Searching on google http://tinyurl.com/d5ulkpr
i've found only about installation on ipad or other f***ng smartphone, problem seems to be fastlib that is lost.
My bbox is up to date, and msf is "Aggiornato alla revisione 16070."
I've also tried to update rubygem with:
Code: [Select]
gem install rubygems-update
gem updatebut nothing change, any idea guyz?
perhaps I can't see the solutions??
I've forget some useful info??

Hi bro,

Try to install : gem install rubyzip

If this don't help, try SVN update :

cd /opt/backbox/msf
svn update

Sometimes after updates metasploit give errors, and if you run update few hours after,  problems stop. It's all about MSF repo, they make a lot of updates, but they don't test or explain them to free users.

I see now, i made update right now after 24 days :), but theire repo version was update 14.11.2012, not sure why your system don't load. When this happen to me i check modules files and if some gem is not installed that can make problem, but don't worry bro, next update will fix your issue :), hope that you can wait.

Code: [Select]
sudo apt-get -y install ruby1.9.1
sudo apt-get -y install ruby1.9.1-dev
sudo gem install rubygems-update
sudo gem update


again i don't know what backbox is running  im guessing 1.9.3  make sure you using the right ruby-rvm 1.9.3 is faster and more affective or should i say efficient at loading the modules faster  

Metasploit do let modules out sometimes with some import errors and have many a time had to fix them within the modules

but in this case that was'nt the issue !!!!

AND while I'm on the point !! if you having an issue with a certain gem remember while it will install the latest gem by the above You may also have an early version that will cause a conflict
 
example :
Code: [Select]
sudo gem install nokigiri --version "number"

Code: [Select]
sudo gem uninstall nokigiri

this will then ask .. if there is two installed  do you want to remove x or x & y { versions } .. example !! then you can remove both then  and use the below to update to the latest  

Code: [Select]
sudo gem install nokigiri
to install the latest


and etc etc blah blah gem dep etc etc and look up man gem etc .. search for whats in the gems database etc etc ..ok im getting bored listening to my self now !!!

I might as well finish what I started

so if you need to get lets say a version that is the latest or whatver

Code: [Select]
sudo gem search --remote nokigiri | sort -n | tail -1

etc etc you can use grep , awk ,sed what ever you like or makes you happy  ;D



But if you have an issue post and the guys will help !!!!

hey ostendali

Code: [Select]
sed '371,391!d' /opt/backbox/msf/lib/fastlib.rb > $HOME/fastlib.txt

if its a faulty gem in metasploit or corrupt just remove the folder and do msfupdate .. remove the gem or folder
removing the folder will replace the folder all the files in that folder

Code: [Select]
sudo rm -rf  /opt/backbox/msf/lib/fastlib.rb

if it persists !! then check out that gem or the module that is giving problems

As Far as i can see he has weVeg has got it sorted

I can't understand the last robert's reply... Sorry bros but till yesterday's update msf worked fine, so, imho, there is a oversight on msf code

As you can see yourself the fastlib.rb has been modified yesterday.......
so, follow the r083rt suggestion by removing the library dir and do an update...

Probably something went wrong when you have updated and the library corrupted...

ok i'll try!!
Thank you a lot!!!

EDIT:
removed the folder, and while updating for the first time:
Quote
svn: REPORT di '/svn/!svn/vcc/default': Impossibile leggere il corpo della risposta: Connessione sicura terminata (https://www.metasploit.com)

second time:
Quote
svn: access to '/svn/framework3/branches' forbidden
I'm not very lucky in this day :/

thanks zerof and ostendali for you input excellent stuff and taking the time to search the database on the fastlib import updates !!!

weVeg if you have problems with Metasploit these are the first things you do

1 ) remove that folder what lists the gem or modules and do an msfupdate
2 ) if it persists i.e like an import error i.e the devs appended the file or either upgraded and it conflicts with another module
     then either ..fix it your self by looking at the problem i.e output error TRACE THE FILE AND IMPORTS and examine the file
     OR if you cant figure the problem out look up the latest version and compare it to yours ..


sometimes its a case of fix it yourself as when theres a problems the devs don't catch it quick enough or get delayed on it
My experience in the pass was never to wait for the devs as sometimes it was taking too long so I always fixed it myself

once again thanks ZeroF and ostendali .. quick response and perfect input ... as usual nothing strange   ;)

sorry weVeg  IF the post was hard to understand   ;D THE FORMAT was not as clean as it should have been My fault Not yours

Im in the middle of getting a full svn refresh from source if can wait ill zip the lib folder and upload it for you

if you want a pacific  folder or file do this

Code: [Select]
svn checkout https://www.metasploit.com/svn/framework3/trunk msf --depth empty
cd msf
svn filename or folder
### then just move the file or folder you svn'ed and move it to the location i.e /opt/backbox/msf/ etc etc


ok I uploaded the files for you ..from a fresh svn source !!

here is the fastlib file  fastlib.rb link removed by r083rt
here is the lib folder lib folder link removed by r083rt

Code: [Select]
cd Downloads
tar -xf lib.tar.gz
sudo rm -rf /opt/backbox/msf/lib
sudo mv  lib /opt/backbox/msf



svn is very slow the project would be better moving to git .. git is better in many ways
