• Timestamp Updating Constantly on /dev/null

  - by motorleague

  I've been working on a problem with a /dev/null file on an AIX system (just for background it looks as though it was inadvertently deleted and recreated as a normal file by somebody), but in trying to determine what caused the problem, I noticed that the timestamp on it seems to update every minute. I've observed this on several AIX servers at my workplace. At present I can't entirely rule out this be something specific to the Application being used at my workplace, so I compared with CentOS and Debian based computers at home last night. The CentOS box, which runs 24 hours, had a mod time on /dev/null of around 4 days ago (during which time it was essentially just being used as a web browser and multimedia player, although it would have had active but essentially unused Apache, MySQL and VMM processes running in the background). The timestamp on /dev/null on the Debian machine, which was a just booted laptop, pretty much reflected the boot time, but I tested redirecting STDIN from, and STDOUT to it, and the modification time was unchanged (I'm not sure 100% sure if directing data to /dev/null constitutes "writing to it" in the way it would a normal file). So my question is essentially, could anybody please offer any advice with regards to what circumstances (permissions changes etc.. aside) might cause the timestamp on /dev/null to update? Thanks very much for any suggestions. Alex.

• How can I optimize my ajax calls to deliver at 60ms.

  - by Quintin Par

  I am building an autocomplete functionality for my site and the Google instant results are my benchmark. When I look at Google, the 50-60 ms response time baffle me. They look insane. In comparison here’s how mine looks like. To give you an idea my results are cached on the load balancer and served from a machine that has httpd slowstart and initcwnd fixed. My site is also behind cloudflare From a server side perspective I don’t think I can do anything more. Can someone help me take this 500 ms response time to 60ms? What more should I be doing to achieve Google level performance? Edit: People, you seemed to be angry that I did a comparison to Google and the question is very generic. Sorry about that. To rephrase: How can I bring down response time from 500 ms to 60 ms provided my server response time is just a fraction of ms. Assume the results are served from Nginx - Varnish with a cache hit. Here are some answers I would like to answer myself assume the response sizes remained more or less the same. Ensure results are http compressed Ensure SPDY if you are on https Ensure you have initcwnd set to 10 and disable slow start on linux machines. Etc. I don’t think I’ll end up with 60 ms at Google level but your collective expertise can help easily shave off a 100 ms and that’s a big win.

• iptables rules to allow HTTP traffic to one domain only

  - by Zenet

  I need to configure my machine as to allow HTTP traffic to/from serverfault.com only. All other websites, services ports are not accessible. I came up with these iptables rules: #drop everything iptables -P INPUT DROP iptables -P OUTPUT DROP #Now, allow connection to website serverfault.com on port 80 iptables -A OUTPUT -p tcp -d serverfault.com --dport 80 -j ACCEPT iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT #allow loopback iptables -I INPUT 1 -i lo -j ACCEPT It doesn't work quite well: After I drop everything, and move on to rule 3: iptables -A OUTPUT -p tcp -d serverfault.com --dport 80 -j ACCEPT I get this error: iptables v1.4.4: host/network `serverfault.com' not found Try `iptables -h' or 'iptables --help' for more information. Do you think it is related to DNS? Should I allow it as well? Or should I just put IP addresses in the rules? Do you think what I'm trying to do could be achieved with simpler rules? How? I would appreciate any help or hints on this. Thanks a lot!

• iptables rules for DNS/Transparent proxy with ip exceptions

  - by SlimSCSI

  I am running a router (A Netgear WNDR3700 if that matters) with dd-wrt. For content filtering I am using OpenDNS. I wanted to make sure a user could not bypass OpenDNS by putting in their own name servers, so I have a rule to catch all DNS traffic. iptables -t nat -A PREROUTING -i br0 -p all --dport 53 -j DNAT --to $LAN_IP I did have one computer on the network I wanted to allow past OpenDNS filters. On that machine I manually set the name servers, and created another rule to allow it to pass iptables -t nat -I PREROUTING -i br0 -s 192.168.1.2 -j ACCEPT This worked well. Today, I installed a transparent proxy (squid) on the router and added these rules: iptables -t nat -A PREROUTING -i br0 -s $LAN_NET -d $LAN_NET -p tcp --dport 80 -j ACCEPT iptables -t nat -A PREROUTING -i br0 -s ! $PROXY_IP -p tcp --dport 80 -j DNAT --to $PROXY_IP:$PROXY_PORT iptables -t nat -I POSTROUTING -o br0 -s $LAN_NET -d $PROXY_IP -p tcp -j SNAT --to $LAN_IP iptables -I FORWARD -i br0 -o br0 -s $LAN_NET -d $PROXY_IP -p tcp --dport $PROXY_PORT -j ACCEPT This also works, however the 192.168.1.2 address does not get routed through squid. How can I have 192.168.1.2 (and maybe others in the future) by-pass the port 53 rules, but not the port 80 rules?

• Best way to restrict access to a folder in Dropbox

  - by Joe S

  I currently run a business with around 10 staff members and we currently use Dropbox Pro 100GB to share all of our files. It works very well and is inexpensive, however, I am taking on a number of new staff and would like to move the more sensitive documents into their own, protected folder. Currently, we all share one Dropbox account, I am aware that Dropbox for teams supports this, but it is far too expensive for us as a small company. I have researched a number of solutions: 1) Set up a new standard Dropbox account just for use by management, which will contain all of the sensitive documents, and join the shared folder of the rest of my team to access the rest of the documents. As i understand it, this is not possible with a free account, as any dropbox shared folder added to your account will use up your quota 2) Set up some sort of TrueCrypt container, and install TrueCrypt on each trusted staff member's machine, and store the documents inside that. Would this be difficult to use? I'd imagine the sync-ing would not work so well as the disk would technically be mounted at the time of use and any changes would be a change to the actual container rather than individual files. I was just wondering if anyone knows a way to do this without the drawbacks outlined above? Thanks!

• Windows 7 Laptop Randomly Sleeping

  - by Josh Arenberg

  I'm running Windows 7 64-bit on a Lenovo laptop, and I have a problem wherein after I've put it to 'sleep' once, it will seemingly without any reason or warning go back to sleep every 10 to 15 minutes after that. Each time it wakes back up just fine, and you can happily continue on. However, 10 or 15 minutes later, it just drops out into sleep mode. I don't see any errors in the system logs. I don't think it's related to heat ( since it's not rebooting ). When I check the system event log, I can see where the machine goes to sleep, but it simply says "reason: application API", and doesn't indicate which app ( brilliant ). I don't see any errors from hardware or anything relating to sleep in the application log that would point to what is going on either. How can I find out which app is triggering this? EDIT: I confirmed that temperature wasn't the issue. I think it's important to keep in mind that this condition only happens after the first sleep. If I reboot, the problem goes away until I put it to sleep, after which it sleeps on it's own every few minutes. Is there no way to capture which app is calling the sleep routine?

• Print job leaves queue but document isn't printed

  - by midnightstar

  I'm dealing with an HP Deskjet F380 All-in-One printer. It's connected via USB to a desktop running Windows 7 Enterprise x64. If I attempt to print something like a web page or a word document, the print job will show up in the print queue and the printer would stir. By stir, I mean, it would seem to prepare itself to print. However, the print job would then leave queue (I'm thinking the computer sees it as completed) and the printer would never actually print anything. However I went into Printers and Devices under the Windows start menu, into printer properties, and print a test page, the test page would print out successfully. I attempted to uninstall and re-install the printer drivers for the printer, but the printer would continue the same behavior afterwards. I also connected the printer to another computer and the printer will print just about anything. I also checked to make sure that the computer the printer needs to be connected to was update to date as far as the OS. The machine is fully up to date. I played with the way the computer handles printer spooling. Under the printer properties, under the "Advanced" tab, I had the print job print directly to the printer. In all these instances, the same behavior continues. I've restarted the printer spooling service. I've also gone under C:\Windows\System32\spool\PRINTERS and deleted files that were sitting in the folder. I have ran SFC /scannnow and the system found no errors in the system's integrity. I had the computer and printer make a cold reboot individually. The only lead I really have going for me is that since the printer prints on other PCs, I can only assume that there is something wrong with the way the PC is configured.

• hg clone has stopped working on my Vista box

  - by vkraemer

  I have a Windows Vista machine that has been connecting to http://hg.netbeans.org productively for awhile... until recently. Lately, when I attempt to pull or clone, the update appears to stall... I see the following messages on the screen when I attempt to clone: destination directory: web-main requesting all changes adding changesets And then... nothing happens. I have opened the Task Manager and there doesn't appear to be any significant network activity for HOURS. I can contact the server with FireFox and see the proper output. I can clone from the repo with Solaris and/or Mac OS X... so the issue doesn't appear to be at the 'other end'. I had been running a fairly old version of Mercurial before this started happening. After it started happening, I upgraded to Mercurial 1.5.2.. which did not help resolve the issue at all. What are the likely causes and work-arounds for this?

• Oracle Linux screen freezes during installation

  - by Fearless

  I was installing Oracle Linux 6.4 on a server, and the screen suddenly froze. Here were the previous steps: I put in the disk, clicked install, checked the disk (no errors), did pre-install setup (clock, root password, host+domain name, etc.), configured two 40GB hard drives in a RAID1 array (no swap, 3100mb encrypted raid partitions, ~100mb ext4 partition mounting to /boot, encrypted ext4 RAID device with mounting to /), selected packages, hit continue. The system did its short preinstall processes, then when to the main installation screen with the long status bar. The installer proceeded like always, but around package 250 out of ~1000, the screen suddenly went black with a text cursor in the upper left corner of the screen and the mouse cursor in its previous place. Neither cursor moved and the only thing that triggered a response was a ctrl-alt-delete that rebooted it. I have run this in VMs before without this issue. Memtest hasn't reported anything, and the media check went smoothly. The machine has supported Ubuntu server without issues before. Any ideas? I have tried booting after that, but the grub bootloader tries to find fd0 for some reason (I have no idea why it would search for the floppy disk). UPDATE My server successfully installed, but won't boot up. I think that, for some reason, it is still using the old bootloader from the previous installation. Any ideas on how to fix that?

• (Some) security perms in WinXP corrupted (shows GUID instead of username)

  - by Andy

  I've been using my Win XP machine (part of a domain) over the holiday period, so until yesterday it hadn't rebooted for about five days. I used it yesterday perfectly fine and shut it down. When I switched it on this morning the majority (but not all) of my shortcut links in the Quick Launch toolbar showed as generic file icons. If you open the folder and get properties on one of the failing shortcuts it says ''Target type: This is not a valid shortcut''. Then in Outlook I noticed my signature wasn't showing (I checked my sent folder and the sig was ok yesterday). Checking the signature folder, I can't see the security tab on any of the sig files, and I have an access denied message on trying to open them. I can see the security tab on the signature folder itself, just none of the contents. If I try and use the parent folder's security tab and ''Replace permission entries on all child objects with entries shown here that apply to child objects'' it appears to work fine, but makes no actual difference. I logged in as administrator and saw that the owner of the files showed up as a GUID (clearly should've been my account in its place). Any ideas what might have made that happen? So far I haven't heard any similar complaints from anyone else at the office...

• I can't change mysql port (5.6.12) changing the lines of my.ini (windows 8)

  - by videador

  I was trying to change the port of my mysql server in my local machine but i can't. The version of mysql is 5.6.12, is an installation from wamp and I am on Windows 8. I change these lines in my my.ini file located in (C:\wamp\bin\mysql\mysql5.6.12). [client] #password = your_password port = 3307 socket = /tmp/mysql.sock [wampmysqld] port = 3307 socket = /tmp/mysql.sock key_buffer = 16M max_allowed_packet = 1M The previous values were 3306. Ok then I've reset the server installed, but it doesn't works, the mysql server is still running on 3306. Then, I rename the path of the services with this, to make sure that the my.ini is read by the mysql instance. c:\wamp\bin\mysql\mysql5.6.12\bin\mysqld.exe --defaults-file="C:\wamp\bin\mysql\mysql5.6.12\my.ini" wampmysqld But nothing, it stil doesn't works. My last bullet was to copy the content of my.ini to a file my-default.ini (a file that is placed in C:\wamp\bin\mysql\mysql5.6.12\ and that I don't know what is its mission). However it still doesn't work and the port is still 3306.

• Computer is dying--what should I be looking for?

  - by Will

  Okay, I'm a bit knowledgeable with pooters and such, but i'm confused. My computer is dying slowly, and I'm not sure what part is causing this. Computer details: Vista, dell machine, intel Q6600, 2.4 Core Duo (quad core), standard memory and drive (unknown manufacturer). Symptoms: I would best describe the symptoms as memory corruption. After a couple days on, I start getting applications crashing or failing to open for a lack of "resources". Sounds are corrupted. Onscreen text gets corrupted; the characters of text are garbled, not the pixels on the screen. Video memory seems untouched as I haven't seen any misplaced pixels. Recently I've lost files on disk. I've also experienced errors reporting a supposed lack of disk space, even though I have fifty gigs free. There was one point where I couldn't get to the POST when booting up. After I cleaned everything (see next) this hasn't happened. Diagnostic steps: First thing I did was clean the case. There was a lot of dust buildup on heatsinks, so I cleaned all that up. No help. Next, I disconnected and reconnected everything, from power cables to memory (did not reseat cpu). No change. Last, I ran the standard vista memory diagnostics and ran checkdisk. Both reported no errors found. I have not run any POST tests, now that I think about it. I'm at a loss at this point. Disk appears fine, memory too. I'd expect motherboard issues to result in the thing not booting up, yet it does every time. What should I be looking at? What more can I do?

• Email Proxy Ideas

  - by jtnire

  Hi Everyone, I wish to host some managed email servers for some customers. Each customer will have their own email server which will be an all-in-one virtual machine running postfix, dovecot and some webmail suite. Even though each customer will have their own server, I do not wish to give each email server it's own public facing IP. I wish to avail the use of proxy servers so all customers use the same public IP. As for the "smtp-in" from the public internet, this isn't a problem as I can set up many mx servers (using postfix) which will store-and-forward the mail to the correct server (using transport maps). As for the IMAP access from the customer, I was thinking of using perdition which is an IMAP proxy - I believe that this will suit my needs. I am confused however on what to use for the "smtp-out" proxy. The customers will have to authenticate with their receptive email server, however they will have to go via a proxy of some sort as they won't have direct access to their server instance. It probably can't be a store-and-forward proxy either. Does anyone have any idea on what I could use here? Many Thanks

• How to use git to manage one codebase but have different environments

  - by emostar

  I'm using git for a personal project at the moment and have run into a problem of having one codebase for two different environments and was wondering what the cleanest way to use git would be. Main Desktop I Use this machine for most of my development. I have a git repository here that I cloned off of an empty repository that I use on my internal server. I do most of my work here and push back to the internal server so I can use that as a master of truth and to ease making backups. Laptop I sometimes want to code on the road, so I did a clone from the internal server and created a new branch called "laptop-branch". Unfortunately some directories MSVC++ version are different than from the Main Desktop environment. I just modified the files in the "laptop-branch" and committed them there. Now I did a lot of changes while on vacation with my laptop, and want to push them to origin, but don't want the changes I made that were related to directories and compiler versions to be pushed back to origin. What would be the best way to get this done?

• IIS 6.0 https not working "connection was reset"

  - by cad

  Application Server Windows Server 2003 SP2 with IIS 6.0 IIS has a "Default Web Site" (port 18000, ssl 443, ID=1) with a certificate created by me. I have an specific site called "scj.galaxy.Weekly" (port 80, ssl 443, ID=1272369728) that is working fine. I have an entry in windows/system32/drivers/etc/hosts that links galaxy.Weekly.scjdev.ds to the server ip in both my local machine and in the application Server. These sites works: http://scj.galaxy.weekly/test.html works http://scj.galaxy.weekly/test.aspx works But https://scj.galaxy.weekly/test.html fails Error message is: The connection was reset The connection to the server was reset while the page was loading. The certificate was working fine for months. It was created with something similar to this: Selfssl /N:CN=*.scjdev.ds /V:3650 /S:1 /P:443 I have tried several options and none of them are working: 1) Create a certificate only in "Default Web Site" and link it to SecureBindings with command prompt cscript adsutil.vbs set /w3svc/1272369728/SecureBindings ":443:galaxy.Weekly.scjdev.ds" 2) Create a certificate only in "Galaxy Site" and link it to SecureBindings 3) Create a certificate in both and link them to secureBindings. Probably I am missing an step or something, but I can't see it. Here is the relevant config of Galaxy Site: <IIsWebServer Location ="/LM/W3SVC/1272369729" AuthFlags="0" LogPluginClsid="{FF160663-DE82-11CF-BC0A-00AA006111E0}" SSLCertHash="c36a514a0be90fbc121d9c19bb052842289d5aee" SSLStoreName="MY" SecureBindings=":443:galaxy.Weekly.scjdev.ds" ServerAutoStart="TRUE" ServerBindings=":80:galaxy.Weekly.scjdev.ds" ServerComment="galaxy.Weekly.scjdev.ds" > </IIsWebServer> <IIsWebVirtualDir Location ="/LM/W3SVC/1272369729/root" AccessFlags="AccessRead | AccessScript" AppFriendlyName="Default Application" AppIsolated="2" AppRoot="/LM/W3SVC/1272369729/Root" AuthFlags="AuthAnonymous | AuthNTLM" DefaultDoc="Default.aspx" DirBrowseFlags="EnableDirBrowsing | DirBrowseShowDate | DirBrowseShowTime | DirBrowseShowSize | DirBrowseShowExtension | DirBrowseShowLongDate" Path="D:\Webs\Galaxysite" ScriptMaps="some config...

• Windows 7 pc freezes for an indeterminate amount of time after unlocking

  - by pikes

  Not sure if this type of question is appropriate for this forum, but I've tried everything I can think of to solve this problem aside from format/reinstall. I recently got a new work PC (Dell optiplex 755) with windows 7 professional x64. Standard developer software installed for .net development: VS2008, VS2005, SQL management studio, office 2007, etc. Recently I've been having this weird problem where after I lock my pc, when I try to unlock it, the screen will be black for awhile after unlocking. I can ctl+alt+del and put my password in but then it just goes black. The amount of time on the black screen seems to be related to the amount of time I am away from my PC. If only away a few minutes, it'll take about a minute to get to the desktop. If away for an hour, could take up to 15 minutes. If I lock it and go home for the night, I have to restart my PC in the morning (I've let it sit for an hour after a night of being locked and nothing happened). It doesn't do it every time but definitely the majority of the time. One weird thing I've seen is that if I remote into my machine before trying to log back in it does not do it. I uninstalled all software back to the point when I remember it started happening and it still does it. I was using this PC for a few weeks without this problem happening at all. Anyone know what my next troubleshooting steps could be? My IT department tried to fix it by moving my old profile to another disk and having me log in, effectively recreating a profile from scratch but that didn't solve it. As I said above if this isn't the right forum for these types of questions please let me know. Thanks in advance!

• exchange server 2010 with multiple domains

  - by air

  i have one exchange server 2010, which is working fine with one domain. my exchange is working as follows pop3 collector collect emails from one master catchall account and then deliver to exchange server, this working perfect. now what i want to add another domain to same exchange, i have added new domain as trusted domain & email policy and this new domain email account works fine with internal emails. now what i have done, i again forward new email account to same catchall account. but if i send email from any other external email address email is bounce, i can see email receive by pop3 collector but bounce by exchange server. to make you more clear let me explain logic on which i am working. i have 2 domains 1. domain1.com ([email protected]) 2. domain2.com ([email protected] -->[email protected]) now on my machine with exchange server i have pop3 collector which collect all emails from [email protected] and forward to exchange 2010 server. all emails to domain1.com is working perfect but when i send email to [email protected] this email redirect to [email protected] perfectly but when exchanger server receive this email, it bounce. i have also study the url link text and follow the whole process but no success. i also check that my DNS/MX is working fine as the bounce message is going from my exchange server. EDIT the only problem is with accepted domain, as email come to exchange server then bounce back. i just try this today i create one user called test, then i goto his properties -- email there was only one email account [email protected] i try to send email to [email protected] from internet (email bounce) then again i go to test user properties -- email and Add one email [email protected] again u try to send email to t*[email protected]* from internet (email received) i think the only problem is with accepted domain but in hub transport , it shows accepted is there any way to check does domain is properly accepted or not in exchange 2010 server.

• cpusets not working - threads aren't running in the cpuset I specified?

  I have used cpuset to shield some cpus for exclusive use by some realtime threads. Displaying the cpuset config with the test app RealtimeTest1 running and its tasks moved into the cpusets: $ cset set --list -r cset: Name CPUs-X MEMs-X Tasks Subs Path ------------ ---------- - ------- - ----- ---- ---------- root 0-23 y 0-1 y 279 2 / system 0,2,4,6,8,10 n 0 n 202 0 /system shield 1,3,5,7,9,11 n 1 n 0 2 /shield RealtimeTest1 1,3,5,7 n 1 n 0 4 /shield/RealtimeTest1 thread1 3 n 1 n 1 0 /shield/RealtimeTest1/thread1 thread2 5 n 1 n 1 0 /shield/RealtimeTest1/thread2 main 1 n 1 n 1 0 /shield/RealtimeTest1/main I can interrogate the cpuset filesystem to show that my tasks are supposedly pinned to the cpus I requested: /cpusets/shield/RealtimeTest1 $ for i in `find -name tasks`; do echo $i; cat $i; echo "------------"; done ./thread1/tasks 17651 ------------ ./main/tasks 17649 ------------ ./thread2/tasks 17654 ------------ Further, if I use sched_getaffinity, it reports what cpuset does - that thread1 is on cpu 3 and thread2 is on cpu 5. However, if I run top -p 17649 -H with f,j to bring up the last used cpu, it shows that thread 1 is running on thread 2's cpu, and main thread is running on a cpu in the system cpuset (Note that thread 17654 is running FIFO, hence thread 17651 is blocked) PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ P COMMAND 17654 root -2 0 54080 35m 7064 R 100 0.4 5:00.77 3 RealtimeTest 17649 root 20 0 54080 35m 7064 S 0 0.4 0:00.05 2 RealtimeTest 17651 root 20 0 54080 35m 7064 R 0 0.4 0:00.00 3 RealtimeTest Also, looking at /proc/17649/task to find the last_cpu each of its tasks ran on: /proc/17649/task $ for i in `ls -1`; do cat $i/stat | awk '{print $1 " is on " $(NF - 5)}'; done 17649 is on 2 17651 is on 3 17654 is on 3 So cpuset and sched_getaffinity reports one thing, but reality is another I would say that cpuset is not working?

• Two cisco gigabit switches refuse to link to each other. Any idea why?

  - by Prody

  I have 3 Linksys SR2024 switches which are basically non-managed 24 port Gbit + 2 miniGBIC. I now had to add another switch to the network, and my provider didn't have the SR2024 switch anymore, so I got the Cisco SLM2024 which was a bit more expensive. It's pretty much the same thing but with management (that I don't need). So I've connected the SLM2024 to a SR2024 via Cat6 cable, and for some strange reason, I get no link. If I connect any machine with a Gbit NIC to both switches, it links with 1Gbit autonegotiated. If I connect the SLM2024 to a non-Gbit switch (I have a cheap 4port ASUS switch), it will link just fine on 100Mbit full duplex. Since the SLM2024 has management, I've tried to see if something is misconfigured on it's side, but it's not, it advertises 1Gbit and lower. (hence the machines connecting succesfully at 1Gbit). Since the SR2024 that I'm trying to connect it to also connects successfully with another SR2024 and other Gbit machines, it means that it advertises Gbit too. But for some reason when I link the SR2024 to the SLM2024 I get no link. Please note that I've properly tested the wire. Does anyone have any idea what's wrong?

• Removed Old Domain Trust. Now Progress (9.1D) can't open DB File

  - by RLH

  My company has an old server, running Progress 9.1D on a Windows 2000 VM, which was used by our company OS (Vantage 6 by Epicor.) Vantage was our primary OS for a very long time. About 2 years ago, we migrated to a larger, corporate OS and we cancelled our service contract with Epicor. Yesterday, we removed an AD trust between the corporate domain and our old AD domain we used in the days of Vantage. After restarting the virtual server, I have been able to start the ProService for 9.1D Windows service, however, I can not get Vantage to start back up. When I run the application, I get the error in the message listed below. Transcript: ** Could not connect to server for database [progress db file], errno 0. (1432) How can I fix this? FYI, I haven't had to work with Progress in years and even then I wouldn't have considered myself a "novice"-- I'm even less knowledgeable than that title would suggest. Vantage had a lot of internal tools and I recall that Epicor support managed to prevent .pf scripts from being executed. If there was a Progress specific patch that needed to be applied, you had to do it within the Vantage software OR they had to remote into the machine to fix this. I may not be able to run a .pf script but I do know that I can log into the console-based server application. (Yes, I can't even recall which utility that was called. It is sad.) It's been a long time and I never had to digg into Progress that much. Please help and feel free to ask questions. If you need more info, I'll update this post.

• Good support to multiple desktops AND multiple monitors in Linux (Ubuntu)?

  - by Somebody still uses you MS-DOS

  I'm starting to have A LOT of opened windows in my machine. Sometimes within a project, I have e-mail/task management/personal e-mail/twitter, and a lot of different opened applications/terminal in my Linux environment. Nowadays I have 4 worspaces: Corporate management (e-mail) and corporate messenger; Work (Documents, Requisites) Dev (Development, All gVim windows, terminal and Firefox for development) Personal (Personal stuff: personal e-mail, delicious, twitter and so on) Sometimes it would be interesting to have different workspaces to projects instead of this configuration I have nowadays that are classes of work (bad name, I know, but I think you got the idea). I'm starting to think about using two monitors: one with Corporate Management, Work and Personal. The second monitor is only the development state: each workspace here is about a project being worked on instead of groups of works like before. A workspace may be implementing different classes for example. My question is: I just want to change to a second monitor using the mouse. I want to still be able to change workspaces in the same monitor using keyboard shortcuts. The keyboard shortcuts wouldn't change monitors, just worskpaces on the same monitor. Does Linux (Ubuntu 10.04 Lucid Lynx) support this envisioned setup? If so, how?

• Best format for hard drive for Windows and Mac?

  - by Neil

  I have a 500 GB USB External Hard Drive. I need four partitions on it, for the following purposes: 160 GB for a bootable backup of my Mac. 160 GB for a bootable backup of my Windows. 11 GB for a bootable Snow Leopard Install Disk Rest as for file storage. Now I need a partition table which will get recognised on both Windows and Mac, without needing extra software on Windows, which will let me keep bootable copies of both OS'es, but let me access the file storage from both OS'es. Currently, I have a GUI Partition Table, with Mac OS Extended (Journaled) Partitions for the two backups, Mac OS Extended for the Install Disk, and NTFS for the file storage. While this gets recognised perfectly on my Mac, thanks to an NTFS for Mac driver from Paragon, when connected to Windows, the drive is detected by the machine (listed in Safely Remove USB), but not recognised in Windows Explorer unless I install MacDrive, which is not feasible for me to install on public Windows Machines I might wanna access my storage area on. Can someone recommend the best combination of formats and software/drivers to get this done seamlessly?

• VPN: Disable class based route addition for Windows XP/Vista

  - by brgsousa

  Paraphrasing this SuperUser link: When you set up a VPN, the Windows default is to enable "Use default gateway on remote network." A new default route is added to the routing table pointing to the remote network's gateway, and the existing default route has its metric increased to force all Internet traffic to traverse the tunnel and use the remote network's gateway. All traffic uses the VPN, and traffic destined for the outside world is directed to the remote gateway. When the VPN drops, the route to the remote gateway is removed and the original default route is set back to the original metric. Unchecking "use default gateway on remote network" means that new default route isn't added, so Internet traffic goes out the local gateway, but a new classful route is added to the routing table, using the local adapter's IP, pointing down the VPN. Only traffic destined for the classful network of the local adapter goes down the VPN. This may not be what you want. Checking "Disable class based route addition" means that classful route isn't added to your machine when the VPN starts up, and you'll need to add the appropriate routes for networks that should be routed through the tunnel. But, the option "Disable class based route addition" is available ONLY for Windows 7. How can I do something like that for Windows XP or Vista since they don't have that option? I have searched about for that but, no solution yet.

• Windows 7 product key, which is the valid one - in registry or on a sticker?

  - by me how

  I am not too familiar with the software licensing and how this all works, but I have a question regarding Windows 7 and partially Office - generally Microsoft products. I have been asked to assist our IT guy who wants to collect all the product IDs for Windows 7 and Office. I haven't been given much details how to go about it and how to collect it. After a bit of research I have decided to use a freeware that pulls the software licenses out of the registry. I thought that was the easiest and would provide the most accurate product IDs. I've used Belrac Avisor to obtain all the informations. It turns out that about 25 machines use the same product key. I have asked if the company has bought a commercial license or something but there isn't anyone available at the moment who could answer my question. I have told the IT guy that there are 25 machines using the same product key and asked if that is alright. He told me to go around and write the product keys from the sticker(label) on each machine. I am just not quite sure if that's the right approach specially that the numbers do not match.... So, now I see that the numbers aren't matching and my question is in terms of software licensing which is the VALID and correct product key to provide if ever questioned about software license? Is it the number on the sticker or is it the number stored in the registry?

• What could cause a dual-monitor PC to suddenly stop using one of the screens?

  - by raldi

  I've got a dual-monitor setup using a GeForce 7900GT that was working fine for over a year... then suddenly, only one of the screens works. It's not OS-related, because even on startup, only one screen displays the BIOS checks. In the past, both screens would show it together. I didn't change anything to trigger this The monitor that gets a signal is random -- sometimes the one on the left goes black, sometimes the one on the right. The monitors and their cables are good -- I can switch both or either, and I get a signal just fine. They're plugged in, too. It's not the video card, either -- I have an identical 7900GT in another machine, and swapping the two didn't fix anything. It's not dust on the motherboard -- I pulled everything out, cleaned it off, checked for obvious damage, put it all back together, and no change. My next two steps are going to be to reset the CMOS info and to try swapping out the motherboard. Before I do that, does anyone have any other ideas?
