Sendmail (pid 13090 13089 13082) is running...
I have installed postfix and dovecot on my server and thought postfix will not only take SMTP connection from my e-mail client like Outlook, but also handles "mailx" commands from the server. However, it looks like sendmail is still responsible for sending mails from "mailx". I tested this by turning it on/off using "service sendmail stop" and "service sendmail start". Mails sent using "mailx" will only be sent when sendmail is up. When I did "yum info sendmail", it lists sendmail as an installed package. Is is safe to remove sendmail by running "yum erase sendmail", and let postfix handles "mailx" also?
View 3 Replies View RelatedI'm building a new machine with slackware 13.37 64bit and so far all has gone well except for secure smtp. My previous setup was with slackware 13.1 32bit which worked fine. If I run with (`confAUTH_OPTIONS', `A p y') in my sendmail config it shows "AUTH warning: no mechanisms" in my maillog and obviously fails to authenticate. When I take the 'p' out and run with (`confAUTH_OPTIONS', `A y') then it does list the defined confAUTH_MECHANISMS and works. I would prefer to run with the 'p' option and require the security layer.
Most of my setup guidance has come from the "Sendmail SMTP AUTH Howto":
http://www.linuxquestions.org/questi...-howto-224543/
The Sendmail "TLS SASL SMTP-AUTH" page on slackwiki:
http://www.slackwiki.org/Sendmail_TLS_SASL_SMTP-AUTH
And this page for debugging "How to test Sendmail SASL Authentication":

My hope is that I'm just missing something simple. Does anyone have insight into why adding the 'p' to confAUTH_OPTIONS is causing this behavior?

My goal is to be able to send mail remotely with secure authentication. If the way I'm trying to go about it is old and there is some newer/better way I'm happy to go with that - but sendmail/saslauthd has worked for me in the past.
Sendmail is version 8.14.4 and looks like it has the necessary options compiled in:
Code:
saslauthd is version 2.1.23 and supports shadow:
Code:
I did discover the need to link /etc/sasl2 to /usr/lib64/sasl2 and created the Sendmail.conf file there:
Code:
Here's the sendmail configuration script I'm using. Its really just the vanilla /usr/share/sendmail/cf/cf/sendmail-slackware-tls-sasl.mc file with my cert file names:
Code:
When I try to connect with (`confAUTH_OPTIONS', `A p y') in the config here is the output I get in maillog (none of the other logs seem to show anything and I dont see any errors/warnings when I restart sendmail):
Code:
If I change the option so its just (`confAUTH_OPTIONS', `A y') then it does work and this is the log output I get:
Code:
My client is configured to use SSL and when I go through the setup, it does appear to authenticate against the smtp server and it validates. The fail comes in when trying to actually send mail.
Does anyone have insight into why adding the 'p' to confAUTH_OPTIONS is causing this behavior?
Checking the process table for the running sendmail, I would like to know the full path to the sendmail binary a la the ps -ef on a Sun or other servers. How do I get ps to give me the actual path, or should I use a different tool on my Linux servers?

I am using webmin for my daily tasks. I have fedora 13, whenever I click on ''Sendmail M4 Configuration'' or Outgoing Addresses (generics)'' I get the following error message
Quote:
The Sendmail M4 configuration base directory /usr/share/sendmail-cf was not found on your system, or is not the correct directory. Maybe it has not been installed (common for packaged installs of Sendmail), or the module config is incorrect. I read documentation at sendmail.org, it seems that structure of directories for send mail has been changed in version sendmail-8.1.4 shipped with FC13. In webmin config module we have

Sendmail M4 base directory = /usr/share/sendmail-cf

I have been trying to set up ssmtp so I can send email using Gmail's ssmtp servers. However, when I try to send mail (using mailx), I get the following message:

I recently modified sendmail.cf to use a third party SMTP server to send emails. It works great. But when I run sendmail from the command line, I have to specify the -C flag and force feed it the location of my sendmail.cf, or else it doesn't work.
So in other words, the following works great:
However, if I don't specify the -C flag, sendmail doesn't consider what's in the sendmail.cf and barfs:
I don't run sendmail as a daemon. I'm only using it to send emails. I know my modifications of sendmail.cf are correct because it works perfectly when I use the -C flag. I searched my disk to see if I could find another sendmail.cf on the machine and only the one in /etc/mail came up.
Why sendmail is not reading my sendmail.cf?
I'm running Sendmail version 8.14.2 on Fedora Core 8.
Brand new to Linux. Sort of got thrown in front of the bus if you know what I mean. The company I work for has a Linux server running CentOS 5.4 Company uses Linux for their Email, FTP and Web Server. Have been here a few years dabbling in and out of Linux and now that the old Admin has left the company.....I need to learn it ASAP. The server has run pretty solid until today.
The email server runs SendMail and SpamAssasin. Received lots of complaints today regarding extra SPAM. Noticed that SpamAssassin was not running. Tried to restart it through the WebMin tools and got the following error: Starting spamd: child process [3956] exited or timed out without signaling production of a PID file: exit 255 at /usr/bin/spamd line 2588.
I have bees assigned a problem which states that :
sendmail-2: Wrong number of instances of process sendmail:, expected instances equal 1 but found 0
THats it...what exactly this means and how should i proceed for solving this problem...

However, I would like to be able to hear it all the time. I don't want to have to record to be able to hear it. Is there a way to mix the line input sound with the normal system sounds?

I want to use Ubuntu, but I'd like to listen to my favourite audio stream like I do for Windows.I have installed Audacious from the Synaptic Package Manager when I found out that my new Ubuntu installation didn't install an audio device as part of its installation, and then I installed something called 'Xine' as prompted when,after I went to the home-page of my audio source,I discovered that I needed to install some extra 'codecs'.However, I still cannot get the familiar noise that surrounds me when I'm working within Windows to play on Ubuntu. No noise is produced. What's going on?

I am using ubuntu 8.04 with firefox browser.
There are some sites which allow you to listen the mp3 song like [url]
I have found the most simple way to get mp3 file
(1)Sometimes you get address ending with .mp3 so just copy the whole URI and use in terminal wget "PasteWhatYouCopied"
(2)But in the link I have mentioned there is no mp3 link in address bar.
Here I found out in totem-plugin-viewer(that is the thing that plays your file in browser).Just Click the button next to sound and select copy
In example taken above it is [url]
And use just like before wget "PasteWhatYouCopied" -O output.wma
Also notice that you have the song as output.wma in current folder of terminal.
(3)If there is a video on webpage then either wait for it to get completely downloaded & get it from /tmp.Remember don't close the page till video gets downloaded completely & you copied it from /tmp then only close that tab.
(4)There is a firefox addon 'unplug' which can help for flv because after sending file to download via unplug you can close that tab.

View 1 Replies View RelatedI am trying to get my own email server set up, and so far its been going pretty smooth, The only thing that is not working right now is receiving emails. I can send email just fine, and when they are sent they are even sent from the proper addresses, but when I try to send an email to my domain, it does not go through.
I have the port forwards set up on my router to send all traffic on port 25 over to my mail server, I can telnet to the smtp server from the localhost just fine, but when I try to telnet from another computer on my network it gives me this message

So I ran a netstat -an on my mail server to see what ip address smtp is listening on and I get this result

Now most guides I find for this problem just say to un comment the line in the master.cf that says "smtp inet n - - - - smtpd", the problem is that line is already uncommented and I am still not able to telnet to port 25 from any machine on my network.
Here is my main.cf, tell me if there is anything that I can do.

I have Lenovo T61 with opensuse 11.4 which until this morning was working just fine. I have used OpenSuse on this notebook for about 2 years with out much trouble. This morning on boot up I could not login because GDM was not listening to the keyboard for some reason. I rebooted on a live disk and the hardware was just fine. I switched to init 3 in /etc/inittab and the keyboard was working fine. If I started X with startx it still worked fine. If I started gdm the keyboard was not working anymore, so much so that I could not do {ctrl}{alt}{F1} to switch to a virtual terminal or {ctrl}{alt}{bksp} to kill X, nothing. The mouse worked so I could reboot.
I installed KDM and switched to it instead of GDM for the display manager with yast and was able to login and everything is fine. I would like to switch back to GDM but it is not that big of a deal

View 9 Replies View RelatedI'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.
