• When running a shell script, how can you protect it from overwriting or truncating files?

  - by Joseph Garvin

  If while an application is running one of the shared libraries it uses is written to or truncated, then the application will crash. Moving the file or removing it wholesale with 'rm' will not cause a crash, because the OS (Solaris in this case but I assume this is true on Linux and other *nix as well) is smart enough to not delete the inode associated with the file while any process has it open. I have a shell script that performs installation of shared libraries. Sometimes, it may be used to reinstall versions of shared libraries that were already installed, without an uninstall first. Because applications may be using the already installed shared libraries, it's important the the script is smart enough to rm the files or move them out of the way (e.g. to a 'deleted' folder that cron could empty at a time when we know no applications will be running) before installing the new ones so that they're not overwritten or truncated. Unfortunately, recently an application crashed just after an install. Coincidence? It's difficult to tell. The real solution here is to switch over to a more robust installation method than an old gigantic shell script, but it'd be nice to have some extra protection until the switch is made. Is there any way to wrap a shell script to protect it from overwriting or truncating files (and ideally failing loudly), but still allowing them to be moved or rm'd? Standard UNIX file permissions won't do the trick because you can't distinguish moving/removing from overwriting/truncating. Aliases could work but I'm not sure what entirety of commands need to be aliased. I imagine something like truss/strace except before each action it checks against a filter whether to actually do it. I don't need a perfect solution that would work even against an intentionally malicious script. Ideas I have so far: Alias cp to GNU cp (not the default since I'm on Solaris) and use the --remove-destination option. Alias install to GNU install and use the --backup option. It might be smart enough to move the existing file to the backup file name rather than making a copy, thus preserving the inode. "set noclobber" in ~/.bashrc so that I/O redirection won't overwrite files

• dd clone hard drive: Input/Output Error though "chkdsk" says OK

  - by unknown (google)

  Hi, I've used dd to clone hard drives before using 'dd' and a live cd, but have run into a problem. The issue: dd fails with an "Input/Output Error" on /dev/sda3 , even though windows "check disk" (chkdsk) says it's ok. Context: Trying to replace my laptop hard drive w/ a faster one of the same size Laptop has NTFS on a 320gb hard drive Booting into knoppix Knoppix recognizes 'original' drive (/dev/sda) I am using a usb connection for ‘new' drive (irrelevant, but just an fyi) Knoppix recognizes the usb drive as /dev/sdb Using dd, as follows: dd if=/dev/sda of=/dev/sdb "dd" gives the I/O error above at 82Gb (out of 320Gb) I then tried checking each partition as follows and found it failed on /dev/sda3: dd if=/dev/sda1 of=/dev/null dd if=/dev/sda2 of=/dev/null dd if=/dev/sda3 of=/dev/null I have ran windows xp chkdsk on the offending drive in both "find only" and "find and fix" mode and it reports no errors Question How can I find and fix the error on my original hard drive partition (i.e. /dev/sda3) so that dd reads it successfully?

• Are periodic full backups really necessary on an incremental backup setup?

  - by user2229980

  I intend to use an old computer I have as a remote backup server for myself and a few other people. We are all geographically separated, and the plan is to do incremental daily backups using rsync and ssh. My original idea was to make one initial full backup then never again have to deal with the overhead of doing it, and from that moment on only copy the files changed since the last backup. I've been told that this could be bad, but I fail to understand why. Since each snapshot is comprised of hard links to the unchanged files plus the original changed ones, isn't it going to be identical to a new full backup? Why would I want to make another full backup?

• How to Mirror or Clone a Spanned Volume in Windows 2008

  - by Matt

  I have a spanned volume (3x6+ TB disks spanned to one 20+ TB volume) that I need to mirror or clone to a new 20+ TB (unspanned) volume. Once mirrored or cloned I'm going to destroy the original volume and reuse the storage elsewhere. Windows 2008 will not allow me to mirror it because the original is a spanned volume. I cannot simply copy the data, because there are sparse files on the volume. So the OS thinks there is 150+ TB used on the disk when there really is only around 18TB used physically. When I try to use the copy command it won't run because it thinks the destination volume needs to be 150+ TB to hold it all. A conundrum, but I figure someone here has the answer. Thanks, Matt

• trigger a DNS change in Active directory

  - by Paddy Carroll

  Can I get solar winds to change a DNS alias in Active directory based upon a specific set of events or conditions? I have a collection of applications that use hostnames in combination with database names in order to resolve database connections, problem is that they haven't considered how a failover would work in practice so I want the product to provoke a change in DNS to point the apps at the right place if we get into a failure situation. Can it be done?

• Linux LVM snapshot commit or revert?

  - by Shewfig

  Hi, I'm about to perform an experimental upgrade on my CentOS 5 server. If the upgrade fails, I want to be able to back out the changes to the filesystem. This scenario seems similar to the example in Section 3.8 of the LVM HOWTO for LVM2 read-write snapshots - but the example is rather lacking in actual how-to. 1) How would I commit the changes, merging them back into the original partition? 2) How would I revert the changes, restoring the filesystem back to its original state? Should I assume that I'll need to restart several services, if not outright reboot? 3) Is it possible to snapshot only certain directories on a partition, or is it a partition-wide operation? Thanks...

• How to fix poor rendering in Windows Movie Maker?

  - by Cyberherbalist

  I am using CamStudio to make some instructional videos about Visual Studio for our development team, and one of the videos needed some editing to remove audio and video mistakes and to add in a better ending. CamStudio outputs to .avi files, and they look pretty good, with the program source code being quite readable. However, after making the edits using WMM, it has rendered the results to a noticeable loss in quality. It has gone from from fairly sharp in focus and adequately readable to recognizable but somewhat blurred. It has also inflated the size of the new .avi file to three times its original size (before cropping half of the vido out!). And the .wmv I attempted to render was was certainly smaller but simply horrible-looking. The left image here is the original video, and the right image is WMM's rendering in .avi format: I have to be doing something wrong, but I know nothing about how to use WMM (my first use of it). I am using default settings to the best of my knowledge. Any suggestions welcomed!

• VBA + Polymorphism: Override worksheet functions from 3rd party

  - by phi

  my company makes extensive use of a data provider using a (closed source) VBA plugin. In principal, every query follows follows a certain structure: Fill one cell with a formula, where arguments to the formula specify the query the range of that formula is extended (not an arrray formula!) and cells below/right are filled with data For this to work, however, a user has to have a terminal program installed on the machine, as well as a com-plugin referenced in VBA/Excel. My Problem These Excelsheets are used and extended by multiple users, and not all of them have access to the data provider. While they can open the sheet, it will recalculate and the data will be gone. However, frequent recalculation is required. I would like every user to be able to use the sheets, without executing a very specific set of formulas. Attempts remove the reference on those computers where I do not have terminal access. This generates a NAME error i the cell containing the query (acceptable), but this query overrides parts of the data (not acceptable) If you allow the program to refresh, all data will be gone after a failed query Replace all formulas with the plain-text result in the respective cells (press a button and loop over every cell...). Obviously destroys any refresh-capabilities the querys offer for all subsequent users, so pretty bad, too. A theoretical idea, and I'm not sure how to implement it: Replace the functions offered by the plugin with something that will be called either first (and relay the query through to the original function, if thats available) or instead of the original function (by only deploying the solution on non-terminal machines), which just returns the original value. More specifically, if my query function is used like this: =GETALLDATA(Startdate, Enddate, Stockticker, etc) I would like to transparently swap the function behind the call. Do you see any hope, or am I lost? I appreciate your help. PS: Of course I'm talking about Bloomberg... Some additional points to clarify issues raise by Frank: The formula in the sheets may not be changed. This is mission-critical software, and its way too complex for any sane person to try and touch it. Only excel and VBA may be used (which is the reason for the previous point...) It would be sufficient to prevent execution of these few specific formulas/functions on a specific machine for all excel sheets to come This looks more and more like a problem for stackoverflow ;-)

• Problem with custom 404 page

  - by user33687

  Don't know if this question is appropriate here. I created an Alias directed to the root folder of the website (right now running on localhost). In the root folder, I have a custom 404 page, and I've added a .htaccess file in that folder with the "ErrorDocument 404 /404.html" line, but it still doesn't work. I'm pretty new to this stuff (web servers), so I must be missing something obvious. Any suggestions greatly appreciated.

• Hybrid gmail MX + postfix for local accounts

  - by krunk

  Here's the setup: We have a domain, mydomain.com. Everything is on our own server, except general email accounts which are through gmail. Currently gmail is set as the MX record. The server also has various email aliases it needs to support for bug trackers and such. e.g. [email protected] |/path/to/issuetracker.script I'm struggling with a setup that allows the following, both locally and from user's email clients. guser1 - has a gmail account and a local account guser2 - only has a gmail account bugs - has a pipe alias in /etc/aliases for issue tracker Scenarios mail to [email protected] from local host (crons and such) needs to go to gmail account mail to [email protected] from local host mail to [email protected] needs to be piped to the local issue tracker script So, the first stab was creating a transport map. In this scenario, the our server would be set as teh MX and guser* destined emails are sent to gmail. Put the gmail users in a map like so: [email protected] smtp:gmailsmtp:25 [email protected] smtp:gmailsmtp:25 Problems: Ignores extensions such as [email protected] Only works if append_at_myorigin = no (if set to yes, gmail refuses to connect with: E4C7E3E09BA3: to=, relay=none, delay=0.05, delays=0.02/0.01/0.02/0, dsn=4.4.1, status=deferred (connect to gmail-smtp-in.l.google.com[209.85.222.57]:25: Connection refused)) since append_at_myorigin is set to no, all received emails have (unknown sender) The second stab was to set explicit localhost aliases in /etc/aliases and do a domain wide forward on mydomain. This too requires setting the local server as the MX: root: root@localhost # transport mydomain.com smtp:gmailsmtp:25 Problems: * If I create a transport map for a domain that matches "$myhostname", the aliases file is never parsed. So when a local user (or daemon) sends an email like: mail -s "testing" root < text.txt Postfix ignores the /etc/alias entry and maps to [email protected] and attempts to send it to the gmail transport mapping. Third stab: Create a subdomain for the bugs, something like bugs.mydomain.com. Set the MX for this domain to local server and leave the MX for mydomain.com to the Gmail server. Problems: * Does not solve the issue with local accounts. So when the bug tracker responds to an email from [email protected], it uses a local transport and the user never receives the email. % postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_at_myorigin = no append_dot_mydomain = no biff = no config_directory = /etc/postfix inet_interfaces = all mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 mydestination = $myhostname, localhost.$myhostname, localhost myhostname = mydomain.com mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname readme_directory = no recipient_delimiter = + relayhost = smtp_tls_cert_file = /etc/ssl/certs/kspace.pem smtp_tls_enforce_peername = no smtp_tls_key_file = /etc/ssl/certs/kspace.pem smtp_tls_note_starttls_offer = yes smtp_tls_scert_verifydepth = 5 smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtp_use_tls = yes smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) smtpd_recipient_restrictions = permit_mynetworks, reject_invalid_hostname, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_unauth_destination smtpd_tls_ask_ccert = yes smtpd_tls_req_ccert = no smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache tls_random_source = dev:/dev/urandom transport_maps = hash:/etc/postfix/transport

• Why is hibernation still used?

  - by Moses

  I've never quite understood the original purpose of the Hibernation power state in Windows. I understand how it works, what processes take place, and what happens when you boot back up from Hibernate, but I've never truly understood why it's used. With today's technology, most notably with SSDs, RAM and CPUs becoming faster and faster, a cold boot on a clean/efficient Windows installation can be pretty fast (for some people, mere seconds from pushing the power button). Standby is even faster, sometimes instantaneous. Even SATA drives from 5-6 years ago can accomplish these fast boot times. Hibernation seems pointless to me when modern technology is considered, but perhaps there are applications that I'm not considering. What was the original purpose behind hibernation, and why do people still use it? Edit: I rescind my comment about hibernation being obsolete, as it obviously has very practical applications to laptops and mobile PCs, considering the power restrictions. I was mostly referring to hibernation being used on a desktop.

• grep - what arguments do you usually specify?

  - by meder

  My most common grep line is just.. grep -IRl "text" * However I'm kinda getting tired of retyping this over and over - is there some way I can make an alias command so that those arguments are always enabled? And, I was wondering what arguments you usually specify for text searching - my two arguments 'R' for recursion, 'I' for not including binary types like jpg/gif, and 'l' for line number seem a bit too minimal. Which arguments do you use?

• Problems with mailenable when sending to yahoo

  - by Naresh

  I m testing sending emails from mailenable webmail. I have no problems sending mail to gmail or hotmail, both work fine, but yahoo mail shows the attachment icon for the message even though the message doesn't contain any attachments, it's just plain text. It only includes a reply to a previous message, like this: message text ----- Original Message ----- original message text I copied the message content and sent it from gmail to yahoo and the attachment icon didn't show which makes me believe it's something with mailenable. What could possibly be wrong? Also, is there a white list for yahoo mail that I can join? And also for other popular webmail? I'm going to use this on a production website (site visitors use the contact us form to send messages to the site - the mail enable server running on the same machine as the web server - then I check the messages using the mailenable webmail and reply them). This is really important to me, your help would be really appreciated ...

• how to copy sql server database on same server

  - by Sam

  I've got a SQL Server 2008 and want to make a copy of a database so I've got a 2nd Version of the database for testing on the same server. The database copy wizard is not able to copy the database, it always sends funny error Messages about missing objects (using SMO copy). When I try to make a backup and restore it under a different database name it still keeps the file names of the original database and overrides this (crashing the original database). So how do I copy a SQL database? Shutdown SQL Server, copy the physical files and attach them? Maybe a command line tool for database copy? Shouldn't there be an easy way to make a copy?

• Can I make scp ask before overwriting an existing file?

  - by Boldewyn

  Is there a possibility (man scp didn't reveal any) to make scp interactive like cp -i? That is, scp asks, if the target exists, if it may overwrite it? If yes, does it work locally and remote? If no: Let's alias it! But I hope for a simpler solution.

• Batch Convert .mkv to .mp4 with VLC

  - by IamHere

  i want to batch convert all .mkv file in a folder into .mp4 with vlc. it should use the original video-/audio-stream and if possible the .ass subtitle of the .mkv. so its not really a convert, its more changing the container. (my player cant read the mkv) if i do this conversion by hand (manually) it works, but i have a lot of mkv to convert, so it would take a lot of time. i have searched the internet for a batch file to do this and i found a few and tried to modify them to my wish, but all attempts i tried just created a .mp4 file that doesn't contain the audio-stream and the video-stream also cannot be rendered by all my mediaplayers on the pc. so i would be very thankful, if you could tell me how the batch have to look like, so it works with original video-/audio-stream (maybe .ass subtitle)

• How do I make a partition usable in windows 7 after power loss?

  - by user1306322

  A few days ago I was installing some software and power went down. When I rebooted, the partition to which the software was installed was not accessible. Disk manager shows that it's there, but doesn't show type, if it's healthy and gives me an error when trying to read its properties. The problem seems to be common after power loss, people recommend solving it by assigning a letter to the partition via DiskPart utility, but partition isn't listed in my case. I can access that partition with bootable OSs (like bootable Ubuntu or winXP) and all the files are there, but another installation of Windows 7 gives me the same results as the original. I could just copy all data to another disk if there was enough space, but unfortunately the size of partition I'm having problems with is 1.1TB. How do I regain access to the partition in my original Windows 7 installation without losing any data?

• proxy software that supports parallel transfer

  - by est

  Hi guys, I need to setup a really fast proxy server in a remote server, here's the scenario: The server prefetches 3KB of data, mostly HTTP resources. The server send to client 3KB of data, instead of traditional HTTP or SOCKS proxy, the server open multithreaded transfer with 3 connections, send 1KB of data per thread to each connection The client receives 1KBx3, and combine them to the original 3KB data, and return as a local HTTP proxy server. The client display the original data in browser via the local HTTP proxy The latency is not important as long as the transfer rate is good. Does any software like this exist? It's better if it's open source or free ones.

• Why do I sometimes get 'sh: $'\302\211 ... ': command not found' in xterm/sh?

  - by amn

  Sometimes when I simply type a valid command like 'find ...', or anything really, I get back the following, which is completely unexpected and confusing (... is command name I type): sh: $'\302\211...': command not found There is some corruption going on I think. I don't use color in my prompt, I am using the Bash shell in POSIX mode as sh (chsh to /bin/sh and so on - $SHELL is sh). What is going on and why does this keep happening? Anything I can debug? I think this is more of an xterm issue than sh, or at least a combination of the two. Files, for context: My /etc/profile, as distributed with Arch Linux x86-64: # /etc/profile #Set our umask umask 022 # Set our default path PATH="/usr/local/sbin:/usr/local/bin:/usr/bin" export PATH # Load profiles from /etc/profile.d if test -d /etc/profile.d/; then for profile in /etc/profile.d/*.sh; do test -r "$profile" && . "$profile" done unset profile fi # Source global bash config if test "$PS1" && test "$BASH" && test -r /etc/bash.bashrc; then . /etc/bash.bashrc fi # Termcap is outdated, old, and crusty, kill it. unset TERMCAP # Man is much better than us at figuring this out unset MANPATH My /etc/shrc, which I created as a way to have sh parse some file on startup, when non-login shell. This is achieved using ENV variable set in /etc/environment with the line ENV=/etc/shrc: PS1='\u@\H \w \$ ' alias ls='ls -F --color' alias grep='grep -i --color' [ -f ~/.shrc ] && . ~/.shrc My ~/.profile, I am launching X when logging in through first virtual tty: [[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && exec xinit -- -dpi 111 My ~/.xinitc, as you can see I am using the system as a Virtual Box guest: xrdb -merge ~/.Xresources VBoxClient-all awesome & exec xterm And finally, my ~/.Xresources, no fancy stuff here I guess: *faceName: Inconsolata *faceSize: 10 xterm*VT100*translations: #override <Btn1Up>: select-end(PRIMARY, CLIPBOARD, CUT_BUFFER0) xterm*colorBDMode: true xterm*colorBD: #ff8000 xterm*cursorColor: S_red Since ~/.profile references among other things /etc/bash.bashrc, here is its content: # # /etc/bash.bashrc # # If not running interactively, don't do anything [[ $- != *i* ]] && return PS1='[\u@\h \W]\$ ' PS2='> ' PS3='> ' PS4='+ ' case ${TERM} in xterm*|rxvt*|Eterm|aterm|kterm|gnome*) PROMPT_COMMAND=${PROMPT_COMMAND:+$PROMPT_COMMAND; }'printf "\033]0;%s@%s:%s\007" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"' ;; screen) PROMPT_COMMAND=${PROMPT_COMMAND:+$PROMPT_COMMAND; }'printf "\033_%s@%s:%s\033\\" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"' ;; esac [ -r /usr/share/bash-completion/bash_completion ] && . /usr/share/bash-completion/bash_completion I have no idea what that case statement does, by the way, it does look a bit suspicious though, but then again, who am I to know.

• HOWTO Catch/Redirect all outgoing e-mails from webapp on Windows Server 2003

  - by John

  As suggested by another member, I have split the original post into two. To see the original post, go to http://serverfault.com/questions/134595/howto-catch-redirect-all-outgoing-e-mails-on-win2k-and-redhat-enterprise. For this question, please keep your answers specific to Windows Server 2003 only. Thanks for the help in advance. Background: I am integrating two separate web application that are developed in ASP .NET and JSP/Struts. As such, they are hosted on two different server technologies, namely Win2K3 and Redhat Enterprise Server 5.5. Problem: There is a copy of production data in my test environment with real e-mail addresses. I need to test the e-mail functionality of these applications, but I do not want them to send out actual e-mails. Is there a way to catch and redirect all outgoing e-mails? Ideally, I would like to send all outgoing e-mails to another e-mail (i.e., [email protected]) so my testers can look at them.

• Conflicts with MS Office temporary files when using Offline Folders on Vista

  - by Tambet

  We are using Offline Folders feature of Windows Vista to make files on network shares available when out of office. Mostly it is working, but every time I do a sync I get a lot of such errors: D500E7B8.tmp - A file was deleted on this computer and changed on the server while this computer was offline. There are hundreds of them. I always select all of them and choose resolution "Delete from both locations". But what is causing this and how can I avoid it? I suspect the reason is that we are using Debian and Samba (3.4.7) on our file server. I've been looking for some Samba options that would cure this, but with no success. I learned that probably the cause is, that both Word and Excel are using specific pattern to change files - they never change the original file, but instead always write a new temporary file and rename it to original file, when you click Save. This is documented here: http://support.microsoft.com/kb/211632/?FR=1.

• e-mail no longer coming to aol inbox since I opened a Hotmail account [closed]

  - by Dave

  I recently set up an email account with Hotmail. I have used AOL e-mail for years and would like to keep this as my main source for sending/receiving e-mail. When I set up the Hotmail account there was an option to have all my e-mail accounts forwarded to the Hotmail inbox. I set up this option and the page promised that all incoming mail would still be visible in the original inbox, in this case my AOL account. Well everything does come to the Hotmail account, the only problem is that I no longer receive these e-mails in my primary/desired location which is AOL. I went back and made sure the box was checked that provided the option through Hotmail that said "leave a copy of my messages on the server" (AOL) How do I get the e-mail that is being forwarded to Hotmail from my AOL account to still be visible in AOL, it should be in AOL inbox as that is the original destination but it is gone. Suggestions?
