Is there a constraint requiring that this be done with a single regex?
Depending on the context, there might be a number of more suitable
programmatic approaches.

For example, an unfinished, untested, inefficient, slapped together
bash/grep approach might look like this, without getting tangled in
regex syntax...

password='a1#'
hitcount=0
if $( echo "$password" | grep -q "[A-Za-z]" ); then echo "Got alpha";
let "hitcount = $hitcount + 1"; fi
# Repeat for numeric and special chars
# Check $hitcount == 2 or $hitcount >= 2, depending on your requirements

What's wrong with brute force?

bool password_characters_good_choice(char *s) {
  int matches;

  matches = (match("abcdefghijklmnopqrstuvwxyz", s) +
 match("ABCDEFGHIJKLMNOPQRSTUVWXYZ", s) > 0);
  matches += (match("0123456789", s) > 0);
  matches += (match("%$#@", s) > 0);
  return (matches > 2);
}

where match(s1, s2) returns the number of occurances of
the characters of s1 in s2. That's pretty easy to implement
and is a prewritten function in a lot of languages.

Cheers, Glen

Actually on second thought you may want to drop the first ?. It also 
depends on whether the characters specified in the above 3 conditions 
are the only allowable characters or not.

A crude but effective method is to delete one only instance of each 
regex and then compare the string lengths. For example,

#!/bin/bash

EXPRESSION0="ABCDefgh1234%$#@"
EXPRESSION1=`echo "$EXPRESSION0" | sed '
s/[A-Za-z]//
s/[0-9]//
s/[EMAIL PROTECTED]//'`

echo "${#EXPRESSION0}"
echo "${#EXPRESSION1}"

A tool called txt2regex can help you build these - it keeps asking you
questions, and show the regex corresponding to your answers. Also
produces regexes for the languages you specify.

Since I don't have a better answer, I should probably keep quiet, but 
there is a flaw in your regex:
[EMAIL PROTECTED]:~$ perl
my $var = 'a';
if ($var =~ /[EMAIL PROTECTED]|[A-Za-z0-9]+|[EMAIL PROTECTED]/) {
print "True\n";
}
^D
True

$var doesn't match the required 2 out of 3 characters, but still matches.

Thats not that great a specification :-). Can you give some examples of

If there is only one image in the tiff file, perhaps converting

The message from adobe reader is "drawing error". Some documents convert
OK, but some don't. Other programs simply hang when opening - eg,
document viewer and pdf viewer.

Can anyone suggest another command line method of conversion? The files
I'm dealing with right now are tif output from hylafax. 

I've seen Open Office suggested, but I would prefer something I can use

Gonzalo, thanks

I'm going to have oldmail server forward all mail to new mailserver with
smtp static assignement, then, re-run
rsync old:/var/mail/vhost with new:/var/mail/vhost
with 'delete' option

perhaps rerun rsync with delete over the weekend few more times

-alter MX;
-redirect smtp old > new
-alter pop CNAME
-rsync

I think that should, do,

OOPS, forgot:

I've done a few mail server migrations in the past and a bit of DNS trickery
helps in not loosing mail. What I would do is set the TTL really low (< 10
mins) for the domain I was transferring (so that all records change their
TTL for that domain) 2 or 3 days before the actual migration. On migration
day, I would forward ports 25,110,143 (SMTPS, POPS and IMAPS (if you use
them) to the new mail server to ensure any new mail is forwarded straight
onto the new mail server. You would need to actually resend packets with the
source address changed to be the old mail server so that packets are routed
back through the old mail server (otherwise it wouldn't work ... A (client)
-> B (old mail server) -> C (new mail server) -> A (client) .. it needs to
be A (client) -> B (old mail server) -> C (new mail server) -> B (old mail
server) -> A (client) ), which means any emails will generate traffic for
both, your old & new mail server but since it's only for a period of 48
hours, for me it was never an issue.
I would then copy all mail over (using whichever method you prefer .. as
suggested by Jeff & David). At this point it's probably a good idea to
update the MX record (or the A record, if you want to keep the MX record it
points to) so that it points at the new mail server.
After 24-48 hours, I would turn off the port forward and monitor the logs to
ensure no legitimate email is being received.

Hope this helps. Good luck!

Sorry, I meant to say that you'd have to change the TTL for all domains
hosted on the mail server. I confused myself (and possibly others) between
migrating one domain and an entire mail server for a second.

James, Dave, thanks

between the time I copy it, and, the mail server is transferred, there are
bound to be emails deleted/removed from main server, (as well as new ones
added),

so, do I re-run it to get just new mails since;
then rerun it with '--delete' to get rid of collected mails, is the the
idea ?
or can I run a single pass to both get-new and delete-if-notexist ?

also, I enabled 'ssh' for root, started rsync, then disabled root's ssh,
is there another way of allowing temporary access without editing conf
files/restarting daemon?

There are plenty of proper ways to do it!

Given that you're not actually synchronising or updating anything, you could
use tar and netcat. That's way fast.

> what the proper way to add/remove shell, can I just edit /etc/passwd ?

If you mean adding a user, you should use the user management tools provided
by your distribution (such as adduser/useradd).

Check the -a parameter for rsync. :-)

why no just rsync it as root with -av and you preserve all the ownership 
and don't need to worry. OTOH, if you stuff it up, a recursive chown 
will fix it, so no need to worry.

What's so important about that information besides the fact that its
just a rehash of the information on Novell's own site?

[SLUG] migrating mail server Maildirs, howto copy ?

[Voytek Eymont]

I'm migrating mail server to new server;

all mail is for  virtual users in /var/home/vhosts/%dom.tld%/%user&/Maildir;
owned by '5000' as so
drwx--5 5000 5000

I was looking at activate the new mail server, and, then, rsync the
existing Maildirs to 'synchronize' old & new servers;

as I'm the only user with shell access, should I just add shell access to
user '5000' for the purpose of running rsync, then, remove it?

or, what's a proper way to do this copy ?

what the proper way to add/remove shell, can I just edit /etc/passwd ?
do I need to give user '5000' a name, or can I just use '5000' in rsync ?
