Re: [PLUG] Firefox 127.0 uploading files via web
On 6/25/24 13:01, Russell Senior wrote: Hi, I had a slightly bizarre experience yesterday with Firefox. I was using a web form to upload firmware to a router. The classic "Browse" button allowed me to navigate my local environment for a file to upload and "Select" the file. Because the file was actually coming from another machine, I had scp'd it to my local /tmp directory to make it available to my browser. So, I navigate to /tmp/, see the intended file, and click "Select" in the file browser. But then, the file isn't actually selected, and there is nothing to upload when I click the Upload button in the web form. I thought to myself, "wait, what?". So, I copy the file to my ~/Downloads directory and try again and it works. I try in a private browser window. I try in Firefox's "Safe mode" (or "Troubleshoot Mode"). Still, it works from ~/Downloads but it does not work from /tmp or /srv/randomdir. I checked ownership/permissions of the file and the directory. This is on a fairly recent install of Ubuntu 22.04, with Firefox 127.0.1, and the default Snap. Does anyone have insight to this odd behavior? And to add insult to injury, on my near identical setup, it "works for me". Strange, very strange. galen -- Galen Seitz gal...@seitzassoc.com

Reliability should be quite high, but you could always be the unlucky one. I.e., if your data is not backed up, your data doesn't exist. I think the reliability of Crucial, Intel, and Samsung are all likely to be quite good. One thing I would suggest is to be sure the disk has the latest version of firmware before you start moving or installing data on it.

[PLUG] newegg security
Hi, Yesterday I went to the newegg web site to buy a disk. I opened a private browsing session in Firefox and went to newegg.com. I then clicked on the login link on their home page. At this point my memory gets a bit fuzzy, but I believe it was at that point I got a "Your connection is not secure" page from Firefox. At that point I followed a link from the Firefox page to the SSL Labs' test page. I ran a test on secure.newegg.com and it came back with a grade of F. Unfortunately I subsequently closed the firefox private session, losing the test information and the IP address. This morning I tried the SSL test again on secure.newegg.com, and the resulting score was A+. Now I'm left wondering what was going on yesterday. Has anyone else encountered this? I *really* wish I hadn't deleted that page with the F score.

Generally modes are associated with filename endings, so .c or .h are
associated with c-mode, .py with python-mode, etc. To make this
association, the mode is added to auto-mode-alist. For example:
;; Any files that end in .v, .vh, .sv, or .svh should be in verilog mode
(add-to-list 'auto-mode-alist '("\\.s?vh?\\'" . verilog-mode))

Actually I'd say there's a snowball's chance that a manual even exists, much less getting a hold of one. Then there's the potential language issue. Assuming you're comfortable working on this and know enough to stay away from the AC supply ... sorry, I should have noticed the call sign earlier. That probably means what I'm about to suggest is what you would have done anyway. Pull the rear cover. Find the audio amp if you can. Presumably it's an integrated class D amp. Post the part number here if you find it. Look for a datasheet. If you can find one, consider that a minor miracle. Feed an audio signal into the monitor. My preference would be the 3.5 mm jack. Probe the audio amp, looking for the line level audio. Check the supply pins too. Discover that the amp is dead. Order a replacement part. This is where the major miracle occurs.

First confirm that it truly is broken by trying it with another device *and* cable that are known to work. I see that it has a line-level 3.5 mm jack. I would definitely try feeding it an analog audio signal through this jack. Alternatively, you could try the audio RCA jacks. This should tell you whether the audio amp itself is broken, or whether the problem lies somewhere upstream. Not to insult you, but you should also confirm it's not muted. Even if the on-screen display doesn't indicate it, I'd toggle the mute button a few times. Finally, I also suggest disconnecting power for a minute or so and then reconnecting.

The USB to ethernet market is dominated by a semiconductor design house called Asix, with Realtek making up most of the rest. Microchip also makes a USB to ethernet adapter, but it seems to be nonexistent in the retail market. Regardless, whatever you buy won't have these names on the package. In the fine print on the back you might find a part number like AX88772. This is a 100 Mbit Asix device that is very common and is definitely supported by Linux. I have one that was sold by Monoprice, but I don't see it on their web site now. Anyway, the short answer is that Linux has decent support for USB to ethernet adapters. My guess is that any 100 Mbit adapter that you find will be supported. 1 Gbit adapters are more questionable due to their newness.

Thanks! That was indeed the problem. I now have my rsnapshot package
installed under CentOS 5.
There is a perl script in the rsnapshot doc directory that uses perl DBI
and XML modules. Some searching suggests that under Fedora it is
forbidden to generate requires/provides based on the contents of
%{_docdir}. Apparently that does not apply to CentOS 5 or 6, because
packages built there pull in DBI and XML perl dependencies. I don't
have a CentOS 7 machine, so I'm not sure about that environment.
<https://fedoraproject.org/wiki/AutoReqProv_%28draft%29>
Regarding the Lchown module that Dale mentioned, yes, that is also
dependency. I back ported a recent Fedora release of that package in
order to get it.
Also, I generally follow Ali's advice and avoid installing anything
beyond CentOS and epel packages.
Thanks to everyone for their help.

[PLUG] unexpected perl dependencies
Hi,
I'm encountering dependency problems while trying to install an rpm
package that I built. The program is rsnapshot, which is a perl program
similar to dirvish.
I've got it working under CentOS 6 and Ubuntu 16.04 (using alien), but
I'm having problems with CentOS 5 due to missing dependencies. The rpm
I built under CentOS 5 has the following problematic dependencies. As
far as I know, these dependencies are not readily available under CentOS
5. I could build them if that's really necessary, but I have my doubts
as to whether they are legit.
perl(DBI)
perl(Data::Dumper)
perl(XML::Simple)
perl(XML::Validator::Schema)
I've searched the rsnapshot code looking for something that mentions DBI
or XML, but they don't appear in the code. They do not appear in the
spec file either. Also, the rsnapshot README says "It is written
entirely in perl with no module dependencies". I'm not sure whether to
believe that or not.
Does anyone have an idea about what might be causing these dependencies
to be listed in the package?
Here's the spec file I'm using, sans the changelog stuff.

%description
rsnapshot is a filesystem snapshot utility for making backups of local
and remote systems. Using rsync and hard links, it is possible to keep
multiple, full backups instantly available. The disk space required is
just a little more than the space of one full backup, plus
incrementals. Depending on your configuration, it is quite possible to
set up in just a few minutes. Files can be restored by the users who
own them, without the root user getting involved. There are no tapes to
change, so once it's set up, you may never need to think about it
again.

Beating a very old horse here, but I've been intending to respond to
this. The reason these commands are failing is that redirection ('>')
is performed by your original shell, not sudo. Your rsteff account
doesn't have permission to write to files in the /proc directory, hence
the error. Others have shown that you can just get a root shell and
then issue the echo command, but I wanted to point out that you can do
this from a single command.
This command invokes a root shell and then passes the desired command,
including redirection, to that shell.

It took at least 10 minutes to get to the screen that allows selecting between Live and Install. Knoppix boots in one tenth the time or less. Is this normal? Is there something I can do to speed it up? thanks, galen -- Galen Seitz gal...@seitzassoc.com ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

If that's DSL as Russell suggests, you should know that your upload speed is likely limited to 800 kbit/s, or perhaps double that if they do bonding on the upstream path too. Regarding bonded DSL, I will just comment that my neighbor signed up for this a couple of years ago, but CenturyLink could never get it to work.

Stuff you build yourself generally goes in /usr/local, and third-party applications generally go in /opt. For example, I have electronic design tools from companies like Altera, TI, and Xilinx. I install their software under /opt. Because I can almost always find packages(rpms) for the other stuff I need, my /usr/local happens to contain only one tool that I built myself.

This lack of understanding is because I do not have a > clear view of what happens when a device is mounted, and how the device is > accessed without mounting. When a filesystem is mounted, the linux will typically cache blocks of filesystem data in RAM for performance reasons. Blocks of data that need to be written back to the device (aka dirty blocks) may sit in RAM for multiple seconds before being flushed to the device. This is one of the reasons that graceful shutdowns are always preferred over pressing reset or yanking the cord. In the case of a floppy or USB drive, ejecting or unplugging is the equivalent of yanking the cord. There is no opportunity for the system to write the data to the device, and filesystem corruption is often the end result. AFAIK, the mtools commands don't do any caching of writes. When you get the next command prompt after executing an mtool command, it is safe to immediately eject the disk. As described above, this is not true of a mounted filesystem. Hope this helps. galen -- Galen Seitz gal...@seitzassoc.com ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

Hi Guys,
I thought I'd try a local resource. I have a Fedora 21 and an OSX 10.10.5

find through google searches on the subject, and it appears I have smb and
nmb running on the Fedora box, but nothing is showing up in the network

I had initially tried an AFP server using netatalk, and with that I could
see the linux machine from osx. But connecting to it failed. Apple is also
moving away from AFP for file sharing apparently:
http://appleinsider.com/articles/13/06/11/apple-shifts-from-afp-file-sharing-to-smb2-in-os-x-109-mavericks
So I removed netatalk and am attempting to go with samba.
The smb and nmb services are running, but something doesn't look quite
right:
hobgoblin:~:{928}service nmb status -l

Have you confirmed that your network interface is up and running? Can
the Fedora machine ping the OS X machine?
Assuming you have network connectivity, what is the name of your
ethernet interface? eth0 or something else? You can use ifconfig to
list your interfaces. Does it match your interfaces line in
/etc/samba/smb.conf? I'm not sure how samba decides which interfaces to
use if they aren't explicitly listed, but a search shows someone curing
this problem by specifying his interface.

galen,
OK. Here's an example row:
'B',1992-03,Cl,4
and what I want is to convert it to:
'B','1992-03','Cl',4
The regex I tried to quote the year portion of the date:
,\([:digit:]\{4\}-[:digit:]\{2\}\) RET ,'\1
did nothing. The plan was to do one chunk at a time because my regex skill
is not sufficient to do it all in one step.
To quote whatever is in the N+1 CSV column:
search: ^\(\([^,]*,\)\{N\}\)\([^,]*\)\(,.*\)
replace: \1'\3'\4
This won't work if you are trying to quote the first or last column, as
it expects ',' surrounding the thing you are quoting.

Everything leading up to the stuff you want to quote goes in the first

Match N occurrences of anything followed by a comma. Anything
followed by a comma is the second group. This group is needed in order

Match anything that's not a comma and put it in the third group.

They sometimes overlap with the existing ones (which I didn't alter), but I'd rather have a bad log entry match twice than not at all. Bottom line: I'd suggest comparing the log entries that weren't matched with the regex code in DenyHosts. Belated thanks, Paul. I've finally gotten back to this. I installed fail2ban this morning. After an initial misconfiguration (sending the ban notifications to example.com), I think it's now running properly. What is somewhat interesting is that denyhosts is now blocking some of the same hosts as fail2ban. I have no idea why installing fail2ban would cause denyhosts to start working again. Perhaps it noticed the competition and decided to start doing its job.
