This is... surprising. If I were you, I'd look around in the current
directory whether there's a file named `sudo' with an "1" in it.

Thanks for the clarification. `echo 1 > sudo /proc/sys/vm/drop_caches`

Right.  My phrasing could have been better; I was thinking "stable"
gets updated about every two years, but testing => stable is more of a
replacement than a migration.

The kernel module intel_ips floods the logs

[Darek Hisc]

After disabling Intel ME in the laptop BIOS, the kern.log began to be flooded 
with thousands of such entries (approximately every 0.5s):
$ dmesg
intel ips :00:1f.6: ME failed to update for more than 1s, likely hung

On some forum I found this advice:

1. add intel_ips to the blacklist
   echo "blacklist intel_ips" >> /etc/modprobe.d/blacklist.conf
2. add i915 and intel_ips to /etc/modules
   echo -e "i915\nintel_ips" >> /etc/modules

I only made the first point and the log flood was over.


Two questions:

1. Could disabling the intel_ips kernel module completely have harmful 
consequences for Debian 11?
2. What's the point of the advice in step 2 to first add intel_ips to the 
blacklist and then re-enable it in /etc/modules? Does it make sense?


Cheers!

That is why I hate IPv4. With IPv6 there is not NAT necessary and if
ULA is implemented correctly (random bits), almost no collision occurs.

They may collide, but it is not a real problem, because it only affects
the situation when 2 sites are connected together.
Using random bits avoids such a situation, but if they collide, one
of the networks must be changed.



Exactly. The same happens when connecting two sites using ipv4.
Renumbering is often a pain, to the extent that I worked somewhere where
there was natting between the two companies so that the other company
looked like it had different IPs to what it really did and DNS was
horrendous! Cached dns for someone moving between the sites was a
problem...

All because the same 10.x addresses had been chosed and renumbering one

Salve Massimo :)

I'd suggest asking specifically on the debian-live list - things have changed
relatively recently, I think.

It's also worth reminding people in general that the debian-live images are
*not* maintained by the debian-cd team but just released by them with minimal 
testing.

All the very best, as ever,

Andy Cater 

Debian live iso on usb returns grub

[Massimo Maiurana]

I've downloaded the latest iso with testing weekly build, both with and 
without firmwares, and wrote them on a usb stick (of course one at a 
time) but at boot it doesn't start the installer. It boots but all i get 
is the grub comman line.


From that command line i can boot the installer with the following 
commands but looks to me like it is a sort of bug, just don't know how 
to report it so i'm writing here:

grub> linux (hd0,msdos1)/install.amd/gtk/vmlinuz root=/dev/sdb1
grub> initrd (hd0,msdos1)/install.amd/gtk/initrd.gz
grub> boot

Now it stops in the step where it tries to detect hard drives. The 
message returned, translated from italian, is more or less this:

>Loading libc6-udeb failed for unknown reasons

Do you have some advices?

To add another one, I like dd for that one (it doesn't clutter
stdout unnecessarily).

  echo 1 | sudo dd of=/proc/sys/and-so-on

Embarrasment of riches!

Basically, what one is looking for is a cat one can pass an
output file name as a command line argument -- or put another
way, a cat which opens its output itself.

Unfortunately, it's your current shell and not root who does the
redirection in this case so no permissions.

For a longer explanation see

Because the output redirection occurs as your normal user, all you are
doing is executing the 'echo 1' command as the superuser.

They may collide, but it is not a real problem, because it only affects
the situation when 2 sites are connected together.
Using random bits avoids such a situation, but if they collide, one
of the networks must be changed.

IPv6 ULA isn't being used for internet traffic, it is intended for
traffic within a site, like company network or a home network.

If 2 companies use IPv6 ULA with random bits, the probability of a
collision is very low if they now interconnect their networks via a
direct connection (without internet).

Internet traffic uses 2000::/3 and fd00::/7 must not be used for
outgoing traffic.

AFAICT the rest of your post is concerned with global IPv6 addresses
rather than local (ULA) ones, which is why the prefix for the home
LAN has to be given to you rather than generated/assigned by yourself.


It is possible to use an additional ULA at home to address computers.
This ULA can be taken to a new provider because it is only valid inside
your network - not on the internet.


Sure, and if Curt had quoted two paragraphs about ULAs instead,
I would have pointed out that the user-generated pseudorandom
global ID within them means that they too are unlike local
IPv4 addresses, ie not fundamentally identical.

A consequence of IPv6 ULAs having a global ID is that it should be
straightforward to merge a number of local sites with independently
assigned addresses, without causing any collisions.

Perhaps that clarifies what I took from Curt's use of the term
"fundamentally identical" with respect to IPv4 local addresses.



Isn't the danger here that everybody starts using fd00::/64. Even for
ipv4, the odds of two sets of private addresses colliding should have
been small...

I know there's an RFC for avoiding this but I'll be pleasantly surprised
if it's widely followed as ipv6 starts taking over the bulk of internet
traffic for everything.

Clearing RAM Caches

[Timothy M Butterworth]

When I run `sudo echo 1 > /proc/sys/vm/drop_caches` I receive the following
error: bash: /proc/sys/vm/drop_caches: Permission denied

I have `%sudo   ALL=(ALL:ALL) ALL` in my /etc/sudoers file. All commands
should be allowed for group sudo.

ls -la /proc/sys/vm/drop_caches
--w--- 1 root root 0 Aug 14 16:28 /proc/sys/vm/drop_caches

I tried adding group permissions with `sudo chmod 440
/proc/sys/vm/drop_caches` and receive the following error message chmod:
changing permissions of '/proc/sys/vm/drop_caches': Operation not permitted

If I run `sudo sh -c "/usr/bin/echo 1 > /proc/sys/vm/drop_caches"` it
works.  Why does  `sudo echo 1 > /proc/sys/vm/drop_caches` not work, so
frustrating.
