)phones are located somewhere on the Net with dynamic IP's and are also located behind NAT routers I may or may not have control over the local NAT router where the PBX server is located, but I have no control over the remote NAT routers, either because the users don't have the computer knowledge to map ports or because the routers are off-limit (eg. web cafés, hotel LAN's, etc.) Is it possible to configure the PBX server, the (soft|hard)phones, and the PSTN gateway so that the all conversations work fine, no matter the endpoints (POTS caller/local phone, POTS caller/remote phone, local phones, remote phone/local phone)? In which cases may I expect problems, and are there solutions? FWIW, I'm leaning toward using Freeswitch, but I could end up using Asterisk if there are technical advantages to it in this context. Thank you for any info.

• Bugzilla - How to setup MTA that will receive Gmail to create bugs

  - by JRock

  I have been looking for a while on setting up an MTA for bugzilla to receive bugs via email and am not really seeing any detailed guides. Currently I am using gmail as the outbound smtp for messages, but I do not have a solution for the receiving of emails as bugs. I am assuming I would setup an MTA and it would grab down the emails and then bugzilla would read them somehow. I am unsure of this process/a solution for this; Any detailed help or direction would be great. Distro: Ubuntu 11.10

• Is there a way to tell SGE to run specific jobs as root on the execution node?

  - by Rick Reynolds

  The title kinda says it all... We're using SGE/OGE to submit jobs to a set of worker nodes that then do things with specific pieces of equipment. The programs and scripts that have been created that manipulate this equipment rely on running as root. I'd like SGE to handle allocation of resources in a way that is mindful of users, groups, projects, etc., but I also need the actual jobs to run with root permissions. I've read up on How can one run a prologue script as root in gridengine? to see if anything there was pertinent, but it seems that SGE is providing the "user@" kind of spec specifically for prolog and epilog kinds of actions. Is there any similar functionality for the job itself? I'm aware of su/sudo approaches, but that won't really work in this environment because the sudoers file isn't globally managed (i.e. I'd have to add a whole set of users to /etc/sudoers on lots of machines). I'm currently looking into a setuid kind of solution, but that would definitely be an unnecessary kind of work-around if SGE provides me a way to declare that a specific job (or jobs in a specific queue) always needs to run with a specific user's rights.

• Cant get XAMPP Server to run?

  - by CitadelCSCadet

  I recently installed XAMPP server with PHP, MySQL, and Apache, and I had a friend help me load and configure it and it worked fine. I was able to play around with it, and load anything I wanted and I was able to confirm that it was working. When I went back to use it today, and I tried to run it Apache wont start up now. I imagine I either need to stop another service or there is something not allowing me to start up XAMPP, because even when I try to run the XAMPP_START script from the command line, it wont start.

• Welcome files are not loaded! Need help with Railo, mappings and J2EE configuration!

  - by mrt181

  I have installed a J2EE Server (tried it with Glassfish3, Tomcat6 and Resin4) on Win7 64bit and deployed Railo3.1. I have then added a virtual host to the J2EE server, i.e. Resin: <host host-name="railo"> C:/resin/webapps/railo In the Railo Admin i have added this mapping: Virtual Physical / C:/webapps/ When i access http://railo:8080/ my index.cfm welcome file in C:/webapps/ is loaded (index.cfm is definded in Railos web.xml). When i try to access http://railo:8080/test which contains the same index.cfm i get an 500 Servlet Exception java.io.FileNotFoundException: C:\webapps\test (access denied) (on all J2EE Servers i tried so far). http://railo:8080/test/index.cfm works fine. I already tried to add index.cfm to Resins welcome-file-list in app-default.xml to no avail. I want to be able to access deployed apps without this url: http://localhost:8080/app/ Instead i want to use this: http://app:8080/

• How to restrict file system when logged into terminal services

  - by pghcpa

  What I need to accomplish: With one login, when user is physically in the building I need them to see everything. When they are using terminal services with same login they should not be able to see the file system on the network. I can lock down the PC running terminal services as that is its only use. Details: Windows/2003 Server with terminal services. One login for a user (e.g., johndoe). When johndoe logs into the network at his desk in the office, he can see the network files according to group policy. When johndoe logs into terminal services from outside the building, we do not want to allow him see the network. Using 2x to do a published app, but that app has a "feature" that allows user to see network. Published application on termina services (only) is a document management system that is tied to windows login, so I can't give them two logins. With one login, when they are in the building I need them to see everything. When they are using terminal services they should not be able to see the network. I can lock down the PC running terminal services as that is its only use.

• IMAP/POP won't send allow emails to outside- New Dell PowerEdge 7310 running SBS 2011

  - by user779887

  I have a brand new out of the box Dell PowerEdge T310 running SBS 2011. Our employees at our remote offices can't send emails to recipients outside of our own domain. The workstations at the same location as the server aren't having any problem. I would at this time like to say "Thanks a lot" to the super-minds at Microsoft for protecting our email server from rogue computers attempting to send fake emails. (Silly me I thought proper login and password conventions would handle that.) I know this is something dealing with relaying but thus far nothing from any posts I've read have changed anything. Honestly, if someone is crafty enough to guess one of our login/password combos, let them send emails through our server I don't care!

• iptables (NAT/PAT) setup for SSH & Samba

  - by IanVaughan

  I need to access a Linux box via SSH & Samba that is hidden/connected behind another one. Setup :- A switch B C |----| |---| |----| |----| |eth0|----| |----|eth0| | | |----| |---| |eth1|----|eth1| |----| |----| Eg, SSH/Samba from A to C How does one go about this? I was thinking that it cannot be done via IP alone? Or can it? Could B say "hi on eth0, if your looking for 192.168.0.2, its here on eth1"? Is this NAT? This is a large private network, so what about if another PC has that IP?! More likely it would be PAT? A would say "hi 192.168.109.15:1234" B would say "hi on eth0, traffic for port 1234 goes on here eth1" How could that be done? And would the SSH/Samba demons see the correct packet header info and work?? IP info :- A - eth0 - 192.168.109.2 B - eth0 - B1 = 192.168.109.15 B2 = 172.24.40.130 - eth1 - 192.168.0.1 C - eth1 - 192.168.0.2 A, B & C are RHEL (RedHat) But Windows computers can be connected to the switch. I configured the 192.168.0.* IPs, they are changeable. Update after response from Eddie Few problems (and Machines' B IP is different!) From A :- ssh 172.24.40.130 works ok, (can get to B2) but ssh 172.24.40.130 -p 2022 -vv times out with :- OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 172.24.40.130 [172.24.40.130] port 2022. ...wait ages... debug1: connect to address 172.24.40.130 port 2022: Connection timed out ssh: connect to host 172.24.40.130 port 2022: Connection timed out From B2 :- $ service iptables status Table: filter Chain INPUT (policy ACCEPT) num target prot opt source destination Chain FORWARD (policy ACCEPT) num target prot opt source destination 1 ACCEPT tcp -- 0.0.0.0/0 192.168.0.2 tcp dpt:22 Chain OUTPUT (policy ACCEPT) num target prot opt source destination Table: nat Chain PREROUTING (policy ACCEPT) num target prot opt source destination 1 DNAT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:2022 to:192.168.0.2:22 Chain POSTROUTING (policy ACCEPT) num target prot opt source destination Chain OUTPUT (policy ACCEPT) num target prot opt source destination And ssh from B2 to C works fine :- $ ssh 192.168.0.2 Route info :- $ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 * 255.255.255.0 U 0 0 0 eth1 172.24.40.0 * 255.255.255.0 U 0 0 0 eth0 169.254.0.0 * 255.255.0.0 U 0 0 0 eth1 default 172.24.40.1 0.0.0.0 UG 0 0 0 eth0 $ ip route 192.168.0.0/24 dev eth1 proto kernel scope link src 192.168.0.1 172.24.40.0/24 dev eth0 proto kernel scope link src 172.24.40.130 169.254.0.0/16 dev eth1 scope link default via 172.24.40.1 dev eth0 So I just dont know why the port forward doesnt work from A to B2?
