• How can I tell which page is creating a high-CPU-load httpd process?

  - by Greg

  I have a LAMP server (CentOS-based MediaTemple (DV) Extreme with 2GB RAM) running a customized Wordpress+bbPress combination . At about 30k pageviews per day the server is starting to groan. It stumbled earlier today for about 5 minutes when there was an influx of traffic. Even under normal conditions I can see that the virtual server is sometimes at 90%+ CPU load. Using Top I can often see 5-7 httpd processes that are each using 15-30% (and sometimes even 50%) CPU. Before we do a big optimization pass (our use of MySQL is probably the culprit) I would love to find the pages that are the main offenders and deal with them first. Is there a way that I can find out which specific requests were responsible for the most CPU-hungry httpd processes? I have found a lot of info on optimization in general, but nothing on this specific question. Secondly, I know there are a million variables, but if you have any insight on whether we should be at the boundaries of performance with a single dedicated virtual server with a site of this size, then I would love to hear your opinion. Should we be thinking about moving to a more powerful server, or should we be focused on optimization on the current server?

• Windows RDP cannot connect to x64 server from XP SP3+

  - by Tom

  Hi all, I have a strange problem that I can't seem to find the answer to anywhere online. The issue has to do with using Windows RDP to connect to our servers. Here is what works: -XP/Vista client (any SPs) connecting to 32-bit Server 2003 machine -XP (SP2 and lower) client conecting to 64-bit Server 2003 machine Here is what does not work: - XP SP3+/Vista client connecting to 64-bit Server 2003 machine It appears that the issue is that XP SP3 and Vista clients cannot connect to x64 Server 2003 boxes. After entering the username/password, we get an error message saying the below, and the connection drops: To log on to this remote computer, you must have Terminal Server User Access persmissions on this computer. By default, members of the Remote Desktop Users group have these permissions. If you are not a member of the Remote Desktop Users group or another group that has these persmissions, or if the Remote Desktop User group does not have these permissions, you must be granted these permissions manually. The issue is that the user is a member of the Administrators group, which has permission. Also, logging in using the same username, but from an XP SP2 machine, has no problems at all. I hope I explained this well enough, and any help/insight that can be given would be greatly appreciated. Thanks, Tom

• Window 7 image in vmware will allow network connection out but not http

  - by Ormis

  I am currently trying to create a set of images to deploy on my network, but I've run in to a snag. When I create my own Windows 7 image I can successfully use NAT for connecting to the network but whenever I try to access a webpage I get nothing. To be more specific, All firewalls/iptables are disabled on my host machine, my virtual machine, and my network. I can do lookups and all addresses respond correctly (i'm even using Google's DNS). On the host OS i have full connectivity. On the virtual machine I can ping any device I want and all addresses resolve correctly. Within a browser I cannot reach any page via hostname or IP. I feel almost like port 80 is being blocked but i can't find any reason this would be the case. If anyone has had this occur before, I would love some insight to the problem. I understand this question is a bit out of the norm for stackoverflow, but I've run out of ideas. Thank you for any help you can provide.

• Is it possible to re-cab an Administrative Install Point?

  - by Nathaniel Bannister

  We have Acrobat 8 Pro at work, and our media was painfully out of date. Rather than install all of the machines at 8.0.0 and then do the 6 or 7 consecutive reboots adobe expects you to be ok with I decided I'd integrate the .msp files into the installer. After reading up on it, I figured out the exact patch order that adobe required, extracted my cd to an Administrative install point, and ran the patches against it: msiexec /a AcroPro.msi /p AcrobatUpd810_efgj_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd811_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd812_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd813_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd816_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd817_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd820_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd822_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd823_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd825_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd826_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" Now I have a AIP that is fully patched to 8.2.6 (Tested working prior to attempting to CAB it), but is absolutely huge (1.2gb) what I would like to do is take the folders within the AIP and put them back into a cab file for the sake of convenience in transferring the files around. I tried the command: cscript "C:\Program Files\Microsoft SDKs\Windows\v7.0\Samples\sysmgmt\msi\scripts\WiMakCab.vbs" AcroPro.msi Data1 /L /C /S Per the guide I was using, while this did produce the cab file I Wanted, however the resulting MSI fails to install with an error 2602: It's been a while since I've done something like this, and it's probably a glaring oversight on my part, but any insight would be much appreciated.

• Excel file growing huge (>150 MB)

  - by Josh

  There is one particular Excel file that is used by a number of employees at my company. It is edited from both Excel 2003 and 2007, with the "Sharing" feature turned on to allow multiple writers at once. The file has a decent amount of data on several sheets with some basic formatting, and used to be about 6MB, which seems reasonable for its content. But after a few weeks of editing, the file grew to 10, then 20 MB, and eventually skyrocketed to more than 150 MB, even though it still has about the same amount of data as before. It now takes 5-10 minutes to open it, and that much time again to save it. The first time this happened, I copied the content of each sheet into a new, blank workbook, and saved the new workbook; this brought it back down to about 6MB. Now, it has blown up again. The workbook uses the "Data Validation" feature to limit the values in certain columns to the contents of a few named ranges. Copying all the data into a new workbook means re-setting up all the data validation, which is a pain and not something that we want to do every month. As a troubleshooting step, I tried saving the file in "XML Spreadsheet 2003" format, hoping to get some insight into what was being stored. Sure enough, the file was almost a gig, and almost all of the 10 million lines look like this: <NamedCell ss:Name="Z_21D5114F_E50C_46AC_AA4F_C3FF540C717F_.wvu.FilterData"/> <NamedCell ss:Name="Z_1EE2BA5E_3011_4F9A_8ACD_E58835250FC4_.wvu.FilterData"/> <NamedCell ss:Name="Z_1E3BDCEA_6A72_4ECC_BF4F_7B03CC66181E_.wvu.FilterData"/> I've seen a few VBScripts online to manage and enumerate named cells that are hidden in Excel's built-in interface, though I wonder how they'd handle my 10 million named cells. What I really need, though, is an understanding of why this keeps happening. What actions in excel could be causing this?

• Apache 403 Forbidden Error when accessing local web server using local IP address

  - by amjo324

  I have an odd problem when attempting to browse to pages stored on a local web server (Apache 2.2). The pages are served as expected when I browse to localhost or 127.0.0.1 on port 80. Yet when I attempt to browse to the same pages by referencing the local IP address (192.168.x.x), I receive a HTTP 403 (Forbidden) error. In essence, http://localhost:80 works but 192.168.x.x:80 doesn't even though I'm specifying the IP of the local machine. You may be thinking "who cares? just use localhost". However, this is the first step in troubleshooting why I cannot remotely access these pages from different hosts on my LAN. I'm presuming this can't be a firewall issue as I'm only connecting to the local machine. Even so, I verified there was no iptables rules that could be having an effect. I've checked the Apache error logs and the corresponding line of relevance is: [Sat Oct 19 07:38:35 2013] [error] [client 192.168.x.x] client denied by server configuration: /var/www/ I've inspected most of the apache config files and they don't appear to differ from what you would expect with a default install. I can't see anything in apache2.conf that would be a problem and httpd.conf is an empty file. This is an excerpt from /etc/apache2/sites-enabled/000-default: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> Any insight as to where I can look next to find a solution ? Thanks in advance.

• script calling script as other user

  - by viktor tron

  Using CentOs, I want to run a script as user 'training' as a system service. I use daemontools to monitor the process, which needs a launcher script that is run as root: : #!/bin/bash exec >> /var/log/training_service.log 2>&1 setuidgid training training_command This last line is not good enough since for training_command, we need environment for training user to be set. : su - training -c 'training_command' gives 'standard in must be tty' as su making sure tty is present to potentially accept password. I know I could make this disappear by modifying /etc/sudoers a la Bash & 'su' script giving an error "standard in must be a tty" but i am reluctant and unsure of consequences. : runuser - training -c 'training_command' gives runuser: cannot set groups: Connection refused. I found no sense or resolution to this message. I am stuck. Is this something so hard to achieve? I appreciate all insight and guidance to best practice.

• How do I get netcat to accept connections from outside the LAN?

  - by Chris

  I'm using netcat as a backend to shovel data back and forth for a program I'm making. I tested my program on the local network, and once it worked I thought it would be a matter of simply forwarding a port from my router to have my program work over the internet. Alas! This seems not to be the case. If I start netcat listening on port 6666 with: nc -vv -l -p 6666, then go to 127.0.0.1:6666 in a browser, as expected I see a HTTP GET request come through netcat (and my browser sits waiting in vain). If I go to my.external.ip.address:6666, however, nothing comes through at all and the browser displays 'could not connect to my.external.ip.address:6666'. I know that the port is correctly forwarded, as www.canyouseeme.org says port 6666 is open (and when netcat is not listening, that its closed). If I run netcat with -g my.adslmodem's.local.address to set the gateway address, I get the same behavior. Am I using this command line option correctly? Any insight as to what I'm doing wrong?

• Sporadic crash of master-slave MySQL replication process

  - by obarshay

  Hello, I was wondering if someone has experienced this and can perhaps provide some insight into this issue. We have a plan-vanilla MySQL master-slave replication set up. The tables are MyISAM and the master can get quite read/write active. We use the slave instance to perform full daily backups in order to avoid bringing down the master server. The backup process does the following: STOP SLAVE SQL_THREAD mysqlhotcopy all tables START SLAVE SQL_THREAD Every once in a while (once a month or so) the replication breaks with varying error messages indicating a corrupt query or log file. Here's one that happened last night: mysql> show slave status \G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: server8.propreports.com Master_User: nexus8 Master_Port: 3306 Connect_Retry: 60 Master_Log_File: bin.000045 Read_Master_Log_Pos: 581644327 Relay_Log_File: relay.000086 Relay_Log_Pos: 94131 Relay_Master_Log_File: bin.000045 Slave_IO_Running: Yes Slave_SQL_Running: No Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 1064 Last_Error: Error 'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '138070603'£' at line 1' on query.

Any advice on how to resolve this would be greatly appreciated.

• Windows 7 UAC (user access control) is being disabled on every reboot

  - by Christian Thamer

  To put it simply, I noticed UAC was disabled so I enabled it. I was prompted to reboot the computer for the changes to take effect. Upon my reboot I checked the settings again as I hadn't disabled UAC in the first place. It was again set to off (never notify). For the heck of it I repeated the process a couple of more times. Same result each time. I have Microsoft Security Essentials running a full scan nightly so I should be protected from viruses. I also did an on demand scan with the online tool at www.antivirus.com. Nothing was found. Other than the fact that UAC is being disabled on each reboot I have no other reason to suspect a virus. So my question is does anyone have insight into if this is a possible problem with a virus or other malware changing my UAC settings on each boot or is it possibly a problem with Windows and UAC itself? If it is malware are there suggestions for other products outside of the ones I have used to detect and remove it.

• Apache logging issues

  - by Dan

  I'm trying to parse apache log files, but I'm finding some strange results and I'm not sure what they mean. Hopefully someone can provide some insight. (all of the IP addresses were altered. none actually start with 192, I didn't figure the search engines mattered though.) In the first example, multiple ip addresses are showing up in the host field: 192.249.71.25 - - [04/Aug/2009:04:21:44 -0500] "GET /publications/example.pdf HTTP/1.1" 200 2738 192.0.100.93, 192.20.31.86 - - [04/Aug/2009:04:21:22 -0500] "GET /docs/another.pdf HTTP/1.0" 206 371469 What causes this? Does it have to do with proxy servers? Is there a way to have Apache only log one? In the second example, a bunch of information is just completely missing!

• IIS6 intranet site using integrated authentication fails to load when accessed externally

  - by maik

  I've developed a couple of internal sites for my organization that use integrated authentication. Ultimately we want these sites to be accessible externally to users with domain-joined computers. The sites work as expected on domain computers while on the internal network. The problem comes when I take my laptop home and try to access those sites. IIS only has integrated authentication enabled for the two sites. When I browse to the site using IE8 I get a username/password prompt asking for domain credentials. I can put those in and it will work, but the goal is to use the cached token for integrated authentication. Next I reasoned that IE wouldn't response to an integrated auth request (is NTLM the right term for this?) unless the site was trusted. I tried adding the site to Trusted Sites but I get the same behavior as the before. I then added the site to Local Intranet sites and that is where things get weird. I get a generic error page from IE, no error code or anything. Just for funsies I loaded up Firefox (which I had previously set up to use integrated authentication) and I added this new site to network.automatic-ntlm-auth.trusted-uris. Much to my surprise I was able to load the pages up with no problem at all and saw exactly what I was expecting (including verification that the integrated authentication worked). My mind is a bit boggled at the moment as I'm not really sure where to go from here. I was hoping some of you may be able to provide some insight.

• Installing sqlite gem fails on AWS Linux instance with sqlite-devel libraries installed

• how to design pound -> varnish -> jboss for ha + loadbalancing

  - by andreash

  Hello, I'm planning a new infrastructure for our web application. We have two JBossAS5 servers, running in a cluster. Session state will be replicated via JBoss Cache. In front of that, there should be some cache, to speed up delivery of static elements. However, most of the traffic to our app will be via HTTPS. So far, I had been thinking of two Varnish caches in front of the JBossASs, each being configured for loadbalancing to the two JBossASs via round-robin. Since Varnish doesn't handle HTTPS, then there would need to be two pound proxies in front of the Varnishs, dealing with the HTTPS. The two pounds would be made high-available with Heartbeat/LinuxHA. The traffic to www.example.com would then be going through our firewall, from there to the virtual IP of the pounds, from there to the Varnishs, and from there to the JBossASs. Question 1: Does this make sense? Or is it overly complicated, and the same goal can be reached with simpler methods? Question 2: If my layout is fine, how do I configure the pound - Varnish step? Should I a) make the Varnish service high-available through Heartbeat/LinuxHA as well and direct traffic from pound to the virtual IP of the Varnishs, or should I rather b) Configure two independent Varnishs and use load-balancing in pound to address the different Varnishs? Thanks a lot for your insight! Andreas.

• How can I setup BluePill to Monitor a Rails App Running via Passenger (mod_rails)

  - by Jim Jeffers

  I recently launched a site running phusion passenger. Unfortunately, the site went down due to a frozen thread. I was able to save the server by doing kill -9 to the specific PID. Still though, I thought passenger was able to manage this automatically. I have a server with 1GB of memory running one rails app with passenger allotted up to 7 instances. However, when I came to discover the site went down I found that passenger had spawned 6 instances with one of them using up over 800mb of memory causing the server to swap. As a result I am hoping to setup something like bluepill on the server but I'm slightly confused as to how you go about doing it. Mainly because bluepill expects to start/stop the processes it's monitoring. However, in our case, passenger already restarts processes for us so we only need to monitor the pids of passengers instances and kill them once they've gotten too large. Has anyone here setup BluePill to monitor a rails app running under phusion's passenger? Any insight would be useful.

• Linux Mounting Problem

  - by Sam

  I have an Iomega Network Attached Storage device on my Windows network. I am trying to use a clonezilla live USB flash drive to backup my netbook to my Iomega Network Attached Storage device. The clonezilla USB flash drive runs linux. I'm having trouble getting the Network Attached Storage unit to mount using the following command: mount -t cifs -o username="myUsername" //192.168.1.100/backup /home/partimg The response from linux is: [134.730738] CIFS VFS: cifs_mount failed w/return code = -6 retrying with upper case share name [134.788461] CIFS VFS: cifs_mount failed w/return code = -6 mount error(6): No such device or address Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) I also tried adding the following to my username: username="myUsername,domain=workgroup" but that did not change the error. I am able to ping the network attached storage unit from linux on my netbook. I also booted from a Slax Live USB Flash Drive and Slax auto-mounted my network attached storage unit via Samba. Unfortunately, I don't believe that I can run clonezilla from inside the Slax installation. Does anyone have any insight about what is wrong with my mount statement? Or is there something peculiar about Iomega drives which makes this impossible?

• Where in the stack is Software Restriction Policies implemented?

  - by Knox

  I am a big fan of Software Restriction Policies for Microsoft Windows and was recently updating our settings for this. I became curious as to where Microsoft implemented this technology in the stack. I can imagine a very naive implementation being in Windows Explorer where when you double click on an exe or other blocked file type, that Explorer would check against the policy. I call this naive because obviously this wouldn't protect against someone typing something in a CMD window. Or worse, Adobe Reader running an external application. On the other hand, I can imagine that software restriction policies could be implemented deep in the stack almost at the metal. In this case, the low level loader would load into memory the questionable file, but mark the memory in the memory manager as non-executable data. I'm pretty sure that Microsoft did not do the most naive implementation, because if I block Java using a path block, Internet Explorer will crash if it attempts to load Java. Which is what I want. But I'm not sure how deep in the stack it's implemented and any insight would be appreciated.

• vmware - ACE, Workstation - how to manage remoe clients??

  - by tom smith

  Hi. Exploring Vmware products/services and have a few questions. As I understand VM, you can use VMWare Workstation to create a VM of a target machine/box/OS. Let's call this VM, "foo". If I have 100 client PCs in my dept, and I want to install the VM (foo) on each client, and also manage the remote VM instances of (foo). How can I accompish this? Let's assume that the client machines are running Windows7, and have the vmplayer app installed on the box. I'm looking to do the following kinds of actions regarding the remote client machines: -Update the foo VM/image with new updated copies -Make sure that every VM "foo" has the same user, but a unique passwd -Monitor the traffic/status of each client VM "foo" oin each client -Start/Stop each client VN "foo" from the master console -Etc... Can this be accomplished? How would I do it, what services/products would I need? I've tried toalking to a few of the pre-sales guys in VMWare, and got nowhere, other than telling me to email my questions!! Looking at google shed more insight, but I still have questions. So, if you have detailed VMWare understanding, pointers to consultants, or resellers who can help, all pointers are greatly appreciated. Thanks -tom

• Windows 7 Folder Redirection (GPO)

  - by Kev

  I have been fighting this issue for a day or two now, so I am looking for some insight. I am taking over admin duties in a domain of 800 users, and the previous admins really did not employ much of any GPO settings for the clients of the Domain. In each site, there is a location on the file server where "Home" folders were manually created. EX: \server\home\enduser Whenever a user got a machine, the admin would manually right-click on the "My Documents" folder and manually enter the path to the home folder. We are planning to start putting Windows 7 machines on the Network, and I am wanting to automate as much as I can, everything that was not done in the past. Since everyone has exising "Home" folders I have been fighting and trying to get Folder Redirection to work with a new Windows 7 machine (In a Test OU). I am getting all kinds of errors and I can't get the Windows 7 "Documents" folder to redirect to the users EXISTING home folders. As I stated earlier, all of the Home folders were (and still are) manually created on the File Server and are set with the following Security permissions - Domain Admins - Full Control euser (end user) - Modify (Everything but Full) Can someone point me in the right direction on the proper setting to put in the Folder Redirection GPO to get this to work with the Existing Home folders.

• Very uneven CPU utilization with SQL Server 2012 on 2 processor computer with 16 cores / processor

  - by cooplarsh

  After installing SQL Server Enterprise 2012 with the Server + Cal license model, on a computer with 2 processors each with 16 cores (and no hyperthreading involved) and putting the server under extremely heavy load the 16 cores on the first processor were very underutilized, the first 4 cores on the 2nd CPU were heavily utilized, and the last 12 cores were not used at all (because of the 20 core limit for this sql server version). Total CPU utilization was displaying as around 25%. Unfortunately, the server suffered from extremely poor performance even though if the tasks were evenly distributed across the 20 cores it wouldn't have been anywhere near as bad. The Windows Server was running on a VMWare virtual image under ESX Server, but all of the CPU was allocated to the windows server. We tried changing affinity settings (e.g., allocating most cores to CPU and the others to I/O), but that didn't help solve the performance problems. Upgrading the product edition to SQL Server Enterprise Core 2012 not only allowed the SQL Server to utilize the 12 previously unused cores on the 2nd processor, but it also resulted in a much more even distribution of tasks across all of the processors. To get through the backlog of requests cpU utilization jumped to around 90%, and then came down to around 33% once it was caught up, but performance improved dramatically since we failed over to the newly updated version And the performance issues went away. I was wondering if anyone knows what might cause SQL Server to unevenly distribute the load, relying almost exclusively on the first 4 cores of the 2nd processor that had 12 cores idle, and allocate only a few tasks to each of the 16 cores on the first processor. Also, is there any way we could have more evenly distributed the load across the 20 cores that were being used without the product edition upgrade? The flip side of that question is what did the product upgrade do that caused SQL Server to start evenly distributing the load across all of the cores that it recognized? Thanks to any insight to answer these questions and/or links that might help me better understand how to make sense of what was happenings.

• Slow network file transfer (under 20KB/s) on newly built x64 Win7

  - by Mangoshake

  I am getting <20KB/s for local network file transfer. If I transfer a very small file (less than 100KB) it would start quickly then slow down to <20KB/s. all subsequently network file transfer would be slow, a reboot is needed to reset this. If I transfer a large file it would be stuck on calculating for a long time and then begin with <20KB/s immediately. This is a newly built desktop running Windows 7 x64 SP1. Realtek gigabit LAN from the motherboard (ASRock Extreme3 gen3). Problematic speed is observed on the private LAN, both through ethernet and WiFi. The Router is D-Link DIR-655. Remote Differential Compression is off. Drivers are up-to-date from ASRock's website. I have tested network file transfer to and from another Windows 7 laptop and a MacBook Pro, so I am fairly certain it is the desktop's problem. The slow speed only happens with one direction also, outbound from the desktop, regardless of whether I initiate the file transfer action from the origin or the destination. Inbound network file transfer and internet speeds are fine, so I don't think this is a hardware issue. I am getting 74.8MB/s internet upload speed from speedtest.net (http://www.speedtest.net/result/1852752479.png). Inbound network file transfer I can get around 10-15MB/s. I am hoping this community has some insight for me to troubleshoot this. I don't see anything obviously related from the Event Viewer, and beyond that I just don't know where else to look. Any suggestions are greatly appreciated, thank you in advance.

• Transfering call asterisk to different context

  - by Necronet

  I have a Small and basic PBX, and with two contexts wich basicly are sales and supervisor both have different roles and privileges. I notice that it is possible to transfer call from the same context but it have been imposible to transfer anything to another context. Any insight, i am kinda a rookie on asterisk but currently there is no one else in charge... Thanks Edit This is the extension.conf [supervisor] include => from-internal exten => _40XX,1,Answer exten => _40XX,n,Set(calltime=${STRFTIME(${EPOCH},,%C%y%m%d.%H.%M.%S)}) exten => _40XX,n,Set(CALLEDNUMBER=${EXTEN}) exten => _40XX,n,MixMonitor(/tmp/Para_${CALLEDNUMBER}-${calltime}-De_${CALLERID(num)}.wav) exten => _40XX,n,Dial(SIP/${EXTEN},40,TtRr) exten => _40XX,n,Hangup [sales] include => out-trunksip exten => _41XX,1,Answer exten => _41XX,n,Set(calltime=${STRFTIME(${EPOCH},,%C%y%m%d.%H.%M.%S)}) exten => _41XX,n,Set(CALLEDNUMBER=${EXTEN}) exten => _41XX,n,MixMonitor(/tmp/Para_${CALLEDNUMBER}-${calltime}-De_${CALLERID(num)}.wav) exten => _41XX,n,Dial(SIP/${EXTEN},40,TtRr) exten => _41XX,n,Hangup and the sip.conf looks like this: [supervisor] username=sales secret=ASUPERSECRETPASSWORD type=peer ..... context=supervisor mailbox=supervisor [sales] username=sales secret=ASUPERSECRETPASSWORD type=peer ..... context=sales mailbox=sales What do you suggest in order to get the supervisor with the same privileges that he already has and the sales been able to transfer calls to him

• Configure PEAR on CentOS 6 and PLESK

  - by RCNeil

  I'm hoping to get a little assistance with configuring PEAR to work properly. I have a PHP file that's calling PEAR's mail and mail-mime files, and I believe I am missing some steps because I keep getting the very common Warning: include_once(Mail.php): failed to open stream: No such file or directory Warning: include_once(Mail_Mime/mime.php): failed to open stream: No such file or directory It is installed - Installed packages, channel pear.php.net: ========================================= Package Version State Archive_Tar 1.3.7 stable Console_Getopt 1.2.3 stable Mail 1.2.0 stable Mail_Mime 1.8.3 stable PEAR 1.9.4 stable Structures_Graph 1.0.4 stable XML_RPC 1.5.4 stable XML_Util 1.2.1 stable And according to this TUT, I need to configure it appropriately in each vhost. I have already gone through and adjusted the php.ini file, but when the TUT speaks of the php_admin_value open_basedir "/var/www/vhosts/example.com/httpdocs:/tmp:/usr/share/pear:/local/PEAR" in my /var/www/vhosts/example.com/conf/httpd.include file I kind of get lost. There are several httpd.include files in that directory, all preceded with very long numerical strings. All I want to do is have an email attachment in my form.... Any insight or similar experiences shared would be greatly appreciated.

• LDAP Authentication fails with 500 or 401 depending on bind for Apache2

  - by Erik

  I'm setting up LDAP authentication for our Subversion repository hosted through Apache on a RHEL 5 system. I run into two different issues when I try to authenticate against Active Directory. <Location /svn/> Dav svn SvnParentPath /srv/subversion SVNListParentPath On AuthType Basic AuthName "Subversion Repository" AuthBasicProvider ldap AuthLDAPBindDN "cn=userfoo,ou=Service Accounts,ou=User Accounts,dc=my,dc=example,dc=com" AuthLDAPBindPassword "mypass" AuthLDAPUrl "ldap://my.example.com:389/ou=User Accounts,dc=my,dc=example,dc=com?sAMAccountName?sub?(objectClass=user)" NONE Require valid-user </Location> If I use the above configuration it continually prompts me with the Basic prompt and I have to eventually select Cancel, which returns a 401 (Authorization Required). If I comment out the bind parts it returns 500 (Internal Server Error), griping that authentication failed: [Mon Nov 02 12:00:00 2009] [warn] [client x.x.x.x] [10744] auth_ldap authenticate: user myuser authentication failed; URI /svn [ldap_search_ext_s() for user failed][Operations error] When I perform the bind using ldapsearch and filter for a simple attribute it returns correctly: ldapsearch -h my.example.com -p 389 -D "cn=userfoo,ou=Service Accounts,ou=User Accounts,dc=my,dc=example,dc=com" -b "ou=User Accounts,dc=my,dc=example,dc=com" -w - "&(objectClass=user)(cn=myuser)" sAMAccountName Unfortunately I have no control or insight into the AD part of the system, only the RHEL server. Does anyone know what the hang up is here?
