so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens
I am re setting up a server of mine running red hat enterprise Linux server 6 and I had all of this working befor but for some reason I had troubles getting sasl to work and now when I login my smtp server I get an error stating that my username or password is incorrect though I am sure I am entering both correctly. Would anyone know what could be happening? I have been spending days on the web looking for the solution and only went from sasl not working when started as a service to this. For some reason I can't use Pam with saslauthd and had to use shadow instead of which from what I hear I get to use better methods of secure authentication with smtp
I am new to Linux and I am trying to set up a mail server using postfix. I have done all the configurations(hopefully correct) and all the test seems to work except 2 things.
1) Postfix is running but when I try to restart the service it always fails. I checked the /var/log folder and there are no error messages. 2) When I try sending e-mails using outlook, outlook fails to connect to my server.
I am wondering if I have done the configurations properly. I am a little confused in regards to hostname and domain name. When I do a hostname on the terminal I see the hostname that I gave my server. When I do the domainname command however, domain is none. Is it necessary to have a domain to configure postfix? I have myhostname = my.hostname.com what should my domainname = to if there is none. If I do require a domain name how to I create one? I need to be able to access e-mail from external clients.
Tearing my hair out on this one a little bit, having problems sending message from web based PHP form to user inbox.I keep getting: Undelivered Mail Returned to Sender<email@example.com>: Host or domain name not found. Name service error for name=mydomain.co.uk type=A: Host not found.Running these commands:
I am in the task of migrating old linux to new linux which centos 5.5. while moving out all apps ,data etc.I need to configure SSL in apache.I have installed mod_ssl with apache 2.2. i went though some docs to configure with certificate that I have . Not sure how to start the service in 2.2. The apache/SSL was configured in my old server which apachectl. SO after importing certificatr , I do ./apachectl startssl to take in effect. In my new server , the http service is /etc/init.d/httpd, not sure how to start SSL service in centos 5.5.

i am using RHEL5 at VirtualBox,at the time of installation i did create two partition one for / and another for swap.Now my /var directory is taking too much space and i decided to create a new partition with required size and mount that partition to /var.Now http service wont start and i did not reboot yet.
Ok, so I have installed apache 22, mysql5.0 and proftpd1.3. When I reboot my server, the above applications do not start up automatically, and I have been trying to figure out how with out much success. know that I need to make some changes inside the init.d directory on my CentOS Server.I am running CentOS 5.4 x86_64 build.I really am not sure how to accomplish the task or where to start.
I am using Rhel5 and I'm new to linux so pardon me for sounding a bit green around the ears.Anyway..I got an error message a few weeks ago about how the start up script that displays icons on the far right of my start panel was malfunctioning and it was going to be deleted from the start-up. didn't really know what it really meant and I just clicked ok.wireless eth0 status icon as well as my amarok status icon are hidden on the start panel. How do I get it back/add that script back to the start-up
On the other thread, we (read: me) went off topic of that request, therefor i want to make an extra thread for this. The request is quite simple.
1) When i login to my DE (LXDE) i want to have several applications start automaticly.. Status: Done.
2) Now, i want them to be started on other displays/desktop, the virtual desktop ones, those you access with ctrl+alt+arrowkey. Status: requesting
I had figured that there's an option to those applications i'd like to be started, display=.However, starting up these apps with the display argument, causes graphic errors on LXPanel and causes an error, rather than to be display on current desktop.
I recently moved over user from an old box running postfix(v 2.0.16) over to rhel 6 running postfix (v mail_version = 2.6.6). ive tried to make sure all the files are of correct permissions and that the main.cf file is configured corectly. However there is something wrong as when i run postfix: service postfix server i get no error but when checking the status:service postfix status i get: master dead but pid file exists Looking into /var/log/mailog i find this line being the issue:
Don't know what is going on here, but Evolution won't start. I've tried reinstalling. When I click the icon to open it, the little loading cursor displays for a few seconds then it disappears and nothing else happens.
make install then i got this error: postfix: fatal: chdir(/usr/libexec/postfix): No such file or directory make: *** [install] Error 1 I don't understand why it's checking the usr/libexec folder for the daemons although I've set the folder to /opt/product/postfix-2.6.5/libexec in the makefile. Here is also the cat of my makedefs.out:
recently we decided to make our own panel (like Plesk or cPanel) but for Ubuntu and it will be licenced under GPL (like any other professional sofware).want to make a panel not only that fits our needs but also the needs of other system administrators and domain owners. We researched other panels and found out that non of them has security/look/ease of use in one package. Bad codig is another problem found in other panels.I made a short overwiev of what I think we have to have in the beginning.I Security :1. Completely chroot enviornoment where every single service is in chroot mode (bind,mysql, postfix, .... )2. Easily managed IPtables trough web-based interface. 3. Coding rules has to be strict.
II Software selection : 1. MTA - Postfix 2. POP - dovecot
