Sending Mail From Command Line

I searched the forums for my title and I am not finding exactly what I am looking for. I am not using a program to send mail, such as Thunderbird or whatever. I simply want to be able to send mail from my Ubuntu 14.04 DESKTOP version for logging. I use a program called Logwatch (used alot in RHEL or CentOS) to monitor the server itself. The program sends mail to the root user account on the machine, which I can check and see, and within the program conf file, I can add an external email address, but it never sends.

I'm familiar with the SMTP concept of sending mail, outgoing mail server authentication, etc. I don't care to run this box as an SMTP server, but I understand that I need some sort of SMTP or MTA program to send mail into the real world. I tried Postfix but couldn't get that to work, and the Logwatch program wants to use sendmail, so I installed that but I am having the same issue. I am sure it is a step I am missing.

I also can't figure out how to get the 'mail' cmd from Terminal to work. I use this command:
Code:
mail -s "test" | /usr/sbin/mail myemail@domain.com

it follows through the subject, CC, body, but when I try to hit either . or CTRL-D, it never sends the email, in fact is does nothing.

I also tried sendmail with this command:
Code:
sendmail -v my@email.com < /dev/null

I was just trying to send a test email. It logs into my SMTP mail server, which I already configured, and it tells me to type out the mail, then end with a "." by itself on a single line. I try this and it just sits there.

I am missing SOMETHING when trying to actually send the mail. I can get it written with subject and body, connected, but it never sends and I am probably missing a / or something.

I did find and follow these instructions, but it still isn't working with sendmail. If I need to go back to Postfix, I can do that, I don't honestly care what I use, I just want some programs such as Logwatch to be able to email me.

Telnet / Postfix Connection Refused Question For CENTOS 6.4

Good Morning! I am supporting the coffee and Doritos industry with my frustration with this problem. I have been battling it for two months. I have several Red Hat books, the official Red Hat study guide, and have searched the forums for weeks with no avail. I was wondering if you have ever had this?

I am trying to "telnet server.example.com 25" or telnet in general. Both servers are running on a KVM on the 192.168.122.0/24 network.


[root@server ~]# telnet server.example.com
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
Trying 192.168.122.191...
telnet: connect to address 192.168.122.191: Connection refused

I can ssh, run NFS, and also run internal postfix e-mails.

IPTABLES IS TURNED OFF ON BOTH CLIENTS

Postfix and Telnet is configured on both clients, with both listening:

[root@server ~]# netstat -tulpn |grep :25
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1802/

When I Telnet from client named 'Server' to client named 'ISCSI', tpcdump on client 'ISCSI' gives the following:

19:01:23.579330 STP 802.1d, Config, Flags [none], bridge-id 8000.52:54:00:2e:85:0e.8003, length 43

Grep Output Of Command To Return 1 Or 0 For If Then Statement

So, I'm new here. Was thrown into the deepend (read: shallow pool) of linux administration of a few centos 6.5 servers in October, and I've been pretty slow on the uptake. Years of Windows administration and desktop support will do that I guess.

So we have qmail on our prod servers that send out messages for our webapps. Postfix failed last night on a prod server, and it occurred to me that it's happened a few times since I've started, and instead of waiting for clients to tell us, I should be more proactive. I came up with/begged/borrowed/stole a quick script to check to see if postscript was running, and if it was, restart it, and contact us. This was to be run from jenkins.

Quote:
if (( $(ps -ef | grep -v grep | grep postfix | wc -l) > 0 ))
then echo 'Mail is up.'
else echo 'Mail is down! Attempting to restart service...'
service postfix restart
fi
The question was then raised about an unresponsive process (zombies!), and I figured it might be a better idea to use postqueue -q, or mailq to either see a Mailbox is empty, or look for fatal if postfix is off or unresponsive. This is where I ran out of coffee and went over the deep end.

To get this to work, I thought it would be a good idea to run two scripts. One to check if the mail queue is empty, and if not, send up a flag. The next was to run a few minutes later to check and see if the mail queue was throwing up a fatal error, and if it was, throw up a second flag, which sent out an email from jenkins. Incidentally, if the mailqueue were clogged, this would also trigger an alert. Our mailqueue doesn't get a lot of traffic.

First command. Returns then and else statement without issue.
Quote:
if ((mailq | grep 'empty') < 0 ); then echo 'Mail is up.'; else echo 'Mail queue is not empty. Please check mail server'; fi
Second one... Not so much.
Quote:
if (mailq | grep 'fatal') < 1; then echo 'Mail is up.'; else echo 'Mail queue is not empty. Please check mail server'; fi
You can probably suss out what I'm trying to do here, even though I'm not doing it right. Any ideas? I know this is newbie stuff, and I appreciate your taking the time to read this people.

Sendmail Is Not Working

Hi all,

I am trying to configure sendmail on my OEL 6.5 running on VM.

I did below to set it :

1. # yum install m4 telnet mailx
2. # yum install sendmail sendmail-cf
3. # ps -ef | grep -v grep | grep -i sendmail
root 3805 1 0 05:58 ? 00:00:00 sendmail: accepting connections
smmsp 3815 1 0 05:58 ? 00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue

4. # netstat -an | grep :25 | grep tcp
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN

5. vi /etc/mail/sendmail.mc

From:
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

To
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

6. # m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

7. # service sendmail restart

8. # vi /etc/mail/local-host-names
oracle.com

Now if I am sending mail from 1 user (root) to other user (oracle)

$ mail -s "Test mail from root" oracle
Hello this is the test mail
.
EOT

and checking mail log under /var/mail/oracle, its passing successfully.

But when trying to send the same from root user to my company outlook account not gtting any mail.

Sending Mails With Port Number 587 Bash Script Help

Hi All,
We have some shell scripts which will send emails about backup, alerts etc using mail command. Example.
Code:
echo "Test Mail" | mail -s "Test" me@mydomain.com

I guess the above command just connect port number 25 of our mail server even if we do not define any port number. Now I would like add smtp port number as 587 in all of the bash scripts. I googled for this but could not get whatever I am expecting. So expecting your kind reply to define smtp port number as 587 in all of the bash scripts.

Thanks in advance.

New With Sendmail, Not Receiving Mail After Sending

I'm new to Sendmail and I want to be able to grab various stats from the Linux servers that I manage to monitor them.

Sendmail is running on my main Linux server and I can go thru the motions of sending an email to my MS Outlook client, which is what I use at work.

However I never get the email and if I check /var/spool/mqueue, I don't see any email queued up, and if I put a tail -f on /var/log/mail, this is what I'm seeing:

Code:
Feb  3 10:20:38 computername sendmail[31432]: t13GKcri031432: from=cmmiller, size=77, class=0, nrcpts=1, msgid=<201502031620.t13GKcri031432@mailserver.com>, relay=cmmiller@localhost

Not sure what to troubleshoot here, and if anyone can point me to better information, thanks.

Xlib: Connection To ":0.0" Refused By Server Xlib: No Protocol Specified

hi all,
I'm new here.
I have similar problem with running a C project that uses GLUT/OpenGL graphics...


every run result with the two lines:

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

sometimes the graphics works ok sometimes there is an infinite loop, but every execution result with the two lines above.

what is the meaning of these 2 lines?
Is it an Error or Warning?
How can I fix the code?

My guess is that there is a fundamental problem with the graphics Glut Library...Or that I didn't write the MakeFile OK

Please help me, I would extremly appriciate it.
Jonathan

Cannot SSH After Changing Permissions In Root Folder

Hello Guys,

Im fairly new to linux and was mucking around with permissions on root the other day and lost my connection via ssh. Now when i try to connect via ssh I get an error 'connection refused'. My system logs show the following:

Starting sshd: /var/empty/sshd must be owned by root and not group or world-writable.
[FAILED]

I gather this is because I changed some permissions on root. Thing is, as Im unable to connect via ssh, how else can I correct this issue? Im desperate as I have some data on there that I dont want to lose.

Thanks
Mark

Postfix Email Not Working In Oracle Linux

I have setup postfix in Oracle Linux VM in virtualbox to test simple email sends that I am sending it to my personal email.

I have configured the following in main.cf file

myhostname = abc.testserver.org
myorigin = $myhostname
inet_interfaces = localhost
#relayhost = localhost.localdomain - I have this commented as of now, but I tried with the localhost.localdomain, IP address and none worked. I also do not have my ISP's server details and I also do not want to use it.

I checked the /var/log/maillog and I see the following

Code:
May  4 17:25:37 oim sendmail[31684]: t44LPbKA031684: from=root, size=72, class=0, nrcpts=1, msgid=<201505042125.t44LPbKA031684@localhost.localdomain>, relay=root@localhost
May  4 17:25:37 oim sendmail[31685]: t44LPbSn031685: from=<root@localhost.localdomain>, size=378, class=0, nrcpts=1, msgid=<201505042125.t44LPbKA031684@localhost.localdomain>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1]
May  4 17:25:37 oim sendmail[31684]: t44LPbKA031684: to=abc@abc.com, ctladdr=root (0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30072, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (t44LPbSn031685 Message accepted for delivery)


I can also see the messages in /var/spool/mqueue/. The telnet to the localhost 25 port also works. Is any of the config settings wrong?

Thanks.
