Hello again. Too all the debain users.
I realised linksys AE6000 wifi usb SUPPORT IS DEAD LOL or maybe im not
checking the right places. Other wise is there a usb wifi that i can buy
That is compatible to debian.

I found that a Realtek Semiconductor Corp. RTL8187B Wireless 802.11g 
54Mbps Network Adapter works real well.
It also has Linux kernel support.  Your best bet is going to be to buy 
from thinkpenguin.com since all they're selling is linux-compatible 
hardware and software and it's how I got this adapter.  That being said, 
this works only on 2.4 band and coming standard will require a 5.0 adapter 
and all of those thinkpenguin.com sold at the time I bought mine needed to 
be bracket mounted internally.  Maybe choices have expanded since then I 
don't know.

I was wondering about that. So you if you download the free and crippled
version, and don't want to pay 7.50 €, you're on your own.

Apparently they like decimal multiples of 7.50 (I'm guessing a lifetime update
and license option must cost 750.00).

My brief visit to the site did not reveal to me the system requirements
for the app; maybe I missed them somehow (or maybe they're not there).

Yes, but before I take a test drive I like to read the manual first.

That looks interesting. The only problem is I'm still using i386 flavor.


Maybe you could try to build from source? The instructions at
https://github.com/therealglazou/bluegriffon
at a quick glance look quite detailed, and I assume you are not
interested in the expensive extra-features from the binary packages
anyway?


Thank you.
The original problem which originally prompted me to investigate
"dpkg -i" has been resolved.

*HOWEVER* your post leads to solving a more important problem.
It has been suggested several times "to build from source". I couldn't
find instructions suitable to my lack of background. The closest I've 
come was working in 8080 assembler ~40 years ago ;} Your reference and 
the educational material at https://www.mercurial-scm.org/ should 
resolve that problem.




Or, the (maybe) easier way, try to pick one of the older releases from
http://bluegriffon.org/freshmeat/ and see if one of these can be installed
and run on your system (2.3.1 appears to be the latest that comes with a
386 deb).

For the record:

   1) My statement above is wrong / misleading.  It turns out that I was

(computer with) the IMAP server (often your ISP).

   2) I should usually refrain from discussions on email, although  I set up a

Max throughput on 1Gb/s ethernet is slightly less than 125 MB
per second. Bits versus bytes, you know.

Anytime you see a rate above that, you're actually seeing
compression ratios rather than on-the-line bytes. Rsync is doing
that for you,

90MB/s is a normalish large-file transfer rate for
not-very-compressible data being read off of a spinning disk.

rsync also makes an awful lot of disk seeks in the attempt to
not transfer data that it doesn't need to transfer.

A gracious response. However, my data were in the context of using a2ps
to go from text to PS. Your "hefty PDFs" would be entirely correct if
paps had been used for the conversion. The result is a 156551 sized file
for me. gs2pdf comes up with a whopping 11540827 and takes 18 s to do so.

That was in 2015, Debian's paps does not relect the existence of a

The most common way to build applications from source on linux systems
uses a "configure" script; the way to build such an app is usually quite
straightforward. 
First thing I usually do is to cd into the source directory and call

$ .configure --help

which will print out a number of available options how the build can be
configured. Next thing is to actually run the configure script with

$ .configure 
followed by 
$ make
and
$ make install
That's it (if all went well)!

One problem that may cause confusion in that procedure is when .configure
stops with an error message saying something like "libfoo not found"
although libfoo is installed. In such a case the solution is to install
the missing header files, usually in a package as "libfoo-dev". 
By default programs compiled like this will install into /usr/local; if
it is desired to neatly separate that app from the system this
can be overridden with configure's --prefix option, as in
$ .configure --prefix=/opt/appname

Some apps of course (as apparently that blue griffon) use a different
approach, so reading the build instructions first is certainly always a
good idea :-)

Surely it depends on your context. If you're communicating over a radio,
then sure, they mean what you mean. But perhaps it's a quotation
(wiktionary states that "over and out" is mostly used in TV and films).
Perhaps it's a reference to cricket (as in "The over is complete, AND

Neither do we. The broken file referred to is basically a program with
subroutines, some external. We don't know what line 576 contains.

The first step would be to copy and paste here that line 576, with two
or three lines before and after it. If the code is inline, we can
probably make some suggestion for improvement, if it refers to a macro
we would need to look a bit further. But with luck, there is an obvious
syntax error on line 576 itself. As the file is autogenerated, it isn't
going to be a typo, but it's probably looking for a variable that isn't
initialised, or something like that. It might conceivably be a typo in
a user configuration file which gets built into this autogenerated one.

I doubt that the exim4 configuration is standard enough that someone
else can find the answer from their own line 576. The version of exim4
I'm running is older and does its configuration differently, so I
can't help directly.

Works fine for txt, although as it rasterizes things it's not going to be
optimized for size.

Yes, typically, but for large fonts and low resolution outputs with few 
pages, rasterised pages may be smaller.

If I feed it a text file, it gives me an error:

convert: improper image header `self_spam.txt' @ error/txt.c/ReadTXTImage/439.

What's the trick to making it work with a text file as input?

I installed and ran iperf, but I don't know whether that provides 
reasonable

results:

Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)

[  4] local 192.168.192.10 port 5001 connected with 192.168.192.20 port 
44282

[ ID] Interval   Transfer Bandwidth
[  4]  0.0-10.0 sec  1.09 GBytes   936 Mbits/sec

When I copy the same file 3 times onto the same share I get an average of
108 MB/s with SMB/CIFS
 84 MB/s with NFS (async,no_subtree_check)

But in many/most comparisons you can find in the internet, NFS is having a
higher performance. So isn't that the case in real worldapplications?

What's the server? Also try 
grep MOUNTPOINT /proc/mounts

(where MOUNTPOINT is /whatever your NFS share is)
you should see either nfs2, nfs3, or nfs4 in the second field, then 
rsize= and wsize= and further down proto=tcp or proto=udp. It would be 
helpful to know what those are on your system.

Anyone can take part. Supporting data is always an advantage,

Anyway, I think I'll abandon my flirtation with paps and return to
something more suitable for efficiently converting text to a searchable

Re: Making a driver for the Matrox P650 card.

Submitted this to their Web based input yesterday.
  One of your P650 dual output PCI cards is here and I wonder whether it 
  can work in Debian 9.  The 1.4.6 and 1.4.7 installer each fails with 
  an error message.   Any chance of either case being resolved?

  The log is rather long in each case.  I won't try to impose it here.
  
The reply is essentially a duplication of the information from  
their Web site.  
"For the P650, those are the supported distributions:
- Red Hat Enterprise Linux 4 WS (updates 7 and 8)
- Red Hat Enterprise Linux 5 WS (updates 2 and 3)
- SuSE Linux Enterprise Server 10 (sp2)
- SuSE Linux Enterprise Desktop 11
- Fedora 10
- OpenSuse 10.3 and 11.1
- Ubuntu 8.04 and 8.10"

 And "... try using one of those distributions."  I won't be 
installing Ubuntu 8  to make an old video card work but still wonder 
how far a driver which  makes in Ubuntu 8 is from making in Debian 9.  
If anyone has a tip to  resolve the failure reported in my preceeding 
message, please let me know.
 
Thanks,  ... Peter E.

I would initially forget about what your link advises and set up exim
per the Debian documentation to get reliable sending and receiving of
mail. Then I would add the rest in.

We could hazard a guess though. Mine would be that the OP tried
to put multiple smarthosts, say, by connecting them with AND rather
than ";".

But I would ask that the OP post their /etc/exim4/update-exim4.conf.conf
in the first instance, suitably recused of course.

Debian stable Mate wifi work but don't connect

I just tested after an issue was reported to confirm it, the mate live
iso has an issue with wireless, the first user is fairly unexperienced
and I'm fairly skilled as a linux community manager but uncertified
for Linux [sysadmin] (tried twice on my case).

On my system, Lxde live iso work perfectly so it could be a
misconfiguration of Mate, the drivers don't seem the issue.

The first system was also checked by a programmer that don't found
anything suspicious, the drivers is there but it don't work.

One more distracting error... :-)


Surely it depends on your context. If you're communicating over a radio,
then sure, they mean what you mean. But perhaps it's a quotation
(wiktionary states that "over and out" is mostly used in TV and films).


The reason it's mostly used in TV and films is that the writers don't 
know any better.  Or they're pandering to viewers don't know any better. 
 But it is not, and has never been, proper procedure for anyone who 
uses a radio in real life.


And don't call me Shirley.


Perhaps it's a reference to cricket (as in "The over is complete, AND
the batsman is out").


An interesting back-formation...

What a delightfully distracting error this is turning into!

The server is a self-built machine with an ASRock J4205-ITX mainboard, 
8GB RAM, a Samsung 470 SSD as system disk and 2x WD Reds as data disks. 
It's running the Debian backport kernel 4.13 (4.14 since yesterday).

Re: Printing problem Sadly NOT SOLVED

[arne]

This printer Brother HL-L2340DW has buggy firmware.

When re-installed it killed my CUPS.
.

I can no longer use my local CUPS webpage, my root/admin password is not
accepted.

I instead use system-config-printer, which runs fine.
Thanks to this program I can at least print as root.

But I cannot recommend Brother

On my second PC it runs OK, I never installed it here, just now after
the fiaso on my main PC.

So my hint is: never change a running system!

 The Japanese at Brother just want to sell more printers, at least,
 that is my assumption.

Have a good New Year!

PS never update your Brother laser printer and never buy them.
