Thunderbird filters -
by Bob Goodwin
I have installed and updated Fedora-33-Beta with XFCE.
I have a problem configuring the received mail filter. I can create sub
directories under inbox but the mail filter setup gui does not show them
as available to send messages to. I have set up these filters many times
and it normally works without problems but not this time.
Am I the only one having trouble with this?
Any suggestion appreciated, Bob

Firefox Clear History not clickable / F33
by Michael Schwendt
This is with default Fedora 33 Workstation x86_64.
Firefox > History > Clear Recent History > Time range to clear
The combobox can be clicked to show the drop-down list, but none of the
shown items can be selected with a mouse-click. Using cursor keys is the
workaround.
Can anyone reproduce that?

An "arp ... pub" replacement?
by Steve Hill
I'm looking for advice on best practice for setting up a Fedora / CentOS
firewall in the following situation:
LAN (10.0.0.0/24)
|
|
| (10.0.0.1)
Firewall
| (198.51.100.2/27)
|
| (198.51.100.1/27)
ISP's Router
|
|
|
Internet
In addition to 198.51.100.1 and 192.51.100.2, the ISP is providing 28
extra public IPs (192.51.100.3-30), and I want to the firewall to be
able to DNAT those IPs to internal machines, which means it needs to
answer ARP for them.
The router is routing all of the public IPs directly to its internal
NIC. In an ideal world, we'd just reconfigure the router so that the
IPs are routed via the firewall rather than being directly connected.
However, I'm finding that for managed routers, ISPs are increasingly
unwilling to set up custom routing.
The available options seem to be:
1. Add aliases for all of the addresses onto the internet NIC of the
firewall. You used to be able to create an
/etc/sysconfig/network-scripts/ifcfg-eth0-range0 file with the address
range in it and have the network scripts automatically add the aliases.
Unfortunately NetworkManager no longer seems to support this. Also this
feels quite messy because you end up with a lot of addresses attached to
the NIC, and strictly speaking those addresses don't really belong to
the firewall since they are intended to be forwarded through to internal
machines.
2. Route 198.51.100.0/27 to a dummy NIC and enable proxy ARP on the
internet NIC. Proxy ARP is a fairly blunt tool and will cause the
firewall to answer ARP for any address, not just that subnet.
3. The only thing the firewall actually needs to do with these addresses
is answer ARP requests for them. It used to be possible to use the arp
command to set this up with something like:
arp -i eth0 -Ds 198.51.100.0 eth0 netmask 255.255.255.24 pub
This method is documented in TLDP, but the arp command is long
deprecated in favour of "ip neigh" which doesn't appear to support doing
this.
Can anyone advise whether any "best practice" for this kind of setup exists?
Thanks.

F32 can't print
by Robert Moskowitz
HP printer. First time printing since unsuspending Sat night, but
printed fine Friday.
Output is just pending in the print queue.
I did a 'systemctl restart cups'
and no change.
I can print fine from another computer, so how do I troubleshoot this
and fix it? Other than a reboot?
thanks

install to removable drive?
by Michael Hennebry
Can F32 be installed to a removable drive,
e.g. an SD card in a USB SD card reader?
If so, any traps or tricks I should know about?

OT: Checking fedora shell script for errors?
by Michael D. Setzer II
Recently, had an issue with firefox script creating a zombie because of
an error. They fixed it, but then created another error since missed a
space after a [, that was then corrected.
In some emails, learned about shellcheck package..
Have done some testing to check scripts, but just started.
In looking at /usr/bin on my machine, there are just under 5,000 files, but
only 488 are shell scripts. So, created a little script that will run against
all script files, and create an file with results.
Current version is shellcheck-dir3
#!/usr/bin/bash
if [[ "$1" != "error" && "$1" != "warning" && "$1" != "info" ]] ; then s=style; else
s="$1"; fi
echo -n "" >/tmp/"$s"-out
for a in ./*; do file "$a" | grep -E '(/ksh script|/dash script|/sh script|Bourne|POSIX)' |
cut -f 1 -d: ; done >/tmp/file-list
time while read -r line; do shellcheck -x -W 0 -S"$s" "$line"; done </tmp/file-list
>>/tmp/"$s"-out
#create uniq listing of errors found?
grep "\-\- SC" </tmp/"$s"-out | sed 's/.*^//' |sort | uniq > /tmp/"$s"-summary.out
runuser -u $USER gedit /tmp/"$s"-out /tmp/"$s"-summary.out
shellcheck has 4 security levels (error, warning, info, style)
error limits the reports, but gives about 688 lines with /usr/bin.
Each lower level reports more and more suggestions.
Some errors are simple. Number of script the exit -1, but reports that exit
values are suppose to be 0-255, so basically the -1 becomes 255. But
some look like they might cause real issues.
Just interesting to look out. Originally used a for loop, but ran into some
issues, so switch to the while that even handles files that contain spaces.
Thanks for any suggestions.

off topic -- older centos -- ff sound issue
by bruce
Hi.
Feel free to disregard as you see fit.
Trying to debug/resolve a sound issue. The base OS is an older Centos
7. It's running FF 78. - pulseaudio is running.
Sound works with the Chrome browser. However, can't seem to figure out
why sound is not working with FF! The FF app isn't appearing in the
"sound applicaition" gui when running vid/audio.
I've checked the preference box to disregard hardware in FF. I've
looked/researched the net as well.
Thought I'd turn here as last resort.
Any possible things to check?
thanks

Strange gpg-agent processes with Fedora 32
by Michael Schwendt
Has anyone seen the following before and possibly has found out what is going on?
Fedora 32 shows a gpg-agent process for each repo but with a non-existant ".tmp" homedir.
Examples:
root 2512 0.0 0.0 161028 900 ? Ss 11:20 0:00 gpg-agent --homedir /var/cache/PackageKit/32/metadata/fedora-32-x86_64.tmp/gpgdir --use-standard-socket --daemon
root 2527 0.0 0.0 161028 896 ? Ss 11:20 0:00 gpg-agent --homedir /var/cache/PackageKit/32/metadata/updates-32-x86_64.tmp/gpgdir --use-standard-socket --daemon
