• Is it possible to change "working directory" of XeTeX?

  - by Herbert Sitz

  Using XeTeX there are many working files that get created in process of producing the pdf, and they litter the directory where my main .tex file is. Is it possible to change the working directory of XeTeX so that it stores all these scratch files in some other directory, out of the way? There is a previous question on Superuser.com that discusses a utility that cleans up the working files by deleting them after they're produced: http://superuser.com/questions/95712/how-to-avoid-littering-ones-tex-directories-with-intermediate-files That solution doesn't work for me since I'm using XeTeX, but also it seems like it would be preferable to simply be able to designate a "scratch" directory where all working files are saved. I haven't been able to find any info on how to do it though. Is there a way? (My question is prompted partly because of the fact that I often work with files in a directory that is shared using DropBox, so it creates a lot of unnecessary traffic if files are getting created and destroyed willy nilly. I don't know if it affects speed in any way, but the idea of having a separate working directory that is not shared/replicated by DropBox would be a cleaner solution, even if I could use the method suggested in the earlier thread.)

• Manipulating IIS7 Configuration with Powershell

  - by John Price

  I'm trying to script some IIS7 setup tasks in PowerShell using the WebAdministration module. I'm good with setting simple properties, but am having some trouble when it comes to dealing with collections of elements in the config files. As an immediate, example, I want to have application pools recycle on a given schedule, and the schedule is a collection of times. When I set this up via the IIS management console, the relevant config section looks like this: <add name="CVSupportAppPool"> <recycling> <periodicRestart memory="1024" time="00:00:00"> <schedule> <clear /> <add value="03:31:00" /> </schedule> </periodicRestart> </recycling> </add> In my script I would like to be able to accomplish the same thing, and I have the following two lines: #clear any pre-existing schedule Clear-WebConfiguration "/system.applicationHost/applicationPools/add[@name='$($appPool.Name)']/recycling/periodicRestart/schedule" #add the new schedule Add-WebConfiguration "/system.applicationHost/applicationPools/add[@name='$($appPool.Name)']/recycling/periodicRestart/schedule" -value (New-TimeSpan -h 3 -m 31) That does almost the same thing, but the resulting XML lacks the <clear/> element that is created with via the GUI, which I believe is necessary to avoid inheriting any default values. This sort of collection (with "add", "remove", and "clear" elements) seems to be fairly standard in the config files, but I can't seem to find any good documentation on how to interact with them consistently.

• My .htaccess file re-directed problems?

  - by Glenn Curtis

  I am hoping you can help me! Below is my .htaccess files for my Apache server running on top of Ubuntu server. This is my local server which I installed so I can develop my site on this instead of using my live site! However i have all my files and the database on my localhost now but each time I access my server, vaio-server (its a sony laptop), it just takes me to my live site! Now eveything is in the root of Apache, /var/www - its the only site I will develop on this system so I don't need to config this to look at any many than this one site! I think thats all, all the Apache files, site-available/default ect are as standard. - Please Help!! Many Thanks Glenn Curtis.

• Solaris 10: How to image a machine?

  - by nonot1

  I've got a Solaris 10 workstation that I'd like to create a full image backup from. The machine has 2 drives, one UFS for system root, and 1 ZFS for data storage. I intend to add a third HD to keep the backup images of both primary drives (including any zfs snapshots). The purpose is not disaster recovery, but rather to allow me to easily blow away a series of application installation/configuration changes I intend to try. What's the best way to do this? I'm not too familiar with Solaris, but have some basic Linux knowledge. I looked at CloneZilla, but it does not support Solaris. I'm OK with just a dd | gzip > image style solution, but I'd need some way to first zero-out the non-used blocks on the primary drives to aid gzip. They are are much larger than my 3rd drive, but hardly have any real data. Update to clarify: I specifically want to avoid using any file-system snapshot functionality, because part of the app configuration changes involve/depend slightly on existing and new snapshots. Ideally the full collection of snapshots should be part of the backup. Virtualization not an option, because the goal is to do performance evaluation on a very specific HW configuration. For the same reason, the spurious "back up" snapshots could skew performance data. Thank you

• Copy UNC network path (not drive letter) for paths on mapped drives from Windows Explorer

  - by Ernest Mueller

  I frequently want to share network paths to files with other folks on my team via email or chat. We have a lot of mapped drives here, both ones we set up ourselves and ones set up by our IT overlords. What I'd like to be able to do is to copy the full real path (not the drive letter) from Windows Explorer to send to folks. Example: I have a file in my "Q:" drive, \cartman\users\emueller, I want to send a link to file foo.doc to everyone. When I copy the file path (shift+right click, "copy as path") it gets the file name "Q:\foo.doc". This is unhelpful to others, who would like to see \cartman\users\emueller\foo.doc, obviously. In Explorer it clearly knows it - in the address bar I see "Computer - emueller (\cartman\users) (Q:) -". Is there a way to say "hey man copy that path as text with the \cartman\users\emueller not the Q: in it?" I know I could just set up mapped network locations instead of the mapped drives for the ones that I set up personally and avoid this problem, but most of the mapped drives like the "users" share come from our IT policy. I could just make a separate network location and then ignore my Q: drive but that's inconvenient (and they do it so they can move accounts across servers). Sure my emailed path might eventually break because I'm losing the drive letter indirection but that's OK with me.

• Is the APC BR700G UPS (or similar) compatible with Active PFC power supplies?

  - by David Zaslavsky

  I'm looking at getting a UPS for my home computer. So far the APC BR700G looks very promising, except for one thing: one of the reviews on Newegg says that this UPS does not work with a power supply with Active PFC. Pros: Unit looks great, built well, very heavy, was excited to use it. Cons: Didn't research enough - many newer power supplies like my corsair 750w (and yes dells and other mainstreamers sell them too) that I bought last year have a feature called active pfc (power factor corrected). The signal for this backup battery doesn't fully support that feature and can cause issues. You can find an article on APCs site if you search their user forums for PFC. And the power supply in my computer is, in fact, an Active PFC PSU. I've already found one answer on this site claiming that it's not an issue, that "most quality supplies these days have PFC and work just fine with a UPS." That disagrees with the review on Newegg. Can someone explain this discrepancy? Also, what is it exactly about a UPS that makes it incompatible with an Active PFC PSU? (if anything) Is there some way to tell based on the technical specifications, or do I just have to hunt for reviews online to avoid wasting my money? While any input would be appreciated, I would prefer to get an answer from someone with actual experience with similar UPS's and Active PFC power supplies, who can tell me whether it works or not.

• First web server questions

  - by Graeme

  Hi there, Just looking for some help/suggestions with this. I require my own server for an upcoming project that will be hosting users websites. I want to build a control panel the user can log into and modify their website which will be stored elsewhere on the server. This all seems easy enough, It's just managing domains and emails that confuse me. What should I look for to manage domain names and point them to the correct website and also what would be the best way to manage email accounts/set up new ones etc. I want to avoid cPanel/WHM if possible, I'm looking to control most things through the control panel I will be building. So any suggestions on this would be useful as well, as I will be wanting to add email accounts through php (Can be done using a shell I assume?). I will also be wanting to measure bandwidth used on the websites contained in each users directory, any suggestions on making this possible? I'm really looking for some suggestions on what software to use to set this up, any advice would be really helpful! Thanks, Graeme

• How to Create an XML File from an Excel File

  - by nicorellius

  I have an Excel spreadsheet file that has 5 or so columns and hundreds of lines. I need to convert this (export these data) to an XML file. I'm interested in three of the columns and they correspond to these XML tags, where info1 can be followed by info2, info3, etc... <?xml version="1.0" encoding="UTF-8" ?> <list> <info1> <id>111</id> <value>222</value> <des>333</des> </info1> </list> If possible, I would like to avoid building this XML manually. It wouldn't be too much trouble to rearrange the Excel file such that the three columns I'm interested in were in their own file. But then I would need to export those data into an XML file of the above format. Any ideas?

• Setting Windows 7's Recycle Bin to automatically have a default disk space allocation for deleted files from newly mounted drives

  - by galacticninja

  How do I set Windows 7's Recycle Bin to automatically have a default disk space allocation for deleted files from external hard drives and TrueCrypt-mounted volumes? I remember in Windows XP, I can set a percentage of total disk space that will automatically be used as storage capacity for deleted files by the Recycle Bin, and this will be applied to all external HDs or TC-mounted volumes. Windows 7 defaults to the 'Don't move files to the Recycle Bin. Remove files immediately when deleted' setting for newly mounted external HDs and TC mounted volumes. Since I am expecting deleted files to go to the Recycle Bin, sometimes this causes an 'Oops' when I delete files in external hard drives or TC mounted volumes, as Windows does not move deleted files to the Recycle Bin, but just deletes the files permanently. I have to remember to manually set a custom Recycle Bin storage space for each new drive that is mounted by Windows to avoid this issue. I only use and mount TrueCrypt file containers, not drives. I also don't mount TrueCrypt file containers as removable drives. ('Mount volume as removable medium' is unchecked in Mount Options.) In my $Recycle.Bin > Properties > Security settings, 'System' and 'Administrators' are already set to 'Full Control', while 'Users' only have 'Special Permissions' checked in gray. There are no other groups. I haven't changed or edited anything in these settings. I am using Windows 7 Ultimate.

• nginx: dump HTTP requests for debugging

  - by Alexander Gladysh

  Ubuntu 10.04.2 nginx 0.7.65 I see some weird HTTP requests coming to my nginx server. To better understand what is going on, I want to dump whole HTTP request data for such queries. (I.e. dump all request headers and body somewhere I can read them.) Can I do this with nginx? Alternatively, is there some HTTP server that allows me to do this out of the box, to which I can proxy these requests by the means of nginx? Update: Note that this box has a bunch of normal traffic, and I would like to avoid capturing all of it on low level (say, with tcpdump) and filtering it out later. I think it would be much easier to filter good traffic first in a rewrite rule (fortunately I can write one quite easily in this case), and then deal with bogus traffic only. And I do not want to channel bogus traffic to another box just to be able to capture it there with tcpdump. Update 2: To give a bit more details, bogus request have parameter named (say) foo in their GET query (the value of the parameter can differ). Good requests are guaranteed not to have this parameter ever. If I can filter by this in tcpdump or ngrep somehow — no problem, I'll use these.

• SBD killing both cluster nodes when there are even small SAN network problems

  - by Wieslaw Herr

  I am having problems with stonith SBD in a openais-based cluster. Some background: The active/passive cluster has two nodes, node1 and node2. They are configured to provide an NFS service to users. To avoid problems with split-brain, they are both configured to use SBD. SBD is using two 1MB disks available to the hosts via an multipath fibre-channel network. The problems start if something happens with the SAN network. For example, today one of the brocade switches got rebooted and both nodes lost 2 out of 4 paths to each disks, which resulted in both nodes committing suicide and rebooting. This, of course, was highly undesirable because a) there were paths left b) even if the switch would be out for 10-20 seconds a reboot cycle of both nodes would take 5-10 minutes and all NFS-locks would be lost. I tried increasing the SBD timeout values (to 10sec+ values, dump attached at the end), however a "WARN: Latency: No liveness for 4 s exceeds threshold of 3 s" hints that something isn't working as I would it expect to. Here is what I would like to know: a) Is SBD working as it should killing nodes when 2 paths are available? b) If not, is the multipath.conf file attached correct? The storage controller we use is an IBM SVC (IBM 2145), should there be any specific configuration for it? (as in multipath.conf.defaults) c) How should I go about increasing the timeouts in SBD attachements: Multipath.conf and sbd dump (http://hpaste.org/69537)

• How to convert Markdown files to Dokuwiki, on a PC

  - by Clare Macrae

  I'm looking for a tool or script to convert Markdown files to Dokuwiki format, that will run on a PC. This is so that I can use MarkdownPad on a PC to create initial drafts of documents, and then convert them to Dokuwiki format, to upload to a Dokuwiki installation that I have no control over. (This means that the Markdown plugin is no use to me.) I could spend time writing a Python script to do the conversion myself, but I'd like to avoid spending time on this, if such a thing exists already. The Markdown tags I'd like to have supported/converted are: Heading levels 1 - 5 Bold, italic, underline, fixed width font Numbered and unnumbered lists Hyperlinks Horizontal rules Does such a tool exist, or is there a good starting point available? Things I've found and considered I initially thought that txt2tags would be helpful, but although it can write both markdown and Dokuwiki, it is very tied to its own specific input format I've also seen Markdown2Dokuwiki, and although I'd certainly be willing to use a sed script, even on a PC, this only supports a tiny, tiny part of Markdown's syntax. python-markdown2 also sounded promising, but it only writes out HTML. pandoc - but it doesn't support Dokuwiki output MultiMarkdown - does not appear to support Dokuwiki output

• Multiple *NIX Accounts with Identical UID

  - by Tim

  I am curious whether there is a standard expected behavior and whether it is considered bad practice when creating more than one account on Linux/Unix that have the same UID. I've done some testing on RHEL5 with this and it behaved as I expected, but I don't know if I'm tempting fate using this trick. As an example, let's say I have two accounts with the same IDs: a1:$1$4zIl1:5000:5000::/home/a1:/bin/bash a2:$1$bmh92:5000:5000::/home/a2:/bin/bash What this means is: I can log in to each account using its own password. Files I create will have the same UID. Tools such as "ls -l" will list the UID as the first entry in the file (a1 in this case). I avoid any permissions or ownership problems between the two accounts because they are really the same user. I get login auditing for each account, so I have better granularity into tracking what is happening on the system. So my questions are: Is this ability designed or is it just the way it happens to work? Is this going to be consistent across *nix variants? Is this accepted practice? Are there unintended consequences to this practice? Note, the idea here is to use this for system accounts and not normal user accounts.

• Comprehensive solution for managing patches, event viewing, change management, inventory, etc

  - by Holocryptic

  I'm looking for a solution that incorporates most or all of the following: Patch Management, Server event viewing/tracking, AD change management, ticketing and internal/external kb, remote access - ability to shadow user sessions or create new ones, imaging, and inventory. Our environments contains Windows Servers and ESXi Hosts (We're not completely virtual, but we're moving that direction). Various Cisco and Linksys switches and firewalls. This is a tall order, and I don't know if it can be done on a reasonable budget. I've looked and found some questions on SF that deal with some of this: http://serverfault.com/questions/72015/active-directory-management-tools-for-medium-sized-forest-less-than-1000-users http://serverfault.com/questions/4021/are-there-any-tools-to-do-change-management-with-active-directory-group-policy http://serverfault.com/questions/21752/what-is-a-good-patch-update-management-server What I'm ideally looking for is a reasonably cheap solution that integrates the features into a central interface. We're a non-profit, so money is a limiting factor (the cheaper, the better; but we have a max of $15k). What we are trying to avoid is having to deal with multiple vendors, while maintaining scalability (we're creating more sites that we'll have to manage). Is this possible, or will we have to cobble together something to make it work for us?

• How to limit SMTP delivery to hourly batches

  - by Jeremy W

  Moved over from StackOverflow. Sorry if you saw it there first In an effort to keep us from being labeled spammers by major ISPs (in addition to SPF records, privacy policies, CANSPAM compliance and the like) - I wanted to limit the amount of mail we send out an hour. Is this possible in W2K3 SMTP server? I was looking at outbound connection properties in the SMTP virtual server config screens...It's just not that clear if tinkering with those settings are going to do what I want. In a nutshell, I'd love mail being sent by this server to queue up and send for example, 5,000 messages every 10 minutes or so. Mail is being sent via ASP.Net. Also, I wouldn't be sending 1 million a day. Probably 30,000 tops - and doing that only a few times a month. I'm just trying to avoid a tidal wave of 30k going out in 1 minute and setting off every network spam monitoring alarm in North America. I know I could do it with a combination console app / scheduled job. My question was if there was an easier way to accomplish this with the Virtual SMTP Server settings on Win2k3 Is this possible?

• Insufficient channel capacity of 1GBit

  - by Roman S

  There is a Caching Server (Varnish): it receives data from Amazon S3 on request, saves it for some time and gives it to the client. We have encountered the problem of insufficient channel capacity of 1GBit. Peak load within 4 hours completely chokes the channel. Server performance is sufficient for now. Approximately 4.5TB of data are transmitted per day. More than 100TB are accumulated per month. The first thought that comes to mind is simply to add one more 1GBit port and sleep peacefully until 2GBit are not enough (it may happen quite quickly) or one server is not able to handle it. And then we just need to add new Caching Servers. But now we need a Load Balancer, which will send requests on one and the same URL, always on one and the same server (to avoid multiple copies of the same cached objects). Here are the questions: Does a Balancer need a band equal to sum of all bands of Caching Servers? What shall we do in case there are no ports in a Balancer? Should we add more Balancers or solve the problem by means of Round robin DNS? What are the standard approaches to such problems? Can anyone advise hosting-companies, which can solve this problem? We are interested in American and European markets.

• Tomato/DD-WRT router to act as switch & only NAT some port

  - by fseto

  BACKGROUND: I have a device that must use a real IP address. Currently, my ISP uses DHCP and I can have up to 4 real IP address assigned. However, the cable modem only have 1 ethernet port and it's connected to my router (running Tomato, but can run DD-wrt or other Openwrt if required). Question stems from how I can connect the additional device, requiring a real IP? EASY SOLUTION: would be to get a switch and connect to the CM, Router, and Device. But alas, I want to avoid this route, since: my wiring cabinet in my home is drawing lots of power and heat already Device will be unprotected by any firewall unable to monitor the traffic to/from device. Besides, what would be the FUN in that? =) IDEA: So what I want to do is to configure the router, so that one of the switchport is removed from the normal br0 bridge. Instead, I want to make it behave like a switch on the WAN port. What's the best way of doing this? Should I create another bridge on the WAN & the device port? Can a single port belongs to two bridges? or would I need to create a subinterface first? Would I need a DHCP-relay? Am I expecting too much from my poor cheapie router? +------+ | CM | +--++--+ || +----WAN---------------+ | / \ Router | | BR1?

• Time-Machine backup over SSH tunnel to NFS mount

  - by BTZ

  I've recently started using a new NAS which runs CentOS 6.2. One of the purposes of the NAS would be to serve as a backup target. Whilst I have been using Apple's Time-Machine for a while and I am very satisfied with it, I'd like to continue using it. Backing up directly to an address in my network is no hassle; all works fine. For security reasons I'd like all my traffic to go through an ssh tunnel to the NAS. This way I can avoid needing to get a VPNserver (for personal reasons). As of NFSv4 the NFS deamon is bound to port 2049, which makes it easy for me to direct all traffic through a ssh tunnel. Tunnel: ssh -f admin@ms -L 2000:localhost:2049 -N Mount: mount -t nfs -o nfsvers=4,rw,proto=tcp,sync,intr,hard,timeo=600,retrans=10,wsize=32768,rsize=32768,port=2000 localhost:/mac_backup /Volumes/backup This works fine for Finder/terminal and throughput is almost equal to direct traffic. (CPU of the NAS does ride high when I reach max bandwidth though) Now the problem: With Time-Machine I can't use the NFS mount point mounted on localhost. TM seems to try to connect to it and then give me a "OSStatus error 65". I also tried using NFSv3 (I correctly forwarded all ports) with no luck. Can anyone shed a light on this and/or give a solution?

• IP queue buffer

  - by summerbulb

  I seem to have an issue with IP queue. I have a linux machine that I am using to run some experiments. The linux machine is configured to be a router, having two NICs, connecting two other computers, and managing their network traffic. All incoming packages are captured, using iptables, and analyzed by a C application. The application analyzing the packets has a built-in delay, as part of the experiment. So I have one very fast computer sending packets through my linux-router and a (relatively) slow linux-router that analyses and deals with the packets, one by one. This situation leads to the fact that when I fire up a sender application on one of the computers connected to the linux-router, my IP queue on the linux-router gets filled up (almost) instantaneously. The IP queue's max length is currently set to 1024, and if it overflows, the packets are dropped. This is expected and i'm OK with it. But, (and this is where it gets interesting), every now and then I get the following error: "Failed to receive netlink message: No buffer space available" At start, I thought this was due to the IP queue overflow, but after some analysis i found that sometimes I get the error even if the IP queue buffer did not overflow, and sometime I DON'T get the message even though the buffer DID overflow. When I run > cat /proc/net/ip_queue, I get the following table (also used to monitor the IP queue overflow): Peer PID : 27389 Copy mode : 2 Copy range : 65535 Queue length : 0 Queue max. length : 1024 Queue dropped : 1166875 Netlink dropped : 2916 Looking at the last two values, Queue dropped seems to refer to packets that did not manage to get into the IP queue because the buffer was full. I can see this value rise as I bombard the linux-router. Netlink dropped ( as it's name implies :) ) seems to have to do with the error i'm getting. I did my best to search for material on this error, but wasn't able to find anything that seemed to point me in the required direction. Bottom line: Why am I getting this error and what can I do to avoid it?

• How to take screenshots of WPF applications in correct size and content

  - by Thomas W.

  I usually take screenshots of single windows via the built-in key combination Alt+Print. Unfortunately this does not work well for more and more applications - all of them are WPF applications. Usually the screen shots have at least one of the following properties: the screenshot is larger than expected and contains parts of the screen around the actual window the screenshot has the correct size but includes parts of other windows, e.g. the Windows task bar. Of course the task bar might be in front of the window, but taking screen shots of "normal" programs works fine. How do I take screenshots of WPF application which are correct in size and content? I'd like to avoid the extra effort of checking all the screenshots for correctness, reproducing the situation, taking them again in case of issues or repairing/faking them manually in any pixel manipulation program (e.g. Paint.NET). I observe this on Windows 7 x64 SP 1, all official updates installed, but it might apply to other Windows versions as well (not tested yet). .NET 4.5 is installed. The application itself might only need the built-in .NET 3.5.1. It's reproducible on a virtual machine with the same settings. Examples: Screenshot of an application running in maximized mode. The screen shot includes parts of the task bar. Screenshot of a progress dialog which is behind the task bar. The screenshot also includes the task bar, while it doesn't for non WPF applications.

• How to encourage Windows administrators to pick up scripting?

  - by icelava

  When I worked as an administrator in my first job, I was frustrated that our administration processes with Windows servers were a series of point-and-clicks; we could never match the level of efficiency with the Unix servers which had a group of shell scripts to automate a lot of the work. I soon read about WSH and ADSI and wasted no time learning just how much automation I was able to achieve with scripting. There was a huge problem though - almost none of my Windows colleagues were really interested in learning scripting. They seemed happy with the manually mouse-clicking chores and were never excited at the prospect of using scripts to do the work on their behalf. I struggled to convince them to pick up scripting skills despite the evident increases in efficiency. I left that job in pursuit of a full-time software development career thereafter. Almost a decade on working in various environments and different customers, I still encounter Windows administrators mainly possessing this general "mood" where they would avoid scripting as much as possible. Despite the increasing level of accessibility Windows server technologies are opening up for scripting and automation. I am almost certain the majority of administrators are administrators precisely because they absolutely hate performing any kind of programming duties. What are some means to encourage and motivate administrators that scripting can really help them in the long run?

• Vista won't boot. BSOD: Page fault in nonpaged area

  - by user31576

  Here's the story: I let Windows Update do the updates it wanted to do, then rebooted the computer. The updating process was taking time so I went away. When I came back, my computer was rebooting. It got as far as the Windows logo with the laoding bar. BSOD'd. Rebooted. And I'm stuck in this loop ever since. Looked up on the net, the "Page fault in nonpaged area" seems to be linked to faulty RAM or drivers. So I ran a memory test, it found no error. When I try in safe mode (with promt) I can see a list of drivers being loaded, then I get the same BSOD. I tried to repair using the Vista DVD, it says "nothing to repair". I tried to restore to a previous state, it says "no restore point found". So, my guess is, it's got something to do with the drivers. How can I identify the one causing the BSOD? If you have any other leads, What can I do? By the way, I'm writing from this very computer, running a linux distro I installed after the BSOD loop started. So i guess it's not an hardware issue. I have backed up important data, and will format and reinstall Windows if I must. But I'd like to avoid that. Thanks in advance for any help you can give me.
