I took a nap, after doing today what I used to do on Friday, which involves going to Doctor, getting shots, then shopping around town etc etc. Anyway, I woke up to Qbittorrent being gone. It crashed at some point. In the notification thingy, it had a few of the file open errors again. So, I ran some of the commands you posted, my hard limit was set to 4096. I whipped out my calculator and doubled it. I set it in the limits.conf file like so: root@fireball / # cat /etc/security/limits.conf | grep nofile # - nofile - max number of open file descriptors * hard nofile 8192 root@fireball / # I logged out and back in. I ran the command you shared and it was indeed set to the new amount. I'm going to upgrade qbittorrent to the new version again and test it some more. Thanks much for the help. Maybe this will fix it. Dale :-) :-)
Re: [gentoo-user] Getting printer working, the road of Pain.
Hello Alan,
(meanwhile, Windows can print to the thing effortlessly)
I guess, that you are going to configure a network printer.
I will try to explain you my setup; maybe you or others can derive
something from this.
Make sure, that the user, which you configure the printer with, is a
member of the group "lpadmin":
$ gpasswd --add lpadmin
$ getent group lpadmin
lpadmin:x::
On the server-site, the configuration file "/etc/cups/cupsd.conf" should
be configured like so. See comments for explanations:
# Only listen for connections from the local machine.
Listen localhost:631
# custom - 20210706 - rfischer: set custom listen address to
"192.168.1.80" to make it available via the network
Listen 192.168.1.80:631
Listen /run/cups/cups.sock
# custom - 20210706 - rfischer: make cups available via "hostname"
or "domain"
ServerAlias *
# Restrict access to the server...
#
# Order allow,deny
#
# custom - 20210706 - rfischer: allow access from "localhost" and
via the network
Order allow,deny
Allow localhost
Allow from 192.168.1.*
# Restrict access to the admin pages...
#
# Order allow,deny
#
# custom - 20210706 - rfischer: make administration page available
via the network
Encryption Required
Order allow,deny
Allow localhost
Allow from 192.168.1.*
Restart the daemon on the server-site:
$ systemctl restart cups
This will also restart the Systemd socket unit "cups.socket" and
"cups.path".
Make sure, that CUPS is running on "192.168.1.80:631":
$ ss -tulpan | grep "631"
tcp LISTEN 0 5 192.168.1.80:631 0.0.0.0:*
users:(("cupsd",pid=2190,fd=8))
tcp LISTEN 0 5 127.0.0.1:631
0.0.0.0:* users:(("cupsd",pid=2190,fd=7))
tcp LISTEN 0 5 [::1]:631 [::]:*
users:(("cupsd",pid=2190,fd=6))
If printing via hostname is desired, you can add the following entry for
your local DNS server:
192.168.1.80 cups.intern
This Forward DNS lookup entry can also be entered on the client-site in
the configuration file "/etc/hosts".
Your CUPS isntance should be now available via "cups.intern:631". There
you should be able to configure your printer.
I configured the server-site via USB:
usb:/?serial=
In the best case, CUPS already has a pre-installed printer driver or you
have a PPD (PostScript Printer Description) file, which you can upload,
when adding the printer.
Once configured, the directory tree of "/etc/cups/" on the server-site
should look like this:
$ tree -ugp --noreport --charset iwantprintableasciiplease /etc/cups
/etc/cups
|-- [-rw--- root lp ] classes.conf
|-- [-rw-r--r-- root root ] cups-browsed.conf
|-- [-rw-r--r-- root root ] cupsd.conf
|-- [-rw-r--r-- root root ] cups-files.conf
|-- [drwxr-xr-x root root ] interfaces
|-- [drwxr-xr-x root lp ] ppd
| |-- [-rw-r- root lp ] .ppd
|-- [-rw--- root lp ] printers.conf
|-- [-rw-r--r-- root root ] raw.convs
|-- [-rw-r--r-- root root ] raw.types
|-- [-rw-r--r-- root root ] snmp.conf
|-- [drwx-- root lp ] ssl
| |-- [-rw-r--r-- root root ]
.crt
| |-- [-rw-r--r-- root root ]
.key
`-- [-rw-r- root lp ] subscriptions.conf
Since I do not want to install the printer driver on every client and
let the clients render the pages, I want to let the server handle these
things.
On the client-site (localhost:631) therefore, I can just add the printer
via "http/s" or "ipp/s" and transfer everything either via "IPP
everywhere" or "raw":
ipps://cups.intern:631/printers/
Be aware, that "raw" is deprecated and newer versions of CUPS will
remove it. So "IPP everywhere" would be the choice, but I stick to
"raw", since the former shuffles print jobs for some reason, when I want
to print multiple files via "lpr " on either
the client- or server-site.
You should now be able to print a test page on the client- and server-site.
Much success and a pinch of luck! :)

Who needs to go to the hassle maintaining a printer of their own, buying cartridges, paper etc? I set up an online account at my neighborhood Kinkos, and I just upload whatever docs I need and they print out in HD whatever I need for pennies a page. Ymmv.

You'll need the right drivers for the printer you have. This page is a good start for CUPS and usually it doesn't take long to connect to the printer and start printing. https://wiki.gentoo.org/wiki/Printing Modern printers invariably offer their own http(s) web GUI for administration, which may also need configuring, but just printing alone should be achievable by using the guidance in the wiki above. signature.asc Description: This is a digitally signed message part.

It's not bad at all if you use a distribution with a better default configuration, pre-installed drivers and a pre-installed GUI for setting up the automatically detected printer in less than 5 clicks. Unless you have a printer from a shitty company, of course.

But this is max files for kernel, which is different for max files per user and max files per process. For example if I run: $ grep 'Limit\|open' /proc/$(pgrep qbittorrent | head -1)/limits Limit Soft Limit Hard Limit Units Max open files524288 524288 files 524288 = 2^19 QBittorrent increases it's process limit to hard limit. With 10 TB of torrents it's hard to tell if it's a bug or just 500k files is not enough, I'd say it's probably the latter. It seems you can change the default hard limit in /etc/security/limits.conf For example: # 2^24, increased from 2^19 * hard nofile 16777216 Then after reloging: $ grep 'Limit\|open' /proc/$(pgrep qbittorrent | head -1)/limits Limit Soft Limit Hard Limit Units Max open files16777216 16777216 files So this works, at least for me. Check also limits.conf man page. Regards, mmokulus
