I work for a college with many departments. I'd like to just deploy one LDAP/krb5 server (plus slave replicas) to authenticate all users in all departmentsIs it possible to do this?The proposed DNs for the departments matches what is done for NIS now.If anyone has any pointers or URLs that describe how to properly do this.

View 2 Replies View RelatedTwo exchange servers internally. One is setup for example.com (192.168.1.10) and the other is setup for example2.com (192.168.1.20) Both are behind a single public IP.
I want to use postfix to sit in front of the two exchange servers. Postfix will accept mail for both domains and relay to the appropriate server. I have postfix installed with only defaults at this point.
I would like to set up an ubuntu server to forward outside requests directed to different domains to different computers on my local network. The bind is I only have ONE public IP.
Here's an example of what I want to do.
- if a request is sent to www.first-domain.com, I want to forward it to a local server (say 192.168.0.10)
- if a request is sent to www.second-domain.com, I want to forward it to a local server (say 192.168.0.20)
and so on...
I will need to forward these requests not only for web sites but for other services such as SSH, mail, RDP, VNC, etc etc PS Once it hits those local servers, I know how to use iptables to forward them as desired.
how can i configure my server to send mails from about ten different domains i use google apps and want to know if its possible. Because it sends mail but all goes to spam and i have a static ip
View 9 Replies View RelatedI have a domain.com site up and running on my server. I just bought domain.net, domain.org and I would like it to point to the same site on domain.com. I am not sure how to go about doing this.I used zoneedit for my dns. So far I have pointed my 2 new domains to the same dns as my .com on zoneedit and I have created (A) ip address for them. If I did this correctly, the new domains are pointing to my server and all is left is to edit the virtualhost?

View 7 Replies View RelatedI have Postfix + Unix Accounts + Virtual Domains. I have a bunch of domains hosted on my machine, let's call them [URL] [URL] and [URL]... etc Until know, domain2.com, domain3.com were mapped in virtual domains to [URL] So this is how /etc/postfix/virtual looks like:
[URL]
Like I said, all mail accounts are unix accounts, so, if for example I have the user "paul" this user will receive e-mail for ALL DOMAINS. [URL]But as it turns out, I now need a COMPLETELY ISOLATED domain... let's call it [URL]. So If I create a new user, let's call it "steve" I want steve to receive e-mail ONLY on [URL] and not on all others.
I would have to redo the whole thing from the beginning. I'd have to comment out the $mydestination parameter in the main.cf file and start using only virtual domains. So if I have the following users: paul, steve, sally, megan, jenny and I want paul and steve to ONLY receive mail for domain1.com, sally and megan to receive mail for domain2.com and jenny to receive mail for domainX.com, my /etc/postfix/virtual file would have to look like this:
[URL]
I'd have to create the unix account and then start modifying the /etc/postfix/virtual file.
how to install webalizer and configure it to push stats for multiple domains?
View 6 Replies View RelatedI want to configure a single mail server to send and receive mail from multiple sub domains of my domain. I've already installed Postfix/Dovecot and it is perfectly working for mydomain.com. And also installed roundcube for Web Mail. Can I further customize this setup to process mail to sub domains? ex- someone@subdomain1.mydomain.com, someone@subdomain2.mydomain.com, someone2@subdomain1.mydomain.com (someone@subdomain1.mydomain.com and someone@subdomain2.mydomain.com are 2 separate users. they should be able to log on to web interface separately)
Currently i use system account names as email user names. (ex - systemusername@mydomain.com). The only MX record in my domain DNS pointed to current server (mailhost.mydomain.com). I read about postfix virtual domains. but couldnt figure out how to use it to achive my target. I do not need configuration details. Just explain me the way to do it. I can do the rest my self.
Is it possible to add/join my Linux Suse 11.3 server with 2 domains ? I know I can do that with Windows PC, but I never try that with my Linux box. FYI, my Linux server is already joined with a domain, now I want to join my box with another domain and I don't want to take it off the current joined domain.
View 1 Replies View RelatedI am setting up a Postfix MTA that will be only sending mail for 10 different domains. We have other servers that will be receiving the mail for the domains so I only need to set up for sending on Postfix.
What my issue is I am trying to configure Postfix so that when it sends mail the header shows what domain the mail came from and not the domain the Postfix server is set to. For example....
[URL]
When I send mail from domain2.com I want it to show in the header it was sent from domain2.com and not from domain1.com. What do I need to set in postfix so that this happens? Right now no matter what domain the mail is from the header always shows the server domain and I can't have that.
I am using squid 3.1.12 as a proxy cache. All the requests initially land on a Apache server which acts as a reverse proxy server, the Apache redirects some URLs based on the context to Squid server. This Squid server based on the URL needs to forward the request to the specific tomcat server where the application is deployed. I am able to configure just for one application but how do I configure multiple tomcat servers(each tomcat having different application deployed on it). Squid needs to redirect based on the URL.In Squid.conf I made the following changes
[URL]
cache_peer abc.dev2.xxx.com parent 8080 0 no-query originserver refresh_pattern -i /ABC144020%1440 override-expire override-lastmod reload-into-ims ignore-reload
#cache_peer def.dev2.xxx.com parent 8080 0 no-query originserver
[code]....
Here Squid is deployed on my host [URL], Apache redirects any URLS with the context 'ABC' or 'DEF' to squid. Squid needs to redirect it to the individual hosts thats [URL] or [URL] based on the URL. I have commented the entry for DEF in my squid.conf as it was not working. But it does work for any URLs with ABC as the context.
I have configured postfix to send/receive mail from/to for two domains we manage. [URL] and [URL] Most of the cases there is no issue sending out or receiving emails. However, a few users of domainY.com complained that their senders were not able to sent them email. after much investigation, we started thinking that the mailserver failed to send us email may the failing on doing a SMTP Banner issue.
Is there anyone who knows how to deal with this SMTP banner issue with multiple domain. We want different SMTP banner when doing EHLO on different server.

I'm running a server with two sites which both need to be able to send emails. Currently I have Postfix set up to send email via Google Apps. This works fine, but Google's servers ignore the From: address I specify and substitute the one I logged in with. Is there a way to make Postfix log into Google Apps with a different username based on what site the email is coming from? The server does not recieve any mail itself; Google recieves it and we have it set to forward it to the appropriate person's real email address. I'm only worried about sending mail.
(Postfix is not a requirement here, so if there's another mailer that can do this better, I'm open to ideas. However, sending email directly from the server isn't an option as it's a residential IP address and blocked by most of the big email providers.)
I am currently running a apache/postfix email service on my server. I am using aliases for two addresses for example:
trscookie@serverone.com
trscookie@secondserver.com
so the emails no matter which domain receives the email trscookie always will receive the email.
However I am unable to work out how to 'reverse' this process, for example.
If i was to go to secondserver.com/webmail I would like the emails to get sent from trscookie@secondserver.com however they are currently all coming from serverone.com. Is it possible to configure this so that it is sent from the correct domain?
Here is my main.cf:

I'm trying to pass multiple dpmains thru one ubuntu server to various hosts on my local network.
[url] should be sent to the /var/www folder on the local host.
[url] should be forwarded to an IIS box on my local network (owa.nunya.local)
[url] should be sent to another ubunto box on my local network (smtp.biznet.net)
I have tried placing VirtualHost entries in /etc/apache2/sites-available/default and [url]and [url] both work but [url] gets forwarded to the c:inetpub folder on the IIS box.
I've tried to set up an old laptop with Ubuntu server - need to use it as a web server for a group of students on a local network only. I managed to get it working fine for just one user publishing webpages etc to a folder called VAR/WWW I could FTP files into the folder and access them again via FTP or a browser. I then decided to create some subaccounts (one for each student) I did this by typnig the following commands:
Sudo usermod -g www-data student1
Sudo chown -R www-data:www-data /var/www/student1
Sudo chmod -R 775 /var/www/student1
(In this example student1 is intended to be a subfolder of www and act like a sub-domain with write authority- at least that was my intention) Problem I then get is that if I use Filezilla to access each account I cannot see where to publish the files - wherevever I place them they are not accessible from the browser. Do any of you experts out there know the answer to my problems please.
I'm in the process of starting a migration from an old postfix server to nice shiney new exim server however there are a few things i'm really not clear on and i'm hoping that some one here could point me in the correct direction. Okay the postfix server at the moment does the follwoing ( i'll try and keep this simple ):
* accepts incoming mail for users on multiple domains and puts the mail in the users mailbox ( external -> internal )
*accepts mail from users on multiple domains to pass on to the outside world ( internal -> external )
Obviously the POP and Imap functions are handled by other daemons.. I'd like to replicate this sort of setup on the new exim box, however the guides i can find only help with configuring the exim system for incoming mails ( external -> internal ) for multiple domains and i cant seem to find a guide that would indicate how to do both ( internal -> external and external -> internal ) on one box. I'm guessing i may have to do some sort of auth to get exim to accept and then handle the internal -> external side of things?
I'm trying to follow the OpenLDAP docs that are part of the Ubuntu 10.04 Server Guide, listed here:
I get about halfway through, to this command:
sudo ldapadd -x -D cn=admin,dc=example,dc=com -W -f frontend.example.com.ldif
When it asks me to "Enter LDAP Password:" and nothing I have tried works. I thought it might have been "olcRootPW: secret" set in the backend file in the step before, but that isn't working.
I am going to try and replace our crappy Windows/imail server with a new ubuntu 10.04 LTS based machine. It will end up with about 400 domains on it with around 3000 users total. 96% of the domains have very light use. 4% of the domains have heavy use but do not send any bulk mail.
Can someone here recommend a mail server software package that would be easy to administrate and easy to backup/replicate? All we need is POP with webmail. We do not need IMAP or want any group/collaborative functions.
What do you usually use for anti-spam on a linux mail server? We want to keep it all open source if possible.
For hardware we are looking at an HP DL360 G5 with dual Xeons, 4G of ram, and the P400 controller with 6 SAS 15k drives. Do you think a server like this will be able to handle the mail on linux? Volume is around 400k messages a day inbound with about 10% being legit/90% being spam. The server will be dedicated to mail hosting and will not host websites.
I am planning to deploy an OpenLDAP server in my LAN for basic authentication, but I have no idea how to do it. I would like to know how to configure an OpenLDAP Server, and I would also like to know about knowledge resources, if any.
View 3 Replies View RelatedI have several web servers running apache on my LAN. Each internal server hosts a number of domains.I would like to make these available to the internet and make sure they all get to use port 80 and 443.My idea was to put Apache on the firewall and have all http(s) traffic from the Internet to my firewall be redirected by Apache to the different internal apache servers. This, in theory, would allow me to keep the standard http(s) port.
Can this be done? I was thinking of mod_rewrite and mod_redirect but in all honesty, I'm a little at a loss on where to start.Can someone point me to relevant documentation or give me the basic idea on how to start?
I recently purchased a GoDaddy domain with the intent of hosting a website myself at home on a box First of all, I don't have a static IP, so I set up dyndns with my router. Do I want to just have GoDaddy forward traffic to my dyndns account? Or do I manually change the nameservers? To what? Also, this seems to work for http(s) traffic only. What happens if I want to use ssh/ftp/smtp? And do I need to configure anything on my end aside from installing/configuring the appropriate server binaries? Is there a way to update GoDaddy when my ip changes?

I am constantly getting the following error, no matter what I do:
I'm looking at setting up a couple automated systems: Here are a few examples:
* Internal accounting system to download and process emails
* Public web server to visit
I could put each system on its own separate box -- for example, it's generally good practice to separate anything that external users have access to (such as a webserver) from internal processes such as accounting. Now, rather than dishing out the money for two separate servers, could I get away with just installing new instances of VMWare on the same box for each system?
To give you an idea, these are not large scale computationally sensitive systems. The accounting one is simply downloading and tallying emails, and the latter is just a webserver with maybe 5 hits per day on a good day. I could definitely pick up a new box for say $50, but I wanted to know the general practice of using VMWare on the same box versus two separate boxes.
I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'
From: [url]
I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
I've sifted through hundreds of Google results, but I cannot seem to find a tutorial or how-to for installing and configuring Postfix on Red Hat Enterprise for use with multiple domains. We have a web server serving four websites so far. Each of these websites has their own domain that they'll require email for.
