Re: debian-user-digest Digest V2020 #932




Re: Mail transfer agent 

Sorry for breaking the chain.
Yahoo mail doesn't handle lists well and every time I tried trimming the excess Yahoo threw the message in the trash.
Trying to get mutt to send mail I've got this in .muttrc:

set smtp_pass="myPasswd"
# set smtp_url="smtp[s]://[user[:pass]@]host[:port]"
# set smtp_url="smtp://mikemcclain46:myPasswd@suddenlink.net:587"
set smtp_url="smtp://mikemcclain46:myPasswd@suddenlink.net:587/"
# set smtp_url="smtp://mikemcclain46:myPasswd@suddenlink.net:465/"
# set smtp_url="smtp://mikemcclain46:myPasswd@suddenlink.net:465"
#smtp.suddenlink.net::587
#smtp_url="smtp://loginname@smtp.server.net:587/"
set smtp_authenticators="plain"
# set smtp_authenticators=
set envelope_from_address="mikemcclain46@suddenlink.net"
set use_envelope_from

The commented lines above are things I tried that didn't work.

This is a line from /etc/exim4/update-exim4.conf.conf that worked when I had exim4 installed:
dc_smarthost='smtp.suddenlink.net::587'

/etc/mailname says this:
mikemcclain.46@suddenlink.net

trying to send mail via mutt:
    Could not connect to suddenlink.net (Interrupted system call).

Thinking postfix might be messing things up I deleted it.
That made no difference so I installed dma, still no outgoing mail, deleted.

What am I missing?

Thanks,
Mike

The code for CRC is so small and simple that virtually all applications
choose to implement it directly, rather than use a library or an
external application for it.

Also, note, there is no single `crc` (unlike MD5 or sha128). Strictly
speaking, Cyclic Redundancy Code is an algorithm, and you need to
specify more parameters (bit-width, polynom, initial value, and more) to
be able to actually implement it in code.
Sometimes people also say CRC when it is unambiguous in a certain field,
like CRC-32 for ethernet frames).

I'm not sure I understand this question or how it relates to the
previous one.

How are you "looking at" the file?  I would suggest using less.

You get out of less by pressing q.

I take it you mean, *new* available packages. I don't know how Ubuntu
does it, so I'll tell you what I do. And the answer depends on what you
want to do.

You could install unattended-upgrades, and let that notify you (via
email) of packages it has already upgraded for you and the occasional
reboot required.

If that's a bit too trusting, set a cron job to pull in new packages,
but not install them. I use:

  5      3      *                *    *    root    sleep $( echo $((1 + RANDOM \% 1=
200)) ) ; /usr/bin/apt-get update > /dev/null && /usr/bin/apt-get -dy dist-=
upgrade > /dev/null

The sleep command waits for up to 1200 seconds. That is there because I
have a small herd of computers here and way back when I was on dial-up
I did not want to swamp my connection.

The apt-get update does an update, and throws away the output.

Same with the dist-upgrade. The -d does a download only.

You could follow that with "apt list --upgradable -a" so cron will
email you a list of available upgrades. Or you could run that manually
when you are ready. I just run "apt upgrade" when I am ready. As I
mentioned, I have a small herd of computers. I run a shell script based
on mssh to check all of them for updates.

If you know what you are looking for in the file, you could use awk,
grep, sed or whatever you want.

Tail, cat, tac are also an options.


In other words, we need to know what you want to be able to provide you
with a command.

RANDOM is a bashism, not available in sh, so that won't work in a
crontab unless you've altered which shell cron is using to parse the
crontab.

If you *do* use bash to parse the line, then the $( echo ... ) bit is
unnecessary.

sleep $((1 + RANDOM \% 1200))

But the safer way is simply to assume that the crontab is being parsed by
sh (because that's what is actually used by default), and move your
bash-specific code to a script.  Then call the script from the crontab.

You must got the correct rights. Either you start plasma as root, then you can 
just start kwrite and open the log file. or, ifr you start plasma as normal 
user, do this:


Start a konsole (like xterm, konsole, uxterm)

then type in "su -p" (without quotes) and enter the password of root. 

and last start "kwrite" in this konsole

Now you can open your logfile.

If you are using another window-manager like GNOME, LXDE, Enligtenment 
whatever, it might got another graphical editor.

Note: Every graphical application can be started with higher rights from the 
konsole (or terminal, how others may call it), by getting higher rights with 
su -p.  (the -p stands for "preserve actual environment).

Good luck

Well, that's interesting. The file I pulled that from (in /etc/cron.d)
sets two variables explicitly:

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

And the machine that it runs on shows:

In dash, RANDOM does nothing; it's just an empty variable.  And as it
turns out, dash treats that as a zero.

unicorn:~$ dash
$ echo $((1 + RANDOM % 1200))
1
$ echo $((1 + % 1200))
dash: 2: arithmetic expression: expecting primary: "1 + % 1200"
$ echo $((1 + XYZZY % 1200))
1

So you're just doing "sleep 1" every time.

Ah, thank you. Yup. Which is weird, because it worked when I first
wrote that many years ago. I may or may not remove that part of the
line. But I will move toward more use of unattended-upgrades, which
handles the original problem differently.

"Many years ago", sh was probably a link to bash, rather than dash.

I thought that's what fetchmail did, and what mutt can do,
the difference being that fetchmail would put them onto your
system while you slept, whereas mutt would fetch them on demand.

I covered that in my previous post.

dma might be enough for doing that.

I use mailx (in mailutils), but mutt can also do it.

Size or complexity? The size of the binary is comparable with mutt.
Granted, there's more documentation, but one barely need touch it
for the above.

How do I get the deb files in order to install locally (via dpkg
--install) the necessary utilities to run CRC32 and/or CRC64

Thank you,
