Re: exchange like alternative

2012-12-04 Thread Justin Jereza 
I've been using Zimbra for the past 4 years now and it's been pretty solid.
I think they stopped providing packages for Debian though.

Re: Best remote control software

2012-01-11 Thread Justin Jereza 
 I was just wondering what is the best software solution available.
 Otherwise I might invest in a KVM switch.

If you just need the apps that run on your Linux PC but don't need the
desktop environment, you might want to look at xming, an xserver for
windows. I've used it before and it worked great for me.

You'll end up with your linux apps showing up as just another app window
but running on the linux box.

Re: grub-pc mdadm root

2012-01-10 Thread Justin Jereza 
 Some searchs talk about a separate /boot partition - I don't
 understand why that is needed or relevant.

 I'm assuming I'd make a mdadm v 1.2 raid 1 partition for root.

Your /boot must be in a regular partition or in a raid1 volume. It may
either have it's own filesystem (I typically use one that's 512mb in size)
or in the root filesystem. If it's in the root filesystem, then that means
that root should be in a regular partition or in a raid1 volume.

I typically put /boot in raid1 then create a raid5/6 volume, then I create
lvm volumes that use the raid5/6 volumes.

Re: grub-pc mdadm root

2012-01-10 Thread Justin Jereza 
 With grub2, your /boot can be an LV on a RAID6 if you want it to be.
 The only thing that does not work is /boot on dmcrypt.

I forgot about grub2. It's only recently that I've built it and seen how
big of a monster it is. All the modules it comes with is quite useful
though.

 Having /boot on a separate RAID1, however, might be easier for
 recovery,

That's true.

Re: Two node storage failover with lvm and ISCSI

2011-02-18 Thread Justin Jereza 
 we have two nodes connected to one big SAS storage (LSI 630j Jbod) with
 SAS HBAs and they can see all disks at same time.
 Now we want build a failover construct for lvm with ISCSI:

 LSI Jbod - node* | raid | lvm | ISCSI - Global IP - Client

 If the primary node fails, start raid on node two, activate lvm, export
 them via ISCSI, take over the IP address.

 There are many layers, that can fails, like raid, lvm, timing 

 any suggestions?

Bugger. I always fail at replying to mailing lists using GMail. Repost.

I'd consider running clvm + gfs2 instead. That way, both nodes can
stay up and connected to the same filesystem at the same time. The
only decision left would be which node to use. OTOH, you can have an
HA configuration as well.

IP masquerading doesn't work on linux-image-2.6.24-etchnhalf.1-686

2009-06-26 Thread Justin Jereza 
Hello.

I just upgraded my kernel to linux-image-2.6.24-etchnhalf.1-686
because gdb was printing the error message Failed to read a valid
object file image from memory. and breakpoints jump around when I try
to debug something. According to
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=401482 this is a bug
in linux-image-2.6.18-6-k7.

The problem is, IP masquerading doesn't work when booting the
etchnhalf kernel. Is there any way to fix this? Attached is my dmesg
and iptables rules, if that information is required.

Thanks!

Re: aptitude --purge

2008-08-31 Thread Justin Jereza 
 The following packages will be REMOVED:
  telnet{a} - also purge instead of removing. I.e., nothing like
 APT::Get::Purge. The undocumented --purge doesn't work like apt-get's.
 One must follow with a
 # aptitude purge ~c
 to clean up the mess.

If I understand you correctly, you want all automatically removed
packages to get purged instead. I have the following in my
~/.aptitude/config to do just that:

Aptitude ;
Aptitude::Purge-Unused true;

IPv6 configuration in /etc/network/interfaces doesn't work on bootup

2008-05-07 Thread Justin Jereza 
Hello.

I've got the following in my interfaces file:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
address 192.168.5.1
netmask 255.255.255.0
gateway 192.168.5.254
dns-nameservers 192.168.5.254
iface eth0 inet6 static
address fc00::1:1
netmask 7

Anybody got any ideas why the IPv6 address doesn't get assigned to
eth0 on bootup?

ifconfig eth0 add fc00::1:1/7 works fine after bootup.
