• FTP FileWatcher

  - by Meiscooldude

  So, I am in this little predicament where I am stuck watching a few ftp folders to see if they have new files added to them. If they do, it needs to throw an event with the file name. Thereby telling something else to download that file. This is a pretty simple object to make, I was just curious if anyone knew how expensive this operation would be? I plan on using the command NLIST because I don't need file size information, and there will be no sub-directories in the folder. Each file in the folder will have exactly 25 characters in its name. There could be anywhere from 10 to 'maybe' a couple thousand (max around 2000) files per folder (usually on the lower end, 100-300, but currently growing). The files are anywhere from 250kb to a very VERY unlikely 10mb (usually within the 250kb to 4mb range). There possibly could be up to a few hundred folders (in which case I could change the watch frequency depending on number of folders), but currently there are only a few (6-10ish). There also would be multiple logins for the ftp server, different logins would have access to different folders. I am not asking for an implementation, just if anyone has some first or second hand knowledge about FTP, how could this affect my network. I am not opposed to putting in file retention times or change the frequency in which I check for new files.

• tail -f and then exit on matching string

  - by Patrick

  I am trying to configure a startup script which will startup tomcat, monitor the catalina.out for the string "Server startup", and then run another process. I have been trying various combinations of tail -f with grep and awk, but haven't got anything working yet. The main issue I am having seems to be with forcing the tail to die after grep or awk have matched the string. I have simplified to the following test case. test.sh is listed below: #!/bin/sh rm -f child.out ./child.sh > child.out & tail -f child.out | grep -q B child.sh is listed below: #!/bin/sh echo A sleep 20 echo B echo C sleep 40 echo D The behavior I am seeing is that grep exits after 20 seconds , however the tail will take a further 40 seconds to die. I understand why this is happening - tail will only notice that the pipe is gone when it writes to it which only happens when data gets appended to the file. This is compounded by the fact that tail is to be buffering the data and outputting the B and C characters as a single write (I confirmed this by strace). I have attempted to fix that with solutions I found elsewhere, such as using unbuffer command, but that didn't help. Anybody got any ideas for how to get this working how I expect it? Or ideas for waiting for successful Tomcat start (thinking about waiting for a TCP port to know it has started, but suspect that will become more complex that what I am trying to do now). I have managed to get it working with awk doing a "killall tail" on match, but I am not happy with that solution. Note I am trying to get this to work on RHEL4.

• How do you do a keyword search the Services.msc (mmc) window in Windows 7?

  - by Warren P

  When you want to run a service, you have very limited capabilities, in all current Windows versions, as far as I can tell. I usually start Services by typing "services.msc" into the Start-Run box, on most versions of Windows, this works. I know how to click the "Name" column in the MMC view of Windows Services. If you know what the first few characters of a service name is, you can usually sort by the name, and type the prefix to scroll the list down (find Windows Search for example). This seems pretty weak to me, so I spent some time searching the interwebs for tools that do a better job of managing services. Usually I have a keyword that I know "fooWare" might be the keyword, and I need to find the (usually badly named) service and start it and stop it. This is often WAY too hard. The best I could do is "NET SERVICES" from the command line, and maybe add a grep in there, but that doesn't list every service, only a few of them. And the MMC snap-in in Win7 now has an Export List button, exporting to csv text file feature which I have used from time to time, to export and then search. I have thought of writing my own tool. I'm hoping a better "service manager" utility exists out there that sysadmins use. I'd like a search box at the top right corner, kind of the same way that the Add-Remove-Programs dialog in Win7 and Vista has a search facility. Does such a services utility exist out there?

• Windows Server NTFS volume list file name encodings and any illegal file names

  - by benbradley

  I'm having to deal with a Windows Server (NTFS) file server and our backup application appears to be failing with certain files. According to this https://en.wikipedia.org/wiki/NTFS#Internals NTFS apparently supports file names encoded in UTF-16 but according to their support team, our backup application only supports UTF-8. I'd like to confirm whether this is actually the problem by seeing the file name encoding for myself. The files that are failing appear to be using plain English A-Z letters and other ASCII characters. No accents or non-English letters etc. I suppose even though the letters appear to be plain A-Z the file name could still be encoded in UTF-16. Does anyone know of a utility or script that can recursively go through all files in a directory and show the encoding of the file name? Then I could try renaming to UTF-8 to see if the backup can proceed. I'm not a Windows developer so can't write this up myself. Presumably the encoding of the file name should be stored in the FS somewhere and therefore it should be possible to expose this.

• Remote Socket Read In Multi-Threaded Application Returns Zero Bytes or EINTR (104)

  - by user39891

  Hi. Am a c-coder for a while now - neither a newbie nor an expert. Now, I have a certain daemoned application in C on a PPC Linux. I use PHP's socket_connect as a client to connect to this service locally. The server uses epoll for multiplexing connections via a Unix socket. A user submitted string is parsed for certain characters/words using strstr() and if found, spawns 4 joinable threads to different websites simultaneously. I use socket, connect, write and read, to interact with the said webservers via TCP on their port 80 in each thread. All connections and writes seems successful. Reads to the webserver sockets fail however, with either (A) all 3 threads seem to hang, and only one thread returns -1 and errno is set to 104. The responding thread takes like 10 minutes - an eternity long:-(. *I read somewhere that the 104 (is EINTR?), which in the network context suggests that ...'the connection was reset by peer'; or (B) 0 bytes from 3 threads, and only 1 of the 4 threads actually returns some data. Isn't the socket read/write thread-safe? I use thread-safe (and reentrant) libc functions such as strtok_r, gethostbyname_r, etc. *I doubt that the said webhosts are actually resetting the connection, because when I run a single-threaded standalone (everything else equal) all things works perfectly right, but of course in series not parallel. There's a second problem too (oops), I can't write back to the client who connect to my epoll-ed Unix socket. My daemon application will hang and hog CPU 100% for ever. Yet nothing is written to the clients end. Am sure the client (a very typical PHP socket application) hasn't closed the connection whenever this is happening - no error(s) detected either. Any ideas? I cannot figure-out whatever is wrong even with Valgrind, GDB or much logging. Kindly help where you can.

• How to configure IIS for SVG and web testing with Visual Studio?

  - by macias

  Let's say I have a simple web page with svg image in it: <img src="foobar.svg" alt="not working" /> If I make this page as static html page and view it directly svg is displayed. If I type the address of this svg -- it is displayed. But when I make this as .aspx page and launch it dynamically from Visual Studio I get alt text. If I type the address of this svg (from localhost, not as a local file) -- browser tries to download it instead of displaying. I already defined mime type in IIS (for entire server -- "image/svg+xml") and restarted IIS. Same effect as before. Question: what should I do more? Update WireShark won't work (it is in documentation), I tried also RawCap, but it cannot trace my connection (odd), luckily Fiddler worked: From client: GET http://127.0.0.1:1731/svg/document_edit.svg HTTP/1.1 Host: 127.0.0.1:1731 User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:10.0.1) Gecko/20100101 Firefox/10.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Answer from server: HTTP/1.1 200 OK Server: ASP.NET Development Server/10.0.0.0 Date: Thu, 16 Feb 2012 11:14:38 GMT X-AspNet-Version: 4.0.30319 Cache-Control: private Content-Type: application/octet-stream Content-Length: 87924 Connection: Close <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!-- Created with Inkscape (http://www.inkscape.org/) --> <svg xmlns: *** FIDDLER: RawDisplay truncated at 128 characters.

• System recognizes admin password on the Welcome screen but not when elevating

  - by Lee C.

  I set up Windows 7 with a couple of standard accounts, and an administrator account (called Odin). I can log in to Odin just fine from the Welcome screen. While logged into Odin I can do anything that requires administrator privileges without a password: just hit Yes in the User Account Control dialog. If I am logged into one of the other accounts and I do something that requires elevation (e.g. most installers, and some control panel functionality), then Windows presents me with a User Account Control dialog asking "Do you want to allow the following program to make changes to this computer? To continue, type an administrator password, and then click Yes." The account shown in this dialog is Odin, so I enter Odin's password. But Windows redisplays the dialog with the message "Logon failure: unknown user name or bad password." This always happens, and has done so for many months, probably since I first got the computer. Why does Odin's password work from the Welcome screen, but not when elevating? Please note that I am not asking how to recover Odin's password. I remember the password I originally set for Odin, and it works as it should from the Welcome screen, but is not recognized when elevating. The password has no funny characters, just letters and digits. Thanks!

• Non-alphanumeric character folder name auto-completion problems

  - by viking

  I have been working with Windows 7's command line and have some folders that begin with non-alphanumeric characters. When I try to use tab completion to complete the folder name, the initial character is not included inside of the quotation marks. Example: C:\Users\username\!example is the folder I want to get into, but when I type: cd ! and press <Tab> to autocomplete, it will complete to cd !"!example" instead of the expected cd "!example" Any ideas on how to fix this besides changing the folder names? EDIT: I realize I could just tab through the entire list after entering cd, but I'm looking for a way to speed up the process. I have been spending a significant amount of time navigating these folders. UPDATE: This also happens if there is a space in the directory. For example: "c:\Program Files". In order to continue using tab to complete, first the second quote has to be deleted. C:\Program press Tab "C:\Program Files" is what appears. To navigate to a subdirectory, first the quote after Program Files has to be deleted before the next directory can be spelled out.

• Monospace font which supports at least both of Korean hangul and the Georgian alphabet?

  - by hippietrail

  Being both a language enthusiast and a programmer, I find myself often doing programming or text processing involving foreign language alphabets and scripts. One annoyance however is that CJK fonts (those which support Chinese, Japanese, and/or Korean) usually only contain glyphs for Latin, Greek, and Cyrillic at best. Often the Asian glyphs will be beautiful but the other glyphs can be quite ugly. Just as often in text editors you can only choose a single font, not one for CJKV and one for other, which will be each used for rendering the appropriate characters. Korean is one of the languages I'm most interested in currently. I only need hangul / hangeul for monospaced editing, hanja isn't common enough to be a problem. Another of the languages I'm currently involved in is Georgian, which has its own alphabet which is a little exotic but has pretty good support in common fonts on Windows and *nix. But I am as yet unable to find a font with good Korean glyphs and also Georgian glyphs. My editor of choice is gVim, so an answer telling me how to set it to use two fonts together would be just as good. Currently I'm using it mostly under Windows 7 so a vim-specific solution would be needed rather than a *nix-specific solution.

• Can't Configure IBM 8275-416 Switch Via Serial

  - by Sean M

  I am attempting to configure an IBM 8275-416 switch (I found a manual here) via serial connection. However, when I connect with HyperTerminal, the output contains a lot of garbage characters. It's pretty much unusable, because there's enough layout-breaking text-gunk that it's very difficult to determine what's actually being displayed. . I was able to reset the switch to factory defaults via the terminal interface, so I know that it's not entirely broken. It also performs basic functions all right (i.e., you plug in clients and Ethernet cables - they can connect to clients plugged into other ports) - but I'd like it to do more than that (VLANs yay). I don't know if its in-band UI is operational or not, because I can't get the terminal interface to behave well enough to properly turn on the web/SNMP UI. So that's not available. Things I've tried: - Changing the encoding: HyperTerminal lets me choose between Standard JIS and Shift-JIS. Neither setting fixes the issue. - Checking emulation settings: The manual demands VT100, 19200 baud, 8 data bits, and such: I have faithfully applied these settings, both in HyperTerminal's settings and in the properties of the COM1 port in Device Manager (connecting from a Windows machine). - Restoring to factory defaults: See above. Things that it could be, but that seem unlikely: - Cabling: Couldn't find a proper null-modem cable, so used two 232-to-RJ45 adapters. But if it was a problem with the cable, wouldn't it be more likely to not connect or do input at all, rather than just garble the text? Since I was actually able to perform the reset-to-factory defaults operation, I don't think it's this. - Device as a whole broken: It is a decade and change old, so it's possible that it's just dying slowly. Again, though, it seems like there would be more symptoms than just garbled text in the terminal. What else can I try to get a sane interface to this switch?

• saving and searching encrypted mail

  - by student

  I often send and receive gpg-encrypted mail. At the moment I use thunderbird + enigmail (in linux) to do that. As far as I know there is no way in thunderbird to find all encrypted messages which bodies contain particular keywords. There also seems to be no option to save encrypted mails decrypted (so they would be searchable). However for me it is important to be able to search old encrypted mails. So my question is: Is there a way in linux to save incoming mails automatically decrypted in my inbox and save outgoing encrypted mail decrypted in the send folder? Both times adding a line to the body which remarks that the mail was encrypted. It could be another email client for linux that could to that or perhaps a solution using procmail or maildrop. For a procmail solution I guess there could be some problems with encoding (perhaps one have to use emil?) the solution should work well with german special characters in subject and body. Note that the solution should work for multipart encrypted messages (including encrypted attachments) too i.e. with everything which could thunderbird + enigmail generate. Further note that I don't want a discussion about security holes. For me it's ok if messages are stored decrypted on my harddrive (which is encrypted as a whole anyway). In doubt for a first solution it would be ok to store my private key passphrase in cleartext on my harddrive, too. The point is that the mails are encrypted on the mailserver or more generally on their "way through the net".

• KeePass lost password and/or corruption due to Dropbox/KeePassX

  - by GummiV

  I started using Keepass about a month ago to hold my passwords and online accounts info. Everything was stored in a single .kdb file, only protected with a password. I'm using Windows 7. Now Keepass can't open my .kdb file with the error "Invalid/wrong key". I'm fairly confident I have the right password. Altough I might have mixed up a few letters I've tried about two dozen different combinations to minimize that possibility - but can't rule it out though. My guess is however that the .kdb file got corrupted, either due to Dropbox syncing (only using it on one computer though) or because I edited the file using KeePassX on Ubuntu (dual boot on the same computer, accessing a mounted Win7 NTFS partition), or possibly a combination of both. I have tried restoring older versions(even the original one) from Dropbox and trying out all possible passwords without any luck. (which does seem to rule out KeePassX as the culprit, since oldest copies are before I edited the file from Ubuntu) I have tried opening the file with the "Repair KeePass Database file" which always gives the "0xA Invalid/corrupt file structure" (the same error for when a wrong password is typed). I was wondering if there was any way for me to salvage my hard-gathered data. I know generally that brute force cracking is not feasible, but since I can remember probably more than half of the usernames/passwords, any maybe the fact that one of them does come up fairly often (my go-to pass for trivial stuff), that might simplify the brute force process to a doable time frame. Maybe the brute-force thing might incorporate the fact that I know the password length and what characters it's made from. (If we assume corruption, not a password-blackout on my part) I could do some programming if there are any libraries or routines that I could use. Other people seem to have had a similar probem http://forums.dropbox.com/topic.php?id=6199 http://forums.dropbox.com/topic.php?id=9139 http://www.keepassx.org/forum/viewtopic.php?t=1967&f=1 So hopefully this question will become a suitible resource for people when searching the web. Feel free to tell me if you think this should rather be a community wiki.

• Queries passed to SQL Server are getting corrupted

  - by adrianbanks

  We are experiencing a bizarre error with our application at a customer site. We have managed to narrow it down to the point where we can replicate the behaviour using just Management Studio and SQL Server. We have two machines, A and B: +------------+ +--------------------+ | [A] | | [B] | | Management | -------------- | SQL Server 2008 R2 | | Studio | | Enterprise x64 | +------------+ +--------------------+ We are running a SQL script in Management Studio on machine A against the SQL Server instance on machine B. We are not actually executing the script, just parsing it. Most of the time, the parse operation works fine. Occasionally (seemingly randomly), the parse operation fails with a syntax error. The error message shows the part of the script with the error, which appears as some SQL from the original script that has been truncated and has random characters appended to it. An example: The original SQL: SELECT DISTINCT ST.TABLE_NAME as TableName FROM INFORMATION_SCHEMA.TABLES AS ST INNER JOIN INFORMATION_SCHEMA.COLUMNS AS SC ON SC.TABLE_NAME = ST.TABLE_NAME WHERE ST.TABLE_TYPE = 'BASE TABLE' AND SC.COLUMN_NAME = 'Identity' AND ST.TABLE_NAME != 'dtproperties' ORDER BY ST.TABLE_NAME The SQL that is in error (as reported by SQL Server): SELECT DISTINCT ST.TABLE_NAME as TableName FROM INFORMATION_SCHEMA.TABLES AS ST INNER JOIN INFORMATION_SCHEMA.COLUMNS AS SC ON SC.TABLE_NAME = Sa? The above example shows how the query is being corrupted. It doesn't always happen, and is not always the same bit of SQL that causes the error. Parsing this script against another SQL Server instance produces no errors, showing that the script is fine. It appears that something is corrupting the SQL that is being received the the server. This leads me to think that the problem lies either with the client end or in the transmission of the SQL from the client to the server. I have a SQL trace from the period where an error occurs, which shows the SQL has been corrupted when SQL Server receives it. We have been unable to track down any possible cause of this behaviour, and so cannot find a fix. Because the errors occur seemingly randomly, it is also very hard to generate reproduction steps to submit a bug report. Any ideas?

• No password is complex enough

  - by Blue Warrior NFB

  I have one user in my AD domain who seems to not be able to self-select a password. I may have another one, but they're on a different enough password-expiration schedule that I can't remember who it is right now. I can set a password via ADU&C just fine, but when he tries it via C-A-D he gets the "doesn't meet complexity" message. Figuring he was just doing something like 'pAssword32', I did some troubleshooting of my own and sure enough it doesn't want to take a password that way. He's one of our users that habitually uses a local account and then maps drives using his AD credentials so he doesn't get the your password will expire in 4 days, maybe you should change it prompts, so he's a frequent "my password expired, can you fix it" flyer. I don't want to keep having him set it via ADU&C over my shoulder every N days. I'm just fine setting temp passwords of 48 characters of keyboard-slamming and letting him change it something memorable. My environment is at the Windows 2008 R2 functional level, and I am using fine-grained password policies. In fact, I have two such policies: For normal users (minimum length, remembered passwords) For special utility accounts The password complexities I've tried match both policies for length and char-set selection. The permissions on the User object themselves look normal, SELF does indeed have the "Change Password" right. Is there some other place I should be looking for things that can affect this?

• Implementing emailing (bulk & event based) features for my website.

  - by Kabeer

  Hello. For my upcoming social networking website, I am looking for suggestions on the best way to implement emailing. Here are some of my requirements and constraints: Requirements: - Should be able to send emails based on events (new registrations, change password, etc.), promotions (advertisements based on user consent), bulk mails (newsletters), reminders (profile updates), etc. I hope I got the point through. - Should be able to process faults (incorrect email address, mail-box full, etc) - User initiated invites (inviting friends to connect) Constraints: - As of now I am looking at Godaddy for hosting. Subsequently I shall move to, may be Amazon Cloud. Godaddy seems to be excruciatingly conservative (not bad always) when it comes to the ability to send email. - My tests on Godaddy so far have been discouraging. There is limit to no. of emails I can send and sometimes if emails carries special characters it throws strange exceptions like there was a virus affected attachment (even though I hadn't attached a thing). The replies from Godaddy support have been equally funny. My intent is not to portray Godaddy as wrong but I am looking for a work-around that frees me from said constraints. I am looking for a mechanism / service that is either free of very cost effective. I wonder how other sites address this. Mine is a .Net / Windows based application.

• How can I use wildcards in an Nginx map directive?

  - by Ian Clelland

  I am trying to use Nginx to served cached files produced by a web application, and have spotted a potential problem; that the url-space is wide, and will exceed the Ext3 limit of 32000 subdirectories. I would like to break up the subdirectories, making, say, a two-level filesystem cache. So, where I am currently caching a file at /var/cache/www/arbitrary_directory_name/index.html I would store that instead at something like /var/cache/www/a/r/arbitrary_directory_name/index.html My trouble is that I can't get try_files, or even rewrite to make that mapping. My searching on the subject leads me to believe that I need to do something like this (heavily abbreviated): http { map $request_uri $prefix { /aa* a/a; /ab* a/b; /ac* a/c; ... /zz* z/z; } location / { try_files /var/cache/www/$prefix/$request_uri/index.html @fallback; # or # if (-f /var/cache/www/$prefix/$request_uri/index.html) { # rewrite ^(.*)$ /var/cache/www/$prefix/$1/index.html; # } } } But I can't get the /aa* pattern to match the incoming uri. Without the *, it will match an exact uri, but I can't get it to match just the first two characters. The Nginx documentation suggests that wildcards should be allowed, but I can't see a way to get them to work. Is there a way to do this? Am I missing something simple? Or am I going about this the wrong way?

• How to reproduce the behavior of Mac OS X's dead keys on Windows 7?

  - by Pascal Qyy

  I'm French, but I've chosen to take a QWERTY keyboard for my MacBook Pro for many reasons: first of all, the AZERTY keyboard is not at all ergonomic because it has no numeric keypad, and I must use MAJ or CAPS LOCK to access to the numeric keys ; secondly, I've bought this mac for development ; and chars {, }, etc., are not directly accessible on the Apple AZERTY keyboard the last thing is that: the diacritics are VERY easy to produce on an Apple keyboard with Mac OS X : ? + c for a ç, for example, and many dead keys easy to use (e.g. ? + e, then e give you an é. So, I have no difficulties to write in my native language with this keyboard under Mac OS X. BUT, when I boot on Windows 7's Boot Camp partition, or when I use applications from it through VMware Unity, it is no longer the same comfort! Without numeric keypad, it's impossible to use it for produce specials characters (e.g.: Alt + 0231 for the ç) I've tried many solutions, like auto replacement in Microsoft Office (e.g.: ,,c being replaced by ç), but for all my diacritics, I must type a space, then a back space before the replacement work. I've also tried third party software, as Texter, but it is very buggy and don't work properly (or don't work at all) in many case! So, is there a solution somewhere, to have this Mac OS X's nice and comfortable way of producing diacritics for Windows 7? Thank in advance for your help and your time!

• Apache Server Status page in port 8443

  - by batman

  I'm very new to apache. I tried to enable the server status page of apache. I added the status.conf and status.load to mods-enabled directory. I changed the config of apache2.conf to include all mods-enabled directory. This is the config of staus.conf: <IfModule mod_status.c> # # Allow server status reports generated by mod_status, # with the URL of http://servername/server-status # Uncomment and change the "192.0.2.0/24" to allow access from other hosts. # <Location /server-status> SetHandler server-status Order deny,allow Deny from all Allow from 127.0.0.1 ::1 # Allow from 192.0.2.0/24 </Location> # Keep track of extended status information for each request ExtendedStatus On # Determine if mod_status displays the first 63 characters of a request or # the last 63, assuming the request itself is greater than 63 chars. # Default: Off #SeeRequestTail On <IfModule mod_proxy.c> # Show Proxy LoadBalancer status in mod_status ProxyStatus On </IfModule> </IfModule> The default settings. I restarted my server. I'm redirecting all ports to 8443. Which in turn turns my requests to localhost:8443/server-status. Which does throw an 404 error. Are there any way to get around this? Thanks in advance.

• Weird rendering artefact in vim (terminal, not MacVim)

  - by Tobi Lehman

  Running Mac OS X, using either Terminal.app or iTerm2, there is a strange artefact with the character rendering that I have a hard time explaining and an even harder time understanding. I'll start with a video of my screen so that you can see and example of it in action: From the video you can see a few ways it is weird, for example, sometimes when I hit a letter in insert mode, the character is double printed. When I go into normal mode, the artefact remains. When I re-enter insert mode, hitting backspace copies the characters on the left to the position under the cursor. This has happened in OS X Lion, and Mountain Lion, under both Terminal.app and iTerm 2. This never happens under MacVim. Also, I use GNU/Linux on my other machine, and have never had this happen, I am pretty sure it is strictly a Mac OS X issue, but I do not know how to fix it. For a while, I've been working around it by using MacVim most of the time, but I prefer working in a terminal. Does anyone know what is happening here, and if so, how can I fix it? EDIT: I tried using the macvim Vim executable, and I still get strange artefacts, but they are localized to the left side of the screen, here is an example:

• sort utility on cyrillic text

  - by Anton

  I have to sort some lines of cyrillic characters and I want to use the sort utility (on MAC OS X 10.6). The problem is that result is incorrect. I take the text into clipboard, then run pbpaste | sort This is plaintext data, and I also tried passing a file to the sort command. My source data is ??????? ????? ???? ???? ?????? ??????? ???????? ?????? ? ????? ??????????????? ?????????? ???? ?????? And after sorting I get ???? ???? ???? ????? ?????? ?????? ?????? ? ????? ??????????????? ??????? ??????? ???????? ?????????? Theese lines aren’t even grouped by first letter. I tried option -d, but then I get an error sort: string comparison failed: Illegal byte sequence sort: Set LC_ALL='C' to work around the problem. sort: The strings compared were \320\321\321\321' and\320\320\320\321\321\320’. Exporting the variable as recommended doesn’t solve the problem. What can I do to use the sort utility for such a task? Any additional info is necessary?

• How to setup the Mac OS X Terminal so it's *just peachy*?

  - by kch

  Hi all, My Terminal is awesome, has every detail just right (for me anyway), and now I'm setting up a few new macs around here and I have no idea whatsoever how to get their terminals to a pretty state. My user account is rather old, has been migrated over many OS X releases and machines, so my Terminal setup has grown rather organically over the years. What I need is a recipe to start from scratch, so 1) I know what I've done, and 2) I can reproduce it anywhere. Things I'm looking for: Full UTF8 support. Setting LC_*, displaying characters correctly, accepting input… I hear this got much easier in 10.5, maybe it all works out of the box now? Setup of OS X-style keyboard text navigation (option-arrows, etc) How you particularly handle meta-key support? (other than ESC'ing your way around) Other things to help our n00bs get around in the shell, such as: List of useful default key bindings (^A, ^D, etc…) Mac-specific .profile, .inputrc goodness Mac-specific tools such as pbpaste & pbcopy, Open Terminal Here, etc If at all possible, a list of files to copy over to another machine that encompasses all the changes made to tune the Terminal. (dotrc files, plists, etc) And, well, anything else really. Just keep the scope on the Mac OS X Terminal application, rather than general unix setup and tools. I think a collection of incomplete answers would be a good start. Post one or two things you remember having done, we'll vote them up, and after a few days I'll try to compile it all into a summary answer.

• URL autocomplete no longer working in Chrome

  - by Yuji Tomita

  The browser URL autocomplete has started behaving differently starting yesterday. I used to access my top urls by typing the first one or two letters of a URL then pressing enter. Now, I have to visually fish for the right one and push the down arrow to select the url. Big difference. Anybody know if I can get the old functionality back somehow? Have I messed a setting? Example of how my browser used to work: Gmail.com: CMD + L Type G Enter Stackoverflow.com CMD + L Type S Enter Normally, the browser bar would already be highlighted with gmail.com after typing the first g. It would narrow the matches depending on what characters were typed next, or simply go to it if I pressed enter. UPDATE: I just realized my history tab looks suspicious. No entries But clearly Chrome is pulling some data from my history, as I have very personalized recommendations when typing in a letter. UPDATE: Fixed! Saved my bookmarks, removed my ~/Library/Application\ Support/Google/Default directory (careful, it looks like absolutely everything is stored here) restarted chrome, and within one visit to Gmail.com, my autocomplete was filling in my URLs like so: Beautiful.

• Discrepancy in file size on disk and ls output

  - by smokinguns

  I have a script that checks for gzipped file sizes greater than 1MB and outputs files along with their sizes as a report. This is the code: myReport=`ls -ltrh "$somePath" | egrep '\.gz$' | awk '{print $9,"=>",$5}'` # Count files that exceed 1MB oversizeFiles=`find "$somePath" -maxdepth 1 -size +1M -iname "*.gz" -print0 | xargs -0 ls -lh | wc -l` if [ $oversizeFiles -eq 0 ];then status="PASS" else status="CHECK FAILED. FOUND FILES GREATER THAN 1MB" fi echo -e $status"\n"$myReport The problem is that ls command outputs the files sizes as 1.0MB in the report but the status is "FAIL" as "$oversizeFiles" variable's value is 2. I checked the file sizes on disk and 2 files are 1.1MB. Why this discrepancy? How should I modify the script so that I can generate an accurate report? BTW, I'm on a Mac. Here is what man page for "find" says on my Mac OSX: -size n[ckMGTP] True if the file's size, rounded up, in 512-byte blocks is n. If n is followed by a c,then the primary is true if the file's size is n bytes (characters). Similarly if n is followed by a scale indicator then the file's size is compared to n scaled as: k kilobytes (1024 bytes) M megabytes (1024 kilobytes) G gigabytes (1024 megabytes) T terabytes (1024 gigabytes) P petabytes (1024 terabytes)

• Datacentre Rack naming convention with flexibility for reassignment of server roles

  - by g18c

  We are just shifting across to a new rack and until now have used names of cartoon characters. This is not going to work anymore, and need a better naming convention. Physically i would like to name the servers by location, and then have an alias as to its actual function/customer, i.e. Physical name LONS1R1SVR1 meaning London, suite 1, rack 1, server 1 Customer Alias Since the servers can be reassigned from time to time, for the above physical server name, i would have an alias as a column in a spreadsheet, that would be set to the customers host-name, i.e. wwww.customerserver1.com Patching For patching, I am looking at labeling up the physically connections, i.e. LON1S1R1SVR1-PWR1 LON1S1R1SVR1-PWR2 LON1S1R1SVR1-ETH0 LON1S1R1SVR1-KVM Ultimately if i am labeling cables, I really want to avoid putting LON1S1R1SQLSVR on any patch cord in case the server gets formatted and changed from a SQL server to a WWW server which would need to relabel all the patch cords also. In addition, throwing in virtual machines, i have got confused very quickly. I appreciated that it may be confusing having a physical host-name and customer alias. Please let me know what you run with and any other standards or best practices that i can follow?
