• Laptop is super slow on network

  - by Gary

  So on our network we have a bunch of wireless macs and window Operating laptops, we have a network setup with 802.11g,b,n. All the laptops seem fine except one which is only getting speeds of 54Mb. I have changed the encryption from AES to TKIP and reset the connection, i have updated the drivers, tried plugging it into the LAN and still same slow speed. Apparently the laptop with the slow speed is fine on other networks. I don't know what to do, can anyone help me?

• Make laptop boot to external monitor

  - by Ozzy

  Hi all. Heres my setup: Dell 1737 2x Dell U2311H The laptop lid is always closed and is wall mounted behind the monitors. Every time i boot the laptop, i have to open the lid a little until it goes to the win 7 logon screen. Once there, i close the lid and both monitors get detected and the laptop screen switches off. As the laptop is wall mounted how ever, its really tedious to keep opening and closing the lid. Is there any way i can make it default to the external monitors permanently? Any suggestions are welcome, even hardware mods. Im willing to rip apart the laptop to install a switch or something if needs be lol

• RESTful applications logic and cross resource operations

  - by Gaz_Edge

  I have an RESTful api that allows my users to receive enquiries about their business e.g. 'I would like to book service x on date y. Is this available?'. The api saves this information as a resource to the following URI users/{userId}/enquiries/{enquiryId} The information shown when this resource is retrieved are the standard sort of things you'd expect from an enquiry - email, first_name, last_name, address, message The api also allows customers to be created for a user. The customer has a login and password and also a profile. The following URIs expose these two resources PUT users/{userId}/customers/{customerId} PUT users/{userId}/customers/{customerId}/profile The problem I am having is that I would like to have the ability to allow users to create a customer from an enquiry. For example, the user is able to offer their service on the date requested and will then want to setup a customer with login details etc to allow them to manage the rest of the process. The obvious answer would be to use a URI like users/{userId}/enquiries/{enquiryId}/convert-to-client The problem with this is is that it somewhat goes against a lot of what I've been reading about how to implement REST (specifically from the book Restful Web Services which suggests that URIs should point to resources not operations on resources). The other option would be to get the client application (i.e. the code that calls the api) to handle some of this application logic. This doesn't quite feel right to me. I have implemented in my design that the client app is fairly dumb. It knows just enough to display the results from the API, and does not contain any application logic. Would be great to hear what others views are on the best way of setting this up Am I wrong to have no application logic in the client app? How would I perform this operation purely in the REST api?

• Taking stock of an existing ASA Firewall

  - by Nate

  Imagine you are given an existing network using an ASA firewall. The network works, but you aren't sure of anything else. The firewall may be completely improperly configured, with "outside" actually being inside and "inside" actually being outside, for all you know. My question is this: what are the commands to take stock of an existing ASA firewall setup? With only CLI access, how do I figure out: What interfaces are available The names of the interfaces The security levels attached to the interfaces The access-lists attached to the interfaces, including rules and directions I know how to set these things (interface, nameif, security-level, and access-list/access-group), but I don't know how to figure them out given an existing system. On a related note, is there anything else that I should worry about checking to make sure that the network isn't wide open? Thanks!

• FreeNAS: Can't access shares on a windows 7

  - by rzlines

  I have just setup a FreeNAS server. I have formatted and added a second hard drive. And mounted the data partition of the first hard drive. I have enabled CIFS and added both the hard drives to the shares. My workgroup is default WORKGROUP, I can see other computers on my network. I can access freenas through my browser that's how I configured it. Got one more question do I need to mount my second drive, if I do what partition number do I put, as it keeps giving me the error of using the wrong partition. Also my second drive doesn't show up on the home page as available as I can only see my first drive's space there.

• How to calculate required switch speed based on network usage?

  - by tobefound

  I have a 48 port HP Procurve Switch 2610 (J9088A) that can handle 13.0 million PPS (packets per second) and features wire speed switching capacity at 17.6Gbps. First off, what does that REALLY mean? Where do I start when trying to figure out if my office (with 70 employees) will be well setup with this switch? How to calculate through-put based on a user average load of X MB per day? 90% of the folks will only be sending email, access random websites, etc... the other 10% will be conducting heavier tasks like moving image files (10 MB) across network shares, constant external FTP streams through the switch to a server etc... Is this switch good enough?

• Wordpress 3 mutli site install

  - by mike

  Hello, Trying to figure out if this is possible... My company has a cms product that was written in Java and we decided to use Wordpress to run blogs for our clients. Obviously, Wordpress does not run on tomcat(at least not by default) so we installed Pound(http://www.apsis.ch/pound/) on our server and have setup any Apache and Tomcat on different ports. When "/blog/" is requested, the request is directed to Apache. This works fine but we would like to use Wordpress multi site so that we can manage all the blogs from a single interface. We would also like the url for every site to be "/blog/" example: http://www.site1.com/blog/ http://www.site2.com/blog/ I'm thinking it would have to be done with apache??? Is it even possible? Thanks!

• Tracking the linux config with git: how?

  - by Pierre

  I'd like to track my linux configurations with git. My idea is to have a branch for each server. /etc is not the only one directory to be tracked (I won't git init in '/etc' ) As far as I could see, it is possible to init a git for a distant directory. I tried this: # mkdir -p /git/.git # cd /git # git --work-tree=/ --git-dir=/git/.git init Initialized empty Git repository in /git/.git/ 1) Creating a new branch before everything is not possible # git branch server1 fatal: Not a valid object name: 'HEAD'. 2) adding a file in master/HEAD is not possible # touch README.md # git add README.md fatal: Unable to create '//.git/index.lock': No such file or directory how should I properly setup git to track my system-config ? Thanks. P.

• Windows Web Server in DataCenter Authenticate with AD in Office

  - by Viper Venom

  Hi, We would like to have put a File Server in DataCentre to allow user to upload/download files when they are home. Since we have hundreds of users and would like to let the user to authenticate with the existing AD in our office. Basically, I will setup the IIS server to allow users to list various directories in the File Server based on their user group. For example, Group A will have list the D:\Files\A and the Group B will have list the D:\Files\B ...etc. After some initial study, I found that the PPTP based Site to Site VPN might fit our need to do the authentication part but I still don't have any idea on how to let them upload files to the server. Is there any suggestions such as any better option to do this (either authentication or upload part) or any area I need to be careful of? Thank you in advance.

• latency, regular alternations. Pfsense, network

  - by Tillebeck

  Any idea why grapgh is a shown? It i two pfsense boxes and I have not looked into where they ping to and if it is related to the server they ping. Trafic graphs are following a normal 24 hour cycle and not related to either of the latency graphs Img1: High frequent ulteration in latency. Just started a few days back. Peaks are not perfectly regular but varies from 40min to 1hour Img2: This is a different router on another internet connection. Most of our routers shown this kind of latency graphs - so for our setup it is "normal". Please note that second graph is for a whole week and not just some hours

If I must use proxy which proxy is better?

• Printer Properties not sending the correct page size to program

  - by Jeff

  We have a Zebra 2844 Label Printer with 4"x3" labels in it. When we check the page settings in Windows XP, it is set to the correct size. When we go to print out of any program, it prints 4"x11". I have checked the page settings in one of the programs that we are using and it does show correctly the 4"x3" settings but prints at the incorrect 4"x11". I have followed the steps here Paper size: Printer Properties vs Page Setup and here Is there a way to programatically set the printer properties in windows? but have not been able to glean enough information to figure it out. If anyone can help, I would appreciate it!

• What is normal SCSI error handling process (scsi_eh_3) CPU time usage?

  - by Kris Jordan

  Last week I got setup with a new dedicated server that is running 4x SCSI drives in RAID 10 on CentOS. The machine is pretty lightly loaded at the moment and has been running for 8 days. The process 'scsi_eh_3' has a CPU time of 13:09.67 in top. This is 3x the next closest CPU time of 4:03.93 for mysqld. Is it normal for the scsi error handling process to use this much CPU time? (Seems like it goes to 0.3% usage ever 5 seconds.) Could this be an indicator that one or more of the drives is having issues?

• HDMI and DVI connected monitors not in dual view on Windows 7 (Intel onboard Gigabyte)

  - by Nux

  I have a HDMI to DVI cable which is connected to one monitor (HDMI is on PC side) and DVI-DVI connected to other monitor. This seems to work up until the system is fully loaded (the startup logo animation is shown on two screens). When and after I log in only one monitor is active (HDMI-DVI). I'm also unable to detect the other monitor (DVI-DVI). Any ideas what might be wrong with the setup? Also when I uninstall the Intel Graphics driver both screens are on, but only duplication works. GA-Z68A-D3H-B3, Intel Z68 Chipset, with fresh VGA driver (15.26.1.64.2618).

• Solaris 10 5/09 can't find SATA disk

  - by anon

  We need to run standard Solaris 10 on a few development servers (Dell 530s) because we can't get a commercial application running on OpenSolaris (we're still trying). However, we are finding that sometimes when Solaris 10 goes to do the install, after setup screens, it can't find the SATA drive. We tried the BIOS setting described here: BigAdmin On some Dells 530s, Solaris GA installs fine, but on others it doesn't. OpenSolaris always installs. Is there some way we can determine (eg. installing OpenSolaris and examining the SATA driver used) what OpenSolaris detected and use some option or driver from it to get Solaris 10 installed on our development Dell servers?

• suppress warnings from windows live mail untrusted cerficate ssl

  - by monkeyking

  Hi we have setup our own mailserver using ssl. Each time I start up windows live mail, in comes up with an annoying message that "The server you are connected to is using a security certificate that could not be verified" Is there some way to add this cerficate such that we wont see this message on every program start. When using firefox (our mailserver can also be webbased) or thunderbird, I get the option to allow the certificate without asking again. I'm perfectly aware that we can buy a certificate that will make the message go away, but this we dont want to do. Thanks edit: I have succesfully imported the certificate such that I can access the website without complains using ie, however the problem still persists in windows live mail.

• How is a Chromebook better than using Chrome browser on another OS?

  - by bigpopakap

  I'm looking into getting a Chromebook as a lightweight device to use for basic functions. I'm fully aware of some of the limitations like no native apps, limited functionality while offline (though this is getting better with Google Drive's offline capabilities). Currently, I have a Windows machine on which I've installed Google Drive, so files in that folder are synced. And I use Chrome as my browser. So I have access to all the same apps (Drive, Calendar, Gmail, Google Music, etc.). Is there any advantage to having a Chromebook over my current setup, other than the speed of the lightweight Chrome OS?

• Force Windows to output only mono sound

  - by J. Polfer

  So, the 'right' half of my pair of headphones broke (the transducer+wire are fine, but the earpiece broke on the headband and so the earpiece won't sit over my ear). So now the right channel is being broadcast to my cube neighbors when I wear my headphones. Yes, they look very silly. Is there a way to ensure, in Windows XP (or Windows Media Player), that all stereo sound is downmixed to the left channel only (ie, in mono) so my neighbors don't hear my music? I know that I can setup the mixer to set the balance to 100% left, but information in the right channel won't be heard.

• puppet agent doesn't retrieve files from master

  - by nicmon

  I have a very basic question regarding to Puppet 3.0.1 configuration. I setup a puppet master server (CentOS) with 2 agents (CentOS and Windows 7), all 3 can ping and access each other. There is no error at all. I have copied a file under /etc/puppet/files/test2.txt my site.pp (/etc/puppet/manifests) contains these lines: node default { include test file { "/tmp/testmaster.txt": owner => root, group => root, mode => 644, source => "puppet:///files/test2.txt" } } but there will no file be created on agent servers under /tmp/ once I run "puppet agent --test" here is the output: [root@agent1 ~]# puppet agent --test Info: Retrieving plugin Info: Caching catalog for agent1.mydomain.com Info: Applying configuration version '1354267916' Finished catalog run in 0.02 seconds "puppet apply /etc/puppet/manifests/site.pp" creates the testmaster.txt under /tmp/ on master.

• Highly Available Web Application (LAMP)

  - by Anthony Rizzo

  I work for a small company who provides a web application for thousands of users. Earlier this year they had one server hosted one company. We recently acquired another server in a different location with the hopes of one day making this a redundant failover machine. I understand what to do with the mysql replication, I plan on using a master-master replication setup, and rsync to sync the scripts and files, however I am at a stand still about how to configure the fail-over. Ideally I would like the two machines to accept requests, like a round robin dns, however if one machine goes down I do not want requests to go that machine. All of the solutions I am come across assumes high availability of servers in the same location, these servers are in two completely different locations with different public ip address. Any help would be great. Thanks

• netsh advfirewall firewall

  - by lehn0058

  I am trying to write a script to configure a windows firewall (server 2008 & 2012 only) to adjust certain firewall settings after a machine has been added to a domain. I need to do this because one of the pre-installed programs on these machines we get only has the firewall rules setup for the public and private firewall profile. This script will be pushed out for other admins to use, and some of the machine will be in other languages. The command to change an existing firewall rule is as follows: netsh advfirewall firewall set rule name = "rule name goes here" new profile=domain This command works great. However, I need to do this for about 10 firewall ports AND since the program could be installed on computers with different languages, I can not just pass the name of all of the firewall rules. Is their some way to do this by supplying the port number? Or some way to specify a regular expression so I could use any rule that has a name LIKE 'test'?

• How did Google get on my Mac?

  - by SamGoody

  Am running a MacBook Pro, and have never installed Chrome, Google Earth, or anything blatantly Google. Just installed Little Snitch (are there no good free firewalls for Mac?) and see that CURL is sending to Google every few minutes, as is a request to Google update and more. Little Snitch doesn't say what program setup these requests. So, how do I find out how G got on my machine, why is it sending so many requests (every minute or so) and how do I remove it (and is it there for reasons other than to help G spy on me)?

• Windows Server 2008 r2 FTP blocking outside connections

  - by nbon

  I have a windows server 2008r2 running IIS 7.5. I am trying to setup a FTP-server in IIS but I'm running into some annoying problems. Setting up the server works fine but when I try to connect from a remote client the connection times out. I have tried to connect to the FTP-server from the localhost and it works flawlessly. I figured that it should be some trouble with the firewall so I went into firewall settings and disabled the Public Profile and my remote connections worked! In my inbound rules there are rules for FTP-connections to allow all profiles etc. I guess they are made automatically when setting up the FTP-server. Anyone got any idea how to allow remote connections without turning off the public firewall?

• Adding multiple websites with different SSL certificates in IIS 7

  - by Timka

  I'm having troubles using SSL for 2 different websites on my IIS 7 server. Please see my setup below: website1: my.corporate.portal.com SSL certificate for website1: *.corporate.portal.com https/443 binded to my.corporate.portal.com website2: client.portal.com SSL certificate issued for: client.portal.com When I try to bind https in IIS7 with the client's certificate, I don't have an option to put host name(grayed out) and as soon as I select 'client.portal.com' cert, I'm getting the following error in IIS: At least one other site is using the same HTTPS binding and the binding is configured with a different certificate. Are you sure that you want to reuse this HTTPS binding and reassign the other site or sites to use the new certificate? If I click 'yes' my.corporate.portal.com website stops using the proper SSL cert. Could you suggest something?
