Hi Todd,
Thank you so much as always.
Actually to run the ansible we switch from normal user to root user and run
the ansible.
In my case when I m running "who am i" from Putty it is working but when I
am executing it from visual studio code using remote ssh login plugin there
it is not working.
Basically I want to send the mail from the user who logged in ex:
[email protected]. Even though we logged in as root when we give "who am i" it
returns the logged in user even though you su to another user. I will try
to use your code. Incase still my approach is bad please let me know.
Ex:
ubuntu /home/gara% who am i
gara pts/0 2008-06-20 11:36 (192.168.0.1)
ubuntu /home/gara% whoami
gara
ubuntu /home/gara% su -
Password:
root@ubuntu:~# who am i
gara pts/0 Jun 20 11:36 (192.168.0.1)
root@ubuntu:~# whoami
root
root@ubuntu:~#
Regarding the mailing function I am using the below. But it takes 10 min to
send the mail.
class Send_Mail:
def __init__(self, to_addrs, workbook_path):
self.to_addrs = to_addrs
self.workbook_path = workbook_path
d = self.workbook_path.rsplit("/", 3)
self.workbook_filename = d[3]
def send_mail(self):
import smtplib
from email.mime.text import MIMEText
from email import encoders
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart
msg = MIMEMultipart()
msg['Subject'] = "Validation Result"
msg["From"] = "[email protected]"
msg["To"] = self.to_addrs
msg.preamble = 'excel test'
try:
file = open(self.workbook_path, 'rb')
attachment = MIMEBase('application', 'vnd.ms-excel')
attachment.set_payload(file.read())
file.close()
encoders.encode_base64(attachment)
attachment.add_header("Content-Disposition", 'attachment',
filename=self.workbook_filename)
msg.attach(MIMEText('Attached is your validation
result.\n\n\n', 'plain'))
msg.attach(attachment)
smtp = smtplib.SMTP('localhost')
smtp.send_message(msg)
smtp.close()
except IOError as e:
print('IOE Exception!!\n{0}'.format(e))
except:
raise RuntimeError("Sorry,email could not be sent successfully."
"Please scp the validation result yourself, "
"there might be something wrong with the
email address or something\n ")
else:
print('Validation result is now being sent as an Excel file to
{0}.'.format(self.to_addrs))
finally:
smtp.close()
file.close()
----
sendmail = Send_Mail(to_addrs, workbook_path)
sendmail.send_mail()
------
Kind regards
