ssd keeps dying (OT)
by Neal Becker
I know this is a bit OT, but you guys are great at answering all questions.
I bought a workstation from Titan computers around 1/2020 (dual EPYC cpu).
After about 1 year it stopped working. I could ssh to it, and almost any
command would return Input/Output error. Unfortunately journalctl gave
input/output error so I can't see logs. cat /proc/partitions did not show
any nvme device (the root device) on which the OS was installed.
I replaced the SSD with a samsung 980 pro. Reinstalled fedora. It then
worked a few weeks, then the exact same symptoms.
I replaced the SSD with another samsung 980 pro, this time with heatsink.
Reinstalled fedora. It worked a few weeks. Then same symptoms.
Then I replaced with a 4th samsung 980 pro, but this time instead of using
the M.2 socket I used a pcie-m.2 adapter (in case something was wrong with
the m.2 socket). Also added a surge protector outlet for good measure.
Reinstalled. Watched the smartctl. No errors. Temperature was always low.
Now it's failed again, exactly same symptoms.
Any ideas?
Thanks,
Neal

Re: If venv is a reality can I build a program python wit it for more

No, venv won't give you any additional security if a python module has
malicious code.
If you don't fully trust a python module but you want to run it anyway,
consider building a container image. You can install the required
python modules in the image, and then run them the container mostly
isolated from the rest of your system. If it needs data files (and I
expect that it does), then you can mount a single directory as a volume
in the container so that the python modules have access to those files
but nothing else on your system.
Or, if you don't trust the isolation of containers, then use a virtual
machine.

iptables-restore-translate
by François Patte
Bonjour,
I would like to move from iptables to nftables which seeems to be the
nowadays firewall and there were an app to translate iptables rules into
nftables rules, but some (clever) packager seems to have withdraw this
command from the iptables-compat package which installed on my f34
install.
I tried to uninstall this iptables-compat (succeeded) and to install the
iptables-1.8.7-3.fc34.x86_64 package but failed for some obscure
reasons...
Is there a way to have this translator available somewhere?
Thank you.

dns lookup behavior
by 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.

Perl is now failing for me
by Fulko Hew
I'm not sure when it started, but on everything more complicated
than print 'Hello World' my perl is failing.
For example:
$ perl -e 'use DateTime;'
Attempt to reload List/Util.pm aborted.
Compilation failed in require at /usr/share/perl5/vendor_perl/namespace/
autoclean.pm line 11.
BEGIN failed--compilation aborted at /usr/share/perl5/vendor_perl/namespace/
autoclean.pm line 11.
Compilation failed in require at /usr/lib64/perl5/vendor_perl/DateTime.pm
line 9.
BEGIN failed--compilation aborted at
/usr/lib64/perl5/vendor_perl/DateTime.pm line 9.
Compilation failed in require at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
or
$ cpan
Attempt to reload Scalar/Util.pm aborted.
Compilation failed in require at /usr/share/perl5/Safe.pm line 4.
BEGIN failed--compilation aborted at /usr/share/perl5/Safe.pm line 4.
Compilation failed in require at /usr/share/perl5/vendor_perl/CPAN.pm line
57.
BEGIN failed--compilation aborted at /usr/share/perl5/vendor_perl/CPAN.pm
line 57.
Compilation failed in require at /usr/share/perl5/vendor_perl/App/Cpan.pm
line 290.

/usr/share/perl5/vendor_perl/App/Cpan.pm line 290.
Compilation failed in require at /usr/bin/cpan line 7.
BEGIN failed--compilation aborted at /usr/bin/cpan line 7.
Since I last saw it working, all I can do is remember
upgrading to F35, or the daily updates.
Can anyone suggest where to start?
For example... Why is it trying to reload Scalar::Util?
