I have installed the following successfully.

Now I wish to make my own mail server for my organisation we already have a ISP server but would like to act this for our local delivery and store mails something like what a daemon does. For this I did the following:
Installed fetchmail
Installed send mail
Installed exim
Installed squirell
And now I am completely lost. How do I setup from here. So that I can configure the server.
My server spec are:
PIV 2.8GHZ, 512MB ram, 80GB HDD, HIS MOtherboard, lan card. I don't have any DNS or other stuff here in our office.
I cannot receive mail from my POP server; I used the same settings as I previously did with Thunderbird but I keep recieving an error message "La lecture de salutations valides du serveur POP pop.videotron.ca a �chou�" (roughly: exchange with the POP server failed).I am able to connect to the Internet and to other mail accounts with Evolution.
I've been trying to set up a mail server and I'm a bit lost on how to get it working. I'm running a centos server with sendmail and dovecot. All the guides I've read don't seem to help at all. All I want to do is set it up so that I can send and recieve email. That's all I want
the mail server itself will receive mail, that part works. i'm using dovecot imap to grab my mail, that works. but if i try to send mail from my iphone using an account on that server it doesnt work. this is what i see in syslog: May 15 07:14:52 coax postfix/smtpd[1432]: NOQUEUE: reject: RCPT from mobile-166-137-139-003.mycingular.net[166.137.139.3]: 450 4.1.8 <eppo@customconnexions.com>: Sender address rejected: Domain not found; from=<eppo@customconnexions.com> to=<xxxxxxx@aol.com> proto=ESMTP helo=<[10.25.15.47]>
I was playing with my debian server when something went totally wrong while i was editing something on my network interface,i removed those crap that i wrote and left the network interface configuration as it was
Like for example after re-editing my network interface,it was like :
As i did a network restart, i get this error saying :
There is already a pid file /var/run/dhclient.eth0.pid with pid 2802 killed old client process, removed PID file.
What is this error and how can i fix it,because every time im re booting my server i lost my network config.
Ive been running ssh to log into server for long time. Recently a x-win app reported that it suspects a man in the middle attack (MiMA), so I want to tighten this up, but it seems to me if there is a MiM, then the initial key exchange is vulnerable to a substitution. This is on solaris, but since its a basic concept I'm ot getting, it shouldnt matter,
Here's the gist of what I read:
- create users key pair, - enable host authentication (ssh_config file on client and sshd_config file on remote host) - start an ssh session and accept the remote hosts key (and I assume the remote host will take client users key and store some where)
Questions:
1. What's to stop the MIM from making a substitution of keys during the initial exchange?? Shouldn't the keys be initially transfered in a more secure fashion??
2. Does the server just accept new keys from any existing user who want to create an ssh session? So if some one knows a username and password (such as the owner of an application they know is running) couldn't they just create their own keypair and have the server accept them?

I want t desktop cube, so I followed the ..... guide here.
When I enter simple compiz config and start to change the Ultimate profile, then I lose the ability to do key commands like alt+tab and consequently I cannot use things like the switcher, or cube. The only desktop hotkeys that I can currently do (that I know of) is ctrl+alt+left/right to move to next desktop. How do I enable hotkeys to work again?
I have a problem relate to posttfix.I want to mirgare postfix mail server to exchange 2010 mail server but I can't do it,u can help me.You can show me have to do configure postfix and exchange how to?
Can this be done? A company is currently running a postfix mail server. They got a new server and, while the users are migrated, they need to have the messages delivered on BOTH servers.
I thought it could be easily done in postfix: deliver locally AND forward mail to new server, but all solutions I found would deliver the messages in just ONE place.
I have been running dual boots for a long time and never had a problem installing Ubuntu.I now tried to install Ubuntu Studio on my performance machine, a DELL Studio XPS, which has (had?) a RAID1 configaration.I got stuck in the partitioning and tried to abandon, which left me with maybe nothing... When I tried to reboot, my machine started Windows but then "autochk program not found". And I am lost for what to do...
How do I make a local mail server that itself is a client to a WAN mail server.I want the local mail server to query new mail every 30 minutes from the WAN server.

I've setup my server by following a ton of goods, and it seems to work ok, but I need to start using my server for email in order to receive orders placed via my website. I've followed this guide - [URL] I followed the steps above, and tested the mail server via telnet, and all seemed to be ok. I tried sending an email via Squirrelmail, from cs@thinclientwarehouse.co.uk TO my working email simon@c1systems.co.uk, but the server returned with the following message:
<simon@c1systems.co.uk>: host mail.c1systems.co.uk[95.128.128.129] said: 550-Verification failed for <cs@localhost.thinclientwarehouse.co.uk> 550-The mail server could not deliver mail to cs@localhost.thinclientwarehouse.co.uk.

I'm trying to execute X server (automatically), which will not bind to 0.0.0.0 (port 6000) - meaning X server will not listen on generic interface. If it's possible, I'd prefer X server not to listen at all (and communicate through other IPC if needed), is there a way to make it not listening at all? -nolisten flag or something like that? (and do it automatically, every reboot). Also, Is there a way to make X server bind to 127.0.0.1(localhost) instead of 0.0.0.0(generic interface)? It should be in one of the configuration files or the start-up command to run X.
I had a external HD from Lacie that just made me mad because you could only log into it from a windows or mac machine. So I took the 250 HD out and through it in my P3 733Mhz Processor, 128 Ram Dell optiplex. Now My Lacie HD had a Network function on it where It had a webserver and a GUI to manage users to it. But it couldn't never get the HD to turn on for Network. It would only turn on when plugged into a USB. So I want to turn my Dell optiplex into a file server with web gui functionality. How should I start.
I recently had to reinstall Fedora 11 after a power problem, and now my wife's e-mail is missing from Thunderbird.When I check the .thunderbird file in her home directory, I can see the various mail folders and the like, but they're greyed out. I can't figure out what to do to recover them. Anyone seen this before? Anyone know what to do about it
I am just checking in I know a lil about linux looking to learn more I know forums are the best way to go. I recently installed centos 5.3 on a machine we are going to be using as a squid server. Just a couple quick ?s and just wanted to pick your alls brains. What I am trying to do with the server is use it for caching to speed up our network t but I don't want to go around to all the our customers to setup their browser for proxy. What all is involved with making this server completely transparent. So the end user will does not need to enter in proxy information.
Need confirmation if the following scenario works for making my client and server as identical?
My local(source) Linux server @192.168.0.2 My remote Linux client @192.168.0.70 On the local system : #df -m Filesystem Mounted on /dev/hda3 / /dev/hda1 /boot tmpfs /dev/shm
On the local system , issue the followings to make client and server as identical : #dump -0uvf - /dev/hda3 | ssh root@192.168.0.70 -c "restore -rf - /" #dump -0uvf - /dev/hda1 | ssh root@192.168.0.70 -c "restore -rf - /boot" #dump -0uvf - /dev/shm | ssh root@192.168.0.70 -c "restore -rf - /tmpfs"
I have installed fc12 on my core2due machine, and I have installed the vmware server on it, its rpm is installed successfully with out any error, after that a message is displayed
The installation of VMware Server 2.0.2 for Linux completed successfully. You can decide to remove this software from your system at any time by invoking the following command: "rpm -e VMware-server".
Before running VMware Server for the first time, you need to configure it for your running kernel by invoking the following command: "/usr/bin/vmware-config.pl".
I tried this command and find the this message
[Akram@localhost Downloads]$ su -c "/usr/bin/vmware-config.pl" Password: Making sure services for VMware Server are stopped.
None of the pre-built vmmon modules for VMware Server is suitable for your running kernel. Do you want this program to try to build the vmmon module for your system (you need to have a C compiler installed on your system)? [yes] yes
Using compiler "/usr/bin/gcc". Use environment variable CC to override.
Your kernel was built with "gcc" version "4.4.2", while you are trying to use "/usr/bin/gcc" version "4.4.3". This configuration is not recommended and VMware Server may crash if you'll continue. Please try to use exactly same compiler as one used for building your kernel. Do you want to go with compiler "/usr/bin/gcc" version "4.4.3" anyway? [no] yes
What is the location of the directory of C header files that match your running kernel?[/usr/src/linux/include]
Now it asks me in last lines that "What is the location of Directory of C header files that match your running kernal?"

I've just upgraded to 11.04 and I created a evolution-backup.tar.gz file as I've done in other upgrades. When I restored the backup and started Evolution, I've lost all the emails in top-level folders (Inbox, Sent, Drafts etc). My own custom folders within these top level folders contain the emails that I backed up. There are quite a few important emails that I've yet to respond to in my Inbox and this is very concerning. Also, I've lost all my Contacts!
