• Is it possible to configure a CDN so that it will step out of the way for a subset of regional IPs?

  - by rwired

  We have a website which targets customers in China, both expat and local Chinese. We have an ICP license which allows us to host in a datacenter inside China. Internet in China is actually as fast as anywhere else (faster than most places actually), so long as the content is served-up within the boundaries of the Great-Firewall. Anything that crosses the wall is horribly slow. The problem is that most expats have some sort of VPN installed so that they can access all the blocked stuff. What this means is that when they access our site, the traffic first has to go out of China through the firewall to their VPN, and then back in. The performance is terrible, worse than if we were just hosting outside of China directly (which we used to do before the ICP was issued). So I want to use a global CDN to mirror the site automatically, but I only want to deliver the content via the CDN if the user's request IP address is outside of China. Inside China I would like the content to be served by our own server. I also want to be careful with the domain names. We currently use www.xxx.com and www.xxx.cn for language selection purposes, as these perform well in SEO on Google (which the expats use), and Baidu (which the locals use). If possible I would like to avoid having one domain on the outside, and the other on the inside since not all expats use a VPN, and some Chinese speakers also use VPNs. Also some of our legitimate customers in both languages are from outside of China. I also don't want to resort to using something like www2.xxx.com/cn for the outside connection if at all possible, since I have worries about duplicate content and canonical URLs ruining our SEO (unless you know of a quick fix for that). CDNs I'm considering are: Google PageSpeed, CloudFlare, Amazon CloudFront. None of which have datacenters inside China. I have complete control of the .com DNS zone records, but the .cn zones are under the control of the domain issuing body in China. I'm not sure at this time if they would allow even a CNAME to point to an IP outside of China (although I don't see why not). They no longer allow outside registrars like they used to.

• Installing the Newest KeePass for MacOSX from Source

  - by firebush

  I've transitioned our passwords to KeePass. LastPass looks cool, but I prefer a system where we control the database locally rather than it being kept in the cloud. I have a windows and Linux system and both are able to access our KeePass database easily. On my Linux system (Ubuntu), I simply installed KeePass via synaptic and it just worked. So everything was working great, until my wife tried to set up things on her MacBook to access the database. Huge problems. It was so easy on Linux that I didn't expect there to be issues there. In case it's helpful, she's running a fresh install of Mac OSX 10.5.8, Leopard. We simply went to the download site for KeePass: http://keepass.info/download.html Clicked on the link titled KeePass 2.x for Mac OS X from which we retrieved Mono 2.10.5 and KeePass 2.18 from that site (the packages posted there at the time of this writing). Mono installed without problems (at least, none that we saw). She opened the KeePass image and dragged it to the Application side, unpackaging it there. According to the instructions on the KeePass installation instructions, she opened a terminal, changed to the directory in /Applications containing KeePass.exe, and ran it through mono: mono KeePass.exe No application opens at all - we see a blip for it, but then it immediately goes away, indicating to us that it is crashing. Also disconcerting, I see that people are throwing fits about copy-and-paste not working for KeePass 2.18 on MacOSX. Judging from the 2.19 addresses the copy/paste issue. I'm hoping that version will solve all our issues. So here's my question: how can I try out 2.19 on her system. It doesn't seem to be packaged like the 2.18 one is. But we're not scared of building it. I see that the source for 2.19 is here (at the bottom of the page). Can I just download that to her machine somewhere and run something to build it? I'm familiar with automake but not with building .NET source, so please answer gently if this is stupidly easy. :^) btw: tomorrow's my wife's birthday, and this is getting her down. If you know how to navigate these issues, it would be a nice birthday gift for her. Thanks in advance! Update I'll post this since it might be helpful to someone else: I got KeePass 2.18 to run by updating Mono to 2.10.9 (rather than the 2.10.5 given by the site above). With the later version of Mono, it runs without crashing. And yet, I do see the copy and paste issue that others see. I can open a database on her machine, but the incorrect data get's copied. So again, can someone help me install KeePass 2.19? Thanks!

• Looking for Fiddler2 help. connection to gateway refused? Just got rid of a virus

  - by John Mackey

  I use Fiddler2 for facebook game items, and it's been a great success. I accessed a website to download some dat files I needed. I think it was eshare, ziddu or megaupload, one of those. Anyway, even before the rar file had downloaded, I got this weird green shield in the bottom right hand corner of my computer. It said a Trojan was trying to access my computer, or something to that extent. It prompted me to click the shield to begin anti-virus scanning. It turns out this rogue program is called Antivirus System Pro and is pretty hard to get rid of. After discovering the rogue program, I tried using Fiddler and got the following error: [Fiddler] Connection to Gateway failed.Exception Text: No connection could be made because the target machine actively refused it 127.0.0.1:5555 I ended up purchasing SpyDoctor + Antivirus, which I'm told is designed specifically for getting rid of these types of programs. Anyway, I did a quick-scan last night with spydoctor and malware bytes. Malware picked up 2 files, and Spydoctor found 4. Most were insignificant, but it did find a worm called Worm.Alcra.F, which was labeled high-priority. I don’t know if that’s the Anti-Virus Pro or not, but SpyDoctor said it got rid of all of those successfully. I tried to run Fiddler again before leaving home, but was still getting the "gateway failed" error. Im using the newest version of firefox. When I initially set up the Fiddler 2.2.8.6, I couldn’t get it to run at first, so I found this faq on the internet that said I needed to go through ToolsOptionsSettings and set up an HTTP Proxy to 127.0.0.1 and my Port to 8888. Once I set that up and downloaded this fiddler helper as a firefox add-on, it worked fine. When I turn on fiddler, it automatically takes my proxy setting from no proxy (default) to the 127.0.0.1 with Port 8888 set up. It worked fine until my computer detected this virus. Anyway, hopefully I've given you sufficient information to offer me your best advice here. Like I said, Spydoctor says the bad stuff is gone, so maybe the rogue program made some type of change in my fiddler that I could just reset or uncheck or something like that? Or will I need to completely remove fiddler and those dat files and rar files I downloaded? Any help would be greatly appreciated. Thanks for your time.

• USB mouse connecting and disconnecting randomly

  - by Kalec

  I've bought an acer aspire 5742G about 2 months ago or so and it's been running great, but sometimes I used to hear the windows error beep but I had no idea what was causing it since the "bug" was automatically fixed so fast I couldn't even see an error message (also it kinda always happened when I was busy also, either in a game or while doing my homework). Later on my mouse would simply not work for 3-5 seconds then work again, I thought nothing of it at the time. I also had a problem where it only worked in one usb and one only. To move it I had to remove the battery, unplug the laptop and hold the power button for 2 minutes to reset the bios settings. Since today though it went nuts. Sometimes it disconnects / reconnects 12 times in 10 seconds and windows just keeps beeping till I unplug it, then it runs smooth for 5-6 minutes then it goes nuts again. Other times it seems like it skips (disconnects for a fraction of a second) other times just for 2-3 seconds. But this is incredibly frustrating. Sometimes the power just goes down (the laser turns off) and well that at least I would understand but this is a rare occurrence. Now I know the usb ports work since I have a lot of other devices connected and I tried the mouse on a room m8's laptop so the mouse also works. My only conclusion is that it's an operating system / settings bug and / or problem (I have tried the mouse in all ports by the way). All drivers and bios are up to date (maybe except mouse but I can't seem to update that and the mouse has no name, just a serial number which helps with nothing. Still it worked till today and nothing should have changed any way). I have made sure windows can't shut it down to save power (in device management). Also I tried to delete the drivers and re-install them, rebooting and the power button trick but nothing. Most I have done is get rid of the 12 disconnects / reconnects every 10 seconds :) but that's all :( I would buy a new one but I'm afraid it might do the same thing. ****EDIT****** Tried the mouse again at a friend but now it didn't even install it's software nor did the update work. Think I'll just buy a new one but I'd still like a suggestion at least so I'll leave this open #### EDIT 2 Now it works again, I can't explain this. Still thinking of getting a new one though

• 64-bit linux kernel only seeing 3 of 4GB after upgrade...

  - by Blaine

  Hey everyone. I am running Ubuntu 9.04 64-bit on my macbook. I had 2GB of ram before, and everything ran great. I just upgraded to 2x2GB (4GB), but my system only sees 3GB of it. OS X, which I am dual booting, sees all 4GB. Also, my video performance is incredibly lacking. Before the upgrade my compiz benchmark was full at 80fps, and now it is at 22fps with very choppy window dragging. Has anyone ever heard of this on a 64-bit kernel? I just don't quite understand what could be the issue. 10$ uname -a Linux macbook 2.6.28-15-generic #49-Ubuntu SMP Tue Aug 18 19:25:34 UTC 2009 x86_64 GNU/Linux $ free -m total used free shared buffers cached Mem: 2953 1031 1921 0 114 427 -/+ buffers/cache: 489 2463 Swap: 7812 0 7812 9$ lsmod Module Size Used by i915 77960 2 drm 123232 3 i915 binfmt_misc 18572 1 ppdev 16904 0 btusb 21784 2 bridge 63776 0 stp 11140 1 bridge bnep 22912 2 vboxnetadp 109356 0 vboxnetflt 116972 0 vboxdrv 1721612 1 vboxnetflt uvcvideo 69640 0 compat_ioctl32 18304 1 uvcvideo videodev 45184 2 uvcvideo,compat_ioctl32 v4l1_compat 23940 2 uvcvideo,videodev lp 19588 0 parport 49584 2 ppdev,lp snd_hda_intel 557492 3 snd_pcm_oss 52352 0 snd_mixer_oss 24960 1 snd_pcm_oss snd_pcm 99464 2 snd_hda_intel,snd_pcm_oss arc4 10240 2 snd_seq_dummy 11524 0 ecb 11392 2 snd_seq_oss 41984 0 snd_seq_midi 15744 0 snd_rawmidi 33920 1 snd_seq_midi snd_seq_midi_event 16512 2 snd_seq_oss,snd_seq_midi snd_seq 66272 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event ath9k 310584 0 snd_timer 34064 2 snd_pcm,snd_seq snd_seq_device 16276 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq mac80211 251528 1 ath9k iTCO_wdt 21712 0 iTCO_vendor_support 12420 1 iTCO_wdt joydev 20992 0 video 29204 0 snd 78920 15 snd_hda_intel,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device applesmc 37700 0 output 11648 1 video soundcore 16800 1 snd pcspkr 11136 0 cfg80211 43680 1 mac80211 appletouch 19972 0 isight_firmware 11520 0 input_polldev 12688 1 applesmc intel_agp 39408 1 snd_page_alloc 18704 2 snd_hda_intel,snd_pcm led_class 13064 2 ath9k,applesmc hid_apple 15872 0 usbhid 47040 0 ohci1394 42164 0 ieee1394 108288 1 ohci1394 sky2 63364 0 fbcon 49792 0 tileblit 11264 1 fbcon font 17024 1 fbcon bitblit 14464 1 fbcon softcursor 10368 1 bitblit Some information from dmesg: [ 795.820163] ACPI: EC: GPE storm detected, transactions will use polling mode [ 1762.709516] [drm:i915_getparam] *ERROR* Unknown parameter 6 [ 1763.078130] [drm:i915_getparam] *ERROR* Unknown parameter 6 [ 2362.760889] [drm:i915_getparam] *ERROR* Unknown parameter 6 [ 2416.352084] ACPI: EC: missing confirmations, switch off interrupt mode.

• How to move Mailboxes over from old Exchange 2007 to new EBS 2008 network?

  - by Qwerty

  Hi all, This q is similar to: http://serverfault.com/questions/39070/how-to-move-exchange-2003-mailbox-or-store-from-2003-to-2007-on-separate-networks Basically I am trying to move our exchange mailboxes over to a test domain that is hosting EBS2008 with Exchange 2007. We plan to move as soon as we can when we have our exchange data over. I have tried moving a db with mailboxes over but cannot get it to mount in the new Exchange in any way possible, including mounting it onto a recovery store. From my understanding the ONLY prerequisite for moving Exchange DBs across is that it must have the same Organizational name (unlike previous versions of Exchange). If anyone has any insight as to why I cannot mount and simply reattach the mailboxes, please give me an idea as to what could be wrong. It should be as simple as this. Note that the DBs I have are in a clean state. I cannot use ExMerge because I am not running any mailboxes on 2003. I have also tried using a 32bit Vista machine with the Export-Mailbox cmdlet to extract mailboxes but anything I do to it results in Permission errors. I have tried to troubleshoot these with no success. I am running in full admin with proper exchange roles and yet it still gives me access denied errors: Export-Mailbox : MapiExceptionNetworkError: Unable to make admin interface conn ection to server. (hr=0x80040115, ec=-2147221227) Also some errors show in the management console: get-MailboxDatabase Completed Warning: ERROR: Could not connect to the Microsoft Exchange Information Store service on server TATOOINE.baytech.local. One of the following problems may be occurring: 1- The Microsoft Exchange Information Store service is not running. 2- There is no network connectivity to server TATOOINE.baytech.local. 3- You do not have sufficient permissions to perform this command. The following permissions are required to perform this command: Exchange View-Only Administrator and local administrators group for the target server. 4- Credentials have been cached for an unpriviledged user. Try removing the entry for this server from Stored User Names and Passwords. Why I have to use a 32bit machine to export a simple .pst file is beyond me... So yeah I am now out of ideas and any help would be great! Thanks in advance.

• Establishing a web page bookmarking process - looking for ideas to improve

  - by Matt

  Like many others, I have a process for bookmarking web pages to read later. My requirements for web page bookmarking are: Ability to bookmark pages must be available from all (within reason) platforms - PC/browser, mobile device, etc. Bookmarks must be centrally stored (implicit from #2) so that I can read the bookmarks from anywhere/any device Full text of web pages must be stored Bonus features would be: Bookmarks and page content should be full text searchable Maintain an archive indefinitely Distinguish between what's read vs. unread Bookmarked page content is cleaned up, e.g. ads eliminated, unnecessary html removed, pages better formatted for reading My current process (which addresses most of these requirements) is as follows: I set up a Gmail account with 2 labels, "Bookmarks Unread" and "Bookmarks Read" Gmail filters set up such that depending on the form of the address (using Gmail's '+string' functionality in addresses), the incoming bookmark gets labeled appropriately On each of my browsers/devices, I have an address book entry for [email protected] and [email protected]. If I want to clean up the page content, I use the Readability bookmarklet which does a great job of giving me the essential content only Anywhere I have Firefox, I use the Send Page by Email extension which, with 2 clicks, allows me to send the cleaned-up Readability page URL and content to one of the above email addresses. Where I don't have Firefox (e.g. iPhone or other mobile device) I use the native ability to send the current link via email (most/all apps have them, including the browser, RSS readers, NYTimes, etc.). In most cases (unless it's built into the particular app), this won't include the page body. The process is almost perfect. I've got the central access and ubiquitous access of Gmail as the storage mechanism, full text searchability (due to Gmail, but of course only for the URLs I send from that Firefox extension), a cleaned up page due to Readability, ability to read offline (assuming I use an IMAP client against Gmail) and permanent archiving of content, including what's been read vs. unread. The missing pieces are: The Send Page by Email Firefox extension seems to only send X bytes of a web page. Or some portion. So it limits my full text searchability. Where I don't have Firefox, I can only send the link, so no full text search at all in those cases. Instapaper looks like it meets most of my requirements (and bonus items). The only downside to me (personal preference) is that central storage is based on Instapaper vs. something more broad like Gmail, which as a generalized service and with Google behind it pretty much means it's permanent. I'm not too hung up on this, but I would definitely prefer to keep Gmail if possible. An upside of Instapaper is that it does the page clean-up as well as stores the entire page content, unlike my Firefox extension. Thoughts on addressing the gaps and improving this process further?

• Network use of Gaming PC

  - by Matthew Patrick Cashatt

  Background After YEARS of waiting, I built the custom gaming PC of my dreams: Intel i7 - 975 Extreme Edition 3.3ghz (overclocked to 4.0) ATI Radeon 5970 2gb Corsair 256 gb SSD Drive 2 TB Sata II 3.0 7200rpm data drive 12 GB Kingston Hyper-X (1600mhz) DDR3 Windows 7 Ultra 64 bit And so on. . . Problem I hooked this beast up to our home theater and settled in for a great gaming season only to realize a couple of drawbacks: It's hard to accurately wax bad guys using a keyboard in your lap whilst reclined on your couch (and using a wireless keyboard). It's hard to read the text on the screen (i.e. menus, etc). I find that a 1:1 ratio (screen diagonal inch to inch away from screen) is optimum, but using the home theater, it's more like 1:3 which has me squinting unless I sit on the coffee table. The wife always seems to want the TV the same time I do and, unfortunately "Real Housewives of Beverly Hills" and Battlefield BC don't mix. I am losing the battle in the home theater room, but the PC has to stay there (long story). So, this leaves me with the option of playing in my home office which is about 30 feet away from the home theater. I am a software developer so I have a pretty decent set up in my office--multiple 1080p monitors, HP Envy 17 which can run games like Crysis in 720p with out stammering too much. Also, I can game very comfortably at my desk in the office. Still, even though the set up in my office can run games well enough, I don't want to regress to that when I have worked YEARS for an awesome gaming PC that can run everything on ultra high settings. My Question What are my options for running my games on the beastly desktop in the Home Theater, but physically playing in my office about 30 feet away? A really long HDMI cable? LAN/RDC? Details that May Help We have an open crawlspace so running cable from HT room to office is no problem. I already have networked the house with a LAN Any help is GREATLY appreciated. Thanks, Matt

• what is Remote Desktop Services in Windows Server 2008 R2 all about?

  - by fejesjoco

  Seriously, I'm lost in all that sales mumbo-jumbo. Let's say I want 1 or 2 users to be able to remotely log on to a server, run Word, Visual Studio, Firefox, and whatever. Do I gain anything at all if I install Remote Desktop Services? Or do I just install Desktop Experience feature pack, enable remote desktop and voila, nobody will ever notice the difference? Here's what TechNet says about Remote Desktop Session Host: A Remote Desktop Session Host (RD Session Host) server is the server that hosts Windows-based programs or the full Windows desktop for Remote Desktop Services clients. Users can connect to an RD Session Host server to run programs, to save files, and to use network resources on that server. Users can access an RD Session Host server by using Remote Desktop Connection or by using RemoteApp. The good old simple remote desktop can also host a full Windows desktop for remote clients so that they can run programs, save files and do all that stuff. Why do they write about it like it's such a great new invention, besides that they want to sell it? RDSH doesn't seem all that different at all. What do I install when I install RDSH, since all those features are already there in Windows? What's even more confusing is that you need to take special care when you want to install applications to an RDSH so that they will be usable by many concurrent users. Why? All the modern applications install the program files in one directory, store some common settings in the ProgramData folder and the HKLM hive, and store user specific settings in the Users folder and the HKCU hive. They are designed to be usable by many users on the same machine. 2 or 2000 users can use them concurrently without any efforts. I can sign in with 2 users to a server with only remote desktop enabled, and both of us can run Word or anything without any problems, can't we? So what changes if I set RDSH to install mode, or what happens if I don't? Why is the feature to switch between install and execute mode there at all? Yes I know of some advantages in Remote Desktop Services, like there's no 2 user limit, it supports virtualization, video acceleration and stuff, it has a whole infrastructure with gateway, web access, connection broker, etc. But I don't need those, so if you take these away, how are these two technologies different? From the articles it seems like they are completely different technologies, whereas it looks to me that they are completely the same at the core, and Remote Desktop Services just adds some additional features, but doesn't reinvent anything.

• Looking for a NTP Server Software for Windows

  - by Simon

  I'm looking for a, preferably free, NTP Server for Windows Server 2003/2008. We have already tried the built in Windows Time Server, but our tests did show that it is not very accurate, we see time differences up to 500ms. The max time difference we can allow for our application is ~100ms. Now we have already used the Meinberg NTPd for Windows. It works great except we have one big issue with it: If there is a network connection problem between the client and server, the ntp server is in a panic state It won't give the client a new time until we restart the ntp service. This is a big issue which has caused us some trouble. It was working fine for months until there was a network problem we didn't notice, we only noticed it after a week when the time difference was already 30 sec. on the clients. So please suggest some alternative NTP Server for windows. I did Google but I get a lot of unrelated search results. Edit: So far the ntpd windows version was very accurate and I'd like to stick with it. The only problem is the "panic state" after a network disconnect. Maybe some knows here what the cause of this is and how to fix it. Also, I forgot to mention that we have a server/client setup like this: Server1 -- Server2 -- Server3 -- Client1 -- Client2 -- Client3 So Server2 gets its time from Server1, Server3 gets its time from Server2, and the Clients get their time from Server3. Also, there are clients connected directly to Server2. It is important that all Servers and Clients have the exact same time (within ~100ms) Now there was a network problem with Server3 and its clients. The servers run the ntpd port for Windows, which acts as NTP server and client. The clients have Dimension4 as NTP client. After the network problem, the error message in D4 was something like this (out the top of my head, don't have the exact error message): Server response: The server is in a panic state (could not sync clock) I read through the ntpd docs, and the only mention of "panic" is when the time difference is 10000 seconds which will cause to exit the ntpd server but this was not the case. Also there is a "-g" command line switch to disable the panic exit, but it is already set by default. Any ideas what could cause the panic state and how to get rid of it next time?

Once I set that up and downloaded this fiddler helper as a firefox add-on, it worked fine. When I turn on fiddler, it automatically takes my proxy setting from no proxy (default) to the 127.0.0.1 with Port 8888 set up. It worked fine until my computer detected this virus. Anyway, hopefully I've given you sufficient information to offer me your best advice here. Like I said, Spydoctor says the bad stuff is gone, so maybe the rogue program made some type of change in my fiddler that I could just reset or uncheck or something like that? Or will I need to completely remove fiddler and those dat files and rar files I downloaded? Any help would be greatly appreciated. Thanks for your time.

• Intel RST accidentally selected wrong drive as system drive -- how to fix?

  - by Sean Killeen

  Question / TL;DR If Intel RST has marked a drive other than my RAID set as the system drive, how can I get it so that the RAID set is now seen as the system drive, and catch it up to my drive now? What Happened NOTE: Some perhaps unwise decisions are ahead. This is as best as I can recall the order of things. I had a 2x1TB RAID1 config. I bought the drives around the same time, and they started to die around the same time. I replaced 1st drive with a 2 TB drive before the other one's SMART errors got more serious. I waited for the RAID to replicate, then replaced the 2nd drive with a manufacturer's replacement. I got a second manufacturer's drive replacement and used it as a spare. so I now I had a 1TB/2TB drive in a RAID1 and another 1TB as a spare. The 1TB drive in the replacement set was bad from the manufacturer. Rather than mess with their refurbished stuff, I bought another 2 TB drive an upped the config to a 2x2TB RAID1 with the other, functioning manufacturer's drive as a spare. I made the mistake of trying to bring the other drive online to clean it out and the signatue clash killed my machine. When the machine rebooted, that drive was marked as the system drive. So, I have a 2x2TB RAID1 that is apparently offline, and 1 spare 1 TB refurbished drive that everything is being run from. Not a great idea. Options I'm considering Bring the 2x2TB drive back online, and then unplug the spare until I can format it in another system. This would involve some data loss, but the more I think about it, I actually think I haven't modified any data that isn't backed up or synced somewhere (go me!) Anything that isn't is likely trivial, enough that I'm willing to take the risk. One downside here is that if the 2 TB doesn't have data on it for some reason, I could be screwed trying to put the other drive back in, no? Try to somehow get the RAID1 updated with the data from the current system drive. Option 3?

• XP shared folders not accessible after BIOS changed

  - by stijn

  Here's what worked for over a year: PC A runs Windows 7, PC B runs Windows XP. Both are on the same subnet behind a router. A uses user account X, but logs in to PC B using the Administrator account. PC B is a Dell Precision 470. A known problem with these is that sometimes when plugging in their power cable they somehow loses all BIOS settings. This happened yesterday. After this happens Windows won't boot, because the default BIOS setting is 'RAID ON' while there is no RAID configured. No problem though, changing the BIOS settings to 'RAID OFF' makes it boot without problems. Note that in the meantime, nothing config-related was changed on machine A. It wasn't even on. Indeed after doing this, everything is fine. Everything includes all normal operations, remote desktop from PC A to PC B, running Synergy between A and B, accessing shared folders from B to A. But accessing the shared folders on B from A does not work any more. I tried pretty much everything I found via Google (fiddling with policies/registry kes/...) but no avail. > ping -a 192.168.2.2 Pinging A [192.168.2.2] with 32 bytes of data: Reply from 192.168.2.2: bytes=32 time<1ms TTL=128 > net view \\192.168.2.2 System error 5 has occurred. Access is denied. > net use /persistent:no K: \\A\myshare /user:A\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:192.168.2.2\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:USERNAME PASSWORD System error 86 has occurred. The specified network password is not correct. A solution to this would be great: I haven't been able to do any work since yesterday ;] update after taking the hard drive out of B and putting it in another Precision 470 with almost exactly the same hardware (at first sight, only the video card differs) the shared folders work.. Putting the disk back into A, same problem remains. Why does this depend on hardware, and more important, on which hardware?

• Why is mount -a not mounting fuse drive properly when executed remotely (via Fabric)?

  - by Jim D

  This is a weird bug and I'm not sure where it's coming from. Here's a quick run down of what I'm doing. I'm trying to mount a FUSE drive to an Amazon EC2 instance running Ubuntu 10.10 using s3fs (FUSE over Amazon). s3fs is compiled from source according to the instructions etc. I've also added an entry to /etc/fstab so that the drive mounts on boot. Here's what /etc/fstab looks like: # /etc/fstab: static file system information. # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 LABEL=uec-rootfs / ext4 defaults 0 0 /dev/sda2 /mnt auto defaults,nobootwait,comment=cloudconfig 0 2 /dev/sda3 none swap sw,comment=cloudconfig 0 0 s3fs#mybucket /mnt/s3/mybucket fuse default_acl=public-read,use_cache=/tmp,allow_other 0 0 So the good news is that this works fine. On reboot the connection mounts correctly. I can also do: $ sudo umount /mnt/s3/mybucket $ sudo mount -a $ mountpoint /mnt/s3/mybucket /mnt/s3/mybucket is a mountpoint Great, right? Well here's the problem. I'm using Fabric to automate the process of building and managing this instance. I noticed I was getting this error message when using Fabric to build s3fs and set up the mount process: mountpoint: /mnt/s3/mybucket: Transport endpoint is not connected I isolated it down the the problem and built a fabric task that reproduces the problem: def remount_s3fs(): sudo("mount -a") Which does: [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] Executing task 'remount_s3fs' [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] sudo: mount -a [And yes, I was sure to unmount it before running this task.] When I check the mount using mountpoint I get: $ mountpoint /mnt/s3/mybucket mountpoint: /mnt/s3/mybucket: Transport endpoint is not connected Done. But if I run sudo mount -a at the command line, it works. Hrm. Here is that fab task output again, this time in full debug mode: [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] Executing task 'remount_s3fs' [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] sudo: sudo -S -p 'sudo password:' /bin/bash -l -c "mount -a" Again, I get that transport endpoint not connected error. I've also tried copying and pasting the exact command run into my ssh session (i.e. sudo -S -p 'sudo password:' /bin/bash -l -c "mount -a") and it works fine. So...that's my problem. Any ideas?

• Linux per-process resource limits - a deep Red Hat Mystery

  - by BobBanana

  I have my own multithreaded C program which scales in speed smoothly with the number of CPU cores.. I can run it with 1, 2, 3, etc threads and get linear speedup.. up to about 5.5x speed on a 6-core CPU on a Ubuntu Linux box. I had an opportunity to run the program on a very high end Sunfire x4450 with 4 quad-core Xeon processors, running Red Hat Enterprise Linux. I was eagerly anticipating seeing how fast the 16 cores could run my program with 16 threads.. But it runs at the same speed as just TWO threads! Much hair-pulling and debugging later, I see that my program really is creating all the threads, they really are running simultaneously, but the threads themselves are slower than they should be. 2 threads runs about 1.7x faster than 1, but 3, 4, 8, 10, 16 threads all run at just net 1.9x! I can see all the threads are running (not stalled or sleeping), they're just slow. To check that the HARDWARE wasn't at fault, I ran SIXTEEN copies of my program independently, simultaneously. They all ran at full speed. There really are 16 cores and they really do run at full speed and there really is enough RAM (in fact this machine has 64GB, and I only use 1GB per process). So, my question is if there's some OPERATING SYSTEM explanation, perhaps some per-process resource limit which automatically scales back thread scheduling to keep one process from hogging the machine. Clues are: My program does not access the disk or network. It's CPU limited. Its speed scales linearly on a single CPU box in Ubuntu Linux with a hexacore i7 for 1-6 threads. 6 threads is effectively 6x speedup. My program never runs faster than 2x speedup on this 16 core Sunfire Xeon box, for any number of threads from 2-16. Running 16 copies of my program single threaded runs perfectly, all 16 running at once at full speed. top shows 1600% of CPUs allocated. /proc/cpuinfo shows all 16 cores running at full 2.9GHz speed (not low frequency idle speed of 1.6GHz) There's 48GB of RAM free, it is not swapping. What's happening? Is there some process CPU limit policy? How could I measure it if so? What else could explain this behavior? Thanks for your ideas to solve this, the Great Xeon Slowdown Mystery of 2010!

  I've two ASAs 5515 connected in failover Active/Stand by (on Gi0/5) My two ASAs are connected to two Switch ProCurve 2920 to have HA if something happens. So I plug something like that (don't pay attention to the arrows) : So one the ASA, I created a Port-Channel like that : interface GigabitEthernet0/0 nameif outside security-level 0 ip address 192.168.1.3 255.255.255.0 standby 192.168.1.4 ! interface GigabitEthernet0/1 speed 1000 duplex full channel-group 1 mode passive no nameif no security-level no ip address ! interface GigabitEthernet0/2 speed 1000 duplex full channel-group 1 mode passive no nameif no security-level no ip address ! interface Port-channel1.1 vlan 1 nameif inside security-level 100 ip address 192.168.8.1 255.255.255.0 standby 192.168.8.2 ! interface Port-channel1.10 vlan 10 nameif guest security-level 50 ip address 172.16.100.2 255.255.255.224 standby 172.16.100.3 ! interface Port-channel1.16 vlan 16 nameif dmz security-level 50 ip address 192.168.16.1 255.255.255.0 standby 192.168.16.2 On the switch, I created a trunk LACP capable with the port 1 and 2 on each switch, force the speed to 1000 and put the port un full duplex mode. BUT this is not working... I tried many things and I can't make it work. In this configuration, I can't ping anything between my ASA and my Switch (or any object connected).

• Active Directory Corrupted In Windows Small Business Server 2011 - Server No Longer Domain Controller

  - by ThinkerIV

  I have a rather bad problem with my Windows SBS 2011. First of all, I'll give the background to what caused the problem. I was setting up a new small business server network. I had my job about finished. The server was working great, all the workstations had joined the domain, and I had all my applications and data moved to the server. I thought I was done. But then it happened. I tried adding one more computer to the domain, and to my dismay the computer name was set to the same name as the server. Apparently when a computer joins a domain with the same name as another machine that is already on the domain, it overrides the first one. For normal workstations, this is not a big deal, you just delete the computer from AD and rejoin the original computer to the domain. However, for a server that is the domain controller it is a whole different story. Since the server got overridden in AD, it is no longer the domain controller. The DNS service is not working and all kinds of other services are failing also. So the question is, what are my options? I am embarrassed to admit it, but since this is a new server one thing I did not have setup yet was backup. So I have no backups to work from. I am worried that things are broken enough that I might need to do a reinstall. However, I already have several days worth of configuration into this server, so I would obviously prefer if there was a fix that would prevent me from needing to do a reinstall. All the server components are there and installed correctly, but they are misconfigured (I think it is basically just Active Directory). So I have the feeling that if I did the right thing I could solve the issue without a reinstall. Is there anyway to rerun the component that installs the initial configuration to "convert" the base windows server 2008 r2 install into a SBS? In other words in the program files folder there is an application called SBSsetup.exe, is there anyway to rerun this and have it reconfigure AD, etc. to work with SBS? Any insight will be greatly appreciated. Thanks.

• OS X server large scale storage and backup

  - by user135217

  I really hope this question doesn't come across as trolling or asking for buying advice. It's not intended. I've just started working for a small ad agency (40 employees). I actually quit being a system administrator a few years ago (too stressful!), but the company we're currently outsourcing our IT stuff to is doing such a bad job that I've felt compelled to get involved and do what I can to improve things. At the moment, all the company's data is stored on an 8TB external firewire drive attached to a Mac Mini running OS X Server 10.6, which provides filesharing (using AFP) for the whole company. There is a single backup drive, which is actually a caddy containing two 3TB hard drives arranged in RAID 0 (arrggghhhh!), which someone brings in as and when and copies over all the data using Carbon Copy Cloner. That's the entirety of the infrastructure, and the whole backup and restore strategy. I've been having sleepless nights. I've just started augmenting the backup process with FreeBSD, ZFS, sparse bundles and snapshot sends to get everything offsite. I think this is a workable behind the scenes solution, but for people's day to day use I'm struggling. Given the quantity and importance of the data, I think we should really be looking towards enterprise level storage solutions, high availability and so on, but the whole company is all Mac all the time, and I cannot find equipment that will do what we need. No more Xserve; no rack storage; no large scale storage at all apart from that Pegasus R6 that doesn't seem all that great; the Mac Pro has fibre channel, but it's not a real server and it's ludicrously expensive; Xsan looks like it's on the way out; things like heartbeatd and failoverd have apparently been removed from Lion Server; the new Mac Mini only has thunderbolt which severely limits our choices; the list goes on and on. I'm really, really not trying to troll here. I love Macs, but I just genuinely don't know where I'm supposed to look for server stuff. I have considered Linux or FreeBSD and netatalk for serving files with all the server-y goodness those OSes bring, but some the things I've read make me wonder if it's really the way to go. Also, in my own (admittedly quite cursory) experiments with it, I've struggled to get decent transfer speeds. I guess there's also the possibility of switching everyone off AFP and making them use SMB or NFS, but I understand that this can cause big problems with resource forks and file locks. I figure there must be plenty of all Mac companies out there. If you're the sysadmin at one, what do you use? Any suggestions very gratefully received.

• long access times and errors in iis application

  - by Jens Olsson

  Hi, I am having an issue with an IIS application (details of environment at the end of the message). The web site works great most of the time and I cannot reproduce any error in our test system. On the live system however with on averare of 5-15 requests per second I have a problem with that some requests (about 0.05%) will take over 300 seconds to complete. The other requests complete withing 5-10 seconds. It seem like if all the errornous requests end up with a Timer_EntityBody error in the error log. I have never seen this as an end user but I guess that they will receive some kind of error message. I am trying to find out what can be causing this errornous behaviour. Any ideas are welcome. I have read something about that there can be an MTU issue if ICMP and MTU protocols are blocked in the firewall. Does that sound reasonable? I have also read about updating to IIS 7 should do the trick. Does it sound reasonable? I think that the problem has another cause but I have no idea of what. I have tried running hte perormance monitor, monitoring for database locks and active transaction counts. I can see some of these in the perfmon log for the MSSQL server (another machine) for example: Active transactions is sometimes peaking and sometimes for long periods Lock waits per seconds is sometimes peaking Transactions per second is sometimes peaking Page IO Latch wait is sometimes peaking Lock wait time (ms) is sometimes peaking But I cannot see that any of these correlate to the errors in the IIS error log. On the IIS server machine I can also see with perfmon that some values peak a few times during a day: Request execution time Avg disk queue length I can neither see that any of these correlate to the errors in the IIS error log. In the below code I have anonymized by replacing some parts with HIDDEN The following can be seen in the access log 2010-10-01 08:35:05 W3SVC1301873091 **HIDDEN** POST /**HIDDEN**/Modules/BalanceModule.aspx - 80 - **HIDDEN** Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729;+.NET4.0C;+.NET4.0E) ASP.NET_SessionId=**HIDDEN** 400 0 64 0 2241 127799 At the same time the following can be seen in the error log: 2010-10-01 08:35:05 **HIDDEN** 1999 **HIDDEN** 80 HTTP/1.0 POST /**HIDDEN**/Modules/BalanceModule.aspx - 1301873091 Timer_EntityBody Test+Pool I can tell the following about the environment: Server: Windows Server 2003 x64 SP2 running on VMWare HTTP Server: IIS v6.0 with ASP.NET 2.0.50727 Antivirus: Trend Micro OfficeScan (Is it a good idea to have this on a server?)

• How to Setup Ubuntu Mail Server with Google Apps?

  - by Apreche

  I have a domain, let's call it foobar.com. All of the MX records for foobar.com point to Google's mail servers because I am using Google Apps for your domain to manage it. It's great because everyone gets all the advantages of GMail, but our e-mail addresses aren't @gmail.com. I also have a server. Primarily, it's a web server, but it also serves other things. One of the things it serves is the web site for foobar.com and also sites for various virtual hosts such as shop.foobar.com and forum.foobar.com. The server is running Ubuntu 8.04, because I like using LTS releases in production. The thing is, there are various applications running on the server that need the ability to send out emails. Various applications, like the cron jobs, send me e-mails in case of errors. Some of the web applications need to send e-mail to users when they forget their passwords, to confirm new registered users, etc. Lastly, it's nice to be able to send e-mail from the command line using the mail command, or mutt. How can I setup the mail on the web server to go through the Google apps mail servers? I don't need the web server to receive mail, though that would be cool. I do need it to be able to send mail as any legitimate address @foobar.com. That way the forum application can send mails with [email protected] in the from field, and the ecommerce application will have [email protected] in the from field. Also, by sending the mail through the Google servers, we can avoid a lot of the problems with the e-mails being blocked by various spam filters on the web. Google's SMTP servers are trusted a lot more than mine would be. I'm pretty good with administering Linux systems, but I am absolutely brain dead when it comes to e-mail. I need step by step directions from beginning to end on how to set this up. I need to know every thing to install, and every single change to the configuration files that is necessary. I have tried following various howtos and guides in the past, but none of them were quite right. Either they didn't work at all, or they offered a configuration that is not what I wanted. Please help. Thanks.

• Deployment/provisioning tool for commercial applications (not developed in-house)

  - by mfinni

  I help manage a few hosted commercial applications, and we have a lot of manual processes involved when doing new customer-instance deployments into the shared (multitenant) environment. Allow me to describe the most relevant features, and then we can talk about the tools. We have an application on AIX, that requires dozens of changes to config files (some plain text, some XML) as well as a good number of commands to be run on multiple servers - some to start the new instance, some to restart our shared authentication and reporting engines, etc. The config changes follow templates, of course. The servers in question will also depend on the initial conditions specified by the implementer/deployer - we may choose to deploy a given customer to our servers in Europe, or one set of servers may be active-active whereas a different set of servers is active-passive - in short, there's a lot of complications. We have another application that run on IIS 6 and SQL. The DBAs don't want any automation of the SQL components and that's fine with me, but automating the IIS bit would be great. For a new customer instance, we make a filesystem copy of a template Virtual Directory target named after the new customer, make a new AppPool to match, edit a VirDir template .xml file to replace the filepaths and AppPool names with the new ones, and then make a new VirDir from the modified template XML to point to the new filesystem folder and app pool. For the first case, something like ControlTier or Chef might be good. For the second, the new(ish) Web Deploy from MS would probably do a good job. Has anyone used these tools or others to do something similar for applications? More of a nice-to-have, not a fixed requirement - Has anyone used anything that works on both platforms? I'm looking for something free, because the official word is that within a year, we will have whatever HP has renamed the OpsWare suite, which should be able to do stuff like this. Edit - based on someone's suggestion, looking at CFengine for the AIX application, it doesn't seem to address my pain. The problem isn't keeping a given config synced across dozens of servers, we have rsync for that. The problem is that onboarding a new customer instance touches dozens of files, putting pieces of the same or similar information into them - some are new stanzas in existing files, some are new files, and some are new directories. This is a several-hours-long process that is also error-prone because it's mostly done by hand. I guess I'm looking for config-file generation and management. I have built a small Perl script to do something similar for a much smaller case - it binds a CSV file into variables, and then does a copy-and-search-and-replace from a set of template config files. I could probably do the same here.

• What Are All the Variables Necessary to Create Blackbox Logs for Nginx?

  - by Alan Gutierrez

  There's an article out there, Profiling LAMP Applications with Apache's Blackbox Logs, that describes how to create a log that records a lot of detailed information missing in the common and combined log formats. This information is supposed to help you resolve performance issues. As the author notes "While the common log-file format (and the combined format) are great for hit tracking, they aren't suitable for getting hardcore performance data." The article describes a "blackbox" log format, like a blackbox flight recorder on an aircraft, that gathers information used to profile server performance, missing from the hit tracking log formats: Keep alive status, remote port, child processes, bytes sent, etc. LogFormat "%a/%S %X %t \"%r\" %s/%>s %{pid}P/%{tid}P %T/%D %I/%O/%B" blackbox I'm trying to recreate as much of the format for Nginx, and would like help filling in the blanks. Here's what Nginx blackbox format would look like, the unmapped Apache directives have question marks after their names. access_log blackbox '$remote_addr/$remote_port X? [$time_local] "$request"' 's?/$status $pid/0 T?/D? I?/O?/B?' Here's a table of the variables I've been able to map from the Nginx documentation. %a = $remote_addr - The IP address of the remote client. %S = $remote_port - The port of the remote client. %X = ? - Keep alive status. %t = $time_local - The start time of the request. %r = $request - The first line of request containing method verb, path and protocol. %s = ? - Status before any redirections. %>s = $status - Status after any redirections. %{pid}P = $pid - The process id. %{tid}P = N/A - The thread id, which is non-applicable to Nignx. %T = ? - The time in seconds to handle the request. %D = ? - The time in milliseconds to handle the request. %I = ? - The count of bytes received including headers. %O = ? - The count of bytes sent including headers. %B = ? - The count of bytes sent excluding headers, but with a 0 for none instead of '-'. Looking for help filling in the missing variables, or confirmation that the missing variables are in fact, unavailable in Nginx.
