General Help & Advice / Identifying an Asus board
« on: July 12, 2020, 08:37:59 pm »
An elderly friend has an old Asus that I gave her ages ago.  It's a P6 P5G41 E with the PN5-E mother-board.  Can anyone tell me if it's 32 or 64 bit?  I have the manual but, bizarrely, it doesn't tell me! 
As she lives 120 miles away I don't want to pick it up for repair if it's only 32-bit - I'll give her another. 

Thanks

General Discussion / Covid-19, contact tracing and privacy
« on: June 26, 2020, 08:20:54 am »
I came across a couple of web pages that are relevant to our lock-down status and might be of interest to Forum readers.
The privacy issues of contact-tracing applications may account for the poor take-up of mobile 'phone "apps", and with good reason. Here are the links:
1. https://protonmail.com/blog/privacy-contact-tracing-apps/?utm_campaign=ww-en-2c-mail-coms_con-monthly_newsletter&utm_source=proton_users&utm_medium=link&utm_content=2020_june&utm_term=mail
2. https://ncase.me/contact-tracing/

By the way:  ProtonMail offers free and very secure mail and VPN services, and their customer care is first class even for non-paying users.  [I have no commercial interest in ProtonMail]

General Help & Advice / Sendmail problems
« on: February 12, 2020, 06:23:16 pm »
Lenovo Thinkpad T500 - Ubuntu 16.04

Since my email provider has updated its security arrangements it can’t accept my emails sent from  the command line with a sender name that is not my registered username – e.g. an alias.  This ought not be a problem as I have set up my /etc/ssmtp/ssmtp.conf file with my registered base address that ought to be used by sendmail:

ssmtp.conf
root=[email protected]
mailhub=mail.runbox.com:465

AuthUser=[email protected]
AuthPass={password}
UseTLS=YES
UseSSL=YES

rewriteDomain=mailco.com
hostname=T500
FromLineOverride=YES
--------------------------------------------------

But when I use sendmail, it removes my surname from the “From” address and my mail provider rejects the email as the From name is incorrect:

[email protected]:~/.bin$ sendmail -v [email protected]  < mail_message
[<-] 220 mailfront20.runbox ESMTP Exim 4.90_1 Ubuntu Wed, 12 Feb 2020 18:55:02 +0100

In principle I could add the name "[email protected]" to my account as an alias and that would work, but someone has already claimed that so I can't use it.
My mail provider has been unable to help me and I would be grateful for advice.

General Help & Advice / mpack & sendmail problems
« on: January 05, 2020, 03:48:44 pm »
I wrote a script ages ago that sends me an email automatically when some function is satisfied.  It has worked well but failed recently, with a message appended suggesting that I visit my mail provider’s website that explains the problem.
Although my application uses mpack, I show below an example using sendmail to demonstrate the problem.  I’ve changed my email address and mail provider for security, but keeping the same formats. 

Terminal command

[email protected]:~$ echo "Subject: sendmail test" | sendmail -v [email protected]mailco.com
[<-] 220 mailfront20.emailco ESMTP Exim 4.90_1 Ubuntu Wed, 01 Jan 2020 17:06:01 +0100

sendmail: 550 Invalid From address. Please see https://help.emailco.com/identities/
[email protected]:~$

You will see at the end the complaint that the From address is wrong and is rejected by my mail company following their updated security measures.  The correct address is shown on the “RCPT TO:” line but in the active line where the correct address needs to be the address has been shortened:  “MAIL FROM: <[email protected]>”.   And perhaps the other "From" line needs to be correct as well.

My email provider now requires that the from address is not an alias and the sSMTP.conf file (shown below) shows my base address correctly (as it always was).  I have even tried changing the Thunderbird default address back to the base address.  So I can’t understand why it has been changed in two places in sendmail.   

Contents of  etc/ssmtp/ssmtp.conf

# Config file for sSMTP sendmail
#
# The person who gets all mail for userids < 1000
# Make this empty to disable rewriting.
#root=postmaster
[email protected]

# The place where the mail goes. The actual machine name is required no
# MX records are consulted. Commonly mailhosts are named mail.domain.com
#mailhub=mail
mailhub=mail.emailco.com:465

UseTLS=YES
UseSSL=YES

# Where will the mail seem to come from?
#rewriteDomain=
rewriteDomain=emailco.com

# The full hostname

hostname=T500

# Are users allowed to set their own From: address?
# YES - Allow the user to specify their own From: address
# NO - Use the system generated From: address
FromLineOverride=YES


I would be very grateful for any advice.

Ubuntu / Using "mpack" to send files [SOLVED]
« on: July 25, 2019, 08:52:44 pm »
I use mpack on my T500 laptop, after a lot of initial difficulty, and now want to use it on an ASUSTeK P6-P5G41E running Ubuntu 18.04 in gnome-flashback.

The command format is mpack -s "<subject line>"  -a <file path>  <email address>   which works fine on my T500 but on the Asus the error message is "execv: No such file or directory"  although the specified file-path is valid. 

Any ideas would be welcome.
----------------
[EDIT]  It turns out that the Mail Transfer Agent "sendmail" was not installed by default.  Installing it removes the error message but the email is still not sent.
[EDIT2] Remembered that I need to set up a ssmtp.conf file in /etc/ssmtp so copied the file from my T500 and edited it for the owner of the Asus.  Still no joy.
[EDIT 3] It turns out that SSMTP was not installed despite Thunderbird working well.  Installing it makes mpack work OK. 

SOLUTION:
Install sendmail
Install SSMTP
Create a file /etc/ssmtp/ssmtp.conf
  See the second link below.

Ubuntu / Ubuntu 18: Lost icons in top right of Classic View [SOLVED]
« on: July 23, 2019, 07:00:33 pm »
ASUSTeK P6-P5G41E running Ubuntu 18.04 in gnome-flashback

I thought I was removing just one icon from the top right panel but they all disappeared! 
I've done this before (sorry!) but can't remember how to recover them, and my web search wasn't helpful.

I would be grateful for advice.
Thanks

[EDIT] Tried dconf reset -f /org/gnome/gnome-panel/ without success.

[EDIT 2] Tried:
sudo apt-get update
killall gnome-panel
sudo apt-get install --reinstall gnome-panel gnome-applets
sudo apt-get -f install


...after this, ALL the top panels disappeared but a reboot restored them.  Success!

Internet Connectivity / No wireless with Mint 18 [SOLVED!]
« on: July 23, 2019, 09:13:21 am »
I have installed Mint 18 on a friend’s Dell Inspiron 1501 laptop.  Unfortunately, the built-in wifi doesn’t work with this installation although a USB wifi dongle works well (so I know that the network is set up correctly) as does Ethernet. 

Wifi enabled in BIOS and the network info entered. 
Keyboard Fn F2 to toggle wifi has no effect.
Here is some output that might help diagnosis:

[email protected] ~ $ rfkill list all
[email protected] ~ $ iwconfig
lo        no wireless extensions.
eth0      no wireless extensions.

I’ve installed  b43-fwcutter and firmware-b43-installer
I am guessing that the installer installs the b43-fwcutter but I don’t know how to use it.
I did find an example of the use of b43-fwcutter:    b43-fwcutter -w /lib/firmware wl_apsta.o
but I’m not confident about just copying this as it might not be appropriate for this machine. 
Can anyone advise me on the the best way forward?

Thank you

Hardware Compatibility / usb wireless adapter for Ubuntu18.04
« on: July 11, 2019, 10:36:46 pm »
I am preparing an ASUSTeK P6-P5G41E desktop running Ubuntu 18.04 to give to a friend.  Having fitted a 256GB SSD (thanks, Mark) it's working much faster I want now to find a suitable USB wireless dongle for it. 
I bought one from Amazon that mentioned Linux suitability but Ubuntu 18 ignored it.  So I tried to install the accompanying drivers from the CD but the PC refused to extract the files, telling me that I didn't have sufficient privileges!  So I sent it back. 
I have a very old Belkin 802.11g adapter so tried that and it connected immediately - which makes it a valuable item that I want to keep! 

Bizarrely, I can actually still buy the Belkin 802.11g from Amazon, which I might do, but a more modern one that works out of the box would be better. 
I see lots of questions on the forums about getting dongles to work with Ubuntu 18 and would be grateful for advice from anyone on a device that will work on U18 without having to install anything. 

Thanks

Ubuntu / Network manager icon missing in Ubuntu 18.04
« on: July 11, 2019, 01:24:16 pm »
ASUSTeK P6-P5G41E running Ubuntu 18.04

This machine doesn’t have a wireless card so before donating it I bought a USB wireless adapter (Bonest USB 3.0 ) as it mentioned Linux in the blurb.  I ignored the installation disk and plugged it in with no response from the system, which surprised me.  Indeed, the network manager told me that no dongle was detected.
Next I tried installing the Linux software from the disk but the extract command resulted in a message that I didn’t have sufficient privileges to do the extraction.  So I abandoned that to return the dongle to Amazon. 
At this point I noticed that the wireless manager icon had disappeared from the tray at top right.  Hmm!  I plugged in a very old, spare USB wireless adapter which connected me immediately, but still no icon. 
Looking on-line for possible solutions, I tried the following with no success:

[email protected]:~$ sudo service network-manager stop
[email protected]:~$ sudo rm /var/lib/NetworkManager/NetworkManager.state
[email protected]:~$ sudo service network-manager start
[email protected]:~$

[email protected]:~$ killall unity-panel-service
unity-panel-service: no process found
[email protected]:~$

[email protected]:~$ sudo apt-get install indicator-applet-complete
   Reading package lists... Done
   Building dependency tree       
   Reading state information... Done
   indicator-applet-complete is already the newest version (12.10.2+17.10.20170425-   0ubuntu1).
   indicator-applet-complete set to manually installed.
   0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
[email protected]:~$

[email protected]:~$ sudo apt-get install --reinstall network-manager network-manager-gnome
[email protected]:~$

Not having the icon is no real problem as I can always get to the network manager via the menus but it’s a nuisance if I am giving the machine to a friend and I would be grateful for advice.

General Help & Advice / Formatting an SSD for system use
« on: July 08, 2019, 03:45:33 pm »
I bought a very cheap Asus with Mint on it and when visiting my local PC emporium I got the chap to swap the HDD for a 256GB SSD.  He checked out the system with windows (he’s a Windows only man).  Months later I get back to the Asus for the first time and it won’t let me boot a Live USB (despite changing the boot priority) and demanded that I register Windows. 

I extracted the device to a carrier and plugged it into a USB port on my Lenovo T500 laptop.  The response was:
Unable to mount 255 GB Volume
Error mounting /dev/sdb2 at /media/keith/FA24921C2491DC47: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000" "/dev/sdb2" "/media/keith/FA24921C2491DC47"' exited with non-zero exit status 14: Windows is hibernated, refused to mount.
Failed to mount '/dev/sdb2': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option.

Not understanding all this and impetuous as ever I decided to reformat it, not thinking that I would need a boot sector, etc.  So I now have a single Ext4 partition on it.  Plugging it back into the ASUS I tried to boot from an Ubuntu 18 live USB but the system just hung with a black screen. 

I’ve looked on line for how to partition the SSD but the instructions imply some knowledge that I don’t have. 
I’ve been very foolish but would be grateful for help in formatting it correctly (in a carrier USB’d to my Laptop) so that I can return it to the ASUS and Install Ubuntu 18. 

[Laptop:  Lenovo T500 64 bit and Ubuntu 16.04]

Programming / Using the "du" command with a file-list [SOLVED]
« on: March 27, 2019, 09:11:31 pm »
As part of a backup script I want to find the total GB of a list of files to be backed up to see if the supplied USB stick is big enough.
The ideal command is du, for example:
[email protected]:~$ du -sch Documents Desktop Pictures
2.4G   Documents
73M   Desktop
1.9G   Pictures
4.4G   total
[email protected]:~$

Better still, du has an option to read the file list from a file:
--files0-from=<file-list-path>
but the listed file/directory names must be NUL-terminated, and this is where I have become stuck.

A web search indicates "\0" as a null character but adding printf "\0" after a name when creating the file-list does  not work, and I've tried many other variations offered on the web. 
I would be grateful if anyone can suggest a way of listing files/directories in a file so that du will read it.

Hardware Compatibility / USBs and DVDs not working [ABANDONED]
« on: March 12, 2019, 01:08:12 pm »
I have an old desktop with an ASUS A7N8X motherboard to be renovated for a friend. 
It has XP loaded and is unbelievably slow.  At first I thought the slowness might be partly due to the age of the motherboard but the spec doesn't look too bad - although I might change the board for something better if she can afford it. 

The immediate problem is that I can't run a Linux Live USB or DVD as neither the DVD drives nor the USB sockets respond to any device.  I've tried setting the boot preferences to anything that seemed reasonable but it always boots into XP although the boot process indicates that it is booting from (for example) the DVD. 

I've checked the leads from the USBs and DVDs to the motherboard and all are placed securely in the right positions. 
The PS2 keyboard works but I don't have a PS2 mouse - I can use my USB mouse if I can get the Live USB/DVD working. 

Any advice for getting a Live USB/DVD working would be very welcome.
Thank you.
