Thanks - looks like quoting is the answer.

[gentoo-user] OT: how does excel find commas within fields of a csv file?

[Adam Carter]

To clean up csv files I use excel's find/replace to swap the commas
occurring within fields for something benign. How does this magic work?
Different character sets within the same file?

Is it possible to do this with shell scripting?

[gentoo-user] 'make install' hijacked by installkernel ?

[Adam Carter]

I just tried to install a new kernel using 'make install' only to find that
the behaviour has changed and it appears to be running a bunch on
installkernel stuff.

'make help' says
  install - Install kernel using (your) ~/bin/installkernel or
 (distribution) /sbin/installkernel or install to
 $(INSTALL_PATH) and run lilo

So I guess that I want the 'install to  $(INSTALL_PATH) and run lilo'
behaviour that i'm used to. How to i get 'make install' to ignore
/sbin/installkernel ?

I think it's just that the default blocksize is (or was) very small (512
bytes?) so setting it to anything non-small helps a lot.

eg one example (from
https://superuser.com/questions/234199/good-block-size-for-disk-cloning-with-diskdump-dd#234204)
seems to show that most gains are in by around 16k. There's probably a lot
of testing noise in these results.

[gentoo-user] Choosing --param l2-cache-size

[Adam Carter]

>From https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87444 it appears that
l2-cache-size is a misnomer;
"A comment in driver-i386.c says:

  /* Let the L3 replace the L2. This assumes inclusive caches
 and single threaded program for now. */
  if (level3.sizekb)
level2 = level3;"

"Probably the --param should be renamed to last-level-cache". So for the
CPUs below that means L3.

For the CPUs i have handy;
AMD 3900X
$ lscpu | grep '[23] cache'
L2 cache:   6 MiB (12 instances)
L3 cache:   64 MiB (4 instances)

AMD FX-8350
$ lscpu | grep '[23] cache'
L2 cache:   8 MiB (4 instances)
L3 cache:   8 MiB (1 instance)

Intel i5-1340P
$ lscpu | grep '[23] cache'
L2 cache:   9 MiB (6 instances)
L3 cache:   12 MiB (1 instance)

What is gcc using when using -march=native? (I use distcc so cant use
=native).
AMD 3900X
$ gcc -v -E -x c -march=native -mtune=native - < /dev/null 2>&1 | grep cc1
| sed 's/--param/\n--param/g' | grep '^--param l2-' | cut -d' ' -f1,2
--param l2-cache-size=512
>>> so this is the l2 size divided by the number of instances, 6MB / 12 =
512

AMD FX-8350
$ gcc -v -E -x c -march=native -mtune=native - < /dev/null 2>&1 | grep cc1
| sed 's/--param/\n--param/g' | grep '^--param l2-' | cut -d' ' -f1,2
--param l2-cache-size=2048
>>> so this is the l2 size divided by the number of instances, 8MB / 4 = 2MB

Intel i5-1340P
$ gcc -v -E -x c -march=native -mtune=native - < /dev/null 2>&1 | grep cc1
| sed 's/--param/\n--param/g' | grep '^--param l2-' | cut -d' ' -f1,2
--param l2-cache-size=12288
>>> this is the l3 size

So i'm thinking the Intel CPU l2-cache-size is correct but;
for the FX-8350 it should be l3 / instances, ie 8192 / 1 = 8192
for the 3900X it should be l3 / instances, ie 65536 / 4 = 16384

Am I correct?
Thanks

That prompts the question - why do you want a VPN? (what do you think it
will do for you?)

If it's to get around geo-blocking, it's probably a good option if there's
no legal implications. If it's for something else it's probably worth
digging a bit deeper. If it's to try to avoid legal responsibility (eg. to
download copyrighted content), don't do anything you're not prepared to pay
the fine / do the time for.

I'm not an expert, but AFAIK VPNs don't offer any particular benefit with
regards to spam or script kiddies.

A VPN will;
- Hide your internet activity from your ISP
- Make your internet activity available to your VPN provider
- Make your internet activity available to your VPN provider's ISP

Without a VPN, your ISP could sell the details used to sign up for the
account (eg. name, phone number, email address) along with your internet
activity. With a VPN, the VPN provider could sell similar information,
however, there is typically an explicit claim that they won't do this,
whereas your ISP has probably buried information on what they do with your
information and metadata in Terms and Conditions documents. Your VPN
provider's ISP will be able to monitor your internet activity but it will
be mixed with the activity of the VPN provider's other customers, and they
won't have any of your sign up information.

I've heard some VPNs let you pay pseudo anonymously with crypto currency
(albeit with a cryptographically verifiable public ledger!), to prevent
direct matching of internet activity to an identity.

[gentoo-user] emerge 7-9% faster with python 3.11 beta 4

[Adam Carter]

FYI, i've found 'emerge -pvuUD world' is 7-9% faster on my machines when I
compare 3.10 to 3.11b4.

To achieve this i've added '*/* PYTHON_TARGETS: -* python3_10 python3_11'
to package.use on my ~arch systems, then run 'emerge -avuUD portage'. At
the end of this python-exec.conf contains;
python3.11
python3.10

and when i run 'emerge --version' it shows that 3.11 is being used.
Alternatively you could put 'python3.11' in /etc/python-exec/emerge.conf
and comment python3.11 out of python-exec.conf if you want 3.10 to be the
default and 3.11 to just be used for emerge.

Actually the free drive is nvme0n1... I was running out of space on that
device so added nvme1n1 and moved Gentoo to that drive. On nvme1n1
partition 1 is 1gig for both EFI and /boot (with a minimal .iso available
via grub as a rescue option if needed).

With regards to windows making a tiny EFI partition on drive 0, i dont
think I understand the issue. I'm thinking I can either;
1. Use the EFI boot loader to choose between Windows and Linux, as you
mention above, with the small downside of having two boot loaders/timeouts,
or
2. Use EFI to default to grub on the second drive with a very short timer
(so its like its not even there) and put an entry for Windows in the grub
config

I will probably try #1 first, then update the grub config to boot windows
and confirm that works, then change to #2.

Let me know if i'm misunderstanding anything.

Thanks!

[gentoo-user] Installing windows on second drive

[Adam Carter]

I'm assuming that windows will modify the EFI configuration and i will need
to boot, say, a minimal cd image to run efibootmgr to set it back, then add
a Windows entry to the grub config.

Is that correct? Anything else i should be concerned about?

If you put that url in a browser does it show your passwd file? I assume
because the logs say 200 it will.  If so shut down the httpd and reset all

Check your httpd config… seems odd that an old attack like this would still

Where N is the number of cores you want to allocate. zstd -T0 (or just
zstdmt) if you want to use all the available cores. I use zstd for
everything now as it's as good as or better than all the others in the
general case.

Parallel means it uses more than one core, so on a modern machine it is
much faster.

Genuine CPU issues seem pretty rare, so I would check for overheating or

IIRC MSIs have largely addressed the issue, so irqbalance is not so useful
anymore. Eg, /proc/interrupts on this system shows that the nvme drive gets
32 interrupts, and the intel gig eth card gets eight interrupts per port,
so there's no busy interrupts

I quickpkg'd harfbuzz and freetype, then tried to emerge --nodeps them, but
both failed at the configure stage.

Is there something else I should try?

[gentoo-user] postfix: /etc/postfix/aliases or /etc/mail/aliases ?

[Adam Carter]

I have an old log warning I want to clean up, and am assuming that the
aliases and aliases.db file would typically be in the same directory. When
the postfix service starts at boot;
postfix/postalias[607]: fatal: open /etc/postfix/aliases.db: Read-only file
system

The location is currently configured in main.cf;
# postconf alias_maps
alias_maps = hash:/etc/postfix/aliases

And looks like the installer puts the original alias file there too, so I
assume my config is per the default config;
# qlist postfix | grep aliases
/etc/postfix/aliases

But this;
# grep aliases /lib/systemd/system/postfix.service
ExecStartPre=-/usr/bin/newaliases
ReadWritePaths=-/etc/mail/aliases.db

Suggests that /etc/mail is the correct location, so i'm wondering if i
missed an update to postfix.service. Can a postfix user please check their
ReadWritePaths to see if it's /etc/mail/aliases.db or
/etc/postfix/aliases.db ? Cheers.

I've noticed that my gdm system is running /usr/bin/Xwayland instead of

now.

Can i try Xwayland with startx?

pstree shows the execution paths as below. Inscrutable to me and

It may have been possible to use --changed-use and not add any python
target entries, or, it may be that you only need a very small number of
entries when using --changed-use.

You could try commenting out the target entries then running emerge -pvuUD

After seeing Grant's mention of CAA records I think I may have conflated
pinning with them, or perhaps there were some special controls in Chrome to
check that google certs were issued by the correct CA? Sorry i'm not clear

You should add --changed-use to your emerge flags and clean any
PYTHON_TARGETS cruft out of package.use. On ~arch the default python has
just changed from 3.8 to 3.9. You may well find --depclean will remove 3.8

CAs who issue such dodgy certs tend to get booted from certificate stores,
since they cannot be trusted.
https://wiki.mozilla.org/CA:Symantec_Issues#Issue_D:_Test_Certificate_Misissuance_.28April_2009_-_September_2015.29

https://en.wikipedia.org/wiki/Certificate_Transparency helps keep CAs
honest.

The way i like to frame it is "any certificate should only be trusted as
much as the *least* trustworthy CA in your certificate store"

AFAIK in an enterprise MITM works by having a local CA added to the cert
stores of the workstation fleet, and having that CA auto generate the certs
for MITM. That didn't work with certificate pinning, but pinning has been
deprecated.

Yes, I imagine there are some circumstances where it would make sense to
remove all the certs from your certificate store and then just add your
local CA's cert. In this case, the least trustworthy CA in the store is
your own :)

Yep, but the system is already at its full RAM, so we're in
workaround/tactical solution territory. Any system that needs 24gig swap to
support 8gig ram is going to really suck.

Might be worth adding zswap using zstd or lz4 to your config (uses more CPU
for less IO)
https://www.kernel.org/doc/html/latest/vm/zswap.html

If you want to see which processes are using the most memory, run top then
type 'M' to have top sort by memory instead of CPU. You can also type 'm'
to make top show the memory numbers as an ascii bar graph. The man page
explains what VIRT RES SHR mean.

On systems that I setup assuming I wouldn’t need swap, I set swappiness low
and add a swap file (on ssd if possible) so the bigger builds can at least
finish, albeit more slowly. Generally swap never gets touched. I also use
zswap with zstd or lz4, which perform better than the old lzo deflate/zlib
options, sometimes by a wide margin.

I don’t bother with /var/tmp/portage on tmpfs any more as it seemed to be
more trouble than it was worth.

Great.

Ok i see 3.10 was released 2013-06-30, so looking for a cpu released the
previous year, say
IvyBridge, IvyBridge-IBR Intel Xeon E3-12xx v2 (Ivy Bridge, 2012)

x86 IvyBridge-v1  Intel Xeon E3-12xx v2 (Ivy Bridge)

x86 IvyBridge-v2  Intel Xeon E3-12xx v2 (Ivy Bridge, IBRS)


So if I run the following then RHEL will think it's running on an IvyBridge

[gentoo-user] bonding round-robin for scaling bandwidth for a single flow

[Adam Carter]

I've been trying to replicate the results from;
https://louwrentius.com/linux-network-interface-bonding-trunking-or-how-to-get-beyond-1-gbs.html

To get over 1 Gig throughput for a single flow out of a 2x1GB bonded
connection. Presumably its only client→server file transfers that are over
1GB, as in this configuration the server is using LACP.

The setup is per the above, so; Switch: Netgear GS716Tv3 Client: bond uses
'Bonding Mode: load balancing (round-robin)'. The switch is configured as a
static trunk for those two ports Server: bond uses 'IEEE 802.3ad Dynamic
link aggregation' with Transmit Hash Policy: layer3+4 (shouldnt matter),
and the switch is configured as an LACP trunk for those two ports.Testing
using iperf3.

I can see the Client sending roughly equal numbers of packets down both
interfaces, so it looks like round-robin is working fine. The responses
from the server come back on a single interface, but i'm assuming that's ok
as they're just acks. Wireshark says the packet capture of the bond
interface of the server is full of 'dup ack', 'previous segment not
captured', 'tcp out of order' which I assume means that there's packet
forwarding jitter on the low end switch. Perhaps it could work with a
better switch?

Thanks for any ideas on this.

As the 20 odd MB/s you're getting is above what is possible on 100M
ethernet, you can rule out any ethernet interfaces at 100M.

Can you describe the network between the two systems with the slow transfer?

If there is a fast WAN from one side of the globe to the other it could be
latency related. OpenSSH used to have a fixed internal window size that
made it slow on high bandwidth high latency links, and I notice the hpn USE
flag still exists in the openssh ebuild, which implies the issue with
openssh still exists. Rsync can use either ssh or its own protocol, so if
there's a high latency link between the two boxes and rsync is using ssh,
you could investigate rebuilding openssh with +hpn.

What does ping show the latency as?

Otherwise i'd be thinking about packet loss. First place to start for that
is on the endpoint interfaces;
ifconfig enp35s0f0 | grep err
RX errors 0  dropped 0  overruns 0  frame 0
TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

If 'grep -i python /etc/portage/*' is not empty, try making it that way. On
my system with 1323 packages, having these empty and running emerge -avuUD

Try emerge -avuUD @world (the U is the critical bit). For me, it pulled in

For secondary IPs use eth0:0 as the interface name;
# ifconfig bond1
bond1: flags=5187  mtu 1500
inet 192.168.1.252  netmask 255.255.255.0  broadcast 192.168.1.255

For the routes, your eth0:0 interface will of course need to use
192.168.10.1

However, if you just have a PC with a single interface, and you are going
to just manually plug in which ever router you want to use, then just use
dhcp on eth0, and plug/replug the cable. The loss of link on the cable
should cause dhcp to DISCOVER again, and then get the correct IP and
gateway - so no changes will be required on the PC (assuming i understand
your setup correctly)

I think call traces indicate a kernel bug, not an issue with kernel
configuration. Try .71 - perhaps the issue has already been fixed.

If the issue persists in .71 then you could report to the kernel

Usually when you forward X over ssh, DISPLAY is a port on the ssh client,
which is then forwarded by ssh to the remote port, that is, the port on the
remote server that the X server is listening on. So putty should be
automatically setting DISPLAY to something like  192.168.56.25:10.0 (ie
port 6010 on the guest) when you enable X forwarding. If it's not i'd say
there's something wrong with the putty setup.

That said, i think you should be able to just connect directly to
192.168.56.1:0.0 anyway - does Xming have an xhost setting? Does netstat on
the host show its listening on port 6000? Windows firewall?

I leave everything at the defaults, unless there's something that i'm
certain I want to achieve. This goes for all settings, including USE, and i
usually use package.use rather than USE= in make.conf.

So for me there's no specific python/ruby etc settings in make.conf, but
there's still eselect, and i generally keep away from the newest and oldest.

Try unsetting python settings in make.conf and run an emerge -avuUD world
to see what you get.

BTW, for ~arch users python:2.7 is pretty much gone. For me, I just have
some gnome stuff which depends on dev-libs/gjs, which depends on
dev-lang/spidermonkey:68 which depends on python:2.7.

Performance wise, ext4 and XFS lead most benchmarks for non-raid. XFS seems
best for raid1, so I imagine either of those would be best for raid0.

Depends on your use case, but ext2 (and to a much lesser degree btrfs) will
be less reliable than ext4 or XFS so what you use will depend on
speed/reliability trade off. ext2 is less reliable due to it missing the
journal, btrfs due to being less mature (IMO, this is a weakly held
belief). Also btrfs tends to be slower than ext4 and XFS for most
operations, sometimes by a large margin.

No, nothing in /etc/portage/* System is testing/~amd64.

However, qlop shows the last rust-bin installed was actually 1.38, whereas
my memory was that it was 1.44, so i have mixed up two different systems. I
can't see anything in roots history that would have caused the issue.

FWIW if i mask dev-lang/rust-bin it wants to

Added the following to package.mask and world will update without complaint
dev-lang/rust-bin

[gentoo-user] repoint virtual/rust to rust instead of rust-bin

[Adam Carter]

I've unmerged rust-bin, emerged rust (v1,45), then re-emerged virtual/rust
but if i run a world update it still wants to pull rust-bin back in;

# emerge -avuD --tree world

These are the packages that would be merged, in reverse order:

I cut and pasted the output into what my brain thought was a sensible order.

The problem is with pygobject, so what does it need?
USE="cairo -examples -test"
ABI_X86="(64)"
PYTHON_TARGETS="python2_7 python3_6 python3_7 -python3_8"

So out of that stuff, what does pycairo-1.18.2 have that pycairo-1.19.1 is
missing?
1.18
USE="-doc -examples -test"
PYTHON_TARGETS="(-pypy3%) python2_7 python3_6 python3_7 -python3_8
(-python3_9)"
1.19
USE="-doc -examples -test"
ABI_X86="(64)"
PYTHON_TARGETS="(-pypy3) python3_6 python3_7 -python3_8 (-python3_9)"

Ok so 1.19 doesn't have python2_7, so while pygobject is using it, pycairo
will need to have it. So, you tried rebuilding pygobject without 2_7, and
luckily nothing else that was using pygobject needed 2_7 so it worked.

I think it's because dev-python/pycairo-1.19.1 doesnt have python2_7 (which
dev-python/pycairo-1.18.2 does) and pygobject requires it. You could try
removing python2_7 from pygobject but i'm guessing there will be other
dependencies that wont allow that.

FYI this issue is due to fallocate creating files with holes (found via

I was watching CPU temperature with watch 'sensors k10temp-pci-00c3' and it

I'll try a new power supply & memtest. Thanks.

[gentoo-user] /proc/meminfo vs lshw -c memory

[Adam Carter]

The BIOS and lshw -c memory shows 2x8Gig but the OS (/proc/meminfo) only
shows 8Gig. I've re-seated the RAM, tried different slots, booted from CD,
but no change. Last time i looked the OS showed 16Gig.

Is there anything else i can try or is it new RAM time?

XLR style mics output to too low for sound card inputs, so let's assume the
Behring interface you have is boosting the signal (and since its an
amplifier it gets its power via USB). The question now is whether the
signal on RCA outputs is suitable for a sound card - i'm not sure, but IIRC
i've done this before and it worked.

I'd be inclined to try setting up the Behring USB though - if its a high
end device it will probably sound better.

If your breakage can be fixed by busybox, then its easier, faster and
avoids downtime when compared to booting from alternate media. As its
statically linked, it will still run if any libraries required by the
conventional binary are stuffed (BTDT). Of course, sometimes its not enough
and you will have to fall back to booting from alternate media.

I don't think many will find a compelling case for its removal.

Yep, everything's on the nvme except /var. From grub to console login
prompt is about 20 seconds, but it waits quite a while for the network
service to come up, perhaps because its using a bonded interface.

Booting is quick, but I really notice the speed when booting a win10 vm in
virtualbox, which takes about 15 seconds.

The system was delivered with the RAM running at 2133, so the auto speed
detection hadnt worked. Hardcoding it to the spec speed of 3200 took the
cache reads from 11.9Gig 15.2Gig...
