libisc50 probléma backports-os frissítésnél

It looks like an old version of libbind is left installed, which depends
on an old version of libdns which depends on the conflicting version of
libisc. So basically what I did is I looked at what packages conflicted
when trying to remove libisc50, and removed them as well. That normally
can quickly get ridiculous, since eventually you will run into a package
that depends on a lot of others, but since nothing seems to be using the
libbind9-50 package, it's a pretty clean fix.

Probléma megoldása
apt-get -f --purge autoremove libisc50-
apt-get -f --purge autoremove libisc50- libbind9-50- libisccfg50- libdns53- libdns55- libisccc50-

Using iSCSI On Debian Lenny (Initiator And Target) 

Egy egyszerű módszer iSCSI target használatára

     

This page provides some information on how to use IET on Debian. ( iSCSI Enterprise Target is known as iscsitarget under Debian). reminder, the target is the name of the "server" under iSCSI terminology (i.e The one that actually have the disk).   

 

Quickstart

  

 

1. Install IET's package and module

 

IET is made of two packages :  

 

2. Configure

 

You need to configure /etc/ietd.conf (here's a simple test page).  

  •                                 
     # Example iscsi target configuration
 
 # a first account
 IncomingUser jdoe YourSecurePwd1
 # another one, for a windows user.
 IncomingUser iqn.1991-05.com.microsoft:JDOE-PC YourSecurePwd2
 
 #If mutual CHAP shall be employed, you need
 OutgoingUser jack YourSecurePwd2
 
 # The target name must be a globally unique name, the iSCSI
 # standard defines the "iSCSI Qualified Name" as follows:
 #
 # iqn.yyyy-mm.<reversed domain name>[:identifier]
 
 Target iqn.2007-01.org.debian.foobar:mydisk1
         IncomingUser joe YourSecurePwd1
         OutgoingUser jim YourSecurePwd2
         #make sure the partition isn't mounted :
         #Lun 0 Path=/dev/sdh,Type=fileio
 
 
 Target iqn.2007-01.org.debian.foobar:CDs
         IncomingUser joe YourSecurePwd1
         OutgoingUser jim YourSecurePwd2
         #make sure the partition isn't mounted :
         Lun 0 Path=/dev/scd0,Type=fileio,IOMode=ro
         Lun 1 Path=/dev/scd1,Type=fileio,IOMode=ro
         #Lun 2 Path=/dev/hdX,Type=fileio,IOMode=ro
         Lun 3 Path=/srv/debian-20070313-kfreebsd-i386-install.iso,Type=fileio,IOMode=ro
     

    You should refer to the ietd(8) and ietd.conf(5) manpages for more information.   

 

3. Restart the daemon

 

  •   
     invoke-rc.d iscsitarget restart
      

    That's It ! you can use it.   

 

Online administration / Dynamic configuration

  

 

Adding a target / LUN

 

First, Let's add a Target.  

  •   
     ietadm --op new --tid=[id] --params Name=iqn.foo.bar:test1
     

[id] must be unused. You can get a list of the currently used Target IDs by: cat /proc/net/iet/session   

Then add a LUN to a pre-existing target.  

  •   
     ietadm --op new --tid=[id] --lun=[lun] --params Path=/path/to/exported/file,Type=fileio
     

[id] must be an already existing Target ID (listed in /proc/net/iet/session)   

refer to the manpage on how to disconnect a connexion, change the settings or remove a LUN or a target.   

 

Adding a user

 

  • If you use mutual CHAP authentication, you also need to configure --params=OutgoingUser=foobar user.  

First, create a user for "discovery" :  

  •   
     ietadm --op new  --user --params=IncomingUser=jdoe,Password=Compl3xPassw00rd
      

Then, create a user for "iqn.foo.bar:test2" :  

  •       
     cat /proc/net/iet/session 
 tid:1 name:iqn.foo.bar:test1
 tid:2 name:iqn.foo.bar:test2
 
 ietadm --op new --tid=2 --user --params=IncomingUser=jdoe,Password=Compl3xPassw00rd
      

refer to the manpage on how to "delete" a user.
