sshd: Too many authentication failures
Using the instructions at https://sonic.software/ to launch the sonic-vs image in QEMU, SSH fails to connect to master and 202405 builds with the following error:
❯ ssh admin@localhost -p 5555
Debian GNU/Linux 12 \n \l
Received disconnect from 127.0.0.1 port 5555:2: Too many authentication failures
Disconnected from 127.0.0.1 port 5555
Comparing the relevant parts of /etc/ssh/sshd_config, it appears that MaxAuthTries is set to too low of a value. If I increase this to 6 (the commented value), or remove the line completely, then it is possible to make a connection.
202311 builds:
# Close inactive client sessions after 15 minutes
ClientAliveInterval 900
ClientAliveCountMax 0
LogLevel VERBOSE
Master and 202405 builds
# Close inactive client sessions after 5 minutes
ClientAliveInterval 300
ClientAliveCountMax 0
MaxAuthTries 3
Banner /etc/issue
LogLevel VERBOSE
I suspect this is a result of the bump from Debian 11 to 12.
It's possible that #99 contains a fix, but I haven't tested the patches to confirm.
[hostcfgd] wrong behavior for disable_feature
In enable_feature:
for suffix in feature_suffixes:
cmds.append("sudo systemctl unmask {}.{}".format(feature_name, suffix))
cmds.append("sudo systemctl enable {}.{}".format(feature_name, feature_suffixes[-1]))
cmds.append("sudo systemctl start {}.{}".format(feature_name, feature_suffixes[-1]))
While in disable_feature, this iteration looks wrong:
for suffix in reversed(feature_suffixes):
cmds.append("sudo systemctl stop {}.{}".format(feature_name, suffix))
cmds.append("sudo systemctl disable {}.{}".format(feature_name, feature_suffixes[-1]))
cmds.append("sudo systemctl mask {}.{}".format(feature_name, feature_suffixes[-1]))
My idea is to change to:
for suffix in reversed(feature_suffixes):
cmds.append("sudo systemctl stop {}.{}".format(feature_name, suffix))
cmds.append("sudo systemctl disable {}.{}".format(feature_name, suffix))
cmds.append("sudo systemctl mask {}.{}".format(feature_name, suffix))
Let's say,
telemetry has feature_suffixes = ['service', 'timer']
enable_feature:
sudo systemctl unmask t.service
sudo systemctl unmask t.timer
sudo systemctl enable t.timer
sudo systemctl start t.timer
=> ok
disable_feature:
sudo systemctl stop t.timer
sudo systemctl disable t.timer
sudo systemctl mask t.timer
sudo systemctl stop t.service
sudo systemctl disable t.timer ?? why do it again
sudo systemctl mask t.timer ??
With new change:
disable:
sudo systemctl stop t.timer
sudo systemctl disable t.timer
sudo systemctl mask t.timer
sudo systemctl stop t.service
sudo systemctl disable t.service
sudo systemctl mask t.service
dhcp has [service]
enable:
sudo systemctl unmask d.service
sudo systemctl enable d.service
sudo systemctl start d.service
=>ok
disable:
sudo systemctl stop d.service
sudo systemctl disable d.service
sudo systemctl mask d.service
=>ok
