AFAIK, on 64bits Linux, 32bits librairies are located in /lib32 and 
not in /lib. This may be the reason why you can't run REBOL.

Doc: I have /lib/ and /lib64/  -- do you think that lib are 32b libs? 
or do I have to install them ... the client told me now he thinks 
admin installed the 32b libs at his vps

client said that reinstalling linux would be a little problem, so 
this will do for now ... 


I installed the ia32-libs ( apt-get install ia32-libs ) and now rebol 
works

I think 32 libs are in lib32 now (which I got after installing that 
package) and cheyenne is probably looking in /lib/ like the rebol 
code in exception shows ..

I fix that issue in my developement version of Cheyenne a week ago. 
Just edit %misc/unix.r and change the access path to libc like this 
: 
	any [
		exists? libc: %libc.so.6
		exists? libc: %/lib32/libc.so.6
		exists? libc: %/lib/libc.so.6
		exists? libc: %/lib/libc.so.5
	]

I just wanted to say that I isntalled cheyenne from source now and 
wanted to fix that code in unix.r .. and ran it via rebol cheyenne.r 
and it already worked without fixing any code :)

Browse on Linux temporary solution
browse: funct [ url ] [ call reform [ "x-www-browser" url ]]

And browse works, and all commnads based on browse ( docs, bug, changes 
) too

I have an ext3 filesystem and I need to add "nls=utf8" to /etc/fstab 
for this filesystem to correctly convert filenames that are coming 
from window machines.

very nice and simple. thanks.

Robert: I work with kubuntu 8.10 but I think that can help

This is one line from my "/etc/fstab" file. It mounts a fat filesystem 
at /media/DESARROLLO ( dir /media/DESARROLLO already exists )
/dev/sda7 /media/DESARROLLO vfat rw,utf8,umask=000 0 0

With umask=000 the access to /media/DESARROLLO will be rwxrwxrwx 
( the owner is root and the group is root, I don't know how to change 
it )

I'm going to try to convert 1 single filename and see what happens.

most programs do not check that the file name is valid utf-8. normally, 
you're using a utf-8 terminal so there is no way you can type an 
invalid filename. but you can easily create one using rebol for eg. 
or using escape sequences in the shell and so on

ahhh yes using the -h flag does make it explit and clear

I never really liked linux... (being a fan of "real" unixes which 
actually do work all the time  ;-)  and now I am remembering why.

I got a bare-bones debian install, and am trying to add X11 to it. 
can any one point me to a real link with explicit instructions?

I've tried following instructions from a few sites which show a 3 
command line install, but that fails, since it doesn't install x11 
, only xwindows, and then it reports its missing about 2% of the 
files from the distribution server itself.

hum.... I seem to remember doing but I was falling asleep on my keyboard 
by that time... ok so I should de an apt-get update first, and then 
attempt the xserver-xorg  ?

there are a few missing files, but so far it at least was able to 
get to the point where it actually installed the X 11 apps and utilities... 
not just a few libs

oh, that's nice. do graphics and fonts work?

no clue  !!  I havn't even started putting content yet :-) 


working on new ssh-admin upload/download/shortcut features  and  
then  remark_mod.


until remark_mod is working, no content will be visible. forcing 
myself to implement what I've been wanting to do for years  ;-)

this is an exciting time for me...


 I've been inching my way to this point for almost a decade.  building 
 libs and tools one by one with a precise vision in mind.   I am now 
 at the point where I can start integrating all of that into "products", 
 and so far there is very little things to change, all the lego bricks 
 fit together  :-D

yes/no...More interested in remark_mod and remark v2

I am sourcing a file with alias commands in them, but they aren't 
actually being applied.

typing those exact commands directly in the shell works.


I know alias is not a file command, but a bash internal operation, 
but how can I get bash to source the files and apply the aliases 
to my login automatically?


the echo within the file IS printing on the shell, so its not just 
chmod thing... any linux gurus can help me?

I remember that things like aliases are a bit more flexible (dangerous 
too) in csh and tcsh

what's strange to me is that the echo within my sourced file was 
sent to the console, clearly indicating it was being call as a script, 
unless there are different bash script evaluation levels and I don't 
know how to set it up.

me again with linux problems :(


I made binding to Haru PDF library ... it works on windows but now 
I am trying to make it work on lunux from where it will be serverd 
via cheyenne... the problem is that I have 64bit linux and so this 
libhpdf.so compiles as 64bit shared library

I looked on net and saw gcc can compile as 32bit with -m32 option 
if you have something called multibit "gcc -print-multi-lib" .. which 
I seem to have .. I changed ./configure to add this flag but then 
I get some c compilation errors ( I could sucsessfully compile it 
without this option) ...

Any ideas how to do this? I am trying to compile it now on my other 
VPS which is 32bit and copy file to the 64bit vps but I have no idea 
if this will work

and my messages get "eaten".. aha here it works

I said over there "yipeee!!! .so compiled on 32bit debian and copied 
to 64bit one works!!

Any idea how to start a rebol script via ssh (I have a VPS) .. and 
detach it from my console so when I close it it won't stop running?


cheyene executable file does this automagically (I have no idea how) 
.. if I run cheyenne through .r script it exits with me .. but my 
problem now is not with cheyenne but I have a custom script that 
should run in the background. After googling yesterday I found out 
about >> nohup script-to-run & which seemed to still work if I closed 
ssh and started another one but now I see for the second time that 
after a while it exited as it isn't running any more ...

but I am not sure it's intended for what I described above .. basically 
running apps in background -- so they run (for days and weeks) after 
I close the ssh

You can use screen to detach a session and reconnect with it later, 
possibly from an entirely different machine

Kaj , thanks .. it seems screen is very beneficial tool for working 
on ssh , I will start learning and using it

I am using drach now and works very nice ... but screen is awesome 
tool to and I will use it in general sshing now (thanks Graham! I 
added dtrace sample to that wiki)

the command "nohup"  may still exist and be usefull

yes, nohup is very usefull too , with &  .. for example nohup some-longer-tast 
&  .. but for my concrete example I wasn't able to figure out why 
rebol script terminated after a while, not on every exit but at some 
point I just saw it wasn't running any more .. and by the look of 
nohup.out file there was no error .. but "rebol terminated"

Janko, basically the thing is, if you want to see the program's output, 
you need to use screen. This allows you to have output and detach 
it. Otherwise, you can just redirect the output to a file (or to 
/dev/null), then you can exit your ssh session without problems.

i'm not sure if it's installed by default anymore, but there also 
used to be a "nohup" program which would redirect your program's 
io and detach it (run it in the background).

Graham: .. and it can also help others like in this case .. as I 
said above I have the wiki for exactly this thing linux commands 
because I use them just enough so I keep forgetting the more tricky 
ones http://www.manage-websites.com/doku.php?id=tutorial-linux-shell
<-- here they are

Gabriele: I was using nohup like this >> nohup /.../rebol script.r 
&  << but at 2 times rebol script got terminated for some reason 
after a while.. it did stay alive after I closed and reopened ssh 
but when I came later it wasn't running any more and by looking at 
output file nohup.out last thing was "rebol terminated" so it didn't 
 exit on error but got terminated in the same way if I press Ctrl+C 
(maybe I just need to read more about nohup)

now it works with dtach and it works ok so far

What distro works best with sdk-2706042.tar.gz "out of the box" (with 
regards to rebview and fonts)? I just need something I can quickly 
install under VirtualBox and do some basic cross-platform REBOL GUI 
development/testing ... without having to hack it to make it work.

OK, so I've downloaded Ubuntu 9.04 (64bit) and got it running under 
VirtualBox, then I download and untar/zip the REBOL SDK and open 
a console session. cd to the REBOL dir and do a chmod +x and type 
./rebview ... which comes back with a "file or dir not found message" 
... anything else I need to do to get REBOL working? Oh, and what 
font looked best with RebGUI in your opinion?

I am using Ultimate Extreme-a custom Ubuntu-under VmPlayer and installed 
View. It works fine. Then I emailed my license and put it in the 
root of .rebol but when I start View it does not see the license 
? Ideas ? Thanks !

OK, I've got it running under a clean install of Ubuntu 32bit. Now, 
how do I determine what scaleable fonts REBOL can actually use? (%/usr/share/fonts/truetype/freefont/ 
doesn't seem to have all that many ... and they look pretty ordinary 
atsize: 72).

(and all I want is the clean install of Ubuntu to use a good looking 
font)

OK, got it working on Ubuntu (and Mac) with:

fonts: copy []

foreach [font-name style] parse/all (call/output "fc-list" s: copy 
"" s) ":^/" [
	all [
		not find fonts font-name

  (size-text make face [text: "A" font: make face/font [name: font-name 
  size: 10]]) <>

  size-text make face [text: "A" font: make face/font [name: font-name 
  size: 12 style: 'bold]]
		insert tail fonts font-name
	]
]
sort fonts

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).

Anyone know of any issues getting the time and date under Wine?

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!

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.

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 did replace system/ports/input and output and it works, i used 
that to "broadcast" what is typed at the console to other listener 
(eg. for online demos or lessons or things like that).

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?)

system/ports/input needs to be in /lines mode IIRC... but you could 
open console:// in /binary mode, process it, and behave in lines 
mode for your custom scheme. More complicated than my example above 
for sure...

(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...)

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.

Hmm... more thinking and lots of questions come up.

Would your above system need WAIT ?

The only way I got console port to work is to set its awake function 
and use WAIT.

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?)

when you're not in pass-thru mode, the only functions that get called 
are read and write. they both work at the binary level (read-io and 
write-io), so the conversion to lines is done by the native code 
under the hood. i don't know if you need pass-thru, though, and whether 
pass-thru will work for system/ports/input.

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

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.

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

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...

how I define Font and Fontpath, and how I can make that work in Windows 
and Linux?

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

does anyone have any idea why is this happening to me.. I setup iptables 
firewall and now my rebol send method (to SMTP on some completely 
other server) doesn't work any more..

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
#

Thanks for help Graham and Doc .. I wanted to reply multiple times 
but altme didn't want to accept my text and it was disconnecting 
me

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

you should be able to load the module yourself with modprobe etc. 
(and it's strange iptables doesn't load it automatically, i thought 
it did)

modprobe gives me the following error: 

FATAL: Could not load /lib/modules/2.6.24-2-pve/modules.dep: No such 
file or directory


I looked and it seems that VPS container can't access kernel modules 
.. I am still waiting for administrator because there was some linux 
conf two days now.. he should fix it today ... 


I will check out shorewall .. I need quite simple confihuration , 
no forwarding, just close everything and lock ssh to some static 
IP-s

ShoreWall, MonoWall ... and the winner is - Mikrotik :-)

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 ....

Simply put - our example - small to middle network, 600+ wi-fi users, 
50+ MT nodes, which even lamers like me and my brother can properly 
build. Would we be possible to make it using bare-bonesLinux? Absolutly 
not. Your reaction is imo typical example of why Linux fails in the 
long run. PPl want easy solution, not guru stuff.

can you explain me why mikrotik supports openvpn but *only* on tcp 
and not udp? that makes no sense at all.

It might have nothing to do with Janko's problem. But - I saw you 
suggesting him ShoreWall, and in that regard I did mention Mikrotik, 
because I have experience with it, and simply put - nearly all WISP 
are using it, and that means something. Some ppl do replace Cisco's 
with it. The system is no-brainer - just insert CF with MT, boot, 
and there you go. If some node dies, you can replace it in 10 minutes, 
no virtualisation or advanced technique used, just its clever design. 
Besides that - MT is still Linux underneath ...

As for OpenVPN - I don't know - it is kind of "recent" addition, 
as community screamed for it. There is l2tp, pptp, ppoe and I use 
simple pptp ....

I can give anyone demo access to my central router, to look around. 
My opinion simply is, that some things don't need to be entirely 
free, in order to be considered. And something like 30-40 USD is 
cool price ...

I lost the messages i was typing to you yesterday, and you know why? 
My internet connection does not work. Guess what is my ISP? One of 
those WISP that uses mikrotik for everything. Yes, I guess that means 
something. It means that incompetent people just damage other people's 
work.

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...

Gabriele - after reading your messages, I have to say one thing - 
I always have great respect for your and for your knowledge, especially 
in regards to REBOL. But your last remarks are so completly off, 
that I really wish you don't mean it for real.

There is so much to the wi-fi layer to know about in praxe, that 
it is not even funny. There can be plenty of reasons, why your connection 
is crappy. First of them might be RT's provider itself. That can 
be checked easy enough - if your connection is not broken only for 
Altme, then most probably it is not RT's provider, but your connection. 


From there, I would check your provider. Wi-fi is NOT cable, it never 
will be, and the technology never claimed to be 100% problem-free. 
99% of problems are NOT related to MT and its SW, believe me. The 
clear sight to your provider antenna, the weather, the antenna quality, 
pigtail quality, pigtail/calbe isolation (if water is there, the 
signal might drop SIGNIFICANTLY), general wi-fi signal pollution 
in wifi crowded area, etc. etc.

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.

The complexity vs simplicity factor can be very easily checked. My 
brother, who would not be absolutly able to set-up linux router, 
has set-up 50 MT based router nodes. We are serving 600+ ppl, with 
problems here or there. We have 3rd iteration of our network, having 
our MT backbone rock-solid. Some P2P connections are going to be 
replaced with 10GHz ones, becaue we know where's 5GHz limit, and 
we try to use the right tools for particular needs.


But once again - I visited at least 5, maybe more courses, related 
to radios, frequencies, their correct usage, cables, antennas, with 
profi (lended from T-mobile) equipment, where we checked on the antennas 
and cables parameters, and I can tell you, that with wrong Antenna, 
pigtail, cable, with wrong installation, you can ruin your connection 
quality even down to 40%. No SW, being it MT, or Debian, or StarOS, 
can fix it.

So in the end - use what you are happy with. But don't try to put 
down publicly system, you have no deeper experience with, please, 
as apparently all WISP providers are happy with it (and not only 
them, some ppl go so far to replace Ciscos), and it might serve well 
to some other ppl, looking for simple yet sufficient solution for 
their usage case. By reading your comments, noone would probably 
ever considered Mikrotik, and that is all it is about - let's not 
create myths, where there are apparently no myths involved, and the 
system might work satisfactory to many ppl  ...

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.

that said, their hardware looks nice and cheap.

I am not offended, I'm just sad that everytime I say something simple 
it gets interpreted as something big and complex that would hurt 
people...
