• CPU Temperature sensor wrong?

  - by Matias Nino

  Everest Ultimate is suddenly telling me that the CPU temperature (and core temps) for my E6850 Core 2 Duo is 72 degrees Celsius. When I stress-test the machine, the temp goes up to 91 degrees and the CPU actually throttles. System remains stable though. For over a year now, my CPU has run very cool (40's) with a large commercial copper heatsink/fan that I bought separately. To top it off, I removed the cover of the box and felt the cpu heatsink and it wasn't even warm. Is there such a thing as a CPU temp sensor showing the wrong readings? Any tips would help. UPDATE #1 Temp is also just as high in BIOS. So that leads me to believe it's a CPU seating issue (even though I used thermal paste to seat it two years ago when I built the machine) UPDATE #2 Well. I removed the heatsink and cleaned off the original thermal paste (which was somewhat crusty). I polished the surface, re-applied some new paste, and reseated the heat sink. After powering it up, there was no noticeable change in the temp - ideling at 74. Ran the stress test and it went up to 94 degrees before being 100% throttled. I let it sit at 94 degrees for 20 minutes straight and the computer didn't even flinch. I then immediately shut it off and opened the case and felt around. The heatsink was completely cold to the touch. Even the copper rods were cold. The area near contact with the CPU was slightly warm but not hot to touch. Then I ran REALTEMP, which is supposedly more accurate and it told me the CPU was at 104 degrees. (LOL) At this point, I'm thinking no doubt the cpu's sensor is wrong. Sidenote: the BIOS has the latest version so no option to flash there. Reverting hasn't been known to help from what I've read. What pisses me off is the false temps force the CPU to artificially throttle from 3GHz down to 2GHz and my CPU fan is cranking at full force all the time. Should I call intel and tell them to send me another E6850? SOLUTION UPDATE I switched the processor out with another one and got the same obscene temperatures with the new processor followed by a heatsink that was cool to touch. My suspicion in the heatsink was suddenly renewed. I swapped it out with the stock heatsink/fan and lo and behold the temperatures returned to the normal 35C-50C. Even though the thermal paste was visibly flattened out every time I removed it, it looks like the heatsink was still not pressing hard enough on the CPU to effectively conduct the heat. The heatsink is a Masscool 8Wa741, which screws into a standard position on a mount on the back of the MOBO. Only thing I can surmise after 2 years of use was that, over time, the heatsink pressure on the CPU gave way until the heat began to be ineffectively conducted. Lessons learned: Intel CPU's can run SUPER HOT (upwards of 95C) and still be stable. Heatsink's need to be VERY firmly pressed against the CPU to conduct heat.

• Cannot ping Localhost so I can't shutdown Tomcat

  - by gav

  Hi, I installed Tomcat 6 using the tar-ball via wget. Startup of the server is fine but on shutdown I get a timeout exception. root@88:/usr/local/tomcat/logs# /usr/local/tomcat/bin/shutdown.sh Using CATALINA_BASE: /usr/local/tomcat Using CATALINA_HOME: /usr/local/tomcat Using CATALINA_TMPDIR: /usr/local/tomcat/temp Using JRE_HOME: /usr Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar 30-Mar-2010 17:33:41 org.apache.catalina.startup.Catalina stopServer SEVERE: Catalina.stop: java.net.ConnectException: Connection timed out at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) ... I read that this might be because I have a firewall blocking incoming connections on the shutdown port (8005). I have a default Ubuntu 9.04 installation running on a VPS with no rules in my iptables. How can I tell if that port is blocked? How can I check that the server is listening for connections on 8005? Bizarrely pinging localhost or the IP of my server fails from the server itself, whereas pinging the IP of my server from another machine succeeds. -------- EDIT -------- (In reply to Davey) Thanks for all the tips and suggestions! netstat -nlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:8005 0.0.0.0:* LISTEN 9611/java tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN 28505/mysqld tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 9611/java tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN ...

• SQL Server Issue: Could not allocate space for object ... primary filegroup is full

  - by Luke

  Trying to figure out a problem at an office that has SQL Server 2005 installed on Windows SBS Server 2008. Here's the setup: It's an office, and the person who set this all up is nowhere to be found. I'm the best hope they have... One of the programs they use on a workstation gives them an error of "Could not allocate space for object 'Billing' in database "MyDatabase" because primary filegroup is full" when trying to save an entry in their software. I searched around for hours, looking for possible solutions. One was to check for available disk space, and another was to defrag. I checked the hard drives on the server, and there is plenty of space free. I also defragged, which may have helped the problem somewhat. It's hard to say, because it seems like with the nature of the error, if you try over and over you might get it to actually save. My next step was to try to see if autogrowth was enabled on the database. This would seem to be a likely / possible solution, but I can't access the database! If I run the SQL Management Studio, I can log in as my Windows user and view the list of databases. However, if I try to do anything (actually view the database, view the properties, add or edit users), I get errors that I don't have permission. For what it's worth, I also tried runing Management Studio as Administrator, in case that would help. No difference, though. Now, what I'm guessing is going on -- from my limited knowledge of SQL and from reading online -- is that though I'm logged in as a Windows administrator, that account does NOT have SQL access. I do see a list of SQL users, including SA, but I again don't have permission to add one or to change the password on an existing one. And nobody at the office has any idea what the SQL passwords could be. So... here's my thinking thus far: 1 - The "Could not allocate" error likely points to a database that needs to be allowed to autogrow. Especially since I verified there is plenty of free space and the HD has been defragmented. 2 - Enabling autogrow would be very easy to do if I had the proper access within SQL Management Stuido. That leads me to this link: http://blogs.technet.com/b/sqlman/archive/2011/06/14/tips-amp-tricks-you-have-lost-access-to-sql-server-now-what.aspx It sounds like it's a step-by-step guide for giving me the access I need to SQL. I'm guessing that if I followed this guide, I would be able to then log in to the SQL server via Management Studio with the proper permissions, and would be able to enable autogrow (or simply view the status of the existing database), and hopefully solve the "Could not allocate space" problem! So I guess I have a few questions: 1 - Would you guys agree with my "diagnosis"? Think I'm barking up the right tree? 2 - Is there any risk at all in hurting / disabling / wrecking the current SQL database or setup with me going through the guide to regain SQL access? I understand that per the guide, I would have to temporarily shut down SQL, so obviously it wouldn't be accessible during that time. But it wouldn't be worth the risk if there's a chance I could mess anything up... Like I said, the workstations ARE currently accessing the database somehow, but nobody knows with what login info or anything. Basically, it's set up, it works (usually), but if they had to reload the software, nobody would know how. Any feedback would be appreciated!! The problem is such that it's not an emergency for them, but an annoyance. If I could fix it, it would be wonderful. But if not, I think they'll manage, especially as they are going to eventually stop using this software. Thank you so much for your time! Luke

• Single-Signon options for Exchange 2010

  - by freiheit

  We're working on a project to migrate employee email from Unix/open-source (courier IMAP, exim, squirrelmail, etc) to Exchange 2010, and trying to figure out options for single-signon for Outlook Web Access. So far all the options I've found are very ugly and "unsupportable", and may simply not work with Forefront. We already have JA-SIG CAS for token-based single-signon and Shibboleth for SAML. Users are directed to a simple in-house portal (a Perl CGI, really) that they use to sign in to most stuff. We have an HA OpenLDAP cluster that's already synchronized against another AD domain and will be synchronized with the AD domain Exchange will be using. CAS authenticates against LDAP. The portal authenticates against CAS. Shibboleth authenticates with CAS but pulls additional data from LDAP. We're moving in the direction of having web services authenticate against CAS or Shibboleth. (Students are already on SAML/Shibboleth authenticated Google Apps for Education) With Squirrelmail we have a horrible hack linked to from that portal page that authenticates against CAS, gets your original plaintext password (yes, I know, evil), and gives you an HTTP form pre-filled with all the necessary squirrelmail login details with javaScript onLoad stuff to immediately submit the form. Trying to find out exactly what is possible with Exchange/OWA seems to be difficult. "CAS" is both the acronym for our single-signon server and an Exchange component. From what I've been able to tell there's an addon for Exchange that does SAML, but only for federating things like free/busy calendar info, not authenticating users. Plus it costs additional money so there's no way to experiment with it to see if it can be coaxed into doing what we want. Our plans for the Exchange cluster involve Forefront Threat Management Gateway (the new ISA) in the DMZ front-ending the CAS servers. So, the real question: Has anybody managed to make Exchange authenticate with CAS (token-based single-signon) or SAML, or with something I can reasonably likely make authenticate with one of those (such as anything that will accept apache's authentication)? With Forefront? Failing that, anybody have some tips on convincing OWA Forms Based Authentication (FBA) into letting us somehow "pre-login" the user? (log in as them and pass back cookies to the user, or giving the user a pre-filled form that autosubmits like we do with squirrelmail). This is the least-favorite option for a number of reasons, but it would (just barely) satisfy our requirements. From what I hear from the guy implementing Forefront, we may have to set OWA to basic authentication and do forms in Forefront for authentication, so it's possible this isn't even possible. I did find CasOwa, but it only mentions Exchange 2007, looks kinda scary, and as near as I can tell is mostly the same OWA FBA hack I was considering slightly more integrated with the CAS server. It also didn't look like many people had had much success with it. And it may not work with Forefront. There's also "CASifying Outlook Web Access 2", but that one scares me, too, and involves setting up a complex proxy config, which seems more likely to break. And, again, doesn't look like it would work with Forefront. Am I missing something with Exchange SAML (OWA Federated whatchamacallit) where it is possible to configure to do user authentication and not just free/busy access authorization?

• Can I get advice on my nginx configuration (as a proxy in front of Jira and Confluence)?

  - by Nate

  I was wondering if I could get some advice on my nginx configuration. The config seems to be working, but I'm unsure if I'm doing everything properly. The basic idea is to have a Jira and Confluence server (in separate Tomcat instances) running on the same machine, with nginx in front to handle SSL for both. I want only SSL connections to be made to Jira/Confluence. Jira is running on 127.0.0.1:9090 and Confluence on 127.0.0.1:8080. Here is my nginx.conf, any advice or tips would be greatly appreciated. user nginx; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] $request ' '"$status" $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; # Load config files from the /etc/nginx/conf.d directory include /etc/nginx/conf.d/*.conf; # Our self-signed cert ssl_certificate /etc/ssl/certs/fissl.crt; ssl_certificate_key /etc/ssl/private/fissl.key; # redirect non-ssl Confluence to ssl server { listen 80; server_name confluence.example.com; rewrite ^(.*) https://confluence.example.com$1 permanent; } # redirect non-ssl Jira to ssl server { listen 80; server_name jira.example.com; rewrite ^(.*) https://jira.example.com$1 permanent; } # # The Confluence server # server { listen 443; server_name confluence.example.com; ssl on; access_log /var/log/nginx/confluence.access.log main; error_log /var/log/nginx/confluence.error.log; location / { proxy_pass http://127.0.0.1:8080; proxy_set_header X-Forwarded-Proto https; proxy_set_header Host $http_host; } error_page 404 /404.html; location = /404.html { root /usr/share/nginx/html; } redirect server error pages to the static page /50x.html error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } } # # The Jira server # server { listen 443; server_name jira.example.com; ssl on; access_log /var/log/nginx/jira.access.log main; error_log /var/log/nginx/jira.error.log; location / { proxy_pass http://127.0.0.1:9090/; proxy_set_header X-Forwarded-Proto https; proxy_set_header Host $http_host; } error_page 404 /404.html; location = /404.html { root /usr/share/nginx/html; } # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } } }

• Performance issues when using SSD for a developer notebook (WAMP/LAMP stack)?

  - by András Szepesházi

  I'm a web application developer using my notebook as a standalone development environment (WAMP stack). I just switched from a Core2-duo Vista 32 bit notebook with 2Gb RAM and SATA HDD, to an i5-2520M Win7 64 bit with 4Gb RAM and 128 GB SDD (Corsair P3 128). My initial experience was what I expected, fast boot, quick load of all the applications (Eclipse takes now 5 seconds as opposed to 30s on my old notebook), overall great experience. Then I started to build up my development stack, both as LAMP (using VirtualBox with a debian guest) and WAMP (windows native apache + mysql + php). I wanted to compare those two. This still all worked great out, then I started to pull in my projects to these stacks. And here came the nasty surprise, one of those projects produced a lot worse response times than on my old notebook (that was true for both the VirtualBox and WAMP stack). Apache, php and mysql configurations were practically identical in all environments. I started to do a lot of benchmarking and profiling, and here is what I've found: All general benchmarks (Performance Test 7.0, HDTune Pro, wPrime2 and some more) gave a big advantage to the new notebook. Nothing surprising here. Disc specific tests showed that read/write operations peaked around 380M/160M for the SSD, and all the different sized block operations also performed very well. Started apache performance benchmarking with Apache Benchmark for a small static html file (10 concurrent threads, 500 iterations). Old notebook: min 47ms, median 111ms, max 156ms New WAMP stack: min 71ms, median 135ms, max 296ms New LAMP stack (in VirtualBox): min 6ms, median 46ms, max 175ms Right here I don't get why the native WAMP stack performed so bad, but at least the LAMP environment brought the expected speed. Apache performance measurement for non-cached php content. The php runs a loop of 1000 and generates sha1(uniqid()) inisde. Again, 10 concurrent threads, 500 iterations were used for the benchmark. Old notebook: min 0ms, median 39ms, max 218ms New WAMP stack: min 20ms, median 61ms, max 186ms New LAMP stack (in VirtualBox): min 124ms, median 704ms, max 2463ms What the hell? The new LAMP performed miserably, and even the new native WAMP was outperformed by the old notebook. php + mysql test. The test consists of connecting to a database and reading a single record form a table using INNER JOIN on 3 more (indexed) tables, repeated 100 times within a loop. Databases were identical. 10 concurrent threads, 100 iterations were used for the benchmark. Old notebook: min 1201ms, median 1734ms, max 3728ms New WAMP stack: min 367ms, median 675ms, max 1893ms New LAMP stack (in VirtualBox): min 1410ms, median 3659ms, max 5045ms And the same test with concurrency set to 1 (instead of 10): Old notebook: min 1201ms, median 1261ms, max 1357ms New WAMP stack: min 399ms, median 483ms, max 539ms New LAMP stack (in VirtualBox): min 285ms, median 348ms, max 444ms Strictly for my purposes, as I'm using a self contained development environment (= low concurrency) I could be satisfied with the second test's result. Though I have no idea why the VirtualBox environment performed so bad with higher concurrency. Finally I performed a test of including many php files. The application that I mentioned at the beginning, the one that was performing so bad, has a heavy bootstrap, loads hundreds of small library and configuration files while initializing. So this test does nothing else just includes about 100 files. Concurrency set to 1, 100 iterations: Old notebook: min 140ms, median 168ms, max 406ms New WAMP stack: min 434ms, median 488ms, max 604ms New LAMP stack (in VirtualBox): min 413ms, median 1040ms, max 1921ms Even if I consider that VirtualBox reached those files via shared folders, and that slows things down a bit, I still don't see how could the old notebook outperform so heavily both new configurations. And I think this is the real root of the slow performance, as the application uses even more includes, and the whole bootstrap will occur several times within a page request (for each ajax call, for example). To sum it up, here I am with a brand new high-performance notebook that loads the same page in 20 seconds, that my old notebook can do in 5-7 seconds. Needless to say, I'm not a very happy person right now. Why do you think I experience these poor performance values? What are my options to remedy this situation?

• How to setup stunnel so that gmail can use my own smtp server to send messages.

  - by igorhvr

  I am trying to setup gmail to send messages using my own smtp server. I am doing this by using stunnel over a non-ssl enabled server. I am able to use my own smtp client with ssl enabled just fine to my server. Unfortunately, however, gmail seems to be unable to connect to my stunnel port. Gmail seems to be simply closing the connection right after it is established - I get a "SSL socket closed on SSL_read" on my server logs. On gmail, I get a "We are having trouble authenticating with your other mail service. Please try changing your SSL settings. If you continue to experience difficulties, please contact your other email provider for further instructions." message. Any help / tips on figuring this out will be appreciated. My certificate is self-signed - could this perhaps be related to the problem I am experiencing?

• Hanging of host network connections when starting KVM guest on bridge

  - by Chris Phillips

  Hi, I've a KVM system upon which I'm running a network bridge directly between all VM's and a bond0 (eth0, eth1) on the host OS. As such, all machines are presented on the same subnet, available outside of the box. The bond is doing mode 1 active / passive, with an arp_ip_target set to the default gateway, which has caused some issues in itself, but I can't see the bond configs mattering here myself. I'm seeing odd things most times when I stop and start a guest on the platform, in that on the host I lose network connectivity (icmp, ssh) for about 30 seconds. I don't lose connectivity on the other already running VM's though... they can always ping the default GW, but the host can't. I say "about 30 seconds" but from some tests it actually seems to be 28 seconds usually (or at least, I lose 28 pings...) and I'm wondering if this somehow relates to the bridge config. I'm not running STP on the bridge at all, and the forwarding delay is set to 1 second, path cost on the bond0 lowered to 10 and port priority of bond0 also lowered to 1. As such I don't think that the bridge should ever be able to think that bond0 is not connected just fine (as continued guest connectivity implies) yet the IP of the host, which is on the bridge device (... could that matter?? ) becomes unreachable. I'm fairly sure it's about the bridged networking, but at the same time as this happens when a VM is started there are clearly loads of other things also happening so maybe I'm way off the mark.

• Debian virtual memory reaching limit

  - by Gregor

  As a relative newbie to systems, I inherited a Debian server and I've noticed that virtual memory is very high (around 95%!). The server has been running slow for around 6 months, and I was wondering if any of you had any tips on things I could try, particularly on freeing up memory. The server hosts various websites and also a Postit email server. Here are the details: Operating system Debian Linux 5.0 Webmin version 1.580 Time on system Thu Apr 12 11:12:21 2012 Kernel and CPU Linux 2.6.18-6-amd64 on x86_64 Processor information Intel(R) Core(TM)2 Duo CPU E7400 @ 2.80GHz, 2 cores System uptime 229 days, 12 hours, 50 minutes Running processes 138 CPU load averages 0.10 (1 min) 0.28 (5 mins) 0.36 (15 mins) CPU usage 14% user, 1% kernel, 0% IO, 85% idle Real memory 2.94 GB total, 1.69 GB used Virtual memory 3.93 GB total, 3.84 GB used Local disk space 142.84 GB total, 116.13 GB used Free m output: free -m total used free shared buffers cached Mem: 3010 2517 492 0 107 996 -/+ buffers/cache: 1413 1596 Swap: 4024 3930 93 Top output: top - 11:59:57 up 229 days, 13:38, 1 user, load average: 0.26, 0.24, 0.26 Tasks: 136 total, 2 running, 134 sleeping, 0 stopped, 0 zombie Cpu(s): 3.8%us, 0.5%sy, 0.0%ni, 95.0%id, 0.7%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 3082544k total, 2773160k used, 309384k free, 111496k buffers Swap: 4120632k total, 4024712k used, 95920k free, 1036136k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 28796 www-data 16 0 304m 68m 6188 S 8 2.3 0:03.13 apache2 1 root 15 0 10304 592 564 S 0 0.0 0:00.76 init 2 root RT 0 0 0 0 S 0 0.0 0:04.06 migration/0 3 root 34 19 0 0 0 S 0 0.0 0:05.67 ksoftirqd/0 4 root RT 0 0 0 0 S 0 0.0 0:00.00 watchdog/0 5 root RT 0 0 0 0 S 0 0.0 0:00.06 migration/1 6 root 34 19 0 0 0 S 0 0.0 0:01.26 ksoftirqd/1 7 root RT 0 0 0 0 S 0 0.0 0:00.00 watchdog/1 8 root 10 -5 0 0 0 S 0 0.0 0:00.12 events/0 9 root 10 -5 0 0 0 S 0 0.0 0:00.00 events/1 10 root 10 -5 0 0 0 S 0 0.0 0:00.00 khelper 11 root 10 -5 0 0 0 S 0 0.0 0:00.02 kthread 16 root 10 -5 0 0 0 S 0 0.0 0:15.51 kblockd/0 17 root 10 -5 0 0 0 S 0 0.0 0:01.32 kblockd/1 18 root 15 -5 0 0 0 S 0 0.0 0:00.00 kacpid 127 root 10 -5 0 0 0 S 0 0.0 0:00.00 khubd 129 root 10 -5 0 0 0 S 0 0.0 0:00.00 kseriod 180 root 10 -5 0 0 0 S 0 0.0 70:09.05 kswapd0 181 root 17 -5 0 0 0 S 0 0.0 0:00.00 aio/0 182 root 17 -5 0 0 0 S 0 0.0 0:00.00 aio/1 780 root 16 -5 0 0 0 S 0 0.0 0:00.00 ata/0 782 root 16 -5 0 0 0 S 0 0.0 0:00.00 ata/1 783 root 16 -5 0 0 0 S 0 0.0 0:00.00 ata_aux 802 root 10 -5 0 0 0 S 0 0.0 0:00.00 scsi_eh_0 803 root 10 -5 0 0 0 S 0 0.0 0:00.00 scsi_eh_1 804 root 10 -5 0 0 0 S 0 0.0 0:00.00 scsi_eh_2 805 root 10 -5 0 0 0 S 0 0.0 0:00.00 scsi_eh_3 1013 root 10 -5 0 0 0 S 0 0.0 49:27.78 kjournald 1181 root 15 -4 16912 452 448 S 0 0.0 0:00.05 udevd 1544 root 14 -5 0 0 0 S 0 0.0 0:00.00 kpsmoused 1706 root 13 -5 0 0 0 S 0 0.0 0:00.00 kmirrord 1995 root 18 0 193m 3324 1688 S 0 0.1 8:52.77 rsyslogd 2031 root 15 0 48856 732 608 S 0 0.0 0:01.86 sshd 2071 root 25 0 17316 1072 1068 S 0 0.0 0:00.00 mysqld_safe 2108 mysql 15 0 320m 72m 4368 S 0 2.4 1923:25 mysqld 2109 root 18 0 3776 500 496 S 0 0.0 0:00.00 logger 2180 postgres 15 0 99504 3016 2880 S 0 0.1 1:24.15 postgres 2184 postgres 15 0 99504 3596 3420 S 0 0.1 0:02.08 postgres 2185 postgres 15 0 99504 696 628 S 0 0.0 0:00.65 postgres 2186 postgres 15 0 99640 892 648 S 0 0.0 0:01.18 postgres

• Symantec Protection Suite and System Recovery 2011 Desktop Edition

  - by rihatum

  I am re-posting this as my previous question was being treated as if I am "Shopping or seeking Product Recommendations" even though I was NOT - BTW they have deleted my comments too which were not offensive in nature. anyway - I have re-phrased some parts of my question and I hope SF Admins "Do Not Modify / Edit" this one - will be most grateful for that. I have a lot of respect for the People who visit this SITE and help others ! Just To clarify : Just to go by SF rules - I am not seeking someone to Design this solution, I am simply seeking real world examples, experiences, technical expert opinions / suggestions, any tips or tricks they may have or any problems they may have faced while doing something similar above with these products. I am also not asking for Capacity Planning for Storage, We have done some research and I am seeking Expert Assurance / Suggestions. We (our company) are planning to deploy Symantec Endpoint Protection and Symantec Desktop Recovery 2011 Desktop Edition to our 3000 - 4000 workstations (Windows7 32 and 64) with a few 100s with Windows XP 32/64 Bit. I have read the implementation guide for SEP and have read tech-notes for Desktop Recovery 2011. Our team have planned to deploy this as follows : 1 x dedicated SQL 2008R2 for Symantec Endpoint Protection (Instead of using the Embedded Database) 1 x Dedicated SQL 2008R2 for Symantec Desktop Recovery 2011 (Instead of using the Embedded Database) 1 x Dedicated W2K8 R2 Box for the SEPM (Symantec Endpoint Protection Manager - Mgmt. APP) 1 x Dedicated W2K8 R2 Box for the Symantec Desktop Recovery 2011 Management Application Agent Deployment : As per Symantec Documentation for both of the above, an agent can be pushed via the Mgmt. Application (provided no firewalls are blocking ports required etc. - we have Windows firewall disabled already). Server Hardware : Per SQL Server : 16GB RAM + SAS DISKS + Dual XEON, RAID-10 for the SQL DB or I can always mount a LUN from our existing Hitachi or EMC SAN. SEPM Server : 16GB RAM + SAS DISKS + DUAL XEON System Recovery MGMT SERVER : 16GB RAM + SAS DISKS + DUAL XEON Above is the initial plan we have for 3000 - 4000 client workstation (Windows) Now my Questions :-) a) If we had these users distributed amongst two sites with AD DC / GC in each site, How would I restrict SEPM and Desktop Mgmt. solution to only check for users in their respective site ? b) At present all users are under one building but we are going to move some dept. to a new location (with dedicated connectivity), How would we control which SEPM / MGMT Server is responsible for which site ? c) We have netbackup in our environment backing up other servers, I am planning to protect these 4 (2 x SQL, 1 x SEPM, 1 x System Recovery Mgmt. Server) via netbackup or I can use System recovery 2011 server edition on all 4 of these boxes as well. (License is not an issue as we have the complete symantec portfolio included in our license). d) Now - Saving Desktop backups - What strategies have you implemented ? Any best practice recommendation for a large user base ? I was thinking to either mount a LUN from our Hitachi SAN on the Symantec Recovery Server itself or backup to the users hard drive locally and then copy it over to a network location ? Suggestions welcome :-) If you have anything to add / correct - that will be really helpful before diving into the actual implementation phase. Will be most grateful with your suggestions, recommendations and corrections with above - Many Thanks !

• Using different SSDs types (not only SATA based) as system drive

  - by Hubert Kario

  Currently I have a Thinkpad X61s and want to make it both a bit faster and a bit more power efficient. For that reason I thought that adding SSD drive would make most sense. Unfortunately, because of financial reasons, buying SSD of over 200GB capacity is out of reach for me (not only it would be worth more than the rest of the laptop, but also I currently have a 500GB drive in it, so even such a drive would be kind of a downgrade for me). During preliminary testing with a cheap Transcend 4GB Class 6 (14MiB/s streaming, 9MiB/s random read) card I experienced boot times to be reduced by half so putting the OS only on it would already would be an improvement. Unfortunately, my system now is about 11GiB in size so anything less than 16GB would be constraining. In this laptop I can connect additional drives on at least 5 different ways: using SATA-ATA converter caddy in the X6 Ultrabase using internal mini PCIe slot using integrated SDHC slot using CardBus (a.k.a PCMCIA or PC Card) slot using USB Thankfully, because I use only Linux on this PC the bootability of them is irrelevant as I can put the /boot partition on internal HDD and / on any of the above mentioned Flash memories (as I already did for the SDHC test). From what I was able to research and from my own experience those options come with rather big downsides or other problems: SATA-ATA caddy It has three downsides: I have to carry the Ultrabse with me at all times (it's not really inconvenient, but those grams do add) and couldn't disconnect it when I want to disconnect the battery It makes the bay unusable for the optical drive and occasional quick access to other hard drives the only caddies I could buy have rather flaky controllers in them so putting my OS on it would hamper its stability Internal mini PCIe slot This would be an ideal solution, if only I could find real PCIe SSDs, not only devices that could talk only SATA or ATA over PCIe mechanical connection (the ones used in Dell Mini or Asus EEE). Theoretically Samsung did release such devices but I couldn't find them in retail anywhere. Integrated SDHC slot It's a nice solution with a single drawback: the fastest 16GB SDHC card on the market can only do around 35MiB/s read and 15MiB/s write while still costing like a normal 40GB SATA SSD that's 10 times faster. Not really cost-effective. CardBus (a.k.a PCMCIA or PC Card) slot Those cards are much faster than the SDHC option (there are ones that can do well over 50MiB/s read in benchmarks) and from what I could find the PCMCIA controller in my laptop does support UDMA so it should be able to deliver comparable speeds. They still cost similarly to SD cards but at least they provide streaming performance comparable to my current HDD. USB That's the worst option. Not only is it limited to 20-30MiB/s by the interface itself the drive would stick out of the laptop so it's a big no no. The question As such I think that going the "CF in a CardBus adapter" route will be the best option. My question is: did anyone try using CF cards in CardBus adapters as system drives with Linux on Thinkpad laptops? Laptops in general? What was the real-world performance? I don't have any CF cards so I can't check how well does it work with suspend/resume, or whatever it's easy to make it work in initramfs (I'm using ArchLinux and SD card was trivial — add 3 modules in single config line and rebuilding initramfs) so any tips/gotchas on this are welcome as well.

• Outlook Web Access, reverse proxy and browser

  - by M'vy

  Hi SF'ers! We recently moved an exchange server behind a reverse proxy due to the loss of a public IP. I've managed to configure the reverse proxy (httpd proxy_http). But there is a problem for the SSL configuration. When accessing the OWA interface with Firefox, all is ok and working. When accessing with MSIE or Chrome, they do not retrieve the good SSL Certificate. I think this is due to the multiples virtual host for httpd. Is there a workaround to make sure MSIE/Chrome request the certificate for the good domain name like FF does? Already tested with the SSL virtual host : SetEnvIf User-Agent ".*MSIE.*" value BrowserMSIE Header unset WWW-Authenticate Header add WWW-Authenticate "Basic realm=exchange.domain.com" A: ProxyPreserveHost On also: BrowserMatch ".*MSIE.*" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 Or: SetEnvIf User-Agent ".*MSIE.*" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 And lots of ProxyPassand ProxyReversePath on /exchweb /exchange /public etc... And it still don't seem to work. Any clue? Thanks.

• Vim: Context sensitive code completion for PHP

  - by eddy147

  Vim gives me too much options when I use code completion. In a class, and type $class- it gives me about a zillion options, so not only from the class itself but also from php, all globals ever created, in short: a mess. I only want to have the options from the class itself (or the parent subtype class it extends from), so context or scope sensitive code completion, just like Netbeans for example. How can I do that? My current configuration is this: I am using ctags, and created 1 ctags file for our (big) application in the root. This is the .ctags file I used to create the ctags file: -R -h ".php" --exclude=.svn --languages=+PHP,-JavaScript --tag-relative=yes --regex-PHP=/abstract\s+class\s+([^ ]+)/\1/c/ --regex-PHP=/interface\s+([^ ]+)/\1/c/ --regex-PHP=/(public\s+|static\s+|protected\s+|private\s+)\$([^ \t=]+)/\2/p/ --regex-PHP=/const\s+([^ \t=]+)/\1/d/ --regex-PHP=/final\s+(public\s+|static\s+|abstract\s+|protected\s+|private\s+)function\s+\&?\s*([^ (]+)/\2/f/ --PHP-kinds=+cdf --fields=+iaS This is the .vimrc file: " autocomplete funcs and identifiers for languages autocmd FileType php set omnifunc=phpcomplete#CompletePHP autocmd FileType python set omnifunc=pythoncomplete#Complete autocmd FileType javascript set omnifunc=javascriptcomplete#CompleteJS autocmd FileType html set omnifunc=htmlcomplete#CompleteTags autocmd FileType css set omnifunc=csscomplete#CompleteCSS autocmd FileType xml set omnifunc=xmlcomplete#CompleteTags autocmd FileType php set omnifunc=phpcomplete#CompletePHP autocmd FileType c set omnifunc=ccomplete#Complete " exuberant ctags " the magic is the ';' at end. it will make vim tags file search go up from current directory until it finds one. set tags=projectrootdir/tags; map <F8> :!ctags " TagList " :tag getUser => Jump to getUser method " :tn (or tnext) => go to next search result " :tp (or tprev) => to to previous search result " :ts (or tselect) => List the current tags " => Go back to last tag location " +Left click => Go to definition of a method " More info: " http://vimdoc.sourceforge.net/htmldoc/tagsrch.html (official documentation) " http://www.vim.org/tips/tip.php?tip_id=94 (a vim tip) let Tlist_Ctags_Cmd = "~/bin/ctags" let Tlist_WinWidth = 50 map <F4> :TlistToggle<cr> "see http://vim.wikia.com/wiki/Make_Vim_completion_popup_menu_work_just_like_in_an_IDE " will change the 'completeopt' option so that Vim's popup menu doesn't select the first completion item, but rather just inserts the longest common text of all matches :set completeopt=longest,menuone " will change the behavior of the <Enter> key when the popup menu is visible.

• Set up lnux box for hosting a-z [apache mysql php ssl]

  - by microchasm

  I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP: To upgrade PHP to the latest version, I had to look to another repo outside CentOS. IUS looks great and I'm happy I found it! cd /tmp #wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm #rpm -Uvh epel-release-1-1.ius.el5.noarch.rpm #wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-4.ius.el5.noarch.rpm #rpm -Uvh ius-release-1-4.ius.el5.noarch.rpm yum list | grep -w \.ius\.

I will keep editing this as I make progress. Any tips on how to Configure Virtualhosts for SSL, setting up a CA, setting up SFTP with openSSH, or anything else would be appreciated.

• "The server closed the connection without sending any data"

  - by Toby

  Server setup The problem Diagnostic information What I've tried Specific Help needed 1. I have the following server setup: Debian Squeeze Linux 2.6.32-5-amd64 Apache2-mpm-prefork 2.2.16-6+squeeze10 PHP 5.3.3-7+squeeze14 This server is protected with the Suhosin Patch 0.9.9.1 Max Requests Per Child: 0 - Keep Alive: on - Max Per Connection: 100 Timeouts Connection: 300 - Keep-Alive: 15 Loaded Modules core mod_log_config mod_logio prefork http_core mod_so mod_alias mod_auth_basic mod_auth_digest mod_authn_file mod_authz_default mod_authz_groupfile mod_authz_host mod_authz_user mod_cgi mod_deflate mod_dir mod_env mod_mime mod_negotiation mod_php5 mod_reqtimeout mod_rewrite mod_setenvif mod_ssl mod_status Wordpress 3.4.2 (Upgrading to 3.5 soon :) 2. The problem When I restart the server (sudo shutdown -r now), going to any website page results in the following error from the web browser (in this case, Google Chrome, but other browsers also show the same error). This error can also occur an hour or so after all is working ok, seemingly randomly, which is my biggest concern as it means my server is not reliable: No data received Unable to load the web page because the server sent no data. Here are some suggestions: Reload this web page later. Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data. 3. Diagnostic information The apache error log contains the folowing entries: [Fri Dec 14 22:23:27 2012] [notice] child pid 1955 exit signal Floating point exception (8) [Fri Dec 14 22:23:27 2012] [notice] child pid 1956 exit signal Floating point exception (8) [Fri Dec 14 22:23:29 2012] [notice] child pid 1957 exit signal Floating point exception (8) [Fri Dec 14 22:23:30 2012] [notice] child pid 1958 exit signal Floating point exception (8) [Fri Dec 14 22:23:32 2012] [notice] child pid 1959 exit signal Floating point exception (8) [Fri Dec 14 22:23:32 2012] [notice] child pid 1960 exit signal Floating point exception (8) [Fri Dec 14 22:23:34 2012] [notice] child pid 1961 exit signal Floating point exception (8) [Fri Dec 14 22:23:34 2012] [notice] child pid 1962 exit signal Floating point exception (8) 4. What I've tried a) I can 'fix' the website temporarily by resetting the server twice (resetting it once does not work) using the following commands. NB: the 'reload' option does not work, I have to use restart twice. However, the error can reoccur sometime later. sudo /etc/init.d/apache2 restart sudo /etc/init.d/apache2 restart b) I have tried disabling suhosin by uninstalling php5-suhosin, but a php info page still shows "This server is protected with the Suhosin Patch 0.9.9.1". I have tried putting Suhosin into simulation mode by creating a file /etc/php5/apache2/conf.d/suhosin.ini containing: [suhosin] suhosin.simulation = On The php info page shows the suhosin.ini file in the list of "Additional .ini files parsed" but the php info page still shows "This server is protected with the Suhosin Patch 0.9.9.1" c) Increasing the PHP memory limit In /etc/php5/apache2/ : ; Maximum amount of memory a script may consume (128MB) ; http://php.net/memory-limit memory_limit = 512M d) Disabling all Wordpress plugins, and going back to the default theme. 5. Specific help needed I would very much like help in debugging what is going on here. I am not sure how to determine what processes are in the Apache error log which are exiting "[notice] child pid 1955 exit signal Floating point exception (8)", or what is causing them to exit. And whether suhosin is part of the problem (and how to disable it if it is). Thank you in advance for any advice or tips you can offer in helping me debug this.

• Windows 7 disk errors after a few hours of runtime

  - by GFK

  I'm having trouble understanding what is going on with my work PC. Whenever I boot it, it runs fine for a while, then starts to randomly show disk errors. The displayed error often contains the message "not enough storage is available to process this command", although depending on the application that fails it can be different. This has happened for weeks now and is getting worse. This is what troubles me: It never seems to impact critical parts of the system (no BSOD, no freeze). Only some applications seem impacted, refusing to function correctly after a while: Outlook 2010 cannot download RSS feeds anymore, Firefox 6 or IE9 cannot download anything bigger than 3MB without failing, Windows Update fails, all msi installers fail, Visual Studio 2010 starts failing in weird manners... It only happens after a while using it (typically 3 hours, but it seems that installing a program or compiling several times makes it shorter) Rebooting solves it (temporarily). The system: The OS is Windows 7 Pro Spanish SP1, 32 bits The system is an HP Compaq 6000 Pro with 4 GB memory (only 3.4GB usable since the system is 32bit), one 500GB hard drive. Installed applications include: Visual Studio 2010, SQL Server 2008 R2, VMWare Workstation 7, Microsoft Security Essentials, Office 2010. Shutting down all related services and processes doesn't seem to change anything. The diagnostics I've run so far: Hard drive : 465GB, 165GB free Process Explorer : physical and virtual memory seem ok (pagefile is 5.3GB, physical memory usage 70%, system commit 39%) Windows Memory diagnostic tool: OK CHKDSK returned: 488282111 KB total disk space. 281668248 KB in 265779 files. 150188 KB in 62949 indexes. 0 KB in bad sectors. 571755 KB in use by the system. The log file has occupied 65536 kilobytes. 205891920 KB available on disk. For non-spanish speakers, that means all ok. SMART diagnostic tools (DiskCheckup) report all values normal. temperatures are in the normal range (HWinfo). The event viewer doesn't seem to contain any significant message. ran CCleaner 3, without any noticeable effect. I was thinking about some file number limit (between Visual Studio projects and other applications, there are around 300.000 files on the hard drive), but I couldn't find any. It's possible there is something related with the use of the temporary folders (it's the only explanation I have for why applications fail but Windows doesn't), but I cannot confirm that. Only thing I cannot find out is if chkdsk reporting 65MB for the log is normal. It seems since Vista it always reports this. Any other cleaning/diagnostic tool you might know of? Edit: I ran several other tools since I first published the question: Seagate SeaTools (the HD manufacturer's analysis tool): complete test run OK. Intel Rapid 10.1 (the HD controller manufacturer's troubleshooting tool): the HD's ok.

No luck. Also, I found out often the error is "not enough storage is available to process this command". Searching on the internet, I found an old troubleshooting tip (setting a registry key to raise the IRP stack limit, whatever it is) which did not change anything.

• Network update solutions for a company of ~20 (5 local, 15 remote)?

  - by Margaret

  Hi all This is probably going to be a bit up in the air, because we're still in the "reaching towards solutions" phase, but I figured I'd see what you guys had to say. Plus I honestly know very little about systems and what is good and bad pratice. My organisation has always more or less worked on the concept of local machines; since it primarily employed contractors who were working from home, each of those people was largely responsible for their own machine and backup procedures and the like. We're now expanding, though we're still reasonably small (we're up to about 20 staff members). Most people still work remotely, but we have a central office where about five people are working. But we're getting large enough that we're starting to think it would be a good idea to have a central file server, and things like that - if someone gets hit by a bus, we want someone else to know where to look for the files to continue their work. A lot of the people who work for us remotely work on projects for other companies as well, so I don't want to force them to log in to our server whenever they're on a network. But I do want to make connection to be as painless as possible to do so, to improve utilisation. The other thing is that we're getting more people who would like to remote into the office server and do their work there. Our current remote connection application is an SSH install that allows people access to the network; the problem is, it's a black box to me, and I've never understood how to even connect to it (despite supposedly being de facto sysadmin). Thus far I've been able to bounce questions about how to get it working to the guy who does know it well, but he's leaving the company soon. So we probably need a solution for this that I actually understand. We were knocking around the idea of implementing a VPN with some form of remote desktop, and someone mentioned that this was largely a matter of purchasing a router capable of it; I'm not sure of the truth of that statement. This is what we have in the office: Two shiny new i7 servers, each running Windows Server 2008. Precise eventual layout is still being debated, a little, but the current suggestion is that one is primary database crunching, while the other is a warm backup of the databases, along with running Reporting Services. They currently have SQL Server 2008 installed on them, which is being connected to via the 'sa' account. We're hoping to make each person use their own account (preferably one tied to the 'central' password we set up, so we can use Windows Authentication). An older server, running XP Pro, that we are currently using as a test bed for a project that requires access to older versions of software. This machine is also being used to take backups, but I'm thinking of moving that functionality elsewhere. A spare desktop from a guy who left the company (XP Pro). We're thinking of bumping up the hard disk space and using it as the magical file server that's going to solve one particular everything. Assorted desktops, laptops, etc, at least one for each person in the office (mix of Win XP and Win 7; occasionally a person who normally works remotely might drop in to the office and bring a laptop bearing Vista, but it's pretty rare). All are set up as local user accounts at the moment; I don't know if it's the best arrangement. Purchasing more hardware is not a big problem, but we figure we might as well make use of what we've got first. Is Active Directory a big magic wand that's going to solve all the world's problems? Is there some other arrangement we should be looking to instead?

They can reach any site on the real Internet. The same is true of the real machines on the network. The biggest puzzle perhaps is that the W8 VM actually DOES reach some of the virtual hosts. It does NOT reach site2, site6 and site 9, all of which have this minimal .htaccess file. .htaccess file <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{HTTP_HOST} !^www\. RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L] </IfModule> Adding this file to any of the virtual hosts that do work on the W8 VM will break the site (only for W8 VM, not the XP VM's) and require a cache flush on the W8 VM before it will see the site again after deleting the file. Regardless of whether a .htaccess file exists or not, no machine on the same LAN can access anything other than the XAMPP home page via IP. Even with hosts files on all machines. I can ping any virtual host from any machine on the network and get a response from the correct IP address. I can't see anything in out Netgear router that might prevent one machine from reaching the other. Besides, once the local hosts file resolves to an ip address that's all that goes out onto the local network. I've gone through an extensive number of posts on both SO and as the result of Google searches. I can't say that I have found anything definitive anywhere.

• Usage of IcmpSendEcho2 with an asynchronous callback

  - by Ben Voigt

  I've been reading the MSDN documentation for IcmpSendEcho2 and it raises more questions than it answers. I'm familiar with asynchronous callbacks from other Win32 APIs such as ReadFileEx... I provide a buffer which I guarantee will be reserved for the driver's use until the operation completes with any result other than IO_PENDING, I get my callback in case of either success or failure (and call GetCompletionStatus to find out which). Timeouts are my responsibility and I can call CancelIo to abort processing, but the buffer is still reserved until the driver cancels the operation and calls my completion routine with a status of CANCELLED. And there's an OVERLAPPED structure which uniquely identifies the request through all of this. IcmpSendEcho2 doesn't use an OVERLAPPED context structure for asynchronous requests. And the documentation is unclear excessively minimalist about what happens if the ping times out or fails (failure would be lack of a network connection, a missing ARP entry for local peers, ICMP destination unreachable response from an intervening router for remote peers, etc). Does anyone know whether the callback occurs on timeout and/or failure? And especially, if no response comes, can I reuse the buffer for another call to IcmpSendEcho2 or is it forever reserved in case a reply comes in late? I'm wanting to use this function from a Win32 service, which means I have to get the error-handling cases right and I can't just leak buffers (or if the API does leak buffers, I have to use a helper process so I have a way to abandon requests). There's also an ugly incompatibility in the way the callback is made. It looks like the first parameter is consistent between the two signatures, so I should be able to use the newer PIO_APC_ROUTINE as long as I only use the second parameter if an OS version check returns Vista or newer? Although MSDN says "don't do a Windows version check", it seems like I need to, because the set of versions with the new argument aren't the same as the set of versions where the function exists in iphlpapi.dll. Pointers to additional documentation or working code which uses this function and an APC would be much appreciated. Please also let me know if this is completely the wrong approach -- i.e. if either using raw sockets or some combination of IcmpCreateFile+WriteFileEx+ReadFileEx would be more robust.

• nhibernate mapping: A collection with cascade="all-delete-orphan" was no longer referenced

  - by Chev

  Hi All I am having some probs with my fluent mappings. I have an entity with a child collection of entities i.e Event and EventItems for example. If I set my cascade mapping of the collection to AllDeleteOrphan I get the following error when saving a new entity to the DB: NHibernate.HibernateException : A collection with cascade="all-delete-orphan" was no longer referenced by the owning entity instance: Core.Event.EventItems If I set the cascade to All it works fine? Below are my classes and mapping files: public class EventMap : ClassMap<Event> { public EventMap() { Id(x => x.Id, "Id") .UnsavedValue("00000000-0000-0000-0000-000000000000") .GeneratedBy.GuidComb(); Map(x => x.Name); HasMany(x => x.EventItems) .Inverse() .KeyColumn("EventId") .AsBag() .Cascade.AllDeleteOrphan(); } } public class EventItemMap : SubclassMap<EventItem> { public EventItemMap() { Id(x => x.Id, "Id") .UnsavedValue("00000000-0000-0000-0000-000000000000") .GeneratedBy.GuidComb(); References(x => x.Event, "EventId"); } } public class Event : EntityBase { private IList<EventItem> _EventItems; protected Event() { InitMembers(); } public Event(string name) : this() { Name = name; } private void InitMembers() { _EventItems = new List<EventItem>(); } public virtual EventItem CreateEventItem(string name) { EventItem eventItem = new EventItem(this, name); _EventItems.Add(eventItem); return eventItem; } public virtual string Name { get; private set; } public virtual IList<EventItem> EventItems { get { return _EventItems.ToList<EventItem>().AsReadOnly(); } protected set { _EventItems = value; } } } public class EventItem : EntityBase { protected EventItem() { } public EventItem(Event @event, string name):base(name) { Event = @event; } public virtual Event Event { get; private set; } } Pretty stumped here. Any tips greatly appreciated. Chev

• WPF CommandParameter is NULL first time CanExecute is called

  - by Jonas Follesø

  I have run into an issue with WPF and Commands that are bound to a Button inside the DataTemplate of an ItemsControl. The scenario is quite straight forward. The ItemsControl is bound to a list of objects, and I want to be able to remove each object in the list by clicking a Button. The Button executes a Command, and the Command takes care of the deletion. The CommandParameter is bound to the Object I want to delete. That way I know what the user clicked. A user should only be able to delete their "own" objects - so I need to do some checks in the "CanExecute" call of the Command to verify that the user has the right permissions. The problem is that the parameter passed to CanExecute is NULL the first time it's called - so I can't run the logic to enable/disable the command. However, if I make it allways enabled, and then click the button to execute the command, the CommandParameter is passed in correctly. So that means that the binding against the CommandParameter is working. The XAML for the ItemsControl and the DataTemplate looks like this: <ItemsControl x:Name="commentsList" ItemsSource="{Binding Path=SharedDataItemPM.Comments}" Width="Auto" Height="Auto"> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <Button Content="Delete" FontSize="10" Command="{Binding Path=DataContext.DeleteCommentCommand, ElementName=commentsList}" CommandParameter="{Binding}" /> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> So as you can see I have a list of Comments objects. I want the CommandParameter of the DeleteCommentCommand to be bound to the Command object. So I guess my question is: have anyone experienced this problem before? CanExecute gets called on my Command, but the parameter is always NULL the first time - why is that? Update: I was able to narrow the problem down a little. I added an empty Debug ValueConverter so that I could output a message when the CommandParameter is data bound. Turns out the problem is that the CanExecute method is executed before the CommandParameter is bound to the button. I have tried to set the CommandParameter before the Command (like suggested) - but it still doesn't work. Any tips on how to control it. Update2: Is there any way to detect when the binding is "done", so that I can force re-evaluation of the command? Also - is it a problem that I have multiple Buttons (one for each item in the ItemsControl) that bind to the same instance of a Command-object? Update3: I have uploaded a reproduction of the bug to my SkyDrive: http://cid-1a08c11c407c0d8e.skydrive.live.com/self.aspx/Code%20samples/CommandParameterBinding.zip
