• Multiple redirects / rewrites within one VirtualHost group

  - by Benjamin Dell

  Hi, I have a client that now wants to point a couple of dozen urls to their main site. I have added them as serveralias's in the sites apache config file... so now all of these urls point to the primary one... excellent. The problem i have is that if ANY of these alias's are accessed at the root (i.e. www.domain.com rather than www.domain.com/some-page/) then i need to redirect them to a specific page within the site (i.e. anyone accessing domain.com might need to be sent to domain.com/special-landing-page/). However, any visit to anything other than the landing page should just continue as normal without any re-directs. I've been battling with this for a few hours and can't seem to find the best solution. Does anyone have any suggestions?

• Debian/Ubuntu apt or pbuilder without root privileges?

  - by Tem Pora

  I want to use apt or pbuilder to build a package in user's home directory. The home directory has enough space to hold the package's source, its dependencies and binary output. But the apt and pbuilder documents say that you have to be a root user (sudo) to use it. It's frustrating, as the only way now I have at my disposal is to build the package from source or use the dumba$$ (sorry for bad language) dpkg and in both cases figure out every dependency manually, create the dir layout manually and install the built things manually. Now if I can do all these things manually, why the tool writers (apt) think that doing so using their tool (apt) is somehow more special/dangerous? I don't want to use root privileges JUST to build and test a user-land package. If I am NOT allowed to do anything outside my home dir then why NOT the apt or pbuilder type commands be allowed to "build" something in my home dir without root privileges? I just want to use their functionality. It seems there is nothing like Gentoo Prefix from Debian

• Taking user out of MACHINENAME\Users group does not disallow them from authenticating with IIS site

  - by jayrdub

  I have a site that has anonymous access disabled and uses only IIS basic authentication. The site's home directory only has the MACHINENAME\Users group with permissions. I have one user that I don't want to be able to log-in to this site, so I thought all I would need to do is take that user out of the Users group, but doing so still allows him to authenticate. I know it is the Users group that is allowing authentication because if I remove that group's permissions on the directory, he is not allowed to log in. Is there something special about the Users group that makes it so you are actually always a part of it? Is the only solution to revoke the Users group's permissions on the site's home directory and grant a new group access that contains only the allowed users?

• MS Excel find and replace macro

  - by william

  I have written a macro to remove special characters in a sheet based on ascii values but the problem with it is that it is replacing the cell content. For example p;j;h which should become p,j,h is becoming ,, (missing the data). Do I need to include any additional statements, or how else to adjust my code? sub specialcharecters() Dim i As Long For i = 32 To 43 Selection.Replace what:=Chr(i), replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False Next i Selection.Replace what:="~*", replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False For i = 45 To 47 Selection.Replace what:=Chr(i), replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False Next i For i = 58 To 64 Selection.Replace what:=Chr(i), replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False Next i For i = 123 To 125 Selection.Replace what:=Chr(i), replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False Next i Selection.Replace what:="~~", replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False END sub

• Visual Studio 2010: Is it possible to force editor to use ANSI rather than UTF-8?

  - by Mark Redman

  I am having issues with some files in automated processes, specifically with batch files and sql files. Visual Studio seems to create these as UTF-8 rather than ansi and adds some kind of special characters to the beginning of the file (I think this is a called a pre-amble) This breaks running batch files and running swl files through osql.exe. I have had issues myself in the past in creating text files using C#, but can get around that through encoding. However its seems a bit strange I cant use Visual studio to create batch files and sql files in a database project for automation.

• Encrypting a single File with password and keyfile

  - by Ctroy

  I am a fan of True Crypt and I guess it's the best encryption tool available. As far as I understand, True Crypt created encrypted containers which acts a place to store files. But I would like to encrypt a single file. Preferably with a password and a special key file (like in truecrypt). It would be great (but not mandatory), if the file doesn't require any third party software to encrypt and decrypt, in the sense that I provide the password and key to the file directly. Thanks in advance.

• Home Directory Folders

  - by George

  I am looking for a way to acomplish the following: Currently users have home drives mapped via AD profile as follow: \\fileserver\users\username However if once a user was able to access \\fileserver\users and view everyones folder, but had no access to them. This is not ideal since we have people saving important stuff to on their drives. How can I restrict users permissions and views only to THEIR home drives? I also saw this solution, but not sure if it would apply to me: ================================================================================ Share level permissions - Everyone full permission and remove all others On the file/folder level set the following: Authenticated users special permissions on the root of the \\server\homeshare\ to Check the boxes next to the following: Traverse folder / execute file List Folder / read data Read attributes Read extended attributes / List item All other boxed leave unchecked and make sure you apply "This Folder Only" Domain Adminsfull rights and apply “this folder, subfolders, and files” This will block the users from accessing other user home directories. When you create the new user and set the home directory it will create the folder for you with the correct permissions.

• OS X: What does the '@' attribute on a file mean?

  - by claytontstanley

  On a Snow Leopard machine, at the Terminal: la ~/src/rmcl/ | grep RMCL -rw-r--r--@ 1 claytonstanley staff 6766167 Nov 13 2009 RMCL What is that '@' attribute? This file is part of an older OS X program that runs under Rosetta. I'm having issues where some older programs running under Rosetta require the @ attribute when opening files. But I'm not sure what that attribute is, so I have no way to know how to add/remove it. I did try a thorough Google search on this, but I wasn't able to find the answer. I would have thought this would be an easy one to find. Maybe the Google query isn't acting properly because of the single @ special character. Any info. is much appreciated. Thanks!

• Ubuntu 12.04 issue installing Webmin modules (file does not exist)

  - by Arthur

  I'm running ubuntu 12.04. On this machine I have Webmin 1.580 installed. When trying to add a new module to Webmin I receive an error: "Failed to install module from : File does not exist" This happens when i go to Webmin Configuration Webmin Modules Select "Third party module from" Select "OpenVPN admin tool" and clicking on install module After I selected "OpenVPN admin tool" this url is being added: http://www.openit.it/downloads/OpenVPNadmin/openvpn-2.5.wbm.gz This URL resolves to a correct file. When uploading the file directly, the same error occurs. In the log file: /var/webmin/webmin.log nothing special is reported. How can I fix this issue? P.s. I run this server in CLI mode

• Advanced imap search with alpine?

  - by devnull

  I am using alpine since a few days and I am very happy with the IMAP functionality and the terrific speed. The only frustration is that the W search (whereis) isn't as powerful (and probably not meant to be). What would be the best solution to search all inbox messages e.g. with a specific from (and having alpine to show a list of these matching messages) or even in the entire collection of IMAP folders or in a specific IMAP folder (e.g. archive) ? I think this might need a special script

• Reverse Proxy to filter out js files from multiple hosts in nginx

  - by stwissel

  I have a website http://someplace.acme.com that I want my users to access via http://myplace.mycorp.com - pretty standard reverse proxy setup. The special requirement: any js file - either identified by the .js extension and/or the mime-type (if that is possible) text/javascript needs to be served from a different location, a local tool that inspects the js for potential threats. So I have location / { proxy_pass http://someplace.acme.com; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504; proxy_redirect off; proxy_buffering off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location ~* \.(js)$ { proxy_pass http://127.0.0.1:8188/filter?source=$1; proxy_redirect off; proxy_buffering off; } The JS still is served from remote and I have no idea how to check for the mime type. What do I miss?

• suddenly cannot mount nfs share from windows 7

  - by bing

  I recently reinstalled my file server (moved from fedora to ubuntu server). Now I cannot mount my nfs share from windows 7, mounting from mac osx works fine. In windows I either keep getting "the semaphore timeout period has expired" or "an unexpected error has occured". Does ubuntu need some special magic to allow windows 7 to mount an nfs share? This is my exports file /home/bing/ 192.168.1.*(rw,async,insecure,no_subtree_check) /home/bing/mnt/EXTRN2 192.168.1.*(rw,async,insecure,no_subtree_check) /home/bing/mnt/EXTRN3 192.168.1.*(rw,async,insecure,no_subtree_check)

• Custom Rule Sets in JohnTheRipper

  - by user854619

  I'm trying to create a custom rule set to do hash cracking. I have a SHA1 hash and a rule set that was enforced to create the password. The password must be of the form, 6-8 characters Every other letter changes case Password "shifts" characters at least one degree and at most three One odd number and one even number are at the beginning of the password One special character and one punctuation character are appended to the end of the password How can I defined a brute force attack in JohnTheRipper or similar hash cracking program? I've also attempted to write code to generate a wordlist of possible passwords, with no success. Thanks!

• Empty mails received from Plesk-driven server

  - by goreSplatter

  From my Plesk managed server I keep receiving emails addressed to the configured administrator (me). Nothing special there. These mails are sent from an empty sender with no body, no subject nor any other relevant headers. I have changed the server administrator's e-mail address to an alternate one which is then the recipient. The mails are sent at irregular intervals. With variations in the timestamp I get an email every 30 minutes. Then there's a break and two and a half hours later I get the same email. I already have turned of crond for more than a day to see if this is the source of the problem. On that server there is no "foreign" software running which would cause that behavior. I have no more guesses as to why this is happening. Any suggestions?

• Possible to redirect from HTTPS to HTTP behind load-balancer?

  - by Derek Hunziker

  I have a basic ASP.NET application that sits behind an F5 load-balancer. Incoming SSL requests (over HTTPS) terminate at the load-balancer and all internal communication between the load-balancer and my application servers is unsecure (over HTTP). When a unsecure request comes in, my app is able to use Response.Redirect("https://...") to redirect a secure URL with no problems. However, the other direction appears to be impossible - I cannot redirect from HTTPS to HTTP using Response.Redirect() from my application. The URL remains HTTPS for the client and does not change. Could the F5 be preventing the redirect for ever reaching the client? Is there any special configuration necessary to let this happen?

• Why is my global security group being filtered out of my logon token?

  - by Jay Michaud

  While investigating the effects of filtered tokens on my file permissions, I noticed that one of my global security groups is being filtered in addition to the regular system-defined filtered groups. My Active Directory environment is a single-domain forest on the Windows Server 2003 functional level. I'll call the domain "mydomain.example.com". I am logged onto a Windows Server 2008 Enterprise Edition machine (not a domain controller) as a member of the "MYDOMAIN\Domain Admins" group and the "MYDOMAIN\MySecurityGroup" global security group (among others). When I run "whoami /groups" from an elevated command prompt, I see the full list of groups to which my account belongs as expected. When I run "whoami /groups" from a regular, non-elevated command prompt, I see the same list of groups, but the following groups are described as "Group used for deny only". BUILTIN\Administrators MYDOMAIN\Schema Admins MYDOMAIN\Offer Remote Assistance Helpers MYDOMAIN\MySecurityGroup Numbers 1 through 3 above are expected based on Microsoft documentation; number 4 is not. The "MYDOMAIN\MySecurityGroup" global security group is a group that I created. It contains three non-built-in global security groups, and these security groups contain only non-built-in user accounts. (That is, I created all of the accounts and groups that are members of the "MYDOMAIN\MySecurityGroup" global security group.) There are other, similar groups of which my account is a member that are not being filtered out of my logon token, and this group is not granted any specific user rights in the security settings of this computer or in Group Policy. What would cause this one group to be filtered out of my logon token?

• "Tail" a logstash server query

  - by phatmanace

  Assuming I have a logstash server chocked full of logs being loaded regularly, is there a reasonably elegant way that I can tail the results of a continuously executing query on the logstash server and show this in a terminal window e.g some-special-logstash-command.sh | egrep -v "(searchword1|searchword2)" the idea being that the command pipes stuff out of logstash and to my grep query that filters and shows me the filtered output for. .. of course if there is a logstash command that can do the grep piece for me as well, then that works too :) motivation for doing this, is that assuming all of my events from my estate is being loaded into logstash, then would be nice to have a terminal window with a continuous tail of interesting events as they occur scrolling past the screen. -Ace

• scp using a password on the command line

  - by spierepf

  I am trying to write a script that will deploy a build created on my desktop machine (windows/cygwin) to a machine in my test environment (linux). I would like to use scp to copy the build to the target machine. The only account on the target machine is root, and I cannot create a special user for this task. The root user is unable to log in using an ssh key (I suspect that this is configured on the ssh server, but I do not know which configuration options control this). At any rate, I cannot change the configuration of the ssh server. My desktop machine uses Cygwin, and I have ssh installed. What I need is the command-line-fu that will allow me to put the password on the command line. I am aware of the dangers of having a plaintext password in a shell script, but that is not a concern here.

• How to rename multiple files by replacing word in file name geting from the shell script variables?

  - by fy6877

  This question like this thread. How to rename multiple files by replacing word in file name? My example is more complex than the above topic. The two variables are $name and $ newname getting from the shell script other location. $name and $ newname may have the unicode words or special symbles like []<?...etc,so could anyone help me to provide a method to add a part of script in shell scrit to solve file name replacing question. BTW,I try to type two kind of commands to change the part of file name, but it can't work. rename.ul '$name' '$newname' /home/fy6877/test/final/* ls /home/fy6877/test/final/|xargs -I$ rename.ul '$name' '$newname' $

• Some $_SERVER parameters missing when accessing PHP script via Cron

  - by Jakobud

  I have a script that I need to run with PHP via cron. The original author of the script made a lot of user of certain $_SERVER parameters (like REQUEST_URI). But it appears that certain variables don't exist when running PHP via command line or via CRON. For example, there is no request uri, so it makes sense that the REQUEST_URI parameter wouldn't be available. Is there any way around this other than to completely rewrite the script in order to avoid using special $_SERVER parameters that aren't universally available?

• How to link to an Excel pivot table that will expand over time in Word 2007?

  - by Daljit Dhadwal

  I have a pivot table in Excel 2007 which I’ve pasted it into Word 2007 using Paste Special (Paste link) - Microsoft Office Excel Worksheet Object. The pivot table appears in Word and the link to Excel is working. The problem is that if the pivot table expands (for example, due to showing 12 months of data rather than six months) the link to the pivot table in Word will only show the range cells that were originally copied over with the pivot table. I understand why this happens. When I paste as a link to Word the underling field codes look like this: {LINK Excel.Sheet.8 "C:\Users\myAccount\Documents\testexcel.xlsx" "Sheet2!R1C1:R8C2" \a \p} The codes refer to a fixed area (e.g., Sheet2!R1C1:R8C2 ) of the Excel spreadsheet, and so when the pivot table expands, the expanded cells fall outside the area that is defined in the field codes. Is there some way to have the link refer to the pivot table itself rather than the cell range that happened to be originally copied over from Excel?

• Prioritize file sharing performance in Windows Server 2008

  - by cmbrnt

  I've got a server running Windows Server 2008, and use it mainly for sharing files throughout the domain from a number of disks. It's running on VMware ESXi 4.0, in case that matters. My problem is that when I log in to the server to check user permissions etc, the access speed the files on the remote disks almost grinds to a halt. I havn't been able to measure the speeds, but I would guess it slows down to about 100kB/s as soon as I log in. This is on a gigabit network and the problems are equal for all users, even the ones connected to the same switch as the server. I've assigned 2 GB RAM to the server, and reserved it 1,5Ghz processor power. I don't have to do anything special on the server for this halt to occur. How can I make sure file sharing is prioritized on the server, so no matter what applications I'm using it will always make sure file sharing works properly? Could this be a VMware issue?

• How to manage SOAP requests to a pool of VM each listening on a HTTP port with a priority value in these requests?

  - by sputnick

  I have a front SOAP web-server under Linux. It will have to communicate with Windows Servers VM listening each on a HTTP port, for a HTTP POST request. The chosen VM should return a report of the task to the SOAP client. In the SOAP requests, there's a special variable : the priority of the request (kind of SLA), and my question is coming right now : I think of using a ha software (nginx, HAProxy, HeartBeat...) that can manage priority in this point of view. Is it relevant or do you think I need to implement a queue by myself with some specific developments? Ex: I have a SOAP requests with low priority in the pipe : the weight priority for these VM should be decreased if I have high priority SOAP requests at the same time. Any clue will be really appreciated.

• Bad password when logging in via Remote Desktop

  - by Shiraz Bhaiji

  I have just setup a windows 2003 server running in hyper-V. When I log in via Hyper-V it works fine. When I try to login via remote desktop I get a bad user name or password error. I have: Disabled the firewall Enabled remote connections Before I did the above I did not get to the login screen. I can ping the ip address of the image. I am trying to login as Administrator. Anyone have an idea about how to fix this? Edit I have now managed to fix this by changing the password to something without special characters. Strange thing is the I could not see any problems with the passord, had tried typing it into the user name field to check it.

• Turn off write barriers on ext4 whiche FS is mounted

  - by user462982

  I am doing some IO intensive DB imports that run for several days now and the IO performance has dropped tremendously over times. The DB data files (log files) are on an ext4 formatted logical volume which is mounted with default options (did not specify something special in fstab). Since I just learned that ext4 enables write barriers by default: Q: Is there some way to disable write barriers online (i.e. while the file system is in use), because I cannot interrupt the import and don't want to restart it again. I am aware that write barriers might not be the only thing impeding performance it is a bad idea to have write barriers disabled on journalling file systems if data safty is important (e.g. on a production system)
