Sending Mails With Port Number 587 Bash Script Help

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.

Hi All,
We have qmail server running on RHEL6.5. We have already made sure that our server is not acting as an open relay with the help of http://mxtoolbox.com/diagnostic.aspx.
But still anyone can telnet to our domain and send fake emails to anybody@ourdomain.com. For example Code:

telnet mail.ourdomain.com 25
helo mail.ourdomain.com
mail from: unknown@anyname.com
rcpt to: anyemailid@ourdomain.com
data
from: "Any Unknow name" <unknown@anyname.com>
to: "Some user Name" <anyemailid@ourdomain.com>
subject: Testing MTA with telnet

Hi,
This way anybody can fool us.

Regards,

.
quit

So can anybody pls help me to prevent this. I meant to say, we should not block port 25, instead it should verify whether or not "from email id" is exist in our domain, if it is exist then it should ask for the password also or if it is not exist then also it should not take us to next step. Because as per above example anybody can fool us as the mail is coming from outside but it is just from our domain to our domain without any authentication!!!
Expecting your kind help to block sending mails in this way.

hello

first year of learning linux and bash script
Now i wrote a bash script with a function.
Today i recieved a email from my teacher that 1 function only can have 1 command and no more then 1?

thats a part of the script

Code:

function tx_unreachable_msg()
{
LOGLINE="[$DATE] no ip service unreachable"
typewriter "$NOIPSERVICE niet bereikbaar" .1
sleep 1 
typewriter "Mail wordt verzonden naar $email" .1
mail -s "NO ip mail error" "$email"<<EOF
dynupdate.no-ip.com niet bereikbaar @ $DATE
EOF
}

it's part dutch part english but the point is that the first LOGLINE is forbidden in the function because i use the functie to send a mail end not to write a logline but that's a part of the command in my case?

So what does this function?
If the no ip service is unreachable then it's write to /etc/var/log/no-ip and after the sleep it's send a simpel mail to the adres in the variabele mail.

i read here at the first line:
Quote:
Shell functions are a way to group commands for later execution using a single name for the group.
so is it true that my function is wrong and so no can someone point me to a website where it's say that more commands are allow in 1 function0

Hi All,

I have two scripts, the aim of these two scripts is, to check whether a particular script is running or not, if it wont runs, then throw a mail.

How i Achieved this output is, I wrote first script.

I created an infinite while loop which performs below steps

1. It creates a touch file
2. Triggers the script which needs to be monitored if its working or not.
3. Removes the touch file.

If the second step fails, then the remove file command will not happen and the script will stuck there itself.

I created an another script which checks the creation time of the touch file and if it is more than ten minutes, it means the second step in the first script is hanged, which also means that particular script is not working.

So if the creation time is more than 2 minutes the second script will throw a mail.

Below are the two scripts.

Code:

#!/bin/ksh



userid="chansd"

filename="/apps/log/check.txt"

while true ;do
touch $filename
pass=`/apps/eDMZ/call_st.ksh $userid`
sleep 20
rm $filename
done

Below script checks the file creation time and throws email if it is older than 2 minutes
Code:

#!/bin/ksh


filename="/apps/log/check.txt"

if [ -f "${filename}" ]
then
if test "`find $filename -mmin +2`"
then
echo "script is not working ! Please act on it" | mail -s "Script  is not working" Example@mail.com
fi


else

        exit 1

fi

What im going to do is

1. I am going to run the first script in background so it runs forever.
2. I am going to run the second script in cron forevry 5 mins to check the file creation time.

3. So if the first script hangs . I will kill the process using process id and after the issue resolves with the inner script, I will run the main script again.

I am new to Linux, Please let me know if this approach will work as expected.

i have been trying to get this peice of code to work but i cant seem to get it to work.
im just starting out coding and kinda poking around in the dark to get this resolved, any help would be much appriciated, thankyou

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.

mail -s "Test mail from root" abc.xyz@aaaa.com (trying to send to my outlook account)

Getting below error on /var/log/maillog :

Please suggest if something I missed out or any other problem

Thanks,

Hello, I have an expect script where I ssh to a remote host to determine the network configuration and get from the user the network interface card that should be used. From their response, I determine the subnet mask and save the information to a text file that is later transmitted back to my local host. This is all so that I can set up virtual IP aliasing and verify that the physical IP address of the local and remote host are on the same subnet prior to continuing with the setup. I am running the script on Linux, with expect version 5.45.

The code itelf works just fine, but I'm having some issues with how it displays on the screen. As you'll see below in the example, the default system prompt displays, as does the user input command that I'm sending to the shell from the expect script.

Is there a regular expression or something that I can write to prevent the prompt and command that I'm sending from printing to the screen? I know that it should be suppressed if I have an expect command following the Code:

send -s "\nread n_card?'Enter the network interface card number for this server (i.e. eth0):   '\r

command, but everything I have tried for strings and regular expressions to expect causes the netstat -rn output to not show up all of a sudden. I'm new to expect, so I'm not really sure why this is happening.

I would really appreciate any help/suggestions. Thanks for your time!

Part of the Script Code:
Code:

expect {
   -re $prompt {   ;# Send individual commands and get user input
        set timeout -1
        
        # Get partner hostname and put in vipsetup.txt file
        send -s "hostname > vipsetup.txt\r"  
        expect -re $prompt
        
        # Display the network routing info for the user and prompt for 
        # network interface card number
        send -s "print \"The network routing table for the $ptner server is displayed below:\n\" ; netstat -rn \r"
        
        expect -re "\r(.*):\r"
        send -s "\nread n_card?'Enter the network interface card number for this server (i.e. eth0):   '\r"
        interact "\r" return    ;# Wait for user input from read command
        send -- "\r"
        send -s "echo \$n_card >> vipsetup.txt\r"  
        
        # Obtain subnet mask information for partner based on network 
        # interface card number being used
        send -s "msk=\$(cat /etc/sysconfig/network-scripts/ifcfg-\$n_card | grep NETMASK)\r"
        send -s "msk=\$(echo \${msk#NETMASK=})\r"
        send -s "echo \$msk >> vipsetup.txt\r"
    }
    timeout {
        send_user "Connection to host $hostip timed out."
        exit 6 
    }
    eof {
        send_user "Connection to host $hostip failed."
        exit
    }
}

Script Output:
Code:

The network routing table for the PRIMARY server is displayed below:

Apologies. I've been out of Unix for 14 years, and the gears have rusted. Also, Unix has changed - enough similarities to memory that I'm pretty comfy though.

Glad to see lots of info available via google. However changes are going to take getting used to. Have set up a testbed of 3 nearly identical machines, hoping to make an (at home) private network where I can automate installs and set-ups using NIS and NFS (Similar to work I once did).

Have found useful scripts interspersed with comments, would like to copy and paste them to a bash script that:

Reads the line.
Echos the line.
Reads the reply.
Executes what is typed.

Essentially, by making myself type (or copy & paste) the commands I think I'll become familiar.

Figured I'd use a spreadsheet, select the file, and paste into column B of the spreadsheet. In column A I'd paste:

echo "

and in column C I'd paste:

"

Then I'd cut and paste into a text document, insert the lines:

read A
$A

behind every command necessary to the actual task.

Figured I'd have to escape the ' and ".

Ran a test (test.bash):

#!/bin/bash
for i in `seq 1 10`;
do
echo "Enter a command:"
read A
echo "Trying $A"
$A
done

works fine when I type

ls -alg

but not so when I type

ls -alg | grep dwrx

so I'm wondering if someone has a suggestion?

Thanks for any ideas.

Hi All,
Is there a way to mirror plesk mail server with another mail server like primary and secondary. The primary will be in our location with different IP address and the secondary will be with plesk with existing IP address but the domain name should be the same like how gmail has multiple IP addresses on different servers/locations. This is for high availability and to reduce the network bandwidth i.e if any of the server goes down we can still send/receive mails from another and when the server comes online which was offline then all mails should be replicated with each other i.e if primary was down then all new mails should be synced from secondary or if secondary was down then the sync should be from primary. Other thing is since primary will be with us, it will be much faster than secondary(plesk) in sending/receiving the mails. So expecting your kind help about the steps or url links to acheive the same as I don't have much experience on this. The present mail server using qmail on rhel 6.5 64 bit.

I have many hosts as following. But those hosts are dual operating system (Linux and Windows). I always run program background. If someone is using Linux, it is fine. But if someone is using windows or the host is offline. Then, I cannot use ssh. The way I do preiviously is first ssh one by one. And then find the hosts which are offline or windows. And write them down one by one. And then ssh to hosts except them. Let us assume the number of programs is less than the total available hosts. Can someone write a shell script to output the all available hosts to a file like "host_available"?
Here is the host file.
https://www.dropbox.com/s/vbz6w864y3...tlist.txt?dl=0
I am using ssh to connect the computers on campus. If the computer I am trying to connect is offline or using windows, the ssh will take long time, and finally it will failed. I write a shell script to generate the hostlist
Code:

#!/bin/bash
for i in `seq -w 1 28`
do
echo "c15-0330-$i.ad.mtu.edu"
# I would like to add a command here to see whether ssh c15-0330-$i.ad.mtu.edu it succeeds or not. And then output a #file which contains the all available host.
done
for i in `seq -w 1 20`
do
echo "c28-0112-$i.ad.mtu.edu"
done
for i in `seq -w 1 20`
do
echo "c28-112a-$i.ad.mtu.edu"
done

I do not how to set a certain time to see whether connection is successful or not (see the comment in the shell script).
