ubuntuda windows alanı mount etme (mounting windows share on ubuntu )

öncelikle cifs ' i yükleyeceğiz

# sudo apt-get install cifs-utils


 linuxde id komutu ile group ve user id kodunu bulun(büyük ihtimal ikisi de 1000 dir)

#id


şimdi mount komutunu çalıştırabiliriz.

# sudo mount //WINSRV/SHARE -t cifs -o uid=1000,gid=1000,username=winuser /mnt/path

örnek:
#sudo mount //10.1.2.3/share -t cifs -o uid=1000,gid=1000,username=IBRAHIMPEKTAS,domain=BIM  /mnt/share
 bu kadar

Send mails from command line

Install the mailx command

On Ubuntu/Debian based systems the mailx command is available from 2 different packages -
1. heirloom-mailx
2. bsd-mailx
We shall be using the heirloom-mailx package because it has more features and options.
On CentOS/Fedora based systems, there is only one package named "mailx" which is the heirloom package.
To find out what mailx package is installed on your system, check the "man mailx" output and scroll down to the end and you should see some useful information.

# ubuntu/debian
$ sudo apt-get install heirloom-mailx

# fedora/centos
$ sudo yum install mailx

Using the mailx command

Once installed, the mailx command can be directly referenced with the name mail, so you just type in that in the command line.

1. Simple mail

Run the following command, and then mailx would wait for you to enter the message of the email. You can hit enter for new lines. When done typing the message, press Ctrl+D and mailx would display EOT.
After than mailx automatically delivers the email to the destination.

$ mail -s "This is the subject" someone@example.com
Hi someone
How are you
I am fine
Bye
EOT

2. Take message from a file

The message body of the email can be taken from a file as well.

$ mail -s "This is Subject" someone@example.com < /path/to/file

The message can also be piped using the echo command -

$ echo "This is message body" | mail -s "This is Subject" someone@example.com

3. Multiple recipients

To send the mail to multiple recipients, specify all the emails separated by a comma

$ echo "This is message body" | mail -s "This is Subject" someone@example.com,someone2@example.com

4. CC and BCC

The "-c" and "-b" options can be used to add CC and BCC addresses respectively.

$ echo "This is message body" | mail -s "This is Subject" -c ccuser@example.com someone@example.com

5. Specify From name and address

To specify a "FROM" name and address, use the "-r" option. The name should be followed by the address wrapped in "<>".

$ echo "This is message body" | mail -s "This is Subject" -r "Harry" someone@example.com

6. Specify "Reply-To" address

The reply to address is set with the internal option variable "replyto" using the "-S" option.

# replyto email
$ echo "This is message" | mail -s "Testing replyto" -S replyto="mark@gmail.com" someone@example.com

# replyto email with a name
$ echo "This is message" | mail -s "Testing replyto" -S replyto="Mark" someone@example.com

7. Attachments

Attachments can be added with the "-a" option.

$ echo "This is message body" | mail -s "This is Subject" -r "Harry" -a /path/to/file someone@example.com

8. Use external SMTP server

This is an exclusive feature, that you get only with heirloom mailx and not bsd mailx, or the mail command from gnu mailutils or the mutt command.
The mailx command can use an external smtp server to use to relay the message forward. The syntax is a bit lengthy but makes sense.

$ echo "This is the message body and contains the message" | mailx -v -r "someone@example.com" -s "This is the subject" -S smtp="mail.example.com:587" -S smtp-use-starttls -S smtp-auth=login -S smtp-auth-user="someone@example.com" -S smtp-auth-password="abc123" -S ssl-verify=ignore yourfriend@gmail.com

Here is a breakdown

$ echo "This is the message body and contains the message" | mailx -v \
> -r "someone@example.com" \
> -s "This is the subject" \
> -S smtp="mail.example.com:587" \
> -S smtp-use-starttls \
> -S smtp-auth=login \
> -S smtp-auth-user="someone@example.com" \
> -S smtp-auth-password="abc123" \
> -S ssl-verify=ignore \
> yourfriend@gmail.com

You can use the gmail smtp servers and send emails via your gmail account. That is so cool!

9. Verbose - watch smtp communication

When using external smtp servers, you can choose to watch the entire smtp communication that is done in the background. This is useful specially when testing or debugging smtp servers.

$ echo "This is the message body and contains the message from heirloom mailx" | mailx -v -s "This is the subject" -S smtp="smtp.gmail.com:587" -S smtp-use-starttls -S smtp-auth=login -S smtp-auth-user="mygmail@gmail.com" -S smtp-auth-password="mypassword" -S ssl-verify=ignore someone@example.com

Troubleshooting

In case the mails are not being delivered properly you need to check a few things. The first thing to check is that an smtp server (mta) is running locally. The netstat command can tell that

$ sudo netstat -ltnp | grep 25
[sudo] password for enlightened: 
tcp        0      0 0.0.0.0:25              0.0.0.0:*               LISTEN      2541/master     
tcp6       0      0 :::25                   :::*                    LISTEN      2541/master

If an stmp server like Postfix is running and still mails are not going, then try re-configuring Postfix for example. On Ubuntu/Debian systems, this can be done with the dpkg-reconfigure command

$ sudo dpkg-reconfigure postfix

Then retry, the mail command and it should work. If it still doesn't, try contacting your server provider.

Remote desktop Sharing in Ubuntu 14.04

Ubuntu 14.04 te aşağıdaki gibi vnc-viewer hatası alıyorsanız;  Vino require-encryption false yapmanız gerekebilir.

java.io.IOException: No security type suitable for RFB 3.3 supported

 you must to do step step in below

$ pkill vino
$ export DISPLAY=:0.0
$ /usr/lib/vino/vino-server &

still not working
after short investigation:

gsettings set org.gnome.Vino require-encryption false

now it`s work but i need it permanently  :))

Looks like something wrong with default gui Lets install something else like dconf



sudo apt-get install dconf-tools
finally: dconf > desktop > gnome > remote-access > enabled - uncheck !!!
issue fixed.

Maybe i use not correct way but to somebody it`s can be useful.:)
