Hi --

I forgot to remove an LVM snapshot after making a backup.  Now neither
the snapshot nor the original volume are available.
How do I recover and get the original volume back online?

Currently, the output of lvs looks like

  LV               VG         Attr   LSize   Origin    Snap%  Move Log Copy% 
......  
dom5_data VolGroup01 -wi-ao 10.00G
domTemplate_data VolGroup01 -wi-a- 2.00G
  dom6_data        VolGroup02 owi-i-  24.00G                                 
  dom6_snap        VolGroup02 swi-d-   1.00G dom6_data 100.00  




Any help very much appreciated!

This is on a Dell 2950 with CentOS 5.0 running Xen

Tim,

The important ones, imho --
1. disallow root login
2. disallow password authentication (use keys, as someone else has
described)
3. prevent multiple failed attempts using iptables:
# Log and block repeated attempts to access SSH
# See /proc/net/ipt_recent file for low-level data
# Block attempts to access SSH if 4 or more attempts made in the last 60
secs
-A RH-Firewall-1-INPUT -p tcp --syn --dport 22 -m recent --name
sshattack --set
-A RH-Firewall-1-INPUT -p tcp --dport 22 --syn -m recent --name
sshattack --rcheck --seconds 60 --hitcount 4 -j LOG --log-prefix "SSH
REJECT: "
-A RH-Firewall-1-INPUT -p tcp --dport 22 --syn -m recent --name
sshattack --rcheck --seconds 60 --hitcount 4 -j REJECT

4. if possible, limit ssh access to your static ip.

That all seems reasonably secure to me!

Yeah, I resolved that problem when I switched ISPs recently by using
something like this:

Does eula stand for End User Licensing Agreement, perhaps?  Just a guess.
If it's a script why don't you just look in it (the calling script) and
see what it's doing?
Also, maybe the eula binary exists (did you look for it?) but is not
executable, which should be easy to fix.

Okay, thanks for the tip!  Do the freenx rpm distributions for 64-bit
contain the 32-bit ones (seems like they should if they are required) or
do I have to install the 32-bit rpms separately? I'm sure I can figure
this one out, but if you happen to know, do tell!
