Vim shifty comment behavior
by Chris Miller 09 Feb '23

09 Feb '23

Hi Folks, When I comment out a line, vim left justifies the line, but I want the indentation to say exactly where it is! Does anybody now when vim setting is responsible for either 1) Causing the shifty left justification of comments, so I can delete it 2) Suppresses this shifty left justification that is maybe part of some other setting, which maybe does things I want. I just want it to stop! (-: Thanks for the help, -- Chris. V:916.799.9461 F:916.974.0428 A: Because we read from top to bottom, left to right. Q: > Why should I start my reply below the quoted text?

Mount owner and pemissions
by Chris Miller 27 Jan '23

27 Jan '23

Hi Folks, If I mount a remote share with CIFS, then I can specify the UID and the GID and the UMASK of the files in the paths below the mount point, but these do not reflect anything for the file in its native filesystem. I see gazillions of questions about this, all of which are answered with the tactical answer about UID, GID, and UMASK necessary to let the original poster get on with the limited access they need. There are almost as many postings claiming that CIFS has no other permission/ownership model beyond these global settings. So, my question is, "Do I have any other mount options?" I want to backup large chunks of my system with "rsnapshot", which is an "rsync" between the stuff to backup and the destination NAS. I need to preserve ownership and permissions, not to mention "case" and "rsync"ing to a CIFS (SaMBa) share is not going to do it. If I "tar" everything, I do preserve file meta data but I pay a penalty in time and space to make copies of relatively static content. Thanks for the help, -- Chris.

Case insensitive filesystems
by Chris Miller 26 Jan '23

26 Jan '23

Hi Folks, I have three NASs: two Buffalo Link Stations, and one ASUStor. It never occurred to me to check for case insensitivity before, but I did and they aren't! This surprises me because case sensitivity is much easier to implement and it does not surprise me because the Windows world is case insensitive. So, my first question is, "Can I require case sensitivity during the mount command?". I can't find anything about that, but I have seen comments claiming that CIFS mounts are case sensitive by default, but mine clearly aren't. As an ancillary question, does anybody know if btrfs is case sensitive? I've spent some time looking, but I haven't found any comments I trust. For example, the [ https://en.wikipedia.org/wiki/Btrfs | Wikipedia article ] fails to mention it. Thanks for the help, -- Chris.

DNS problem
by Chris Miller 19 Jan '23

19 Jan '23

Hi Folks, O.M.G.! I have spent all afternoon trying to diagnose a DNS problem that presents like corruption but I can't find any trace, beyond the failure that I think is the result. This is a Windows Server problem... I have a domain name for my NAS -- "\\NAS0.TCLC.org = 10.1.1.80", and all evaluations show me that translation. I can ping it; I can nslookup; I can run the DNS management application. My linux machines can "mount //NAS0.TCLC.ORG/d0 /net/nas0/d0 ..." All work exactly as you'd expect. Then I try to view the share with the Windows File Explorer -- "Windows can't find the DNS name"!! In that case I can use the IP address directly or the alternate domain name, so it is the domain name on the windows machines that is the problem, not the disk access protocol. I also created a second domain name "\\NASX.TCLC.org = 10.1.1.80" and that one work just fine everywhere! Here I tried the command prompt: C:\Windows\system32>net use n: \\10.1.1.80\d0 The command completed successfully. C:\Windows\system32>net use n: /delete n: was deleted successfully. C:\Windows\system32>net use n: \\NASX.TCLC.org\d0 The command completed successfully. C:\Windows\system32>net use n: /delete n: was deleted successfully. C:\Windows\system32>net use n: \\NAS0.TCLC.org\d0 System error 64 has occurred. The specified network name is no longer available. Of course I have flushed all caches I can find, scavenged resources records, rebooted every element -- Windows DNS server, Windows Server 2012r2, NAS, Client, ... the toaster and the microwave! So, I have a domain name that shows zero problems in any investigation, until I try to use it for its intended purpose on the windows machines , and I have another one that is nearly identical that has no problems! Any thoughts? Thanks for the help, -- Chris. V:916.799.9461 F:916.974.0428

Hi Linus, > Did you say it all worked fine by ip address? Windows PowerShell: $ nslookup nasx.tclc.org -- works. Reports 10.1.1.80 $ nslookup nas0.tclc.org -- works. Reports 10.1.1.80 # mount //10.1.1.80/d0 /net/nas0/d0 -- works # mount //nasx.tclc.org/d0 /net/nas0/d0 -- works # mount //nas0.tclc.org/d0 /net/nas0/d0 -- works > dir \\10.1.1.80\d0 -- works > dir \\nasx.tclc.org\d0 -- works > dir \\nas0.tclc.org\d0 -- fails If I change nas0.tclc.org to a different IP, say 10.1.1.81, then dir \\nas0.tclc.org\d0 still fails. So, any inspection of nas0.tclc.org works everywhere, but any use of nas0.tclc.org fails only on Windows , regardless of the value. I no longer suspect a corruption, since I have purged and reinitialized all known sources and caches. This may be a collision, but that would require some rogue assignment that I haven't found. It may also be a permissions problem, but domain name level permissions is easily checked and I compared this name with nas1.tclc.org, which is not known to have problems. Ultimately, the culprit will have to be the NAS, since this all happened, coincidentally, after a system update. I have review all the settings for the NAS, and I have found nothing.

Hi Linus, The full story is that I applied an update to this NAS just before this foolishness, so I have every reason to believe that is the culprit, but even knowing this, I am unable to diagnose the problem. Especially given that only one domain name has a problem -- "NAS0.TCLC.org". It is clearly the domain name, not the device; a different domain name (NASX.TCLC.org) works just fine. And the same domain name fails regardless of the IP. 'arp -a', look ok? Should clear at reboot but I've seen stranger things. Is there anything in hosts besides localhost entries? Does the output of the hostname command match the address record? nslookup the address of your machine and see if it's the only entry for it, is this the only interface live? When I first started to investigate this, I found a bogus DNS entry defining NAS0.TCLC.org as 10.1.1.103 and DHCP told me that this was the address of ASUSTOR-3204T.TCLC.org, which, as you can guess, turned out to be the NAS. I deleted this and cleaned up DNS and DHCP and I have eradicated 10.1.1.103 from the system. I also have no reason why the NAS was asking for an IP. I'm going to chalk it up to some sort of update semantics, because the NAS is configured with a static IP and a DHCP reservation. All of your proposed diagnostics return exactly what you would expect. arp, nbtstat, nslookup, ping, ... I have even disjoined and rejoined the domain. So far, nothing has had any effect. From windows PowerShell on any windows machine in the domain: * dir \\10.1.1.80\d0 -- works * dir \\nasx.tclc.org\d0 -- works * dir \\nas0.tclc.org\d0 -- fails From any Fedora machine, "mount //NAS0.TCLC.org/d0 /net/nas0/d0 ..." works. So, it is only Windows, and it is only "NAS0.TCLC.org". Any other combination works. This is truly bizarre. I hope it does not simply vanish as quickly as it appeared; I really want to know what is causing this. Thanks for the help, -- Chris.

It's That Time!!
by Linus Sphinx 27 Dec '22

27 Dec '22

So been about 3 months since I handed a dell E6400T laptop loaded with fedora 36 booting up to the welcome screen waiting to finish the install to senior citizen neighbor who couldn't support windows 10, asked me two days later if it was safe to do his banking on, "all I ever use", I answered along with an expression of deep gratitude for the gift that was his only question. "Just keep it up to date whenever it prompts for it", and I haven't heard a peep since. With apologies to Bing Crosby; "It's beginning to look a lot like the year of linux desktop".

Deploying FTP on IIE
by Chris Miller 16 Dec '22

16 Dec '22

Hi Folks, I want to deploy an FTP server on my Windows Server 2012r2, which is a component of Internet Information Server. Initially, I had the obvious and simple problem of the firewall blocking access to port 21, but I think I fixed that. It was a little tricky because the port was an artifact of the FTP service , not the IIE FTP component, so it took me longer than I would like to admit. Now I have the problem of authenticating. Can't seem to authenticate. Has anybody done this? Thanks for the help, -- Chris. V:916.799.9461 F:916.974.0428 A: Because we read from top to bottom, left to right.
