• Default permissions for courier imap folders

  - by JoeCoder

  I'm using courier imap. When a mail client creates a new folder, it's created on the filesystem with 640 permission. I need it to be writable by the group, or 660. I currently have /etc/courier/imapd IMAP_UMASK=007, but that's not enough. I'm not sure what else to try. Any ideas? I'm using ubuntu server 12.04. EDIT: I added a 50pt bounty to this. For an acceptable answer, I need a way to make it work from a package in a standard repo. If I download source and compile it myself, it won't be automatically kept up to date with security fixes. If I don't find a better answer, I'll add code to the admin script to call another sudo approved script to chmod -R the whole directory before every change. But this is kind of hack-ish.

• Configuring Fortigate OS4 for FTPS

  - by Paul

  I configured iis7 ftp to allow ssl connections. I set the ssl firewall to use ports 50000-50050. If I set up a custom service on my fortigate firewall for ftps with source ports 990-50050 and destination ports 990-50050, set it to a firewall policy and connect from a client it connects and works successfully. If I create a service FTPS Control with source port 990 and destination port 990 and another service,FTP Data with source ports 50000-50050 and destination ports 50000-50050 add them to a group FTPSSL, replace the ftps policy with FTPSSL and try connecting it tries to connect to port 990 and eventually times out. Is there a way to configure the service to only use the ports I need and not every port from 990 up?

• What's an easy way to install a bunch of OSS apps in my home dir on my company's aging Redhat VNC servers?

  - by subopt

  My company's IT group doesn't want to install lots of common stuff on our VNC servers, which run RHEL 4. The list of stuff i want/need includes graphviz, midnight commander, various python libs, sqlite, netbeans, antlr, jdk1.6, etc. They've hobbled rpm somehow, so i can't do rpm --relocate. And i don't want the RHEL4 compatible revs of this stuff anyway. I've probably got the room to build all this stuff in my home dir, but i don't want to take forever tracking down dependencies. Looking for an easy way to get the apps/tools i need, and nothing (or very little) else. Any suggestions?

• Looking for the best ec2 setup for 3 sites totaling in 1.5 mil in traffic monthly

  - by john h.

  I am looking to consolidate our current aws setup of 2 Large ubuntu ec2 servers and 2 large RDS server for our 3 websites that have a total of about 1.5 million hits a month and increasing every month with the majority of traffic (1 mil) to one forum site in the group and the rest of traffic to an ecommerce site and a small wordpress site. So here is my question/thought? Would it be better for us to combine the two ec2 large servers to just one and same with the 2 RDS servers so we run all three sites off one large ec2 and one RDS. -or- Should we setup maybe 2-3 smaller ec2 servers load balenced and a single RDS. -or- Something completely different setup? One concern is that if one site crashes it takes with it the others. It happened in the past but I am pretty sure its because of the forum software and not the server setup. -john

• Secure PHP environments with PHP-FPM and SFTP

  - by pdd

  I'd like to set up secure environments for a small number of untrusted PHP websites on a Debian server. Right now everything runs on the same Apache2 with mod_php5 and vsftpd for administrative file access, so there is room for improvement. The idea is to use nginx instead of apache, SFTP through OpenSSH instead of vsftpd and chrooted (in sshd_config), individual users for each website with their own pool of PHP processes. All these users and nginx are part of the same group. Now in theory I can set 700 permissions on all PHP scripts and 750 on static files that nginx has to serve up. Theoretically, if a website is compromised all the other users' data is safe, right? Are there better solutions that require less setup time and memory per website? Cheers

• Losing WLAN connections but maintaining internet connections on WIndows 7 Workgroup

  - by Di

  I have 4 computers all running Windows 7 networked in a Work group through Billion 7404vgp-m wireless router.All drivers and firmware for wireless adapters and router are up to date. Windows Firewall and Defender disabled.Disconnected ipv6. Running Nod 32 anti virus software. All have own static IP address 192.XXX.X.XXX. When I Reset the router all computers have Internet and LAN access for about 1 hour and then they will lose the LAN connection but maintain Internet connection. Resetting wireless adapters or restarting computers does nothing to fix this but resetting router will. What is causing this and how do I fix it. Thanks Di

• osx 10.6.3 how does apache config work?

  - by w-

  hi, just got a macbook pro 15" so i'm unfamiliar with how the filesystem is laid out. i noticed when in my filesystem that i've got a few paths specifying httpd.conf /etc/apache2/httpd.conf /opt/local/apache2/conf/httpd.conf /private/etc/apache2/httpd.conf the confs are different in lots of ways-- e.g. user, group, server_root, modules that are loaded, etc. the apache2 folders themselves also greatly differ. it seems that the one getting used is either /etc/apache2/httpd.conf or /private/etc/apache2/httpd.conf i'm wondering if i might have messed up my system after installing some packages (php5, django, etc) via macports and maybe ended up with 2 apache2 instances. my questions are hence: - which httpd.conf is the one being used ? - what are the other files for? thanks

• Can't uninstall SBS 2003 in sbs 2003 -> sbs 2008 migration

  - by ChrisMuench

  I'm trying to remove sbs from my sbs 2003 server. Also I'm logged in as Administrator. However When I start to go through the wizard it gives me the following error. You must be a member of the Domain Admins, Schema Admins, and Enterprise Admins group. I then did some research and found this (http://support.microsoft.com/kb/842694) and I came to the point where it says to delete the server from Sites and Services. However when I clicked delete it wanted me to dcpromo the box first. However I have read you have to uninstall exchange first and then dcpromo it to remove AD. Any ideas?

• Receiving "May not have permission to edit" warning, even though I have permissions

  - by Choy

  I'm using Panic Transmit as an FTP client connecting to an Ubuntu 12.x server. When I try to edit and upload a file using it, I receive the warning that tells me to check my permissions as I may not have permissions to edit a file. I'm not setting the permissions on upload and I do have permission to edit files. After clearing the warning and checking the file on the server, may changes go through. The files I'm trying to edit are set to 775 and are part of the www-data group which my user is part of as well. Any idea why I would be getting such a prompt? This only happens on some files, not all.

• difference between compiled and installed via rpm (zypper)

  - by cherouvim

  In an openSUSE 11.1 I download, compile and install ImageMagick via: wget ftp://.../pub/graphics/ImageMagick/ImageMagick-6.7.7-0.zip unzip ImageMagick-6.7.7-0.zip cd ImageMagick-6.7.7-0 ./configure --prefix=/usr/local/ImageMagick make make install Everything works nicelly until I discover that JPG is not supported: identify -list format | grep -i jpg [nothing related to JPG returned] So I reconfigure and recompile using: ./configure --prefix=/usr/local/ImageMagick --with-jpeg=yes --with-jp2=yes make make install But that changes nothing. I end up uninstalling: make uninstall and installing via zypper: zypper install ImageMagick This installed version 6.4.3 and now it does support JPG: identify -list format | grep -i jpg JPG* JPEG rw- Joint Photographic Experts Group JFIF format Any idea on what is going on here? What is a possible reason that this capability of ImageMagick was not there when compiled from source but was there when installed from rpm? Note that I don't necessarily care a lot about ImageMagick (since it now works), but generally about his kind of behaviour, becase in one way or another I've seen this happen in other ocasions as well.

• Is there an effective tab manager for Google Chrome?

  - by Mahn

  I've tried a few extensions but I wasn't very satisfied, I'm basically looking for an extension that allows me to group sets of tabs in such a way that I'm able to quickly switch between the groups within the same window. That is to say, if I had 5 Wikipedia tabs and 5 Stack Exchange tabs, ideally I would create 2 groups, hide the tabs of one of them, and switch between the Wikipedia and Stack Exchange tabs back and forth as I need without leaving the same window (note that I'm not specifically looking for grouping by site, that was just a simplified example) Does an extension like this exist? PS: No, I don't actually have 5 Wikipedia tabs open while browsing Stack Exchange sites :-)

• What could prevent one Amazon EC2 instance from pinging another instance's Private IP?

  - by ks78

  I have multiple Amazon EC2 instances which need to communicate using private IPs. However, so far I've been unable to ping one instance's private IP from another instance. I can ping external addresses, such as their Elastic IPs and other sites (yahoo, google, etc), so it seems there's nothing wrong with the instances' network configuration. Also, they are all in the same zone, so that shouldn't be an issue. Does anyone have any idea what I could be doing wrong? Could this related to the Security Group settings?

• NGINX + PHP FPM connect() failed (110: Connection timed out) while connecting to upstream

  - by Leonard Teo

  We're running a fairly large site using nginx and PHP-FPM and we're getting a lot of errors as the site load is quite high. We're getting "connect() failed (110: Connection timed out) while connecting to upstream"...upstream: "fastcgi://127.0.0.1:9000" Here's my config file for PHP-FPM.

• Is there a registry key change that will by-pass the Windows Domain Join Welcome page?

  - by user1256194

  I'm scripting some Windows Server 2008 R2 builds using Power Shell. Some software needs to be installed after the server has joined the domain. Since I want to automate everything, I'm looking to by-pass the domain controllers Welcome page using a registry hack script. I work for a large company and the Active Directory people are unwilling to change group policy. I figure if it's a registry key I can script the change, install the software, replace the key and reboot as the final step. Is there a registry key change that will by-pass the Domain Join Welcome page?

• Mapi session exceeds maximum count of type objtMessage

  - by wullxz

  one client (it's allways the same client) has often problems with mapi sessions killed by the exchange server. The Application Eventlog on the exchange logs eventid 9646 with source MSExchangeIS: Die MAPI-Sitzung '/o=xx/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=xxxx' hat die maximal zulässige Anzahl von 250 Objekten vom Typ 'objtMessage' überschritten. The client has no eventlogs logged about this error. I looked for installed Outlook Add-Ins and found the default add-ins from microsoft, an adobe pdf add-in (which I deactivated because it's not needed) and an "Octopus" plugin from telekom. Octopus is a CTI-application that connects to Outlook. My guess is, that Octopus (or its add-in) causes this error because this client has over 1100 contacts. My question is: how can I find out, which application/add-in causes this problem? Edit: I already looked at eventid.net but nothing helped. Edit2: Exchange-Cache-Mode is not used nor are there any shared folders / mailboxes open.

• Setting user calendar permissions on Exchange 2007

  - by blizz

  We have Exchange 2007 with about 100 users. I would like to change everyone's free/busy permissions to grant Reviewer status to a specific AD group. I have tried PFDAVAdmin tool but when I commit any changes, they do not affect the users. If I grant myself Reviewer permissions to another user's calendar using the tool, I still cannot view that user's free/busy details, and I also don't show up on the list of people with permissions on that user's Outlook calendar options. It seems like PFDAVAdmin simply appears to do something, but doesn't actually change anything. Is there any other way for me to accomplish what I need to do? Or is there something I may not be doing right with PFDAVAdmin? FYI I have followed directions from this link: http://exchangeshare.wordpress.com/2008/05/27/faq-give-calendar-read-permission-on-all-mailboxes-pfdavadmin/

• Remote Desktop session on Windows Server 2003

  - by Dels

  I have some problem when I use Remote Desktop, here some description. I set some application to autorun each time Administrator (console) was login on W2K3 SP2 server I use Remote Desktop from XP SP3, using the same login as Administrator It creates a new session with the same username and the application starts autorun which make duplicity in application I just hoping i can enforce the Remote Desktop client to connect into only one session (console session), toying with Group Policy setting, successfully enforce the one session, but whenever i close remote desktop (disconnect) the console got disconnected too (which I didn't want it to behave like that). I also try some setting to limit connection, still it doesn't behave as I want it too. Simple i just want to use 1 session, but each time we close remote desktop the session still alive, much like when we use VNC solution (RealVNC, UltraVNC, TinyVNC etc.) Any solution(s)?

• AWS RDS MySQL remote connection extremely slow

  - by nute

  I have a site hosted on AWS EC2 (Elastic Beanstalk), with a MySQL database hosted on AWS RDS. Everything works fine on the production server, fast and all. However when I try to connect remotely from my local machine, it sometimes gets extremely slow (like 4 minutes to load the list of tables), or simply times out. I added my IP in the security group (which I did correctly, since it sometimes works). When it doesn't work, I at the same time check the prod server and it still looks good.

• Cross domain LDAP

  - by Adam

  For a system we are developing we have 2 domains an internal and an external domain with bi directional trust between them. However the servers are only able to connect to their own DC's. We have an application server on the internal domain which needs to use an LDAP query to gather a list of users from a group on the external domain. How do i go about writing an LDAP query that asks one DC to go ask another DC for a list of users. I tried querying the internal DC with the same LDAP query I would use if it could hit the external DC directly but this does not work. When i use Softerra LDAP Administraor I can view the full hierarchy of the interal domain but despite the trust relationship between domains i am unable to see any of the external doamin. Any suggestions or help would be greatly appreciated

• RHEL 5/CentOS 5 - sshd becomes unresponsive

  - by ewwhite

  I have a number of CentOS 5.x and RHEL 5.x systems whose SSH daemons become unresponsive, preventing remote logins. The typical error from the connecting side is: $ ssh db1 db1 : ssh_exchange_identification: Connection closed by remote host Examining /var/log/messages after a forced reboot shows the following leading up to the restart: Dec 10 10:45:51 db1 sshd[14593]: fatal: Privilege separation user sshd does not exist Dec 10 10:46:02 db1 sshd[14595]: fatal: Privilege separation user sshd does not exist Dec 10 10:46:54 db1 sshd[14711]: fatal: Privilege separation user sshd does not exist Dec 10 10:47:38 db1 sshd[14730]: fatal: Privilege separation user sshd does not exist These systems use LDAP authentication and the nsswitch.conf file is configured to look at local "files" first.

• CentOS, sudo Doesn't Accept root Password, but Logging in as root Works

  - by nicorellius

  I am new to Linux and I have CentOS running on a dual boot system. I was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?

• How to manage configuration & automatic rollout of 20 virtual machines

  - by Lucas Meijer

  I have a TeamCity build server, with about 20 "build agents", both Windows and MacOS machines. Often, I need to install a newer version of XCode or VisualStudio or some other tool. Having to do this on all machines manually is boring and error prone. I'm trying to find out what is the best way to achieve the following: make it easy to change a system configuration, without having to do it on all machines manually. make it easy to add a new machine to the group. ensure the machines are as identical as possible The jobs these machines are executing is relatively heavy, fully consuming 8 cores, and be very heavy on IO. It's fine if the solution includes spending money.
