" Mobinil 3G USB modem H4(|{ " , With (Debian - lenny) linux ; How to configure the prepayed Mobinil Sim in their ZTE MF626 USB 3G modem

I first installed the modeswitch debian (sarge)_ package ... which didn't work with debian lenny. The following steps shows how to correctly set it up:

# Insert the modem.
# Wait until the modem automounts in your Desktop.
# Eject the modem and wait a few seconds until it's available to connect and switched to modem mode(as it's first recognized as a SCSI device).

Open a Terminal and type:

eject /media/ZTEMODEM

Wait 15-20 seconds so the modem can switch from Storage to Modem mode.

--

ls /dev/ttyUSB*

If it is recognized, proceed.


---Now it's time to sniff the used configuration.----

#Using a (USB-sinffer) while modem is connecting to my provider we got the required data in log file.

#Then i had to unhex | grep the contents (unhex.c is a small c code to convert hex to string):

grep '^[0-9a-f]\+:' log.txt |sed -e 's/.*://'|unhex |tr '\r' '\n'|grep -av '^$'

#Below the output

ABORT BUSY
ABORT VOICE
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT "NO DIAL TONE"
"" AT
OK ATV1
OK ATE0
OK AT&F&D2&C1S0=0
OK ATS7=60S30=0
OK ATS0=0
OK ATDT*99#
CONNECT ""

#Then i created a file in /etc/chatscripts/ called mobinil (or whatever you like), this how i tell pppd (point to point protocol daemon) to dial the ISP's modem and go through any logon sequence required.

#Now Create a new file /etc/ppp/peers/provider containing:

/dev/ttyUSB2 115200
debug
noipdefault
usepeerdns
defaultroute
hide-password
lcp-echo-interval 20
lcp-echo-failure 3
connect '/usr/sbin/chat -v -f /etc/chatscripts/mobinil'
noauth
noaccomp
default-asyncmap
maxfail 3
holdoff 10

This is a file that contains characteristics of the remote peer peer-name. Typical characteristics include the remote peer's phone number and chat script for negotiating the link with the peer.

#That's it, now from a terminal type: pon

I hope this may some how helped you and welcome if you have any further questions.

The ZTE-MF626 from mobinil is locked, here's attached some AT commands which check lock type:

check net-/SIMlock

Tin Hat: High security Portable Linux

Tin Hat is a Linux distribution derived from hardened Gentoo which aims to provide a very secure, stable and fast Desktop environment that lives purely in RAM.

Tin Hat boots from CD, or optionally a pen drive, but it is not a LiveCD. It does not mount any file system from CD via unionfs or otherwise. Rather, Tin Hat is a massive image (approx. 2.3GB) which loads into tmpfs upon booting.

One pays the prices of long boot times (5 minutes off CD, 2 minutes off pen drives), but the advantage afterwords is that there are no delays going back to the CD when starting applications.

Tin Hat aims towards the ideal of guaranteeing zero information loss should the attacker physically acquire the box - either the adversary is faced with no file system to even begin cracking, or if any non-ephemeral memory is found, the adversary should not be able to tell if he is looking at encrypted data or random noise. Of course, achieving this ideal is impossible, or at least highly improbable, but it is nonetheless something one can strive towards. Tin Hat is a baby step in that direction.

Ruby on Rails?

Ruby on Rails is an open source programming language that provides a code stage to quickly build database-driven web applications.
It includes five standard packages:
ActiveRecord, ActiveResource, ActionPack, ActiveSupport and ActionMailer that can be extended. The Rails framework, which provides the structure for the models and views needed for a basic website, is developed employing the Model-View-Controller (MVC) architecture.

There are two concepts in Ruby on Rails--Convention over Configuration (CoC) and Don't Repeat Yourself (DRY).
The principle behind COC is that only strange aspects of the application need to be specified; otherwise, they follow the established standard.
DRY requires that information be placed in a single, unambiguous location to ensure a single point of reference and avoid hidden errors.

The principles behind Ruby on Rails allow for huge development speed while minimizing lines of code and errors. It has the advantage of including a lot of web development know how from its inception, which makes it simple to use, maintain, and extend.

Ruby on Rails is now widely embraced as a great tool to rapidly build scalable, database-driven web applications.

DNS Security Issues (Misconfigurations)

DNS fall with security issues in a relation to:

Service/traffic redirection:

DNS requests(traffic) to any site, could be redirected to an IP address of a malicious attacker’s site using man in the middle attack or any other type of attacks.
As a user, you should verify the authenticity through cryptographic signature hashes even with trusted sites.
Similarly, name servers with MX records can be modified to redirect
e-mail from one domain to another.



Denial of service:

Instead of redirecting records elsewhere, they can be redirected to 10.1.1.12
or any another address range that does not exist which may deny legitimate target from being reached.


Zone transfers:

Domain record exchanges such as updating information across name servers can reconfigure packet routing across a network.

Past versions of name servers had no security, and anyone with access to programs like nslookup and dig were capable of issuing them.

DNS zone transfers should only be allowed between DNS servers and clients that actually need it.
DNS master is only transmitting zone information to (and only to) the IP addresses of slave-1/2..etc DNS servers, slave should not transmit to anyone in most configurations.

Also protection with zone transfers can be obtained by implementing DNS keys and even encrypted DNS payloads.

Else than that Instead of limiting transfers purely based on IP address, sites can maintain cryptographic signatures or relies on public key cryptography as in DNS security extensions (DNSSEC)


Predictable query IDs:

A query ID is included within a packet to uniquely identify sessions, such a query within a request is a security issue that allows an attacker to poison domain name server caches with forged address resolution information, a way to reduce the breadth of this attack random query IDs is used.

Secure How-To: Not only

-Using complete physical separation of internal recursive queries and external public name service to prevent DNS cache poisoning.
-Also securing dns could be by redundancy and load balancing which in turn requires that networks house more than one DNS server.

E-mail Risk ( Data vulnerabilities )

As a universally implemented protocol, email should be a target
for attacks and risk ; due to the very sensitive nature of the data or information that is transmitted.

E-mail at its core is safe because it does not transmit directly executable(binary) code.
But an e-mail client starts adding features to be more of a collaboration tool, such as Outlook which embed malcode that has chances of being decoded and launched.

An e-mail protocol like Post Office Protocol (POP), was used in the clear,
which means when a mail was received, it was transmitted with the POP3 protocol.
In such case, the entire e-mail fit into one packet and opportunity to capture packets and read e-mail content isn't off-topic.

Capturing and modifying of e-mail can be done either as a man-in-the-middle attack (using ARP spoofing tool, such as ettercap) or as a replay attack.

Man-in-the-middle attacks are best avoided by using encryption and digital signing of messages.

On the other hand, Spam DoS attacks are a result of spammers using false domains in the e-mails they send.
The most danger type of these attacks is when a spammer forges an address.

Spam attacks avoided by referencing a blacklist which is a database of known internet addresses (by domain names or IP addresses) used by spammers.
Blacklisted addresses return invalid responses so the server rejects the e-mail.


Proper e-mail authentication is also a security concern.

-Login authentication : user name and password passed separately encoded with base64.
The user name and password are then used to authenticate to the mail server.

- onPOP before SMTP : preventing spammers from using a mail server relay.
SMTP relaying is permitted by an IP address if that IP address has participated in a valid POP session in the prior X minutes.
The POP protocol requires a valid password so spammers will not be able to use POP prior to using the mail server for relaying.

A mail relay sits in the DMZ outside the perimeter firewall with a benefit having all mail received first by this mail relay which can check for unwanted scripts, viruses, and questionable attachments and also a good place to put spam protection, such as blacklist monitoring and spam filtering.

Securing e-mail traffic: discussed previously
Creating a secure tunnel for using less secure e-mail protocols can be a strong method of protecting the privacy and integrity of the e-mail.
With an SSH tunnel, we can still have the protection of the SSH encryption, in SMTP/POPing.

Later talking about SPF, DomainKeys ...etc

UNIX/Linux as a poor vulnerability target

UNIX has some characteristics that make it less attractive for security attacks

Unix is still primarily used on different platforms.
This use, make the average UNIX user more knowledgeable about the operating system and security.

There are many scripting techniques in UNIX.
Unlike Windows, the scripting is not integrated into applications (such as Outlook and Word).

In UNIX, scripts can be integrated into applications such as mail and word processing, but not to be _the default configuration_.

This makes UNIX much less vulnerable than a Windows system that is running Outlook and allows users to commonly run Visual Basic scripts.

Also the inability of a common user to alter an executable is a severe restriction on viruses and worms that depend on users to propagate their malware.

On the other hand in Unix, Physical Security is somehow perfectly controlled:
(monitoring hardware changes)
A software tool library like kudzu, detects and configures new and/or changed hardware on a RedHat Linux system and currently ported to different other distros.

What's notable that it detects the current hardware and checks it against a database stored in /etc/sysconfig/hwconf, which mean it can be an eye on system hardware monitoring any changes.

Another piece in Unix is its partitioning of disks and file systems which can be a physical security issue.

File systems, such as ext3 in Linux, use journaling to make the recovery of damaged file systems more reliable.

Journaling provides for a fast file system restart in the event of a system crash, using database techniques, journaling can restore a file system in a matter of minutes, or even seconds.

Not finished yet....

Securing communication protocol traffic (SSH tunneling).

A useful option for secure communication between client/server is to tunnel the communication inside the Secure Shell protocol (SSH).

It can be used to tunnel POP3 and SMTP traffic using ssh.
-Sure u must have both ssh client and ssh server installed on the two ends.
-Create a local ssh tunnel on local machine (ex.port 5110) to the POP3 server's port 110 or SMTP 25
# ssh -f -N -L 5110:localhost:110 user@POP3_server

Or even simply binding to a privileged port (110, the POP port)

# ssh -L 110:mailhost:110 -l user -N mailhost

Same, you can also forward SMTP for outgoing mail (port 25), single ssh line can have multiple -L entries, like this:

# ssh -L 110:mailhost:110 -L 25:mailhost:25 -l user -N mailhost

-U can still check for port forwarded :
Telnet localhost (forwarded port)/
You should see the POP3 server's banner information.

-Finally you have to configure your mail client to access your mail via POP3 using mail server localhost and desired forwarded port.

Home network map modification ( somehow mobility)

I modified my home network somehow to give myself a way to have mobility around ;).

- Firing dhclient on Nixbox ==> IP obtainable automagically
- /etc/network/interfaces modifications
- Downing default gw
- Winbox --(Wlan/Wlan Ad-Hoc)--> NixBox ----> Router
- Firing ipmasq without firewall-configs (dpkg-reconfigure ipmasq)
- Winbox <--(Wlan(192.168.0.1)/Dns <> IPmasq)--> NixBox (Nix Connection masq)
- Noticed.., neither Bind(named) nor DNSmasq is needed, by default named installed.
- Apache/httpd port 80 --NAPT--> 192.168.0.1 <--(inside).

A long time i wondered to furnish this modification, finally ...

"_Someone i have lost long time ago_" Comment.

If you have lost someone close to you, how do you deal with the toughest moments
that hit you and don't always give you warning?

Sadness and suffering make people wiser -
Sadness and suffering will follow us as long as we live -
If you can no longer feel these emotions, it's a sign that you have
stopped growing as a person.
Sadness and suffering enable us to be strong enough to be kind to others.

When a loved one is gone, you'd look for his or her image in everything that you see,
and everything that's within you seek an exact image of how you'd like to see your loved one again, pay an attention when you love again to the one you are loving, as not being your loved one substitute.
Take a good look around you: paying too much attention to what you have lost, lets you neglect what you have/in now.
Look into the bottom of your soul and find what you really need.

Think of loving, and not of being loved.
If there is someone who is in more pain and sorrow than you are,
Give him or her your loving hand and warm support...
feel to be felt...
You have the ability to comfort others to become comforted

A Long time away:

But there's something happening in me

Simple rules of cooperation with what's nearby lead to unexpected, even startling complexities that you could not have predicted from the rules (emergent phenomena). This is a neat parallel to the way that startling and unexpected phenomena like open-feeling emerge in me.

Today's mood

Always _he_ insists and will insist on __it__ , "He's rude, impoliteness and indecency "

-I'm thinking ..., i have an educated mind to be able to entertain __this thought__ or this insistence without accepting it.

-To conclude, strike or to reach an agreement concerning duties, isn't off-topic;
It's even a better way.

-Silly to put all that effort into something that's just going to die, but factual.

-Cases with similarities, but which one that really deserves ????

-For who knows what is good for mortals while they live the few days of their vain life?

"Discordianism" believes or apophenia phobia ...?

-Is it a challenge of chance to correlate incidents to
"Law of Fives", "The Law of 23s" and "The 23 Enigma" ?


Why 23 is an enigma ?

- Cosmic number ?

- Applying the experience of seeing patterns or connections in random or meaningless data ?

- A suspense was in the Bible reads: "and be sure your sin will find you out", Numbers 32:23

- Also this number has some unique features : 2/3 = 0.666 & 2*3=6

- I don't care about Discordians and there believes maybe it's somehow interesting.

Anyhow :) i see it interesting for myself to use apophenia discovering the theory: Complete mathematical disorder in any physical system is an impossibility.

Common experience along the nights

-Long nights with a compelling sense of familiarity, and also a sense of "eeriness", "strangeness", or "weirdness".

-Following the same path,

-Be far from the conscious mind.

-Déjà vu, Déjà senti et Déjà visité.

Google Interview

-I never applied. Google contacted me, and asked me to interview. I agreed, only after explaining that I was very happy where I was and that I was very unlikely to move.

-Basically, Google does not care about your current skills, what you have done or even who you are. They have some sort of a glass shoe and try to see if your foot fit into it.

-Still i have to set the second interview.

Strange Dream

I t was yesterday .

A strange dream , I'll post it in few points , but firstly i want to mention that it's a symbolism.

-Drunk friend by my wine bottle , faced a battery.
-A young girl fights to see a police major.
-Underground road event full of strange shape of drunk ppl and me inside it with noway out.
