• Using client certificates with wget

  - by Doc

  I cannot get wget to use the client certificates. The documentation speaks about using the --certificate flag. The use of the certificate flag is clear, I set it to use the PEM version of the client certificate. But when I connect I get the following error: HTTP request sent, awaiting response... Read error (error:14094410:SSL routines: SSL3_READ_BYTES:sslv3 alert handshake failure; error:140940E5:SSL routines:SSL3_ READ_BYTES:ssl handshake failure) in headers. Giving up. ssl handshake failure means the client did not supply a correct client cert. Still the client cert I use, works in a browser. Note: When I disable client authentication on the server, wget can connect. Note: The use of curl is suggested, but I'd like to avoid the switch.

• Creating a Network link between 2 buildings

  - by Adam

  Hey My company needs to create a network link between two buildings. Currently we have a cat5e network in one building and would like to connect some computers(about 15) in our second building to the main network in the first building. The distance between the two buildings is 30 metres. The 30 metres means going through a wall from the first building. Going through the car park and then through a wall into the other building. We can run any cables through speed ramps and so we do not need to dig up the road! Also the second building does not have an Internet connection and so we have to create some sort of cable link so that they can share our Internet connection. Ideas? Should we just run cat5e? Should we run fibre? Should we run coaxial?

• Top/left edges of screen, in Virtualbox, act like bottom/right edges

  - by Ken

  I have Virtualbox running on Windows Vista, and Debian running inside Virtualbox. Everything's running great, for the most part. Everything looks correct. But when I'm in full-screen mode, the top edge seems to act (to the mouse) like it's the bottom edge, and the left edge seems to act like the right edge. For example, if I click in the middle of the desktop and drag left, as if to select some icons, when I hit the very leftmost pixel of the screen, the selection (but not the mouse pointer) jumps to the far right edge of the screen). For the left edge, it's not such a big deal, but not having the top edge is kind of annoying: it means I can't select things from the menu in my top panel by slamming the mouse against the top of the screen. Anyone seen this before? Is there some way to make this work? Thanks!

• Server 2008 Web Edition IIS6 SMTP conflict

  - by user219313

  I'm using IIS6 Manager to setup the SMTP service on Windows Server 2008 Web Edition. There seems to be a conflict (port 25?) which means that I cannot start and stop the Default SMTP server within IIS6. I can start and stop it with the services.msc snap in and this is reflected in state of the SMTP server in IIS6 manager. I'm worried that none of the settings I want to get at within IIS6 (logging, authentication etc..) are having any effect. None of these settings are available within IIS7 in Web Edition.

• Powershell overruling Perl binmode?

  - by hippietrail

  I have a Perl script which creates a binary file while scanning a very large text file. It outputs to STDOUT which I redirect in the commandline to a file. To optimize it I'm making changes then seeing how low it takes to run. On Linux for this I use the "time" command. On Windows the best way to time a program seemed to be to PowerShell's "measure-command". This seemed to work fine but I noticed the generated files were larger. On examination I found that the files generated from within PowerShell begin with a BOM and contain CRLF pairs! My Perl script has a "binmode STDOUT" directive and does work correctly in a normal dosbox. Is this a bug or misfeature in PowerShell or measure-command? Has it affected others creating binary files by means other than Perl? Googling hasn't turned anything up so far. I'm using Perl 5.12, PowerShell v1.0 and Windows XP.

• What does it mean to setup Postfix as "SMTP only"? [closed]

  - by BryanWheelock

  Possible Duplicate: What does it mean to setup Postfix as “SMTP only”? I am trying to setup Postfix a few different domains on a virtual host. I need to have email setup just to send out registration confirmations and new password requests. No one will have a mailbox on this server. It seems this means that I want to setup Postfix as SMTP only. I've also read about configuring Postfix null clients for simular needs. What is the difference between Postfix null client and SMTP only?

• (simple) linux HA with vmware vsphere?

  - by derhelge

  I hope my upcoming question is specific enough, and you are able and willing to support :-) We have several openSUSE VMs in an ESX-Cluster (three ESX-Servers) with an attached iSCSI-SAN. All of those Linux VMs are "single point of failure"-configured, which means in the case of a Web-Server: LAMP, storage, etc. everything on this machine. This was very simple and in case of a failure (in the last years: kernel panics or apache crashes) a simple reboot triggered by a script did it. But the problem is: How to upgrade/maintain the w(eb-)application or the underlying OS without downtime? This wasn't really managable and i did this in the early morning ;) How can i achieve a "simple" High-Availability Cluster now? I thought of: DRBD with heartbeat with 2 VMs. And for the storage a RDM (raw device mapped) LUN and change the read-write-permissions for both VMs. Is this a good idea? Anyone has a better solution?

• Can't find newer DLINK Router DIR-400 firmware

  - by Junior Mayhé

  If you're here, it means you also have a Dlink 400 router. I asked DLINK but they didn't answer my question. I asked DLINK support again, but this time no answer (2 weeks later). In DLINK FTP site there is no firmware for DIR-400. Past year, Googling around Russia, I found a FIRMWARE_DIR400_v1.02B03.bin. But I am trying to figure out if is there any update, a 1.03 version or superior. Can anyone tell me why DLINK doesn't show this firmware update on their site, and if this DIR-450 is compatible with mine?

• Memory consumption of each accept() call on server running on Windows 2008 [migrated]

  - by Atul

  I've written a simple and small server application on Windows 2008 that just accepts connections and does nothing else. I am doing memory footprint assessment of socket calls, What I found that each connection (after accept()) consumes at least 2.5 KB of memory. Interestingly, the memory is not consumed by the process that has accept() call but it consumed by a OS process. I believe it might be because of data structures being created inside OS for each connection. Now, I have two key questions: Is it possible by any means to reduce this memory footprint (by changing any parameters, configuration etc) ? If yes how ? (Because 2K for each connection would be too much if we planning server to accept millions of connections) If my server is intended to accept million connections, is it good idea to use Windows 2008 ? or shall I switch to some other OS? Please advice me.

• HDMI vs Component vs VGA vs DVI vs DisplayPort

  - by Nazadus

  What are the pros and cons of each of these different display adapters and cables? From what I can understand, HDMI offers the ability to send audio along the same cable as well as the ability to do progressive scan. I've Googled but I can't seem to find any real answers. Why would someone care to run 1280x1024 over HDMI or DVI instead of VGA? What about component? All I hear is one is digital and one is analog, but I can't find what that means from a feature/benefit stand point.

• Sonicwall settings for Polycom TFTP

  - by Michael Glenn

  I'm switching our VoIP phones (Polycom 301s and 501s) to our data network. They were previously segmented to their own network. This means disabling the DHCP on the Trixbox (Asterisk) server and configuring the Sonicwall TZ 210 DHCP to indicate that Trixbox is the TFTP server. The Polycom phones are stating "could not contact boot server". All phones are configured to TFTP and were confirmed working when previously using the Trixbox server for DHCP. Trixbox DHCP is now turned off. I've configured options 66(as String), 128(as IP) and 150(as IP) in DHCP and added them to a TFTP Option Group. I've enabled "Allow BOOTP Clients to use Range" for the Dynamic IP range and assigned the Option Group TFTP as the DHCP Generic Option Group. Any idea what I'm missing? Is there a separate tool to inspect the DHCP response to compare Trixbox to the Sonicwall?

• Mark as read on delete in Outlook?

  - by x3ja

  I'd like Outlook to mark any messages I delete to be marked as read. For bonus points, I'd like it to only do this on messages that I have opened/previewed before pressing delete since this means I've looked at the content and chosen to delete it. I know I can set it to mark as read after x seconds when I'm looking at it, that's not what I want. I also know that I can move off the message & back on to it or right click to mark as read - still not what I want. I'm using Outlook 2007 in case that matters. [Edit: I just found I can at least mark as read with a keyboard shortcut: Ctrl-Q, but again, it'd be nice to not have to do this. More shortcuts here.]

• Which are the non-x text editors in Powershell?

  - by Andrei T. Ursan

  Are there some editors like emacs, vi/vim, specifically for power shell, if so which are the best? I will have to do some work on windows and I need some unix productivity - which means for me shell + text editor with syntax highlighting (for python, java, c, c++), so which are my options? Edit: I'm looking for an alternative at vim or other unix editors, and cygwin is not an option. I just want from the command line to say texteditor_name file1, modify it, save it etc, and all of these to happen inside the terminal, not in another interface etc.

• SQL Server agent died

  - by Manjot

  3 SQL server agents stopped and didn't restart automatically untill we manually restarted them. SQL servers are on SQL 2005 X86 standard edition. The error message that was reported in Application log was: Faulting application sqlagent90.exe, version 2005.90.4211.0, stamp 49837478, faulting module kernel32.dll, version 5.2.3790.4480, stamp 49c51f0a, debug? 0, fault address 0x0000bef7. No errors were reported in SQL server logs or SQl agent logs. Does anyone know what this means? I tried to Google but no luck. Thanks in advance!

• Apache - Include conf Files Relative to ServerConfigFile (-f arg)

  - by Synetech inc.

  Hi, I want to use the -f command-line option for the Apache server so that I can store the conf files in a separate place (a data diectory) from the server binaries. The problem is that I use the Include directive to separate and organize the configurations, but when I use a command like Include "addons/SVN.conf", it fails because Apache looks for addons/SVN.conf in relative to the ServerRoot directory instead of the ServerConfigFile directory. I can work around this by using absolute paths (eg Include "e:\foo\bar\baz\Apache\conf\addons\svn.conf", but I don’t like that since it means I would have to change each and every Include directive if I move the conf folder as opposed to simply changing the -f option. Does anyone know of a way to get the Include directive to work relative to the conf file that Apache is passed. I tried Include "./addons/SVN.conf", but that too was relative to the ServerRoot. This forced relative-to-ServerRoot Include behavior kind of defeats the whole purpose of specifying an alternate config file to the one in ServerRoot/conf. Thanks.

• Making folder available offline - Access denied (Windows XP)

  - by alex

  I have a drive on a server called "filestore" This has a folder called "users" in here, theres is a "users" folder. In there are folders such as - jsmith, jblogs, abrown - which correspond to usernames of our active directory. When a user logs on, the H: drive is mapped to their above mentioned folder - for example //filestore/users/jsmith I am trying to make one of these folders available offline in Windows XP. when i do so, i get an access is denied error. according to this - http://support.microsoft.com/kb/275461 i need to make the root folder have read access to the users. This means, however, all the users will be able to get in all the folders (if they browse to //filestore/users/) How can I still achieve offline files for that particular users "h:" drive, and still have the other folders secured?

• How to add a 'second elbow' to an 'elbow arrow connector' in Powerpoint 2007?

  - by ricebowl

  I'm trying to put together a relatively complex flow-chart thing -as part of a University assignment (health-related, and gosh, does my university love all things Microsoft Office...). Because of the way the chart progresses I have to connect two objects with a 'double elbow' version of the 'elbow arrow connector.' I accept that perhaps this complexity means I should redesign the chart, but I've tried and failed to simplify things already. If you'll pardon my ASCII art, this is what I have: +----------------+ | 1 | | | +-------+--------+ | | +-------+--------+ /\ |2 +--------|-----/ 3\ +----------------+ \ / \/ Shape 1 should connect to shape 3, currently the line doing so passes behind shape 2. The diagram below shows what I'd prefer, and, frankly, what I need to happen. +----------------+ | 1 | | | +-------+--------+ | +-----------+ +----------------+ | /\ |2 | +--/ 3\ +----------------+ \ / \/ Having explored the various right-click options I'm either being blind and not seeing it, or...well, I'm hoping it's just me being blind and/or stupid, frankly. If anyone has any suggestions they'd be gratefully received. I'm working with WinXP and Office 2007 (at the university, I run on Ubuntu at home, which possibly explains why I'm missing something potentially simple)...

• Serial port access errors in WINE

  - by goldenmean

  Hello, I have a setup in which I use a USB serial adapter + some application which sends and receives data using that serial usb. But this setup which works on a Windows, or even in a VMWare Virtual windows, does not work under WINE. IT transmits data but i cannot receive data. The cable and the applications are same as in the working and non-working scenarios. I guess The fact that the application works over the USB serial cable just as fine under Virtual Windows(VMware running on linux) by mapping /dev/ttyUSB to the com port, no external software/DLL needed, means it does not need any specific driver. (Am I correct in this assumption that application doesnt need any driver?) (I also tried with a different setup(different USB serial adapter + different application under WINE, but even that does not work under WINE, but it works fine under WIndows/Virtual Windows) How can I get it working under WINE? Any pointers appreciated.

• How can I get the path to a Windows service executable WITHOUT using sc qc?

  - by Jared

  I need to query a windows service for the path to it's executable via the command prompt. I think the way I would do this is:sc qc myServiceName, but when I do that, I get the following error: [SC] QueryServiceConfig FAILED 122: The data area passed to a system call is too small. [SC] GetServiceConfig needs 1094 bytes I think this means that the sc command is sending a data structure to some other library that is too small for the data that needs to be returned. Instead of SC nicely retrying with a larger data structure (1094 bytes) it bombs out and gives me this ugly error message. Thanks Micro$oft. So is there a way to work around this error? I just need the path to the executable, but will parse it out of some other text if needed.

• Xen DomU on DRBD device: barrier errors

  I'm testing setting up a Xen DomU with a DRBD storage for easy failover.

• Http 400 'Bad Request' and win32status 1450 when larger messages are sended to a WCF service

  - by Tim Mahy

  we sometimes receive Http 400 bad request resultcodes when posting a large file (10mb) to a WCF service hosted in IIS 6. We can reproduce this using SOAP UI and it seems that it is unpredictable when this happens. In our WCF log the call is not received, so we believe that the request does not reach the ASP.NET nor WCF runtime. This happens on multiple websites on the same machine each having their own application pool. All IIS settings are default, only in ASP.NET and WCF we allow bigger readerQuota's etc.... The win32status that is logged in the IIS log is 1450 which we think means "error no system resources". So now the question: a) how can we solve this b) (when a is not applicable :) ) which performance counters or logs are usefull to learn more about this problem? greetings, Tim

• What's constitute an entry on the IPTables and how to find out which client it is originated from

  - by cbd

  I have a Billion BiPac 7700N Modem/Router/Access Point and I connect another router (TP-Link TL-WR1043ND) in wan-bypass mode to extend the wireless coverage. Lately, I noticed that the connection through TP-Link has been dropping out quite regularly. Having read some posts on the Internet, I checked system log on 7700N and found that there are many "nf_conntract: expectation table full" errors, which I suppose the iptables are full. My questions: What does constitute an entry on the iptable? Is it a client or a connection (which means one client can have multiple connections) How could I find out where are those connections originated from? Note: Many reported that the issue is usually related to having torrents running but I don't have any torrents running. Thank you.

• What are the consequences of giving an AD domain differing NetBIOS and DNS names?

  - by Newt

  In the past, when creating AD domains, I've used the common convention of using a sub-domain of the company's publicly registered domain name, e.g "corp.mycompany.com" or "int.mycompany.com". I've always accepted the default NetBIOS name when running DCPromo, for fear that creating a NetBIOS name that differs from the sub-domain may cause complications. I've recently been doing a bit of research on the consequences of providing an alternate NetBIOS name. The main reasons behind this are: The NetBIOS name isn't particularly descriptive or unique to the company Apparently generic NetBIOS names such as "CORP" or "INT" can cause issues when merging IT systems (although I've not had experience with this myself) Providing something "before the slash" that means more to users (less important) In looking at the possible downsides, the only one I can come up with is the disjointed namespace issue when configuring Exchange. Can anybody with more experience than I elaborate on my findings at all? Many thanks
