Ubuntu Software RAID & Degraded Disk System Email Warning

Hi,


Need a little help here

I've been setting up a 12.04 fileserver using RAID1. 2 harddisks. After setting it up I made some changes to the configuration using the "dpkg-reconfigure mdadm" command. I was asked if I wanted the "RAID Monitor Deamon...." to notify by email if a disk gets degraded. And this I would really like to. But, what do I need to install/set-up for the system to be able to send such an email???

I guess some kind of mail client/smtp. It's a standard Ubuntu Server 12.04 Fileserver setup!

Looking forward to hear from you

Can't get it to send a mail using Gmail

Hi Srijan,
and others if you can help


I installed msmtp, followed the tutorial and tested the system. First I got an login error because of wrong login/password. This was quickly fixed, but then I still got the error:

msmtp: authentication failed (method PLAIN)

I checked 1000 pages online and have been trying a lot of stuff. But I can't solve the problem. Anybody who can help me here?

Here's the problem:

Hi Srijan,


Well, I succeeded in setting up the system, so that a warning mail from the RAID Monitor Deamon can be sent from the fileserver, if & when a array gets degraded!
But, I still want to be able to sent it using the Gmail SMTP, and this I haven't cracked yet. So please help me with that

Code:

This is an automatically generated mail message from mdadm
running on servername.domain.dk

A DegradedArray event had been detected on md device /dev/md/1.

Faithfully yours, etc.

P.S. The /proc/mdstat file currently contains the following:

Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md1 : active raid1 sda2[0]
      483267392 blocks super 1.2 [2/1] [U_]

md0 : active raid1 sda1[0] sdb1[1]
      1950656 blocks super 1.2 [2/2] [UU]

 

Hi Dan,

Please refer http://basskozz.wordpress.com/2008/...w-email-notifications-via-gmail-the-easy-way/

 

Hi Srijan,


Thanks for helping me

This ToDo is a way to send those system notifications using Exim4. It's not the MTA I need, I allready have MSMTP installed and it works, just not with Gmail.
I described it here: http://www.howtoforge.com/forums/showthread.php?p=317966#post317966

It was what you wanted me to see right? The Exim4 MTA??

Thanks Srijan

 

SOLVED! Gmail settings has to be changed...

Hi,


At last I cracked it... The problem was "modern security systems" for services such as Gmail.

Changing the settings for the Gmail account you want to use, solves the problem

Here's how you do it:

1. Allowing less secure apps to access your Gmail account:
Log in to your Gmail account from your computer, not your smartphone. Goto this url:
https://www.google.com/settings/security/lesssecureapps
and choose "Allow"

Here's some additional information:

Code:

Allowing less secure apps to access your account

Google may block sign in attempts from some apps or devices that do not use modern security standards. Since these apps and devices are easier to break into, blocking them helps keep your account safer.

Some examples of apps that do not support the latest security standards include:

    The Mail app on your iPhone or iPad with iOS 6 or below
    The Mail app on your Windows phone preceding the 8.1 release
    Some Desktop mail clients like Microsoft Outlook and Mozilla Thunderbird

Access your account

To help keep your account secure, we may block these less secure apps from accessing your account, and you’ll see a “Password incorrect” error when trying to sign in. If this is the case, you have two options:

Upgrade to a more secure app that uses the most up to date security measures. All Google products, like Gmail, use the latest security measures.
Go to Allow less secure apps and choose “Allow” to let less secure apps access your Google account. We don't recommend this option because it may make it easier for someone to gain access to your account.

2. Sample of an MSMTP config file. Replace red markins with your own information:
# vi /etc/msmtprc

Code:

defaults
tls on
tls_starttls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt

account default
host smtp.gmail.com
port 587
auth on
user [COLOR="Red"]youremail[/COLOR]@gmail.com
password [COLOR="Red"]******[/COLOR]
from [COLOR="Red"]youremail[/COLOR]@gmail.com
logfile /var/log/msmtp.log

3. Test it using this command line. Replace red markins with your own information:

Code:

# echo -e "Subject: MSMTP Test Mail\r\n\r\nThis is a test e-mail from my server using msmtp" | msmtp --debug --from=default -t [COLOR="Red"]youremail[/COLOR]@gmail.com

That's it! If you have been following this thread, you've seen/followed the same setups/configurations as me and then it'll all work now.
If not, please let me know and then I'll write a ToDO for you You can just post a reply here and I'll see it.

Thanks for the help Mr. Srijan
