[SLUG] Associating filenames

[Howard Lowndes]

Is there any ability in Linux to associate filename extensions, or 
similar, with applications.  I have been fiddling with Staroffice and 
that works OK, but I am curious as to whether the ability exists in 
Linux on a broader basis, more to do with such associations in 
Netscrape.

Howard who hasn't got his .sig working in Staroffice yet

No, that's regarded as userland stuff so it's done on a per-manager
basis by file managers and browsers. This is arguably a weakness of the
Unix filesystem model, it delegates these issues to applications.
Although Linus has said that he would like to see support for multipart
files a la Mac's forks. This is actually stronger than matching by
extension, it effectively creates file typing.

Where are you making the associations (or want to)?

File managers such as GMC, Nautilus and EFM will do this for you as part of
their mime support, usually using magic2mime (and related utilities or
libraries).

  Here's yet another area where the MacOS had us in 85. Intrinsic metadata.
  DOS/Windows had easily human-stuffupable "metadata" with file extensions,
  UNIX has nothing (apart from what the file appears to be). BeOS however,
  has a very, very heavy focus on metadata (the filesystem is designed to
  have almost unlimited metadata extensibility).


With Linux, you either rely on your applications (generally the file manager
types), or have to work it out yourself.

most unix programs that need to do these sorts of things do it through
mime types. and if they don't, then they should.


extension - mime type mapping is done by /etc/mime.types (extensible
through ~/.mime.types). web pages, email attachments, etc already have
the mime type given, so they don't need to do this step (and thus can
have any extension). alternatively magic2mime(1) or similar can be
used to be a little more robust than simple filename comparisons.

mime type - relevant program is done by /etc/mailcap (and ~/.mailcap)


simple wrapper scripts are provided for using this from the command
line:

 see - runs a program to view the file (like windows' "start")
 edit- edit a file with whatever program can handle it
 compose - compose a new file using an appropriate editor (or sound
   recorder, video grabber or something)
 print   - print the file

use these, these are good.



mime is good.

mime types are much better than simple extensions, since it also gives
a broad type (eg: text/*, image/*) - so programs can take guesses at
how to deal with unknown types.

mime types are much better than strict associations (like the mac),
since you may want to use a different program under different
circumstances. esp on unix, where you probably want an X program, a
console program, etc.

mime separates the "encoding" from the mime type. for example, if you
gzip the data, you still have the same mime type, only a new encoding
(this is why there is no application/x-gzip type). compressing on the
fly, etc, is thus a largely transparent act.

mime types are handled in user space, and so are easily customisable
by each user. nearly all mime programs allow each user to override
particular choices. try doing that on mac or windows.

/etc/mailcap is *much* more flexible than a simple windows
association. each mime type can have a description, a program to view
the type, a program to edit the type, a program to compose new files
of a type and a program to print the type. there are flags for whether
the viewer displays inline or needs to be run in a pager, etc. each
entry can have a condition to test to see if this entry should be used
(a typical test might be "test -n $DISPLAY"). there is no way you're
going to get that in the kernel, and no way i want to configure it on
a file-by-file basis.

did i mention that mime is good?



it irritates me that netscape seems to not read the standard
/etc/mailcap anymore - and forces you to set it all up by hand.
it used to "do the right thing" a few versions ago.

debian at least has an extremely well setup and maintained
/etc/mailcap. i hope other distributions do too.

There's nothing out of the ordinary in the log files. I got tcpdump

 Anything in the samba log files? Can you increase any log levels or
 debugging to see how far the printing is going? Can you do a tcpdump on

 Linux box onto the windows machine. If you can start eliminating where the

137, 139.. I was close :) I have both holly and hilly.. (from the first
time we see the female Holly her name was actually Hilly so Hilly was
talking to Holly. Holly is the main gateway which will explain the pop3

Ok the extended version is as follows if it's of any use. I'll try going
through it again, but I've done this once before when I first installed
Mandrake on here.. I did once get printing to a win98 machine to work
(it was on a redhat machine, not mandrake (although they are pretty much
the same)) but I lost the .conf file.

If no one has any idea for an easy solution I'll stop buggin ya all and
leave it alone until I've got real time to try and get it working in
December.

Thanks anyway,

Re: [SLUG] lpd not binding

[Erich Schulz]

You might actually have something wrong with the hardware interface or the
bios could be confused.

As root, ( and if your printer can handle ascii) send something directly
to the port, eg:
ls -la  /dev/lp0
and try it for all of the ports, and see if your printer responds
correctly.

If it does, you can eliminate the hardware as a problem, and look at the
networking.

try netstat -l and see if the lpd is listening on one of the unix sockets

Re: [SLUG] Associating filenames

[Jeff Waugh]

marty said something along the lines of:

 which begs the question, what did they do to bolt metadata onto the
 freebsd core for OSX ??


Umm... There was a really good article about this going around a while back.
Fairly interesting, it covered all the hacks they went through to combine
the two systems.

Bundles are an extension to the original fork/stream idea with Mac files,
allowing pretty much entire packages of software to operate as one "file".

Some of it was nifty, some just dirty hackery. Definitely linked from
Slashdot, so have a search on there. :)


Oh, and the Mac association system is a lot more flexible than people give
it credit for (and could be hacked over to support mime, etc).

[SLUG] Win4Lin problem

[Ken Caldwell]

The school where SHMBO teaches has decided to replace WordPerfect with
Office 2000 so I am trying to install it under Win4Lin.

The computer is running SuSE 6.4 with a Win4Lin kernel.  The hard drive
has just 4 primary partitions:-
/dev/hda1 is a DOS partition of about 30MB (not mounted under linux)
/dev/hda2 is a small linux partition /boot
/dev/hda3 is the linux swap partition
/dev/hda4 is the main linux partition /

there is a 3.5" floppy drive and the CDROM is a slave on the second ide
controller i.e. /dev/cdrom is a symlink to /dev/hdd.  There is currently
no hard drive connected as a slave to the first ide controller or as a
master on the second.

I have installed Windows95 (OSR2) under Win4Lin and now want to install
some of Office 2000 but the CDROM seems to be unavailable.  Windows
Explorer shows an A:\, B:\, C:\, J:\ and N:\ drive but if you click on
the CDROM (N:\) you get a dialog box which says "N:\ is not accessible
The device is not ready"  This is similar to the message you get if you
try to access the (non existant) B:\ drive.  The result is the same
whether the CDROM is mounted or unmounted under linux.

Does anyone have a suggestion on how to fix this?

TIA,

Ken

Check perms on your cdrom device

make sure the user running win4lin can read the cdrom device.

mouting it makes no difference in win4lin basically windoze is reading
from the almost raw device

Write the script anyway but as usual there's an easier way. If
you're talking about a permament connection and you want to make sure it
stays up, as long as you setup ppp correctly ie using a chat script. ie
to start your connection you can do something like
pppd call provider
then all you need todo is give ppp the persist option and it will dial

 make cron do something once an hour or once a day.
 I don't exactly understand what each column means in the 6 or so *'s that
 are at the start of the crontab entry. Anyone care to share the secret?


*   * *  * *some command   
minute hour  day_of_month  month   day_of_week
0-59   0-24 1-31   1-12 or Jan-Dec   0-7 or Sun-Sat

for day of the week 0 or 7 are Sunday

you can also do stuff like */2 which is every 2 minutes if it's in the
first field or

mon-wed,sun

for more info

man 5 crontab




 
 thanks,

The best way is to test for a PPPd lock file, I'd have thought.

RE: [SLUG] Script writing and understanding cron

[Dave Kempe]

   Write the script anyway but as usual there's an easier way. If
 you're talking about a permament connection and you want to make sure it
 stays up, as long as you setup ppp correctly ie using a chat script. ie
 to start your connection you can do something like
 pppd call provider
 then all you need todo is give ppp the persist option and it will dial
 back in autimatically.

I've had bad results with the persist option. It seems to try to reconnect
before the modem is properly released and ends up stuck in a permanent
looop.
Is there a way to make the persist option wait a bit until the last pppd is
finished?

THanks to all those who helped me with cron, I think i can understand it a
bit better now.

thanks

 test -f /var/lock/LCK..ttyS0 || ifup ppp0

ie: the lock file exists, or we run the command to bring the ppp0 link
up (you might need a different command, i just made that part up)

best is to get pppd itself to bring the link back up. check pppd(8)
for the "persist", "idle" and "holdoff" options. then you just
start/stop pppd when you want the link up/down.

 The other question i have is how to understand the entries in crontab.
 I have read a few cron tutuorials, and still don't exactly understand how to
 make cron do something once an hour or once a day.
 I don't exactly understand what each column means in the 6 or so *'s that
 are at the start of the crontab entry. Anyone care to share the secret?

see crontab(5):

  field  allowed values
  -  --
  minute 0-59
  hour   0-23
  day of month   1-31
  month  1-12 (or names, see below)
  day of week0-7 (0 or 7 is Sun, or use names)

so something like:

 43 13 5 * *  run_this_command

means: run "run_this_command" at 1:43pm on the 5th day of the month,
whatever month or day of the week that is.

once a day (at 6am):  0 6 * * *

once a week (3am tuesday): 0 3 * * 2


vixie cron (the one all linux distros use) is a lot more flexible than
the traditional unix syntax, and allows nice names for months and
days, ranges, lists and step values:

run each hour between 9-5, weekdays:  0 9-17 * * mon-fri

run every 30 minutes, for two hours in the morning, and two hours in
the afternoon:  0,30 9-11,16-18 * * *

run every 2 hours, weekdays: 0 9-17/2 * * mon-fri

run every 2 hours: 0 */2 * * *


that should be more than enough examples to get you going


(for daily or weekly system tasks, most distros have a directory, in which
all scripts get run. eg: on debian /etc/cron.daily/, /etc/cron.weekly/,
etc. so you just have to put your script in there)

Re: [SLUG] Script writing and understanding cron

As far as I know, persist can take an argument as to how long to
wait between retries. Whilst wardialling^Wtesting a free ISP at home I was reckoning 
on about four seconds being the absolute minimum you can get
away. any less than that and you get problems.

Re: [SLUG] Script writing and understanding cron

[Ben Donohue]

Hi Dave,
I use the following and it works a treat!

put this extra line in crontab to run a file every 5 minutes.
*/5 * * * * root run-parts /etc/cron.5minutes

then create a directory called /etc/cron.5miutes
put a file in there called ppp

in the file ppp have the following...
#!/bin/bash
cd /etc/ppp
ps ax|fgrep pppd|fgrep -v fgrep  /dev/null || /usr/sbin/pppd
exit 0

set the permissions on the file to execute.

then every 5 minutes the cron job will check if a ppp process is running. if so
then nothing will happen. if not then it will dial up.
a word of warning. if you dial the wrong number, you'll be paying for a call
every five minutes. check this whole thing manually first!

[SLUG] PPP under RH6.2 - Rec on HOWTO

[Terry Collins]

Can anyone recommend a relevant guide to setting up PPP under RH6.2?

This is a dial up on demand situation from the GUI (not me).

It has all changed since the last time I set one up and there is nil
relevant doco on the default RH install (I don't call steps to setup
kernel ppp as really useful, which is all I could find).

As near as I can work out, RH has changed to using WvDial for on demand
dialing - is this correct?

If wvdial is installed then yes it will use wvdial. Then you need to read
the man pages for wvdial.

If it aint then you can just use the ppp section of linuxconf. Add in a
connection with the correct details and go from there. Thats about as gui as
it gets. It seems to work ok tho.

Re: [SLUG] Associating filenames

[Peter Rundle]

Is there any ability in Linux to associate filename extensions, or
similar, with applications.  

One of the things with Unix is that, unlike dos with it's 8,3 rule
the "extension" is totally arbitary. Originally there was a 14 char
limit to file names and whether you had a dot in there was entirely
up to the user. Thus the idea of typing files by their extension
was historically pretty much a foreign concept to Unix. 

Currently there are at least three methods in use,

1. educated guess about file type based on content ("file" command)
2. explicit meta data in file (eg "#!/usr/bin/perl" )
3. .ext in the filename (Mime types)

All have their failings. 

Are there any other methods others know of?

with persist, pppd isn't supposed to exit when the connection

answer that one. (i just put "persist" in /etc/ppp/peers/provider)

also, there is something else running pppd in a loop - restarting it
immediately when it exits. this loop will be unnecessary when persist

[SLUG] Gnucash

[Jamie Honan]

In the past several people have mentioned using gnucash for book-keeping.

Is anyone doing this at present?

I'm particularly interested in the impact of GST, and generating
BAS.

[And please, don't let's stray OT. Just take the current situation
as a given, OK?]

Gnucash has no inbuilt handling of VAT, GST, BTW. Should it?
Could this be handled by the extension language?

Is it enough to split each transaction? I notice that MYOB First Accounts
(damn accountant made me buy it :) has a pretty gross GST handling
mechanism. It's 10%, no allowance for variations etc.

Hmm. I wish there was a user level help group in this area.

Thanks for your help Angus,
I found where to put the correct holdoff and other ppp options.
in /etc/ppp/options
I added persist and holdoff 30
works great!
Now it looks like this:

Oct 19 09:46:21 solid pppd[5434]: Hangup (SIGHUP)

[SLUG] DHCPD question

[Howard Lowndes]

With the dhcpd server there is the ability to pass several parameters to a
requesting client when it seeks to lease an address.

I have noticed that my dhcpd server is passing some parameter or other to
a Windows client that is telling the latter to resolve netbios using dns,
which is causing the client to try to resolve some pretty unreasonable
names.

Which of the dhcpd.conf settings is likely to be causing this, or better
still which setting would prevent it.

My dhcpd.conf is below.  The WINS server at .74 is working OK, but the
client keeps trying to resolve netbios names with .66 et al, which I don't
want.

When I look on the Windows client in winipcfg I see that the NETBIOS
Resolution uses DNS box is ticked, and that is not from any setting on the
Windows client, so somehow its coming from the dhcp parameters.  Could it
be that Windows is assuming that because it has been told about some dns
name servers then it is entitled to assume that it can use them for
netbios resolution.  Why would I not be surprised if that was the case

[SLUG] backup

[Alister Waller]

Hi,


Thanks for the comments on Routing Books.

I am newish to Linux and am finding this list a valuable resource for
obtaining help and information. Thanks Guys and Gals.

Next step for me is Backing Up. Can anyone suggest a good backup
script/program?
I wanted to do backups using cron on a customers site and have the backup
write a log of what it has backed up and to email me and the site IT person
as to the backup being successful or unsuccessful. Surely there are 101 of
these types of scripts out there.

looking forward to your replys.

Re: [SLUG] PPP under RH6.2 - Rec on HOWTO

  Can anyone recommend a relevant guide to setting up PPP under RH6.2?

...snip...

 If wvdial is installed then yes it will use wvdial. Then you need to read
 the man pages for wvdial.
 
 If it aint then you can just use the ppp section of linuxconf. Add in a
 connection with the correct details and go from there. Thats about as gui as
 it gets. It seems to work ok tho.

Thanks Dave

This is basically the reverse of how it went.
He had been fiddling with it and it didn't work consistently.

Look for stuff I'm used to in RH5.2 - not there
Try Linuxconf - easy as pie and works great to start - powered off modem
to stop it, then could find how the user, as opposed to root could kick
it off.

Tried the PPP dialer under gnome, which is just WvDial and it either
failed to connect or couldn't find modem. Found /etc/wvdial.conf, which
explained where all the crud in the setup was coming from, but ran out
of time, so we've booked another session to explore it.


tail /var/log/messages is great for anyone trying to workout what is
happening with ppp when setting up.
I also recommend ATF as the default modem init string. Record and
delete any other crud and only add it if you really need it.

If you are having trouble holding a modem connection, cutting the speed
back (AT command) is a good way to go. With all the rain about, older
copper installations will be feeling the pinch at the moment.

Re: aic7xxx.o (Re: [SLUG] One for the Kernel Guru's)

[Ken Yap]

You shouldn't have the driver for your root disk compiled as a module,
it needs to be in the kernel (or did I parse that wrong?)

Not so. That's exactly one motivation for initrds, to have a generic
kernel (e.g. distro kernel) that can boot on different SCSI disks
without having to compile all the adapter drivers in. The initrd
containing all the SCSI driver modules is loaded along with the kernel
by the bootloader, i.e. the BIOS, so the kernel doesn't need the Linux
driver for the root disk in the kernel.

What are you backing up to, another hard disk, a tape drive, CDs? Is the
data on the local machine, another machine on the same network or on a
remote machine via the net?

The email of what was done is easy, your backup tool depends on how much
money you want to pay and the sophistication you need. I use rsync to a
disk drive on another machine and then go to tape from there.

This is the easiest, and you can simply list the GST account

 I notice that MYOB First Accounts

In full accounts I can set GST as default or enter one of the Tax codes,

Because some of us don't always have access to a mail client that can read

from pine on linux. Hence I can't see HTML posts.

Also, HTML posts add extra size to messages which is not really required.

[SLUG] Set UID programs

[Jill Rowling]

What method do people prefer when wanting a program to run as a particular
user?
Examples:
At startup time, in init.d I might want to run a script as user
"blah"
Or I want to run a program as user "blah" where "blah" has less
privileges than my normal user account.

(Thinks of easily broken things like X and Netscape, hehe)

Some solutions:
su blah -c "/bin/sh myscript"
(This will prompt for password if I am not already root and "blah"
needs a password)
or
# chmod u+s blah myprogram
Then, when called, myprogram should run as user "blah", although it
probably won't work over NFS.

Which is preferable?
Are there other ways of doing it?

Jill.

It's a generally accepted convention that we don't send HTML formatted mail to
the list.  The same goes for winmail.dat - please turn it off.

 if so, why is that?

A waste of bandwidth for no gain in content.  Some of us will simply delete
HTML mail unread.

HTML formatting can more than double the size of a simple text message.  Send
that as multipart/alternative and you send both text and html versions,
tripling the size of your message.  Multiply that by the number of subscribers
and the number of messages posted to this list daily, and you have an enormous
amount of wasted bytes.

Personally I prefer to chmod the binary to run as the required user, although I
do not do this if the binary or script requires root access.
The reasoning is this. If th binary will only run as that user and there are no
other options in running it, then why put the password in every time unless it
is a security threat? User blah should not, of course, have the capacity to
wreak havoc on the scene.. thats a given, I'd hope!

Re: [SLUG] Html Email Format part 2

I hope you have asbestos pants on cos this is flame bait (8-)

I use Pine which is essentially text based, but it can handle html, it
just ignores the tags.

I think the main problem is bandwidth and the fact that html email can be
used to activate exploits in some browsers.

...and no, I don't download mp3, I do zap banner ads so that I can
download browser graphics because unfortunately eye candy seems to be de
rigeur these days and most sites are so badly designed as to be totally
meaningless without the graphics.

I am sure we all like to grab the odd mp3, but with that in mind, you'd be
refering to bandwidth we pay for off our own backs.

But as someone pointed out, when it comes to a mail list, not only do we
all pay for the emails, but someone also must pay for the server/servers
the email list is hosted on before it gets to us.

Personally, I don't want to be paying for HTML encoded emails when I don't
think it is necessary, unless of course someone wants to pay my bandwidth
costs.

It's commonly known as "lowest common denominator".

In other words, you distribute in the format that you're guaranteed your
LEAST capable interface can deal with.

This is a LINUX list. Believe it or not, Linux is still a text based
system - X11 is an add on, not part of the Linux core.

As for bandwidth - my mail is remote to my location - I telnet into a mail
server to read/reply to it - doing this with a GUI browser would be next
to impossible - sepecially over the 9600 BPS lines I'm forced to
occasionally use.

And yes - some of us DO you text based browsers - because it's simplier,
there's less risk of some form of bloody trojan being inserted in a visual
basic attachment, and it doesn't need the MASSIVE system overhead a GUI
based mail/news reader does.

My total bandwidth download in a month rarely exceeds 20 or 30 meg -
because I don't download pictures or MP3's or crap like HTML mail. The
only time it does is when I download something like a new kernel release,
or other large chunks of source code.

[SLUG] backup using rsync and file permission

[Ricky C]

hi All,

I have just started playing with rsync and in need of some guidance.

rsync (version 2.4.6) was installed on the "server", and version 2.4.1 on 
the "client"

On the server side, directories are shared using path such as below

#/etc/rsyncd.conf
read only = yes
list = yes
uid = root
gid = root

[folder_1]
comment = Old_Server (Remote)
path = /data/tools

[folder_2]
comment = Old_Server (Remote)
path = /data/Admin

On the Client side,

rsync -avz Old_Server::folder_1 /backup/folder_1

Everything seems to work fine, all permission bits are kept, however the UID 
and GID comes up as numbers. Does the 2 machines require the the same 
/etc/passwd file, and its shadow ??

What is the best way to manage this ??
Also, is there any way to rsync the whole file system ?? so I don't have to 
set 20 different paths in the rsyncd.conf.

Thanks in advance
Ricky

I'd say it's more than just a few lines. Your posts with the winmail.dat
attachments are twice the size of everyone elses (your "backup" post was
6k, other recent posts are 2/3k). Imaging if every slug post doubled in
size -- it adds up. Now imagine that you're the guy paying for SLUG's
email bandwidth.

As someone already mentioned, some mailers send messages with both text
and html versions together, wasting even more bandwidth.

Computers are capable of quite alot these days, but I fail to see the
need to put "a few extra lines of text" in an email, just to make your
message come out in 10pt Arial instead of the default text mode font. I
mean, most people who send in html don't even use any of html's
features! They gain nothing from using html, except bulk. Then there are
those who think they're 'l33t because they have a textured backround,
fancy font and coloured text on their emails. Their 2k message weighs in
at 37k! Now who's wasting bandwidth?

As for pictures and mp3's - they are relatively bandwidth friendly. Just
compare the size of jpg's and mp3's to the size of their heavyweight
cousins bmp and wav! Yes they are far larger than your average html
mail, but many people have made it their business to make them less so.

Less hardware requirements. You don't need a gui, you don't need X,
which again leaves you with a faster, more reliable machine. Netscape
crashes frequently, X/? occassionally locks up, but linux has never
locked/crashed.


 Is this a linux geeky type thing??

No, definitely not.

 Seems strange when you look at what computers are capable of that a minority
 (I am taking a stab in the virtual darkness) still insist on using a text
 based mail reader. You mention bandwith, I am sure a lot of you download
 pictures and Mpeg 3's etc which hog a lot more of that than a few extra
 lines of text in an email.

The MAJORITY of people are still on dial up lines with 33.6K modem and
so they suffer badly from that little bit of extra data. That extra data
actually COSTS people money as quite a few people are on timed access,
both ISP and STD calls.

We try to follow consensus here, not the democratic principle which is
dictation by the majority. 

Essentially, there is no perceived benefit to everyone from allowing
html. I'd much rather have rejection of html posts before closing the
list to subscribers only.

Re: [SLUG] Gnucash

[Kevin Waterson]

h to split each transaction? I notice that MYOB First Accounts
 (damn accountant made me buy it :) has a pretty gross GST handling
 mechanism. It's 10%, no allowance for variations etc.
 
 Hmm. I wish there was a user level help group in this area.

I had a look at gnucash and others at the beginning of the finiancial
year and whilst it is coming of age, it is not yet ready for real
world use.

Our solution was to write a php/MySQL BAS preparation utility that
plugins into our php/MySQL Point-Of-Sale, total time to do BAS
is now about 5 mins.

Of course this system has many shortcomings but meets our needs.

Thank you.

 Can I ask why people use non-html enabled mail clients?? What is the benefit

Because mutt is the best mail client I've found so far.  Because I appreciate
content far more than style.  Because almost all HTML formatted mail adds
absolutely *nothing* to the content of the message.  A different font, the odd
bold or italic word or phrase, but what else?  Nothing.  Because HTML can be
used to spread malicious content.  Because HTML mail is bandwidth-unfriendly.
Because I just don't like it.

This list is (mostly :-)) about helping people, surely if you're asking for
help you do it in the way most appreciated by those whose help you're seeking? 
Irritating people by the manner in which you ask for help is not going to make
them more likely to provide that help, is it?

 based mail reader. You mention bandwith, I am sure a lot of you download
 pictures and Mpeg 3's etc which hog a lot more of that than a few extra

Stop thinking of yourself and think of those that host the mailing list.  Isn't
it just good manners to minimise the cost to them?  IIRC (from a message on
this list ages ago), before the list moved to the new servers, the traffic was
enough to saturate a 128K ISDN link, and they don't come cheap.  I have no idea
how much bandwidth it uses now, but it's likely to be more rather than less.

Re: [SLUG] Html Email Format part 2

Alister Waller said something along the lines of:

 I have now switched to plain text.


Hooray! :)


 Can I ask why people use non-html enabled mail clients?? What is the benefit
 of this? Is this a linux geeky type thing??


Matt Elkins, the original author of mutt (the email client I use) quotes
himself on the mutt.org homepage:

 "All mail clients suck. This one just sucks less."

Mutt happens to suck a lot less than most text-based mail clients, and
supports - nay, *handles* the multipart annoyances that are the default on
most GUI mailers (especially the ones from our friends, Microsoft, who come
up with brilliant new ways to obfuscate what really amounts to *plain text*
with every revision of their various mail clients).

When I receive HTML email, mutt invokes w3m to render it. When I receive
that tdif junk, mutt fixes it up to show me the plain text part only.


 Seems strange when you look at what computers are capable of that a minority
 (I am taking a stab in the virtual darkness) still insist on using a text
 based mail reader.


Not so sure about a minority. I think you'll find the fetchmail / procmail /
mutt trio on a lot of our desktops. I'd recommend looking at the User-Agent
and X-Mailer headers, but that's a couple of clicks away in your client. :D

If you use a GUI mailer exclusively, you don't get the benefit of ssh'ing
into your machine to read your email as if you were at your desktop... and
don't be telling me you'd do it over X! ;)


 You mention bandwith, I am sure a lot of you download
 pictures and Mpeg 3's etc which hog a lot more of that than a few extra
 lines of text in an email.


When it comes to you or I, sure, that bandwidth isn't a problem. However,
there are 464-- 465 people on the mailing list...

Taking a random tnef email on the list, the text/plain version was 0.5k,
however the tnef junk was an additional 2.4k, so the email is about six
times the size of what it needed to be. Take that 2.4k and multiply it by
465, and you have just under a megabyte, never mind the overhead.


Then there's the Pine users, but we won't go into that. :D

[SLUG] HTML Email format part 3

[Alister Waller]

Ok, all very good reasons for using text based email. I wasn't being
aggressive, unlike some replies, I was asking the questions out of genuine
curiosity.

Now, in regard to bandwith. Why do some people send the same email to me as
they send to the list, i read the list??? surely that is creating bandwith??

[SLUG] Html Email Format part 3

[Rodos]

jest
Well for those of you who complained about my email it was actually in
ASCII text format with a non-proportional font.

Can I ask why people use html enabled mail clients?? What is the benefit
of this? Is this a Windows thing?? Seems strange when you look at what
computers are capable of that a minority (I am taking a stab in the
virtual darkness) insist on using new fancy and extended mail reader. You
mention bandwidth, I am sure a lot of you download all sorts of crap, so
how do you spare any bandwidth for those extra lines of text in an email.
/jest

Alister, you probably think we are an unfriendly bunch, its just that you
walked into a vegetarian food court asking the customers sitting at the
tables would they like to try out the new tasty pork bits from Company 
X. You just know you are not going to get a favorable reaction.

An example, take the following text. Most of the Linux geeks here can
simply pipe this text into a postscript viewer and read the message
contained within. You can read some of it (go to the last 10 lines or so),
but its basically annoying and adds nothing to the message. Thats why we
don't send postscript or HTML.

Look forward to helping out with your Linux questions Alister, but its
nice to see the sluggers draw there sword, tis been a while.

Rodos

[SLUG] Damn sendmail.mc and m4

[George Vieira]

Hi y'all,

I had this problem before and can't find the information on how I fixed it
but I need to turn off this DNS lookups with sendmail. (I think someone else
had this problem before).

I added into the MC file

FEATURE(`accept_unresolvable_domains')dnl
FEATURE(`accept_unqualified_senders')dnl

as suggested and tried to recreated the .CF file using

m4 /etc/sendmail.mc  /etc/sendmail.cf

but gives an error 

/etc/sendmail.mc:11: m4: Cannot open /usr/lib/sendmail-cf/m4/cf.m4: No such

I remember I was missing the M4 stuff and needed to rpm install it but can't
find the file name on the RedHat CD.
I have a /mnt/cdrom/RedHat/RPMS/m4-1.4-12.i386.rpm but it says it's

RE: [SLUG] html email format

[Jill Rowling]

Of course anyone atempting to read Rick's howler using Outlook Express would
not have seen the point he was making!
Therefore an excellent in-joke.
At least Outlook (without the Express) gives the user the option to send
stuff as plain text for those of use forced to use it (mumble mutter) at
work.

RE: [SLUG] RE: Damn sendmail.mc and m4

[George Vieira]

Now that I founnd the files needed I still get problems. I'm trying to get
rid of DNS lookups in sendmail and use a relay host.

I'm not sure exactly what's needed in the sendmail.mc file but I get these
errors now.

[EMAIL PROTECTED] citadelcomputer.com.au: Name server
timeout
[EMAIL PROTECTED] Transient parse error -- message queued
for future delivery

Sendmail site says to add
FEATURE(`accept_unresolvable_domains')dnl
FEATURE(`accept_unqualified_senders')dnl

which I tried and create a new CF file and restarted etc..etc.. but to no
avail.

Is there something I've missed? 

thanks,

I've had lotsa fun with

begin  xx

by emailing the above, accompanied by a limerick, that the hapless
Lookout user cannot see. Without fail, the poor user was most
astonished when I explained what was happening, and felt somehow
cheated.

Thanks to whomever posted the "begin  " gotcha.

I tried to do the same thing and failed - I ended up setting up DNS on
our firewall and having the the system use that to do the lookups.  

Is it possible to set up a fake named that returns the relay hosts IP
address for every lookup?  Or would that break other applications?

Re: [SLUG] RTF viewer for Linux?

 All,
 are there any RTF (Rich Text Format) viewers for Linux?
 I get so many of them that I dont wanna ftp all the time from an NT box
 to download it from a linux box.

Well there is strings. Or you an rtf-fm (read the friendly - fresh
meat) which lists two tools based on a search of the word "rtf".

#18: rtf2htm  - An RTF to HTML converter which supports tables.
#19: rtfeeder - Converts rtf files to html files.

You could run it through these and pipe into w3m or lynx. A lot of the
word processing tools for Linux support RTF. I know WP does and SO
probably does too.

[SLUG] Promiscuous mode

[Howard Lowndes]

I have just noticed this in a log:

Oct 19 13:11:41 stratos kernel: eth0: Transmit timeout, status 0d  media 08.
Oct 19 13:11:41 stratos kernel: eth0: Tx queue start entry 11797532 dirty entry 
11797528.
Oct 19 13:11:41 stratos kernel: eth0: Promiscuous mode enabled.

I don't know what caused lines 1  2, but line 3 worries me cos the
interface certainly is in promiscuous mode and I cannot seem to get it out
of that mode.

Should I be worried?

No problem with that.

You will break any other app that uses the DNS.

define(`SMARTHOST', esmtp:smarthost.domain)dnl
This should be all you need as sendmail passes it on to the smarthost for
delivery.  (Remember it still needs to look up smarthost.domain in the
DNS).

Re: [SLUG] RTF viewer for Linux?

[Jamie Honan]

Ted is an RTF viewer and editor.

However which rtf? The format changes regularly. Ted often throws
up lots of warning messages.

StarOffice is quite nice, but in a completely different league
for memory requirements.

If you only want to see the text (which is often all you need)
I notice I have rtf2text, which seems to want a perl module
RTF::TEXT.
