• video and file caching with squid lusca?

  - by moon

  hello all i have configured squid lusca on ubuntu 11.04 version and also configured the video caching but the problem is the squid cannot configure the video more than 2 min long and the file of size upto 5.xx mbs only. here is my config please guide me how can i cache the long videos and files with squid: > # PORT and Transparent Option http_port 8080 transparent server_http11 on icp_port 0 > > # Cache Directory , modify it according to your system. > # but first create directory in root by mkdir /cache1 > # and then issue this command chown proxy:proxy /cache1 > # [for ubuntu user is proxy, in Fedora user is SQUID] > # I have set 500 MB for caching reserved just for caching , > # adjust it according to your need. > # My recommendation is to have one cache_dir per drive. zzz > > #store_dir_select_algorithm round-robin cache_dir aufs /cache1 500 16 256 cache_replacement_policy heap LFUDA memory_replacement_policy heap > LFUDA > > # If you want to enable DATE time n SQUID Logs,use following emulate_httpd_log on logformat squid %tl %6tr %>a %Ss/%03Hs %<st %rm > %ru %un %Sh/%<A %mt log_fqdn off > > # How much days to keep users access web logs > # You need to rotate your log files with a cron job.

But when I run it, I found memeory can not read error. I debug and step into and found the error happens in stl function template<typename _RandomAccessIterator, typename _Distance, typename _Tp, typename _Compare> void __adjust_heap(_RandomAccessIterator __first, _Distance __holeIndex, _Distance __len, _Tp __value, _Compare __comp) { const _Distance __topIndex = __holeIndex; _Distance __secondChild = __holeIndex; while (__secondChild < (__len - 1) / 2) { __secondChild = 2 * (__secondChild + 1); if (__comp(*(__first + __secondChild), *(__first + (__secondChild - 1)))) __secondChild--; *(__first + __holeIndex) = _GLIBCXX_MOVE(*(__first + __secondChild)); ////// stop here __holeIndex = __secondChild; } Of course, there must be something wrong with the customized operators of iterator. Does anyone know the possible reason? Thank you.

• Perl cron job stays running

  - by Dylan

  I'm currently using a cron job to have a Perl script that tells my Arduino to cycle my aquaponics system and all is well, except the Perl script doesn't die as intended. Here is my cron job: */15 * * * * /home/dburke/scripts/hal/bin/main.pl cycle And below is my Perl script: #!/usr/bin/perl -w # Sample Perl script to transmit number # to Arduino then listen for the Arduino # to echo it back use strict; use Device::SerialPort; use Switch; use Time::HiRes qw ( alarm ); $|++; # Set up the serial port # 19200, 81N on the USB ftdi driver my $device = '/dev/arduino0'; # Tomoc has to use a different tty for testing #$device = '/dev/ttyS0'; my $port = new Device::SerialPort ($device) or die('Unable to open connection to device');; $port->databits(8); $port->baudrate(19200); $port->parity("none"); $port->stopbits(1); my $lastChoice = ' '; my $pid = fork(); my $signalOut; my $args = shift(@ARGV); # Parent must wait for child to exit before exiting itself on CTRL+C $SIG{'INT'} = sub { waitpid($pid,0) if $pid != 0; exit(0); }; # What child process should do if($pid == 0) { # Poll to see if any data is coming in print "\nListening...\n\n"; while (1) { my $incmsg = $port->lookfor(9); # If we get data, then print it if ($incmsg) { print "\nFrom arduino: " . $incmsg . "\n\n"; } } } # What parent process should do else { if ($args eq "cycle") { my $stop = 0; sleep(1); $SIG{ALRM} = sub { print "Expecting plant bed to be full; please check.\n"; $signalOut = $port->write('2'); # Signal to set pin 3 low print "Sent cmd: 2\n"; $stop = 1; }; $signalOut = $port->write('1'); # Signal to arduino to set pin 3 High print "Sent cmd: 1\n"; print "Waiting for plant bed to fill...\n"; alarm (420); while ($stop == 0) { sleep(2); } die "Done."; } else { sleep(1); my $choice = ' '; print "Please pick an option you'd like to use:\n"; while(1) { print " [1] Cycle [2] Relay OFF [3] Relay ON [4] Config [$lastChoice]: "; chomp($choice = <STDIN>); switch ($choice) { case /1/ { $SIG{ALRM} = sub { print "Expecting plant bed to be full; please check.\n"; $signalOut = $port->write('2'); # Signal to set pin 3 low print "Sent cmd: 2\n"; }; $signalOut = $port->write('1'); # Signal to arduino to set pin 3 High print "Sent cmd: 1\n"; print "Waiting for plant bed to fill...\n"; alarm (420); $lastChoice = $choice; } case /2/ { $signalOut = $port->write('2'); # Signal to set pin 3 low print "Sent cmd: 2"; $lastChoice = $choice; } case /3/ { $signalOut = $port->write('1'); # Signal to arduino to set pin 3 High print "Sent cmd: 1"; $lastChoice = $choice; } case /4/ { print "There is no configuration available yet. Please stab the developer."; } else { print "Please select a valid option.\n\n"; } } } } } Why wouldn't it die from the statement die "Done.";? It runs fine from the command line and also interprets the 'cycle' argument fine. When it runs in cron it runs fine, however, the process never dies and while each process doesn't continue to cycle the system it does seem to be looping in some way due to the fact that it ups my system load very quickly.

• Why do I see "Operation was denied because the current credentials do not have the appropriate privileges" when trying to chsh?

  - by alecmce

  I'm setting up a new dev Macbook Pro, and trying to replace bash with zsh. I installed zsh and can run it to change shell in a session. When I use sudo chsh -s /bin/zsh username I get the error message: chsh: Operation was denied because the current credentials do not have the appropriate privileges. Operation was denied because the current credentials do not have the appropriate privileges. AFAIK I have admin privileges on the machine. What could be causing this?

• Gacutil.exe on Windows Server 2008 Standard SP2

  - by IrishChieftain

  I'm trying to deploy a Web Part Feature as part of solution. Solution being add to the store and feature being added successfully. Full trust enabled in Web.Config for bin deployment of the .DLL but Web Part not working when page viewed by a non-admin user... So, decided to deploy to GAC but discovered that gacutil.exe is not included with the OS? The only place I can find it is in the Windows SDK with a download size of over 22GB! I know I can choose to download only certain components, but which ones should I select and are there any dependencies? Better yet, is there an easier way to get a copy of the gacutil.exe tool?

• Enabling SFTP Access within PLESK

  - by spelley

  Hello everyone, I have a client who wants to ensure his upload is secure, so we are trying to enable SFTP for him on our Linux PLESK server. I have enabled SSH access to bin/bash for FTP accounts, and created a new user. When I attempt to SFTP using either the IP address or the domain name, this is the error FileZilla is giving me: Error: Authentication failed. Error: Critical error Error: Could not connect to server Here is some basic information regarding the server: Operating system Linux 2.6.24.5-20080421a Plesk Control Panel version psa v8.6.0_build86080930.03 os_CentOS 5 I had read in some places that I should reboot the SSH Service in Server - Services, however, there is no SSH Service within the list. I'm not really a server guy so it's quite possible I'm missing something obvious. Thanks for any help that you guys can provide!

• How would you apply a BIOS update for a Dell M610 blade with VMware ESXi installed?

  - by Guamaniac

  Hello, all. We've got a Dell M610 blade with VMware ESXi 4 installed and we need to update it's BIOS to the latest version. Unfortunately, Dell only makes available a Windows (.exe) and Linux (.bin) versions of the BIOS update program (as well as a bootable DOS floppy version that is too big to fit on a 1.44MB floppy!). We've tried using various "LiveCD" versions of linux distributions but keep running into errors. Anyone out there with experience with Dell blades who could give us a hint or two to get this working? Thanks a lot, in advance. Joe

• How to configure Apache so all requests go to single CGI file

  - by fastmonkeywheels

  I'm porting a CGI application from an embedded web server to run under Apache. In the effort of changing the least amount required I'm trying to figure out how to configure Apache so any requests coming in go to my CGI program, which then will use the QueryString environmental variable to determine which file needs to be created. I have Apache working now to where it will process my CGI file if it's requested directly i.e. localhost/cgi-bin/cgi_test.out but I need to figure out how to get my application to be called whenever any file is requested: localhost/ - call my application with QueryString set to "" or "/" localhost/thisFile - call my application with QueryString set to "/thisFile" etc. I have been doing all of my configuration testing under /etc/apache2/sites-available/mysite, which has been enabled and the default disabled. Thanks for any help. I've tried the recommendation from here: http://serverfault.com/questions/56082/configure-apache-to-handle-all-requests-via-single-index-php but I keep getting circular redirects.

• MySQL replication Slave_IO_Running: No

  - by Christy

  Hi all, I have two servers that I am trying to get replication of one database between. I found a setup guide on sourceforge that I followed and I have tried various other settings since then, but no matter what I do, when I start the slave, the 'Slave_IO_Running' setting is always No.... I have no idea why or what to look at, any suggestions are appreciated. The slave setup was: CHANGE MASTER TO MASTER_HOST='myserver.mydomain.net', MASTER_USER='slave_user', 'MASTER_PASSWORD='mypassword', 'MASTER_LOG_FILE='mysql-bin.000011', MASTER_LOG_POS=1368363 (last data from today, trying to do setup again. I deleted and recreated the database on the slave from a new dump and tried to redo the setup.) I have slave_user setup for %, localhost, and the specific IP of the slave computer but nothing seems to be working... Thanks in advance for any advice or suggestions

• Winbind group lookup painfully slow

  - by Marty

  I am running winbind on an RHEL 6 system. Everything works fine except group lookups, so many commands (including sudo) are painfully slow. I did an strace which shows that winbind looks up every group and every user within each group for the current user. Some of these groups have 20000+ users so a simple sudo can take 60 seconds to complete. I really only care about speeding up the sudo command. Ideal solutions would make it so either: groups with more than X number of users will not be looked up, or sudo bypasses group lookups altogether. Here is my current "smb.conf" for winbind: workgroup = EXAMPLE password server = AD1.EXAMPLE.ORG realm = EXAMPLE.ORG security = ads idmap uid = 10000-19999 idmap gid = 10000-19999 idmap config EXAMPLE:backend = rid idmap config EXAMPLE:range = 10000000-19999999 winbind enum users = no winbind enum groups = no winbind separator = + template homedir = /home/%U template shell = /bin/bash winbind use default domain = yes winbind offline logon = false

• Permission denied when using mv in Windows 7 Cygwin

  - by Michael Butler

  I have Cygwin installed on Windows 7 in a windows domain sign-on environment. I can run most typical commands without issue, but I cannot for the life of me use the "mv" command to move or rename files, regardless of the file or directory. I can copy and create files without issue. +-[12:27:57]-[mbutl2@MYHOSTNAME] +--> tmp $ >> pwd /tmp +-[12:27:58]-[mbutl2@MYHOSTNAME] +--> tmp $ >> touch test.txt +-[12:28:02]-[mbutl2@MYHOSTNAME] +--> tmp $ >> mv test.txt hello -bash: /usr/bin/mv: Permission denied I have already tried running Cygwin terminal as Administrator and the problem is the same. I'm open to workarounds, such as trying another exe for moving files and redirecting the mv command to it. Moving files works in the Windows Command Prompt.

• Rsync from godaddy to OS X

  - by Ola

  I would like to use rsync to backup my website to my local computer (OS X). I started of with this guide and got pretty far. I use the following rsync-line: rsync -PzrlptgD --del --delete-excluded -r --rsync-path=~/bin/rsync user@server:~/ /local/backup/folder/ I wanted to use the -a option (same as rlptgoD) but it crashes as soon as I use the -o flag. receiving file list ... rsync: connection unexpectedly closed (8 bytes received so far) [receiver] rsync error: unexplained error (code 255) at /SourceCache/rsync/rsync-42/rsync/io.c(452) [receiver=2.6.9] If I skip the --owner flag it copies the files but I'm not really sure what difference it makes (I've tried to read up on it but found nothing) Should I just skip using the --owner flag? Or have I done any other mistake? Thanks in advance //OL

  Running RSH commands on a Windows box against a Linux box works only for the administrator user. Is there a file somewhere that has a list of users that can run commands remotely? More Info The server configuration is automated by VMware's product... There's no /etc/hosts.equiv file setup but there is a /root/.rhosts file with an entry of [IP ADDRESS] +. The SUA client C:\Windows\SUA\bin\rsh can login when run as the local administrator account but no other user can login. The error is: rcmd: unknown user: [username].
