Re: [gentoo-user] Small (as in footprint) window manager

# ssh -Y @

"@" is optional. Without it, ssh will use the username you are using 
on the client.
"" is either an IP address or, if you have a hosts file or DNS server 
configured, the hostname.

The "-Y" sorts out the forwarding for X applications.

Does it show up when you search for that config-item from within "make

Not all config-items end up in the config-file, especially if pre-requisites

I have the same experience, when using ink-based printers. My current 
Laserprinter doesn't seem to want to die.

I tried that once, the quality of the results was really bad. I ended up 
borrowing a proper negative-scanner from a colleague. That was a windows-only 
one, but the quality of the scans more than made up for having to use that. 
(And using VirtualBox, I got better performance, eg. scanspeed, than when 
using windows native)

I got a colour laser all-in-one, it's nearly 8 years old and not had any 
problems with it. Would like to replace it for a double-sided (print and scan) 
version though.

Try old office buildings, they do remove them as cost-saving exercises on 
occasion, you might be able to pick one up? (you do have a big car/van/truck 
to move it?)

I usually do a full rebuild of everything (using --empty) in a chroot and then 
update using binary packages on the main system if I haven't done an update in 
a long time.

If it's just python you want to be sure of, you can check the "Version

In short:

"No longer maintained" = "If something breaks, you can try to fix it yourself"
"Complete" =(usually)= "All functionality works at time of testing"

In general, if the drivers are Open Source, someone somewhere might still be 
maintaining this if anything does break. If there is a binary blob required to 
make it work, it depends on how this part actually works.
If it can be treated like an appliance (eg. with input X will always do Y and 
output Z), then you can ignore the fact it is a black box.

Even with Raid-firmware, they can be configured for JBOD.

I would suggest ZFS or BTRFS over mdadm. Gives you more flexibility and is a

IMHO, ZFS is nice for large storage devices, not so much for regular desktops. 
This is why I am hoping BTRFS will solve the resilver issues. (not kept up, is 
this still not working?)

I only encounter this when people decide to unplug the disk without ejecting 
it. The eject forces a clearance of the write-cache.
This is why I always get annoyed with people who simply pull out the disk/

I would assume other desktop environments will also seamlessly work with 
ntfs-3g as that is handled by udisks.

Personally, I have not noticed lesser performance with ntfs-3g with both

Gentoo-sources-4.14.65 is stable in the tree. Which is quite recent.

I just tested this on my system as well and am seeing the same (apart from the 
masked ones).
I agree that I would expect only "dev-python/wxpython" to be shown.
"eix wxpython" does work as expected.

You really want to be at the server or at least have some kind of access to the 
keyboard and screen to coordinate booting to a different environment before 
enabling multipath.

You need to change all the devices from whatever they are now to the multipath 
versions, which is best done when booted into a live-environment instead of the 
actual production one.

The idea is:
Disk(/dev/sd?) - (multipathd) - virtual (/dev/mapper/???) - (filesystem)

If the current system is pointing at /dev/sd?, you are bypassing multipathing.

Also, important and should be obvious, the kernel must have multipath support 
enabled in de device-mapper section.

I was able to get it all working before doing the rest of the system.
On my system, I didn't have to change the default configuration of multipath as 
it autodetects which sd?'s are pointing to the same disc due to serial numbers 
and ZFS is happy to sit on top of that.

Wifi is a shared medium. Which means that if you have other people living 
nearby, your wifi connection will suffer.

I managed to pull network cabling through the pipes containing phone and coax 
cables. This allowed me to wire up the study, living room and server room.

Mentioned this as well. :)
It works if the user wants this to work. From what I understand, the customer 
of OP wants the record. Which means I would expect OP not to try to get out of 
it.

From what I read, it records user, processname and other statistics. I would 
assume this would cover more than what OP requested. It also would record 
script contents.
But not sure if it would also record full commandlines and I/O actions.

All,

This piqued my interest and decided to google a little bit.
Found the following, which might help:

https://askubuntu.com/questions/93566/how-to-log-all-bash-commands-by-all-users-on-a-server

Same method is described in:

https://serverfault.com/questions/323270/how-can-i-make-bash-to-log-shell-commands-to-syslog

This will help if all you do is working within bash. If you switch to a 
different shell or run scripts, the logging obviously fails.

Another method might be:
https://www.linuxjournal.com/article/6144

This is an older document, but might still be made to work as it uses "process 
accounting" which is still in the kernel afaik.

Multipath devices end up under /dev/mapper/...

SSH can (it does by default) use PAM for authentication. I would suspect it

Xen logs all output of the VM to a text file if it is started automatically. 
This is done by attaching it to a screen-session and having screen log it all 
to a text file.
If there is a reliable method to force SSH-sessions into something like this, 
you can log all input and output.

If the printer requires a near constant stream of data over the USB port, you 
might want to look into a physical cable instead of wifi for the communication.

Current code is too specific for my situation. I think you would be quicker to 
write something yourself instead of modifying my code.

The steps are:
- Check if an snapshot needs to be done (incl. type: hourly, daily, weekly, 
monthly)
- If yes:
1) create a recursive snapshot on the entire pool
2) remove unnecessary snapshots (temp, swap, 
placeholders,not_for_current_type)
3) register snapshots into database
4) clean up old snapshots

Because I register actual snapshots and point snapshot-type entries to these, 
I can quickly determine which snapshots are really unecessary. This also 
drastically reduces the amount of snapshots on the system. (My SAN currently 
has 2611 ZFS snapshots).

I also found it is far quicker to create a recursive snapshot on the entire 
pool and then removing all the unecessarily created ones.

I tried sanoid, but it has a few problems which really become annoying when you 
have a lot of datasets:
1) every dataset is handled seperately, no use of recursive snapshots when 
datasets are inside the same tree
2) it keeps seperate hourly, daily, snapshots, which means it will happily 
create multiple snapshots with only a few seconds difference for every dataset 
around midnight.
3) when rolling back several snapshots, there are multiple errors reported 
because the cache (where does it store that?) does not match reality.

Have these been resolved yet?

I ended up writing my own system for this, got some extra intelligence in there 
to work around any possible error condition I have encountered.

I haven't found many good ones.

I see this sometimes when:

2) I connect to an X-session using "X2Go"

I haven't had this happen recently though, not entirely sure what solved it as 
I have been playing a lot with settings and "emerge -e" on the single machine

No need to add Kerberos to the mix.
I use LDAP along with nss_ldap. (Various howtos available online)

It works fine.

Not to my knowledge.
I use OpenLDAP for my users and groups and this has worked perfectly ever 
since I implemented it.

I am only familiar with CIFS/SMB and NFS. Not sure if any other shared 
filesystems handle this. A minimum requirement would be that you need to login 
to the fileserver using a username and password.

I found NFS to be stable for long term (months) connections. When working from 
mobile machines (Laptops), I use SMB/CIFS to access the same files.

There is. You have (at least) 2 other options:

1) In the "/etc/conf.d" files (as I tend to do):
# grep need /etc/conf.d/postgresql-9.5
rc_need="netmount"
(This means, postgresql-9.5 needs the 'netmount' service to have started first)

# grep need /etc/conf.d/netmount 
rc_need="net iscsid"
(This means, netmount needs 'net' and 'iscsid' started first)

2) /etc/rc.conf
See the following section in the default version:
===
# It's possible to define extra dependencies for services like so
#rc_config="/etc/foo"
#rc_need="openvpn"
#rc_use="net.eth0"
#rc_after="clock"
#rc_before="local"
#rc_provide="!net"

Sounds like a bug.
All fetch restriction packages I encounter want it in your distfiles folder. 
(Wherever you configured it to be)

I haven't really read the text on these myself lately, so not sure if other 
packages have the same, but I didn't notice any path other than my distfiles 
dir.

Most common one I have is the citrix 'icaclient'.

I would recommend more RAM. (And no, that isn't a joke because you said you

Aleksander,

You might want to change your initramfs config to not include the nvidia module 
to avoid this in future.
I don't have it in my initramfs and don't experience any issues as it ends up 
being loaded correctly after the initramfs.

Do you use an initramfs? And if yes, does it maybe contain the nvidia module?

My current HP one can scan and print directly to/from USB drives. No need for 
a computer.
Newer HP printers can also scan to fileshares, email, just like most other

"modules-load" is, by default, not part of any runlevel.

It is a dependency for "modules", which is (on my system) in the boot

You probably received 182750.

I used to get these messages, this was caused by bad behaving spam filters on

On a system with the same mainboard:

zcat /proc/config.gz | grep -i drm
# CONFIG_DRM is not set


Eg, DRM is not necessary.

I don't reboot often enough to find it necessary to "fix" the UEFI boot. Mine

Actually, it doesn't. But lets not discuss naming conventions. A lot of tools 
have ones where I fail to see the logic.
It's a shame that option is not easily findable. And not knowing it exists, 
means checking man-pages and googling for them doesn't happen either.

True, except with OpenRC, all the config is located together. Not mostly in /
usr/ somewhere with overrides in /etc/...
I dislike all tools that split their config in this way.

> So it's actually not an argument for why you'd dislike systemd. ;-)

The lack of easily findable documentation on how to stop a service from 
starting, even as a dependency, is a reason. (not singularly against systemd).
Systemd, however, has an alternative.

I may not agree with Canek on all things:
- I do dislike systemd, especially on Centos where disabling services doesn't 
always work past a reboot
- Users who can't write code also have a right to be heard and their wishes 
should still be honestly considered

But the conversations have always been civil. And information from him has 
always been helpful. He is one of the few people on this list whose comments I 
read and who I do miss when there isn't something for a while.

Canek bases his "being a fan of systemd" on what he needs and wants from a

I have not seen any indication that BTRFS raid 5/6/.. is usable.
Last status I heard: No scrub, no rebuild when disk failed, ...
It should work as long as all disks stay functioning, but then I wonder why 
bother with anything more advanced than raid-0 ?

It's the lack of progress with regards to proper "raid" support in BTRFS which 
made me stop considering it and simply went with ZFS.

Add the load average part to the makeopts and make will keep the jobs down when 
load rises.

I would let the mailstore (Cyrus, Dovecot,...) do the actual storing of the 
email and have the MTA (postfix, sendmail,...) pass it via LMTP or similar.

That way any indexes and metadata is handled properly.

Interesting,

I use kmail a lot on my desktop and laptop and have not noticed that in a very 
long time.
It has actually been quite stable.

I do use IMAP (cyrus) and akonadi is configured to use a postgresql database 
which is not running as embedded under my own user.
(Postgresql is configured as a proper RDBMS using it's own user)

I wonder of part of the issues most people are seeing is because of the default 
of using mysql embedded?

2nd time the dependency might have been installed already.
Sometime it hasn't.

This can also cause a failure when not using parallel builds for exactly the 
same reason.

No, it won't.
If it has multiple packages that can be built (taking dependencies into 
account) it will. If all packages in the queue are waiting for a single 
package to be installed, all those will wait till that package is finished.

I thought so too.

Don't forget to add the "load-average" option to both, otherwise there is a 
very likely chance you will have 3 * 7 = 21 build processes running at the 
same time.

Also, I have had situations where using "-j" actually caused some issues where 
it was picked up by the wrong process or it has a different meaning for some 
other process. Specifying the long version (--jobs) has been reliable for me.

Instead of all these aliases, simply edit your make.conf ( /etc/portage/
make.conf )

And edit (or add) the following lines:
MAKEOPTS="--jobs 24 --load-average 48"
EMERGE_DEFAULT_OPTS="--jobs 24 --load-average 48"

Adjust the values to match your system, the above works fine on my desktop.

According to gkrellm, my GPU is at 24C. CPU is at 31C.
Will check it after running a few 3D heavy apps later tonight.

I have a Geforce GTX 950 and it does show the processes.
Surprisingly, some desktop apps (not all) are also showing, must be linked to 
some library.
Also shows the GPU memory usage.

That's one option.
Also make sure the sync succeeded and didn't fail due to insufficient disk-

One possible cause:
Some left-over libraries in memory that weren't cooperating.
Someone with more knowledge of this might let us know if this theory of mine

Mine couldn't get rid of the hot air at all...
The SCSI-controller was in the bottom PCI-slot.
The flat-ribbon cable was going nicely straight up
The CPU was between the cable and the front of the case... Nowhere for hot air 
to go (unless you count a little gap)

That was solved by drilling vent-holes in the case-cover. (Case was basically 
cast-iron...)

Also check it is not overheating.
The one time I had random gcc segfaults was when I accidentally forgot decent

I stand corrected. Forgot about this possible avenue. But this will still 
require the person already has access to the system.
I think for most users with just a personal desktop, this is less likely.

It does bring another possible access, most servers have iKVM/IPMI systems 
installed for remote management. Those also allow USB devices to be connected 
over network. I would, however, class access to these parts of the system as 
"physical" access.

From what I read, you need physical access.
And I am not certain what you need to do to the firmware on the USB device to

If you run it from a seperate account (ssh -Y facebookuser@localhost ) you can 
stay with firefox. Just keep that one for facebook only.

I tried Tor once to see how it works. The network performance is too slow to be

Run a dedicated browser in a dedicated user account. This should isolate any

That might have happened automatically as portage tends to want to unmask the 
latest version if it can't find an unmasked version that matches requirements.

I always answer "no" to those requests and copy/paste the actual lines myself 
after checking they are really what I want.

check your keywords, how did you unmask zfs?

Here are mine:

$ grep -r zfs /etc/portage
/etc/portage/sets/zfs:sys-fs/zfs

If that is picked up by a developer, then yes.
My experience with providing bugs with ebuilds is that they get closed 
eventually due to open security bugs (fixed in supplied versions for a few 
years) and lack of maintainership.

Interesting, but I still consider multiple emails inside a single file a recepy

Actually, I used to do this a lot using a webmail client (when I was still 
able to run squirrelmail without having to change back to an old PHP version) 
and never actually had any issues with this.
Neither with reiserfs or ext4.

I would put that down to either hardware or issues with the chosen IMAP-
server. For reference: I have been using Cyrus for a very long time.

My last rebuild was earlier this year, my mail had already been migrated to 
ext4 without issues. (Did not notice any performance issues)

My mailserver (Cyrus) uses ext4 for the mailboxes.
This is on a partition which is accessed via iSCSI.
Which is a zvol on a ZFS pool.

Eg: disks <-> ZFS <-> zvol <-> iSCSI <-> ext4

I am not noticing any significant performance issues, the ones I am can be 
resolved by adding a dedicated SLOG en L2ARC, but this will only help the 
systems hanging in the rack as those are connected with a 20Gbe link. Rest of 
the systems won't get more than 1Gbe.

I have several large mailboxes:
- postgresql-hackers = 195,000 items
- gentoo-user = 240,000 items
- Xen-devel = 366,000 items

The others are below 100,000.
I use these as archives and regularly search through these before reverting to 
Google or asking on the relevant mailing lists.

mdbox? Is this a single file per mail folder?
The main reason I switched to maildir several decades ago was precisely the 
issues (by design) mbox has.
A single corrupted email WILL kill the entire folder.

I had a large partition with reiserfs.
Running fsck always failed due to running out of memory.

Partition was quite a bit larger than 2TB (around 6TB) and contained a huge 
(millions) amount of files, but having an fsck become impossible with 16GB 
memory available was rather annoying.

A 32bit userspace can run with either a 32bit or 64bit kernel.
A 64bit userspace can NOT run with a 32bit kernel.

As you currently have a 32bit kernel, I am assuming a 32bit userspace. A 64bit 
kernel should not cause issues.

I have no experience with Linode. Can't they assist with this?

Personally, having a forced change like this would make me reconsider the

These got updated at some point.
For Xen-guest, I specify:
# rc_sys="xenU"
for KVM guests (got 2 running in the "cloud"):"
# rc_sys=""

If 'rc_sys' is not set, openrc tries to auto-detect.
If it is set, it will not auto-detect and use whatever you specified.

aargh...
I stopped using those WD drives, if you want to disable that part, follow 
instructions on the WD support page:
https://support.wdc.com/knowledgebase/answer.aspx?ID=3835
(If this works)

As mentioned, I stopped using drives like that. Never did encounter similar 
issues, but then I only used those with MS Windows systems in the past.

My guess is, you unmount the cd-partition, instead of the actual data 
partition. The broken firmware in those drives cause issues with the drivers, 
which is what that "cdrom" partition actually tries to fix.

Best advice: Scrap that drive and get one without the cdrom-partition.

I use WD Elements drives, these don't come with that cr*p.

This is how it works.

To clarify:
The IP-address determines how it is accessible. If the IP is not accessible 
from the rest of the world, then you don't have to worry too much about 
securing your mailserver.

The domain name is only an address-book entry. Unless it is fully entered into 
the public one, noone will see the IP you are using. And as mentioned above, 
even if they can, the IP is sitting behind a router and is most likely in a 
private range.

I build these when I encountered this same issue nearly a year ago. I run them

If it works better, I have no issue with it being pulled in.

Better solutions are always welcome.

 You might technically be able to do it, but I would guess it would

For network devices I tend to use the MAC addresses.

USB devices get a different name if you plug it into a different port.

Since when does the kernel support labels? Last time I checked, you need an 
initramfs to make that work.

In KDE/Plasma there is a scaling setting in the display section. 
The scales go from 1 to 3 (in steps of 0.1)

Seems to work, I don't need it on my displays as I tend to simply increase the 
font-sizes where necessary.

I switched over to chrony some time ago and it actually does what I would 
logically expect ntpd to do.

It's in portage.

Checked the FAQ, blocking by host pattern will work. Blocking by content of the 
page will not.

For blocking ads, this will be sufficient.
If you want to block pages because it mentions cats or other suspicious words, 
https will not work as the data is encrypted.

Not sure about that. But did you check the main page? (www.privoxy.org)
