dduck's playground for blank html/css like back in the 90s
i could see the handshake failed by the client. the reason was unclear. all solution in the net lead back the reason to a smb1/smb2 problem.
they recommend "allowinsecureguestauth: 1" as a parameter-key in the registry at the lanmanworkstation tree.
the dc give a win7 gpo to the workstation that the "insecureguestauth" is not (more) allowed/unconfigured "AllowInsecureguestauth:dword 0" . this should be ignored by the win10 stations. sometimes a workstation stumbled over this gpo and write this (smb1?)parameter in their own registry. what let the smb2 protocol stumble. the solution in this case, was only to delete the complete key from registry.

no chance to change something or rebuild, all nodes managed by cisco/meraki/veeam. only a little pool of linux boxes.
to monitor this little pool, i installed munin but stumpled over problems with snmp and the nature with the company network. there is no existing dns except the one for winAD.

every file in this folder is part of the plugin configuration no name confess.for printers i build file print.
name of the plugin link what munin-node-configuration did build.
after upgrading from debian 9 to 10 got the start job running for dev disk.
long search different sites not really a solution but a way to go...
lsblk shows the dev and a !new! blkid
the new uuid written in fstab.
then i stumbled about this tiny hit on a site ... comp is encrypted with cryptsetup ... have to change the uuid in a file called "crypttab" too.
changed here => sda6_crypt UUID=abcd123-4567-8901-0101-abcdefg01010101- none luks,swap
After the upgrading the swap got a new UUID and this one was written in the fstab but not in the crypttab.
