• Cant access folder on server- Permission denied

  - by Michal Korzeniowski

  I am running a vps with ubuntu 11.04. After a clean Modx install I've tried to access http://www.encepence.pl/manager and I've got a permission denied by my server. the thing is that I can easily access any other folder under that domain and modify this folder(manager) content via ftp. I’ve tried modifying virtual host with that <Directory /var/www/blackflow/data/www/encepence.pl/manager/> Options Indexes FollowSymLinks ExecCGI AllowOverride All Order allow,deny Allow from all </Directory> But it didn't work. <Directory /var/www/blackflow/data/www/encepence.pl> Options -ExecCGI -Includes php_admin_value open_basedir "/var/www/blackflow/data:." php_admin_flag engine on </Directory> <VirtualHost 192.166.219.34:80 > ServerName encepence.pl CustomLog /var/www/httpd-logs/encepence.pl.access.log combined DocumentRoot /var/www/blackflow/data/www/encepence.pl ErrorLog /var/www/httpd-logs/encepence.pl.error.log ServerAdmin [email protected] ServerAlias www.encepence.pl SuexecUserGroup blackflow blackflow AddType application/x-httpd-php .php .php3 .php4 .php5 .phtml AddType application/x-httpd-php-source .phps php_admin_value open_basedir "/var/www/blackflow/data:." php_admin_value sendmail_path "/usr/sbin/sendmail -t -i -f [email protected]" php_admin_value upload_tmp_dir "/var/www/blackflow/data/mod-tmp" php_admin_value session.save_path "/var/www/blackflow/data/mod-tmp" VirtualDocumentRoot /var/www/blackflow/data/www/%0 </VirtualHost> Any ideas on what might have gone wrong?

• Solr startup script problem

  - by Camran

  I have installed solr and it works finally... I have now problems setting it up to start automatically with a start command. I have followed a tutorial and created a file called solr in the /etc/init.d/solr dir... Here is that file: #!/bin/sh -e # SOLR auto-start # # description: auto-starts solr engine # processname: solr-production # pidfile: /var/run/solr-production.pid NAME="solr" PIDFILE="/var/run/solr-production.pid" LOG_FILE="/var/log/solr-production.log" SOLR_DIR="/etc/jetty" JAVA_OPTIONS="-Xmx1024m -DSTOP.PORT=8079 -DSTOP.KEY=stopkey -jar start.jar" JAVA="/usr/bin/java" start() { echo -n "Starting $NAME...

Also here is where I have solr installed: var/www/solr and here is the start.jar file located: var/www/start.jar Help me out if you know whats causing this. Thanks BTW: OS is ubuntu 9.10

• switchover in postgresql

  - by user1010280

  I am using Postgresql 9.0 with Streaming replication. So, during switchover I follow these steps:- Get the server timestamp on primary. Get the current log position on primary. Set Verify Log location Verify Transaction Received Location Shutdown DB on production. Synchronize the transaction logs from PR to DR. Trigger a failover on the DR Database by creating the trigger file specified in recovery.conf Verify DB Mode on DR Copy the control file from from DR to primary. copy the temporary stats file from DR to primary. copy the history file from DR to primary. Create recovery.conf file. Start Database in standby mode in primary. Verify DB mode on PR At step (6), I have to copy last wal generated on Primary to standby and sync both PR and standby. but this thing takes time to copy files because this remote. So that postgres will keep seraching for wal for long time and after that it stops the server. So I want to know is there any way so that I can ask postgres to stop seraching or locating WAL after shutdown??? because postgres tries to locate this wal every 5 seconds. Please reply as soon as possible..its urgent...

• Requests per second slower when using nginx for load balancing

  - by Ed Eliot

  I've set up nginx as a load balancer that reverse proxies requests to 2 Apache servers. I've benchmarked the setup with ab and am getting approx 35 requests per second with requests distributed between the 2 backend servers (not using ip_hash). What is confusing me is that if I query either of the backend servers directly via ab I get around 50 requests per second. I've experimented with a number of different values in ab the most common being 1000 requests with 100 concurrent connections. Any idea why traffic distributed across 2 servers would result in fewer requests per second than hitting either directly? Additional info: I've experimented with worker_processes values of between 1 and 8, worker_connections between 1024 and 8092 and have also tried keepalive 0 and 65. My main conf currently looks like this: user www-data; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; worker_rlimit_nofile 8192; events { worker_connections 2048; use epoll; } http { include /etc/nginx/mime.types; sendfile on; keepalive_timeout 0; tcp_nodelay on; gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } I've got one virtual host (in sites available) that redirects everything under / to 2 backends across a local network.

• Upstart can't determine my process' pid

  - by sirlark

  I'm writing an upstart script for a small service I've written for my colleagues. My upstart job can start the service, but when it does it only outputs queryqueue start/running; note the lack of a pid as given for other services. #/etc/init/queryqueue.conf description "Query Queue Daemon" author "---" start on started mysql stop on stopping mysql expect fork env DEFAULTFILE=/etc/default/queryqueue umask 007 kill timeout 30 pre-start script #if [ -f "$DEFAULTFILE" ]; then # . "$DEFAULTFILE" #fi [ ! -f /var/run/queryqueue.sock ] || rm -rf /var/run/queryqueue.sock #exec /usr/local/sbin/queryqueue -s /var/run/queryqueue.sock -d -l /tmp/upstart.log -p $PIDFILE -n $NUM_WORKERS $CLEANCACHE $FLUSHCACHE $CACHECONN end script script #Originally this stanza didn't exist at all if [ -f "$DEFAULTFILE" ]; then . "$DEFAULTFILE" fi exec /usr/local/sbin/queryqueue -s /var/run/queryqueue.sock -d -l /tmp/upstart.log -p $PIDFILE -n $NUM_WORKERS $CLEANCACHE $FLUSHCACHE $CACHECONN end script post-start script for i in `seq 1 5` ; do [ -S /var/run/queryqueue.sock ] && exit 0 sleep 1 done exit 1 end script The service in question is a python script, which when run without error, forks using the code below right after checking command line options and basic environmental sanity, so I tell upstart to expect fork. pid = os.fork() if pid != 0: sys.exit(0) The script is executable, and has a python shebang. I can send the TERM signal to the process manually, and it quits gracefully. But running stop queryqueue claims queryqueue stop/waiting but the process is still alive and well. Also, it's logs indicate it never received the kill signal. I'm guessing this is because upstart doesn't know which pid it has. I've also tried expect daemon and leaving the expect clause out entirely, but there's no change in behaviour. How can I get upstart to determine the pid of the exec'd process

• SendMail not working in CentOs 6.4

  - by Kane

  I am trying to send e-mails from my CentOS 6.4 but it does not work. My knowledge about servers is quite limited, so I hope someone can help me. Here is what I did: First i tried to send an email using the "mail" command, but it was not in the OS so I installed it. # yum install mailx After that, I tried sending an email using the "mail" command, but it did not send anything. I checked it on the internet and I realized I needed an e-mail server like sendmail, so I installed it. # yum install sendmail sendmail-cf sendmail-doc sendmail-devel After that, I configured it following some tutorials. First, sendmail.mc file. # vi /etc/mail/sendmail.mc Commented out the next line: BEFORE # DAEMON_OPTIONS('Port=smtp, Name=MTA') dnl AFTER # dnl DAEMON_OPTIONS('Port=smtp, Name=MTA') dnl Check that the next lines are correct: # FEATURE(`virtusertable', `hash -o /etc/mail/virtusertable.db')dnl # ... # FEATURE(use_cw_file)dnl # ... # FEATURE(`access_db', `hash -T<TMPF> -o /etc/mail/access.db')dnl Update sendmail.cf # m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf Open the port 25 adding the proper line in the iptables file # vi /etc/sysconfig/iptables # -A INPUT -m state --state NEW -m tcp --dport 25 -j ACCEPT restart iptables and sendmail # service iptables restart # service sendmail restart So i thought that would be ok, but when i tried: # mail '[email protected]' # Subject: test subject # test content #. I checked the mail log: # vi /var/log/maillog And that is what I found: Aug 14 17:36:24 dev-admin-test sendmail[20682]: r7D8RItS019578: to=<[email protected]>, ctladdr=<[email protected]> (0/0), delay=1+00:09:06, xdelay=00:00:00, mailer=esmtp, pri=2460500, relay=alt4.gmail- smtp-in.l.google.com., dsn=4.0.0, stat=Deferred: Connection timed out with alt4.gmail-smtp-in.l.google.com. I do not understand why there is a connection time out. Am I missing something? Can anyone help me, please? Thank you.

• Courier-imap login problem after upgrading / enabling verbose logging

  - by halka

  I've updated my mail server last night, from Debian etch to lenny. So far I've encountered a problem with my postfix installation, mainly that I managed to broke the IMAP access somehow. When trying to connect to the IMAP server with Thunderbird, all I get in mail.log is: Feb 12 11:57:16 mail imapd-ssl: Connection, ip=[::ffff:10.100.200.65] Feb 12 11:57:16 mail imapd-ssl: LOGIN: ip=[::ffff:10.100.200.65], command=AUTHENTICATE Feb 12 11:57:16 mail authdaemond: received auth request, service=imap, authtype=login Feb 12 11:57:16 mail authdaemond: authmysql: trying this module Feb 12 11:57:16 mail authdaemond: SQL query: SELECT username, password, "", '105', '105', '/var/virtual', maildir, "", name, "" FROM mailbox WHERE username = '[email protected]' AND (active=1) Feb 12 11:57:16 mail authdaemond: password matches successfully Feb 12 11:57:16 mail authdaemond: authmysql: sysusername=<null>, sysuserid=105, sysgroupid=105, homedir=/var/virtual, [email protected], fullname=<null>, maildir=xoxo.sk/[email protected]/, quota=<null>, options=<null> Feb 12 11:57:16 mail authdaemond: Authenticated: sysusername=<null>, sysuserid=105, sysgroupid=105, homedir=/var/virtual, [email protected], fullname=<null>, maildir=xoxo.sk/[email protected]/, quota=<null>, options=<null> ...and then Thunderbird proceeds to complain that it cant' login / lost connection. Thunderbird is definitely not configured to connect through SSL/TLS. POP3 (also provided by Courier) is working fine. I've been mainly looking for a way to make the courier-imap logging more verbose, like can be seen for example here. Edit: Sorry about the mess, I've found that I've been funneling the log through grep imap, which naturally didn't display entries for authdaemond. The verbose logging configuration entry is found in /etc/courier/imapd under DEBUG_LOGIN=1 (set to 1 to enable verbose logging, set to 2 to enable dumping plaintext passwords to logfile. Careful.)

• Restrict SSH user to connection from one machine

  - by Jonathan

  During set-up of a home server (running Kubuntu 10.04), I created an admin user for performing administrative tasks that may require an unmounted home. This user has a home directory on the root partition of the box. The machine has an internet-facing SSH server, and I have restricted the set of users that can connect via SSH, but I would like to restrict it further by making admin only accessible from my laptop (or perhaps only from the local 192.168.1.0/24 range). I currently have only an AllowGroups ssh-users with myself and admin as members of the ssh-users group. What I want is something that works like you may expect this setup to work (but it doesn't): $ groups jonathan ... ssh-users $ groups admin ... ssh-restricted-users $ cat /etc/ssh/sshd_config ... AllowGroups ssh-users [email protected].* ... Is there a way to do this? I have also tried this, but it did not work (admin could still log in remotely): AllowUsers [email protected].* * AllowGroups ssh-users with admin a member of ssh-users. I would also be fine with only allowing admin to log in with a key, and disallowing password logins, but I could find no general setting for sshd; there is a setting that requires root logins to use a key, but not for general users.

• IIS / Virtual Directory authentication.

  - by Chris L

  I have an IIS(v6)/Windows 2003/.Net 3.5(app code, libraries etc.) server hosting a website at www.mywebsite.com mapped to E:\Inetpub\wwwroot\mywebsite, we also have a virtual directory (VirtDir) mapped out to E:\Inetpub\wwwroot\mywebsite\files (although in theory this could be in a different directory or a separate machine) where we store a customer's files(a bunch of .pdf & .xls). Currently to access a file you can enter into the url something like: www.mywebsite.com/VirtDir/Customer/myFile.pdf and get access to the file. The problem is the user doesn't have to log into www.mywebsite.com to get access to the file, we would prefer them to log in first. We would like the user to login via the mywebsite and if valid, let them download files from the virtual directory. The www.mywebsite.com and VirtDir are separate sites on the same farm. Allow Anon Access, and Integrated Windows Authentication both enabled. I'm more of a developer and less of a Sys Admin, but hopefully I'm in the right spot, any help would be appreciated.

• On Windows 2008 R2, how do I back up DHCP if the DHCP .mdb database is always busy?

  - by johnny

  I get this from my backup software. C:\WINDOWS\system32\dhcp\dhcp.mdb : The process cannot access the file because it is being used by another process. C:\WINDOWS\system32\dhcp\j50.log : The process cannot access the file because it is being used by another process. C:\WINDOWS\system32\dhcp\j50tmp.log : The process cannot access the file because it is being used by another process. C:\WINDOWS\system32\dhcp\tmp.edb : The process cannot access the file because it is being used by another process. My questions: Should I be doing a manual backup of DHCP via command line tools or maybe with MMC, Action, Backup before I run my backup? Is the %SystemRoot%\System32\DHCP\Backup directory always kept up to date? (which does get backed up by backup software) I'm answering my own question but the registry key is set up for 3c, 60 minutes, I believe. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCPServer\Parameters\BackupInterva This is not the included backup software for Windows. It is another product, but I have seen this with every backup software I've ever used.

• problems installing mysql and phpmyadmin to localhost

  - by Joel

  Hi guys, I know there have been many similar questions, but as far as I can tell, most of the other people have gotten further than I have... I'm trying to get a WAMP setup happening. I've got PHP and Apache running and talking to each other. PHP is in c:\PHP Apache is in it's default program files folder. mySQL is in it's default install location. I have localhost setup at D:\public_html\ I'm able to navigate to localhost and see html and php files. But I have a simple mySQL test file: <?php // hostname or ip of server (for local testing, localhost should work) $dbServer='localhost'; // username and password to log onto db server $dbUser='root'; $dbPass=''; // name of database $dbName='test'; $link = mysql_connect("$dbServer", "$dbUser", "$dbPass") or die("Could not connect"); print "Connected successfully<br>"; mysql_select_db("$dbName") or die("Could not select database"); print "Database selected successfully<br>"; // close connection mysql_close($link); ?> When I try and open this, I get "could not connect" Now, I haven't even created a database yet, because I can't log into mySQL with phpmyadmin-so I think I've done something wrong in my mySQL install because they aren't talking to each other. I guess my main question is how do I first create a database in mySQL to be sure I have even installed it correctly?

• Windows Server 2008 can't start postgresql-x64-9.0 service: could not create any TCP/IP sockets

  - by Rob

  After rebooting a Windows Server 2008 machine to apply system updates, we recently we began having some issues running PostgreSQL 9.0. When we noticed the problem, we reverted the Windows updates, but the issue persists: From services.msc, attempting to start the postgresql-x64-9.0 service fails. Half-way through starting the progress bar becomes very slow, and eventually responds with error 1053; "the service did not respond in a timely fashion." Interestingly enough, bringing up the task manager shows multiple instances of postgres.exe have been started, and looking at the log file shows: 2011-02-10 14:44:02 ESTLOG: database system is ready to accept connections I then tried killing the processes, and starting via the command-line (as the user postgres), but I receive a different error: C:/Program Files/PostgreSQL/9.0/bin/pg_ctl.exe start -N "postgresql-x64-9.0" -D "F:/SHARE/postgres" -w waiting for server to start............................................................... pg_ctl: could not start server ESTWARNING: could not create listen socket for "192.168.0.101" ESTFATAL: could not create any TCP/IP sockets The log file again indicates that the database is ready to accept connections. Also, using netstat indicates that no other processes are using port 5432; I can't think of any other obvious reason that opening the listen socket might fail. Any help would be greatly appreciated.

• Loads of memory in "standby" on Windows Server 2008 R2

  - by Jaap

  In our SharePoint farm, our Web Front End servers all have loads of memory in "standby" mode, meaning very little is available for our IIS worker process. We have 32 GB of RAM in each of the boxes, and standby memory will creep up to about 28 GB, whereas the IIS worker process only seems to be using about 2 GB. Also, we've seen the machine use the swap file extensively while this memory was in standby, so I am starting to think that this memory in standby mode is stopping IIS from using it, forcing it to swap to disk, causing more performance problems. I used SysInternals RamMap to indentify what is being kept in memory, and it was able to tell me that almost everything in standby memory is of type "Mapped File". When I sort the files listed under the file summary tab in RamMap by file size, the largest files (around a few hundred meg each) are IIS log files and SharePoint log files. I would like to understand which process is loading these files into standby memory and why they are not being released. When I do an iisreset, it does not release the memory. Any ideas? Thanks!

• Hardware freeze during disk activity

  - by Thomi

  I built myself a linux-based NAS. It has several drives of various sizes and ages in an LVM configuration, with 800GB or so of data. The data is served using a simple samba server. This was working flawlessly, but after physically moving it, it has developed a strange fault: Whenever I do something on the server to cause disk activity, the entire machine freezes hard. This has the effect of killing any open network connections to the box, and generally making it useless. If I leave the machine for a few minutes it seems to come right again, but obviously this isn't really a solution. There are no error or warning messages in syslog, or the kernel logs. If I power the machine on, and leave it, it runs for several days without locking up. After that time I stopped testing. It doesn't freeze instantly - obviously it doesn't freeze while booting, and I can normally log in via SSH and start poking around in a few log files for a couple of minutes before it dies. My question is: What diagnostic tests can I run to determine the casuse?

• sendmail on Snow Leopard

  - by Jay

  I'm trying to get sendmail working on my MacBook Pro (OS 10.6.4), so that I can send mail with PHP's mail() function. If you know how to do this without sendmail, I'd be interested in that also. The plan is to send mail through smtp.gmail.com using my gmail account, unless you have a better idea. I did this and that didn't work. In /etc/postfix/smtp_sasl_passwords I tried both:     smtp.yourisp.com username:password and     smtp.yourisp.com [email protected]:password The problem seems to be that google doesn't like me. I don't think my ISP is blocking it because Mail.app can send email through smtp.gmail.com just fine. $email is my gmail address. $ printf "Subject: TestMail" | sendmail -f $email $email $ tail /var/log/mail.log Oct 21 19:38:18 Jays-MacBook-Pro postfix/master[8741]: daemon started -- version 2.5.5, configuration /etc/postfix Oct 21 19:38:18 Jays-MacBook-Pro postfix/qmgr[8743]: CAACBFA905: from=<$email>, size=377, nrcpt=1 (queue active) Oct 21 19:38:18 Jays-MacBook-Pro postfix/pickup[8742]: C2A68FA93A: uid=501 from=<$email> Oct 21 19:38:18 Jays-MacBook-Pro postfix/cleanup[8744]: C2A68FA93A: message-id=<20101021233818.$mydomain> Oct 21 19:38:18 Jays-MacBook-Pro postfix/qmgr[8743]: C2A68FA93A: from=<$email>, size=377, nrcpt=1 (queue active) Oct 21 19:38:18 Jays-MacBook-Pro postfix/smtp[8746]: initializing the client-side TLS engine Oct 21 19:38:18 Jays-MacBook-Pro postfix/smtp[8748]: initializing the client-side TLS engine Oct 21 19:38:49 Jays-MacBook-Pro postfix/smtp[8746]: connect to smtp.gmail.com[74.125.157.109]:25: Operation timed out Oct 21 19:38:49 Jays-MacBook-Pro postfix/smtp[8748]: connect to smtp.gmail.com[74.125.157.109]:25: Operation timed out Oct 21 19:38:49 Jays-MacBook-Pro postfix/smtp[8746]: CAACBFA905: to=<$email>, relay=none, delay=1334, delays=1304/0.04/30/0, dsn=4.4.1, status=deferred (connect to smtp.gmail.com[74.125.157.109]:25: Operation timed out) Oct 21 19:38:49 Jays-MacBook-Pro postfix/smtp[8748]: C2A68FA93A: to=<$email>, relay=none, delay=30, delays=0.08/0.05/30/0, dsn=4.4.1, status=deferred (connect to smtp.gmail.com[74.125.157.109]:25: Operation timed out) $ I also tried setting myhostname, mydomain, and myorigin in /etc/postfix/main.cf to $ nslookup myip (as displayed by http://www.whatismyip.com/) And still no luck. Any ideas?

• Samba Does Not List Files In Shared Directory

  - by Sean M

  I am running Samba on a CentOS server, and I am experiencing a problem where it allows me to connect to the server and see a share, but shows the share as an empty directory. I find this behavior strange. Here is the stanza in my smb.conf for the given share: [seanm] path = /home/seanm writeable = yes valid users = seanm, root read only = No Here's what I see on the server side: [seanm@server ~]$ ls -l -rw-r--r-- 1 seanm seanm 40 Jan 4 13:45 pangram.txt And yet: [seanm@client ~]$ smbclient //server/seanm -U seanm -W WORKGROUP Enter seanm's password: Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.0.33-3.29.el5_5.1] smb: \> ls . D 0 Fri Jan 7 10:08:55 2011 .. D 0 Fri Jan 7 07:58:31 2011 58994 blocks of size 262144. 50356 blocks available This behavior is present on both a Windows client and a Linux client system. The behavior is present with the firewall on and with the firewall off, so it's not that. Neither /var/log/messages nor /var/log/secure have any complaints about Samba. I doubt that SELinux is a problem: just in case, here are the relevant settings. [root@server ~]# getsebool -a | grep samba samba_domain_controller --> off samba_enable_home_dirs --> on samba_export_all_ro --> off samba_export_all_rw --> off samba_share_fusefs --> off samba_share_nfs --> off use_samba_home_dirs --> on virt_use_samba --> off What am I doing wrong here, and what can I do to fix it?

• UACCEEventLog 301 Filling Event Logs

  - by rjt

  After pushing out clients for the MS Application Compatibility Toolkit on our domain via GPO, UACCEEventLog 301 occurs a few times per second in the event log. Several Thousand per hour. One test i need to do is logon with Administrator to see if these events go away while Admin, but of course that is not a fix. This is only part of the event log entry, but is the most readable and clearly indicates yet another problem with Antivirus software. But still no fix. Originally, i posted this In Words and Bytes, but then edited it to make it much easier to read. LocalMachine\Users do have Read Access to this key. For a test, i added "Domain Users" but there are many more events for other parts of the registry and for Administrators. <XML> <TYPE> UacceRegistryVirtualization </TYPE> <EXENAME>smcgui.exe</EXENAME> <EXEPATH>c:\program files\symantec\symantec endpoint protection </EXEPATH> <APINAME>RegOpenKeyA</APINAME> <REGKEYNAME> HKEY_LOCAL_MACHINE\SOFTWARE \Symantec\Symantec Endpoint Protection\AV\Storages \SymHeurProcessProtection\RealTimeScan\0 </REGKEYNAME> <RESTRICTEDBYACL>FALSE</RESTRICTEDBYACL> <DESIREDACCESS>MAXIMUM_ALLOWED</DESIREDACCESS> <REGVALUENAME></REGVALUENAME> <REGVALUETYPE>0x00000000</REGVALUETYPE> <REGVALUEDATA></REGVALUEDATA> <CURRENTGROUP>Users</CURRENTGROUP> </XML>

• Login error in phpMyAdmin, problem setting auth_type in config.inc.php

  - by sergiom

  I'm having a problem accessing phpMyAdmin. A few weeks ago I did succeed configuring it for auth_type = 'cookie', but I still receive an error stating that I should have to set blowfish_secret. That was strange because it was set. So I changed auth_type from cookie to http, but it didn't work. I changed it back to cookie, but it doesn't work anymore. this is the error. phpMyAdmin - Error Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly. this is my C:\wamp\apps\phpmyadmin3.2.0.1\config.inc.php <?php /* Servers configuration */ $i = 0; /* Server: localhost [1] */ $i++; $cfg['Servers'][$i]['verbose'] = 'localhost'; $cfg['Servers'][$i]['host'] = 'localhost'; $cfg['Servers'][$i]['port'] = ''; $cfg['Servers'][$i]['socket'] = ''; $cfg['Servers'][$i]['connect_type'] = 'tcp'; $cfg['Servers'][$i]['extension'] = 'mysqli'; $cfg['Servers'][$i]['auth_type'] = 'cookie'; $cfg['Servers'][$i]['user'] = ''; $cfg['Servers'][$i]['password'] = ''; $cfg['Servers'][$i]['AllowNoPassword'] = false; $cfg['Servers'][$i]['blowfish_secret'] = 'this is my passphrase'; /* End of servers configuration */ $cfg['DefaultLang'] = 'en-utf-8'; $cfg['ServerDefault'] = 1; $cfg['UploadDir'] = ''; $cfg['SaveDir'] = ''; ?> I changed the blowfish_secret, since I don't remember the old one, and I deleted the cookies in my browser and restartd all wamp services and the browser. After I enter username and password in the login page I get the error. I've tried searching into the log files, but I'm a newbie and I'm not sure I've searched the right ones. I'm using Wamp server 2.0 that has Apache Version : 2.2.11 PHP Version : 5.3.0 MySQL Version : 5.1.36 phpmyadmin : 3.2.0.1

• Intermittent Trouble Entering Hibernate on WinXP

  - by kquinn

  My personal desktop, running 32-bit Windows XP SP2 (with 4GB RAM, 2.75GB addressable, swap disabled, hiberfil.sys existing and contiguous on C:\; SP3 is not installed because SP2 has been working fine and I do not want to re-qualify with SP3 just for sheer perversity) typically gets hibernated at night. For a long time this worked great, but recently the machine has had trouble entering hibernation. Sometimes when I press my power button (configured to hibernate), the box will start the procedure for hibernating (i.e., go to the blue "Windows XP" background logo and display a message about entering hibernation), but before displaying the usual blue-on-black hibernation progress bar it will drop back to the desktop. No error messages appear, on screen or in the system log. The only record of unsuccessful hibernation attempts in the system log, which proudly proclaims that "The Windows Image Acquisition (WIA) service entered the running state." once per failed hibernation attempt. The problem is almost certainly resource related: if I then close one or more applications which are running, and repeat the exact same process, the machine will hibernate perfectly. There does not appear to be a reliable high-water mark for virtual or physical memory use, below which the machine is guaranteed to hibernate; it's different every time (though typically, below about 1.1–1.4 GB memory usage seems to be where hibernate succeeds most often). Memory may not even be the relevant resource; as far as I know, it could also be handles or sockets. This behavior is relatively recent: it has only started in the last few months; before then, I could hibernate reliably no matter what the current resource use of the system. This machine claims to have hotfix Q909095 installed, but since the symptoms of my problem match KB909095 rather well, I'm suspicious if this fix is actually working as intended. Any ideas on how to fix this or where to start debugging?

• Flash drive suddenly died. Why? Can I recover it?

  - by mg

  Hi, I have a flash drive that I used not too much but, after few month of inactivity, it died. I know that flash drives have a limited write cycles but I am sure that this is not the problem.
