Should work on any *nix based distro with X11/fontconfig installed 
... which is about as close to a "standard" as I've come across in 
*nix land! (and yes, Mac is *nix for this purpose).

That's not a bad little piece of code then.

I've got a user reporting that my app under puppylinux is reporting 
the wrong time when compared vs NIST time.

Perhaps the easiest thing to do is to redefine NOW based on a NIST 
offset.

Woohoo!  Just came across a way to make Ctrl-V work in the bash shell.
You need 'xclip' installed. To install, I did

	$ sudo apt-get install xclip

then I pasted Josh Triplett's nice short code at 
http://bash-hackers.org/wiki/doku.php/snipplets/xclip

into the bash shell, and then Ctrl-V started working!

Maybe you could write a simple proxy for system/ports/input, catch 
CTRL-V then redirect clipboard:// content to console?

Wait a minute, I can call xclip to get the right clipboard contents...
	>> call "xclip -o"

Doc, or anyone, do you know how to write a proxy for system/ports/input 
?

I would try to wrap a custom port wiring all methods to the console 
port then I would replace system/ports/input with that new one and 
see if the "proxy" port works. If it works, then you can intercept 
the incoming events and add your own handlers. But that's only theory, 
as much other low-level parts of REBOL, it's not documented, so I'm 
not sure it would work.

Hmm.. sounds a bit too complicated for now - might have to wait for 
another day...

but, how do you think I would replace system/ports/input ? By just 
:

	system/ports/input: my-port
?

Ok, I'll give it a quick go to see how feasible it is. My first try 
about an hour and half ago, just using the console port looks like 
this:

I've tried replacing system/ports/input/awake with an awake function 
similar to above, and it doesn't seem ever to be called. If it's 
possible at all I think making a handler object with all the functions 
(open close write etc.) *might* work.

I tried making a handler object with stub functions.

Is this a key logger?

I had a go at it again with Gabriele's way of doing it. So far I 
can only intercept input and output when enter is pressed, not at 
individual key presses. I think I can only open system/ports/input 
in lines mode, the same as the default. From memory, now, I seem 
to remember somebody having a go at this and arriving at the same 
point. (Can anybody verify that?)

(still, ctrl-c and ctrl-v have always had a different meaning on 
terminals, so I'm not sure replacing them is a good idea. in particular, 
most likely you'd need to trap ctrl-c by trapping SIGINT... and that 
does not look like a great idea to me...)

Gabriele, could elaborate on that idea a bit? I'm having trouble 
visualizing how it would work.

in my example, you have your own port using your own scheme, and 
its sub-port which is the original system/ports/input. this sub-port 
need not be the original, you can open console:// yourself with your 
own flags (eg. binary). then you can process one char at a time, 
figure out line ending yourself, and send the entire line to the 
other side.

Or is there a way to set the handler in a console port?

Anyway, so it seems like you suggest to replace the default port 
at system/ports/input with an equivalent one which the system is 
expecting (ie. a direct/read/lines port), and then the subport can 
be a custom console port with binary, one char at a time stuff.

(It's unclear to me the relationship between a port and its subport. 
I know the port manages the opening/closing of its subport, but how 
can the port in lines mode transfer individual chars from its buffer 
into the subport ? Or do they both receive from the same input simultaneously 
automatically?)

basically, on read you call read-io on the subport, maybe modify 
the buffer, etc. on write (for the output port), you can do the same, 
modify the buffer, then use write-io on the subport. wait on the 
subport is called by the system whenever wait on your port is called 
(that's why there's a get-sub-port function there).

well, going to login to the console and have a poke around

Sorry to hear you've been attacked, Graham.

I hope it is not too much work to get it all back together....Don't 
work all night!

Looks like it was not personal -- just some automated tools seeking 
vulnerabilities.

You seem to be on a fairly recent version of Apache, but that does 
mean you may be some months behind on the security patches:
http://httpd.apache.org/security/vulnerabilities_22.html

Server id  says 2.2.3. (that may be just a reply string, not the 
real situation of course).

I have an idle Cheyenne running on a Linode server without a domain 
name. it's been there for a couple of months now. I was a bit surprised 
to already see bots looking for wordpress, admin pages and attempts 
to submit various scripts for injection in the access log. Well, 
I guess I shouldn't be surprised.

At least I might have a clue how they did this.

wonder if it is a permission issue on the index.php file

I'm ready to bet it was a deki wiki or php vulnerability rather than 
an apache one...

now to figure how to backup the mysql files and transfer them to 
a backup of the vm

Looks like I was not the only vm user who was attacked.  Mindtouch 
are investigating.  They suspect a PHP5 vulnerability that I guess 
I should have updated :(

the vulnerability has been identified.  There is a vulnerability 
in the rich text editor which allow a user to upload a php file as 
an image type and then browse to it executing it.  http://xinha.webfactional.com/ticket/1363
 So, not really a php exploit ...

I wrote a software with DRAW with 2 arrow and 2 text (Cartesian axes), 
in windows works, in Linux appear just the vertical row and notihng 
else...

News to me. Is there a similar trick under OS X?

That's a pretty old post

I tried to change the agg script to point to a ttf font file under 
OS X. It doesn't display.

Simply put - starting "saslauthd -a shadow" daemon, then uncommenting 
2-3 lines in sendmail.mc, restarting sendmail, and voila, it was 
done ...

Thinking about providing my brother with some webmail option on my 
Linux server. In the past, I used simple Squirrel mail. Then I know 
some ppl do use Horde. Now my friend suggested me a Zimbra. Isn't 
Zimbra a little bit too much for just an occassional web option to 
pop3 account?

I thought so - more a groupware than a simple webmail interface to 
email, right? Most of us use Thunderbird anyway, so ...

setup file is like this: 
#!/bin/bash
#
# iptables example configuration script 
#
# Let's not lock ourselves out of the server
#
 iptables -P INPUT ACCEPT
#
# Flush all current rules from iptables
#
 iptables -F
#
# Allow SSH connections on tcp port 22

# This is essential when working on remote servers via SSH to prevent 
locking yourself out of the system
#
 iptables -A INPUT -p tcp --dport 22 -j ACCEPT
#
# Allow HTTP connections on tcp port 80
#
 iptables -A INPUT -p tcp --dport 80 -j ACCEPT
 iptables -A INPUT -p tcp --dport 443 -j ACCEPT
#
# Set default policies for INPUT, FORWARD and OUTPUT chains
#
 iptables -P INPUT DROP
 iptables -P FORWARD DROP
 iptables -P OUTPUT ACCEPT
#
# Set access for localhost
#
 iptables -A INPUT -i lo -j ACCEPT
#
# Accept packets belonging to established and related connections
#
 iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
#
# Save settings
#
 /sbin/service iptables save
#
# List rules
#
 iptables -L -v

I tried from console too .. if firewall is all on ACCEPT it works 
.. if not this happens : 


>> send [janko-:-itm-:-gmail-:-com] "asasd asd a"                        
               Net-log: ["Opening" "tcp" "for" "esmtp"]
connecting to: secure.emailsrvr.com
** Access Error: Cannot connect to secure.emailsrvr.com
** Where: open-proto
** Near: smtp-port: open [scheme: 'esmtp]
either only

does a direct tcp connection on port 25 work?

Try adding :  iptables -A OUTPUT -i lo -j ACCEPT

On second thought, that wouldn't help. Try adding a few -j LOG rules 
to help debug.

It took me half of day of looking but I think I am close to it now.. 
when I run the script I get 

iptables: No chain/target/match by that name

and it's realted to this line:

 iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT


after much digging it currently it looks that the vps is missing 
"state" kernel module which is given there by -m "meaning match" 
.. I just wrote the vps host computer admin and I hope he will be 
able to enable it

Petr, I'm not sure why someone would want a non-standard, hard to 
use shell over Linux, but, ok... :P

Gabriele - you should know what you are talking about, no? I use 
MT for 3 years, and the docs are there, there is a forum, there is 
a wiki. It allows so much complicated stuff like traffic bonding, 
easy scheduling/shaping, mangling, scripting, virtual interfaces, 
dynamic lists, etc.  that it is not even funny to compare it to bare-bones 
Linux ....

so, what the hell has that to do with Janko's problem (a firewall 
for his server)?

the issue is not whether it's free or not. the issue is that they 
are REMOVING features for no reason at all. Why not just add their 
own windows UI (that of course it's only for windows! they could 
not do like anyone else and make a web interface that works everywhere...) 
on top of a custom linux distribution that ALSO gives you the ability 
to do whatever you want with it IF you know how?

My router is a debian lenny box. I'm so much happier now that the 
mikrotik router in the antenna is just acting as a bridge and I don't 
even know it's there. less crap to learn and worry about...

go read Carl's blog again about people not having a clue about the 
business they run. go read Chuck Moore's interview that says the 
same thing (complexity means that we are doomed). I can't undertand 
why only so few people on this planet get it - how can everyone else 
think that more complex is better...

It has NOTHING to do with MT and your claims are simply false. If 
you are so brave, then go, and replace your bad MT with another Debian 
Box. I wonder, if it would make you more happy. MT is not bug-free, 
I never claimed anything like that. My MT suggestion was relatad 
exactly to the SIMPLICITY factor. You call it complex? Man - it is 
like you never used REBOL, right? MT brings simplicity to the wifi 
providing, that some other solutions are not even funny to suggest.


MT Linux abstraction is like a VID dialect upon Linux - yes, it can't 
do everything. But I can't come-up with anything it does not do for 
me for 99% of my usage cases. Yes, I noticed your OpenVPN problem, 
not supporting UDP, and yes, it sucks, but it does not mean that 
MT does not serve its purpose.

Also, PLEASE, I beg you, do *read* what I write. I never said my 
problems are due to mikotik. I said my problems are due to my ISP 
not knowing what they are doing. You said that mikrotik allows "normal" 
people to set up a WISP. Right, they do, and the result is that they 
waste MY time *because* they know nothing about this job. This was 
*your* claim, and it seems to be consistent with what I am seeing.

The criticism I made to RouterOS was very targeted and very simple, 
and you of course completely ignored it. I said two things: 1) there 
is absolutely no reason they had to add the stupid shell they have 
when you connect via SSH 2) there is no reason why what they do could 
not have been implemented on top of debian, or any other distribution, 
thus allowing people who know what they are doing to provide extra 
services that are beyond what's in their default configuration. That 
is just a stupid choice. So, most people don't care or need, and 
for them MT may be a good choice. That does not make them a good 
alternative to a linux box, neither a good alternative to Janko's 
problem above, and from what you say they may be even making things 
worse.

oh, my third criticism to MT, 3) there is no reason why they are 
offering a windows-only gui instead of a web-based one like everyone 
else in the world.

Gabriele - let's make a peace in the above case. I am sorry if I 
offended you :-)

hi, do you have a solution for the BROWSE problem on linux ?

a work around is to use CALL like this "call [firefox "http://www.rebol.com"]

Claude, I have a similar solution, I redefine browse in user.r
browse: funct [ url ] [ call reform [ "x-www-browser" url ]]
So you can do
browse http;//www.rebol.com

But docs, and bugs don´t work ( you can redefine them too If you 
want ), but I think you don't like this solution.

Hi, any idea how to get the Word Browser from Rebol -> Tools to work 
on Linux? I get an error after I click a category and then a word:
** User Error: Bad face in screen pane!
** Near: show main
This is using Rebol/View 2.7.6.4.2 on Arch Linux.

sounds like a font problem

Thanks for trying to help :) With font problem, do you mean something 
like a missing font? I got these installed: ttf-ms-fonts, ttf-dejavu, 
ttf-bitstream-vera, xorg-fonts-100dpi, xorg-fonts-75dpi, and xorg-fonts-misc. 
Any idea what kind of font would be missing for the Word Browser?

Probably not a font issue then. Works fine here on OSX so sounds 
like a Linux specific error. Does RebGUI work? (REBOL/Demos group)

Yeah works on OS X for me too, got that on my laptop. RebGUI seems 
to work fine, went through a few of the tabs, nothing crashed.

Let's see if anyone else on Linux has the same issue, otherwise a 
feedback is in order. Good find.

Budzinski: No problem here with word-browser when I select a category 
and then a word. Works fine on Kubuntu 9.04 and Rebol/View 2.7.6.4.2.

Try to reload again the script with right button and then reload 
over the Word Browser Icon

Normally it's a problem right at startup of View and it's fixed by 
installing the X11 fixed size bitmap fonts, but you seem to have 
those already. Are there any other bitmap fonts packages that you 
can install?

You could try xorg-fonts-alias, in case a font is installed but not 
found because the name doesn't match

I don't see much else you could try. Maybe the ttf-ms-fonts, because 
it has popular font names, but that would be a new case of the problem

No change. I tried to install a few more font packages but those 
didn't help either. But thanks for your help, it was worth a try 
:)

Budzinski: usually it's the bitmap fonts, but you had those installed 
already, so maybe it's not a font problem. "Bad face in screen pane" 
could also be the script trying to open a window with negative or 
zero size, or things like that. Maybe a negative offset could cause 
that error as well.

Gabriele, wouldn't an error in the script mean that the Word Browser 
shouldn't work at all? It does work fine on Windows and Mac OS X 
and from what ManuM said, it works on Kubuntu Linux too. But thanks 
for your input on this :) Maybe REBOL is incompatible with a newer 
version of a package. Arch Linux is a rolling release distro (daily 
updates compared to Ubuntu where you get updates every 6 months in 
form of a new distribution release). If it's that, then this problem 
will pop up for other Linux users in a few months too, when their 
distributions update to use newer packages.

I'll try to ask in the Arch Linux forum about this tomorrow. There 
probably won't be anyone using REBOL there but maybe a few people 
are willing to try this out. I'm far from being a Linux guru, if 
someone with more experience would try the Word Browser on his Arch 
Linux system, the possibility of a configuration error on my part 
could be ruled out.

You could have a look in the script to see what it's doing at that 
point

Yeah I started looking at the code. It's a bit hard to debug for 
me though. The error doesn't give any line number, it just says "near 
show main". I searched for "show main" and found three occurances 
in the source. I'm completely new to REBOL so going through everything 
in the code would take me quite some time without being able to narrow 
it down first because everything looks alien to me and I have to 
look it up to see if something in the script looks wrong. Is there 
some good tutorial available on debugging REBOL code? Or is there 
some trick to find out the last line that was executed? I do have 
access to the terminal at that point, the view is frozen but the 
terminal still accepts commands.

I'm not aware of a specific debugging tutorial. It takes experience, 
yes. It's not ideal, either, and in REBOL 3 the debugging abilities 
are greatly improved

Budzinski: my guess is that for some reason, either a size-text fails, 
or some othe code fails, leading to a 0x0 or negative pair somewhere, 
or something else weird. REBOL's codebase is just too old, so it's 
always a bit at odds with Linux. :)

Yeah on Mac OS X there are a few problems too. The bottom of a scrollbar 
isn't shown for example (I guess the resize graphic in the lower 
right corner covers it). And the console is unusable when the view 
freezes. Whatever I type ends up as garbage and gets mixed up with 
the command history so the only option at that point is to restart 
REBOL. REBOL seems to work only good on Windows at this point. But 
cross platform is always a hard thing to achieve, I haven't found 
any solution other than Java & Swing that "just works". Well, maybe 
Adobe AiR but only on Windows and Mac OS X, on Linux you get into 
trouble as soon as you use something other than Ubuntu :)

More a problem with VID (the dialect) than REBOL/View per se. I think 
REBOL lives up to the "write once, run everywhere" moniker better 
than Java ("write once, test everywhere") ... *as long as* you don't 
rely on OS-specific calls/fonts/paths, etc.

We will for Windows and OSX ... but the problem for *nix land is 
the continuing lack of a standard distro to target for. You can't 
make *any* assumptions about what you're running on. I think the 
RT approach of, "this is the Linux distro we are targeting, uses 
others at your own risk" is about the only practical option.

I never had any trouble with Java + Swing working everywhere, but 
I only recently started using Java for real (about a year ago I think) 
so maybe it's just gotten a lot better now and was awful in the past 
^^ But I guess it also depends a lot on what you are trying to do. 
Programming shouldn't be generalized. There are so many vastly different 
categories of programming (database, web, server, games, system, 
scripting, image/video processing, automation, A.I., embedded, etc.) 
that your mileage may vary depending on your area of interest. And 
don't get me wrong, I don't want to bash REBOL in any way. Apart 
from being completely new to the language which means that I can't 
really say if it's bad or good yet, I wouldn't be here if I didn't 
think it was useful and had potential :) Thankfully I already had 
some basic experience with Scheme, Clojure (a lisp) and Haskell so 
that REBOL's syntax didn't come as a shock for me :)

We are waiting for R3, but R3 takes kind of long to complete. We 
learned a lot with VID2 and VID3/View3 should address our problems 
of the past. We don't try to pretend, that REBOL is ideal solution 
for you ....

From my experience, no language is ideal for a person, but for a 
specific task instead. I try to use the best tool for the job when 
I can (same goes for operating systems, I use Windows, Mac OS X and 
Linux). At the moment all my projects are C++, Java, Clojure, Ruby, 
Objective-C, C#, Python and Vala (compiles to C). And sometimes I 
use even two or three languages in combination. I can't say if that's 
the best solution but for me it works good so far ^^

I guess a demonstration of its stretch is rebcode, which I had no 
idea was possible. It won't be in R3, but the fact that it's even 
possible to do in a scripting language and was implemented in as 
short time as it was is a great demonstration of how generic REBOL 
is.

Gabriele, that Java is open source should help a bit too ^^ But from 
what I read maybe not as much as it could. Seems like Sun needs to 
be forced to accept patches and it can take months until they give 
in. May have been just a few rare cases though, people who are angry 
about something are often more vocal than people who are satisfied.

Henrik, I read about rebcode. Any idea why it's not going to be in 
R3? Sounded like a pretty cool feature. Although I would probably 
never use it, haven't done anything with assembler yet and I don't 
think I ever will (which usually means that something will happen 
that will force me to learn it tomorrow).

I've read the explanation multiple times, but BrianH knows it better 
than me. It has something to do with how functions are implemented 
in R3, which would make rebcode work slower in R3. Therefore it's 
better to spend time perfecting extensions, so you can write time 
critical code in C and use that instead. Rebcode is not for beginners 
anyway (but it did bring up that oldschool feeling for a while :-)).

It'll be at least a lot easier to write C extension instead of using 
an assembly like language ^^ I've used inline C and C++ in the past 
when writing Ruby code. I don't know much about C/C++ because I always 
try not to use them, but I read that nowadays the gcc compiler has 
gotten that good that sometimes the code it produces is as fast as 
hand written assembler would be.

perhaps i must do a link with libstdc++6

look in the debugging group, this was just discussed about a few 
hours ago!  next to last post tells you where to get the libstdc++5 
package....

thanks a lot

thx for the info kaj and gabriele. looks like a non journaling FS 
(ext2) and a noatime mounting will speed things up. will post some 
experiences after a while using this new stuff.

If I use GCC to build the extecutable there is a bunch of libs implicitly 
included. Doesn't seem to be if LD is used.

Is that on C++ code? It makes a difference whether you use gcc or 
g++ to compile

Ubuntu 9.10 is quite good. I've only had to visit the terminal a 
couple of times to get SMB filesharing working since I first booted 
it 5 minutes ago and only one cryptic error message appeared.

Even if it has more, to have a workable installation you need an 
extremely lean distro

Here's a very good one:

Here's a Linux with older apps especially for old machines:

At the danger of sounding repetitive, Syllable is one of the few 
systems you could reasonably try on such a low-memory machine - especially 
for an Amiga enthusiast

i think I will give Ubunto a try. IIRC it's debian based.
