Sounds right.  I haven't explored their interface for ages, to see
where they hid everything.

That's another bugbear with webmail interfaces; they keep redesigning
things on you, then you have to go hunting for something you need. 
Sure, mail clients do that, too, but far less often (in my experience),
and usually their interfaces seem more logically organised.

Of the few folders mine does store locally, it's in maildir.  I don't
know if that's user-selectable, though.  The preferences window even
says it's maildir for the default "on this computer" folder, but that
folder's not editable (there's only an enable/disable entire folder
option for it).

I suspect though, that internally it sticks with maildir for storing
any mail it's fetched itself.  All the local mail folders I see in
~/.local/share/evolution/mail/ are maildir.

Maildir is a later improvement on MH (according to other authors), so
I'll take their word on that and not debate it, but it's a similar
scheme of individual files for each message, though without an index
file.

You can create non-network accounts where it'll read mail files that
are already on the drive (something else will have to bring them onto
the computer), and then you have a choice of local delivery (no clues
in the preferences interface as to what it reads), MH format, maildir
format, standard Unix mbox spool directory, and standard Unix mbox
spool file.

I seem to recall importing old mail spool files into Evolution, years
ago, simply by dragging and dropping a spool file onto a mail folder
inside Evolution's window, and it automatically handled parsing it. 
I'm fairly sure that was how I finally moved my old mailspool files
from the old Dovecot mail server into the new Dovecot server using
maildir.  Every mail moving tool I'd looked at seemed to require a
computing degree to understand how to drive it.

For my mail it accesses through my IMAP server, it doesn't appear to be
caching them anywhere that I can see (and I've not asked it to).

Seeing how you mentioned satellite internet, that's one of the laggiest
systems and you probably are best off pre-fetching all your mail as a
batch, whatever protocol you use.  Then you're just stepping through
your local cache as you read them.

I don't know about other countries, but it's actually illegal to send
harassing mail, there's nothing that excludes email from that law. 
Mind you, unless it was death threats you're unlikely to get anyone to
take action on it.

I just decided that I'd had enough of it, and wasn't going to deal with
any more.  People can contact me off-list, but either they mention it
on-list and I reply (if I want to), or they do some sleuthing to figure
out how to contact me.

But it's not just harassing mail, some people are just plain nuts and
you can do without having to deal with the weirder stuff they talk
about when they're not in the public eye.  Many years ago I responded
back to a mailing list to a stupid private email, just so everyone
could see what they were like.

Over time there's been discussions about that, but consensus was that
you can't.  Attempting to do so my throttle it somewhat, but not
completely disable it.

While it makes sense to have it detect mail from false addresses and
spam-bin them, it's overzealous and fallible at coming to that
conclusion.  There's a lot of genuine mail that doesn't meet their
criteria for authenticated.

List mail often confused it, and there's a plethora of service
providers that don't authenticate their user's mail as being verified. 
When you send through a SMTP server that requires you to log in, and
you're a customer that somehow they've previously verified your
identity, they should be flagging the mail as it goes through in a way
that other servers trust.  Not all do.  And, of course the spam houses
will fake that trust, anyway, for their own posts.

I had tried that kind of thing before, but other non-user-
controllable anti-spam filters were in effect *before* user
customisable ones.

While that may have changed, I kind of doubt it.

Re: Did firewall logging got broken with netfilter?

My attention span was not sufficient for that one.

The author says he used logs to work out the details, but doesn't says how  
the logs were

obtained.   There is lots of old stuff on netfilter logging:


https://wiki.nftables.org/wiki- 
nftables/index.php/Logging_traffic>Logging traffic - nftables wiki (from  
2017) uses ulogd.


So, there is a logging facility, of some sorts, in nft.

But I already had logging working when firewalld was using iptables. The  
rich rule that specifies logging is still there. Nothing happened to it.


firewall-config even shows this rule. firewall-config has a checkbox to,  
allegedly, enable logging. When showing this rule firewall-config even  
shows this checkbox as selected. So far so good, but the forward march of  
progress ends abruptly, at this point:


No logging.

Also, curiously, I don't seem to be able to edit this rule in firewall- 
config. It shows it but won't let me edit it. The rich rule was added  
directly via firewall-cmd, so at some level firewalld knows about it. Except  
that it is not fully implemented in the UI, and fully unimplemented in the  
netfilter backend. At least the rule itself is there, and its core  
functionality is there. But the logging is sorely missed.


Perusing the nftables wiki it does seem that firewalld /should/ be able to  
grok this, and it's simply not implemented. I'll just cross my fingers, and  
patiently wait for it to catch up with iptables.


A shot in the dark: the old iptables-based rule specified a rate limit on  
the logging. The nft wiki page makes no mention of rate limit. I wonder if  
that's the firewalld limitation, it just ignores the log spefication because  
of that?

dig 1.1.1.1 doesn't return the host name:


You can see running dig followed by an IP doesn't return anything, to do a
reverse DNS lookup, or to resolve the hostname from the IP, you can see in
the second example dig -x followed by the IP returns the hostname
one.one.one.one.

Might you be using systemd-resolved on the f34 to cache for you?

In Fedora 33 DNS resolution was changed (1)adding a DNS server to 
/etc/resolv.conf using systemd-resolve.


There is still an /etc/resolv.conf and it is configured to use a name 
service running on a loopback device where a local DNS service is 
listening.


# grep -v '#' /etc/resolv.conf

nameserver 127.0.0.53
options edns0 trust-ad
search domain.com 


If you are using the NetworkManager service just add the DNS server 
address and it should start working.


The entry for the network device includes the DNS server address



Something like this "nmcli con mod $connectionName ipv4.dns "1.1.1.1 
9.9.9.9".



I tried this, but reverse lookup still doesn't work.

In Fedora 33 DNS resolution was changed (1)adding a DNS server to
/etc/resolv.conf using systemd-resolve.

There is still an /etc/resolv.conf and it is configured to use a name
service running on a loopback device where a local DNS service is listening.

# grep -v '#' /etc/resolv.conf

nameserver 127.0.0.53
options edns0 trust-ad
search domain.com


If you are using the NetworkManager service just add the DNS server address
and it should start working.

Something like this "nmcli con mod $connectionName ipv4.dns "1.1.1.1
9.9.9.9".


At first I didn't like this new way to manage DNS, but I am finding some of
the features to work very well. Like the split dns feature is working
really well with the multiple vpn clients run simultaneously, no more
hacking on /etc/resolv.conf each time a new VPN is started, it just works.

I would check what is in /etc/resolv.conf for both machines.
Do you have any dns caching on any of the hosts?

If you can repro at will next I would use wireshark to see what is send for the 
look ups.

dns lookup behavior

[Paolo Galtieri]

Folks,
 I have 3 Linux systems, one running F31 and 2 running F34.  On one of 
the F34 systems I have a local DNS server running.  This has worked fine 
in the past, but now I'm seeing strangeness on the 2 F34 systems.


I added a host to the DNS server for normal lookup and reverse lookup.  
On the F31 system both:


host centos8-opstcore-vm.homenet172-16-96.com

and

host 172.16.96.20

work. The first returns 172.16.96.20 and the second returns 
centos8-opstcore-vm.homenet172-16-96.com.


On the F34 which is the DNS server the first works, but the second fails 
with:


Host 20.96.16.172.in-addr.arpa. not found: 3(NXDOMAIN)

On the other F34 system I get:

host 172.16.96.20

;; connection timed out; no servers could be reached

The interface has the DNS server pointing to the correct system. If I run:

nslookup
> server 192.168.10.66
Default server: 192.168.10.66
Address: 192.168.10.66#53
> 172.16.96.20
20.96.16.172.in-addr.arpa    name = 
centos8-opstcore-vm.homenet172-16-96.com.

>

Then it works.

What do I need to do on F34 systems to get DNS lookups working?

Any help is appreciated.

Paolo

Hi Roger.
I'm on a Dell XPS 9550, Intel® Core™ i7-6700HQ.
I have the Dell Wireless 1830. and lspci outputs : Broadcom Inc. and 
subsidiaries BCM43602 802.11ac Wireless
https://www.parts-people.com/index.php?action=item&id=21150
Looking at this site suggests my card is effectively an NGFF M2 A/E. 
https://es.aliexpress.com/item/32792644213.html?gatewayAdapt=glo2esp

This laptop also shipped with 2 other options of cards:
The Intel Wireless 7260 and the Killer Wireless N1535 
(https://www.parts-people.com/index.php?action=category&id=143&subid=560&refine=wireless),
 so those would be a sure bet.

Are you suggesting I get the AX200? Any other suggestions?
I'm not looking to get the most powerful card on the market, just something 
decent that is a bit more up to date. Maybe something refurbished I can find on 
parts-people.com ?

thanks again.

Re: how to test Wireless/Bluetooth card on Fedora

[Roger Heflin]

The AX200 card is a Form Factors: NGFF M2 2230 A/E key, so if your
current card is a M2 2230 A or E key then the card should fit, and
will very likely work.

What kind of laptop is it and what intel cpu and chipset does it have?
 And what is the model of the current wifi card?

Thanks for the quick response Samuel. 
I believe the issues I'm having are much worse than normal. If all Bluetooth 
mice behave this way, no one would buy one. I will consider buying one of those 
adapters, I think it could come in handy.

There is an Intel alternative that was an option that came with my laptop 
(Intel Wireless 7260).
I have the Broadcom alternative.
I just don't know how to find out what card I could get that is compatible with 
my laptop. The aforementioned Intel card, I guess, would not be a newer 
generation than the one I already have; since it was offered originally with 
this pc.
thanks very much for this info.

The author says he used logs to work out the details, but doesn't says how
the logs were
obtained.   There is lots of old stuff on netfilter logging:

Logging traffic - nftables wiki
 (from
2017) uses ulogd.

A lucky Google hit has led me to a cure, which is to create
/etc/udev/rules.d/50-usb_power_save.rules. This disables power saving
to the bluetooth dongle. Read:
   
https://askubuntu.com/questions/1303731/how-to-change-bluetooth-timeout-settings-for-bluetooth-mouse
to find the magic and also links to explanations.

started appearing in my terminal when running dnf. That's why
I looked up how to make it stop.

Many of these have low barriers for someone who wants to create a package.
 Some packages
may only be useful for a few users, and those users may all be using
different platforms.   Some
very small fraction of those packages may go on to become widely used.
 Open source makes it
easy for people to innovate, and we need to encourage experimentation, but
we can't have
experiments in linux distros.

In my field, NASA provides a large "mission critical" application which
includes a private tree of
third-party libraries.   The same libraries are available from linux
distros, but many have optional
configurations which differ across linux distros, so bundling the libraries
is a big step towards
ensuring everyone gets a working configuration.   I think other large
commercial packages
(Matlab, IDL) also bundle third-party libraries.

CPAN, CTAN, CRAN etc. exist because they support multiple OS's.  I suspect
the great majority of
package installs are on Windows.   In some cases, linux distros repackage
an entire CXAN in some
optional repository.  Many of these conversions can be done automatically,
but there are always exceptions.

Diversity can be a curse or a strength.   There has been progress but also
failures in efforts to deal with
linux package diversity.  The alien program converts between different
distro package systems, but
does nothing to resolve dependencies.

Virtualization methods can provide the environment needed by packages from
other distros, but
alien's conversionsMany people rely on conda to provide packages not
available from their linux
distribution, or to provide the same packages across several distros or
distro versions.

Packages are messy and likely always will be.  There is lots of room for
improvements to
make it easier to unravel conflicts, or even warn of potential conflicts.
 There has been work on
managing conflicts in Python: Managing Application Dependencies — Python
Packaging User Guide
.
For python, it is becoming common to have a separate python tree managed
with conda/mamba for
user applications and leave the system's python to the distro package
manager.

Re: Kinda OT: Email clients and Email Management

[c. marlow]

For everyone:

Just to follow up I wound up going back to POP and setting my email up
like Robert Moskowitz

I have Claws MOVE the emails to my local folders. 

I could of just had CPANEL forward all 5 of my email accounts to
the brand new gmail account, set that brand new gmail account up in
Claws as a POP account and then download everything that way I don't
have to wait for EACH IMAP account to update and then move the email to
the local folders. 

I guess that's something to think about... I am trying to compensate
being stuck on a slow satallite dish connection and use as little data
as I can since I only get 30 gigs a month and i've already ran out for
the month with 18 days left in my billing cycle. OYE VEY!

Oh, And SAT DISH connections ARE EXPENSIVE!!

I should of done that... I am on a mailing list that for some reason I
wasn't getting that person's messages and could only see what they said
when someone replied to them.. That would of worked perfectly in that
situation. 

I changed hosting providers.. I think that fixed it.

I dont mind people coming to me OL... Until they say mean and hateful
things in their email. And then, you get a special filter set up in your
honor that has Claws silently delete your emails and not let me know
that you sent me something :)

You can turn off Gmail's spam filtering:

*Create Filter*

in:spam ( never send to spam)

label:spam ( never send to spam)

is:spam ( never send to spam) 

And for an extra bonus:

TO = myaddr...@gmail.com ( never send to spam)

I didn't even know dnf had a colour (or color) option. It seems to be
off by default.

how to log machine activity

[Eyal Lebedinsky]

I am chasing a problem where I notice audio hiccups at regular intervals. It 
may be cron but I cannot see how.

I want to log start/end of every executable. I will do this for only a few 
minutes at a time.
I may want, later, to log all access to one fs to see if it matches what I hear.

I am on f34, x86_64, up to date. Surely there is a standard tool to do this (I 
hope)?

TIA

The benefit is that it's managed by the package manager, so it's easy to 
cleanly add, remove, and update it.  The alternative methods dump the 
files in various places and when a problem happens, you have to figure 
out where those problem files are.
