    Are there any specific known steps which I could take to make my computer with Windows XP Professional booting faster? I am interested in speeding up following stages in particular: loading the OS (Windows logo, up to the moment login screen appears) log in user (from the moment you type your user name and password up to the moment all memory resident programs and services are loaded and the computer is really ready to use)

  • smtp(s) proxy to monitor outgoing spam

    - by Zulakis
    I am looking for a smtp proxy to install on our gateway which should monitor outgoing smtp traffic to identify the source of recently occuring spam attacks from our network. It would be enough if this could log all outgoing mails, no actual filtering must be done as I'm going to do this manually. Also, is it possible to monitor smtps ports 465 and 587 or is it necessary to completely block these ports to stop spam?

  • Computer wakes up from hibernation at exctly 3:40am every day

    - by vascoFG
    I'm getting tired of waking up to my computer being turned on, and event log shows that it's waking up everyday at 3:40am and most times won't go back to sleep after the determined 30 minutes (maybe from being in the lock screen?). There are no devices armed for wake, activation timers are disabled and all wake options disabled in the BIOS and energy star 4.0c is enabled (was disabled before but no difference).

  • What logs should I collect from a Windows server network?

    - by Cygnus X
    I'm setting up a log collection server for my Windows network (about 30 servers ranging from 2003 to 2008 R2, and about 300 vista/7 clients), and I was wondering which logs are good to collect and which ones are a waste of time. I'm going to collect the obvious ones (system, security, event, firewall, and role specific logs) but are there any others I should be worried about? I'm using Splunk if that helps answer the question.

    All, I am having intermittent network issues that I am having an issue troubleshooting. The issue is outside of my network on one of the hops in my local area. I was wondering if you all knew of a good windows based program that would monitor/log a tracert or something of that nature. Thanks

  • Need a script/batch/program that runs a command that won't be killed when the parent is killed

    - by billc.cn
    The scenario I use Zabbix to monitor my servers and recently I wanted to add some more metrics for the Windows ones. For security reasons, I used Zabbix's User Parameter feature, but it limits the execution of external commands to about 3 seconds. After that, the command is forcibly killed. I want to run some long run commands, so I used the trick from Zabbix's forum: run the command in the background, write the results to a file and use Zabbix to collect them. This is rather easy under *nix thanks to the "&" operator, but there is no such support in Windows' shell. To make things worse, when Zabbix kills forcibly kill the cmd.exe it used to evaluate the commands, all child processes die including the unfinished background tasks. Thus I need something that can sever all the ties with its children so they won't be affected in the cascading kill. What I've tried start and start /B - They do nothing as the child always die with the parent WScript.Shell.Run as in invis.vbs from StackOverflow - Sometimes work. If the wscript process is forcibly killed as opposed to quitting on its own, the children will die as well. hstart - similar results to invis.vbs At command - This requires you to set an absolution time for the task to run as opposed to an offset, so the code would be quite messy due to the limited shell scripting capability of Windows. (Edit) PsExec.exe from the SysInternals suite - It uses a service to launch the command, so it is not affected by the kill; however, it prints some banner and log info to StdErr and there's no switch to disable this. When I use 2>NUL to redirect them, Zabbix reports an error. After trying the above in different combinations, I noticed if I call hstart from invis.vbs, the command started by the former will be left alone as a parent-less process when invis.vbs is killed. However, since I need to redirect the output, the command I want to run is always in the form of cmd.exe /c ""command" "args"" >log. The vbs also removes all the quotes, so I have to encode the command with self-defined escape sequences. The end result involves about five levels of escaping/quoting, which is almost impossible to maintain. Anyone know any better solutions? Some requirements Any bat/vbs/js/Win32 binary is acceptable Better not require multiple levels of escaping No .Net (including PowerShell) because it is not installed

  • Apache + Passenger, requests not forwarded to Rails

    - by olalonde
    I'm trying to set up Apache + Passenger (mod_rails) and everything works fine except Apache won't forward requests to Rails. From my Apache log: File does not exist: /var/www/rails_apps/domain.com/public/controllerName My Rails app works fine with Mongrel and I also have some PHP/MySQL sites running fine. I have no .htaccess in my Rails app directory. What is going wrong? How could I troubleshoot this problem ?

  • Windows GPO default mapped drives

    - by SteB
    Is there a way, using Windows GPO, to set up a list of "default" mapped drives that can be applied to a group of users? I runs small network and would like to make sure that certain groups of users (like Sales or Support) have the same network shares mapped to the same drive letters irrespective of which PC they log onto. This would make the setup of new users easier and allow the centralised administration of the network locations shared. Any links to examples and/or step-by-step guides would be greatly appreciated.

  • Mac has IP address, can connect to router but can't connect outside

    - by partition
    Weird problem, my MacBook can't connect anywhere right now! The router works, it gets an IP, it can log into to the router but it can't resolve anything! The router works as I connected another device to it and it connected to the net. The MacBook doesn't have any strange DNS configurations either, just 192.168.1.1 for the router I even tried tethering it to my phone, and it still would not connect to the net... help?

  • unable to connect site to different port

    - by JohnMerlino
    I have a domain was registered at godaddy named http://mysite.com/. I logged into godaddy and I went to All Products Domains Domain Management. I clicked on the appropriate domain and it took me to the Domain Details page. I clicked Launch under DNS Manager and it took me to the Zone File Editor. I noticed that notify.mysite.com was pointing to an IP address pointing to a dead server, so I switched it to an operating server. Then I pinged the domain to see where it was pointing to and it was correctly pointing to the working server. So I copied the default configuration under sites-available: sudo cp default notify.mysite.com. And then I made some edits to it to have it point to a different document root to serve files at a different port: Listen 1740 Listen 64.135.xx.xxx:1740 #I also tried this as well: NameVirtualHost 64.135.xx.xxx:1740 <VirtualHost 64.135.xx.xxx:1740> ServerAdmin [email protected] ServerName notify.mysite.com DocumentRoot /var/www/test/public <Directory /var/www/test/public> Order allow,deny allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> Then I enabled the virtual host. Then I went to the document root and added an index.html file with some text in it. Then I restarted apache. The restart gave no errors. Then I type the correct domain in URL: http://notify.mysite.com:1740/ and I get: Oops! Google Chrome could not connect to notify.mysite.com:1740 Somehow it took out all my other sites. Now even the ones that were responding on port 80 are no longe responding, even though I did not touch the virtual hosts for them. I get this message now: Oops! Google Chrome could not connect to mysite.com However, ping responds: ping mysite.com PING mysite.com (64.135.12.134): 56 data bytes 64 bytes from 64.135.12.134: icmp_seq=0 ttl=49 time=20.839 ms 64 bytes from 64.135.12.134: icmp_seq=1 ttl=49 time=20.489 ms The result of telnet: $ telnet guarddoggps.com 80 Trying 64.135.12.134... telnet: connect to address 64.135.12.134: Connection refused telnet: Unable to connect to remote host

  • Exclude all hidden directories in UNIX find

    - by xRickerlx
    I'm doing a word search using the following command: find . -exec grep -q [some_word] '{}' \; -print -o -name .svn -prune -o -name .ssh -prune -o -name .boneyard -o -name log -prune -prune -o -name tmp -prune Is it possible to use a regex to exclude all hidden directories? Note: The current command traverses the entire tree from the current location and exclude those being pruned. The exclusion needs to work for any hidden directory regardless off location.

  • How to determine which request nginx sends to a proxy and which it serves?

    - by Zxaos
    I currently have nginx proxying for Thin, but set up to serve static files for the app that Thin is serving instead of proxying the request. What I'd like to know is how I can check that the rules are set up correctly. Since Thin doesn't log requests, I would need to set up nginx logs in such a way that it shows which requests were served as files and which were passed to Thin. Is this even possible? If so, how?

  • Run script on login with ssh

    - by user912447
    I have a feeling this is quite easy to do but every solution found on google has to do with adding a script to be run whenever someone logs into the machine. What I am looking for is a way to run a script when only I log into the machine. I ssh into a shared computer and need to have it load a couple modules for me and I imagined the easiest way to do this would to just run a script on login. Is there a simple way?

  • How to send Ctrl+Alt+F1 to window (to switch terminal remotely, not locally)?

    - by Vi
    when I press Ctrl+Alt+F{1..12}, it switches me to other virtual terminal. When I have VNC/rdesktop client (and there it is VMWare/Virtualbox with other Linux) I want to switch virtual terminal remotely, but just pressing Ctrl+Alt+F1 switches things locally. VirtualBox/VMWare often provides special means to send Ctrl+Alt+Del, but not Ctrl+Alt+F1. (I already know that I can log in over ssh and chvt)

  • graphical svn client for creating branches, merging branches etc?

    - by ajsie
    hi i wonder if there are some GUI softwares to administrate a svn repo? or do you actually have to log into the ubuntu server with ssh and use all the svn commands to copy the trunk to a branch, merge the data back and forth, copy to a tag, delete and so on... im using netbeans in mac. i think it's only handling the communication between a local project and the repo. not the flows between trunc, branch and tag (creating, deleting, viewing differences etc)
