• Dovecot ignoring maximum number of IMAP connections

  - by Michelle

  I have a single mailbox mail server running Dovecot/Postfix and I have two IMAP clients, Thunderbird on the PC and K9 on Android. I keep on receiving this error in my logs even after I change the 'mail_max_userip_connections' variable to 50. puppet dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10): user=<[email protected]>, method=PLAIN, rip=62.242.90.2, lip=198.29.31.229, TLS Why does it say that it is set to 10 in the log? Is that hardcoded? grep -r "mail_max_userip_connections" /etc/dovecot /etc/dovecot/conf.d/20-managesieve.conf: #mail_max_userip_connections = 10 /etc/dovecot/conf.d/20-pop3.conf: #mail_max_userip_connections = 3 /etc/dovecot/conf.d/20-imap.conf: mail_max_userip_connections = 50 I've restarted dovecot after making the changes but this error is still logged and I can't access the mailbox. Can anyone help me understand why I can't seem to raise the maximum limit?

• Windows Despooler Requires Administrator to Print

  - by Software Monkey

  Does anyone know what changes I might need to make to allow restricted users to print using a printer configured for spooling? My Windows XP SP3 system currently requires me to use an Admin account for printing if the print is configured to spool documents before printing. If the printer is configured for direct printing it works for all accounts. This used to work and some months back it just stopped, and I can't pin down why. The printer itself is configured for all uses to have complete authority. My system is locked down for restricted users given them only read authority to the entire file system except their data directories, which is how I have run my systems for years. I assume there may be a directory somewhere that I need to allow users to write to.

• Where is the Plesk Error Log / Or how can I get Plesk running again?

  - by Josh Pennington

  I currently have a VPS that is running Plesk and for some unknown reason it will not start. All the more information it gives me about it not starting is the following: Operation start with the VPS(s) VEID54635644 service "psa" is finished with errors: #703 Can not start/stop/restart service: service "psa" status is not "running" after command "start". This does really mean anything to me. Currently my server provider does not seem interested in helping me get Plesk running again so I am hoping I can get this going again on my own. I am assuming that there has to be an error log SOMEWHERE for Plesk, but the only thing I can find is located at /usr/local/psa/admin/logs/httpds_access_log and that just looks like an access log, not an error log (it is the only file in the directory). Is there another log somewhere in the system for this that I do not know about? Is there a way to find out why Plesk did not start? Thanks Josh Pennington

• How to set up Windows server 2008 to receive email?

  - by Saul

  First off apologies, I'm from a medical background not a networking one, but I've got roped into setting up a windows 2008 server. So far web server running, fixed IP address assigned (within a large private network of the National Health Service in the UK if that makes any difference) and the network team have assigned a DNS entry for me which works, so the server can be addressed as nww.myserver.nhs.uk I've only got ports open on the router for 80 and 443 (http and https) at the moment, so presume I need a different port to enable email services. My need is to be able to accept an email to the domain name like [email protected] in order to pick up a confirmation mail from an SSL issuer (Comodo) I guess to confirm that I control the domain. After that I don't actually need mail services on the server. I see lots of stuff about setting up SMTP services but thought that was about mail out and re-routing, but how do you get the server to "listen" for mail to the domain (assuming I open port xyz or whatever it is) ?

• Custom firmware for Asus WL-520g

  - by Jaroslav Záruba

  What custom firmware works with Asus WL-520g? (Note this is not 520gU, 520gC, etc.) I failed to flash it with Tomato (Tomato_1_28_ND.zip) - the admin UI does not accept the file, and when trying to tftp the file as adviced for 520gU all I get is this: Transfering file tomato-ND.trx to server in octet mode... Error occurred during the file transfer (Error code = 0): Error in SendPacket() call. I just saved the router form rather unsuccessful flash to DD-WRT (after few hours the router fell into coma), and I'd like to keep it as a backup should the new one die or whatever. (Unfortunately the stock firmware does not support WOL.)

• Urgent SSH Local Port Redirection

  - by Salina Odelva

  Hi, everyone. I have a shell account but the admin has restricted ssh access to the server. The server is listening on 0.0.0.0:22 but the firewall blocks any incoming attempts to this port. He says he is doing maintenance but I don't believe him and I need to backup my stuff with ssh. My question is that: Is it possible to do this: Me (Wan IP) <- Hosting Server (tcp/8080) redirects to Hosting Server (tcp/22) I don't want to involve my own linux machine in this and I can only make use of ssh.. Thanks!!

• administraitor denies command prompt

  - by roxas383

  I looked at the command prompt faqs on this webiste and tried to get me to make a new profile but when i went to open it it said "The command prompt has been disabled by your administraitor-click any key to countinue" and when i do it closes which i knew that was going to happen. Is there someway i can stop the admin from blocking my command prompt? oh and i was at school too (Dont know if this helps but i am in the West Allis West Milwaukee school district). Also, is there a way i can hack into the blocking program for my school at all? I don't remember what the program is but it might have to do with vision? I'm not sure but it would be greatly appreciated if someone could help (could i download a program on a flash drive that denies any blocking and/or disabling SafeSearch and plug it in into a computer at my school and use it from the flash drive? Would the school blocking thingy deny it from working?) HELP ME PLEASE!!!!!!!!!

• Cannont add service account to domain group during sql cluster install

  - by Sam

  I'm installing a 2008 instance on a 2003 machine which is already running 2005. I need to set up domain groups for the security setup step: http://msdn.microsoft.com/en-us/library/ms179530.aspx On Windows Server 2003, specify domain groups for SQL Server services. All resource permissions are controlled by domain-level groups that include SQL Server service accounts as group members. Much more info on this here: http://support.microsoft.com/kb/910708 I've had problems with being able to add the windows service accounts to the groups at install time. The security admins had to make my account a domain admin - which they were hesitant to do. The account under which SQL Server Setup is running must have permissions to add accounts to the domain groups. Is there a specific security setting which would allow my account to add accounts to a group?

• How to get a service to listen on port 80 on Windows Server 2003

  - by Miky D

  I've coded a custom windows service that listens on TCP port 80 but when I try to install it on a Windows Server 2003 machine it fails to start because some other service is already listening on that port. So far I've disabled the IIS Admin service and the HTTP SSL service but no luck. When I run netstat -a -n -o | findstr 0.0:80 it gives me the process id 4 as the culprit, but when I look at the running processes that process id points to the "System" process. What can I do to get the System process to stop listening on port 80 and get my service to listen instead? P.S. I should point out that the service runs fine if I install it on my Windows XP or Windows 7 development boxes. Also, I should specify that this has nothing to do with it being a service. I've tried starting a regular application that attempts to bind to port 80 on the Windows Server 2003 with the same outcome - it fails because another application is already bound to that port.

• Creating svn repo programmatically from a webpage and sudo

  - by Adriano Varoli Piazza

  We want to automate the creation of the svn repos and trac environments for new projects. Basically, this would mean creating a web script that got some info (like env and repo name, etc) from the user and then executed sudo -u svn svnadmin create /var/svn/<projectname> trac-admin /var/trac/sites/<projectname> initenv [... All extra params...] For the second command, this is simple, as it already runs as the www-data user, so I wouldn't have to use sudo. But for the first command, I'd have to use sudo and add www-data to the sudoers file. I was wondering if this is a good idea, and how to do it in that case. Reading the manpage has left me with more doubts than certainties about this. This webserver would only be accessible from our internal network, by the way. The OS is Ubuntu Server 10.04.

• Proxmox - Uploading disk image

  - by davids

  I've got a KVM Virtual Machine in my local PC, and I'd like to copy it to a Proxmox server. According to the docs, I just have to create a new VM on Proxmox and add the existing disk image to it, but how do I upload the image to the server? In the admin panel, if I click in MyStorage - Content - Upload, it just give me options to upload ISOs, VZDump backup files or OpenVZ templates. Would it be enough with a copy using scp? In that case, in which folder?

• vhost.conf with plesk makes infinite loop

  - by user134598

  So I'm trying to make rewrite rules for my just migrated site and now we're using PLESK (unfortunately in my opinion). So, in order to make those rewrites I'm using the vhost.conf file in mydomain/conf folderm and I execute: /usr/local/psa/admin/sbin/websrvmng -u --vhost-name=mydomain.org so that includes my file into the httpd configuration. However, no matter what I write in my vhost.conf file, it will make my site go in an infinite loop whenever I try to load an URL that's not just the domain. Example: mydomain.org Works just fine. mydomain.org/event/nameofevent Will try endlessly to load and eventually my browser will detect that infinite loop. I though I was writing something incorrectly in my vhost.conf file but I even tried it with the file empty (not a single line). It will still try to load endlessly. Anybody can hint me if I'm skipping a step before (like any activation that should be done beorehand or something). Thanks in advance.

• How to calculate time spent for Linux system administration?

  - by Jaakko

  I would love figuring out how much time I actually have spent in shell performing administrative duties. For billing of course, this information is not sufficient, but it would be helpful to figure out how much time I have actually spent in shell. My question is: How anyone got tips on how to calculate time spent in shell (in hours + minutes), let's say per user account? Could anyone recommend a software that could be used to analyze this time? Optionally I would like to know about ways how to categorise time spent (e.g. 1 hour for Apache, 2 hours for Samba, etc.) Also, your takes on how you monitor your admin time, are also much appreciated! To narrow down the problem, I am specifically interested in ways of tracking time spent in shell for Linux system administration

• rpd over https using a linux client

  - by Nils

  My employer switched from vpn and rdp to using what our admin calls "rdp over https". Since that switch I find myself unable to connect to the "new" rdp server. I think the progress is as follows: A rdp gateway-server is connected via tls the requested sever (different from the gateway-server) is then connected through the tls connection. In windows mstsc-settings the server name is the "internal network name" of the machine I wish to connect. And on the last tab (in German it is called "leistung" - could be activity) I go to the "connection from everywhere" settings and set the gateway-server under gateway-server. Now: Is there any way to use this scenario under linux (apart from a virtual machine running Windows)? I am interested in free ideas (e.g. is it possible to create a tls tunnel and connect through that using freerdp/rdesktop?) non-free ideas. As long as they work I'll worry about the costs later. Free ideas would be better :-)

• Xinetd , vncserver memory requirement

  - by JP19

  Hi, I am installing the following on a low memory system: vnc4server xinetd xterm openbox obconf I will only occasionally be logging into the vncs for some admin work. My question is: 1) Does xinetd take memory / cpu even when vncserver is not running? If so, can I "run" xinetd on demand (how)? And if no, any idea how much memory it will take when vncserver is not running? 2) Does vncserver take substantial memory when no clients are connected? 3) Do openbox/obconf take memory when vncserver is running but no client are connected? 4) Do openbox/obconf take memory when no vncserver is running? thanks JP

• Should a sysadmin contractor charge overtime for off-peak hours?

  - by Jakobud

  This is not necessarily a server-related question, but more of a system admin question that I think would related to many on SF. I'm doing Sysadmin/IT consulting for a small company. I only work about 3 days a week for them on average. If a server goes down or something like that during off hours (nights, weekends, 3am, etc) and they need it fixed during those time periods, should I be charging overtime for that? I would I not be justified in charging overtime until I've logged 40 hours for the week? Perhaps calling it overtime isn't the best name. I guess maybe its better to call it an off-peak hourly rate. Anyways I just was curious what other consultants did in these circumstances.

• Exchange can't send emails with attachments

  - by Jack

  No one in our organization can send emails with attachments. Emails without attachments go through fine, but if an attachment is included, an error appears in the Server Failures folder under Sync Issues. The error is "The following message had an error and synchronization of it was skipped (0xc0090081)". We are using Symantec Mail Security, which we shut down to try to troubleshoot the problem, and now that fails to load. Any ideas as to what to check? I'm sorry I don't have more complete information, but I'm helping someone try to figure this out. I'm not the admin myself. Thanks.

• Simple github fetch/merge not pulling in remote branch?

  - by chum of chance

  I have a project I forked on github to my repository. I made changes on the "experiment" branch of the project the committed the project to my fork. If you go to my branch on Github you can see the that the experiment branch was correctly committed. I would like to merge the experiment branch with the original repo (which I have rights to). I issued the following commands: git clone [email protected]:originalrepo/theproject.git git checkout -b experiment origin/experiment cd theproject git remote add experiment [email protected]:chumofchance/theproject.git git fetch experiment git merge experiment "Already up to date" However, when I view the project in explorer, it appears that nothing has changed. Am I screwing something up in regards to fetching the experiment branch (vs the master branch)?

I seem to be able set up my "admin-user" in pidgin no problem but when I try to register a new user I get a 403 Fobidden message back from pidgin. Do I need to change the ejabberd.cfg file to allow users to register? If so how do I go about it? If not what do I need to get basic chat and fileshare going?

• Subversion terminology. Difference between projects, modules and root directories

  - by aioobe

  I'm setting up a repository for me and some colleagues. I have a subversion repository at hand, and all required rights. The usual directory-skeleton has been set up for me (branches, tags and trunk). Now I'm about to create a directory for me and my colleagues to put our files in. I'm quite sure the right place to put it is in trunk. Now here and there in tutorials, I see terms like "modules" and "projects" such as in Checking Out a Project - svn checkout svn checkout http://host_name/svn_dir/repository_name/project/trunk proj Is proj in the above line some glorified directory in trunk? Should I do something else than a checkout on trunk, mkdir and then commit when creating a directory for me and my colleagues? Whats the difference between a project, a directory in trunk and a module?

• Multi users windows login?

  - by DennyHalim.com

  I need a way to login multiple users into windows at startup, in (XP/Vista/7) I need for each time windows starts, all registered users will automatically login and starts all apps in their startup folder under their own credentials. Any ideas how I could achieve this? i need a 'cheap' alternative to windows vps. lots of people need vps to run certain apps and leave it running. it's less likely they need full admin access other than installing those apps. instead of each users have their own vps running simple apps, it might be cheaper to have one multi-user server to accomplish this?

• Active Directory theme policies

  - by Tuinslak

  Hey, I'm currently managing a terminal server in a domain. As the TS-service just got installed, previous users (I logged in with every user once to test it and set up a few things) use the default windows 2008 theme. New users automatically use the fancy Aero theme. Is there a way to push the Aero theme to all current users? I currently have something like this in my policies: However, when logging in with a user, the theme is not changed. Only if I disable "prohibit access to the control panel", the theme can be changed (doesn't seem to change automatically). But this gives them access to every other control panel feature as well. And giving users only access to "desk.cpl" CP-applet, gives them an access error as well when attempting to change the theme. Another question: can I, as admin, take over and/or log in as another user when that user is not logged in? Thanks

• Having trouble getting startup scripts to work in Server 2003

  - by Az

  Thanks for taking the time to read this. I am having trouble getting my startup scripts to run correctly on the domain I am administering. Before anyone gets upset and says "go read xxx article from microsoft",... I have. I am simply missing something or not understanding it properly. I understand how to assign the script, what I am curious about is where exactly it should be placed in the Windows folder structure. I have been able to get them to work by creating a share folder called "scripts" and pointing to that exact unc pathname IE \servername\scripts\xxx.bat. However, I would like to do it properly, would someone please tell me where they should be placed in Win2003 server, and what the path name should be when assigning a group policy to do something that applies to computer specific properties? Your assistance is very much appreciated by a junior admin trying to learn some new tricks!
