  • FFmpeg extract clip - stream frame rate differs from container frame rate (x264, aac)

    - by fideli
    Summary H.264 video seems to have a really high frame rate that requires a scaling factor to the applied to the duration of video that I'm trying to extract (900x lower). Body I'm trying to extract a clip from a movie that I have in MP4 format (created using Handbrake). After trying mencoder and VLC, I decided to give FFmpeg a shot since it was the least troublesome when it came to copying the codecs. That is, compared to mencoder and VLC, the resulting file was still playable in QuickTime (I know about Perian, etc, I'm just trying to learn how all this works). Anyway, my command was as follows: ffmpeg -ss 01:15:51 -t 00:05:59 -i outofsight.mp4 \ -acodec copy -vcodec copy clip.mp4 During the copy, The following comes up: Seems stream 0 codec frame rate differs from container frame rate: 45000.00 (45000/1) -> 25.00 (25/1) Input #0, mov,mp4,m4a,3gp,3g2,mj2, from outofsight.mp4': Duration: 01:57:42.10, start: 0.000000, bitrate: 830 kb/s Stream #0.0(und): Video: h264, yuv420p, 720x384, 25 tbr, 22500 tbn, 45k tbc Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16 Output #0, mp4, to 'out.mp4': Stream #0.0(und): Video: libx264, yuv420p, 720x384, q=2-31, 90k tbn, 22500 tbc Stream #0.1(eng): Audio: libfaac, 48000 Hz, stereo, s16 Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 2591 fps=2349 q=-1.0 size= 8144kB time=101.60 bitrate= 656.7kbits/s … Instead of a 5:59 duration clip, I get the entire rest of the movie. So, to test this, I ran the ffmpeg command with -t 00:00:01. What I got was exactly a 15:00 minute clip. So I did some black box engineering and decided to scale my -t option by calculating what value to enter given that 1 second was interpreted as 900 s. For my desired 359 s clip, I calculated 0.399 s and so my ffmpeg command became: ffmpeg -ss 01:15.51 -t 00:00:00.399 -i outofsight.mp4 \ -acodec copy -vcodec copy clip.mp4 This works, but I have no idea why the duration is scaled by 900. Investigating further, each ffmpeg run has the line: Seems stream 0 codec frame rate differs from container frame rate: 45000.00 (45000/1) -> 25.00 (25/1) 45000/25 = 1800. Must be a relation somewhere. Somehow, the obscenely high frame rate is causing issues with the timing. How is that frame rate so high? The best part about this is that the resulting clip.mp4 has the exact same feature (due to the copied video codec), and taking further clips from this needs the same scaling for the -t duration option. Therefore, I've made it available for anyone willing to check this out.

  • Does likewise-open > version 5.4 contain CIFS support?

    - by Ben Andken
    I'm trying to get the CIFS server working in likewise-open. I've found this set of instructions and everything seems to work until I try to connect ([url]http://www.likewise.com/resources/documentation_library/manuals/cifs/likewise-cifs-smb-file-server-guide.html#id2765992):[/url] 1.6. Build and Configure a Standalone Likewise-CIFS Server This section demonstrates how to build and configure a standalone instance of Likewise-CIFS from the command line. The following procedure assumes that you want to set up Likewise-CIFS on a Linux server to share files with Windows computers in a network without Active Directory. This procedure also assumes you know how to build Linux applications from their source code and then install them. Download Likewise-CIFS from its open source git location: $ git clone git://git.likewiseopen.org/ Download, build, and install the following tools. The tools listed are known to work, but earlier or later versions might work as well. Also, instead of downloading the tools, you might be able to install them on your platform with apt-get or some other means. http://ftp.gnu.org/gnu/autoconf/autoconf-2.65.tar.gz http://ftp.gnu.org/gnu/automake/automake-1.9.6.tar.gz http://ftp.gnu.org/gnu/libtool/libtool-2.2.6a.tar.gz http://pkgconfig.freedesktop.org/releases/pkg-config-0.23.tar.gz gcc --version 3.x or greater Build Likewise-CIFS: $ cd likewise-open $ build/mkcomp --debug all Install Likewise-CIFS: $ sudo su $ cd staging/install-root $ tar cf - . | (cd / && tar xvf -) Make sure Samba is not running: $ /etc/init.d/smb stop Make sure SELinux is either disabled or set to permissive. Make sure the ports required by Likewise are open. For a list of ports that Likewise uses, see the Likewise Open Installation and Administration Guide. Configure Likewise Open: $ /etc/init.d/lwsmd start $ for i in /etc/likewise/*.reg; do /opt/likewise/bin/lwregshell upgrade $i; done $ /etc/init.d/lwsmd stop $ /etc/init.d/lwsmd start $ /opt/likewise/bin/lwsm start srvsvc $ /opt/likewise/bin/domainjoin-cli configure --enable nsswitch Add a user account to the local Likewise provider database. In the following example, substitute the account name that you want for newuser. $ /opt/likewise/bin/lw-add-user --home /home/newuser --shell /bin/bash newuser Successfully added user newuser Enable the user and set the password: $ /opt/likewise/bin/lw-mod-user --enable-user --set-password newuser New Password: ********** Successfully modified user newuser Look up new user's identity as follows. Substitute the value from the command hostname -s for the hostname. Keep in mind that Likewise truncates a hostname longer than 15 characters to the first 15 characters of the string. % id hostname\\newuser uid=2000(HOSTNAME\newuser) gid=1800(HOSTNAME\Likewise Users) groups=1800(HOSTNAME\Likewise Users) context=system_u:system_r:unconfined_t:s0 Make a CIFS directory for the user: mkdir /lwcifs/newuser chown 2000:1800 /lwcifs/newuser From a Windows computer, map the Likewise-CIFS drive share: Computer->Map Network Drive... Folder: \\IP_hostname\c$ Click "Finish" Username: hostname\newuser Password: user_password The last step fails when I try to connect. I've tried with Windows XP Pro and Windows 7 Pro. The rest of the directions only appear to work for version 5.4 (the one that shipped with 10.04). For 12.04, version 6.1 is the only one available and it doesn't appear to have the srvsvc module mentioned in these instructions. Is CIFS support dropped in the 6.1 version of likewise-open?

  • Kernel Mode Rootkit

    - by Pajarito
    On the other 3 computers in my family, I believe that we have a kernel-mode rootkit for windows. It appears that the same rootkit is on all of them. We think. We changed all the important passwords from my computer, running linux right now. On all of the infected computers is Symantic Endpoint Protection, because it's free from the university where my mom and dad work. In my opinion symantec is a piece of crap, seeing as it didn't even manager to delete the tracking cookies it found when I tried it on my own computer. The Computers and their set-ups: Computer A: Vista Business; symantec antivirus. runs it as admin, no password. IE8. no other security software other than what comes with windows. IE8 security settings the default Computer B: XP Home Premium; symantec antivirus. runs as normal user, no password, admin account with weak password, spybot, uses IE8 with default settings, sometimes Firefox Computer C: XP Home Premium; symantec antivirus. runs as normal user, no password, admin account with weak password, uses IE8 with default settings, no other security programs except what came with windows This is what's happening. Cut and pasted from my dad's forum post. -- When I scanned my laptop (Dell XPS M1330 with Windows Vista Small Business), Symantec Endpoint Protection hangs for a while, perhaps 10 seconds or so, on some of the following files 9129837.exe, hide_evr2.sys, VirusRemoval.vbs, NewVirusRemoval.vbs, dll.dll, alsmt.ext, and _epnt.sys. It does this if a run a scan that I set up to run on a new thumbnail drive and it does this even if the thumbnail is not plugged in. It doesn't seem to do this if I scan only the C: drive. I've check for problems with symantec endpoint protection and also with Microsoft Security Essentials and Malwarebytes Anti-Malware. They found nothing and I can't find anything by searching for hidden files. Next I tried microsoft's rootkitrevealer. It (rootkitrevealer) finds 279660 (or so) discrepancies and the interface is so glitchy after that I can't really figure out what is going on. The screen is squirrely. The rootkitrevealer pulls up many files in the folder \programdata\applicationdata and there are numberous appended \applicationdata on the end of that as well. -- As you can see, what we did was install MSE and MBAM and scan with both of them. Nothing but a tracking cookie. Then I took over and ran rootkitrevealer.exe from MicroSoft from a flash drive. It found a bunch of discrepancies, but only about 20 or so where security related, the rest being files that you just couldn't see from Windows Explorer. I couldn't see whether of not the files list above, the ones that the scan was hanging on, where in the list. The other thing is, I have no idea what to do about the things the scan comes up with. Then we checked the other computers and they do the same thing when you scan with Symantec. The people at the university seen to think that dad might not have a virus, but 2 of the computers slowed down noticably AND IE8 started acting all funny. None of my family is very computer oriented, and 2 of the possible causes for the rootkit are: -My dad bought a new flash drive, which shipped with a data security executable on it -My dad has to download lots of articles for his work Those are the only things that stand out, but it could have been anything. We are currently backing up our data, and I'll post again after trying IceSword 1.22. I just looked at my dad's forum topic, and someone recommended GMER. I'll try that too.

  • Integrating HP Systems Insight Manager into an existing environment

    - by ewwhite
    I'm working with an environment that spans multiple data centers/sites and consists primarily of HP ProLiant servers (G5-G7) running Linux. The mix is 30% RHEL/CentOS, the rest are Gentoo :(. I also have a few dozen virtual machines running back-office and Windows servers on VMWare ESX hosts. I run OpenNMS to pull SNMP data from the various server nodes and networking devices. While OpenNMS works wonderfully for up/down, thresholds and notifications, it's native handling of traps is a little rough and the graphs are not particularly pretty. I use Orca/RRD graphs for performance trending and nice graphs. I'm tasked with inventorying the environment and wanted to come up with a clean way to organize server information. Since my environment is mostly HP, I've been playing with HP Systems Insight Manager as a way to extract server data and to deploy HP health/monitoring packages and firmware. The Gentoo systems eventually have to be converted to CentOS, so getting a quick assessment of what hardware is where would be great. Although I've read through a few hundred pages of HP manuals, I'm having a difficult time understanding how to get HP SIM to do what I want, though. My main problems are: I have about 40 subnets to deal with; 98% connected with private lines to facilities across the globe. I don't want to initiate an HP SIM discovery only to pull back every piece of intermediate networking hardware and equipment from all of the locations. I'd like this to focus on the servers. I have OpenNMS configured to accept traps. I don't want HP SIM to duplicate that effort. It seems like the built-in software deployment tool wants to overwrite the trapsink parameters for the systems it encounters during discovery. I have about 10 administrative username/password combinations in use across this infrastructure. Is there a more efficient way to get HP SIM to do the discovery or break discovery into manageable chunks? In terms of general workflow, do people typically install the HP Management Agents during the initial OS deployment (e.g. kickstart post script) or afterwards from HP SIM? Is HP SIM too thick/fat to be an inventory tool? I can't tell if it's meant to be used standalone or alongside other monitoring products. Since the majority of the systems I'm trying to track are those running Gentoo (in order to plan the move to CentOS), is there any way for HP SIM to extract system model information from them ( like dmidecode)? I have systems here where I may have an SSH key established, but not direct user or login access. Is there a way for me to import an SSH private/public key pair into HP SIM to reach out to the servers that can't accept standard credentials? There are a handful of sites where I have inconsistent access or have a double-NAT situation. I may be able to poke a server, but it may not be able to find its way back to the management system. Is there a workaround for this? The certificate configuration for HP SIM seems complicated. What is the preferred setup for trust between systems? I'd also appreciate any notes or recommendations to using this product. Or if there's a better way to do this, I'd like to know.

  • Ubuntu: Move fsbackup backups to Amazon S3

    - by Alexander Gladysh
    I have a legacy server (Ubuntu 9.10 Karmic x86), where previous admin set up backups with fsbackup. This server lives in a VPS (under some kind of Xen), and it is low on HDD space (16 GB total). Now it came to a point, where fsbackup backups take more space than the rest of data in the system. The filesystem is 100% filled, and I already cleaned up all that I could, aside from actual backups. I do not have any experience managing fsbackup, and I do not want to break or lose the backups. Googling fsbackup gives surprisingly low quality results... Here is how my backups look like: $ sudo ls -lh /var/archives total 8.1G -rw-rw---- 1 root root 318 2011-01-06 06:26 myserver-20110106.md5 -rw-rw---- 1 root root 258 2011-01-07 06:26 myserver-20110107.md5 -rw-rw---- 1 root root 318 2011-01-08 06:26 myserver-20110108.md5 -rw-rw---- 1 root root 318 2011-01-09 06:26 myserver-20110109.md5 -rw-rw---- 1 root root 346 2011-01-10 06:43 myserver-20110110.md5 -rw-rw---- 1 root root 14M 2011-01-06 06:26 myserver-all-mysql-databases.20110106.sql.bz2 -rw-rw---- 1 root root 14M 2011-01-07 06:26 myserver-all-mysql-databases.20110107.sql.bz2 -rw-rw---- 1 root root 14M 2011-01-08 06:26 myserver-all-mysql-databases.20110108.sql.bz2 -rw-rw---- 1 root root 14M 2011-01-09 06:26 myserver-all-mysql-databases.20110109.sql.bz2 -rw-rw---- 1 root root 862 2011-01-10 06:43 myserver-all-mysql-databases.20110110.sql.bz2 -rw-rw---- 1 root root 827K 2011-01-03 06:25 myserver-etc.20110103.master.tar.gz -rw-rw---- 1 root root 16K 2011-01-06 06:25 myserver-etc.20110106.tar.gz -rw-rw---- 1 root root 16K 2011-01-07 06:25 myserver-etc.20110107.tar.gz -rw-rw---- 1 root root 16K 2011-01-08 06:25 myserver-etc.20110108.tar.gz -rw-rw---- 1 root root 16K 2011-01-09 06:25 myserver-etc.20110109.tar.gz -rw-rw---- 1 root root 827K 2011-01-10 06:25 myserver-etc.20110110.master.tar.gz -rw------- 1 root root 36K 2011-01-10 06:25 myserver-etc.incremental.bin -rw-rw---- 1 root root 29M 2011-01-03 06:25 myserver-home.20110103.master.tar.gz -rw-rw---- 1 root root 11K 2011-01-06 06:25 myserver-home.20110106.tar.gz -rw-rw---- 1 root root 14K 2011-01-07 06:25 myserver-home.20110107.tar.gz -rw-rw---- 1 root root 11K 2011-01-08 06:25 myserver-home.20110108.tar.gz -rw-rw---- 1 root root 11K 2011-01-09 06:25 myserver-home.20110109.tar.gz -rw-rw---- 1 root root 2.0M 2011-01-10 06:25 myserver-home.20110110.master.tar.gz -rw------- 1 root root 27K 2011-01-10 06:25 myserver-home.incremental.bin -rw-rw---- 1 root root 1.5G 2011-01-03 06:29 myserver-opt.20110103.master.tar.gz -rw-rw---- 1 root root 1.5M 2011-01-06 06:25 myserver-opt.20110106.tar.gz -rw-rw---- 1 root root 1.5M 2011-01-07 06:25 myserver-opt.20110107.tar.gz -rw-rw---- 1 root root 1.5M 2011-01-08 06:25 myserver-opt.20110108.tar.gz -rw-rw---- 1 root root 1.5M 2011-01-09 06:25 myserver-opt.20110109.tar.gz -rw-rw---- 1 root root 1.5G 2011-01-10 06:30 myserver-opt.20110110.master.tar.gz -rw------- 1 root root 201K 2011-01-10 06:30 myserver-opt.incremental.bin -rw-rw---- 1 root root 2.3G 2011-01-03 06:41 myserver-srv.20110103.master.tar.gz -rw-rw---- 1 root root 44M 2011-01-06 06:26 myserver-srv.20110106.tar.gz -rw-rw---- 1 root root 27M 2011-01-07 06:25 myserver-srv.20110107.tar.gz -rw-rw---- 1 root root 39M 2011-01-08 06:26 myserver-srv.20110108.tar.gz -rw-rw---- 1 root root 2.0M 2011-01-09 06:25 myserver-srv.20110109.tar.gz -rw-rw---- 1 root root 2.7G 2011-01-10 06:42 myserver-srv.20110110.master.tar.gz -rw------- 1 root root 3.4M 2011-01-10 06:42 myserver-srv.incremental.bin I'm thinking about moving backups to Amazon S3, but before that I have to free some space, so the server can work.

  • Improving TCP performance over a gigabit network with lots of connections and high traffic of small packets

    - by MinimeDJ
    I’m trying to improve my TCP throughput over a “gigabit network with lots of connections and high traffic of small packets”. My server OS is Ubuntu 11.10 Server 64bit. There are about 50.000 (and growing) clients connected to my server through TCP Sockets (all on the same port). 95% of of my packets have size of 1-150 bytes (TCP header and payload). The rest 5% vary from 150 up to 4096+ bytes. With the config below my server can handle traffic up to 30 Mbps (full duplex). Can you please advice best practice to tune OS for my needs?

  • Blocking 'good' bots in nginx with multiple conditions for certain off-limits URL's where humans can go

    - by Glenn Plas
    After 2 days of searching/trying/failing I decided to post this here, I haven't found any example of someone doing the same nor what I tried seems to be working OK. I'm trying to send a 403 to bots not respecting the robots.txt file (even after downloading it several times). Specifically Googlebot. It will support the following robots.txt definition. User-agent: * Disallow: /*/*/page/ The intent is to allow Google to browse whatever they can find on the site but return a 403 for the following type of request. Googlebot seems to keep on nesting these links eternally adding paging block after block: my_domain.com:80 - 66.x.67.x - - [25/Apr/2012:11:13:54 +0200] "GET /2011/06/ page/3/?/page/2//page/3//page/2//page/3//page/2//page/2//page/4//page/4//pag e/1/&wpmp_switcher=desktop HTTP/1.1" 403 135 "-" "Mozilla/5.0 (compatible; G ooglebot/2.1; +http://www.google.com/bot.html)" It's a wordpress site btw. I don't want those pages to show up, even though after the robots.txt info got through, they stopped for a while only to begin crawling again later. It just never stops .... I do want real people to see this. As you can see, google get a 403 but when I try this myself in a browser I get a 404 back. I want browsers to pass. root@my_domain:# nginx -V nginx version: nginx/1.2.0 I tried different approaches, using a map and plain old nono if's and they both act the same: (under http section) map $http_user_agent $is_bot { default 0; ~crawl|Googlebot|Slurp|spider|bingbot|tracker|click|parser|spider 1; } (under the server section) location ~ /(\d+)/(\d+)/page/ { if ($is_bot) { return 403; # Please respect the robots.txt file ! } } I recently had to polish up my Apache skills for a client where I did about the same thing like this : # Block real Engines , not respecting robots.txt but allowing correct calls to pass # Google RewriteCond %{HTTP_USER_AGENT} ^Mozilla/5\.0\ \(compatible;\ Googlebot/2\.[01];\ \+http://www\.google\.com/bot\.html\)$ [NC,OR] # Bing RewriteCond %{HTTP_USER_AGENT} ^Mozilla/5\.0\ \(compatible;\ bingbot/2\.[01];\ \+http://www\.bing\.com/bingbot\.htm\)$ [NC,OR] # msnbot RewriteCond %{HTTP_USER_AGENT} ^msnbot-media/1\.[01]\ \(\+http://search\.msn\.com/msnbot\.htm\)$ [NC,OR] # Slurp RewriteCond %{HTTP_USER_AGENT} ^Mozilla/5\.0\ \(compatible;\ Yahoo!\ Slurp;\ http://help\.yahoo\.com/help/us/ysearch/slurp\)$ [NC] # block all page searches, the rest may pass RewriteCond %{REQUEST_URI} ^(/[0-9]{4}/[0-9]{2}/page/) [OR] # or with the wpmp_switcher=mobile parameter set RewriteCond %{QUERY_STRING} wpmp_switcher=mobile # ISSUE 403 / SERVE ERRORDOCUMENT RewriteRule .* - [F,L] # End if match This does a bit more than I asked nginx to do but it's about the same principle, I'm having a hard time figuring this out for nginx. So my question would be, why would nginx serve my browser a 404 ? Why isn't it passing, The regex isn't matching for my UA: "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.30 Safari/536.5" There are tons of example to block based on UA alone, and that's easy. It also looks like the matchin location is final, e.g. it's not 'falling' through for regular user, I'm pretty certain that this has some correlation with the 404 I get in the browser. As a cherry on top of things, I also want google to disregard the parameter wpmp_switcher=mobile , wpmp_switcher=desktop is fine but I just don't want the same content being crawled multiple times. Even though I ended up adding wpmp_switcher=mobile via the google webmaster tools pages (requiring me to sign up ....). that also stopped for a while but today they are back spidering the mobile sections. So in short, I need to find a way for nginx to enforce the robots.txt definitions. Can someone shell out a few minutes of their lives and push me in the right direction please ? I really appreciate ANY response that makes me think harder ;-)

  • VirtualBox - Public Static IP for a Debian Guest on a Dedicated Server

    - by user86296
    Goal: I want to run a Debian-squeeze-Guest in VirtualBox and it's own public static ip. I found tons of threads about this topic, but all in all I'm now trying for 10 hours (reading the manual, the forums, trying to learn about networking concepts & commands) to give a Guest his own public static ip (so that the Guest is similar to a vServer you can order from a hosting company), but wasn't able to. Since I'm a big noob as far as networking stuff is concerned, I'm probably doing something wrong.(please bear with me :-) ) Situation: VirtualBox 4.0.10 (headless no gui) is running on a dedicated Debian-Server, the Guest OS is Debian as well. The server has a static ip and I ordered an additional ip for a VM. Problem description: Upto now I was able to use NAT to access the VM from the outside and to setup an internal network between several Guests and all of this worked very well. When setting NIC 1 to bridged and configuring a public static ip on the guest, the guest was unpingable. (neither from outside, nor from the host) I could connect to the guest via the internal network, from another vm, though. ( VBoxManage controlvm VMGuest nic1 bridged eth0 ) ( configuration attempt of static-ip on the guest '/etc/network/interfaces' is below) Please let me know what I'm doing wrong, or what I can try to get it to work, or if you need more info. I think I've read that with a current VirtualBox-version for bridged networking no special host-configuration is necessary, is that accurate, or might that be the problem? Additional Info Info I got from the hosting company about the additional IP Please note that you can use the IP address only for this server.

  • Ubuntu 12 crashed and took down network

    - by Leopd
    We recently set up a new Ubuntu 12.04LTS server on our network. It's not fully configured so it's not doing much beyond sshd and a default apache2 install. But this evening it appears to have crashed. It wasn't responding to the network or the keyboard. But the worst part is, it took down the entire network. My knowledge of the network stack below OSI layer 3 is very limited, so the rest confuses me. When this machine was physically connected to the network, no other machine could connect to the outside internet. When things were broken, running arp showed that our gateway's IP address (10.0.1.1) was listed as "invalid." Unplugging the server from the network fixed the problem, and plugging it back in broke it again. So the crashed server was advertising itself as owning the gateway's IP address? There's nothing at all in syslog during the time when it was causing problems. Any ideas about how to figure out what went wrong or what we can do to prevent it from happening again? I'm hesitant to even put the machine back on the network right now. Update ** It crashed again, and I ran tcpdump -penn arp (thanks bahamat!) for several minutes and got this...

It should DHCP to 10.0.3.3 Thanks for any help. This ARP stuff is all voodoo to me. Packets just go to IP addresses, right? ;)

  • Configuring Wireless on Cisco 851W

    Either a powersurge or something caused our router's configuration to get wiped, and our last backup was before the wireless network was setup. We have not been able to reconfigure the wireless since then, so was curious if anyone here would be able to determine what configuration is needed. We are using a Cisco 851W running 12.4(15)T9 We would like to use WPA encryption, and have it on the same network as the rest of the office network.

  • phpmyadmin login redirect fails with custom ssl port

    - by baraboom
    The server is running Ubuntu 10.10, Apache 2.2.16, PHP 5.3.3-1ubuntu9.3, phpMyAdmin 3.3.7deb5build0.10.10.1. Since this same server is also running Zimbra on port 443, I've configured apache to serve SSL on port 81. So far, I have one CMS script running on this virtual host successfully. However, when I access /phpmyadmin (set up with the default alias) on my custom ssl port and submit the login form, I am redirected to http://vhost.domain.com:81/index.php?TOKEN=foo (note the http:// instead of the https:// that the login url was using). This generates an Error 400 Bad Request complaining about "speaking plain HTTP to an SSL-enabled server port." I can then manually change the http:// to https:// in the URL and use phpmyadmin as expected. I was annoyed enough to spend an hour trying to fix it and now even more annoyed that I cannot figure it out. I've tried various things, including: Adding $cfg['PmaAbsoluteUri'] = 'https://vhost.domain.com:81/phpmyadmin/'; to the /usr/share/phpmyadmin/config.inc.php file but this did not correct the problem (even though /usr/share/phpmyadmin/libraries/auth/cookie.auth.lib.php looks like it should honor it and use it as the redirect). Adding $cfg['ForceSSL'] = 1; to the same config.inc.php but then apache spirals into an infinite redirect. Adding a rewrite rule to the vhost-ssl conf file in apache but I was unable to figure out the condition to use when http:// was present along with the correct ssl port of :81. Lots of googling. Here are the relevant Apache configuration pieces: /etc/apache2/ports.conf <IfModule mod_ssl.c> NameVirtualHost *:81 Listen 81 </IfModule> /etc/apache2/sites-enabled/vhost-nonssl <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName vhost.domain.com DocumentRoot /home/xxx/sites/vhost/html RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}:81%{REQUEST_URI} </Virtualhost> /etc/apache2/sites-enabled/vhost-ssl <VirtualHost *:81> ServerAdmin webmaster@localhost ServerName vhost.domain.com DocumentRoot /home/xxx/sites/vhost/html <Directory /> Options FollowSymLinks AllowOverride None AuthType Basic AuthName "Restricted Vhost" AuthUserFile /home/xxx/sites/vhost/.users Require valid-user </Directory> <Directory /home/xxx/sites/vhost/html/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> /etc/apache2/conf.d/phpmyadmin.conf Alias /phpmyadmin /usr/share/phpmyadmin (The rest of the default .conf truncated.) Everything in the apache config seems to work ok - the rewrite from non-ssl to ssl, the http authentication, the problem only happens when I am submitting the login form for phpmyadmin from https://vhost.domain.com:81/index.php. Other configs: The phpmyadmin config is completely default and the php.ini has only had some minor changes to memory and timeout limits. These seem to work fine, as mentioned, another php script runs with no problem and phpmyadmin works great once I manually enter in the correct schema after login. I'm looking for either a bandaid I can add to save me the trouble of manually entering in the https:// after login, a real fix that will make phpmyadmin behave as I think it should or some greater understanding of why my desired config is not possible.

  • How to stop Apache from crashing my entire server?

    - by CyberShadow
    I maintain a Gentoo server with a few services, including Apache. It's fairly low-end (2GB of RAM and a low-end CPU with 2 cores). My problem is that, despite my best efforts, an over-loaded Apache crashes the entire server. In fact, at this point I'm close to being convinced that Linux is a horrible operating system that isn't worth anyone's time looking for stability under load. Things I tried: Adjusting oom_adj for the root Apache process (and thus all its children). That had close to no effect. When Apache was overloaded it would bring the system to a grind, as the system paged out everything else before it got to kill anything. Turning off swap. Didn't help, it would unload memory paged to binaries of processes and other files on /, thus causing the same effect. Putting it in a memory-limited cgroup (limited to 512 MB of RAM, 1/4th of the total). This "worked", at least in my own stress tests - except the server keeps crashing under load (basically stalling all other processes, inaccessible via SSH, etc.) Running it with idle I/O priority. This wasn't a very good idea in the end, because it just caused the system load to climb indefinitely (into the thousands) with almost no visible effect - until you tried to access an unbuffered part of the disk. This caused the task to freeze. (So much for good I/O scheduling, eh?) Limiting the number of concurrent connections to Apache. Setting the number too low caused web sites to become unresponsive due to most slots being occupied with long requests (file downloads). I tried various Apache MPMs without much success (prefork, event, itk). Switching from prefork/event+php-cgi+suphp to itk+mod_php. This improved performance, but didn't solve the actual problem. Switching I/O schedulers (cfq to deadline). Just to stress this out: I don't care if Apache itself goes down under load, I just want the rest of my system to remain stable. Of course, having Apache recover quickly after a brief period of intensive load would be great to have, but one step at a time. Right now I am mostly dumbfounded by how can humanity, in this day and age, design an operating system where such a seemingly simple task (don't allow one system component to crash the entire system) seems practically impossible - or at least, very hard to do. Please don't suggest things like VMs or "BUY MORE RAM". Some more information gathered with a friend's help: The processes hang when the cgroup oom killer is invoked. Here's the call trace: [<ffffffff8104b94b>] ? prepare_to_wait+0x70/0x7b [<ffffffff810a9c73>] mem_cgroup_handle_oom+0xdf/0x180 [<ffffffff810a9559>] ? memcg_oom_wake_function+0x0/0x6d [<ffffffff810aa041>] __mem_cgroup_try_charge+0x32d/0x478 [<ffffffff810aac67>] mem_cgroup_charge_common+0x48/0x73 [<ffffffff81081c98>] ? __lru_cache_add+0x60/0x62 [<ffffffff810aadc3>] mem_cgroup_newpage_charge+0x3b/0x4a [<ffffffff8108ec38>] handle_mm_fault+0x305/0x8cf [<ffffffff813c6276>] ? schedule+0x6ae/0x6fb [<ffffffff8101f568>] do_page_fault+0x214/0x22b [<ffffffff813c7e1f>] page_fault+0x1f/0x30 At this point, the apache memory cgroup is practically deadlocked, and burning CPU in syscalls (all with the above call trace). This seems like a problem in the cgroup implementation...

  • My computer freezes irregurarly

    - by Manhim
    My computer started to freeze at irregular times for 3 weeks now. What happens My computer freezes, the video stops. (No graphic glitches, it just stops) Sound keeps playing up to some time (Usually 10-30 seconds) then stops playing. Sometimes, randomly, the screen on my G-15 keyboard flickers and I see caracters not at the right places. Usually happens for about 1-2 seconds and a bit before my computer freezes. I have to keep the power button pressed for 4 seconds to shut my computer down. I still hear my hard drives and fans working. Sometimes it works with no problems for a full day, some other times it just keeps freezing each time I restart my computer and I have to leave it for the rest of the day. Sometimes my mouse freezes for a fraction of a second (Like 0.01 to 0.2 seconds) quite randomly, usually before it freezes. No errors spotted by the "Action center" unlike when I had problems with my last video card on this system (Driver errors). My G-15 LCD screen also freezes. What I did so far I have had similar problems in the past and I had changed my hard drive (It was faulty), so I tested my software RAID-0 array and it was faulty so I changed it. (I reinstalled Windows 7 with this part). I also tested with unplugging my secondary hard drive. My CPU was running at about 100 degree Celsius, I removed the dust between the fans and the heatsink and it's now between 50-60. I ran a CPU stress-test and it didn't freeze during the tests (using Prime95 on all cores) Ran a memory test (using memtest86+) for a single pass and there were no errors. Ran a GPU stress test with ati-tools and furmark and it didn't freeze during the tests. (No artefacts either) I had troubles with my graphic card when I got it, but I think that it got fixed with a driver update. I checked the voltages in my BIOS setup and they all seemed ok (±0.2 I think). I have ran on the computer without problems with Fedora 15 on an external hard drive (Appart that it couldn't load Gnome 3 and was reverting to Gnome 2, didn't want to install drivers since I use it on multiple computers) I used it to backup my files from the raid array to my 1TB hard drive for the reinstallation of Windows. (So the crashes only happenned on Windows) [The external hard drive is plugged directly on a SATA port] I contacted EVGA (My graphic card vendor) and pointed them on this question, I'm looking for an answer. Ran sensors on Fedora 15 and got this output: http://pastebin.com/0BHJnAvu When it happens When I play video games (Mostly) When I play flash games (Second most) When I'm looking at my desktop background (It rarely happens when I have a window open, but it does, sometimes) Specs Windows Seven x64 Home Premium Motherboard: M2N-SLI Deluxe CPU: AMD Phenom 9950 x2 @ 2.6GHz Memory: Kingston 4x2GB Dual Channel (Pretty basic memory sticks) Hard drives: Was 2x250GB (Western digital caviar) in raid-0 + 1TB (WD caviar black), I replaced the raid array with a 750GB (WD caviar black) [Yes I removed the array from the raid configurations] 750W Power supply No overcloking. Ever. There have been some power-downs like 4-5 weeks ago, but the problem didn't start immediately after. (I wasn't home, so my computer got shut-down) My current to-try list Change the thermal paste on my CPU. Change my graphic card with a temporary one and stress the computer. Change my power supply. In this situation, how can I successfully pin-point the current hardware problem? (If it's a hardware problem) Because I don't really have the budget to just forget and replace everything. I also don't really have hardware to test-replace current hardware.

  • Determining the required depth and specifications for a server cabinet

    - by Bingu Bingme
    I'm trying to understand the considerations ("why") that go into determining the specifications ("what") for a rackmount server cabinet, in order to determine what sort of rack I should purchase for my home use. Since this is for home use, I won't be following certain best practices (eg. hot/cold aisle, not even air conditioning) and may be willing to sacrifice in various areas in order to reduce cost and footprint - but please advise if there are safety concerns or other considerations to note. The most basic specs for a server cabinet are the dimensions (external width x external depth x usable height). Width: commonly 600mm or 800mm (if the use case requires extra clearance around the sides, such as if there is lots of cabling). In my case and most common cases, I'm going to stick with 600mm. Height: Select a sufficiently tall rack to fit my equipment. But how much may I stuff into it? Eg, if there is a 15U rack, can I really populate it with 15U of servers, or should I leave 1U at top and bottom for air circulation? Depth: Racks commonly have external depth of 600mm (network equipment), 800mm, 1000mm, or even longer. I'm trying to see how to fit into the 800mm depth. With reference to http://www.server-racks.com/rack-mount-depth.html, I'm hoping to have the front and rear posts mounted ~ 28.5" (72cm) apart, which would leave only 8cm for front space and rear space. How much rear space (from rear posts to back of rack) do I really need? I won't use cable management arms, so can I mount a 72cm depth server since the power, KVM, network cables won't take up much depth? My most important equipment are all < 60cm depth (4U chassis) and should comfortably fit within the 800mm cabinet. The rest of the equipment are very old 1U servers that range from 65-72cm depth. I might still want to make further use of them, or I might discard them since they are so old. Even if the 72cm servers cannot be powered on in an 800mm rack, I should be able to use them as 1U shelves. But, what server depth can I expect to be able to operate? Or am I forced to upgrade to 1000mm depth racks in order to use any servers deeper than 60cm? With reference to best practices for HP racks, some other specs and installation considerations: There aren't any minimum recommendations for clearance on the sides of the rack. It is recommended to leave 48" front clearance. The 48" front clearance is based on 32" chassis depth, 13" to extend the rack rails and mate the inner/outer rails, and 3" for movement. If I don't use such rails (eg, use shelves instead), it should be sufficient to leave front clearance of chassis depth + 3". It is recommended to leave 30" rear clearance "to provide space for servicing the rack". I'm planning to back the rack into a corner of the room, and wheel it slightly out when I need to access the rear. If the wheeling plan is ok, I still need to know how much rear clearance is required for air circulation and ventilation purposes. Castor wheels and stabilising feet. Since I'm backing the rack into a corner of the room, I'll only be able to set the stabilising feet on the front corners. Thoughts on safety? The rack that I'm considering has front glass doors with side ventilation slits and fully perforated rear doors. I'm hoping this will be a good balance between temperature and noise (only ventilation slits facing out the front, while the rear is facing the walls). Or is the sound of high-rpm fans going to escape through the front slits anyway and destroy my sanity?

  • Open-source and client-side IRC-Client

    - by user125197
    I'm administrating a homepage with an IRC-Webclient. At the moment, it uses a Java-client, modified to be SSL-compatible and compatible with whatever design I want to use. The usual PJIRC thing, with users wishes and concerns implemented (I'll give you SSL-PJIRC if you want - no problem. The login-script will be improved for IE6-support this weekend, means write the object tag if an old IE is found, that's it. Rest runs perfectly well). But still, the better user experience would be a client that only requires the user to enable JavaScript. So, before I go into rewriting and customizing a complete Java-IRC-solution, I'd like to ask some other people - after researching for half a year of time. The requirements are: a) Free hosting, no cgi-bin is acceptable. A lot of hosters also have CGI supported, but it doesn't allow IRC-access. So, seems you are limited to x10-hosting for CGI:IRC. b) Solution must be open source (not free as in free beer, but free as in free speech - I want to be able to read every line of the code). c) Hosting cannot be limited to Windows-hosting. Free operation systems (anything with Linux, BSD, whatever - I think you get what I mean) must be possible. d) No server-side technology. I'm limited to everything that runs client-side only. (Well, a Java-Applet does...). d) Solution must support SSL. e) The side must be able to move. Means, you register to a new free hoster, load your things up via FileZilla and the thing simply runs. No server-concerning implementations needed. f) Old browsers must be supported. From all my research, there are two ways a) Java-Applet b) Use HTML5-Websockets (it is impossible to use the JavaScript-library I found, as it depends on ActiveX - means, Windows hosting). b) means "you are going to enter very unstable content". I worked with HTML5 for month, and, well ... Though, HTML5 also is not suitable for older browsers (old browser support is an absolutely necessary requirement). PHP by the way is a server side solution ... so no line of PHP. My idea now was a Java Applet, and a fallback which again is embedded and proprietary, but only requieres JavaScript (wsirc or Mibbit are great here, whilst I prefer wsirc ... and zooming fonts that are plainly to small, but worse, cannot read the code). So my question is - with free hosting, not installation on server, plain upload - do you see and open source, complelety client-side, ssl-compatible way to use or write a client? This wouldn't be my first programming project, I'm not afraid of the code. If there was a way and I had to write it, even from scratch, I'd do. From all I know, there sadly is none. But maybe some experienced admin has an idea? Best Wishes, yetanotheruser Sry my English isn't perfect. It's enough for programming at least.

  • 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.

  • Installing .NET application on IIS 7.5 issues

    - by Juw
    Really need some help here. I am at a loss. I am trying to install a webservice that some other guy wrote in .NET. I have some basic IIS understanding. The webservice works just fine on my dev computer. But now i try to move the webservice to a production server and bad things happens. The webservice has been located in C:\inetpub\wwwroot\ dir on the dev server. But on this production server it is to be located in D:\services\ I have managed to install an application on the production server and everything seems fine and dandy. But when i "Test Settings" in the initial setup i get "Invalid application path" error. But i can just close it down and still install it. But when i try to access the webservice with: http://myserver.com/webservice/GetData nothing happens. Just a blank page and when i check the response headers...500 error. I don´t know what is going on here or where the problem is. I post the config file here so someone hopefully might notice something odd. Thanx in advance! EDIT: The config file is from my dev server. I just copied it to my production server...but that obviously didn´t work :-) UPDATE: I noticed that my dev server run in an Application pool with Net 4 and in "classic" "mode". On the production server it was in NET 4 but in "integrated" mode. So i changed it to "classic". I still get a blank page. But checking the log will output this: 2012-10-03 14:57:00 ip removed GET /boo/GetData - 80 - ip removed Mozilla/5.0+(Windows+NT+6.1;+WOW64;+rv:15.0)+Gecko/20100101+Firefox/15.0.1 404 2 1260 203 <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.web> <identity impersonate="true" /> <!-- Impersonate NT AUTHORITY/IUSR --> <compilation targetFramework="4.0"> <assemblies> <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b7735c561131e089" /> </assemblies> </compilation> <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID" /> </system.web> <system.webServer> <modules runAllManagedModulesForAllRequests="true" /> <httpErrors existingResponse="PassThrough" /> <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> </customHeaders> </httpProtocol> <directoryBrowse enabled="false" /> </system.webServer> <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> <standardEndpoints> <webHttpEndpoint> <!-- Configure the WCF REST service base address via the global.asax.cs file and the default endpoint via the attributes on the <standardEndpoint> element below --> <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true" /> </webHttpEndpoint> </standardEndpoints> </system.serviceModel> <connectionStrings> <add name="Entities" connectionString="metadata=res://*/DataModel.csdl|res://*/DataModel.ssdl|res://*/DataModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=someip;initial catalog=db_90;User ID=user1;Password=access2;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" /> </connectionStrings> </configuration>

  • Connecting PC to TV via HDMI/DVI: Windows XP doesn't allow the appropriate screen resolution

    - by Jørgen
    I have a computer that is connected to the living room TV (a Panasonic) via HDMI. There is no other monitor connected. My problem is that the computer, which is running Windows XP, does not allow me to set the proper resolution for the TV. Both the graphics adapter and the TV should support the 1280x720 resolution, but it cannot be selected - the only available options are 1280x600 and 800x600, both in the "native" Windows dialog box and the custom Intel graphics options dialog box. Do anyone have a suggestion for a solution for this? Things I've thought of: Setting the resolution directly in the registry (where?) Installing some "custom" monitor driver (the TV manufacturer does not appear to provide any, currently the "generic" one is used) Details on the setup: Connection: DVI output on the computer via a passive DVI-HDMI adapter to the HDMI input on the TV, audio is run on a separate link, the TV is able to combine video and audio without any problem, the problem is there regardless of whether or not the audio is connected. The connection is several meters long through some walls, for this reason using a VGA cable instead is not an option. Note that the report explicitly says that the TV supports 1280x720. Still, I am not allowed to select it in Graphics Options, only 1280x600 and 800x600 is available. For 800x600, there's a lot of black around the edges; for 1280x600, the screen is "zoomed" so the edges of the monitor image (like the taskbar) is not visible. Other: The computer is running Windows XP. More recent versions of Windows are not an option (I have no licence). Linux is probably not an option (some of the video streaming sites I plan to use do not support it, I think) I wrote the rest of the details below. Thanks for any help!! TV: Panasonic TX-L32X10Y, European version; a 720p 32" quite "regular" LCD TV. Allowed resolutions according to manual: Signal name: 640x480 @60HZ Horizontal frequency: 31.47 kHz Vertical frequency: 60Hz Signal name: 750/720) /60p Horizontal frequency: 45.00 kHz Vertical frequency: 60Hz Signal name: 1,125 (1,080) / 60p Horizontal frequency: 67.50 kHz Vertical frequency: 60Hz (this is exactly how the manual presents it. PC via D-SUB (VGA cable) and "regular" HDMI have more alternatives.) Messing with the "zoom" settings on the TV does not affect the available resolution options on the computer. Computer: The following is a printout from one of the graphics adapter option pages. I think it covers most of it. The computer is a Dell. INTEL(R) EXTREME GRAPHICS 2 REPORT Report Date: 04/17/2011 Report Time[hr:mm:ss]: 20:18:02 Driver Version: 6.14.10.4396 Operating System: Windows XP* Professional, Service Pack 3 (5.1.2600) Default Language: English DirectX* Version: 9.0 Physical Memory: 1021 MB Minimum Graphics Memory: 1 MB Maximum Graphics Memory: 96 MB Graphics Memory in Use: 6 MB Processor: x86 Processor Speed: 2593 MHZ Vendor ID: 8086 Device ID: 2572 Device Revision: 02 * Accelerator Information * Accelerator in Use: Intel(R) 82865G Graphics Controller Video BIOS: 2972 Current Graphics Mode: 1280 by 600 True Color (60 Hz) * Devices Connected to the Graphics Accelerator * Active Digital Displays: 1 * Digital Display * Monitor Name: Plug and Play Monitor Display Type: Digital Gamma Value: 2.20 DDC2 Protocol: Supported Maximum Image Size: Horizontal: Not Available Vertical: Not Available Monitor Supported Modes: 1280 by 720 (50 Hz) 1280 by 720 (60 Hz) Display Power Management Support: Standby Mode: Not Supported Suspend Mode: Not Supported Active Off Mode: Not Supported (disclaimer: this question was also asked at the Wikipedia Reference Desk some time ago and might show up in a Google search.

  • Android RelativeLayout fill_parent unexpected behavior in a ListView with varying row heights

    - by Jameel Al-Aziz
    I'm currently working on a small update to a project and I'm having an issue with Relative_Layout and fill_parent in a list view. I'm trying to insert a divider between two sections in each row, much like the divider in the call log of the default dialer. I checked out the Android source code to see how they did it, but I encountered a problem when replicating their solution. To start, here is my row item layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:padding="10dip" android:layout_height="fill_parent" android:maxHeight="64dip" android:minHeight="?android:attr/listPreferredItemHeight"> <ImageView android:id="@+id/infoimage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:clickable="true" android:src="@drawable/info_icon_big" android:layout_alignParentRight="true" android:layout_centerVertical="true"/> <View android:id="@+id/divider" android:background="@drawable/divider_vertical_dark" android:layout_marginLeft="11dip" android:layout_toLeftOf="@+id/infoimage" android:layout_width="1px" android:layout_height="fill_parent" android:layout_marginTop="5dip" android:layout_marginBottom="5dip" android:layout_marginRight="4dip"/> <TextView android:id="@+id/TextView01" android:textAppearance="?android:attr/textAppearanceLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_toRightOf="@+id/ImageView01" android:layout_toLeftOf="@+id/divider" android:gravity="left|center_vertical" android:layout_marginLeft="4dip" android:layout_marginRight="4dip"/> <ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:background="@drawable/bborder" android:layout_centerVertical="true"/> </RelativeLayout> The issue I'm facing is that each row has a thumbnail of varying height (ImageView01). If I set the RelativeLayout's layout_height property to fill_parent, the divider does not scale vertically to fill the row (it just remains a 1px dot). If I set layout_height to "?android:attr/listPreferredItemHeight", the divider fills the row, but the thumbnails shrink. I've done some debugging in the getView() method of the adapter, and it seems that the divider's height is not being set properly once the row has it's proper height. Here is a portion of the getView() method: public View getView(int position, View view, ViewGroup parent) { if (view == null) { view = inflater.inflate(R.layout.tag_list_item, parent, false); } The rest of the method simply sets the appropriate text and images for the row. Also, I create the inflater object in the adapter's constructor with: inflater = LayoutInflater.from(context); Am I missing something essential? Or does fill_parent just not work with dynamic heights?

  • jqGrid multi-checkbox custom edittype solution

    - by gsiler
    For those of you trying to understand jqGrid custom edit types ... I created a multi-checkbox form element, and thought I'd share. This was built using version 3.6.4. If anyone has a more efficient solution, please pass it on. Within the colModel, the appropriate edit fields look like this: edittype:'custom' editoptions:{ custom_element:MultiCheckElem, custom_value:MultiCheckVal, list:'Check1,Check2,Check3,Check4' } Here are the javascript functions (BTW, It also works – with some modifications – when the list of checkboxes is in a DIV block): //———————————————————— // Description: // MultiCheckElem is the "custom_element" function that builds the custom multiple check box input // element. From what I have gathered, jqGrid calls this the first time the form is launched. After // that, only the "custom_value" function is called. // // The full list of checkboxes is in the jqGrid "editoptions" section "list" tag (in the options // parameter). //———————————————————— function MultiCheckElem( value, options ) { //———- // for each checkbox in the list // build the input element // set the initial "checked" status // endfor //———- var ctl = ''; var ckboxAry = options.list.split(','); for ( var i in ckboxAry ) { var item = ckboxAry[i]; ctl += '<input type="checkbox" '; if ( value.indexOf(item + '|') != -1 ) ctl += 'checked="checked" '; ctl += 'value="' + item + '"> ' + item + '</input><br />&nbsp;'; } ctl = ctl.replace( /<br />&nbsp;$/, '' ); return ctl; } //———————————————————— // Description: // MultiCheckVal is the "custom_value" function for the custom multiple check box input element. It // appears that jqGrid invokes this function the first time the form is submitted and, the rest of // the time, when the form is launched (action = set) and when it is submitted (action = 'get'). //———————————————————— function MultiCheckVal(elem, action, val) { var items = ''; if (action == 'get') // the form has been submitted { //———- // for each input element // if it's checked, add it to the list of items // endfor //———- for (var i in elem) { if (elem[i].tagName == 'INPUT' && elem[i].checked ) items += elem[i].value + ','; } // items contains a comma delimited list that is returned as the result of the element items = items.replace(/,$/, ''); } else // the form is launched { //———- // for each input element // based on the input value, set the checked status // endfor //———- for (var i in elem) { if (elem[i].tagName == 'INPUT') { if (val.indexOf(elem[i].value + '|') == -1) elem[i].checked = false; else elem[i].checked = true; } } // endfor } return items; }
