• Joining two routers together, but I have no access to the second router, although I know it's IP address and Gateway

  - by JohnnyVegas

  I have temporarily moved into a rented apartment for 4 months, which has wireless. The trouble I am having is that the access points here are wifi only and no RJ45 and I need to use RJ45 to connect some equipment that I am working with. I have purchased an RT-N66U and installed Tomato (shibby ver. 1.28) and successfully replaced the existing access point, but now I want to enable the access point that I have replaced as it links wirelessly to 3 others. Can I plug in a cable from the access point to my RT-N66U and get it to access the internet via my router? I have no access to the existing wireless access point, and don't want to reset it as it's not mine. There is another router situated in the roof somewhere which I also have no access to, but it's supplying my RT-N66U internet and I most definitely have a double-nat, which although isn't the best way of doing things I am limited with what I can do. Any suggestions on routing tables, vlans etc would be helpful, but I have no experience in these fields before - but I know the tomato firmware can cater for this. My router is set to IP 10.0.1.1 and dhcp is 10.0.1.100-200 The wireless access point address was 192.168.1.2 but this was assigned by the router in the roof which has the address 192.168.1.1. There is a cable from this router going to a wall socket which I now have my RT-N66u attached to via the WAN port. I understand it's scruffy and it isn't the way to do things but I have tried to ask for the admin details but as the wireless network is looked after by a third party and nobody knows their details I am stuck with this dilemma. I could buy three wireless access points and replace the existing but this isn't what I want to do, and although I have installed plenty of DD-WRT wireless repeater bridges they simply don't work here for some unknown reason. The phone line here is very noisy too and I don't have the rights to install ADSL in a building that isn't mine, and 3G coverage isn't good enough either. Thanks for your time

• Configuring apache and php to handle many connections

  - by Marc

  My preliminary setup is like this. Two QuadCore 8GB servers running debian 6, with php and apache, One QuadCore 16GB server running debian 6, with mysql My plan is to have one 8Gb server to act as a proxy server, using vertx java to handle connections. I will let vertx use HttpClient to send web requests to the second 8GB server. This would have apache installed and use php to deliver any information that it gets from the mysql server on the third, 16GB server. The main reason I want this setup is to have things separated, so the "proxy" will be the only way to access the system, as the other two server will only be reachable from the local network. I can have the vertx proxy handle 5000+ concurrent connections, but, I don't know how to configure apache to handle all the requests coming from the proxy. Php will connect over mysqli with persistent connection pool of 500-800 connections, the mysql server seems not to have any issues on this part. In previous projects, the apache part was always causing issues, no matter how I set it up. I might not fully understand how to setup apache, since normally apache should handle many concurrent connections, but it does seem to now.

• SquidGuard and Active Directory: how to deal with multiple groups?

  - by Massimo

  I'm setting up SquidGuard (1.4) to validate users against an Active Directory domain and apply ACLs based on group membership; this is an example of my squidGuard.conf: src AD_Group_A { ldapusersearch ldap://my.dc.name/dc=domain,dc=com?sAMAccountName?sub?(&(sAMAccountName=%s)(memberOf=cn=Group_A%2cdc=domain%2cdc=com)) } src AD_Group_B { ldapusersearch ldap://my.dc.name/dc=domain,dc=com?sAMAccountName?sub?(&(sAMAccountName=%s)(memberOf=cn=Group_B%2cdc=domain%2cdc=com)) } dest dest_a { domainlist dest_a/domains urllist dest_b/urls log dest_a.log } dest dest_b { domainlist dest_b/domains urllist dest_b/urls log dest_b.log } acl { AD_Group_A { pass dest_a !dest_b all redirect http://some.url } AD_Group_B { pass !dest_a dest_b all redirect http://some.url } default { pass !dest_a !dest_b all redirect http://some.url } } All works fine if an user is member of Group_A OR Group_B. But if an user is member of BOTH groups, only the first source rule is evaluated, thus applying only the first ACL. I understand this is due to how source rule matching works in SquidGuard (if one rule matches, evaluation stops there and then the related ACL is applied); so I tried this, too: src AD_Group_A_B { ldapusersearch ldap://my.dc.name/dc=domain,dc=com?sAMAccountName?sub?(&(sAMAccountName=%s)(memberOf=cn=Group_A%2cdc=domain%2cdc=com)) ldapusersearch ldap://my.dc.name/dc=domain,dc=com?sAMAccountName?sub?(&(sAMAccountName=%s)(memberOf=cn=Group_B%2cdc=domain%2cdc=com)) } acl { AD_Group_A_B { pass dest_a dest_b all redirect http://some.url } [...] } But this doesn't work, too: if an user is member of either one of those groups, the whole source rule is matched anyway, so he can reach both destinations (which is of course not what I want). The only solution I found so far is creating a THIRD group in AD, and assign a source rule and an ACL to it; but this setup grows exponentially with more than two or three destination sets. Is there any way to handle this better?

• Apache+PHP on Windows Server 2008

  - by Álvaro G. Vicario

  I've installed Apache/2.2 and PHP/5.3 lots of times under Windows XP, Windows Vista and Windows Server 2003. The official *.msi installers work fine and configure everything. Now I need to install them into a Windows Server 2008 R2 Standard 64-bit box and I'm facing nothing but problems: There are no official 64 bit binaries for Apache and no binaries at all for PHP (official or third-party). It's alright, I'll do with good 32 bits, but it's kind of surprising. Official documentation is vague, generic and completely unaware of UAC or any recent Windows security feature. The PHP installer is unable to configure mod_php and the Apache installer is unable to configure... well, Apache. After three hours I've finally reached the point where I'm installing everything in the root folder and assigning full control access to all users in all files and directories and all I've got is a PHP-less Apache server that's able to serve static pages. So I guess it's time to stop and think. My question is: Has anyone installed an Apache+PHP production server under Windows Server 2008 in a serious, secure and reliable way and documented the whole process? Or should I just find a bundle like XAMPP and the like that requires no installation? === EDIT === I've installed Xampp Lite 1.7.3 and everything was working in 5 minutes. I'd still like to find some documentation about installing the original packages: XAMPP installs tons of stuff I don't need and offers no tool to enable and disable PHP extensions.

• Sort order in Windows Explorer

  - by Haim H.

  The behaviour described below occurs on Windows-7 systems and on Windows XP. We operate in a dual-language environment - English and Hebrew. When in Windows Explorer we sort files by name, the order in which they are listed is not what we would expect. Here is a list of file names as sorted by Windows Explorer (all of the files have a .pdf suffix): 1G110033H-PP 19C050G-PP-ORB 19C050H-PPRM 19C100H-PPRM 19C-MBPS-PP 19C-MBPS-PP-1 29AAC050-PP 29AAC100-PP 29AAC100-PPUL 29B004064-PP 101AC050-PP 101AC100-PP 101B100-PPE 1091003G-PPFSUL 10108033G-PPSA 10125033H-PPM It looks to me that first the items are sorted according to the position of the first alphabetic character in the name, and then, within those groups, they are sorted in "normal" alpha-numeric order. That is, all the files with an alpha character in the first position are on top of the list, followed by those with the first alpha character in the second position, followed by those with the first alpha character in the third position, and so on. An alternate way of looking at this is that, in a file name composed of numbers and letters, the sort treats the first group of numbers in the name as the major sort node, with the rest of the name being the secondary sort node. Now that I understand the sequencing logic, it's not a big problem, but I was wondering why this happens?

• Hyper-V Guests Dying

  - by Jon Rauschenberger

  I just hit my THIRD instance of a Hyper-V guest machine dying with the exact same behavior. In all three instances we are hosting WS2008 guests on a WS2008 host. AFter a config change, we reboot the guest and the guest OS comes up but in a very cripled state. Specifically, we are able to log into the guest, but can't launch any apps and the guest never comes active on the network. I opened a support ticket with MS the second time this happened and they focused in on the DCOM subsystem not coming up...best explanation they could provide was that permissions on key system files got corrupted. I eventually gave up on the ticket after close to 10 hours on the phone trying different things that were going no where. What really concerns me is that we have now seen the exact same thing happen to a guest hosted on a completly differet host machine. There is zero hardware overlap between the two. Has anyone seen this before?? It's really odd behavior, but it also seems like there's a pattern here that's concerning me. Thanks, jon

• Windows roaming profile when creating a new Windows profile

  - by molecule

  Hi all, When a particular user is having a lot of problems with Windows XP e.g. applications crashing, unresponsive applications (which used to work), and as a general troubleshooting practice for a domain user, I normally rename that user's old profile and get him/her to logon to create a "fresh" profile (on the same PC). More often than not, this will solve the problem albeit some reconfiguration i.e. Outlook, Excel add-ins etc. As I took over the systems admin role from another administrator, I would like to know what is the easiest way to find out (either through a third party or some Windows administrative tool) what settings are carried over if the profile is a Roaming Profile. I tested creating a new user profile for one of my users and it seems basic Outlook settings such as the user's mailbox and PSTs are carried over automatically when I create a new user profile. I suspect this is done through a batch file loaded as part of the login script. However, my knowledge of scripting is limited and I don't want any corruptions to be carried over to the new profile. Can someone share their experiences on this? Thanks in advance.

• Time not propagating to machines on Windows domain

  - by rbeier

  We have a two-domain Active Directory forest: ourcompany.com at the root, and prod.ourcompany.com for production servers. Time is propagating properly through the root domain, but servers in the child domain are unable to sync via NTP. So the time on these servers is starting to drift, since they're relying only on the hardware clock. WHen I type "net time" on one of the production servers, I get the following error: Could not locate a time-server. More help is available by typing NET HELPMSG 3912. When I type "w32tm /resync", i get the following: Sending resync command to local computer The computer did not resync because no time data was available. "w32tm /query /source" shows the following: Free-running System Clock We have three domain controllers in the prod.ourcompany.com subdomain (overkill, but the result of a migration - we haven't gotten rid of one of the old ones yet.) To complicate matters, the domain controllers are all virtualized, running on two different physical hosts. But the time on the domain controllers themselves is accurate - the servers that aren't DCs are the ones having problems. Two of the DCs are running Server 2003, including the PDC emulator. The third DC is running Server 2008. (I could move the PDC emulator role to the 2008 machine if that would help.) The non-DC servers are all running Server 2008. All other Active Directory functionality works fine in the production domain - we're only seeing problems with NTP. I can manually sync each machine to the time source (the PDC emulator) by doing the following: net time \\dc1.prod.ourcompany.com /set /y But this is just a one-off, and it doesn't cause automated time syncing to start working. I guess I could create a scheduled task which runs the above command periodically, but I'm hoping there's a better way. Does anyone have any ideas as to why this isn't working, and what we can do to fix it? Thanks for your help, Richard

• Troubleshooting wireless connection problem / site survey?

  - by johnnyb10

  I just started in the IT department of a small company (200 users) and it's clear that one of the main problems that is driving everyone crazy is the spotty nature of the wireless connectivity throughout the office, particularly in certain conference rooms. This is a huge problem because the connection often drops during important presentations to clients. I was hired to help ease the load on the existing IT admin, who has done a great job, but is overloaded with many other tasks to deal with. So I would like to try to help out with this wireless issue. I am looking for advice on the best way to solve this problem--a realistic troubleshooting methodology that does not require me to spend any money. So far, I've experimented with Ekahau Heat Mapper, which is free and helps create a site survey. But I'm not exactly sure what I'm looking for or if there are other programs/tools/methods I should try as well. Any advice would be greatly appreciated. [Some background: The wireless setup consists of an HP ProCurve Mobility MSM (710?) controller that controls 10 access points throughout the building. There are three virtual wireless networks configured on the controller: one seems to be a default that cannot be changed, one is for internal employees and authenticates via Active Directory, and the third is a guest network for visitors. When I use HeatMapper, these show up as three different SSIDs, with different MAC addresses, all on the same channel. At first I thought maybe this would cause interference, but this seems to be the way the controller works;apparently, it automatically configures the channels to avoid interference from the other APs on the network.]

• How to wire 20 computers and 20 phones and 1 server into LAN?

  - by John Smith

  I have currently 3 switches Two Netgear JFS524 with 24 slots, One Belkin with 16 slots. Server DSL Internet Router. Main question is how to connect switches together, two Netgear's are next to each other, yet one is about 100 feet away and holds about 5 computer and 5 phones. If i connect them with only 1 wire will that limit bandwidth? e.g. all 23 computers will be limited to speed of one CAT5e cable? If i connect switches with 2 cables will this give speed boost? What's the ideal scenario should i just move the third switch next to other two? Will the speed of computer connected to white switch be same as computer connected to top switch? Will moving white switch right next top switch and having 16 wires comming 100 feet instead of 1 wire comming 100 feet make it faster? EDIT 1: I actually have NETGEAR ProSafe GS105 Gigabit switch its only has 4 ports in it though, you think i can have use of it in current setup? Like connect all 3 switches and server into it and keep internet router and phone server on one of the slower switches EDIT 2: Everyone mention gigabit switches, but will they do any difference with 10/100 network cards? I then have to use gigabit cards in every computer too? I could in server perhaps, but users will be 10/100

• 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.

• Files not being copied to AFP volume when copying through the Finder

  - by cefstat

  I am trying to copy files from my Macbook's hard disk to my NAS. The latter is a ReadyNAS Duo and is mounted as an AFP volume. The files are about 5MB each and I copy them by selecting in a Finder window all the files that I need and then dropping them onto the destination directory. Almost always some of the files do not get copied to the NAS. For example, if I select 200 files and then start the copying, everything looks at the beginning normal (while the copying takes place the Finder window for the destination directory is updated to show 200 files while it was empty before), but after the copying ends the destination directory shows less than 200 files (let's say 190). If I copy again the same 200 files to the NAS, without replacing already copied files, the remaining 10 files are usually copied correctly. In a few cases, I have to repeat the process a third time. Notice that the Finder does not give any warning that some of the files have not been copied at any stage. I am wondering if this a known problem with AFP and the Finder and/or if there is something that I can do to solve this problem.

• 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?

• Options for synchronizing Palm Desktop calendars

  - by Al Everett

  My wife and I each have Palm Centro phones and very full calendars. We've been using Palm products for years and are happy with them and are not looking to switch (and don't have the budget for it even if we wanted to). What is a viable way we can synchronize our calendars? Back when we had Palm Z22s we used AirSet. It worked great in synchronizing our desktop calendars. Unfortunately, their sync software does not support Palm Desktop v6 and there is nothing in the pipeline to support it. (The third party vendor is apparently not interested in updating for the newer Palm desktop.) I would love to be able to get back to having each other's appointments appear on the other's calendar. What can we do? Some limitations: A data plan is not an option (so this precludes over-the-air synchronization options) No Microsoft Outlook Edit: Syncing my Palm to my Palm Desktop is not the issue. Being able to sync, in some way, the Palm calendar databases of my wife's and my calendars is what's desired.

• Computer loses all installed programs and appears to return OS-only state

  - by Jake

  This is a story regarding 3 laptops of different brand and models. On separate occassions, I configured each of these Windows 7 / Vista computers with the necessary configuration and applications (which are supposedly the same actually), e.g. join office domain, same windows updates, microft office etc. These machinese were configure in our office in Singapore, and then they were taken to India for use. Someday in India, when booting up the laptop, all went fine except when it reach the log in screen, it was no longer possible to login with domain credentials. Logging into the laptop local admin account will lead to discover that the machine has returned to "OS-only state". All the configurations and applications were gone. The actual user profiles are still in the C: drive so files can still be retrieved, but under Control Panel Uninstall Programs it is evident that at least the registry is corrupted. The above scenario happen to the first 2 laptops. For the third, the system reports "Operating System Not Found" on boot up. I cannot think of any reason except to suspect a power fluctuation issue. Question is, will a power issue create this behaviour? What else can cause this issue?

• How do I apply multiple subnets to a server with one NIC?

  - by Cosban

  I am trying to route multiple IPs through one physical NIC on my dedicated server for use with Proxmox KVM VMs. I have a dedicated server which is currently running Debian 4.4.5-8 with 3 available ip addresses for use, which will be displayed as 176.xxx.xxx.196 (main), 176.xxx.xxx.198 (on same subnet as main) and 5.xxx.xxx.166 (different subnet). I am currently trying to route the third IP address with the dedi for use with a vps that I have set up using proxmox v2.x but am having a really, really hard time doing so. Virtual interfaces binding the additional IP addresses work as expected, ruling out external routing problems. The provider has given the following information for the IP addresses on the main subnet: gateway: 176.xxx.xxx.193 netmask: 255.255.255.224 broadcast: 176.xxx.xxx.223 As well as the following information for the IP address on the second subnet: gateway: 5.xxx.xxx.161 netmask: 255.255.255.248 broadcast: 5.xxx.xxx.167 Everything I've tried with /etc/network/interfaces has either not worked, or has rendered the network completely useless. This is the current state of the file, which has the secondary IP address working on the same subnet as well as IPv6 working, but not the second subnet. # Nativen IPv6 Schnittstelle iface eth0 inet6 manual # Bridge IPv4 Schnittstelle (176.xxx.xxx.193/27) auto vmbr0 iface vmbr0 inet static address 176.xxx.xxx.196 netmask 255.255.255.224 gateway 176.xxx.xxx.193 broadcast 176.xxx.xxx.223 bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0 post-up ip addr add 176.xxx.xxx.198/27 dev vmbr0 auto vmbr1 iface vmbr1 inet static address 5.xxx.xxx.166 netmask 255.255.255.248 gateway 5.xxx.xxx.161 broadcast 5.xxx.xxx.167 bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0 post-up ip addr add 5.xxx.xxx.166/27 dev vmbr1 # Bridge IPv6 Schnittstelle (Reichweite: xxxx:xxxx:xxxx:xxxx:xxxx:xxxx::/64) iface vmbr0 inet6 static address xxxx:xxxx:xxxx:xxxx:xxxx:xxxx netmask 64 up ip -6 route add xxxx:xxxx:xxxx:xxxx:xxxx:xxxx dev vmbr0 down ip -6 route del xxxx:xxxx:xxxx:xxxx:xxxx:xxxx dev vmbr0 up ip -6 route add default via xxxx:xxxx:xxxx:xxxx:xxxx:xxxx dev vmbr0 down ip -6 route del default via xxxx:xxxx:xxxx:xxxx:xxxx:xxxx dev vmbr0

• Calendar sharing between unrelated Domains

  - by vlannoob

  I have a 'request' from one of the 'big guys' that has me scratching my head a bit. He is one of our Executives that also is a board member of several other organistations, so he floats around between 4 different unrelated companies, each with their own domains, Exchange setup etc. He has domain accounts in each organisation. He has an iPad with multiple Exchange accounts so he can see all his calendars which works Ok for him - Apple calendaring bugs/flaws aside. What he wants is the ability for 'reception staff' at each organisation to 'see' all his calendars as they are booking things for him in their respective organisations calendars without it conflicting with bookings made in his calendars by other organisations......you with me?? So for example: Company A books a meeting into his Comapny A calendar at 9am Monday and Company B books him a meeting in his Company B Calendar at 9:15am Monday on the other side of town and of course Company C has him booked in all day Monday on their Company C calendar. He gets all those on his iPad but he would like either a 'global' calendar all can see and book into or the ability for receptionists at Company's A,B and C to see all the Calendars to avoid these kind of conflicts. I told him to 'go away' straight off the bat, I don't control anything to do with the other companies or know their infrastructure. And quite frankly I don't want any part of it...but he's whining and he's high enough up the food chain that I can't ignore him forever. I'm open to suggestions. Is there any third party software/services that can facilitiate this kind of setup? I really don't want to be creating users in my AD structure to people not ion our organisation so they can get access to his calendar and I am sure there sysadmins feel the same. As usual - any advice is greatly appreciated ;)

• When to use Truecrypt, and when not to?

  - by tm77

  I have about 30 (this number will most likely grow over the next few years to 50 or more) unencrypted laptops that I have been tasked to encrypt (entire drive). These machines will be used off site regularly by my users. These machines are running Windows 7 and XP (about 50/50), but more Windows 7 every month. I have experience with Truecrypt, and have had no issues. It appears to be THE solution for a free solution. My concern with Truecrypt is that my users will have 2 passswords needed to login to their machines. Also, I need to choose to either have 1 password for my organization, or carefully document each machine's password (management nightmare). In my mind, choosing between a managed and a free encryption solution is primarily based on the NUMBER of machines that will be encrypted and supported. Two questions: From a management standpoint, what is the tipping point of users where a managed solution would pay for itself over Truecrypt? What are some good third party solutions? (I will consider Bitlocker, but the price to upgrade Windows 7 licenses is a turn-off) I would love to hear from some admins with experience in supporting encrypted machines in a corporate environment. Many thanks in advance!

• emacs, writing custom commands which use term-mode

  - by valya

  Hello, I'm using Emacs and M-x term for a terminal. Since my typical workflow looks like this: edit some code C-x C-o to the terminal buffer (or C-x b term[Enter] or something) press Up key to use the last command press Enter to run it C-x C-o to go back I want to bind all of these (except the first step... maybe) to one command, I believe Emacs is awesome enough to do that :-) So, a command must: go to the buffer with terminal (maybe it shouldn't change any windows at all, maybe it should split the window vertially (if it weren't split already) and use the right sid) run a last command what've been run there go back to the last buffer/part of the screen Thank you! I'm not really used to the Emacs scripting system, and I hope someone will help me and someone else will be able to use the answer to improve his workflow, since I believe this is a pretty common one Examples of commands: python manage.py test python manage.py test stats python solve.py # for project-euler puzzles :-) the first and the second runs over a ssh (in a terminal) sometimes (I like developing with vagrant) I understand that it's easy to bind the first and the third ones, but the second changes too often - I'd just like to "run last command"

• HTTP Upload Problems

  - by jfoster

  We are running a marketplace on ColdFusion8 and IIS with a widely geographically distributed user base and have been receiving complaints of issues with some HTTP uploads. Most of the complaints are coming from geographically distant locations from our main datacenter on the US east coast. I've attempted to upload the same 70MB file from a US West coast test server to both our main site and a backup running the same code on a different network route and I saw the same issues fairly consistently in both places, so I've ruled out the code, route, and internal network errors. I've also tested uploads using both the native cf upload tag and a third party tool called SaFileUp. I saw the same issues with both upload tools, so I also don't think this is necessarily a ColdFusion problem. I don't have any problems uploading the test file from the East coast to other east coast servers, so I'm beginning to think that the distance between our users and our equipment is a factor. I've also found that smaller files are more likely to succeed than large ones (< 10MB) I tried the test upload with both IE and FF and did notice a difference in the way that the browsers seemed to handle packet errors. IE seemed to have a tough time continuing an upload after dropped / bad packets, whereas FF seemed to have the ability to gracefully resume an upload after experiencing packet problems. Has anyone experienced similar issues? Is there anything we can do on our side to make uploads more forgiving to packet loss or resumable after an error? A different upload tool etc… Do we need upload servers in more than one location to shorten the network routes between clients and servers? Does anyone think that switching uploads to SSL will help (no layer7 packet sniffing may lead to a smoother upload). Thanks.

• How to rewrite these URLs?

  - by Evik James

  I am brand new to URL rewriting. I am using an Apache rewriting module on IIS 7.5 (I think). Either way, I am able to do rewrites successfully, but am having trouble on a few key things. I want this pretty url to rewrite to the this ugly url: mydomain.com/bike/1234 (pretty) mydomain.com/index.cfm?Section=Bike&BikeID=1234 (ugly) This works great with this rule: RewriteRule ^bike/([0-9]+)$ /index.cfm?Section=Bike&BikeID$1 Issue #1 I want to be able to add a description and have it go to exactly the same place, so that the useful info is completely ignored by my application. mydomain.com/bike/1234/a-really-great-bike (pretty and useful) mydomain.com/index.cfm?Section=Bike&BikeID=1234 Issue #2 I need to be able to add a second or third parameter and value to the url to get extra info for the db, like this: mydomain.com/bike/1234/5678 mydomain.com/index.cfm?Section=Bike&BikeID=1234&FeatureID=5678 This works using this rule: RewriteRule ^bike/([0-9]+)/([0-9]+)$ /index.cfm?Section=Bike&BikeID=$1&FeatureID=$2 Again, I need to add some extra info, like in the first example: mydomain.com/bike/1234/5678/a-really-great-bike (pretty and useful) mydomain.com/index.cfm?Section=Bike&BikeID=1234&FeatureID=5678 So, how can I combine these rules so that I can have one or two or three parameters and any of the "useful words" are completely ignored?

• Is Windows Server 2008R2 NAP solution for NAC (endpoint security) valuable enough to be worth the hassles?

  - by Warren P

  I'm learning about Windows Server 2008 R2's NAP features. I understand what network access control (NAC) is and what role NAP plays in that, but I would like to know what limitations and problems it has, that people wish they knew before they rolled it out. Secondly, I'd like to know if anyone has had success rolling it out in a mid-size (multi-city corporate network with around 15 servers, 200 desktops) environment with most (99%) Windows XP SP3 and newer Windows clients (Vista, and Win7). Did it work with your anti-virus? (I'm guessing NAP works well with the big name anti-virus products, but we're using Trend micro.). Let's assume that the servers are all Windows Server 2008 R2. Our VPNs are cisco stuff, and have their own NAC features. Has NAP actually benefitted your organization, and was it wise to roll it out, or is it yet another in the long list of things that Windows Server 2008 R2 does, but that if you do move your servers up to it, you're probably not going to want to use. In what particular ways might the built-in NAP solution be the best one, and in what particular ways might no solution at all (the status quo pre-NAP) or a third-party endpoint security or NAC solution be considered a better fit? I found an article where a panel of security experts in 2007 say NAC is maybe "not worth it". Are things better now in 2010 with Win Server 2008 R2?

• Graphics and USB devices freezing soon after OS loads

  - by Andrew

  I run Ubuntu/Windows dual boot. Last night I started the upgrade to Ubuntu 12.04, and my computer has not worked since in either Windows or Ubuntu. Here's what I got when I rebooted after the upgrade, and continue to get every time I boot: Gets to GRUB screen OK. Choose Ubuntu - black screen or crazy purple lines. At first I assumed something went wrong with the upgrade (often happens). Choose Windows - works fine, I log in, but soon after that the graphics freeze (sometimes with purple artifacts). The keyboard and mouse (both USB) also lose power at the same instant, and none of the USB ports have power to them. This happens sooner or later every time I boot. Update: the HDD also appears to lose power at the same point. I have tried a live CD, but my computer refuses to boot any CD even after disabling all other boot options in the BIOS. I have disconnected everything except keyboard, mouse, graphics card with one monitor, one RAM sick and HDD; no change. I also took the little battery out to reset CMOS. I am pretty sure no matter how wrong the Ubuntu upgrade went, it wouldn't cause the above symptoms in Windows. So the only explanation I can think of is that a hardware failure occurred at the same time. Some possible causes of this I can think of are: A couple of days before this, I added a third screen (which worked fine). About a week before, my house lost power in a storm (no ill effects over the past few days though). What can I do, other than buy a new motherboard/CPU and hope it works? Unfortunately I don't have another box to swap parts into to test at the moment.

• How to change controller numbering/enumeration in Solaris 10?

  - by Jim

  After moving a Solaris 10 server to a new machine, the rpool disk is now c1t0d0. We have some third party applications hard coded for c0t0d0. How can I change the controller enumeration on this machine? There is no longer a c0. I've tried rebuilding the /etc/path_to_inst, but the instance numbers don't seem to match up with the controller numbers. Also, it's not clear if i86pc platforms use this file. I've tried devfsadm -C to clear the dangling links, but I'm not sure how to cause devfsadm to start numbering from 0 again (or force certain devices in the tree to a specific controller number). Next I am going to try to create the symlinks manually in /dev/dsk and rdsk to point to the correct /devices. I feel like I am going way off path here. Any suggestions? Thanks Update: This is on virtual ESXi hardware with an additional pass-through HBA. There is no controller 0 on the machine, that is for sure. devfsadm -C cleans up all the c0 device symlinks but keeps the already linked controllers at their current ids.
