• How much of slow and fast flash memory a "flash memory" have? [migrated]

  - by gsc-frank

  Trying to know what is the best of my flash memories to use ReadyBoost I realize that I don't know how much of fast flash memory each of my flash drives have. One can read: In some situations, you might not be able to use all of the memory on your device to speed up your computer. For example, some flash memory devices contain both slow and fast flash memory, but ReadyBoost can only use fast flash memory to speed up your computer.

• Correlating %RDY in esxtop to CPU Usage in Guest

  - by Joe

  We recently upgrade a number of our VmWare hosts from 4.1 to 5.5 and noticed many of the VMs saw a step-wise jump in CPU usage as shown by the guest VM. We have not yet upgraded vmwaretools on any of the guests, but after investigating a bit more we saw many of these guests with a high %RDY value (50%) when viewed under esxtop. Unfortunately Linux (the guest) just shows "high CPU usage" without any insight into what portion of that is coming from %RDY (VmWare saying, "your guest is waiting on CPU from the host"). Are there any tools, /proc entries, etc. that can shed light on that information?

• USB ports not recognizing devices (vista)

  - by frank

  I'm trying to fix a problem on a Vista machine where all the USB ports seem to have power but they don't recognize devices plugged into them. It seemed to start after I plugged my mp3 player (sansa clip) into it and disconnect it. So it sounds similar to this article http://support.microsoft.com/kb/817900 but that was for XP. And I did try all the fixes (including the registry entry) but they did not help. It also sounds similar to this SU question 50110 but I don't think it is the mother board. I have see other places that suggest reinstalling the OS...but that seems like a last resort type of thing. I have also seen a suggestion of doing a system restore but not sure if that will help. Any ideas of what I can try?

• Have a Microsoft Exchange and Google Apps Email Running on the Same Domain

  - by Joe Sampson

  A company that I work for just acquired another company that was using Google Apps for it's email. We use Microsoft Outlook Exchange. The founders of the company (who are leaving) want to maintain a few email addresses on Google Apps for them to use over the next year. Does anyone know if it's possible to have just a few Google Apps email addresses working on a domain and the rest of the domain running on Outlook Exchange?

• Subversion Edge LDAP (require CAC Certificate not Username and Password)

  - by Frank Hale

  What I've Done: I've successfully installed and configured Subversion Edge 3.1.2 with LDAP support on a Windows 2008 server. I have configured LDAP users and am able to use LDAP credentials to work on repositories just fine. No issues whatsoever. Works great! What I Want To Do: I've been searching for several hours now in hopes to find some information on how to configure Subversion Edge server to require client certificates for user authentication against an LDAP environment. I have not found anything yet that gives me an indication of how to do it. I know there are SVN clients that are capable of prompting for CAC certificates but I cannot figure out how to set my server up to require it. NOTE: CAC authentication is already setup and working in the windows environment. Desired Outcome: When running svn commands that require authentication against my Subversion Edge Server I want it to prompt me for my CAC certificate instead of my Active Directory username and password. If anyone has any information on this I'd greatly appreciate it. EDIT: I'm still digging so if I find out anything I'll update this question with what I found.

• How can I sort my data while keeping paired rows together?

  - by Joe Lee Frank

  How can I pair two rows on a spreadsheet, so that for each data entry I can sort the matrix but the pair of rows moves as a single list of data, retaining the structure of the two rows? For example: Original entry A1,1 B1,1 C1,1 D1,1 A1,2 B1,2 C1,2 D1,2 A2,1 B2,1 C2,1 D2,1 A2,2 B2,2 C2,2 D2,2 Sorted reverse order A2,1 B2,1 C2,1 D2,1 A2,2 B2,2 C2,2 D2,2 A1,1 B1,1 C1,1 D1,1 A1,2 B1,2 C1,2 D1,2

• My PowerShell functions do not appear to be used

  - by Frank

  Hi there, I have a ps1 script in which I define 2 functions as such: function Invoke-Sql([string]$query) { Invoke-Sqlcmd -ServerInstance $Server -Database $DB -User $User -Password $Password -Query $query } function Get-Queued { Invoke-Sql "Select * From Comment where AwaitsModeration = 1" } I then call the ps1 file by typing it in (it's in a folder in the path, and autocompletion works) However, I cannot start using the functions. I am confused, because when I copy / paste the functions into the console, all is fine and they work. I also have a function defined in my profile, and it works. Where am I thinking wrong, why doesn't it work what I'm trying to do?

• Thunderbird 3.0 - how to use ESC key to close new mail window

  - by Joe Casadonte

  When reading an email, the ESC key can be used to close the window. This doesn't work when you're composing an email. Is there any way to do this? This happened in T-Bird 2.x, as well, but I'm looking for a 3.0 solution. Thanks!

• Do glue records in non-circular dns-lookups speed up domain resolution or not?

  - by Joe Hopfgartner

  Doing a lookup for my domain on http://www.intodns.com/ I noticed theese two messages: In Parent section: DNS Parent sent Glue The parent nameserver g.gtld-servers.net is not sending out GLUE for every nameservers listed, meaning he is sending out your nameservers host names without sending the A records of those nameservers. It's ok but you have to know that this will require an extra A lookup that can delay a little the connections to your site. This happens a lot if you have nameservers on different TLD (domain.com for example with nameserver ns.domain.org.) and in NS section: Glue for NS records INFO: GLUE was not sent when I asked your nameservers for your NS records.This is ok but you should know that in this case an extra A record lookup is required in order to get the IPs of your NS records. The nameservers without glue are: 109.230.225.96 84.201.40.52 You can fix this for example by adding A records to your nameservers for the zones listed above. I do perfectly understand that the primary objective of glue records is to resolve circular dependencies. The classic use case: my domain is example.com and I want to have the nameserver ns1.example.com. This will never work because i cannot know the ip of ns1.example.com if I don't fetch example.com and in order to do that I need to fetch it from ns1.example.com. To resolve this deadlock I add a glue record to ns1.example.com containing the ip adress of the nameserver, so this can work out. So this problem does not occour if the nameservers are in a different TLD than the domain i want to look up. But however to fetch the zone information from the nameservers I need to know their ip adress right? And in order to know that i need to fetch the zone the nameservers are in from their respective nameservers, right? (or rather my ISP needs to do that in the background) So an extra lookup that takes time? If I now have glue records, I know the IP adress right away without the need to look it up - so this should speed up the resolution of my domain, shouldnt it? However my DNS zone provider (tecserver.at) replied that this would make no sense because "we are not running ns1.ourdomain.com an ns1.ourdomain.com as authorative NS for ourdomain.com. This would be the only sense for glue records. Tecserver has a glue record because the NS for tecserver.at are ns1.tecserver.at and ns2.tecserver.at. Therefore a glue record is needed for resolution.

• Bash command substitution not working as expected

  - by Joe Fruchey

  I'd like to view the last few lines of a file, but I want the columns aligned. Basically, I want to disable wordwrap. This is straightforward with: tail $FILE | cut -c -80 But I'm trying to generalize my script for other users, and I'd like to cut to the actual terminal width, which I can get with: stty size | cut -d" " -f2 So I would imagine that I could just tail $FILE | cut -c -`stty size | cut -d" " -f2` but it doesn't work: stty: standard input: Invalid argument cut: invalid range with no endpoint: - Try `cut --help' for more information. (Same results with the 'new' $() expansion.) Now, if I echo it, it seems fine: echo cut -c -`stty size | cut -d" " -f2` cut -c -103 Am I just missing an escape char? Or is this somehow just not possible? Thanks.

• VBScript Capture StdOut from ShellExecute

  - by Joe

  I am trying to run the following code snippet as part of a tool to gather and log some pertinent system diagnostics. The purpose of this snippet is to gather the result of running the command: vssadmin list writers The snippet is as follows: ' Set WshShell = CreateObject("WScript.Shell") ' WScript.Echo sCurPath & "\vsswritercheck.bat" ' Set WshShellExec = WshShell.Exec("elevate.cmd cmd.exe /c " & sCurPath & "\vsswritercheck.bat") Set oShell = CreateObject("Shell.Application") oShell.ShellExecute "cmd.exe", sCurPath & "\vsswritercheck.bat", , "runas", 1 vsswriter = VSSWriterCheck Select Case oShell.Status Case WshFinished strOutput = oShell.StdOut.ReadAll Case WshFailed strOutput = oShell.StdErr.ReadAll End Select WScript.Echo strOutPut vsswriter = strOutPut With the first code snippet (commented out) I can run the command and capture stdout from the batch file. In the second code snipped, I cannot capture stdout. I need to be able to run the batch script with Elevated permissions, so I am looking for a compromise between the functionality of the two. I cannot run the entire calling script in elevated mode due to restrictions from other pieces of functionality. I am looking for any ideas on how to add this output to my log as I am running out of options that are within the scope of basic scripts.

• Directly paste clipboard image into gmail message

  - by Frank Meulenaar

  I would like to be able to directly paste my clipboard image into a Gmail message. I could then just do alt-print screen, go to Gmail compose and press ctrl-v to embed a screenshot, for instance. I'm not talking about embedding a image from disk into my email; that's easily done. I want to skip the step where I have to save it to disk first. Eudora/Thunderbird support this. There's a program that does this, it's at picturepaste.com, but it's paid (and and the website uses Javascript for no obvious reasons). You can see the demo movie there if it's not clear what I would like. I would like to find a free alternative, or make one myself, but I have no clue how picturepaste works.

• Cheapest way to connect 20-24 Sata II HDDs in a budget storage server?

  - by Joe Hopfgartner

  I need to assemble a high density storage server for as cheap as possible. It's been a while for me and the last systems I integrated didn't even have Sata yet... During my Research I of course stumbled about Nexsan SATA Beast, the BackBlaze storage Pods as well as some ridiculously overpriced HP Proliant or Dell storage solutions. Finally I choose Norco cases as the way to go. My eye is set on the RPC-4020, which is a 4U 19" Rackmount case with 20 Hot Swap 3.5" SATA/SAS Hdd trays (Backplanes included) and room for two 2.5" OS drives as well as a Slim Line CD-Rom. The backplanes connect with a single SATA port for each drive, so there are 20 internal SATA ports to to be connected. They also have redundant power ports which I think is quite nice. The cheapest price I have found is 290$ + 40$ shipping. In europe the cheapest unfortunately is 370€ (500$) + 40 € shipping... A nice alternative would be the RPC-4224 which has SFF-8087 Mini SAS connectors that bundle 4 SATA trays each. But it doesn't seem to be available in Europe (where i am) anywhere. So here comes my problem: What Mainboard/Controller to choose to connect them for as cheap as possible while still having nice data rates? I have to say that the server is intended as a Storage server with 1gps connectivity and the data transfer will be distributed very evenly across all drives. I also don't require any raid functionality. This is all done at application level, I just need JBOD. So for example if I go for the RPC 4020 Model I need to connect 20 Storage + 1 OS + 1 CDROM Sata ports. I searched a bit and stumbled across this very low priced controller: http://www.intel.com/products/server/raid-controllers/SASWT4I/SASWT4I-overview.htm They sell it for 115 € here and the specs say it can control up to 122 hard discs and has 4 Mini SAS connectors. So I would use 4 Mini SAS 36pin - 4 SATA 7pin cables to connect 4 SATA drives to each port and choose a Mainboard taht has 6 SATA on board (for example this one) and hurray, I can connect my 22 SATA devices for as low as about ~ 220 EUR (cpu, ram, psu, case not counted) Question: WOULD THAT WORK? And if not, why? 2nd Question: If I go for the 4220 or 4224 Model, I have internal Mini SAS connectors. Am I right in assuming that the backplane than acts as a "SAS Expander"? And can I just plug these SAS connectors into any SAS port I can find on my controller / mainboard or are there certain requirements? I know that SATA port multipliers only work with controllers that are ready for that. But isn't this expansion already implemented in the SAS standard? I am sorry that this is a very broad question, but I really spent the last week reading up and it seems to be not so clear! Especially all the controlling hardware specifications! 3rd Question: A lot of hardware specs feature "internal channels" and "internal connectors". The connecors are the physical numbers of places where I can plug a cable in. I got that. But are the "internal channels" always the maximum numbers of physical drives that can be used in the end? Or can I enhance this further by Expanders/Fanouts? 4th and last question: What do you think about the setup so far? Do you know any good alternatives? Maby I am completely going the wrong way and some DAS would be way better? Are there any comparable chassis available in europe? Please feel free to say whatever you think is relevant to the subject!

• How can I set up a local nameserver and modify DNS zones on it?

  - by Joe Hopfgartner

  This is a follow up to this question. I am having an issue with a Router that doesn't support hairpinning properly. See the link above for details. Now I want to set up a local DNS server that Hosts in our LAN can use to resolve public Hostnames (usual webbrowsing... ). Additionally I want to modify certain zones. In our LAN we have some servers serving resources that are not available in our public dns zone. We always have to configure our local LMHost files accordingly. For example we have a staging installation with a new feature running on a local Webserver, and we cannot access it with the IP directly because the website runs in a named virtual host container, we have to configure LMHost file to point some domain to the local IP address. And now we have also the Hair pinning issue. So my question is: What software can I use? Will bind do the job? I just need to insert some A entries into the zone. As easy as possible. We have local Linux/Ubuntu servers.

• How does one guarantee a remote client the same local IP address every time when connecting to a VPN?

  - by Joe Carroll

  I need to configure a VPN for secure remote access to a PACS serving DICOM radiological images. The DICOM standard requires that any clients accessing the PACS must be using a fixed IP address that is pre-registered in PACS. I haven't implemented this solution before and would appreciate any guidance. I believe it should be possible to use RADIUS on the server to authenticate users connecting to the VPN and with it assign each user their own specific local subnet IP address, which would be registered with the PACS. The server runs Windows Server 2003 R2 Enterprise Edition SP2 and the VPN device is a FortiGate 60C. The What would be the best and/or simplest way to set this up?

• Weighted round robins via TTL - possible?

  - by Joe Hopfgartner

  I currently use DNS round robin for load balancing, which works great. The records look like this (I have a ttl of 120 seconds) ;; ANSWER SECTION: orion.2x.to. 116 IN A 80.237.201.41 orion.2x.to. 116 IN A 87.230.54.12 orion.2x.to. 116 IN A 87.230.100.10 orion.2x.to. 116 IN A 87.230.51.65 I learned that not every ISP / device treats such a response the same way. For example some DNS servers rotate the addresses randomly or always cycle them through. Some just propagate the first entry, others try to determine which is best (regionally near) by looking at the ip address. However if the userbase is big enough (spreads over multiple ISPs etc) it balances pretty well. The discrepancies from highest to lowest loaded server hardly every exceeds 15%. However now I have the problem that I am introducing more servers into the systems, that not all have the same capacities. I currently only have 1gbps servers, but I want to work with 100mbit and also 10gbps servers too. So what I want is I want to introduce a server with 10 GBps with a weight of 100, a 1 gbps server with a weight of 10 and a 100 mbit server with a weight of 1. I used to add servers twice to bring more traffic to them (which worked nice. the bandwidth doubled almost.) But adding a 10gbit server 100 times to DNS is a bit rediculous. So I thought about using the TTL. If I give server A 240 seconds ttl and server B only 120 seconds (which is about about the minimum to use for round robin, as a lot of dns servers set to 120 if a lower ttl is specified.. so i have heard) I think something like this should occour in an ideal scenario: first 120 seconds 50% of requests get server A -> keep it for 240 seconds. 50% of requests get server B -> keep it for 120 seconds second 120 seconds 50% of requests still have server A cached -> keep it for another 120 seconds. 25% of requests get server A -> keep it for 240 seconds 25% of requests get server B -> keep it for 120 seconds third 120 seconds 25% will get server A (from the 50% of Server A that now expired) -> cache 240 sec 25% will get server B (from the 50% of Server A that now expired) -> cache 120 sec 25% will have server A cached for another 120 seconds 12.5% will get server B (from the 25% of server B that now expired) -> cache 120sec 12.5% will get server A (from the 25% of server B that now expired) -> cache 240 sec fourth 120 seconds 25% will have server A cached -> cache for another 120 secs 12.5% will get server A (from the 25% of b that now expired) -> cache 240 secs 12.5% will get server B (from the 25% of b that now expired) -> cache 120 secs 12.5% will get server A (from the 25% of a that now expired) -> cache 240 secs 12.5% will get server B (from the 25% of a that now expired) -> cache 120 secs 6.25% will get server A (from the 12.5% of b that now expired) -> cache 240 secs 6.25% will get server B (from the 12.5% of b that now expired) -> cache 120 secs 12.5% will have server A cached -> cache another 120 secs ... i think i lost something at this point but i think you get the idea.... As you can see this gets pretty complicated to predict and it will for sure not work out like this in practice. But it should definitely have an effect on the distribution! I know that weighted round robin exists and is just controlled by the root server. It just cycles through dns records when responding and returns dns records with a set propability that corresponds to the weighting. My DNS server does not support this, and my requirements are not that precise. If it doesnt weight perfectly its okay, but it should go into the right direction. I think using the TTL field could be a more elegant and easier solution - and it deosnt require a dns server that controls this dynamically, which saves resources - which is in my opinion the whole point of dns load balancing vs hardware load balancers. My question now is... are there any best prectices / methos / rules of thumb to weight round robin distribution using the TTL attribute of DNS records? Edit: The system is a forward proxy server system. The amount of Bandwidth (not requests) exceeds what one single server with ethernet can handle. So I need a balancing solution that distributes the bandwidth to several servers. Are there any alternative methods than using DNS? Of course I can use a load balancer with fibre channel etc, but the costs are rediciulous and it also increases only the width of the bottleneck and does not eliminate it. The only thing i can think of are anycast (is it anycast or multicast?) ip addresses, but I don't have the means to set up such a system.

• Excel Data Organization: Array Formulas? Tables? Named Range?

• How could Load average numbers from 'htop' exceed 100% CPU utlization?

  - by Joe Huang

  I use 'htop' to monitor my web server. It's recently quite loaded and the Load average is showing something like this: Load average: 3.10 2.56 1.63 I searched the web about these numbers and I found an article about it: http://blog.scoutapp.com/articles/2009/07/31/understanding-load-averages In the article, it says if I have 2 CPUs, 2.0 means 100% CPU utilization. And my VPS has two CPUs, so what does 3.1 mean? How could it exceed 100% CPU utilization? And from these numbers, does it mean I should be wary about the loading now? But the performance seems totally fine, and this is a managed VPS, the hosting company has not notified me any warning about it. During day time, Load average always show these high numbers... here is another snapshot while writing. Load average: 3.03 2.77 1.97 Load average: 0.41 1.29 1.60 <---- 5 more minutes later So I am wondering how much room left for this site to grow in current configurations? What kind of proactive actions I should take in advance? I don't want to wait until the server bursts. Thanks.

• Twitter Like Software for Corporations

  - by joe

  Is there microblogging software that companies can host internally? I think I remember Joel Spolsky mentioning that Fog Creek uses one. I can't remember what the name was or find what other software is out there. Does anyone have any ideas?

• Is there a lightweight MTA for Ubuntu 9.10 Desktop?

  - by Joe Casadonte

  I'm writing a Perl script to run as a cron job, and I want to email results & errors to a local account on the laptop. I'd like something that can talk SMTP (do any MTAs not adhere to SMTP?). I use Thunderbird 3, so I'll also need a POP/IMAP server (unless T-Bird can read straight from an mbox file; I'll have to check into that). No need for spam controls as I'll lock it down real tight, only accepting mail originating from the laptop itself. Thanks!
