  • Perforce Proxy Server: Caching selective files [closed]

    - by fbrereto
    I just set up a Perforce proxy server for work. I'm noticing the cache directory is filling up very quickly -- with files I know I will never need. For example, there is a 'sandbox' directory in the depot where users keep personal branches and other work; a p4 sync is causing the p4 proxy cache to grab these user's sandboxes when I'll never need them. I would create a symbolic link for the sandbox directory to /dev/null but then I wouldn't be caching my sandbox, which I am interested in. Is there any way to tell the perforce proxy something to the effect of "if I haven't had to sync it, please don't cache it?"

  • Moving a VM from MS Virtual Server R2 to VirtualBox

    - by AngryHacker
    I have a Windows 2000 Professional VM happily running under MS Virtual Server R2 on WindowsXP. I need to move it to a different PC and the only one available is a Mac with VirtualBox on it. Theoretically, VirtualBox accepts .VHD files out of the box, but my attempts to run my VHD on VirtualBox resulted in failure. The Guest OS just keeps rebooting. I've attempted to get help on the VirtualBox forums, and they said that the VM image must first be prepped for the move, but could not give me any specifics. Anyone here know what is specifically involved in moving a Win2k .VHD to VirtualBox on the Mac?

  • OS X Server - setting up a share for network home directories + fast user switching

    - by sohocoke
    I'm nearly finished setting up my Open Directory master to allow users to be managed centrally and logged in on any of the client machines at home. I found discussion suggesting that using an AFP share for the 'Users' automount would result in network users (cf. users defined locally, or Portable Home Directory users) are unable to use fast user switching, as the first user logging in would trigger the automount and mount the 'Users' share with his permissions, preventing further users from using the mount. I've also found some suggestions to configure autofs such that the 'Users' share is mounted prior to any user logging in, but not great amounts of details along these lines. I'd greatly appreciate some instructions to set up autofs - ideally, on the OpenDirectory server rather than each client's etc/fstab or equivalent location, so that it isn't required per every client machine - to get fast user switching working with network users.

  • HTTP 303 redirection and robots.txt

    - by Ian Dickinson
    On a site I'm working on, we're using the HTTP 303 redirect pattern (see this article for background) to distinguish between information and non-information resources. So: some URL's under /id get redirected to dynamically-created pages under /doc. These dynamic pages are built from a database, and contain links to other /doc/ resources, so in general we don't want them to be crawled. Our robots.txt contains: Disallow: /doc However, we do want the non-redirected pages under /id to get indexed by Google et al: Allow: /id So the question I have, which I can't find an answer to so far, is: if an allowed /id page 303-redirects to a /doc page, will it still be blocked by robots.txt? If yes, we're OK, but otherwise I'm going to disallow all /id resources in the robots file, as having the crawler hammer the db would be worse than losing search indexing for the /id pages.

  • Google crawler not found an error inside of the <head> tag

    - by inckka
    I've found a crawler error in my site and it is listed as a page not found(404) link. Heres the broken link http://mydomain.com/blog/comments/feed/ I'm using Google web master tools and found that broken link coming from my web site pages' head tag. here's actual code where that link situated. <head> <link rel="alternate" type="application/rss+xml" title="My Domain Blog &raquo; Feed" href="http://www.my-domain.com/blog/feed/" /> </head> So Google report this link as a not found. Actually this link target is not an exact page or a location. But essential for the blog feeds. Anyway I have to fix this and remove from the Google crawler error's list. But haven't got any idea, because cannot redirect or do a 404 header with this link target. Have anyone got an idea of fixing this?

  • Varnish doesn't seem to be caching

    - by Charlie Somerville
    I've setup a Varnish cache mirror to sit in front of a file server, but it seems to be endlessly re-downloading data from my file server. There's about 100GB of data in total, but so far Varnish has downloaded 800GB from my file server. I'm using the default VCL file that comes with Varnish and the response headers for files served by the file server are similar to the following: HTTP/1.1 200 OK Cache-Control: max-age=290304000, public Content-Type: image/jpeg Expires: Wed, 29 Dec 2010 21:38:33 GMT Server: Microsoft-IIS/7.0 E-Tag: "8b4723296ab697530768f18b1378b269" Content-Disposition: inline; filename=image046.jpg; X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Thu, 23 Dec 2010 05:38:33 GMT Content-Length: 100592 I'm starting varnishd with the following options: varnish/sbin/varnishd -a 0.0.0.0:80 -f varnish/etc/varnish/default.vcl -s file,varnish/var/lib/varnish/varnish_storage.bin,100G

  • Tips for communication between JS browser game and node.js server?

    - by Petteri Hietavirta
    I am tinkering around with some simple Canvas based cave flyer game and I would like to make it multiplayer eventually. The plan is to use Node.js on the server side. The data sent over would consists of position of each player, direction, velocity and such. The player movements are simple force physics, so I should be able to extrapolate movements before next update from server. Any tips or best practices on the communications side? I guess web sockets are the way to go. Should I send information in every pass of the game loop or with specified intervals? Also, I don't mind if it doesn't work with older browsers.

  • Is it possible to get a Proxy Authentication Dialog with Ubuntu Server?

    - by Johnny Bigoode
    I've got a VM Virtual Box with Ubuntu Server. I'set the http_proxy variable using export http_proxy="http://1234:linux@proxy:8080" The problem is that Ubuntu will constantly try to connect to the internet, even when I'm not logged in my company's account, so everyday I need to reset my password since Ubuntu will constantly try to access the internet. Also, it's always a problem when I need to authenticate the proxy with a different user/password. Can't I just set it to make a small prompt when it tries to connect to the proxy and fails? Like Firefox, Chrome and every app I have installed with Windows 7? I get this small dialog box that asks for a username and password when it can't access the internet. The Ubuntu Server doesn't need constant internet connection, specially since it's only online for tests over LAN.

  • RequestContextHolder.currentRequestAttributes() and accessing HTTP Session

    - by Umesh Awasthi
    Need to access HTTP session for fetching as well storing some information.I am using Spring-MVC for my application and i have 2 options here. User Request/ Session in my Controller method and do my work Use RequestContextHolde to access Session information. I am separating some calculation logic from Controller and want to access Session information in this new layer and for that i have 2 options Pass session or Request object to other method in other layer and perform my work. use RequestContextHolder.currentRequestAttributes() to access request/ session and perform my work. I am not sure which is right way to go? with second approach, i can see that method calling will be more clean and i need not to pass request/ session each time.

  • "X-Robots-Tag: noindex" on an HTTP 301 response

    - by Peter O.
    I understand that a resource with X-Robots-Tag: noindex forces some search engines, including Google, not to index the resource further. I also understand that an HTTP 301 response causes search engines to use the redirected URL instead of the original URL to refer to the resource. But what happens if both "X-Robots-Tag: noindex" and status code 301 occur on the same response? It's likely that the original URL will no longer be indexed, but will that cause the redirected URL to no longer be indexed too? This possibility is not mentioned in the X-Robots-Tag specification.

  • URL Rewrite http to https EXCEPT files in a specific subfolder

    - by BrettRobi
    I am trying to force all traffic on my web site to use HTTPS, using the URL Rewrite 2.0 module added to IIS 7.5. I got that working and now have a need to exclude a couple of pages from using SSL. So I need a rule to rewrite all URL except those referencing this folder to HTTPS. I've been banging my head against the wall on this and am hoping someone can help. I tried creating a rule to match all URL except those in a nossl subfolder as in this example: <rule name="HTTP to HTTPS redirect" enabled="true" stopProcessing="true"> <match url="(/nossl/.*)" negate="true" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false"> <add input="{HTTPS}" pattern="off" /> </conditions> <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Found" /> </rule> But this doesn't work. Can anyone help?

    - by user10711
    Using Ubuntu 10.04. Whenever I run Firefox I get a pop up requesting authorisation. It says 'a user name and password are being requested by http://localhost:51675. The site says "server" I have tried all passwords I know and nothing is accepted. If I click 'cancel' it disappears but re-appears after about 5 minutes. This whole 'experience' is accompanied by a great deal of hard disc activity. Can anyone help with this?

    - by raza naqvi
    I have installed Windows Server 2012 and then configured remote applications. At first it was working fine and I could be able to connect remotely and run remote applications from Windows 8 clients. But after few days the following error occurred: Remote Desktop Connection This computer can't connect to the remote computer. Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator. However I still can connect from Windows 7 without any problem. Only Windows 8 has a problem and cannot connect remotely. Neither remote apps nor RDP is working.

  • How do I reinitialise a failed RAID 5 drive using terminal on Ubuntu Server

    - by Stephen
    I've currently put together a new system and part of that has been creating a software RAID 5 using 'mdadm' in Ubuntu Server. I successfully got to the point where I create the array using: sudo mdadm --create --verbose /dev/md0 --level=5 --raid-devices=4 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 I left it to do its thing overnight then used the following command to check on it: watch cat /proc/mdstat To which the following was returned: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid5 sdd1[4](S) sdc1[2] sdb1[1] sda1[0](F) 5860535808 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/2] [_UU_] unused devices: <none> It appears that one has failed (and I'm not too savvy with why another is a spare). So, just to be sure that something else isn't amiss I wanted to try and re-engage the failed drive. Can someone explain how I can do that and what I should do with the spare (if anything). And also how do I know when synchronisation is complete? The tutorial I used to get this far is located here: http://sonniesedge.co.uk/2009/06/13/software-raid-5-on-ubuntu-904/ Many thanks! p.s.

  • Windows Home Server Passwords Do Not Match

    - by Ben Fulton
    I have a Windows Home Server that chunks along just fine most of the time. I've never bothered to put it on a UPS and so it's vulnerable to power outages that happen a few times a year. This most recent time, it came back and seemed to be fine, but whenever I try to access a shared folder I get "Passwords do not match". They matched before the power went out, and I couldn't update the WHS password since I apparently didn't know the old one. How do I fix this? (I asked this on ServerFault and they recommended it be asked here instead)

  • How to properly do weapon cool-down reload timer in multi-player laggy environment?

    - by John Murdoch
    I want to handle weapon cool-down timers in a fair and predictable way on both client on server. Situation: Multiple clients connected to server, which is doing hit detection / physics Clients have different latency for their connections to server ranging from 50ms to 500ms. They want to shoot weapons with fairly long reload/cool-down times (assume exactly 10 seconds) It is important that they get to shoot these weapons close to the cool-down time, as if some clients manage to shoot sooner than others (either because they are "early" or the others are "late") they gain a significant advantage. I need to show time remaining for reload on player's screen Clients can have clocks which are flat-out wrong (bad timezones, etc.) What I'm currently doing to deal with latency: Client collects server side state in a history, tagged with server timestamps Client assesses his time difference with server time: behindServerTimeNs = (behindServerTimeNs + (System.nanoTime() - receivedState.getServerTimeNs())) / 2 Client renders all state received from server 200 ms behind from his current time, adjusted by what he believes his time difference with server time is (whether due to wrong clocks, or lag). If he has server states on both sides of that calculated time, he (mostly LERP) interpolates between them, if not then he (LERP) extrapolates. No other client-side prediction of movement, e.g., to make his vehicle seem more responsive is done so far, but maybe will be added later So how do I properly add weapon reload timers? My first idea would be for the server to send each player the time when his reload will be done with each world state update, the client then adjusts it for the clock difference and thus can estimate when the reload will be finished in client-time (perhaps considering also for latency that the shoot message from client to server will take as well?), and if the user mashes the "shoot" button after (or perhaps even slightly before?) that time, send the shoot event. The server would get the shoot event and consider the time shot was made as the server time when it was received. It would then discard it if it is nowhere near reload time, execute it immediately if it is past reload time, and hold it for a few physics cycles until reload is done in case if it was received a bit early. It does all seem a bit convoluted, and I'm wondering whether it will work (e.g., whether it won't be the case that players with lower ping get better reload rates), and whether there are more elegant solutions to this problem.

  • Home Media Streaming Server

    - by sharjeel
    I'm looking for a Home Media Server which can stream videos to various devices including iPhone, iPad, Windows Machines, Android etc. I wouldn't want to install any client on any device; a web interface will be preferred. Also, it should be able to read videos of as many formats as possible and should stream by transcoding the resolution and format according to device's specifications. I have a fairly powerful machine on which I'm free to install Windows 7 or Linux. The streaming will be done over a g/n WiFi router or Ethernet locally. What is the suggested solution in my case?

  • Server 2008 locks me out when not using the machine for 10 minutes after installing SP2

    - by Daniel Magliola
    I have recently installed Service Pack 2 on my Windows Server 2008 machine (which I use actively for development, and i'm always logged on to). Now, after this installation, when I don't use the machine for some time (let's say, 10 minutes), it locks itself so I have to press Ctrl+Alt+Del and log back in. I have already checked the Screen Saver settings, and it's "None", as it always has been. I also looked into power settings and everything looks right (20 mins to turn off monitor, and i haven't found any settings regarding locking me in there). Do you have any idea what I can do so that it won't lock me out after not using the machine for a while? Thanks! Daniel

Thanks for any advice.

    I have a site www.example.com for which i purchased SSL cert and installed. And it was working fine, I also have a subdomain with app.example.com which was not on SSL. Both www.example.com and app.example.com are on same IP address.

  • Dreamweaver Files uploaded to Win 2008 server cause login prompt

    - by Lil
    I have a customer who uses a 4 year old version of Dreamweaver to edit her webpages. My hosting reseller account is with a company that uses Windows Server 2008. Every time my customer edits a page and uploads it, I have to set the permissions for that file to be readable, manually from the site's control panel. The customer is furious with me because her files cause the login prompt. I am able to upload files myself that remain readable to the site with both Filezilla and with Frontpage. I am assuming that her Dreamweaver settings are the cause of the problem but I don't have that program myself and don't know what to advise her. Any suggestions?

  • HTTP Session Invalidation in Servlet/GlassFish

    - by reza_rahman
    HTTP session invalidation is something most of us take for granted and don't think much about. However for security and performance sensitive applications it is helpful to have at least a basic understanding of how it works in Servlets. In a brief code centric blog post Servlet specification lead Shing Wai Chan introduces the APIs for session invalidation and explains how you can fine tune the underlying reaper thread for session invalidation when it is needed in GlassFish 4. Don't hesitate to post a question here if the blog is not clear, this is a relatively esoteric topic...

  • Home Network Photo Server

    - by CMP
    I am looking for a photo solution for our home network. We have several computers, running windows and OS X. I would like to store all of our photos in a central location, and have them be accessible from any machine. Most of our photos are currently in an iPhoto library, and ideally there would still be a way to import photos from the server to iPhoto easily. This can run really on any operating system, but it must be easily accessible for anybody. A gallery type view would be good, but also must allow direct file access and transfers. Anybody have a solution that works for them, or any ideas of what I could do?
