• Synergy on macbook with osx mavericks wifi connection

  - by user332956

  I'm trying to set up Synergy with my macbook pro running OS X 10.9.3 as a client and my Windows 7 desktop as a server. I'm having some pretty bad connection problems though when I try to use my mac. Every couple seconds the mouse or the keyboard will stop working entirely then come back. I ran some tests and found that the ping from my desktop to my mac would be very high every third ping or so(1000+ ms) or sometimes even time out. If I ping my desktop from my mac the pings are all reasonably low. I believe that this is a power saving feature of Mavericks and I have found a way to get around it by continually pinging my router on my mac, keeping my wifi card from going to sleep. I'm using this right now to type this up with synergy and have had zero issues. Has anyone else ran into this issue and found a better solution? So far, I think my best bet would be to buy an ethernet adapter but I'd rather not have yet another cable running across my desk.

• IDE/PATA high-speed hard drive dock

  - by wfaulk

  I frequently need to access bare drives for backups and need a quick, high-speed way to deal with them. There are a multitude of SATA hard drive docks (for example), but I have a lot of IDE/PATA (hereafter "IDE") drives that I would like to be able to use similarly. There are IDE-to-SATA adapters so you can plug your IDE hard drive into a SATA port, so I don't see any reason why you couldn't use the same technology to have a native dock, yet none seems to exist. Now, I'm aware that 3.5" IDE drives do not have a specification for the layout of the connector, and therefore can't be slapped into a dock the same way a SATA drive could, but 2.5" PATA drives do. In fact, I'm not terribly interested in supporting 3.5" drives. It would be nice, but I deal with them far less frequently than 2.5" drives. Also, I'd very much like for the connection to the computer be faster than USB, preferably eSATA, I don't want to be spending time mounting a drive inside an enclosure, I don't want bare drives lying around with a cable hanging off of them, and I'd prefer a single dock rather than two. What seems like the ideal solution to me would be a regular SATA→eSATA dock and some sort of screwless adapter for IDE drives, but I'm open to any suggestions, regardless of my stated preferences, but which are, in some sort of order of preference: high-speed (faster than USB, at least) holder for drive (not just a cable) no complicated enclosure support for 3.5" IDE drives single dock Updates: Here's a 3.5" IDE to 3.5" SATA docking adapter that could be part of the solution. Weird. I figured that would be the impossible part. I was hoping to find something like this 2.5" to 3.5" SATA chassis that would take a 44-pin IDE drive internally. It looks like the Vantec EZ Swap EX comes awfully close. It has its own bay dock, but it looks like the SATA ports on the back are spaced properly, even if they're not aligned quite properly. Unfortunately, the proper position is at the very edge of the drive, which means that the docks' connectors are at the very edge of their recesses, which means there's no way to fit it in there.

• Server reporting incorrect mime type for css files

  - by Becky

  We have a VPS server that we host our websites on. I have written a CMS using CodeIgniter. On one of the interfaces, I am attempting to upload a css file to the system. This worked correctly when we had it hosted on shared hosting. Since we've moved it to the VPS, I am getting an "incorrect filetype" error. It all comes down to the fact that the server is reporting a mime type of text/x-c for the css file rather than text/css. I logged in via shell and ran the following command on an existing valid css file (to make sure it wasn't an issue with either CodeIgniter or with php). file --brief --mime 'filename.css' 2>&1 The server gave me the following in response to my command: text/x-c; charset=us-ascii My question ... is there some sort of server setting that I need to tweak to get the server to correctly identify the css file as text/css? Do I just have to add a mime type for the css files to the server? I found the mime types file (etc/mime.types), and it just hase video types and a couple other that I have no idea what they are. There is nothing in there for css or images or html files. Unless I'm looking in the wrong spot. I'm not a server person, so I'm hoping someone can help me out. Some server specs: Apache/2.2.22 (Unix) php 5.3.13 Server API = CGI/FastCGI the fileinfo php extension appears to be disabled

• Terminal server performance over high latency links

  - by holz

  Our datacenter and head office is currently in Brisbane, Australia, and we have a branch office in the UK. We have a private WAN with a 768k link to our UK office and the latency is at about 350ms. The terminal server performance is reeeeealy bad. Applications that don't have too much animation or any images seem to be okay. But as soon as they do, the session is almost unusable. Powerpoint and internet explorer are good examples of apps that make it run slow. And if there is an image in your email signature, outlook will hang for about 10 seconds each time a new line is inserted, while the image gets moved down a few pixels. We are currently running server 2003. I have tried Server 2008 R2 RDS, and also a third party solution called Blaze by a company called Ericom, but it is still not too much better. We currently have a 5 levels dynamic class of service with the priority in the following order. VoIP Video Terminal Services Printing Everything else When testing the terminal server performance, the link monitored using net-flows, and have plenty we of bandwidth available, so I believe that it is a latency issue rather than bandwidth. Is there anything that can be done to improve performance. Would citrix help at all?

• Exchange eMails In A Mailbox Appear To Be Blocked By A Dud Message

  - by John Judd

  I have a client with an Exchange server on which there are quite a few mailboxes. One mailbox in particular is causing some problems. When an email from a certain address arrives, it appears to prevent Exchange from successfully delivering the email to the Outlook Express inbox. The address in question is from an account with Bigpond, or at least I think it is, I didn't check to see if it was spoofed (only just occurred to me.) Any emails in the queue before the suspect email are delivered, then Express times out. When send/recv is retried those emails are re-received and the process times out again. The process I have for fixing this is to log in to the sever, load Outlook, open the recipients inbox, and delete the suspect email. Then retrying the send/recv on Express successfully retrieves all the messages (except for the deleted message.) This solves the immediate problem, but this has happened several times now, and each time requires the process above to correct it. What I am wondering is if there is anything I can do to fix this permanently. It seems to me that Exchange should reject a dud email message rather than getting stuck. Does anyone know what could be causing this, and how I can fix it?

• What is optimal hardware configuration for heavy load LAMP application

  - by Piotr K.

  I need to run Linux-Apache-PHP-MySQL application (Moodle e-learning platform) for a large number of concurrent users - I am aiming 5000 users. By concurrent I mean that 5000 people should be able to work with the application at the same time. "Work" means not only do database reads but writes as well. The application is not very typical, since it is doing a lot of inserts/updates on the database, so caching techniques are not helping to much. We are using InnoDB storage engine. In addition application is not written with performance in mind. For instance one Apache thread usually occupies about 30-50 MB of RAM. I would be greatful for information what hardware is needed to build scalable configuration that is able to handle this kind of load. We are using right now two HP DLG 380 with two 4 core processors which are able to handle much lower load (typically 300-500 concurrent users). Is it reasonable to invest in this kind of boxes and build cluster using them or is it better to go with some more high-end hardware? I am particularly curious how many and how powerful servers are needed (number of processors/cores, size of RAM) what network equipment should be used (what kind of switches, network cards) any other hardware, like particular disc storage solutions, etc, that are needed Another thing is how to put together everything, that is what is the most optimal architecture. Clustering with MySQL is rather hard (people are complaining about MySQL Cluster, even here on Stackoverflow).

• Virtual host config issues in osx 10.7 server app

  - by Benno

  I have two mac mini lion servers setup to run as production and staging machines. My sysadmin decided on these machines over the previous CentOS we had because it had an "interface" to be able to manage it, rather than just the terminal. To be honest, I prefer the terminal. My problem is, the mac osx 10.7 server.app seems to be having issues with the creation of virtual hosts in the 'Web' section. It seems VERY touchy. For example, I cannot create a http virtual host first. I have to create a https host first with a unique dns name 9e..g vuly6), then create the http host with a different dns name to the first (e.g. www), or it appears to override it the first one, even though one is ssl and one is non-ssl. Further, it seems to override perfectly good configurations at random. For example, the default sites directory is usually /Users/default/Sites/Customsites or something, but sometimes when I load the server.app it changes to /var/empty. Also, if I change or add extra virtual hosts after the first one or two, it starts to mess up and the first two virtual hosts start having issues. Has anyone had any experience with setting up virtual hosts via this app? Am I able to manually create these virtual hosts, without using the app, and without the app overriding my settings when I restart apache?

• postgresql No space left on device

• Desktop.ini Issues/Confusion

  - by EpicDavi

  BACKSTORY: I was out of town for a while and I forgot to turn my computer off. When I came back I saw that a desktop.ini file was on my desktop (using Windows 7). I thought that was odd because I knew it was a system file and it usually didn't show up due to the fact that I had disable the feature to show system files. Also it wasn't translucent like the other system files. I went to my control panel and saw that the "Hide protected operating system files" was indeed enabled. This puzzled me so I disabled the setting and another one was on my desktop like it usually is hidden. So now I have to desktop.ini files on my desktop: one hidden and one not hidden. I am doing an antivirus check to see if anything was going on and I will give an update soon. I am pretty sure these files are harmless and could be deleted but I would rather get another person's opinion on the subject. Thanks! UPDATE: I did an anti-virus scan and it seems I have no problems. It is odd because the file seems to maintain system file properties such as not being able to be edited and other things. Also I have tried restarting my computer and it is still not hidden. So the question remains: What should I do with the file and what caused it?

• Configuring OS X L2TP VPN to use Certificate for IPSEC layer instead of Pre Shared Key

  - by Matthew Savage

  I'm trying to setup a L2TP VPN on an OS X Snow Leopard Server setup, and have had success using a pre-shared key, however I would rather not rely on a simple string, and use a certificate instead. Setting this up on the server side is seemingly easy, you simply select a certificate you have generated from the list, and hit apply, however when I try to use the certificate on the client side it fails. I have exported the certificate into a P12 file, and then transferred to the client, and imported into the login keychain, however when I try to choose the certificate (from Network preferences, clicking Authentication Settings, then selecting Certificate and pressing Select) I am shown the following error: No machine certificates found Certificate authentication cannot be used because your keychain does not contain any suitable certificates. Use Keychain Access to import the certificate into your keychain. If you do not have the certificates required for authentication, contact your network administrator. Unfortunately even when I try to generate a certificate where I override the defaults, ensure the DNS name etc are set properly this doesn't change. When I select Certificate Authentication for the User Auth, and click Select the certificate for the server shows up there, but obviously this isn't where I need it to be available.

• Remote desktop solution where the desktop sharing party contacts the computer it wants to share with

  - by Kent

  I'm in a situation where I act as a sort of techinical support to my family and less techinically experienced friends. I'm looking for a remote desktop solution where it's possible to setup a "zero-install, double click an icon"-solution where the client computer contacts me so that I may interact with their desktop. The last part is important as the people in need of my help don't know how to configure their router or even the firewall software on their own computer. They are able to click an accept button when asked if a program should be able to make outgoing connections. They have many different kinds of routers, as well as software firewalls, and I rather not deal with the problem of how to connect to them using whatever as well as the actual problem they are having. It must be: Free of charge for non-commercial use. Possible to use it in a mode where the computer wanting to share its desktop should be able to make a connection to my computer. My computer has a DNS name we can use. Compatible with both Windows XP and Windows 7. Independent of a third party server or infrastructure. Explanations of the above: I don't want to spend money on it when I help them for free. If it's free as in freedom, all the better! I guess this boils down to being callable like showdesktopto.exe opscomputer.com where opscomputer.com is my computers DNS name. If that is possible then I can create a shortcut they can use to connect to me when they need help. It's nice if it's possible to specify a password or key file which I can use to authenticate myself, but it's not required. They use the OS which their machine comes installed with. That means Windows XP or 7. I want something which will work in the long run. Using a third party service which might not be available when I need it disqualified such solutions.

• copSSH and cygwin - Can't use windows style paths

  - by DrFredEdison

  I setup copSSH on one of my windows servers, and within the copSSH bash shell, I can't seem to use windows-style paths to remove and copy files. If I do try, I get the following: $ /bin/cp -r C:/Domains/_temp/collage_push/* C:/Domains/collage/ cygwin warning: MS-DOS style path detected: C:/Domains/_temp/collage_push/ Preferred POSIX equivalent is: /cygdrive/c/Domains/_temp/collage_push/ CYGWIN environment variable option "nodosfilewarning" turns off this warning. Consult the user's guide for more details about POSIX paths: http://cygwin.com/cygwin-ug-net/using.html#using-pathnames I have created a windows environment variable CYGWIN set to nodosfilewarning. It has no effect. I added export CYGWIN=nodosfilewarning to my .bashrc and doing a echo $CYGWIN in my ssh session confirms it is indeed getting set; yet again, it has no effect finally, I noted that when not doing my own export that CYGWIN contains "nontsec binmode" (no quotes), so I tried: export CYGWIN="nodosfilewarning nontsec binmode" in my .bashrc and still no dice. Older versions of CopSSH didn't have this issue. How can I actually override this error? I have a lot of scripts that already use windows-style paths, and I'd rather not change them if possible.

• LAMP server VM issues

  - by nullArray

  After getting a recommendation to salvage a wiki by installing a LAMP server, I went on the prowl for a good virtualized one. I used the VMware Player version. Since the windows box has Bonjour, I can, for example, go to http://lamp.local. and it works see the web client. The problem is, I can't ssh to a directory to scp the files I need, mount a usb thumbdrive (usbfs is unsupported) nor get samba working. I can't even update the ubuntu installation, it fails. I've tried bridged, nat and host-only networking settings in VMware Player. Bridged gives me an undefined IP, while the other two each have different IPs. All three settings allow me to access the web config, but none of them give me samba access. Windows usually freezes, then reports that it cannot connect. I'd rather not wipe a box to do a dedicated install, is there I way I can get this VM working, or are there better LAMP VMs out there? This one came already working and set up with VMware Player, so I thought it would be perfect... Thanks,

• Changing order of Thunderbird email address autocomplete?

  - by Brooks Moses

  I recently did a system wipe and installed Thunderbird 3.0, and imported all of my email setup from a previous Thunderbird 2.0 installation. Almost everything is working fine, but I'm having a problem with the autocomplete in email addresses when writing messages. The relevant behavior is this: In the old 2.0 installation, the autocomplete appeared to know which email addresses I used most frequently, and so when I typed "m" in the address line, it would pick as the default selection the "m"-person who I frequently write email to. (It's possible this is an illusion and it simply picked people in the order I added them to my address book.) Thus, I have become used to typing "m"-"enter" in the address field, and getting this person. In the current 3.0 installation, however, the autocomplete order has changed. It's not the same as it was, and it's not alphabetical. The result is that I'm spending extra time looking at the email address bar, and more annoyingly, half the time the old muscle-memory kicks in and I find myself with an email that's addressed to a couple of customers rather than to my boss and coworker. Thus, two questions: How does Thunderbird determine this autocomplete order, among a set of addresses all of which are in the same address book? How can I change this ordering to be what I want? (I have tried Google-searching, and found a number of incomplete answers, nearly all of which were for version 1.0 or thereabouts, and reference settings dialog boxes that no longer exist.)

• Change which server mailbox is associated with in Exchange 2007

  - by tacos_tacos_tacos

  I have restored and mounted an EDB file onto a new Exchange 2007 Server. However, the old server is still online and although all the mailboxes I need are in the newly-mounted database, in Exchange 2007 System Manager it still shows that the mailbox is associated with the old server. If I try to "Move" the database it actually tries to copy the files from the old server to the new server, which is not necessary because they are already there - and produces and error about the mailbox on the destination already existing. How can I simply tell Exchange (AD?) to use the new server to find the mailbox rather than the old? Edit: I did the restore by taking the old server offline (turning off all Exchange services), copying EDB file to the new server, restoring it with eseutil, and mounting it to the new server. I did it this way in part because I didn't know a better way and in part because I couldn't use move-mailbox as the source location had a horrible Internet connection (which is why Exchange is being moved to the new location). I had to copy the EDB from the old server to a hard disk, go somewhere with a better Internet connection, upload the EDB to the new server.

• How to enable the 2 concurrent (+1 console) sessions on Windows Server 2012

  - by Dai

  I have a Windows Server 2012 VM running on Windows Azure. I want to enable the ability for 2 simultaneous administrative sessions over Remote Desktop. This is permitted under the EULA for Windows Server 2012. This is NOT the same thing as the fully-blown Terminal Services / RDS feature. In Windows Server 2000 and 2003, multiple concurrent sessions (up to a limit of 2, plus the root /console session) were enabled by default (such that logging-in via RDP without logging-out first would create a new session rather than reconnecting to the old session). In Server 2008 and later it uses single-sessions by default, as this simplifies administration (as most people want to connect to old sessions). In Windows Server 2008 R2, you can add the MMC snap-ins for Remote Desktop Host Configuration which allows you to re-enable concurrent sessions. However, in Server 2012, after adding the Remote Administration snap-ins from Server Manager it seems the Remote Desktop Host Configuration snap-in has been removed. How can I re-enable the multiple concurrent sessions for Remote Desktop for Administration in Windows Server 2012?

• How to wake from screensaver directly to the login screen in Ubuntu

  - by torbengb

  (a.k.a. How to switch users without entering password, part II) (see part I) I've got Ubuntu 9.10 with a user account for my wife, and one for myself. "Wake-from-screensaver" should result in "choose user" without having to enter any password. I know how to do that in Windows, but I'm not good with Linux (yet). Part of this was answered in my earlier question which helped me get past the login screen without passwords (after booting, and after choosing "switch user"), but once the screensaver kicks in and I wake it up again, the system does not present the "choose user" screen. Instead, it either turns off the screensaver and presents the desktop of the most recent user, or (if the screensaver is set to lock the screen) prompt for the user's password (which can be handily surpassed by clicking the "switch user" button and choosing the same user again). So, the login ("choose user") screen has been dealt with. How do I make the (any) screensaver return to the login screen at wake, rather than to the current user's desktop? Windows can do this, I'm sure Linux can too - but how?

• How to deduplicate 40TB of data?

  - by Michael Stauffer

  I've inherited a research cluster with ~40TB of data across three filesystems. The data stretches back almost 15 years, and there are most likely a good amount of duplicates as researchers copy each others data for different reasons and then just hang on to the copies. I know about de-duping tools like fdupes and rmlint. I'm trying to find one that will work on such a large dataset. I don't care if it takes weeks (or maybe even months) to crawl all the data - I'll probably throttle it anyway to go easy on the filesystems. But I need to find a tool that's either somehow super efficient with RAM, or can store all the intermediary data it needs in files rather than RAM. I'm assuming that my RAM (64GB) will be exhausted if I crawl through all this data as one set. I'm experimenting with fdupes now on a 900GB tree. It's 25% of the way through and RAM usage has been slowly creeping up the whole time, now it's at 700MB. Or, is there a way to direct a process to use disk-mapped RAM so there's much more available and it doesn't use system RAM? I'm running CentOS 6.

• SQL Server on Linux

  - by TimothyAWiseman

  For a particular project that is coming up, I am trying to expand my knowledge of Linux, so I am going to set up a Linux system at home. Rather than dual booting, I am thinking about putting SQL Server on a Windows Virtual Machine with Linux as the host at least until this project is over when I will probably switch back to Linux. So, I have a couple of different, but interrelated questions: How well does this work? This is only a test machine at home, so I can easily accept a fair bit of degradation, but if it is going to be a horrible reduction in performance I will dual boot instead. Is there a particular virtual machine manager I should look at to go this route? Since this is my personal machine, price is an issue but I am quite happy to pay a reasonable amount. And finally, given the choice of VMM, is there a particular Linux Distro I should be looking at? [This has been cross posted at Ask.SqlServerCentral.com . I think it may be appropriate at both sites. ]

• SQLVDI error - attempt to release mutex not owned by caller

  - by Chris W

  I've started getting some errors in the App event log of one of our database servers (Windows 2003 & SQL Server 2005). The nightly full database backups are completing successfully however immediately after the job success is written to the event log there is a run of entries that say: SQLVDI: Loc=CVDS. Desc=Release(ClientAliveMutex). ErrorCode=(288)Attempt to release mutex not owned by caller. There's five of these logged - the server itself has more than 20 databases on it which are all backed up successfully. The server is backed up by Bacula using a VSS backup. Has anyone got any ideas what would be causing the errors? They seem to have started after a re-boot on Friday to install some patches which included KB960089. Edit: After getting the errors for a few days they've now stopped without any action on my part other than letting the backups continue as they were. It may be a coincidence but they stopped after Bacula completed its weekly full rather than the daily incremental backup.

• Importing csv list of contacts into Exchange 2007 GAL and create Distribution Group

  - by Ken Ray

  Here's the situation: We have a list of about 1,000 contacts (Lawyers in the area our court serves) with name and email address. I've been asked to create an email distribution list that can be used to sent emails to all of the external users on that list. I've seen various articles using the Exchange Management Shell and the Import-csv command piped through a ForEach-Object to a New-MailContact to set up the contacts. However, Exchange Management Shell is rather unhelpful, and it isn't working. What I believe I need to do is: 1) Set up a new distribution group using the Exchange Management Console. Let's say this new distribution group (which appears in the list of Distribution Groups under Recipient Configuration) is called "FloridaBar". 2) Make sure I have a csv file of the information I want to import. 3) Open Exchange Management Shell, and enter the following command: Import-csv C:\filename.csv | ForEach-Object { New-MailContact -Name $."NameColumnName" -ExternalEmailAddress $."EmailAddressColumn" -org FloridaBar Now, creating 1,000+ contacts in active directory - I assume that shouldn't be an issue. Do I have the "-org" parm wrong? Do I need to spell out the complete organization unit name (my.domain.name/Users/FloridaBar)? Is there a better way of doing this? Thanks in advance Ken

• Replacing local home server with VPS: Suggestions?

  - by CamronBute

  So right now, I'm running an old box with a 2TB HDD in it. I use this as a file server for the home network, as well as a box for downloading large files which are synced via Dropbox. Lots of other tinkering things, too. Basically, I'm sick of paying extra for the power and having to worry about drive failures and whatnot. I'd rather get a remote server, let someone else manage it and provide access from the Internet. So, I've been looking for a Windows VPS that would give me access to install things and tinker, and I'm having a problem finding a host that offers more than 100GB of hard drive space. If they do offer a package with 100GB of storage, everything else is waaayyyy more than what I actually need. The idea is to create a permanent VPN connection from the cloud server to my home network to provide a transparent solution so I'm not having to go to lengths to transfer files or whatnot. I think a VPS solution will allow me to do this. I would like 1TB of storage space, minimum 100Mbps Internet connection, minimum 250GB bandwidth, admin access. Anyone have anything? Or am I being unreasonable? If I am, why?

• Windows won't sleep after booting from grub

  - by mkasberg

  I recently added a second hard drive to my computer and I am using it do dual-boot Linux (Ubuntu 12.04) with Windows 7. Both hard drives are SATA. I am using the default grub bootloader on my second hard drive. The windows drive is unmodified. To get to grub, I changed the hard disk boot priority in my BIOS (P35-DS3L) to boot from the second drive. The problem I'm having is that when I boot to Windows 7 (on sda) from grub (on sdb), Windows 7 will not go to sleep (from the start menu). The display shuts off momentarily as if its going to sleep, then comes back on and displays the switch-user screen. Powercfg -lastwake does not show anything. I am sure that this is related to booting from grub on sdb because when I change the hard disk boot priority in the BIOS to boot from my (unmodified) Windows hard disk, the computer goes to sleep fine. It occurred to me that installing grub on sda might solve the problem, but I'd rather not since I like to have my windows hard disk unmodified so that booting to it from the BIOS boots directly to windows. A possible work around is to use the BIOS as a bootloader, by pressing F8 to select the boot device. Still, I'd like to know why the problem is happening in the first place.

  I'm using squid 2.6.22 (Centos 5 Default) as a proxy. Squid seems to break the authentication process for web pages when they require NTLM or Kerberos Auth. I tested with sharepoint 2007 and tried all 3 authentication methods (NTLM, Kerberos, Basic). Accessing the site without squid works in all cases. When I access the same page with squid, then only basic-auth works. Using IE or Firefox desn't make any difference. Squid itself can be used by anybody (no auth_param configured). Its a bit tricky to find solutions online, since most of the topics whirl around auth_param for authenticating users to squid rather than authenticating users to a webpage behind squid. Could anyone help? Edit: Sorry, but my first test was totally screwed up. I tested against the wrong webservers (Memo to myself: always check assumptions before testing). Now I realized that the problem scenario is completely different. Kerberos work for IE Kerberos works for Firefox (after changing "network.negotiate-auth.trusted-uris" in about:config) NTLM works for IE NTLM does NOT work in Firefox (even after changing "network.automatic-ntlm-auth.trusted-uris" in about:config) By the way: The feature that provides NTLM-passthrough in squid is called "connection pinning" and the HTTP header "Proxy-support: Session-based-authentication""

• Most transparent way to connect two LANS using a WET610N Wireless Bridge

  - by Spencer Ruport

  I have two wired systems hooked to a Linksys WRT54GL wired/wireless router which is also hooked to my internet. I'll refer to this as LAN1. I have two more systems in another room that are connected wirelessly. Recently I decided I would much rather have another wired LAN in the other room and use a bridge to connect them. This would be LAN2. Prior to hooking up the device I assumed that the ethernet side of the bridge would have a DHCP server so that I could simply hook it up to a switch and I'd be on my way. However that isn't the case which leads me to believe I'll have to add one to LAN2 correct? Or is there some way to have the DHCP from LAN1 also hand out IP addresses to LAN2? If I do need a DHCP device on LAN2 what would be best? Another hardware device or should I just install some DHCP software on one of the systems (since they're both on 24/7 anyway). Any recommendations would be appreciated. :)
