Question about stderr output containing carriage return External
...de, \n is not the line separator but \x0D\x0A is: \x0D moves the cursor to the beginning of the line and \x0A moves it to one line below but does not change the horizontal position. So it?s a requirement when in raw mode and doesn?t hurt in cooked mode. bye, //mirabilos -- Infrastrukturexperte ?

Hi Josh, it's been around for a while: https://github.com/openbsd/src/commit/8747197a4a479407167d01f46017ddb99cc3cae2 Though the commit doesn't say why it needs the \r.

An Analysis of the DHEat DoS Against SSH in Cloud Environments
I'd like to withdraw the last set of metrics I reported. I couldn't reproduce some of them, and I suspect I made a mistake during testing. Being more careful this time, I set up another fully updated Ubuntu 24.04 VM with 4 vCPUs running openssh-SNAP-20240628.tar.gz with all defaults unchanged. When running using "ssh-audit.py --conn-rate-test=16 target_host", the system idle

The problem, from my Yes, but if the reason behaviour under DoS is that logging is too slow and/or uses too much CPU, the fix is not to remove logging in the default configuration. bye, //mirabilos -- Infrastrukturexperte ?

Can we reset CSI u mode on client disconnect? via
ssh already restores all TTY flags on exit: https://github.com/openssh/openssh-portable/blob/V_9_8_P1/sshtty.c#L56-L78 It's possible there are some exit cases that are not hitting the leave_raw_mode(), but if so then they aren't obvious.

I managed to do some limited testing with a local VM, and the results are... interesting. I installed openssh-SNAP-20240626.tar.gz on a fresh and fully-updated Ubuntu Linux 24.04 LTS VM with 1 vCPU.
