• Apache / PHP Begins to Deny SQL Requests after about 2000

  - by Daniel Stern

  We have a web page on our server that we use to run administrative scripts. For example, we might run the script "unenrolStudents()" which runs 5,000 SQL SET commands one after another and sets 5000 student entries in an SQL database to unenrolled. However, we are finding that after running a few thousand queries (it is not totally consistent) we will be "locked out" by our server. SYMPTOMS OF LOCKING OUT: - unable to connect to server with winSCP - opening putty with that connection shows a blank screen (no login / pass) - clearing cookies / cache in chrome does NOT fix locking out - other computers in the office ALSO become locked out - locking out can be triggered with a high frequency of requests (10000 in 1 second) or by less over time (10000 in 500 seconds - this will still cause a lockout even though the frequency is much less) We believe this is a security feature of our own Apache. I know we are using Suhosin but I didn't configure it so I don't know. How can I disable this locking effect so that I can confidently run all my SQL requests and they will go through? Has anyone else dealt with this and found workarounds? Thanks DS

• Seeking web-based FTP client for very large file upload

  - by Paul M. Nguyen

  I have looked around for these for some time... the limits imposed by the web server and/or the dynamic programming environment (e.g. PHP) are far too restrictive for the application I'm working on. We need to be able to move large graphics and video files to and from clients (ranging from tens of MB to a few GB in a single file). Plain FTP with a proper desktop client will do the trick, and we're hosting this in Amazon EC2 with EBS. User management will be done from the office via webmin. Users are chroot-jailed into their home dir by proftpd. net2ftp will work for many clients, but we often need to move single files that approach 1GB or exceed 2-3GB which is way out of the range of any http-based uploader. So we turn to Java or Flash - can they do it? From within the web browser establish an FTP connection and grab a huge file? There are licensed applets and such out there, but none seem convincing. Again, I'm looking for some code that can speak FTP and read (& write?) the local disk, that is delivered in a web browser, and can move single files of 2GB+. The reason for having a web-based interface to FTP is to skip the software installation step for our clients. I will consider proper desktop client software as long as it's "portable" and at least Win+Mac and can be easily configured by lay-man users in a hurry.

• Surface (Pro) Soft Keyboard + Hardware Keyboard Issue

  - by Matt Clark

  When I got my Surface Pro 2, I loved it, and everything seemed to work flawlessly, until, wait for it, windows updates... The issue that I am having is the following, I primarily use the TC (TypeCover), as the Pro is an out-of-office laptop replacement for me, that I can still use to do whatever I need, but there are times when I will flip the cover, and use the system in tablet mode. The problem is that even when the TC is attached, any text field I click on, causes the OSK (on screen keyboard) to appear, as if I was running the system in tablet mode. As soon as I press a single button on the TC, the OSK is dismissed. When I first got the system, this was NOT the case, and it functioned as it should, where the OSK will only appear if the TC was not present. The biggest problem that I am having is the fact that the OSK causes the windows to be resized. Maximized windows will be shrunk, and stretched to their previous state, however a window that is not maximized will stay in its shrunken state, after the OSK has been dismissed. Below are pictures that show what is happening. Has anyone else experienced this issue? And is there any way to fix it? As you might imagine, having spent a pretty penny on a device like this, it it quite an annoying bug that needs fixing. I have been dealing with this issue for about 3 months now.

• Outlook 2010 OSC with SharePoint 2010 documentation or help

  - by skypanther

  I'm looking for documentation or help to set up Outlook 2010's social connector to work with SharePoint 2010. I can't find much info other than some MS videos and blogs saying that it's possible. They say "we are already connected to SharePoint, so let's add in the XYZ connector..." but don't tell how they connected to SharePoint. Server A: Win2K8 x64, Exchange 2010 x64, domain controller Server B: Win2K8 x64, domain member, SQL Server 2008 R2, SharePoint 2010 Client: Win 7, domain member, with Office 2010 RTM (most every component installed, including the OSC) I've added my domain users to a group. In SharePoint, I granted that domain group permissions to access the site. As any of the domain users, I can use IE to log on the My Sites pages. From there, I can add lists, blog posts, status updates etc. In Outlook, I can add a SharePoint contact to my Contacts list. But, all I see in the People Pane is emails my users have exchanged. I don't see any of the other SharePoint status updates. When I try to use the "Add this person to a social network" link to connect them with my My Sites, the process fails. It doesn't give any sort of error message that helps me figure out why. Just a "Try Again" button that likewise fails. Any guides, links, suggestions? I'm pretty novice-level with SharePoint but mildly adept with the other technologies.

• Printing to a remote printer through the internet

  - by Lock

  I have a remote network (A) that is connected to a head office (B) through a private network. Network A only has 1 PC that requires the connection, and this is into a terminal server at network B. We want to save money by getting rid of the private network as only 1 PC now access it and it seems silly to pay ~$400 per month for something that is accessed by 1 PC. A VPN tunnel is out of the question as the provider wants to charge $600 a month for a VPN tunnel (more than a private network? I might get them to check these numbers). I was thinking of 2 options: 1) VPN client on the PC. This wouldn't cost a thing as we already have VPN users available. 2) Open up a port on the firewall of network B, forwarding to the terminal server. Now the problem is this: On the terminal server, the program that is accessed is for printing labels to the printer that is at network A. The program is setup to send all print jobs to a printer that is setup locally on the terminal server, which has its port mapped to the IP address of the printer that is at network A. If we got rid of the VPN tunnel and used clients/open up firewall port, the printer would no longer be able to find network A, and hence printing would not work. Any ideas to combat this issue? Can the printers at the remote network be setup as internet printers? I've never had any experience with internet printers. Can you open up ports and map to a public static IP address?

• Internet slowed down because of SQUID Server setup

  - by Ranjith Kumar

  Recently I have setup a squid server for our office. I have computer (A) with two ethernet cards, one for internet and the second one for local networkIt has Ubuntu server OS with squid-server and dhcp3-server installedI have added few iptable rules to work like a router and redirect all http traffic to 3128 port This link is my reference. Everything worked fine for 2 days. All of a sudden internet speed went down drastically. When I connected the internet cable to my laptop to test the internet speed it was fine. Again when I reconnected it back to computer A everything was normal. This happened 4 times in a week. Could anyone here please help me why the internet speed is going down and it becomes normal when I reconnect the cable. EDIT: Rebooting the system (computer A) didn't make a difference. I have changed iptables so that http traffic doesn't redirect to 3128 port any further, still no change in the internet speed. I think the problem is not with squid but with something else. Here are my iptable rules SQUID_SERVER="10.1.1.1" INTERNET="eth1" LAN_IN="eth0" SQUID_PORT="3128" PROXYSERVERS=(Atlanta Baltimore Boston Chicago Dallas Denver Houston KansasCity LosAngeles Miami NewYork Philadelphia Phoenix SanAntonio SanDiego SanJose Seattle Washington) SERVERLEN=${#PROXYSERVERS[*]} I=0 iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X modprobe ip_conntrack modprobe ip_conntrack_ftp echo 1 /proc/sys/net/ipv4/ip_forward iptables -P INPUT DROP iptables -P OUTPUT ACCEPT iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT iptables -A INPUT -i $INTERNET -m state --state ESTABLISHED,RELATED -j ACCEPT iptables --table nat --append POSTROUTING --out-interface $INTERNET -j MASQUERADE iptables --append FORWARD --in-interface $LAN_IN -j ACCEPT iptables -A INPUT -i $LAN_IN -j ACCEPT iptables -A OUTPUT -o $LAN_IN -j ACCEPT while [ $I -lt $SERVERLEN ]; do iptables -t nat -A PREROUTING -i $LAN_IN -p tcp -d ${PROXYSERVERS[$I]}.wonderproxy.com --dport 80 -j ACCEPT let I++ done iptables -t nat -A PREROUTING -i $LAN_IN -p tcp --dport 80 -j DNAT --to $SQUID_SERVER:$SQUID_PORT iptables -A INPUT --protocol tcp --dport 80 -j ACCEPT iptables -A INPUT --protocol tcp --dport 443 -j ACCEPT iptables -A INPUT --protocol tcp --dport 22 -j ACCEPT iptables -A INPUT -j LOG iptables -A INPUT -j DROP

• 2000 Server, User can't logon

  - by Mike I

  I hope you can help me. I recently upgraded a workstation at my office (to a whole new machine) and ran into a pretty serious problem. Friday until 5:00 PM, I could access my mail on 2000 Exchange server. When I shut the old workstation down and put in the new workstation, I tried to set up an account. When I put the server name in appropriate field and typed my username and hit check names, my username does not come up. So to troubleshoot, (It also is a SMB server) I try to logon to my file share. (My local credentials are the same as server credientials of user account) When I try to logon to share, I just get the Username/Password screen (Never had gotten that before since credentials are the same) Again, in troubleshooting mode, I try to log on to my user from another workstation. Still can't authenticate via my user. Every other user can authenticate and load up their shares/mailboxes. I have restored Exchange from the backup as of 3 days ago (Thursday) but the exact same issue is still there. I really do not understand what is wrong and what else I can do to troubleshoot. If anyone has some pointers for me, I will surely accept them. Thanks, Mike

• who has files open on a linux server

  - by Robert

  I have the fairly common task of finding who has files open on our Linux (Ubuntu ) file server in our Windows environment. We use Samba on the network and I use Putty from my workstation to establish a shell window to run bash scripts. I have been using something like this to find what files are open: (this returns a list of process ids with each open file) Robert:$ sudo lsof | grep "/srv/office/some/folder" Then, I follow up with something like this to show who owns the process: (this returns the name of the machine on the network using the IP4 protocol who owns the process) Robert:$ sudo lsof -p 27295 | grep "IPv4" Now I know the windows client who has a file open and can take action from there. As you can tell this is not difficult but time consuming. I would prefer to have a windows application I can run that would just give me what I want. So, I have been thinking about creating some process I can run on Linux that listens on a port and then returns a clean list of all open files with the IP address of the host who has the file open. Then, a small windows client application that can send the request on the port. It seems like this should be a very common need but I can not find anything like this that has been done before. Any suggestions?

• Programmer configuring a new network

  - by David Lively

  I'm in the process of expanding my home network from a couple of laptops on a wireless Verizon FiOS router to include: Linksys 24-port switch Cisco Pix 515 Cisco 3640 router One new development desktop and three new machines to act as a db server, web server and a backup system. My company is moving offices and we've decommissioned some older hardware, which I was able to pick up for the cost of the labor to move it home from the office. The benefits to working with dedicated web and db servers are very valuable to me. I know very little about network topology, other than that everything plugs into the switch, which then plugs into the cheap Verizon router. (Verizon provides a coax connection that the router must translate into Ethernet before I can use it with any of this equipment). Questions: What is the recommended topology for this equipment? Verizon router - Pix - 3600 - switch? Is the 3600 even necessary or desirable? The Verizon router has one WAN port and 4 client ports, all 10/100. Is there any performance benefit at all to wiring multiple connections from the verizon router to the switch, assuming I don't use the Pix? Should I use the Pix? Software firewalls are a pain, and seem silly if I have a device like this lying around. Anything else I should know? Am I wasting my time with this? I also obtained a 7 foot rack, shelves, patch panels, UPS, patch panels, etc, which are going into a conveniently air conditioned closet. All constructive advice appreciated.

• Excel 2010 data validation warning (compatibility mode)

  - by Madmanguruman

  We have some legacy worksheets that were created in Excel 2003, which are used by LabVIEW-based test automation software. The current LabVIEW software can only handle the legacy .xls format, so we're forced to keep these worksheets as-is for the time being. We've migrated to Office 2010 and when working with these worksheets, I see this warning: "The following features in this workbook are not supported by earlier versions of Excel. These features may be lost or degraded when you save this workbook in the currently selected file format. Click Continue to save the workbook anyway. To keep all of your features, click Cancel and then save the file in one of the new file formats." "Significant loss of functionality" "One or more cells in this workbook contain data validation rules which refer to values on other worksheets. These data validation rules will not be saved." When I click 'Find', some cells that do indeed have validation rules are highlighted, but those rules are all on the same worksheet! We're using simple list-based validation, with some cells off to the side containing the valid values (for example, cell B4 has a List with Source "=$D$4:$E$4") This makes no sense to me whatsoever. One, the workbook was created in Excel 2003, so obviously we couldn't implement a feature that doesn't exist. Secondly, the modifications we're making don't involve changing the validation rules at all. Thirdly, the complaint that Excel is making is incorrect! All of the rules are on the same worksheet as the target. As if the story wasn't bizarre enough: I went ahead and saved the worksheet with Excel 2010. I then went to an old computer back in the lab and opened the document with Excel 2003. Guess what - the validations were untouched! My questions are: is this a legitimate bug in Excel 2010, or is this some exotic error in the legacy .xls worksheet that is confusing the heck out of Excel 2010? Has anyone else observed this issue working in compatibility mode?

• Backup software for incremental swapped-out drives?

  - by user13743

  We're using Acronis Home 11 to backup our main Windows machine at the office. We have a set of portable hard drives that we swap out each week, for redundancy. We have incremental sets ( a new diff of the entire series each night) building on each drive. However, from time to time, Acronis gets confused and sometimes makes a new full backup. This eats up a lot of drive on the disks. Also, I have to trick the Acronis script each time I swap out a drive and point it to the new incremental backup set. Finally, if a drive gets full, there's no way to partition the backup set on a drive. I found this out the hard way, and now one drive is full with one backup set. So now on the other drive, I have three folders of backup sets. When one starts to get full, I delete the oldest one and start a new set. That way one single drive never gets filled up with one single backup set. I'm looking for a backup software that can backup Windows in incremental sets, and doesn't get tripped up with swapped out drives. Is there a better solution?

• Configuration Help for Sendmail Required

  - by Vinayak Mahadevan

  Hi I need some help with respect to sendmail configuration. The basic problem is that I have some employees working from other places and they need access to their mail. So what I have done right now is whatever mails which are meant for them which are generated from within the company and collected by my internal mail server is bounced to an external mail server from where the employees access it. This is done through a email id on a different domain. This was working fine till I restricted the external mailing access for certain users using rulesets in sendmail.cf. Once I had put that in place only people who had external mailing rights could send mails to people outside the office. What I would like to know is that is there anyway where I can expose sendmail on two different ips and thereby configure everybody's email id to point to the same internal mail server using 2 different ips. one ip when inside the company and one ip outside the company. Is it possible that I have one static ip configured for both internal access and external access or is there any otherway it can be done with sendmail. Can anybody help me Sorry for the long post Regards Vinayak

• Overheating Toshiba Satellite L300

  - by ldigas

  A coleague of mine's having trouble with his new Toshiba Satellite L300 ... I tool a kook at it, and indeed it's hot as hell. I couldn't hold my hand on it for too long. He says it also has a tendency to turn itself off (WinXP 32bit running) with no forewarning. Hasn't happened to me while I was using it, but that wasn't long anyways. The first guess was it was too dirty ... problem is it's new, came out of a package a quarter of a year ago. Kept in a clean environment (office). Looks clean. No dust in sight. Second guess is that the fan wasn't working properly, cause indeed it has intervals of working, and non working. But when I listen to it, it sounds like normal usage. I took a SpeedFan measurement, and it reports temp. up to 85 Celsius ... which is definitely too high. Anyone knows what else I could do to it ? It is under warranty and it will go to the service, but I thought if there is something we can do, as to avoid carrying it there / be without it for a week ...

• Using our own certificate authority for business email encryption

  - by LumenAlbum

  I've read the available similar questions on serverfault but I haven't quite found a definite answer to the security aspect of it - hence here's my question: I'm administrator of an office working with tax data and we want to start using certificate-based eMail encryption with our clients. Considering the prices for issued certificates by VeriSign & Co I was wondering if we couldn't issue the necessary certificates with a certificate authority of our own. I realize that they do not offer the trust hierarchy that commercial certificates do but I don't see why we would need that. Most of our clients have small businesses and only 20% of them even exchange data with us via email. So if we were to issue certificates for those 20% and our employees, that would enable us to use encrypted emails. Of course they would have to trust our certificate authority and thus once receive our public root certificate. But if we would hand them out to them (or install it) personally, they'd know that it really is our certificate. Is thery a huge security risk that I am missing here? As long as nobody has access to our certificate authority server nobody should be able to interfere with security, right? And the client certificates would be generated and handed out by us, as well... Please advise me if I am making an error in judgement here and thank you in advance.

• Suggestions for accessing SQL Server from internet

  - by Ian Boyd

  i need to be able to access a customer's SQL Server, and ideally their entire LAN, remotely. They have a firewall/router, but the guy responsible for it is unwilling to open ports for SQL Server, and is unable to support PPTP forwarding. The admin did open VNC, on a non-stanrdard port, but since they have a dynamic IP it is difficult to find them all the time. In the past i have created a VPN connection that connects back to our network. But that didn't work so well, since when i need access i have to ask the computer-phobic users to double-click the icon and press Connect i did try creating a scheduled task that attempts to keep the VPN connection back to our office up at all times by running: >rasdial "vpn to me" But after a few months the VPN connection went insane, and thought it was both, and neither, connected an disconnected; and the vpn connection wouldn't work again until the server was rebooted. Can anyone think of a way where i can access the customer's LAN that doesn't involve opening ports on the router needing to know their external IP customer interaction of any kind Blah blah blah use vpn vnc protocol has known weaknesses you are unwise to lower your defenses it's not wise to expose SQL Server directly to the internet you stole that line from Empire Customer doesn't care about any of that. Customer wants things to work.

• Logmein does not work at home?

  - by Littlet-ENG

  I've been using logmein successfully for may situations and have had very good success. Our company has an Log me in Pro account. I have used this to share my desktop with customers. At work, I have had no problem with my laptop. At home, one program (solid-works) that I need to share with my customers, will not display the active screen. I spent 45 min on the phone with both the software for the cad system and logmein support with not help. I need help in narrowing down what the problem is on my computer. The support guys at Solid-works got another remote software to work, so its not the program. I can get the logmein to work at the office so its not the settings of the logmein pro account. The LMI people say its a setting on my computer.? -internet is fast enough at home -can't narrow down the problem -changed graphical settings and that didn't work. Any Suggestions?

• How do i set up a fully featured small business network?

  - by JoshReedSchramm

  This has the possibility to be a very large question but I recently acquired a few rack mount servers and the hardware necessary to run them. Unfortunately I'm a programmer with very little understanding of how to set up a good working network so I'm hoping someone on here might be able to help. What I want to do is run a domain with a series of subdomains which would all be externally accessible. The setup would live inside my home and my internet connection is your run of the mill cable model (which means a dynamic IP) I want to be able to set up a couple site, specifically: www.mycompany.com (mycompany.com with no subdomain would redirect to this) build.mycompany.com (for my continuous integration server) ruby.mycompany.com (for ruby projects) win.mycompany.com (for windows project) etc. Additionally this is still my home network so our personal machines need to be able to get on via wifi with at least the same security we have now through an out of the box router from best buy. I'm thinking i need a DNS server, DHCP server and one of those would run either no-ip or dyndns to accommodate the dynamic ip. I don't necessarily need mail but it might be helpful to have some sort of mail server i could use for testing, it doesn't need to get out to the greater internet though. So how do i set up this kinda of network? tl;dr Need to know how to set up your standard office style network in my home off my normal consumer level cable modem connection.

• Setup staging with multiple SVN

  - by Kapil Sharma

  We are a startup, setting new environments for product to be released soon. Planned server structure with planned release flow is as shown in below image It ideally have a local server (or Staging server, shown in green) in local office, without public IP address and Production Server (Red) at Amazon EC2. Both local and production server have there own SVN copy. Management here want to update production server with production SVN and without providing its access to developers (including freelancers/contract employees). So for developers, there is a Local SVN on local server. Another purpose of local SVN to keep a copy of code on local server, which is under our direct control. Although there are some technical concerns like how will code at local server will be updated from local SVN and commit on production SVN but bigger question is, is that structure correct? Major requirement remain don't provide production SVN access to developers. What are other possible options to achieve that? Another minor question, if suitable here, if above structure is correct, is it possible for a SVN checkout to get updated from one SVN (Local SVN) but commit to other (Production SVN)? If yes, How? edit An answer has been accepted but for bounty, I'm still looking for answer Is that structure correct? Its pros/Cons? Technical solution is already provided by accepted answer.

• Painfully slow login to AD bound Mac OS X Leopard machine when off home network

  - by GeeBee

  Dear all Just looking for a little help with this problem that seems to trip a lot of people up and is causing me no end of grief. I have a number of fully patched OS X Leopard machines that are bound to my AD (Server 2003). When on the home network, logging in seems swift and works as expected. When users take the machines off site, login can take 5 minutes or more. The user adds correct credentials but the desktop does not appear for a very long time. Outside the office, I have tried logging in using a local Admin account, switching off Airport and then logging in using an AD account. In this situation login is immediate again. It all seems as if Leopard is finding a suitable wireless network, spending far too long looking for the Domain before eventually giving up and using the cached credentials instead. I have read that disabling Bonjour on the machine will stop this problem (i have not yet tested) http://www.macwindows.com/leopardAD.html#111607z ...but I am reluctant to use this "Solution" as I would like to be able to use Bonjour on the local network as well as having AD-bound machines. However, is disabling Bonjour really the only answer? Is there not some time-out setting somewhere that could be amended to stop Leopard spending forever looking for home? Any help would be very gratefully received Thanks Gordon

• Remote search system for samba shares

  - by fostandy

  I have several shares residing on a samba server in a small business environment that I would like to provide search facilities for. Ideally this would be something like google desktop with some extra features (see below), but lacking this the idea is to take what I can get, or at least get an idea for what is out there. Using google desktop search as a reference model, the principle additional requirement is that it is usable from clients over the network. In addition there are some other notes (note that none of these are hard requirements) The content is always files, residing on a single server, accessible from samba shares. Standard ms office document fare Also a lot of rars and zips which it is necessary to search inside. Permissions support, allowing for user-based control to reflect current permission access in samba shares. The userbase will remain fairly static, so manual management of users is fine. majority of users will be Windows based I know there are plenty of search indexers out there: beagle and tracker seem to be the most popular. Most do not seem to offer access control and web-based/remote search does not seem to be high priority. I've also seen a recent post on the samba mailing list asking for pretty much the exact same thing. (They mention a product called IBM OmniFind Yahoo! Edition and while their initial reception seems positive, I am pretty skeptical. RHEL 4? Firefox 2? Updated much?) edit: similar question here What else is out there? Are you in a similar situation? What do you use?

• Sendmail : Mail delivery of same domain to internal or external mail server.

  - by Silkograph

  Its bit difficult to explain but very simple problem. We have internal sendmail server and hosted server. Both are set to same domain name. We have mixed mail accounts. For example we have two user in one office. [email protected] is local only [email protected] is internal plus external. Internal means we create user on local linux box where sendmail is set. External means we create user on local and hosted server. [email protected] can send mails to any internal user created on Linux box where sendmail is installed. But he can not send mail to outside domain and no mail can be sent to him as there is no account created on external hosted server. [email protected] can send mails to internal as well as all other domains through sendmail's smart_host feature, which uses hosted server's smtp. [email protected] can get all external emails internally through Fetchmail on linux box. Now we have third user [email protected] who will be always outstation and can use external server only. So I can not create account on local linux box for [email protected] because his mail will get delivered locally only. I don't want to create alias and send his mails to gmail or yahoo's account. I want to send emails to his external account from any internal user. How this can be done? Thanks in advance.

• Troubleshoot dropped wireless connections

  - by Jack

  I was recently hired in the IT department of a small company (~180 users) and one of the issues that people have been complaining about is having their wi-fi connections drop during meetings. The company is using an HP ProCurve Wireless LAN with 10 APs and a controller unit located in the server room. I don't have any experience troubleshooting WLAN in a multi-AP environment, so I'm trying to at least gather information using free or cheap tools. I did a basic site survey using the free version of Ekahau HeatMapper and discovered the following in one of the conference rooms that has been a problem. The program picked up three access points (plus a bunch of others with much lower signals that were out of range): AP 1: SSID: "Unknown SSID" - Signal strength: -48 dBm - -40 dBm. Channel: 2 AP 2: SSID "CompanyMain" - Signal strength: -35 dBm or greater. Channel: 2. Security: WEP (This is the main SSID for the company's WLAN.) AP 3: SSID: "CompanyGuest" - Signal strength: -40 dBm - -35 dBm. Channel: 2. Security: WPA2 (This SSID is the company's "guest" WLAN, which was setup to allow Internet access, but prevent network access.) Is there anything that you see that is clearly a problem from the above? I'm assuming that the unknown SSID might be a big problem, and that it is an AP from a neighboring office that is causing interference. Does that seem likely? Also, regarding channel, should we try changing the channels of our APs to avoid interference with that unknown SSID? (Since everything seems to be on Channel 2?) Should our APs be on different channels? In other words, should the CompanyMain and CompanyGuest APs be on different channels? Finally, any recommendations for free/cheap tools to help me figure this out, and/or a good methodology to follow? Thanks in advance for any help. Jack

• How to choose which network connection provides the default gateway in Windows XP

  - by Cathy

  I have a laptop with an integrated NIC and a WiFi connection. Both the wired and wireless networks I am using can access the Internet. Win XP is routing all traffic through the wireless network. I want to force it to route everything through the wired network when it is available (i.e. when I am sitting at my desk with the laptop docked) and through the wireless when that is the only option (i.e. when I have undocked my laptop and carried it to a conference room, or if I am out of the office working on a different WiFi network). The wireless connection cannot be established until after I am logged into Windows, so it's always the second network to become available to the OS. I have manually overridden the metric values in the TCP/IP configurations so that the NIC has metric 10 and the WiFi has metric 20. However, Windows is still picking the WiFi adapter's address as the Default Gateway, so this isn't helping. If I manually disable and re-enable the WiFi adapter, then it will switch the default gateway to the wired network and stay that way until I shutdown Windows. How can I tell Windows XP not to replace the default gateway when the WiFi connection is first enabled?

• Cable management techniques

  - by cornjuliox

  How do you manage the giant jungle of cables behind your PC? When you have 2 or more PCs next to each other, you wind up with this giant mess cables that's a pain in the neck to clean especially when both computers are running 24/7 and any fidgeting with the cables is likely to cause data loss and/or angry users. So far I've tried masking tape, cable ties and plain old string but none have been very effective. The masking tape kept the cables in place, but over time they ended up leaving this awful sticky residue on the sides of the cables that just won't come off gets all over your fingers and is horrible horrible horrible. I have nightmares about that stuff. We used cable ties and 'folded' up some of the longer cables so that they weren't any longer than they needed to be, but this meant that the position of some of our devices like the keyboard and the mouse were essentially 'fixed' until we removed the ties. The string didn't work much differently and required that we tie them properly or risk it coming loose. I would switch to a wireless keyboard and mouse, but I don't want to have to deal with the added expense of batteries, even the rechargable ones. Plus I don't want them to die on me at a crucial moment (happened to me once while playing Firearms _<). I know that there are people out there with home/office networks a thousand times more convoluted than mine, so
