• Computer wakes itself few seconds after hibernation

  - by Juan Zamudio

  Hi all, this is the situation, this is a Dell Optiplex 755, I recently upgraded it to Windows 7 64 bits, it had Windows XP SP3 previously, on XP I never had a problem hibernating the PC, now with Windows 7 64 every time I hibernate the PC it wakes it self after 5 or so seconds. Here are the steps I already tried: On Windows 7 I enabled the hibernation following this steps In the MoBo the sleep settings are on S3 In the Mobo I disable remote wake ups I have disabled the remote wake up in the NIC When I run the lastwake command I get unknown device or something like that I already disable the wake timers on Windows I have the latest drivers from Intel, but I just found out that in the device Manager I get a warning sign on the "Intel AMT SOL (COM3)" device saying that it failed and windows stopped the device, I reinstalled the Intel drivers but nothing changed. The only thing that I haven't touch is Intel ME in the MoBo but I don't if that could help and what settings are correct. Thanks for you help.

• How to detect when a user copies files from a server over the network?

  - by Mr. Graves

  I have a few virtual servers + desktops that are used for shared development with remote users, including some consultants. Each user has an account with access to most aspects of the server. I don't want to prevent people from being productive, or track passwords or read emails, but I do want to know when and what files they copy from the virtual server or what they upload from the server to a remote site, and what if any applications they install. This will help make sure my IP is protected, that no one is installing tools they shouldn't, and that things are licensed appropriately. What is the simplest way to do this? In order of importance I would say detecting file transfers off the machine to be most critical. Thanks

• Dell Latitude E4300 TouchPad - Odd Behavior

  - by Cade Roux

  I'm seeing some intermittent behavior on the touchpad. First it wasn't working at all. Then during restart, for a little while it seemed like the buttons attached to the joystick and external mouse were both swapped left/right. Then I went in to the dell touchpad control and disabled the touchpad and re-enabled it and nothing happened. Then a short while after disabling the joystick the touch pad started working. So I restarted to see if it would keep the settings and before login, the touchpad appeared to work, then after login it stopped working for a few minutes while login continued. Then after the login was almost completed it started to work again. It appeared to have retained the settings for the disabled joystick. It seems like perhaps there are conflicting mouse drivers trying to simultaneously or similar. This doesn't seem normal for the touchpad to be disabled for so long after login. What steps should I take to ensure the drivers are right?

• SCP command Clarification

  - by david.colais

  I'm using the scp commands to pull some files from the remote server and one variation of the command is not working. I have 2 files names one.xml and two.xml in a remote server and I'm pulling these two files into the current dir using the following command: scp [email protected]:/student/class/Intermediate/one.xml . scp [email protected]:/student/class/Intermediate/two.xml . The above command works fine but if I use wildcards to pull all the xml files in a single shot as shown below it returns scp: No match. scp [email protected]:/student/class/Intermediate/*.xml . Why is it working if I pull the files individually and not working if I try to pull using wildcards.

• Using old RAID configured disk after new disk has been used in the controller

  - by Narendra

  I have Dell Poweredge T100 server with Dell SAS 6 and two hard disk on RAID 1. Last week the server died including one RAID 1 hard disk. We sent the server for repair and the problem with PSU was fixed. But the repair guys also checked the RAID controller by configuring new RAID with their test hard disk. Now if I install one working RAID 1 disk and one new disk, will the RAID controller let me continue my old RAID 1 and resync the new disk and continue? What I fear is the RAID controller will want the test hard from repair guys. Thus I have to re configure RAID 1 forcing me to wipe the working disc. If so, I've to backup the working disc, reconfigure RAID 1 and reinstall? Or is there better way? Note: I'm using DELL SAS confiugratio utility to manage RAID. (Press CTRL+C after BIOS)

• Is there a way to correct wrongly typed password / abort the operation while on password prompt in the console in MINGW32?

  - by jakub.g

  I sometimes mistype a password when being asked for it, e.g. by Git when pushing to remote repository. The password is not displayed (even masked as asterisks) in the console. Is there a way either to correct the password, or to abort the operation? Backspace for editing and CtrlC for aborting do not seem to work. I want to save some time instead of waiting for the remote authentication to fail, or providing a bad password, then Enter, CtrlC. Edit: Unfortunately CtrlU doesn't work for me (MINGW32 @ Windows XP). Any other guesses?

• What permissions are needed to do an LDAP bind to an Active Directory Server

  - by DrStalker

  What permissions are needed to perform an LDAP bind to an active directory server? I have a central domain (call it MAIN) that has two-way trusts to domains in other forests (call then REMOTE and FARAWAY) Using MAIN\myaccount as the username and my password I can bind to REMOTE fine, but not to FARAWAY; I get an invalid credentials response 80090308: LdapErr: DSID-0C09030B, comment: AcceptSecurityContext error, data 525, v893 In all other ways the trusts seem to work fine. What permissions do I need to check to figure out why the bind is failing? My understanding is that anyone in AUTHENTICATED USERS should be able to bind to LDAP, but that only seems to hold true for some domaians and not others.

• Outlook Prompting for password from Exchange server in domain environment

  - by jherlitz

  We are running exchange 2007 in a domain environment. We have mostly outlook 2003 clients, but in process of upgrading to outlook 07 over the next couple of weeks. Some users (both 03 & 07) are constantly getting prompted to enter their credentials. The 07 client I was working on this morning states "needs password" in the bottom right corner. It is also speratic, as it will work fine most days but not some other days. The user I was working with this morning, has been working fine. Now it just started up today. I have been googling this, and have found lot's of information, but nothing that has helped yet. A lot of the information out there is for outlook users using a external email account. Being they already logged into the domain, these users should not be prompted for their credentials. Any advice out there?

• Slow LAN transfer from 3rd party computer

  - by Chris

  Hi Everyone, I've got an odd problem that I'm not really sure where to start the troubleshooting process. I have a 'server' with Windows Server 2008R2 (64-bit) installed and it has a couple of hard drives. If I Remote Desktop into the server and transfer files from one HD to the other, all it fine. If however, I use my workstation (Windows 7 64bit) and open up a shared resource on the server and transfer a file from one hard drive on the server to another HD on the server (not using Remote Desktop, just Windows explorer/Network places), the transfer crawls... It takes about 5mins to discover files/calculate the transfer and then starts transferring at speeds like 56KB/s - 200KB/s. Both machines have Marvel GigE network ports with a TrendNet 8-port green GigE switch. I've set Jumbo packets to 9K on both machines...

• What Are All the Variables Necessary to Create Blackbox Logs for Nginx?

  - by Alan Gutierrez

  There's an article out there, Profiling LAMP Applications with Apache's Blackbox Logs, that describes how to create a log that records a lot of detailed information missing in the common and combined log formats. This information is supposed to help you resolve performance issues. As the author notes "While the common log-file format (and the combined format) are great for hit tracking, they aren't suitable for getting hardcore performance data." The article describes a "blackbox" log format, like a blackbox flight recorder on an aircraft, that gathers information used to profile server performance, missing from the hit tracking log formats: Keep alive status, remote port, child processes, bytes sent, etc. LogFormat "%a/%S %X %t \"%r\" %s/%>s %{pid}P/%{tid}P %T/%D %I/%O/%B" blackbox I'm trying to recreate as much of the format for Nginx, and would like help filling in the blanks. Here's what Nginx blackbox format would look like, the unmapped Apache directives have question marks after their names. access_log blackbox '$remote_addr/$remote_port X? [$time_local] "$request"' 's?/$status $pid/0 T?/D? I?/O?/B?' Here's a table of the variables I've been able to map from the Nginx documentation. %a = $remote_addr - The IP address of the remote client. %S = $remote_port - The port of the remote client. %X = ? - Keep alive status. %t = $time_local - The start time of the request. %r = $request - The first line of request containing method verb, path and protocol. %s = ? - Status before any redirections. %>s = $status - Status after any redirections. %{pid}P = $pid - The process id. %{tid}P = N/A - The thread id, which is non-applicable to Nignx. %T = ? - The time in seconds to handle the request. %D = ? - The time in milliseconds to handle the request. %I = ? - The count of bytes received including headers. %O = ? - The count of bytes sent including headers. %B = ? - The count of bytes sent excluding headers, but with a 0 for none instead of '-'. Looking for help filling in the missing variables, or confirmation that the missing variables are in fact, unavailable in Nginx.

• recovering a broken GNOME-desktop in debian wheezy

  - by morgon

  an hour ago I had a working gnome-desktop on my debian system (thinkpad x121e). Then I installed compiz that crashed. After a reboot the gnome-desktop no longer started. Then I did some upgrades with aptitude, all gnome-packages seem to be there, but it is still not working. On startup I get a login-dialog, when I login there is no desktop, only some window-manager running that allows me to start a terminal. When I run "gnome-session" I get the error message "failed to load session "gnome". So how do I get back to a working desktop? I have tried "tasksel install gnome-desktop --new-install" but that just displays a progress window that after half an hour still shows 0%. Can someone help me please? I have tried "

• Problems executing check_mysql plugin

  - by Brian

  I'm attempting to test out the check_mysql plugin for Nagios using the command line. It works great when I'm just checking localhost but when I try to specify a different server (using the -H argument) I keep getting the following error message: CRITICAL - Unable to connect to mysql://nagios_user@{remoteServerHostname}/ - Access denied for user 'nagios_user'@'{localServerHostName}' (using password: YES) It looks like it's trying to connect to the database using the localhost server even though I've specified a different host name. I've already set up this user on the remote database and they have correct permissions. I'm just trying to figure out why the script keeps inserting the localhost server name instead of the remote one.

• Amazon ELB and use of address / server names across multiple servers

  - by Stpn

  I am setting up Nginx servers behind the ELB. I set up so that api.app.com points to an ELB. I wonder which addresses I should use for remote connections, Nginx settings etc.. 1) For example, in Nginx: Should I do server { listen 80; #What is the right line here: # server_name <WWW.NAME.COM> OR <ec2-.....compute-1.amazonaws.com> OR <MLB-....amazonaws.com>?; passenger_enabled on; ..... } 2) I connect servers behind ELB to remote Postgres database. In Postgres settings should I open the ELB address (MLB-...amazonws.com) or to individual EC2 IPs?

• Linux script to find time difference and send an email if need

  - by Gnanam

  Hi, I'm not an expert in writing shell scripts but also I'm looking for a very specific solution. OS: CentOS release 5.2 (Final) I've a Java standalone which keeps writing (all System.out.println) to a log file. For some unknown reason, this Java standalone stops working at some point of time in my server and eventually logs writing also stops working. I want to have a script which checks the last modified date & time of the log file with current date & time in the server. If the time difference exceeds more than 5 minutes, I want to send an email immediately to my recipients list. This way I'll come to know when this Java standalone has stopped working. I'll move this script to crontab and make it run for every 1 minute, so that this whole process is automated. Log file location: /usr/local/logs/standalone.log

• Secure, efficient, version-preserving, filename-hiding backup implemented in this way?

  - by barrycarter

  I tried writing a "perfect" backup program (below), but ran into problems (also below). Is there an efficient/working version of this?: Assumptions: you're backing up from 'local', which you own and has limited disk space to 'remote', which has infinite disk space and belongs to someone else, so you need encryption. Network bandwidth is finite. 'local' keeps a db of backed-up files w/ this data for each file: filename, including full path file's last modified time (mtime) sha1sum of file's unencrypted contents sha1sum of file's encrypted contents Given a list of files to backup (some perhaps already backed up), the program runs 'find' and gets the full path/mtime for each file (this is fairly efficient; conversely, computing the sha1sum of each file would NOT be efficient) The program discards files whose filename and mtime are in 'local' db. The program now computes the sha1sum of the (unencrypted contents of each remaining file. If the sha1sum matches one in 'local' db, we create a special entry in 'local' db that points this file/mtime to the file/mtime of the existing entry. Effectively, we're saying "we have a backup of this file's contents, but under another filename, so no need to back it up again". For each remaining file, we encrypt the file, take the sha1sum of the encrypted file's contents, rsync the file to its sha1sum. Example: if the file's encrypted sha1sum was da39a3ee5e6b4b0d3255bfef95601890afd80709, we'd rsync it to /some/path/da/39/a3/da39a3ee5e6b4b0d3255bfef95601890afd80709 on 'remote'. Once the step above succeeds, we add the file to the 'local' db. Note that we efficiently avoid computing sha1sums and encrypting unless absolutely necessary. Note: I don't specify encryption method: this would be user's choice. The problems: We must encrypt and backup 'local' db regularly. However, 'local' db grows quickly and rsync'ing encrypted files is inefficient, since a small change in 'local' db means a big change in the encrypted version of 'local' db. We create a file on 'remote' for each file on 'local', which is ugly and excessive. We query 'local' db frequently. Even w/ indexes, these queries are slow, since we're often making one query for each file. Would be nice to speed this up by batching queries or something. Probably other problems that I've now forgotten.

• Postfix, saslauthd, mysql, smtp authentication problems

  - by italiansoda

  Trying to get authentication on my mail server (ubuntu 10.04) running but am having trouble. I have a server with postfix for smtp setup, imap server with courier setup. My postfix authentication is using cyrus (I haven't tried dovecot really) saslauth. The user name and password is stored in a MySql database. Logging in with imap-ssl works on a remote client (thunderbird), and I can read my mail. I can't get the SMTP side working, and have focused the issue down to saslauth. Testing with testsaslauthd -u 'username' -p 'passowrd' -s smtp returns connect() : Permission denied the password in the database is encrypted and I guess this testsaslauthd will take a plain text password and encrypt it. Looking for someone to walk me through getting this working. Im new to the mail server, and have never got one fully working. Thanks. Ask me which log files I should look at/post, which tests to run, permissions to check.

• Icinga/Nagios to ping different machine on local network

  - by feronovak

  I have 3 machines, all remote IPs and all of them running nsclient++ with remote and local IP addresses: 46.*.*.1/192.168.1.1 46.*.*.2/192.168.1.2 46.*.*.3/192.168.1.3 I want nagios/icinga to remotely ping other local machines to see whether VLAN is working correctly. Is there a way to tell nagios/icinga to use machine 192.168.1.1 and to ping 192.168.1.2 and 192.168.1.3 ? check_ping is pinging only machine defined in host_name from icinga server. Icinga is on completely different ip range 92.*.*.* Is there a way to do this to see VLAN workes fine?

• Is it possible to use WebMatrix with pure IIS?

  - by Mike Christensen

  I'd like to check out WebMatrix for publishing our site to IIS automatically (right now, I have to zip it up, copy it out, Remote Desktop into the server, unzip it, etc). However, every example I can find on how to setup WebMatrix involves Azure, or using a .publishsettings file that you'd get from your hosting provider. I'm curious if I can publish to a normal, every day IIS server running on Windows Server 2008. So far, all I've done to the IIS server is install Web Deploy, which I believe is the protocol that WebMatrix uses to publish. When I enter the Remote Site Settings screen, I select Enter settings. I select Web Deploy as the protocol, type in my NT domain credentials (I'm an Admin on that server). I put in the site URL for the Site Name and Destination URL. When I click Validate Connection, I get: Am I doing something wrong, or is this just not possible to do?

• 503 error Varnish cache when eAccelerator is started

  I have a Magento installation running on x-large Amazon server. I have Varnish, memcached and eAccelerator installed on the server. At first everything was working fine, but then at some point it stopped working, throwing 503 error with Varnish cache stamp below it. When I disable eaccelerator, error is gone and site is working. This is my eaccelerator config: extension="eaccelerator.so" eaccelerator.shm_size = "512" eaccelerator.cache_dir = "/var/cache/php-eaccelerator" eaccelerator.enable = "1" eaccelerator.optimizer = "1" eaccelerator.debug = 0 eaccelerator.log_file = "/var/log/httpd/eaccelerator_log" eaccelerator.name_space = "" eaccelerator.check_mtime = "1" eaccelerator.filter = "" eaccelerator.shm_ttl = "0" eaccelerator.shm_prune_period = "0" eaccelerator.shm_only = "0" eaccelerator.allowed_admin_path = "" any hints?

• Rebasing a branch which is public

  - by Dror

  I'm failing to understand how to use git-rebase, and I consider the following example. Let's start a repository in ~/tmp/repo: $ git init Then add a file foo $ echo "hello world" > foo which is then added and committed: $ git add foo $ git commit -m "Added foo" Next, I started a remote repository. In ~/tmp/bare.git I ran $ git init --bare In order to link repo to bare.git I ran $ git remote add origin ../bare.git/ $ git push --set-upstream origin master Next, lets branch, add a file and set an upstream for the new branch b1: $ git checkout -b b1 $ echo "bar" > foo2 $ git add foo2 $ git commit -m "add foo2 in b1" $ git push --set-upstream origin b1 Now it is time to switch back to master and change something there: $ echo "change foo" > foo $ git commit -a -m "changed foo in master" $ git push At this point in master the file foo contain changed foo, while in b1 it is still hello world. Finally, I want to sync b1 with the progress made in master. $ git checkout b1 $ git fetch origin $ git rebase origin/master At this point git st returns: # On branch b1 # Your branch and 'origin/b1' have diverged, # and have 2 and 1 different commit each, respectively. # (use "git pull" to merge the remote branch into yours) # nothing to commit, working directory clean At this point the content of foo in the branch b1 is change foo as well. So what does this warning mean? I expected I should do a git push, git suggests to do git pull... According to this answer, this is more or less it, and in his comment @FrerichRaabe explicitly say that I don't need to do a pull. What's going on here? What is the danger, how should one proceed? How should the history be kept consistent? What is the interplay between the case described above and the following citation: Do not rebase commits that you have pushed to a public repository. taken from pro git book. I guess it is somehow related, and if not I would love to know why. What's the relation between the above scenario and the procedure I described in this post.

• Executing EXE with wildcard from psexec

  I'm writing a few scripts that I am using to integrate with bamboo for some continuous integration improvements and I've run into a bit of a snag. I'm currently trying to run a psexec command that installs the latest build on the remote machine but I dont necessary know the revision number. For example, the remote exe file could be Installer-3.1.xxxxx.exe where the xxxxx changes. I tried running the command with Installer-3.1.*.exe but it takes it as literal in Windows. I'm not overly familiar with Windows command prompt and am more used to Linux at this moment.

• Ubuntu firefox: some web-pages stuck on loading

  - by kristaps.skujins

  Just installed Ubuntu 10.04 beta, installation went fine and all programs are working smooth. Just this one weird network problem. Some sites simply are not opening and loading forever. For example, google.com and youtube are working well, but ubuntu.com and many other are not opening at all, or are loaded partly. One thing i noticed is that on all of those pages on firefox status bar is message "Looking up for www.google-analytics.com" (or similar remote resources) message appearing all the time (even on this page, but it somehow has loaded and working). I should mention that i tried those pages to open on windows OS on this same machine, and they opened without problems. So i am guessing that it has to be some sort of network configuration problems on Ubuntu. What could cause such problem?
