[Bug 2069305] Re: scp fails to copy files from sysfs
To be complete, I also tried openssh-server_9.3p1-1ubuntu3.3 and see this issue on noble. Which leaves something changed between openssh-client 8.9 and 9.3 to cause this behavior. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069305 Title: scp fails to copy files from sysfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/2069305/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2069305] Re: scp fails to copy files from sysfs
Just for fun, I also tried the latest openssh-client that we have in Jammy and see it works too - # wget https://launchpad.net/ubuntu/+archive/primary/+files/openssh-client_8.9p1-3ubuntu0.7_amd64.deb # dpkg -i ./openssh-client_8.9p1-3ubuntu0.7_amd64.deb # scp root@localhost:/sys/firmware/efi/efivars/BootOrder-8be4df61-93ca-11d2-aa0d-00e098032b8c . root@localhost's password: BootOrder-8be4df61-93ca-11d2-aa0d-00e098032b8c 100% 2027.4KB/s 00:00 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069305 Title: scp fails to copy files from sysfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/2069305/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2069305] Re: scp fails to copy files from sysfs
Thank you for taking the time to make this bug Alfonso! I can reproduce this in a noble-vm very easily. $ lxc launch ubuntu:noble n-vm --vm $ lxc shell n-vm # rm /etc/ssh/sshd_config.d/60-cloudimg-settings.conf # sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config # echo "root:pass" | chpasswd # systemctl restart ssh # scp root@localhost:/sys/firmware/efi/efivars/BootOrder-8be4df61-93ca-11d2-aa0d-00e098032b8c . However it's not just every file in /sys/, there are some files you can still scp. For example: # scp root@localhost:/sys/firmware/efi/runtime . You can also cp the efi variable file and then scp it fine. # cp /sys/firmware/efi/efivars/BootOrder-8be4df61-93ca-11d2-aa0d-00e098032b8c ./ # scp root@localhost:/root/BootOrder-8be4df61-93ca-11d2-aa0d-00e098032b8c ./ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069305 Title: scp fails to copy files from sysfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/2069305/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
