  • Developer hardware autonomy in a managed desktop environment [closed]

    - by Troy Hunt
    I’m looking for some feedback on how developer PCs are managed within environments that have a strict managed desktop policy (normally large corporations). For example, many corporate environments control the installation of software and the deployment of patches and virus updates through a centralised channel. This usually means also dictating the OS version and architecture (32 bit versus 64 bit) which will likely also mean standardised hardware configurations. I’m particularly interested in feedback from developers who work in this sort of environment but have a high degree of autonomy over their machines. This might mean choosing your own hardware vendor, OS type and version and perhaps how the machines are built and maintained. I have several specific questions: How do you satisfy the needs of security, governance etc whilst maintaining your autonomy? For example, how do you address concerns about keeping virus definitions and OS patches up to date? Do you have a process for gaining exemption from standard desktop builds and if so, what do you need to demonstrate in order to get this? How have you justified this need to the decision makers? Essentially, what is the benefit to your role as a developer by having this degree of autonomy? Thanks very much everyone. Update: There's a great post from Jean-Paul Boodhoo which addresses the developer tool component of the quesiton here: http://blog.jpboodhoo.com/TheFallacyOfTheStandardizedDeveloperMachineimage.aspx

  • How does one skip “Windows did not shut down successfully” in Win7-64?

    - by XenonofArcticus
    Migrating an app from an expensive and unreliable dedicated embedded x86 box running WinXP-embedded to COTS hardware (Dell E6410 laptop) running normal Win7-64. At this time, it's not feasible to deploy using Windows 7 embedded. The problem is, that the system is still sort of "embedded". The power could shut off at virtually any time without prior warning. We've stripped the OS down and removed the battery capability so that it will power down as desired. The app never writes to the disk, so it's not like we're going to corrupt anything terribly. The system is essentially idle after our app is up and running (with the exception of some computation, graphics, and TCP/IP and serial communications) so the OS enters a pretty stable state rather quickly. After a power-loss however, it rightly complains that Windows did not shut down successfully and presents the user with the Windows Error Recovery text screen. If left alone, it does eventually move on booting just fine, but we'd like to skip that step if possible. WinXP-embedded is designed to do this automatically, so I know it's possible. I've looked at the Kernel Switches but I didn't see anything documented for "Skip Windows Error Recovery". I've also read extensively on the startup process: http://homepage.ntlworld.com./jonathan.deboynepollard/FGA/windows-nt-6-boot-process.html I know I can disable the auto chkdsk in the registry, but that's not the same thing either. So, how do I streamline the boot process to not hassle the user about a situation that will be the regular normal situation?

  • Can't open shared drive after disconnecting vpn

    - by Matt McMinn
    I use a VPN to connect to my office network. On my local network I have another WinXP machine that shares a printer and a few shared folders. While I'm connected to my work VPN, I can access the shared printer and folders on the other machine just fine, and vice versa. Once I disconnect the VPN, I can't access the local machine any more, and the other machine can't access my machine. The network itself seems ok - I can ping the other machine, get to the internet, and get on to a web server shared by the other machine, but I can't get to the shared folders or printer. If I reconnect to the VPN, my access is restored. I'm guessing this is some sort of authentication thing, but I don't know what. Any ideas? Update This problem is bothering me again, so here's an update. Depending on when I first access the WinXP machine, I either have this problem, or the opposite problem. After a reboot, if I (for example) print, then connect to the VPN, I can't access the machine while on the VPN. If after a reboot I connect to the VPN, then print, I can't access the machine off the VPN. In both cases, if I enable/disable the VPN again, I can access the machine again. Thanks

  • Drive letter not appearing after heat-related crash

    - by NickAldwin
    I recently had my old PC (has 3 physical hard drives partitioned into 6 partitions) off while on vacation. When I came back, I turned it on. I hadn't realized the room was warmer than it usually is due to hot weather while I was away. The computer was extremely slow to start up, then it crashed. When i rebooted, it got halfway through chkdsk on one of the non-system partitions, then crashed again. I opened it up and felt the hard drives and immediately shut down the computer and moved it to my basement to cool down because it was so hot. I left it there for a length of time while I reinstalled the A/C. I have now turned it on again. It is working fine, and every drive except for the one with the partition that was being checked has appeared in Windows. I scheduled chkdsk for all of the other partitions anyway, just in case, but I'm worried about that drive. I'm pretty sure the drive itself hasn't broken but that crashing in the middle of a chkdsk repair may have corrupted the data. What would you do in this situation? Most of the data on that drive was backed up, so it's not a huge deal if I lost it, but I'd like to get it back if I could. I also would love to regain usability of the drive, even if I have to wipe it -- but that's a last-resort sort of thing. What do you suggest I do?

  • What may the reason of slowness be (see details in message body)?

    - by Ivan
    I've got a really weird situation I'm beating to solve. A performance problem which looks really like an empty waiting sequence set in code (while it probably isn't so). I've got a pretty powerful dedicated server (10 GB RAM, eight Xeon cores, etc) running Ubuntu 10.04 with all the functionality services (except OpenVPN server used to provide secure access to clients) deployed in separate VirtualBox (vboxheadless) machines (one for the company e-mail server, one for web server and one for accounting/crm server (Firebird + proprietary app server working with Delphi-made clients)). CPU load (as "top" says) is almost always near zero. Host system RAM is close to 100% usage but not overloaded (as very little swapping gets used, and freed (by stopping one of VMs) memory doesn't get reused any quickly). Approximately 50% of guests RAM is used. iostat usually shows near zero %util. Network bandwidth seems to be underused. But the accounting/crm client (a Win32 Delphi application run on WinXP machines) software works hell-slow with this server (and works much better using an inside-LAN Windows server). I just can't imagine what can make it be slow if there are so plenty of CPU, RAM, HDD and bandwidth resources available on clients and on the server even in their hardest moments. Saying bandwidth is underused I not only know that clients and the server are connected to the Internet with a bigger channels than really used (which leaves the a chance they may have a bottleneck of a sort on the route between them), I've tested bandwidth between clients and the server by copying files among them.

  • Tell if IIS is being asked to serve compressed pages?

    - by Graham
    Hi, I'm trying to find out if our IIS server is being asked to serve pages compressed. I'm a noob regarding a lot of this so am working my way through the issues. We're using IIS 6.0 and have correctly turned compression on. If I use Fiddler2 to analyse the HTTP requests via localhost, then Fiddler reports that the pages are compressed. If we then access the server over the network, either via its external URL or via the internal server name, Fiddler reports those pages as uncompressed. Therefore, it's logical to assume that something is getting in the way - presumably our ISA server. Our ISA administrator states that ISA is configured to allow compressed requests but what I want to do is to look at the requests coming through to IIS to see if IIS is being asked to serve pages compressed. I'm fairly convinced that our request is going to ISA, ISA is forwarding these, but not with the "compression" details - therefore IIS is not performing any compression. I've looked at the IIS logs but can't see anything obvious about the HTTP request. Is there any way I can check, on the web server itself, this sort of information? One thing that is confusing, but it may be normal, is that the Client IP making the request is not the orignal PC (i.e. mine) and not the ISA firewall, but the web server itself... Thanks

  • Dns - wildcard vs. cname subdomains

    - by Matthew
    Alright I have to admit I'm confused with how DNS works. I've always just added things until they worked, and now it's time to learn how they work. So one confusing thing to me is that there's sort of two places I can have records. I have an account with rackspace cloud servers. And then there's the place I registered the domain. But both allow me to edit DNS records. Should I do everything at both places or is one better than the other or am I missing the point? Subdomains confuse me too. I'd like to be able to just have a wildcard subdomain (I've done this in the past.) I just don't like the idea of adding a cname record or A record every time I need a new subdomain. Then I read this and it says: The exact rules for when a wild card will match are specified in RFC 1034, but the rules are neither intuitive nor clearly specified. This has resulted in incompatible implementations and unexpected results when they are used.

  • How to do grap data between two file in Linux?

    - by user28167
    I have two .rtf file.... The first one have this content: Apple, Orange, Banana, Noodle, Chip The Second File is something like this: Apple I love eat Apple. Banana I hate Banana. Zoo I want to go Zoo. Noodle Noodle can be a very very very very very very very very very very very long, but still is one line. Chip Don't eat so many chip. Orange Orange is great, not Apple plx. Noodle Water Drinking water is boring. The first file is a "key" of second file. In the second file, the first word is the key of each line. Each key and sentence in second file ONLY have one line. The Second File have many lines with key, but not all the key is shown on file1, but file1's key MUST in the second file. How can I get the result like this: (Need to sort by the key from File1) Apple, Apple I love eat Apple. Orange, Orange is great, not Apple plx. Banana, I hate Banana. Noodle, can be a very very very very very very very very very very very long, but still is one sentence. Chip, Don't eat so many chip.

  • Proper configuration for Windows SMTP Virtual Server to only send email from localhost, and tracking down source of spam emails

    - by ilasno
    We manage a server that is hosted on Amazon EC2, which has web applications that need to be able to send outgoing email. Recently we received a notice from Amazon about possible email abuse on that server, so i've been looking into it. It's Windows Server Datacenter (2003, i guess), and uses SMTP Virtual Server (you know, the one that requires IIS 6 for admin). The settings on the Access tab are as follows: - Authentication: Anonymous - Connection: Only from 3 ip addresses (127.0.0.1 and 2 others that refer to that server) - Relay: Only from 3 ip addresses (127.0.0.1 and 2 others that refer to that server) In the SMTP logs there are many entries like the following: 2012-02-08 23:43:56 64.76.125.151 OutboundConnectionCommand SMTPSVC1 FROM: 0 0 4 0 26364 SMTP - - - - 2012-02-08 23:43:56 64.76.125.151 OutboundConnectionResponse SMTPSVC1 250+ok 0 0 6 0 26536 SMTP - - - - 2012-02-08 23:43:56 64.76.125.151 OutboundConnectionCommand SMTPSVC1 TO: 0 0 4 0 26536 SMTP - - - - 2012-02-08 23:43:56 64.76.125.151 OutboundConnectionResponse SMTPSVC1 250+ok 0 0 6 0 26707 SMTP - - - - ([email protected] is sending quite a lot of emails :-/) Can anyone confirm if the SMTP server settings seem correct? I'm also wondering if a web application on the machine could be exposing a contact form or something that would allow this sort of abuse, looking into that (and how to look into that) further.

  • Win7 'locking' process/files/folders?

    - by Dynde
    I've had a fair bit problems with sometimes files/folders/processes being 'locked' by Windows. The weird thing is, it's not like the traditional sense, I think, where tools like UnlockIT and wholockme would work. It seems that just giving it a little often helps - making me think it could either be the HDD, the memory, or something in Windows. A scenario: I go into a folder - don't open anything at all, go back up, cut or drag-move the folder to someplace else, it says "Action can't be completed because the folder or a file in it is open in another program". Waiting sometimes 20 seconds sometimes a little longer, and I can move it. Another scenario is deleting a bunch of files in a folder, and it appears that everything is gone, but then suddenly after a few seconds an .exe file pops back up, and I can't delete it. Waiting a few minutes, then pressing refresh and it's gone. I have the strangest feeling that there's a problem with either HDD or memory. I already tried disabling Windows indexing service with no luck. Does anyone have any ideas? EDIT: I should say, that I have a very fast system, 16 GB DDR3 RAM, i7-2600k CPU, SSD main HDD, so I really should not be experiencing any sort of problems, where one might say that it's "reasonable" for the system not to respond right away. Edit2: And I updated SSD firmware a couple months ago, so it shouldn't be bad release FW either

  • Recover data from hard drive with partitions (but not most data) overwritten

    - by Macha
    I have a 500GB hard drive I've been keeping around to recover data from that I removed from a failing NAS drive that got sort of... erratic at the end. I finally got rid of the NAS when during a firmware update it removed the partition table. Fast forward to a week ago, when I was building a new PC, and a mixup resulted in me placing the hard drive in question in the new PC and installing Windows XP on the first 100GB. I'm presuming any data on that first 100GB is now gone, but for the rest of it, is there any way I can recover it at home, as professional data recovery is currently too expensive? I have a blank 1TB HDD if I can store any images of that hard drive on. The problem was definitely with the NAS and not the hard drive, as the hard drive had a successful install of Windows when mistakenly place in the new PC, and there were capacitors in the NAS's circuitry clearly broken. The data I want to recover (in order of priority) is: High: Some jpgs of family photos. Medium: Some RAW files. (There are also jpg versions of all of these) Low: Some mp3s, avis and ISOs, I can re-rip most of these if need be, but it'd be handy not to have to. (I don't need a backup lecture, and if you can hold it in from nagging Jeff Atwood for it, you can hold it in from nagging me for it) In short: The partition tables are gone and overwritten. The data is not overwritten, except for an amount equal to the size of a Windows XP SP3 installation.

  • Recommendation for a simple no-frills Windows PDF printer driver?

    - by Scott Bussinger
    I'm looking for an extremely simple Windows PDF printer driver that I can recommend to clients. Ideally it would have these characteristics: When you print something, it should just create it as a temporary file and then display it in their default PDF viewer with no prompting. If they want to save it, they can save it manually from inside the viewer. This workflow should be with no special post-install configuration. Installation should be very simple. A double click the installation program and click "Finish" sort of thing. No complicated multi-step installation, no asking questions your grandmother wouldn't know the answer to (preferably no questions at all), no extra crap being installed. An option for a completely silent installation would be nice, but not necessary. Ideally it would be free to simplify their installing on a small network, but low cost is an option. I've tried a quite a few but none really fit the bill. Some can achieve the first goal but only after careful configuration, some try to install extra toolbars, some have other installation complexities that would make it hard for extremely novice users to succeed. Any suggestions? Thanks!

  • How do I encapsulate the application server from the web and database servers?

    - by SNyamathi
    So I've been doing some reading and it seems like the best practice would be to have separate database, application, and web servers. There are a few things that I've failed to understand - please feel free to recommend any reading materials that would address these topics. Database (assume MySQL) Application server communication: Does the database server do any sort of checks on the SQL commands sent / returned, or is it just a "dumb pipe" that responds to SQL commands by spitting back data? Application server (assume Tomcat) Web Server Almost the reverse here, is it the web server that is more of a pipe to the internet that forwards requests to the application server and spits back responses? I'm not wording this well, but I'm trying to ask - is it the application server that is responsible for validating data received by from requests? ex: Parsing POSTs Validating user logins Encrypting decrypting data Furthermore, how do these two servers communicate? I'm trying to keep things as flexible as possible here, so while I could write a web server in Java and use Java to communicate between the web and app server, that doesn't sound very modular. What if I want to use Python or some other language to replace the web server later on? What if I want to make a non-web facing application used in house written in C++ or something.

  • Playback random section from multiple videos changing every 5 minutes

    - by brian
    I'm setting up the A/V for a holiday party this weekend and have an idea that I'm not sure how to implement. I have a bunch of Christmas movies (Christmas Vacation, A Christmas Story, It's a Wonderful Life, etc.) that I'd like to have running continuously at the party. The setup is a MacBook connected to a projector. I want this to be a background ambiance thing so it's going to be running silently. Since all of the movies are in the +1 hour range, instead of just playing them all through from beginning to end, I'd like to show small samples randomly and continuously. Ideally the way it would work is that every five minutes it would choose a random 5-minute sample from a random movie in the playlist/directory and display it. Once that clip is over, it should choose another clip and do some sort of fade/wipe to the chosen clip. I'm not sure where to start on this, beginning with what player I should use. Can VLC do something like this? MPlayer? If there's a player with an extensive scripting language (support for rand(), video length discovery, random video access). If so, I will probably be able to RTFM and get it working; it's just that I don't have time to backtrack from dead-ends so I'd like to start off on the right track. Any suggestions?

  • Managed LAMP platform for maximizing availability and global reach, not scalability

    - by user66819
    Assume a Linux/Apache/MySQL/PHP application for a small base of registered users. With small userbase, there are no traffic peaks so the scalability that cloud platforms offer is not imperative. But the system is mission-critical, so availability is the primary goal. Users are also distributed across Asia, Europe, and US, so multiple server locations that minimize users' network hops would be highly desirable. The dream: a managed VPS platform where we would configure a single server (uploading PHP and other files, manipulating database, etc.), and the platform would automatically mirror the server in a handful of key places around the world (say one on each US coast, one in Europe, one in east Asia). File system synchronization and MySQL replication would happen automatically. Core operating system is managed, so we don't need to do full system administration and security, and low-level backups are also done by service provider, though we also do our own backups as well. Couple this with some sort of DNS geo-detection, so users are routed to the nearest operational server... with support for https, of course. Does such a dream exist? If not, what are some approaches to accomplish the same end with minimal time investment and minimal monthly hosting costs?

  • Creating a test database with copied data *and* its own data

    - by Jordan Reiter
    I'd like to create a test database that each day is refreshed with data from the production database. BUT, I'd like to be able to create records in the test database and retain them rather than having them be overwritten. I'm wondering if there is a simple straightforward way to do this. Both databases run on the same server, so apparently that rules out replication? For clarification, here is what I would like to happen: Test database is created with production data I create some test records that I want to keep running on the test server (basically so I can have example records that I can play with) Next day, the database is completely refreshed, but the records I created that day are retained. Records that were untouched that day are replaced with records from the production database. The complication is if a record in the production database is deleted, I want it to be deleted on the test database too, so I do want to get rid of records in the test database that no longer exist in the production database, unless those records were created within the test database. Seems like the only way to do this would be to have some sort of table storing metadata about the records being created? So for example, something like this: CREATE TABLE MetaDataRecords ( id integer not null primary key auto_increment, tablename varchar(100), action char(1), pk varchar(100) ); DELETE FROM testdb.users WHERE NOT EXISTS (SELECT * from proddb.users WHERE proddb.users.id=testdb.users.id) AND NOT EXISTS (SELECT * from testdb.MetaDataRecords WHERE testdb.MetaDataRecords.pk=testdb.users.pk AND testdb.MetaDataRecords.action='C' AND testdb.MetaDataRecords.tablename='users' );

  • Gnome, open with, custom command, filename reference

    - by Tergiver
    I want to execute this custom command on a file from the Gnome File Browser: hexdump -C $f > $f.dump That would create a hexdump of the file with the file's name + .dump in the directory that the file exists in. When I say $f above I mean something that would substitute the name of the file that was opened. So I've tried "Open with", "Use a custom command". I can't get it to work. I've tried a number of symbols in place of $f. Is it even possible? Before you suggest getting a GUI hexdump program, this is just one example. I have the need to do this sort of thing for many terminal-type programs. Am I the only person on Earth who wishes for a hybrid File-Browser-slash-Command-Terminal? That would be a file browser which contained a terminal pane who's current directory always matched that of the file browser. One could execute shell commands in the context of what they were viewing in the browser.

  • Data loss by randomly unplugging the computer during runtime

    - by Kan
    I'm from Austria and we and the Germans have some sort of bad science-show which runs every day. What I call it would rougly translate to "half-knowledge" if you want so. By the way: It is called "Galileo". So they thought they'd make a computer myth busters video right now, and I couldn't believe what I saw and heard... The strangest thing to me was that they asked: "Does unplugging the computer damage your data?" Then they started up some machine with Vista on it, started copying some files and randomly unplugged the PC cable, the whole thing around 50 times. After their computer continued to start up normally, they just said "nothing can happen, your data or computer can't be damaged". They of course excluded unsaved data in running programs like text editors from this. I asked myself: What the hell are their "computer experts" saying? You can't tell by unplugging the cable 50 times if that can damage your computer. Can unplugging the cable during runtime cause data loss (as said by the moderator of the show)? (I destroyed my windows registry once during a reset)

  • Standing and sitting while using a computer at work

    - by Adam Batkin
    I would like to be able to comfortably switch between sitting and standing while at work (I'm a software developer, so I spend most of my day in front of a computer). For the past couple of months I have been using a large elevated stand that sits on my desk (designed expressly for this purpose) containing my keyboard and mouse, and my monitors have been raised as high as possible and aimed upwards. So I can stand all day and I'm pretty comfortable (my right wrist may be at too much of an angle when it's on my mouse, but that's a separate issue). The only problem is that sometimes I want to be able to sit. I can easily place my keyboard and mouse back down under the elevated stand, but I have to look up pretty steeply and that is uncomfortable and makes it difficult to see the screens since they are tilted upwards. My monitor mounts are difficult to adjust quickly/easily, so I can't just re-aim them. I would of course love one of those hydraulic standing/sitting desks (cost isn't the problem). But I'm in a row of "trader-style" desks where it's basically a very long surface with people sitting at 6-foot intervals. What type of equipment do you recommend? I suppose the best thing would be some sort of monitor stand (it must be able to hold 2-3 LCDs) that can easily be lowered and raised. But any other suggestions are also welcome.

  • Mapped network drive connection timeout

    - by Terix
    I have server "Alpha" and server "Beta". Server Beta has a shared folder, that is mapped on server Alpha as "X:" On server Alpha there is a .vbs script that runs and take some files on local drive and copy them on X: drive. My issue is if no user log on server Alpha for a long time, it seems like the tcp connection underneath the mapped drive has a timeout, and the vbs script fails on the copy of file. As soon I log with remote desktop on Alpha server, the .vbs is successfull on the copy of the files. I have made many tests, using file logs to check what was happening and I found no way to refresh the connection and let the .vbs be able to copy files unattended.. I have always to log with remote desktop on Alpha server to refresh the connection and let the .vbs copy the files without issues. What can I do to avoid to log every time? The .vbs script runs 3 times a day and is very annoying. I do not have control over server Beta so I cannot change anything there, and I am very limited on changes I can do on server Alpha ( I cannot change registry and that sort of things)

  • Audio server with best API?

    - by Wintermute
    I'm a web dev, working in a small studio with a couple of other devs and some crayon-munchers (or, "designers"). Like all the best and trendiest creative studios, we have tunes. Our tunes consists of a set of speakers that whoever wants to can plug into their machine, and DJ their little socks off via iTunes, Spotify, VLC or whatever their music player of choice happens to be. Obviously, this lacks finesse. What we WANT is this: a single, dedicated machine running some sort of audio player (ideally Win-based, but a Linux flavour isn't impossible), that exposes an API. We (ie: me and the other devs) want to write a web-based client onto it, that'll let us remotely do all sorts of funky stuff like generating on-the-fly genre-based playlists, and voting for tracks, and making tea. My question - and please forgive me if this isn't the place for such a question, I was going to ask on Stackoverflow but that didn't seem right either - is this: what's the best player to start with? What can do all of this? I know VLC can function as a streaming server, but know nothing of any API it may have. I'd rather chop my pinky off than use iTunes, but if it does what we want, then... Anyhow, thanks for reading. All comments and suggestions gratefully received.

  • Hard Disk based storage library

    - by Ryan M.
    We have a Tandberg T24 tape device to handle all of our long term backups right now. We decided that we're not backing up nearly everything that we would like to and that we still have a lot of vulnerabilities. To get to where we want to be, we're going to have to back up a lot more servers than we're currently doing. All of our internal servers have some sort of directly attached drive (I.e. LaCie Raid box or a simple portable hard drive) doing backups, but what we want to do is get those backups off-site. The current tape drive is directly attached via SCSI to a Windows Server 2008 File Server. So to back up anything to tape, it has to be funneled through the File Server. With the current increase that we have planned, I don't think that funneling everything through the File Server is the right course of action and I'm thinking that maybe a second backup device would be more appropriate. I would like your input on a couple of ideas. 1) Doing HDD instead of tape. Tape is hard to deal with. We have a regular rotation cycle, so they don't need years and years of shelf life, so I'm wondering if something HDD-based would be better. 2) Something accessible over the network. Instead of having the device directly attached to one specific machine, have it available to all the servers over the network. Our File Server is a 12-disk raid 6 set up.. I was thinking something like that, but with no raid involved, all disks are stand alone so they can be used/installed/removed on an individual basis. Does any such thing exist? Thanks for your ideas. I'm really interested to hear about some of the solutions you guys are using..

  • Understanding Unix Permissions (w/ ACL)

    - by Dr. DOT
    I am trying to set permissions on my server properly. Currently I have a number of directories and files chmod'd at 0777 -- but I am not comfortable with it being this way. So at the advice of a serverfault specialist, I had my hosting provider install ACL on my shared virtual server. When I FTP to the server as my FTP user account "abc", I can do everything I need to do (and rightfully so) because all my dirs and files are owned by "abc", the group is "abc", and the 1st octet is set to 7 (rwx). That much I get. But here's where it gets dark gray for me. PHP is set to user "nobody". so when someone browses on of my web pages that either ends in .php or has some embedded PHP, I assume the last octet controls the access. Because all my dirs and files are owned by "abc" and assigned to group "abc", if the last octet was a 4 (r--) then the server would let the browser read the file. If it were a 6 (rw-) then the server would let the browser also write to the file or directory, correct? what if the web document does not end in .php or does not have any PHP embedded? What is the user then? how can I use ACL to not set the permission to 6 (rw-) or even 7 (rwx)? [not sure what execute does or means] Just looking for some sort of policy settings to best lock down my dirs and files while allowing my PHP scripts to do uploads and write to files (so my users don't call me to tell me "permission denied". Ok, thanks to anyone out there willing to lend me a hand. It is greatly appreciated.

  • troubleshooting really slow login on a (linux) machine

    - by Peeter Joot
    Within the last couple of weeks, any attempt to login to a specific linux server has gotten really slow. Once I've logged in, things appear to run without significant delay, but some other login like activities (like starting a new screen session) are slow. The machine's been rebooted a couple of times recently and that hasn't helped. , and it doesn't appear to be $PATH search (where $PATH can sometimes include bad NFS mounts), which I've seen historically in our environment. I've also tried completely removing my .profile/.bash*/... type of init files to rule out anything bad there. I also see slow login for at least one other userid on the system. One thing I've noticed is the following message when trying to exit from a screen terminal: Utmp slot not found -> not removed and am wondering if this is related (having a vague recollection that Utmp has something to do with login). Any idea what that message means, or how to fix it, and if it would be related? Failing that, what sort of problem determination tools are available to investigate what is slowing down this login process?

  • I need to take the first three letters of a filename and set it into a text file, in a certain fashion. How can I do this?

    - by JuniorD
    Okay, so I need to take the first three letters of a file from a list of files, and place this into a text file in a certain manner. I will provide examples below. Lets say that I have two file names in the same directory, one called cougar.txt and the other bear.txt. These are in the animals directory. I need to take the first three letters of these words, and transpose them into a text file along with the directory, in the following format: BEA = "animals/bear.txt" COU = "animals/cougar.txt" This should happen with any random thing that might be in the list. I'm fairly new to this sort of coding, so I'm not quite sure which language to use, and I'm learning as I go. This new challenge seems fairly daunting to me, and I would be much appreciated if you guys could help. Also, I'm using Windows 7. Been attempting at this all day, to no avail. Preferably done in batch, but if that is impossible I'm open to recommendations.
