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

  - by Jim

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

• Python coding with VLC player (quite a basic query I expect)

  - by Todd

  I'm fairly new to the whole coding realm so my knowledge is fairly limited, and I can't seem to find any basic tutorials on how to use scripts with VLC player. More specifically, the reason I'm asking here is because I stumbled across a post on this site about playing random clips from random videos on VLC player automatically. This is the forum post: Playback random section from multiple videos changing every 5 minutes My situation is similar to this lovely gentleman's was, though he clearly knows a lot more about coding than I do. In short, I'd like to copy this coding into a file of some sort and apply it to VLC player myself. Only I'm not sure what file type I'd have to save it as (I have Python by the way, and I tried saving it as a .py file but I didn't know if it was correct or where to go from there). Additionally, I'm not sure how to get VLC to "read" the script, so to speak - is there a specific location the file needs to be, and do I run the script from another program or through VLC? I'll reiterate that I'm relatively new to this, so if anybody would be so kind as to post a quick list of steps on how to save/place the file and use it with VLC player I really would appreciate it! P.S. I'm not computer illiterate, I'm fine with most programs and I'd understand if you just said things like "C:\Program Files (x86)\VideoLAN\VLC\plugins" or "in VLC, select Tools Plugins and extensions", I just wouldn't catch on to anything about adding a line of coding that does something without being told exactly what to write! Many thanks in advance! :) Todd

• how to remove an entry from system tray?

  - by altvali

  I've searched for an answer to this one and I haven't found one yet. How do i remove a single item from Windows' System tray? I'm targeting Windows XP. Edit: This is not about preventing items from starting up. I want the program to keep running, I just need another script/program to remove the first one's entry from system tray. Second Edit: One approach that I can think of is to try to hide the intended app by modifying registry keys. On several test machines I've found some registry entries that match the System tray information at HKEY_USERS\something-that-looks-like S-1-5-21-682003330-1563985344-725345543-1003\Software\Microsoft\Windows\CurrentVersion\Explorer\TrayNotify with BalloonTip, IconStream and PastIconsStream containing systray information. The important one is IconStream. On other machines, these are found at hkey_classes_root/local/setting/software/microsoft/windows/currentversion/TrayNotify I'm quite sure there's no danger in changing those specific registries, but I don't know how to write code for that. Can anyone help me with the code and with confirming if this has the desired effect of hiding the systray icon for an active program?

• How can I set Thunderbird's "Recipient" column to display my email address rather than a friendly na

  - by Howiecamp

  After configuring a single, unified Inbox within Outlook 2007 to unify multiple email accounts, I found Thunderbird 3's Smart Folder feature. It works great, providing individual inboxes for each of your email accounts and a unified inbox which provides a unified, virtual view of those other inboxes. Thunderbird is smart enough so what when I reply to an email addressed to a specific email account, the reply is "From" that email address. In order to know which inbound email was to which of my accounts, I added the "Recipient" column to the inbox Smart Folder: What's displayed in the Recipient column depends on how the sender/sender's email client addresses the email. If they send it to just "[email protected]" without specifying a friendly name, the Recipient column displays "[email protected]" and there's no ambiguity about which account the email was sent to. However, if the sender has me in their address book (likely stored with a friendly name), it will be addressed as "Howard Camp [[email protected]]" and then show in the Recipient column as "Howard Camp". The problem is that if someone emails me with a friendly name at another of my email accounts (e.g. "Howard Camp [[email protected]]", the Recipient column will also display "Howard Camp" and I can't tell which account it's to until I open the message and/or look at the details. How can I configure Thunderbird to always display my email address rather than the sender-specified friendly name in the Recipient column?

• Hiding a Website from Search Engine Bots and Viewers by Disabling Default VirtualHost

  - by Basel Shishani

  When staging a website on a remote VPS, we would like it to be accessible to team members only, and we would also like to keep the search engine bots off until the site is finalized. Access control by host whether in Iptables or Apache is not desirable, as accessing hosts can vary. After some reading in Apache config and other SF postings, I settled on the following design that relies on restricting access to only through specific domain names: Default virtual host would be disabled in Apache config as follows - relying on Apache behavior to use first virtual host for site default: <VirtualHost *:80> # Anything matching this should be silently ignored. </VirtualHost> <VirtualHost *:80> ServerName secretsiteone.com DocumentRoot /var/www/secretsiteone.com </VirtualHost> <VirtualHost *:80> ServerName secretsitetwo.com ... </VirtualHost> Then each team member can add the domain names in their local /etc/hosts: xx.xx.xx.xx secrethostone.com My question is: is the above technique good enough to achieve the above said goals esp restricting SE bots, or is it possible that bots would work around that. Note: I understand that mod_rewrite rules con be used to achieve a similar effect as discussed here: How to disable default VirtualHost in apache2?, so the same question would apply to that technique too. Also please note: the content is not highly secretive - the idea is not to devise something that is hack proof, so we are not concerned about traffic interception or the like. The idea is to keep competitors and casual surfers from viewing the content before it's released, and to prevent SE bots from indexing it.

• error creating MS Exchange distribution list: Active directory response: 00000005: SecErr: DSID-031521D0

  - by BabakBani

  We've migrated a client from google apps to an MS Exchange 2010 SP2 on-premise setup. The setup /prepareAD went well, and the software was installed with the Administrator account. We've used the Exchange Management Console to setup mailboxes and had to google up the appropriate workarounds such as going into each users Advanced Security Settings and selecting "include inheritable permissions from this object's parents", and changing their logon-to from specific machines to "all computers" so that they can connect to Outlook Web Access, and in turn so their Outlook 2007-2010 clients can connect to Exchange. Sending and receiving emails are working well. Now that all this is in place, we can create Dynamic Distrubution Lists with no problem, but as soon as we try and create a DISTRIBUTION LIST, either in the EMC or the Exchange PowerShell, we get an error. As the error message in the powershell is more verbose, I include this if anyone can suggest how we remedy this: [PS] C:\Windows\system32new-DistributionGroup -Name 'projects' -SamAccountName 'projects' -Alias 'projects' Active Directory operation failed on DC.cppe.local. This error is not retriable. Additional information: Access is denied. Active directory response: 00000005: SecErr: DSID-031521D0, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0 + CategoryInfo : NotSpecified: (0:Int32) [New-DistributionGroup], ADOperationException + FullyQualifiedErrorId : 1EA5CD3E,Microsoft.Exchange.Management.RecipientTasks.NewDistributionGroup

• Are Windows Domain Service Accounts Really Necessary?

  - by Zach Bonham

  One of the biggest problems we have in automating application deployments is the idea that running IIS AppPools and Windows Services under domain service accounts is a 'best practice'. Unfortunately, this best practice sometimes causes deployment headaches in that either we need to provision a new domain level service account quickly, or once we have the account, we now need to manage the account credentials. I had a great conversation about not making domain level service accounts a requirement and effectively taking one of two approaches: Secure at the node level using machine account(domain\machine$) and add the node to appropriate ActiveDirectory/Sql groups/roles Create local app specific accounts on each machine (machine\myapp) and add that account to appropriate ActiveDirectory/Sql groups/roles (the password here can change per deployment, it doesn't need to be stored) In both cases, it seems that its easier to manage either adding an account to appropriate group/role, or even stand up new, local account, than it is to have to provision a new domain level account and manage those credentials. This would hopefully ease the management burden on ActiveDirectory, Sql Server and Operations teams as there would be no more password management. We've not actually been able to implement this in practice yet. I am coming from a development background, so I'm curious as to how many ways this approach could go wrong? Can we really get rid of domain level service accounts with this direction? I'd appreciate any thoughts from anyone who has taken this path! Thanks! Zach

• Will Parallel-port dongle work on USB-to-Parallel Adapter?

  - by Gary M. Mugford

  We have a niche program running on a Win2K laptop that uses a security dongle connected to a parallel port for authentication. The laptop is getting creaky and I spent a frustrating night last night shopping various websites for a new laptop that had a parallel port. Seems I'm about three years late [G]. The question I have, is, if I buy a new(ish) laptop and use a USB-to-Parallel Port adapter, will the security dongle work? I know I'm not being specific about the app, but it's one most people wouldn't have heard of anyways. I've been guessing the answer to my question is no, since the app won't know to send a request out to the non-existent port. But, if the process actually is that the dongle sends a message INTO the computer every now and then, then it might work. And, I'm not sure whether the dongle is only needed at program startup time or randomly. The dongle is a 'permanent' addition to the old laptop. This is all about the money. We can have a newly-updated version of the program (which won't add any features we need) for the princely sum of $2700. Or we can spend $500 on a refurbed laptop still running WinXP, add a 30 buck adapter and keep the same solid, stolid performance we've come to appreciate. But it all comes down to the dongle behaviour. Oh, and a dock won't work. The whole laptop issue is about moving about the various nooks and crannies of the building with laptop in hand. Thanks for any suggestions/guidance. GM

• How to find hidden/cloak files in Windows 2003?

  - by homemdelata

  Here is the point. I set Windows to display all the hidden files and protected operating system files but even after that, my antivirus (Kaspersky) is still getting a ".dll" file on "c:\windows\system32" saying it's a riskware 'Hidden.Object'. I tried to find this file everytime but it's not there. So I asked one of the developers to create a service that verifies the folder each 5 seconds and, if it founds the file, copies to another place. If it copies to another place with the same name and extension, I still can't find the file on the other folder but Kaspersky now founds both. If I keep the same name but with a different extension, like ".temp123", I still can't find the file. Lastly, I created an empty text file and renamed with the same name as the other one, the file just gone too. After all this research It's clear that every file with this same name on this specific server gets cloak, doesn't matter the file extension. I created a file with this same name on another server and nothing happens, the file is still there without problem. How can I found this kind of file? How can I "uncloak" it? How can I know what this file is doing?

• Best practices for settings for Oracle database creation

  - by Gary

  When installing an Oracle Database, what non-default settings would you normally apply (or consider applying) ? I'm not after hardware dependent setting (eg memory allocation) or file locations, but more general items. Similarly anything that is a particular requirement for a specific application rather than generally applicable isn't really useful. Do you separate out code/API schemas (PL/SQL owners) from data schemes (table owners) ? Do you use default or non-default roles, and if the latter, do you password protect the role ? I'm also interested in whether there's any places where you do a REVOKE of a GRANT that is installed by default. That may be version dependent as 11g seems more locked down for its default install. These are ones I used in a recent setup. I'd like to know whether I missed anything or where you disagree (and why). Database Parameters Auditing (AUDIT_TRAIL to DB and AUDIT_SYS_OPERATIONS to YES) DB_BLOCK_CHECKSUM and DB_BLOCK_CHECKING (both to FULL) GLOBAL_NAMES to true OPEN_LINKS to 0 (did not expect them to be used in this environment) Character set - AL32UTF8 Profiles I created an amended password verify function that used the apex dictionary table (FLOWS_030000.wwv_flow_dictionary$) as an extra check to prevent simple passwords.

• 1 document pending in printer queue in System Tray that won't go away

  - by White Phoenix

  Edit: I didn't want to do it, but I restarted my computer - cleared the problem right away. Though if I were running a Windows 2003/2008 server, I would hate to have to restart the domain controller just to get rid of this irritating problem. If I run into this problem again, I'm going to try that remove printer/reinstall printer thing. Thanks for your help @Psychogeek. Points for your attempt. Running Windows 7, 32-bit Professional. My printer is an HP OfficeJet Wireless 8500. It's connected to my network wirelessly through TCP/IP as a standalone device. I was having some print problems awhile back and had to do some print spooler stuff as part of my troubleshooting (stopping the Print Spooler service, clearing the print spooler files from C:\Windows\System32\spool\PRINTERS and then restarting the service). I've finally narrowed it down to it being application specific, so that's that. However, as a leftover from all that troubleshooting, my printer icon is stuck in the tray - when I mouseover the icon, Windows says that there is 1 document(s) pending for my username. However, when I open up that printer's queue, there's nothing in there. I restarted the Printer Spooler service and also checked C:\Windows\System32\spool\PRINTERS if there's anything in there - nothing. I did a quick Google search and an answer from one of those "reps" at the Microsoft Socialnet site says for me to uninstall and reinstall the printer. The funny thing is, when I send print jobs, they print just fine - that 1 mystery document stuck in queue isn't stopping anything from happening. Short of having to do that, are there any other quick troubleshooting steps I may be missing?

• Picking a linux compatible motherboard

  - by Chris

  Last time I bought a new computer (I build them myself) I got a motherboard that had really poor linux support for a long time. Specifically the audio. I had to wait months before the kernel supported the on board audio chipset. That is exactly the situation I'm trying to avoid this time around. I have some specific questions about "server motherboards" actually. I looked at a few models of server motherboards by intel, and some random models on newegg. I wasn't able to see much of a difference from regular desktop motherboard other than most had two sockets, and support for much more ram. These boards seem more popular with Linux users. Why? AMD and Intel both have server CPUs as well. Some question, what's the difference? To make this question more concrete, I was looking at this this motherboard. The main questions about it that I can't answer are: Can I get a motherboard without on board raid and audio? I wanted to get a hardware raid controller and a PCI audio card. I thought a server motherboard would be cheaper and not have these "extras", since who wants an audio card on a server? Where can I found out about Linux support for the components on this board? "Intel ICH10R", "Realtek ALC889", "Marvell 88E8056" I'm buying this computer to work as a Linux desktop for a lot of compiling, coding and audio/video work, but I don't want to rule out the possibility of installing windows and playing some games at one point. (even if the last game I got has been sitting in its box unopened for almost a year). Is it a good idea to buy a "server motherboard" and play games on it, or are desktop boards better value for this? The ultimate solution for me would be a motherboard that had GPL divers for onboard LAN, a single CPU socket, lots of PCI express and PCI. USB 3.0, and no fancy hard disk controllers since I'll be getting a separate one.

• exim4 redirect mail sent to *@domain1.example.com to *@domain2.example.com

  - by nightcoder

  Current situation: We have a VPS that hosts a website example.org. Exim is configured to work as a smarthost. All emails sent through exim are successfully relayed to another mail server (that is working on example.com). Goal: To forward mail sent to *@example.org to *@example.com, i.e. change the recipient's address from *@example.org to *@example.com.

• What is the collaborative screen shot/diagramming application recently featured on Hacker News and p

  - by wonsungi

  A few days ago, I saw this video for a screen capture application. I'm pretty sure I followed a link from Hacker News, possibly to a Life Hacker article. The video was very short, but demonstrated how the application could be used: The application was basically a movable/resize-able view port with a button. When the button is pressed, the contents of the view port are saved to an image (basically a screen capture.) The interesting thing is what you could do after that point. One of the specific examples from the video browsed to Google maps street view, grabbed a photo of an intersection, then scribbled notes about where to meet and where the restaurant was in colored "marker." Another example shown was grabbing a house layout from from CAD tool, then scribbling notes on it. The last part of the video showed several possible uses being scrolled through the application's view port. Now, it seemed it was very easy to share these images with other people because there was some type of integration, either with their own site and/or common social websites/chat services. The application was shown running on both Windows and Mac. edit: I think there was an iPhone app, as well. Anyone know what this application is? I tried searching Google, Hacker News, and Life Hacker already. It is not Jing.

• Creating a ssh tunnel to transfer files?

  - by Vincent

  For me, networks are a very "opaque" thing, and even with reading a lot of tutorial about SSH, I do not understand how to create a basic tunnel to transfer my files. The configuration is the following : My Computer --[Internet]--> Bridge Machine --[Local Network]--> Final Machine Currently I do the following : 1) Connect to the Bridge Machine with : ssh -X [email protected] 2) Connect to the Final Machine with : ssh -X username@finalmachine 3) I copy the address of files I need (for example .../mydirectory) 4) Then I deconnect from the finalmachine with : exit 5) I copy the files to the bridge : scp -r username@finalmachine:/.../mydirectory . 6) I deconnect from the bridge with : exit 7) I copy the files to my machine : scp -r [email protected]:/.../mydirectory . Which is quite complicated. My question is basic : how to simplify this using a SSH tunnel ? (and please explain me the signification of each command line you write, to understand what each line really do and to avoid to use it like a magical thing. Furthermore if some ports number are used, explain me if I can pick a completely random number or if I have to choose a specific one.)

• Browser history, by window

  - by Alex

  I use Chrome --but can switch to another browser if the feature I am about to describe is available. Browsing history, AFAIK in Chrome is sorted exclusively chronologically. Very often however, I will be working on a particular task on my laptop and have multiple (read: a lot) of tabs open in a single Chrome window for that task. Before finishing that task, I may need to work on something else --so I will open another window and minimize the other one, and start researching an entirely different issue. Over the course of a day, I may end up with 10-15 windows with many tabs each. This raises two issues: (a) memory usage and (b) quickly switching between the most relevant two or three windows. I solve these two problems like any regular guy probably would --closing windows. I want to be able to reopen specific windows that I have closed, such that the tabs that were open in that window at the time the window was closed will reopen. Ideally, closed windows will be sorted by the time they were closed and identified by the tabs that were open (even more ideally, I would be able to name these windows (contemporaneously or in the history menu)). Now that I describe this, what I am asking is: does any browser offer the ability to "save and close" windows? (This is distinct from an option to auto-restore tabs upon reopening the browser) Thank you.

• how to notify a program of another program? dll? directory? path?

  - by Brady Trainor

  I am trying to experiment with GNUS email in Emacs, in Windows (EDIT: x64 bit). I've got it to work in Ubuntu, but struggling with it in Windows. From http://www.gnu.org/software/emacs/manual/html_mono/emacs-gnutls.html#Help-For-Users I read in second paragraph: This is a little bit trickier on the W32 (Windows) platform, but if you have the GnuTLS DLLs (available from http://sourceforge.net/projects/ezwinports/files/ thanks to Eli Zaretskii) in the same directory as Emacs, you should be OK. I have downloaded and unzipped the gnutls-3.0.9-w32-bin package, but am not sure what to do with it. I have tried putting it in Program Files (x86), which is "the same directory as Emacs". I have tried putting it in the emacs-24.3 folder. I consider merging all the folders in between the two, but am hesitant as that seems a difficult troubleshoot attempt compared to my knowledge on these matters. I think Emacs needs to somehow see the gnutls binaries and/or dlls. My knowledge is limited on this. I've also struggled to understand PATHs for sometime now, and am not sure if that approach is relevant here. FYI, the emacs directory contains folders labeled bin, etc, info, leim, lisp and site-lisp. The gnutls directory contains folder labeled bin, include, lib and share. Hmm, now I'm finding lots of links on adding paths. Still, I'm skeptical that I would only add gnutls.exe path, as it seems the dlls are needed. Some additional data for Ramhound's first comment I have been attempting the (require 'gnutls) route. This seems to be the most relevant parts in the log: Opening connection to imap.gmail.com via tls... gnutls.c: [1] (Emacs) GnuTLS library not found Opening TLS connection to `imap.gmail.com'... Opening TLS connection with `gnutls-cli --insecure -p 993 imap.gmail.com'...failed Opening TLS connection with `gnutls-cli --insecure -p 993 imap.gmail.com --protocols ssl3'...failed Opening TLS connection with `openssl s_client -connect imap.gmail.com:993 -no_ssl2 -ign_eof'...failed Opening TLS connection to `imap.gmail.com'...failed I am not sure what "in stallion" means. Emacs seems to have installed itself in program files (x86), so I assume it is 32 bit. I can try and figure out how to double check, but did not realize I would get such fast response time, and am headed out right now. I will try merging the files later tonight?

• Only one domains not resolving via Windows DNS server at multiple locations, but is at others

  - by Brett G

  I'm having quite a weird issue. Had mail delivery issues to a specific domain. After looking closer, I realized that the DNS for that domain isn't resolving via the in-house Windows 2003 SP2 DNS server. C:\>nslookup foodmix.net Server: DC.DOMAIN.com Address: 10.1.1.1 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** Request to DC.DOMAIN.com timed-out (DC.DOMAIN.com and 10.1.1.1 are generic values to replace the actual ones) Even if I run this nslookup from the DC.DOMAIN.com server, I get the same result. However, all other requests are working as they should. I tried it on severs at completely separate organizations on different networks(Windows 2003 AD servers). The weird thing is some of these were having the same exact issue. However using public DNS servers work. I have tried clearing the DNS cache, restarting the server, restarting the services, etc. Nothing has worked. One weird event I noticed in the DNS Server Event Logs that might be related is an event ID of 5504 with the following description: The DNS server encountered an invalid domain name in a packet from 192.33.4.12. The packet will be rejected. The event data contains the DNS packet. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. In the data section below, I can see the following mentioned: ns2.webhostingstar.com Which happens to be the nameserver for the domain in question. Several discussion threads and a MS KB have pointed to disabling EDNS. I have done this via "dnscmd /config /enableednsprobes 0" and it has not fixed the issue.

• Datacenter IP Addressing and DNS Management

  - by user65248

  Hello everyone Basically we are setting up a small Datacenter, about 300 amps power and max 50 racks, Im saying these coz I wanna u imagine the size and requirements, I have studied networking mostly Microsoft and Windows based systems , but I cant get how the IP addressing and DNS management and configuration works in a Datacenter , and unfortunately I have to setup everything by myself but defe we will have some staff to do some job. Now my questions Datacenter IP Addressing Suppose we have got a block of 200 IP addresses from our ISP, How can I manage these block of IP addresses, is there any software out there to simplify this I heard that using DHCP server in a datacenter is not recommended, otherwise what would u say about MS DHCL server ofc considering we need to have backup serversin case of failur How can I assign a block of IPs to a specific rack, I know with different software and management its different but Im asking how it is done normally IP addresses are exposed to the whole network, what if a customer try to use an IP address and is not assigned to their server or rack , how can I prevent this or how can I track the IP usage DNS Management Im goin to setup at least two servers for our DNS servers, I know nothing about Datacenter DNS system, but I have configured DNS server in normal networks and also for webservers, Now I wanna know What exactly needs to be done for a DNS in a datacenter that is not done for normal networks. How can I configure PTR records why cant I configure PTR records on my webserver side DNS server and it should be done on datacenter DNS server , I mean what is the difference in DC DNS servers that allow us to to so , I know the question is very silly and simple but Im confused Is there any software outthere to allow doing the whole thing, I mean automatically add records to the DNS and also managin IP addresses !? Thanks in advance

• Body of email breaks distribution list in exchange?

  - by widgisoft

  Hi, I have a very odd problem that I'm not sure is a programming issue or a server issue :-p. Basically I'm sending an email to an exchange distribution list that includes a PHP stack trace; during certain faults the trace includes really high level information such as the machine's environment variables (during file reads, etc.). I went through a copy of the email line by line until the email sent and it appears the line: [SUDO_COMMAND] => /etc/init.d/httpd restart is the culprit. Adding a string replacement in before the email is sent allows a successful send. What I don't understand is WHY these stream of characters are causing the issue ONLY on the distribution email. If I send the email to myself as well, i.e. "[email protected]; [email protected]", then I get the email fine. Re-ordering the list doesn't make a difference the group never gets the email. Because the individual gets the email and not the group I'm assuming the fault is with exchange and some rogue filtering - I've gone through it with the sysadmins and there's no filtering of any sort on that group... so maybe it's a bug? I can't find anyone else having recorded this specific fault so I figured I'd open it here. For now I'm just not using the distribution list but it'd be nice to eventually find the solution. Many thanks, Chris

• Embedding a WMV file on the web via URL in a Powerpoint presentation

  - by Dave

  I've got a situation where I want to distribute a Powerpoint presentation to several people. I want to be able to embed several large videos in this presentation by linking to a URL, for the following specific reasons: the videos are highly confidential, and I would like to be able to delete them at some later date, but still allow them to see it in the presentation while it is online. I want to send the presentation via email (so it should be small), and put the links on a server with a faster upload speed Maybe I'd like to change the video at some point without changing the presentation One option that addresses #1 is to hook up a webcam and allow them to see video stream from the office, but our upload rate is too slow for this to be a viable option. I've tried embedding a video and giving Powerpoint the URL. It seems to work initially, because the first frame appears in my slideshow. However, when I play the slideshow, nothing happens. I looked at the network traffic on my computer, and nothing was getting downloaded from the remote server. Any suggestions on how to make this work, or how to at least satisfy the criteria listed above would be great!

• How do I only dp or do just the lines, not the entire block in Vim diff?

  - by hobbes3

  I'm currently using MacVim (Snapshot 64) "Split Diff by..." menu option. The file is Django's my settings.py from version 1.3.1 to a fresh file from version 1.4. (Open the image on a separate window/tab to enlarge.) I know two basic commands do to "obtain" (and replace) a block from the other side. dp to "put" (and replace) a block to the other side. But those two commands writes the entire block, which in MacVim is the purple highlights. If you look at the 2nd block, you can see that from line 2 and 3 only has 2 words that are different: mysite and hobbes3. I just want to replace per line not the entire block. So what is there a command to replace do do and dp per line as oppose to an entire block or do I have to manually type it out? Bonus question: I noticed that once I manually edit a block, I lose the purple highlighting. How do I "refresh" the diff again to include the highlights without reopening the file? Please try to keep the answers Vim-general as oppose to MacVim-specific. Thanks!

• PsExec and Remote Environment Variables, Logging, Etc.

  - by alharaka

  When I run PsExec on a remote computer, I always fall short of what I want. What I would like ideally in most situations is a) a log on an admin server where each individual log has the name of each the remote computer it was generated from (e.g. COMPNAME1.log, COMPNAME2.log, etc.) or b) a log file on each remote computer with whatever name I specify. When I try scenario (a), I use the following command. %SystemDrive%\path\to\psexec.exe @listofcomputers.txt -u DOMAIN\username cmd /c echo TEST >> \\server.company.tld\share\%computername%.log Problem is that it never works. All the computers just write to the log where %computername% is just the computer I execute PsExec from in my office. What I want are unique logs for each computer specific in the listofcomputers.txt that will correctly use the hostname from the remote environment variable without issue. Is that even possible? It does not seem to work for me. I tried this, and the syntax is clearly wrong. %SystemDrive%\path\to\psexec.exe @listofcomputers.txt -u DOMAIN\username "cmd /c echo TEST >> \\server.company.tld\share\%computername%.log" PsExec just fails saying the system file cannot be found (read: syntax fail). As for scenario (b), it appears to be a variation of a similar problem. When I run a command like this, it does not work. %SystemDrive%\path\to\psexec.exe @listofcomputers.txt -u DOMAIN\username "cmd /c echo %computername% >> \\server.company.tld\share\aggregated.log" Is there something I do not understand about remote path and environment variables with PsExec on the cmd.exe console (I have not even tried the dreaded PowerShell yet). I know such things work in a batch file (cmd /c \\server.company.tld\share\runthis.bat), but is there a reason it will not work when executing commands as arguments? I always need this, and can never get it!
