• Looking for an open source email archiving application

  - by Joel

  I'm looking for an open source application that will archive my email. It might do this by logging in to my POP3 account on a regular basis and copying the emails across, or it might just read my Unix mbox/maildir file/directory directly on the mail server. It must be open and it must run on Linux (or any open OS actually). Ideally, it would have a web interface, but this is not a major requirement. MXsense (http://www.mxsense.com/mxsense.html) seems to be pretty-much what I want, except it's not open. I have no requirement for MS Exchange support. Any suggestions? The rationale (maybe a bit silly) is that I run Linux exclusively and it's still doesn't have an email client that is anywhere close to MS Outlook in terms of awesomeness, so I find myself switching between mail clients often. I would feel better about this if I had an archive of my emails, so it wouldn't matter which mail client I was using this month.

• Formatted mac external hard drive loaded on pc

  - by kjokay

  I have an issue where it appears that an external hard drive which had been formatted on a mac system was loaded as a drive in Windows. Windows is obviously unable to read the data and now the drive won't mount in the mac. It appears that Windows overwrote something concerning the drive's information on what filesystems and types it has on it. Mac diskutility is unable to repair the drive and the partition is showing up in the utility as a FAT32. Using an applexsoft utility, I am able to verify the data is still on this drive, but I'd rather not spend $100 to save these files (its not my hard drive anyways). Is there a way I can use some UNIX commands to find out the partition information on the drive, back the raw data up on it, then restore the data back onto the drive after re-formatting it again?

• Mac OS X bash: uninstall all apache and PHP occurences

  - by fireeyedboy

  Hi all, How do I find all installed apache and PHP occurences on a Mac OS X system in bash and uninstall them? My motivation: I've managed to install multiple apache and PHP packages (I believe it's called packages in Unix terms, correct?) at some point, and I'ld like to start out fresh again, without completely re-installing Mac OS X again. Also, I'ld like to install suPHP along with apache this time, and I believe I need to compile apache with some additional stuff for that. But that is a challenge I'll deal with later, and probably ask a question about then. :) Thank you in advance for your info.

• How does Mac's command line compare to Linux?

  - by Nathan Long

  I love Ubuntu Linux - especially the commmand line. But I have to admit that, at least for now, Windows is more user-friendly - there's more software for it, more drivers, and more stuff just works. Knowing that Mac is built on Unix makes me wonder if it's the sweet spot between them. But I wonder: how similar is the Mac command line to Linux's bash? Could I pick right up with using vim and bash scripting and git, etc? Would common commands like changing directories be different? Does anybody know an online "compare and contrast" resource?

• NETAPP Fragmentation

  - by mdpc

  We all know that once a disk (or storage system for that matter) gets introduced into use, the performance degrades due to fragmentation of files. This seems to be why disk defragmentors are in fairly wide use on Windows boxes. And they do increase the performance substancially. As an aside, I haven't heard of many defragmentors in the Unix/Linux area. Despite the claimed WAFL protections for the NetApp, file fragmentation still will occur, especially with all the sparsely crated VMs. My question is does anybody do any sort of defragmention of such a storage system? Do you notice any measurable degration/improvement of either not doing/doing anything to address this situation? Does anybody do anything about it? If so what? Thanks

• How to find out what is installed on a server

  - by masfenix

  Hi, im an undergrad student and we have special access to a server. The server is a unix server (dont know the OS or anything.. is there a way to find out? ). we also get a website associated with the server. There is a public_html folder. I uploaded with a test file with phpinfo() but the server didnt parse it (yes i had the right extension) . So im guessing PHP isnt installed. is there a way to see what "common" languages ARE installed?

• Editing sudoers file to restrict a user's commands

  - by devin

  Is it possible to edit the sudoers file so a user can use sudo for any command except for a specified one? I reverse is true, I believe, that the sudoers file can be setup so that a user can only execute a given list of commands. EDIT: the commands I really want to take away are halt and reboot... this makes me think there are special system calls for halt and reboot. Can you take system calls away from a user? If not, is it because the unix permission system abstracts over system calls neglecting this?

• Screen startup apps

  - by stillinbeta

  I know that most people don't bother with things like screen anymore, but I happen to really like it, even in this GUI day and age. I still do most of my development from a BASH prompt, so it's extremely useful to me. What I'm wondering is what the easiest way is to start an instance of screen (stored in a shell script or .screenrc or somewhere else) so that it starts up with set commands already running in set windows. For example, I use a django test server, so I'd like one window to come up running "python manage.py runserver" and another blank, waiting for commands. The man page is wholly indecipherable. These old unix utilities can do quite nearly everything, so I'm sure this is possible, but I can't for the life of me figure out how. I

• Next generation of command shells?

  - by ignatius

  I am curious about if there is any project about a replacement for the current unix-shells (like bash, ash, rsh ...), at least adding some new ideas or paradigm in this area. I was searching but i found very few information, this project http://en.wikipedia.org/wiki/Friendly_interactive_shell seems interesting, but not so diferent from the nowadays solutions. What do you think? Do you imagine a linux-distribution on 2020 that still having bash? How can be an evolution of this programs? Br To be clearer, about new ideas, i was talking of something like: control-Z functionality Colaboration features (like remote desktop) so you can invite someone to join and participate on your shell session Possibility to see the result of a command before to really apply it to your system (this is closely related with the 1st point ctl-Z) etc...

• recipient_delimiter in MS-Exchange

  - by guettli

  Most UNIX mail server support recipient delimiters behind a plus sign in email addresses. [email protected] In the above example "everything" could be any string, and the mail should get into the mail box of the user "user". In postfix it is called recipient_delimiter: http://www.postfix.org/postconf.5.html#recipient_delimiter Is this possible with Exchange 2010? Usecase1: The user can use different email addresses. He can use [email protected] for the communication with "fooshop". If he gets spam mail to this address later, he knows that fooshop has given his address to someone else. Usecase2: We run a ticket system ( http://tbz-pariv.de/software/modwork/ ) and want to add send scans via email to the system. The network scanner can only modify the to-address and we want to insert the ticket type like this [email protected]

• Windows 7 Stopped Using hosts file for DNS Resolution

  - by AJ

  I am running Windows 7 Home Premium 64-bit. Starting today, I noticed that DNS resolution is not reading my %SYSTEMROOT%\System32\drivers\etc\hosts file. I say this because I added two new entries to the file and when I run 'nslookup' on the command line, they don't resolve. Further, just trying to resolve 'localhost' results in my primary DNS server being queried. I've read several threads that suggest that the file might have been corrupted and to move it aside and create a new one. I've done that, and no improvement. Is there some sort of registry key that controls the sequence of resources used for DNS resolution (similar to nsswitch.conf on UNIX)? What else could be causing this? Thanks in advance.

• g++ in Knoppix 6 LiveCD

  - by HazyBlueDot

  To avoid the inevitable, let me put this in context. I am instructing an Intro to Unix course this semester and the students are using Knoppix 6.4.3 off the LiveCD. They are not required to install the system to their hard drive, and I would like to not require them to, however they do have use of a USB flash drive. This version of Knoppix seems to include gcc, but NOT g++. The course curriculum requires compiling C++ programs. I know I can run: sudo apt-get update sudo apt-get install build-essential to install (among other things) g++, but of course this only makes sense on a system installed to a hard drive. So my question is, can I write a script that calls gcc with appropriate options and flags to compile a C++ program that students could use in place of g++?

• Custom prompt doesn't work on Mac's terminal

  - by mareks

  I like to use a custom prompt (current path in blue) on my unix machine: export PS1='\[\e[0;34m\]\w \$\[\e[m\] ' But when I try to use it on Mac's terminal it doesn't work: it fails to detect the end of the prompt and overwrites the prompt when I type commands. This also happens when I'm inputting a long command where it wraps over the same line instead of starting a new line. I don't understand why this is the case since I use bash on both machines. Any suggestions on how to remedy this?

• ICMP Data Field Modified - What does it Mean?

  - by Lucretius

  Normal ICMP Data fields are composed of a pretty standard 32 byte string of alphabet characters. abcdefghijklmnopqrstuvwabcdefghi I have captured a series of ICMP echo requests using WireShark with a modified Data field and I have no idea what it means. (Underscores represent spaces.) abcdefghijklmnopprstuvwxyzabcdefghi abcdefghijklmnoparstuvwxyzabcdefghi __abcdefghijklmnopsrstuvwxyzabcdefghi __abcdefghijklmnopsrstuvwxyzabcdefghi __abcdefghijklmnopwrstuvwxyzabcdefghi __abcdefghijklmnopdrstuvwxyzabcdefghi__ Note: The position of the "q" character The addition of "xyz" The addition of spaces before and after the payload When you look at the position of "q" horizontally it spells "passwd" which is a Linux/Unix command for changing a users password. Any ideas?

• An SQLite/STDIN Conundrum, Specific to AIX

  - by mikfreedman

  Hi there! I'm been playing around with SQlite at work, specifically with trying to get the sqlite3 command line tool to accept stdin instead of a file. Sounds easy enough, on linux you can execute a command like: echo 'test' | sqlite3 test.db '.import /dev/stdin test' unfortunately - our machines at work run AIX (5 & 6) and as far as I can tell, there is no equivalent to the virtual file /dev/stdin. I managed to hack together an equivalent command that works on AIX using a temporary file. echo 'test' | cat - > /tmp/blah ; sqlite3 test.db '.import /dev/stdin test' ; rm /tmp/blah Now, does it need to use STDIN? isn't this temporary file thing enough? Probably, but I was hoping someone with better unix-fu had a more elegant solution. note: the data I would like to import is only provided via STDOUT, so that's what the echo 'test' command is all about

• Can I use PLink and Pageant with Cygwin's ssh?

  - by Jerph

  I'm now using msysgit because of the GUI tools, which use Putty's Pageant and PLink utilities, but I use Cygwin as a general SSH terminal. I had been using ssh-agent on Cygwin, but that means I have to enter my SSH key passphrases for both SSH key managers. Is it possible to configure all my Unix-port tools (msys, git, cygwin, Ruby Net:SSH, etc.) to use PLink/Pageant instead of ssh-agent? It seems that's the kind of thing PLink was made for, but I can't find documentation on how.

• Mouse cursor in Terminal?

  - by marienbad

  I use Mac OS X Terminal.app. But the answer to this would probably apply to any typical UNIX-ish terminal emulator in a graphical environment. Question -- what do I do to: Use my mouse cursor to click on a character-position in the current line of the terminal, and have the terminal's cursor jump to that spot? Typically, you have to hold down an arrow key to move to the correct cursor position. If you're pasting in a long string of text at the shell prompt, or working in an editor like VI, this can take a long time. I know editors have other navigation keys like jump-words, but I like my mouse cursor.

• Windows screen shots via command-line SSH session

  - by Geoff Fritz

  I've browsed the handful of "screen capture" queries here, but I was unable to find anything which addressed my specific need. I'm looking for a command-line tool that I can run via remote SSH connection (by way of the cygwin sshd daemon). There are several to choose from, but the few I've tried (ImageMagick, nircmd, and MiniCap) all result in a blank screen. I assume that this is due to the remotely logged in user not having a proper graphical console session running. The goal here is automate screen capture and retrieval of the main system console (what one would see if they were looking at the physical monitor) through the use of ssh script from a Unix host: ssh user@windowshost "screencap --output /tmp/console.jpg" scp user@windowshost:/tmp/console.jpg /some/destdir Note that these must be done on demand, so polling a remote directory that has snapshots dumped periodically will not work. Bonus points for programs that are open source and have a portable install (so I don't need to RDP/VNC into the machine to run a graphical installer).

• Managing DroboShare SSH usernames and passwords

  - by user17067

  The default login for SSH on the droboshare is a user name of root with a password of giveit2me. With the command passwd the password can be changed. However I can't find anyway to change the default user name. Since any Unix based has a user named root this kinda bugs me as a minor security issue. Does anyone know how to change the user name for droboshare SSH logins? The SSH program being used is a variant of dropbear if that is any help.

• How can I convert an OpenOffice document to PDF from the Linux command line?

  - by Norman Ramsey

  I have students who, when asked for PDF, sometimes hand me an OpenOffice document or spreadsheet. file(1) can identify these documents, but I've been unable to discover how to convert them to PDF using the command line. (The man page for ooffice(1) lists an option to print a document but not to convert to PDF.) Google is unhelpful, except for giving me the uneasy feeling that this can't be done without a nifty script in a language I don't know against an API whose documentation I can't find. Can anyone help me solve the problem of converting an OpenDocument to PDF using only the Unix command line?

• Nginx RegEx to match a directory and file
