With Ubuntu 14 How DO I Get Rid Off The 'Keyring'

I'm running kali linux. I'm having troubles installing pretty much anything, because when I add any ppa using the add-apt-repository command, I get an error message. I'll use simple screen recorder as an example

add-apt-repository ppa:maarten-baert/simplescreenrecorder

maarten-baert/simplescreenrecorder
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.EQM7zzCyye --trustdb-name /etc/apt//trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-jessie-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-jessie-security-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-jessie-stable.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-squeeze-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-squeeze-stable.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-wheezy-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-wheezy-stable.gpg --keyring /etc/apt/trusted.gpg.d//kali-archive-keyring.gpg --keyserver keyserver.ubuntu.com

Can someone please tell me what is going on? I have never been able to add a ppa before using kali linux.

For one user I generated a gpg2 key-pair. I exported these to ascii-armour text files as master.asc and pub.asc. Then took only the pub.asc onto the keyring of a second user on the same partition. I "signed" a simple text file (say trial.txt) with the master key and also transferred it to the home directory of the second user. The pub key on the second user's keyring could verify the signature on the signed text file (trial.txt.gpg) but could not decrypt it. Also, a file encrypted by the second user with the pubkey could be decrypted by the masterkey. Each key therefore has, embedded in its structure, information about child/parent keys. Can anyone thrown light on the actual method of incorporation of this mutual recognition in the key structures? Note:The same kind of recognition happens with sub-keys derived from the Master-key. Can't find any literature which details. Help pl.

HELLO to all,

I am now using an old Acer laptop and I accidentally set the default keyring password a long time ago, and now I don't remember it. Is there a way I can delete the password or better reset it? I also need to say I am currently using CENTOS 6.6 O/S. Hope you can help me.

Thanks for all your help,

Looking at the /etc/shadow file, for some of the system services accounts there are "*" and for others "!!" in the password field.
Searching online I have only found that !=*, i.e. prevent use for log-in, but, if true, what is the actual difference? Why not use "*" on all of them? And why double exclamation point?

I'm trying to send all root's mails to an external e-mailaddress, but for some reason I can't get it to work.

I've edited /etc/aliases with the following rule:

root: <myexternal@email.address>

and run newaliasses after, which would run without any errors.

I can run: echo "Testing" | mail -s "Server Testing" <myexternal@email.address>
just fine without any issue and it's being delivered correctly to my external address.

But when I run: echo "Testing" | mail -s "Server Testing" root

I (first) get a "Deferred: 451 Temporary local problem - please try again later" error and when I then run: "Sendmail -OTimeout.hoststatus=0m -q -v" to flush the mailqueue it says everything is ok, but I then get a message saying I have new mail in /var/spool/mail/root and I don't get the mail on my external e-mailaddress.

I have no clue where to look next, hopefully you guys can point me in the right direction.

Just for completeness: I use mageia release 4 (x86_x64).

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.

I use following shell script to send email. But the subject of email always shows "This" instead of "This is L_1.R is finished". You may refer http://www.linuxquestions.org/questions/linux-newbie-8/how-to-define-variable-in-%60ssh%60-4175540566/
Code:

host_list=("c15-0330-01.ad.mtu.edu" "c15-0330-02.ad.mtu.edu" "c15-0330-03.ad.mtu.edu" "c15-0330-04.ad.mtu.edu")
program=("L_1" "L_2" "L_3" "L_4")
subject="The job is finished"
ssh -f c15-0330-01.ad.mtu.edu 'echo' "the job ${program[0]} is finished" '|' 'mutt "zwang10@mtu.edu" -s' "This is "${program[0]}".R is finished";

Hi!

Here is mine configuration and I want make it show unicode(russian) in console, it works perfect in X11 but not when I logging into tty.

vconsole.conf
Code:

LOCALE="en_US.UTF-8"
KEYMAP="sv-latin1"
FONT_UNIMAP="lat1"
FONT_MAP="ISO8859-1"
CONSOLEFONT="ruscii_8x8"
HARDWARECLOCK="localtime"
TIMEZONE="Europe/Stockholm"
USECOLOR="yes"

I need to execute this .bashrc string:

alias lml='grep '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}' mail.log | grep "relay=" | awk '{print $8}'' #list mail log

I have tried enclosing the string in alias as lml="..." and alias lml=`...` to no avail. The problem is apparently with the grep "relay=" in that it has to be enclosed in "", as well as the awk that has to be enclosed in ''.

Any ideas on how to get this setup? Thanks.

I just installed Redhat 7 and try to config the network , add the IP address to network card , but I got the problem.

I modify the file /etc/sysconfig/network-scripts/ifcfg-enp0s3 , the configuration is as below , and then reboot .

DEVICE="enp0s3"
NETBOOT="yes"
HWADDR="08:00:27:15:38:B7"
TYPE="Ethernet"
BOOTPROTO="none"
NAME="enp0s3"
UUID="462f4834-4fe7-43a7-84e7-83b2722e94c1"
ONBOOT="yes"
IPADDR="192.168.1.1"
NETMASK="255.255.255.0"

After reboot , I use "ip addr show" still not shown the ip address , the ip address is still blank , would advise what is wrong ? thanks
