AltME groups: search

I've setup the DNS entries for the domain according to blogger's 
tutorial.

I am moving all my web site and web apps to a new server. Unfortunately, 
I have to change all the DNS entries too, so interruptions might 
occur during the next 24-48h on the following sites:

- cheyenne-server.org
- curecode.org
- static.red-lang.org
- softinnov.org

I will provide the basic ones for Red: TCP, UDP, DNS, HTTP(S), SSL, 
SSH/SFTP, SMTP. Also, I would like to have a few more for remote 
or local storage builtin: Dropbox, MySQL, Postgresql. 


You are welcome to contribute other ones to that list (IMAP, SMTP, 
MongoDB, CouchDB would be nice additions).

me neither -- I'm seeing the Portal does not exist page; and a slightly 
odd message that it may take time for DNS changes to propagate.

That must be it, then: DNS for the apparently new subdomain rebol.informe.com 
still propagating

Okay.....I can see it now; so maybe it was a DNS thing.

I wonder, if Altme a) uses at least TWO machines to connect to for 
lookup purposes like DNS does b) can remember IP address so next 
time look-up server is not available, it can try direct IP connection 
.... if not, it is imo plain stupid as at least b) imo would not 
take more than few hours for programmer to add .... now Peter will 
come once again, and call it - "unreliable" :-)

technology is surprising sometimes...   my DNS provider just sent 
me a mail to confirm my phone number.... 
- I click on the link in the mail, 

- a web page opens up with a form to verify my number (it was wrong!)
- I click a little link that says... call now!

- not 1 second after hitting the link, *my phone actually rings* 
and it spells out a magic number

- the next web page that arrives after "call now!", has a field to 
enter the number!
- press submit.
- done!

the most advanced captcha I've seen so far.


this mixing of web and physical space is always a bit strange... 
is it not?

I have also unified portal, where I can see all my domains (actually 
something as 7 or 8), I can change MX, DNS entries, FTP, hostings, 
etc. etc.

This time it was not Safeworld, but Rebol.net or DNS problem.

async dns does not work but everything else was working fine.

even for the client: well, since the detective worked, i assume altme 
could too; altme does not require draw wich could be a problem to 
compile on solaris, and as long as it does not require async dns 
i think there should be no problems.

it may have been a DNS problem, because I was connected to the r3 
world the whole time and could send messages just fine. of course 
it's no fun if there is no one to respond. :-)

So what do I think AltME id doing wrong, or at least not making life 
to admins easy? There is no problem for me to to open ports on FW. 
This is not about opening ports only, but precisely speaking it is 
about setting DST-NAT to your target PC on internal network:


1) AltME records your internal IP adress when setting up your world. 
Don't even try to run it on different PC in your internal network. 
Even if you have all ports OK, this one thing will ruin all your 
efforts. Dunno if it adds to any kind of security, but in my eyes 
it is completly unnecessary obstacle. But maybe it is usefull when 
running altme servers fully on your local network, so that AltME 
"DNS" can direct your local clients to correct internal altme server. 
I can live easily with this one, but ...


2) Today I created new world. No matter how you try, it always registers 
AltME world on port 5400. There is no ability to set it differently.


3) Even if you start altme -s "my-world" -p 5401, it will not help 
you, and it still opens the world on port 5400 (at least that is 
what I saw with netstat -an), which is imo a bug


4) even if you change \servers\my-world\info, still no luck. When 
you go to http://www.altme.com/cgi-bin/lookup.cgiand you type-in 
your world name, you still can see, that AltME.com has registered 
5400 port, but not e.g. 5401


5) even if you run your altme -s "my-world" -p 5401, and even if 
you send your client to 5401 port by changing \worlds\my-world\config.txt, 
you still has no lack. It is apparent, that no matter how your client 
is instructed, it takes info from altme.com for granted, and overrides 
your local settings, which can be proven by 6)


6) Running two worlds - my-world on 5400 and my-world1 on 5401 (names 
obfuscated here), I found out, that Altme client does not care of 
Altme server name at all. That can be proven by typing my-world1 
and using account from my-world, you are succesfully logged in to 
my-world, instead of my-world1, as client obtains port 5400 instead 
of 5401


I have one and only one question - how can I change my world port 
number on altme.com, or in other worlds - how do I REGISTER world 
on different than 5400 port? :-)

one of BCE's MAIN DNS went down today for almost 30 minutes...

I think we are waiting for Carl to update the DNS records for AltME.

However, if someone else wants to take over this Server, I think 
we are open to that.

dear all, does anyone have an idea about  "Boot Error 951" mentioned 
above? Is it a rebol initialization problem? Maybe betwen rebol process 
and its dns resolving brother process?
..or is it more related to uniserve code? thx

has anybody used core async dns ? I am trying to resolve domains 
using a port per domain but I get a sequential behaviour. Ideally, 
this should be done with a single port, sending requests and getting 
replies in an async fashion. snippet below

	port
	/local res
][
	res: 	copy port
	print 	[port/user-data/host res]
	remove	find system/ports/wait-list port
	false
]

"xxafda" "www.ebay.com" "www.amazon.com" ]

		 p: 	open/no-wait make port! [
				scheme: 	'dns
				host:		"/async"
				user-data:	reduce ['host h]
				awake:		:f-awake
			]
		insert	tail system/ports/wait-list p

gabriele, thanks, does your async library handle async dns ?

ok, maybe I mix things incorrectly. I will ask other way - async 
and non-blocking are two separate things, right? I don't need async 
console etc., that I might solve via threading. But - will it be 
possible to have fully non-blocking behavior? Even for DNS reads 
(it is now) and opening connection?

what you describe above, can be easily obtained by doing the dns 
resolution in one task. what you see is a port, that to you looks 
exactly like an async dns port. except that it is implemented in 
mezz code rather than being native.

Gabriele - we have async dns already, don't we? dns:/// .... but 
what is currently blocking without ability to set timeout is trying 
to establish a connection (SYN) ... or can we make it also a non-blocking?

pekr,  async DNS is not really "async" , it is non-blocking

there is a great lack of information from RT !  The problem is core 
is still widely propietary and it is imposible to find out how things 
like async DNS work without RT publishing the info. I was interested 
in writing an async DNS using Gabriele's async as a reference but 
I now find that udp has bugs ! Another surprise to discourage me 
!

on OS X and Linux, for every instance of rebol , 2 processes are 
launched, the second for dns, right? is there any known bug? I have 
an difficult to debug situation , when quitting cheyenne after some 
load, some handler process goes 100% cpu, but the dns process is 
no more there, this make me think it may be a problem with rebol, 
otherwise also if one process would go 100% CPU, the dns one would 
still be present, help!! 8)

not even sure the problem is with call, what is sure is cpu goes 
full, the dns help process quit ok, ktrace on that process return 
nothing

about my problem (a couple of messages above) I can confirm that 
the problem doesn't exist with 2.7.5.

2.7.6, supposedly fixed [call] but did it introduce a new bug? has 
it maybe to do with hevy cpu, timing, rebol dns helper process?

when you say hosting account, you mean a server on the net with its 
own dns/ip which is different than the ip being served to you by 
your access provider... yes?

This should work, where server is the ip adress or dns name of  the 
relevant machie

opened: []

for i 1 65536 1 [
   all [
		print i
		attempt [p: open join tcp://server: i ]
		attempt [close p]
		append opened i
    ]
]

I've juste noticed the nice values we get for event key when pressing 
function keys !!!

in order: console listen tcp udp icmp dns local odbc oracle

I am just learning everything I can, so knowing about Block Parsing 
sounds good to. tuples! are quite good for IP addresses, but ip addresses 
often need exactly 4 parts. I wonder why there are no datatypes specific 
for networking? e.g. networks & masks & inverse masks and domain 
names. and DNS records.

So an entry in the log file starts like this: "[15/May/2010 17:59:56] 
IP address 190.101.1.10 found in DNS blacklist SpamHaus SBL-XBL..."

>> spam: "[15/May/2010 17:59:56] IP address 190.101.1.10 found in 
DNS blacklist SpamHaus SBL-XBL..."

== {[15/May/2010 17:59:56] IP address 190.101.1.10 found in DNS blacklist 
SpamHaus SBL-XBL...}
>> replace/all spam "]" "" replace/all spam "[" ""

== {15/May/2010 17:59:56 IP address 190.101.1.10 found in DNS blacklist 
SpamHaus SBL-XBL...}
>> blk: parse/all spam " "

== ["15/May/2010" "17:59:56" "IP" "address" "190.101.1.10" "found" 
"in" "DNS" "blacklist" "SpamHaus" "SBL-XBL..."]
>> date: blk/1
== "15/May/2010"
>> time: blk/2
== "17:59:56"
>> ip: blk/5
== "190.101.1.10"

another thing I experienced: The server was moved to a new location. 
For some reason, everything went FUBAR, because DNS had not been 
set up. This caused connecting to the server to take about 60 seconds 
to get through. When I looked in the list of connections, it just 
says "logging in" for that long time. I connect to the server with 
an IP address, not a host name, so what's going on?

The server may try a reverse dns request on your IP when you connect 
and ends with a timeout after 60secs.

Using Vid, I get for F1 onwards, console, listen, tcp, udp, icmp, 
dns, odbc, oracle, msql, crypt, compress ...

BTW: The hanging happens even for connection to "localhost". But 
those connections are resolved via the machine name and a DNS lookup. 
The DNS server is operated by an external provider.

Check your DNS config and test your accesses with telnet.

dns

it's the dns helper process.

one is for DNS lookups.

The question has been asked a few times recently. I had not noticed 
this before until Carl talked about how R3 doesn't need an extra 
process for DNS.

You also need to make a DNS lookup to get MX records for destination 
mail servers.

I was thinking more of a simple mail server that only accepts mail 
for one's own domain.  In that case, I wouldn't need to do any mail 
forwarding. But I guess I still need to do a DNS lookup to confirm 
that the server sending mail is who they claim to be.

Anyone know how to view a website you are are self hosting. I know 
you can view it using localhost but I want to use the url. I remember 
reading somewhere that it was possible but I can not find it now. 
Something about the DNS...

amacleod - isn't there /etc/hosts file? Maybe you could put it there? 
Generally, I use DNS based technique, pointing particular name to 
the particular IP. Even more interesting situation is, when you want 
to redirect public server IP to the internal IP on local network 
:-)

whois still says catalog.com is the registrar.

The issue is the DNS record....

I noticed this morning it rejected a legitimate email from my own 
hotmail account as the address given by the EHLO gave a none reverse 
DNS ... but checking it again, it was okay.  So, some type of dns 
timeout error I guess

Need some help...Can't seem to get Uniserv working on my XP laptop. 
 This is my first try...so I don't have enough experience to see 
what is happening.  Do I have the wrong version of core?

>> uniserve/boot
[uniserve] Async Protocol Admin loaded
[uniserve] Async Protocol DNS loaded
[uniserve] Async Protocol FastCGI loaded
[uniserve] Async Protocol HTTP loaded

** Script Error: change expected series argument of type: series 
port
** Where: install-plugin
** Near: change pos/2 new
>>

see related post wrt async dns in the core group. Is the behavior 
mentioned in the core group possible with Uniserve async dns support 
 ?

I figured out how to stop the service tying up the 80 port , When 
i run this is what I get: >> do %/c/temp/rebol/uniserve/uni-engine.r
== true
>> uniserve/boot
[uniserve] Async Protocol Admin loaded
[uniserve] Async Protocol DNS loaded
[uniserve] Async Protocol FastCGI loaded
[uniserve] Async Protocol HTTP loaded

** Script Error: change expected series argument of type: series 
port
** Where: install-plugin
** Near: change pos/2 new

I have these settings in ruter conf:
HOST IP
ROUTING
VIRTUAL SERVER
CUSTOM VIRTUAL SERVER
SPECIAL APPLICATION
DYNAMIC DNS
MULTI DMZ
UPNP
NAT
ADVANCED FEATURE

But for the casual user, all that is unimportant. Only the style 
designer needs to know this.

The casual user simply types:

	view [
		group 2 [
			label "IP Address" ip-field
			label "Gateway" ip-field
			label "DNS" ip-field
		]
	]

Google Public DNS: http://code.google.com/speed/public-dns/

Also: "Note, however, that because nameservers geolocate according 
to the resolver's IP address rather than the user's, Google Public 
DNS has the same limitations as other open DNS services: that is, 
the server to which a user is referred might be farther away than 
one to which a local DNS provider would have referred. This could 
cause a slower browsing experience for certain sites."

Is it me, or the example to read a dns address is broken ???

Needed to do reverse dns lookups

yes http://rebol.wik.is/Rebol3/Schemes/Dns

locally define your DNS names in your hosts file (/etc/hosts or C:\WINDOWS\system32\drivers\etc\hosts) 
to be able to simulate locally virtual-hosts.

maybe there is some kind of dns error. I tried in IE right now, it 
seems to load some page, which is empty - nothing appears on screen. 
So I pressed right mouse button/properties, and there is following 
item: 

res://ieframe.dll/dnserror.htm#http://localhost/test.php

Pekr, you have an issue with your localhost DNS resolution. You should 
check that your hosts file is not messed up. If you can fix the localhost 
problem, here's a workaround, in Cheyenne archive, edit the mods/mod-fastcgi.r 
file, find the fastcgi://localhost:9999 expression and replace it 
by : fastcgi://127.0.0.1:9999, that should work.

One thing I was considering.. rather than paying for expensive servers, 
like amazon EC2,  to host low usage sites, you could run mulitple 
copies of Cheyenne that would sync up.. and maybe an S3 bucket for 
data.. one at home, one at work etc. .. couple these with dynamicDNS 
so in the event one went down, the other(s) could detect that, and 
update the DNS to take over.  Could do some DNS based load balancing 
if necessary.  If you want to get real crazy.. you could share backup 
servers amongst agreeable Cheyenne users...probably wouldn't host 
e-commerce that way, but wikis / publicly available data would be 
fine.

A Cheyenne users dynamic DNS server would be handy.

yess this is how I have set it up before too... in a test I did with 
apache in front... the appache in revers dns also allows two distribute 
load on several machines, so it also allows to easily scale once 
you've got load.

I have no problems with subdomains, but maybe it has to do with the 
dynamic DNS

The DNS needs to be configured to resolve subdomains to your IP number

it redirects dns searches to nowhere  :-)

Best way to redirect domain.com to www.domain.com: correctly setup 
the DNS records.
Best way to do it in Cheyenne: (untested)

domain.com [
	root-dir %/...
	redirect 301 "/*" "http://www.domain.com"
]

www.domain.com [
	root-dir ...
]

For my web sites, I always achieve domain aliasing using CNAME DNS 
records.

Yes, some SMTP servers apply such restrictive rules, but not the 
big ones (AFAICT). But the more important is to have a reverse dns 
that matches your servers domain.

from the 'win-get-dns function

it tries to obtain the DNS servers using 2 strategies depending on 
the REBOL kernel used. If GET-REG is available, it tries to get the 
info from the registry, else, it calls "ipconfig" and parses output.

Can you copy/paste the 'win-get-dns function to a fresh console to 
see what happens?

In source mode, you can hardcode the dns server : win-get-dns: 1.2.3.4

ooops ...

Did encapping solved your DNS lock up issue on Win7?

win-get-dns: does [ return 208.67.222.222 ]

So, you have to hardcod the DNS server IP address?

let me try my own dns

Are you using DNS server from your ISP or OpenDNS?

The DNS server you're using are either under heavy load or just not 
very reliable (happens sometime). Anyway, my MTA should at least 
retry 5-10 times before giving up and reporting an error. I'll add 
that feature tomorrow.

can we fall back to opendns if the dns server fails?

try hardcoding opendns ip as last value of 'win-get-dns, you'll see 
if it's more stable than your local DNS servers.

SVN r23 :


FEAT: improved logging and error handling for dig/SMTP/MTA modules.

FEAT: integration of deferred retries in MTA for temp errors recovering 
and greylisting passing.
