I've recently had to rebuild our mail server - after the old one over heated - and I've realised I never backed up the config files for exim... so now tyring to work out how the hell to configure what I had....
The setup isn't the most straight forward, so I'll try and explain what happens...
- all emails @longdomain.com are received by an hosted server on the internet
- they are then forwarded to @shortdomain.com, the IP for which is our internet connection which fowards port 25 traffic to the exim server
- the exim server then spam and virus checks the emails and forwards them to an exchange server (sorry but it works well for us)....
I've installed exim4/spamassassin/clamav successfully, and it's setup to receive emails for the relevant domains and relay from the hosted server on the internet (and some local addresses).
how I then setup exim4 to foward all emails on the relevant domains to the exchange server?
I have tried to set up the desktop version of the server . In my apache2.conf file I have changed the following lines-
Code: # Include the virtual host configurations: #Include /etc/apache2/sites-enabled/ Include /home/www/websites/ Yes I do keep the default values commented out
In my virtual host file I have made the following changes to the DocumentRoot, and to one of the <Directory>; the rest of the file doesn't appear here as nothing was changed.
(Desktop with Debian sid) How do I configure Exim4 to send local mail locally and other mail through my ISP? I just did dpkg-reconfigure exim4-config and none of the choices seemed to give me the answer. I have a lot of frozen email addressed to: root@<My_ISP_SMTP_URL>. I also don't know what happens to regular email sent from Mutt. I have no problem sending email through my laptop on the same LAN.
Using httpd - everything usually works but I have written a cgi script and placed in cgi-bin but i cannot access this dir and keep getting forbidden messages. I have tried adding my root and usual user to the /etc/group file against the user stipulated in the httpd.conf file but i still can't access the cgi script i wrote (in browser - localhost/cgibin/myscrippt.cgi) when i place it in the cgi-bin under htdocs. i have also chmod 755 directory and files.
I'm trying to set up a *simple* MTA in my local network. The only thing it should be able to do is send system / daemon mails to admin@mylocaldomain. but at the moment I'm pretty much overwhelmed by everything i *should* know in order to set up this MTA
I configured exim to be in "internet"-mode. now i have a variety of errors I can choose from (and a variety of solutions that i don't like ).. my test is always an email from test01.mylocaldomain:
echo "Hello World" | mail -s Testmail admin@mylocaldomain
- after running the config, i get the error: admin@mylocaldomain: all relevant MX records point to non-existent hosts --> google says, edit and udpate update-exim4.conf.conf --> dc_relay_domains='mylocaldomain' --> but this exim installation should not be a relay at all. it should only be able to SEND (to this domain), not deliver it. or do i get something wrong?
- after i added dc_relay_domains='mylocaldomain', i get --> SMTP error from remote mail server after RCPT TO:<admin@mylocaldomain>: host mail.mylocaldomain [192.168.x.x]: 550 5.1.1 <root@mylocaldomain>: Sender address rejected: User unknown in virtual mailbox table --> but i don't want to create an account on the mailserver for the SENDER...
- ...so i thought, i'd config exim with the domain "test01.mylocaldomain" (including the server name), so that the sender is clearly from another domain than the mail server handles (e.g. user@test01.mylocaldomain).. but then i get this --> SMTP error from remote mail server after RCPT TO:<admin@mylocaldomain>: host mail.mylocaldomain [192.168.x.x]: 450 4.1.8 <root@test01.mylocaldomain>: Sender address rejected: Domain not found
I really just wanna send mails in my local network.
My ISP recently decided to kill outbound traffic on port 25 for some reason. Therefore, I change the SMTP port to 24, everything work fine so far i can send email to local domain and remote. However, i cannot receive Emails from remote domain. i try use online "mail server test services" and all i got is timeout.
I'm more of a CentOS person, but after some issues on my new box I switched to Ubuntu server. I am working on getting it setup as a mail server (mainly for testing at the moment and soon be live). I performed apt-get install sendmail then apt-get install exim4 and got the message:Could not perform immediate configuration on 'exim4-daemon-light'. Please see man 5 apt.conf under APT:: Immediate-Configure for details. I have Ubuntu Server 10.10 32-bit on a Dell Intel Poweredge.
I am working on a Debian 2.6.26-19 Distribution with exim4 as MTA. After a system restart a problem occurred with delivering emails to local addresses. These local addresses use a 1and1 mailserver for email. The MX records for the local domain are set correctly but exim does not use a DNS lookup for these addresses because it identifies them as local addresses. I figured this out by executing the exim4 -d -bt command. The dns lookup part of the result looks like this (I replaced the actual address with placeholders):
[Code]....
The eventual result of the exim4 -d -bt command is: [user]@[domain.ext] is undeliverable: Unrouteable address How can I make sure, that exim4 makes a DNS lookup for the local addresses instead of skipping it? I know that I have to edit a exim4 configuration file, but I could not figure out which and how.
I set up a dynamic DNS address for my home network. Let's call it [URL]. Then I set up one of my machines with a bind9 DNS server and pointed my router's DNS setting to it. I did this so that I could resolve awesome.server.com from machines inside my network and have them correctly find my server. Then I set up a second machine to serve web pages using [URL]. I did this by forwarding port 9200 on my router to port 80 on that machine. This works, but of course, it only works from outside my network.
What is the best way to get [URL] to work from inside my network?
I've tried setting up the iptables on my server to forward that port, but it just times out. I used these rules that I found by searching the internet:
Code: iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 9200 -j DNAT --to 192.168.0.300:80 iptables -A INPUT -p tcp -m state --state NEW --dport 9200 -i eth1 -j ACCEPT
However, those rules might be failing because they are intended to forward ports requested from outside the network. I must admit, this iptables stuff is way, way over my head. Is there a different method that I must use to make it work inside my network? Or is there a better way besides iptables?
I am trying to run xeyes on a remote machine via ssh connection. Both my local and remote machines are Ubuntu 10.04. I connect to remote server via ssh -X and It does not forward to display to my local machine...
Code: root@goliath:/opt/install/bits# ssh -X -l root duke root@duke's password: Linux duke 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:10:02 UTC 2010 i686 GNU/Linux Ubuntu 10.04 LTS [Code]....
From this thread I've decided to try add a feature of removing local port forwardings in ssh.Here are some very ugly and not-yet working hacks what I made so far:
* Patch for channels.c * Patch for channels.h * Patch for clientloop.c
I was clearly expecting this to work without any troubles-everything seem to be logically correct, but I made a programming mistake somewhere: don't know where, maybe you will point me to this?Many sites say there is a WAY AROUND with -D param(starting socks proxy as a tunnel-generator), added since 5.2, but I don't need that way around. I need a way through. I use exact ports for exact services and if I want to change it runtime I'd like to have ability to do so.If you have other ideas or points instead of coding this, please share them here & here(original question).
I have a postfix mail server on ubuntu 10.04 lts behind a router. so all local users are fetching/sending mails through ms outlook using local IP. Sometimes when internet goes down and any mail send then it bounced back immediately saying domain not found. Can u please tell me how i configure to hold all mails in postfix server rather than bounce when internet fails and will pass through when restored the internet around 15-30 minutes?
I have a ubuntu server 9.10 installed with exim4 as MTA. I configured a mail address on it (let's say me@example.com). Before i had it working i had a other email configured (let's say me_2@example.com). At the time i had this one it didn't work i removed exim4.
Now i can successfully send mails with it by the configured me@example.com. I also configured the password for this, but when i receive the mail the old configured mail is presented as "from" (so from: me_2@example.com).
Anyone knows how this can be changed so it says the mail is from me@example.com? The mail is not an alias, and in a mail client they work separately.
I've successfully compiled a local gcc(s), but now I want to have multiple versions (which is easy enough), but one in particular, I want to be 32-bit. This one eludes me.
Can anyone suggest what to do in order to compile a 32-bit version of the gcc that I want? All the other versions, 64-bit, compiled no problem.
I have two machines on my local netowrk, one running Fedora 9 and the other Fedora 11,(64 bit version).I made one, machine A, into an NSF server and arranged to export a directory to the other machine B.I made sure the firewalls were allowing nsf traffic, and I restarted all the relevant daemons.But the mounting still doesn't work.I looked at the setup on my Linksys router, but I don't see anything obvious there that might be getting in the way.ping and ssh recognize my names for the two machines and work properly, bu t I've also tried using the numeric local ip addresses.I tried with the program showmount on B to see if there was any connectivity and I getB% showmount -e Aand I get the responseclint_create:RPC: Port mapper failure - RPC: unable to receive.I used to manage a departmental network and set up nfs mounts all the time, but things were simpler then. I am at a lost what to look at next
I'm trying to set up my mythtv backend on a headless box. The many tutorials out there tell you to run mythtv-setup from a machine with a display by x forwarding through ssh.
Code:
ssh -X username@ipaddress /usr/bin/mythtv-setup
The x forwarding works fine except that the first part of the mythtv-setup requires you to stop the mythtv-backend process which you have to do as root. It brings up a box asking for your password (much like is would if you just typed sudo xxxxxxx in the terminal) but it won't accept the password. Looking in the auth log it seems that it can't authenticate
Now I know that my account (administrator) can have root privileges because I can sudo xxxx to my hearts content via ssh in the terminal, but it seems to not work when it's being requested from a forwarded X window....
Trying 192.168.100.9... telnet: Unable to connect to remote host: Connection refused
[Code].....
This last one is strange as I the IP looks odd.
What I am doing wrong, and how do I fix it. After much surfing many mosts say that telnet is not used anymore but I want to use it to test my smtp server.
Epson stylus d88 recognised by 10.04 no tests or maintenance available in local host and obviously not printing. It's like it's there but they cannot talk to each other
I am using nagios to monitor a local host and a remote host in a vmware, where both the machines working in CentOS. Now i need to monitor MySQL in my local host so that i should know whether MySQL is up and running. I came across some plugins like
Pre-exsisting issue from 9.04 server, and has never worked right for me. When I try to open an X11 forwarded app on a mac using the command "ssh -X myusername@serverIP" Other linux machines have similar issues from terminal. I can login just fine and preform any actions I want that do not require X11 forwarding, like say firefox or a manager. I just get the error "Error: no display specified" when trying to do anything with X11 forwarding. I have almost no Linux experience but from tinkering and my friends tinkering wonder if I have a x authority issue.
At one point I had ubuntu desktop package installed (forwarding still did not work then), did a unclean uninstall of it installed Xubuntu. Xubuntu did nothing but throw fits saying I did not have authority to preform all sorts of actions, many relating to root access. This box is meant to be a headless file, print and web server with the ability to login remotely as a convince for administration. I have given up on having a working GUI of any kind on this box. I really do not want to reinstall because of the amount of data on the main partition. What can I start trying to look into?
I have set up 10.04 server, got userdir working (/home/username/public_html) so I can access it with h ttp://myipaddress/~username. What do I need to do to get mydomain.com to point to http://myipaddress/~username?
I just bought a domain, let's say it's called example.com
I also have a gmail account, let's say it's: my.account@gmail.com
I want all email to master@example.com to forward to my.account@gmail.com, and likewise I want all e-mail from my.account@gmail.com to be from master@example.com, and have the reply-to also be master@example.com.
I guess the most pressing issue here is setting up some proxy to forward all my @example.com emails to my gmail. I've been looking through the forums and reading some tutorials, but none of them seem to do exactly what I'm looking for.
At first I want say that I'm regular Ubuntu user, not system administrator. I have installed mail server using Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 11.04). And it's work!
But I have a challenge. I need to get incoming mail (from another server), zipping mail-body (as html or text) and all attachments into zip-archive, compile new mail with this new attachment (zip-archive) and (most important!) sign all this email with signature which locale in pem-file and send it to BCC-address from incoming mail. I don't know how do it or which tutorial start to read.
I have a strange iptables issues. I have just built a new Debian install and starting adding some real basic rules (see below) the problem seems to be that the localhost itself can't get any returning traffic. That is, it seems to be allowed outgoing traffic but not the connected, returning traffic. Ordinarily allowing Established Connections would resolve this, see the rule below, but it hasn't. Why this doesn't work. Removing the last DROP in the INPUT chains obviously makes the traffic work!
