weird samba ACLs from MS Office
by Trevor Cordes 10 Jan '23

10 Jan '23

Have samba (4.16) sharing some linux drives to Windows. Want things pretty simple where files on the share are all forced into certain user, gorup, mode: force create mode = 0660 force directory mode = 02770 force user = samba Everything works great. The files get created like this: -rw-rw---- 1 samba samba 0 Jan 4 01:01 test-file.txt ... With every app except MS Office. MS Office insists on making some fubar ACL: -rw-rwx---+ 1 samba samba 50510 Jan 4 01:13 test-excel.csv* #getfacl test-excel.csv # file: test-excel.csv # owner: samba # group: samba user::rw- user:samba:rw- group::rw- group:samba:rw- mask::rwx other::--- Looks like the same thing, eh? But that ACL screws up linus backups as it is stopping a user who is in group samba from reading the file!!?!?? But I don't even want to solve that riddle (because they should be able to read it), I just want to force samba to not let (or just ignore) Office make an ACL in the first place. I don't want any files where ls says "+" in the mode! I swear this didn't use to happen. Might have been years ago, though. All the samba ACL options seem to be to get "more" ACLs. I want less! None! But I don't want to mount the linux fs itself with ACLs off. I just want to force samba to force Office to not be insane. Anyone know the magic for this?

MUUG Online Meeting, Tuesday, Jan 10, 7:30pm -- Taming journald, RTFM: nmap(1)
by Gilbert Detillieux 03 Jan '23

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting online, on Tuesday, January 10th, at 7:30pm: The Taming of journald Continues In his last presentation, Trevor Cordes showed us how to use syslog with journald, and filter out unwanted log lines. However, those bazillion unwanted lines being filtered out are still being written to disk, causing major wear and tear on your precious, limited-life SSD! In this follow-up presentation, Trevor will discuss minimizing SSD writes and wasted space by using the journald RAMdisk and size-limiting options. RTFM: nmap(1) Wyatt Zacharias will give a quick overview of some of the basic features of nmap. This will once again be an online meeting. Stay tuned to our muug.ca home page for the official URL, which will be made available about a half hour before the meeting starts. (Reload the page if you don't see the link, or if there are issues with connecting.) The group normally holds its meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend.
