3PAR Port port:0:0:2 Port listed as host path but is State:ready, Mode:initiator and Type:rcfc

 Assuming, that RCFC is properly configured and Zoning is correct (Only the 2 RCFC Ports in the Zone).

To check this use: showportdev ns 0:2:2

You should see only the two RCFC WWN, so where are the Hosts come from?

The Issue is, that the Array holding a List of all Hosts ever seen on the Ports.

The message says, that on these ports Hosts are seen (also in the past), but it is an RCFC port that should not see Hosts.

Check the Host list with: servicehost list

Cleanup all old Hosts with: servicehost remove [-f 0:2:2]

FATAL: Could not load /lib/modules/*-openvz-*/modules.dep: No such file or directory

Hi all, if you have problems with openvz and iptables fatal message, there is solution:

run command

depmod

it will return something like this

WARNING: Couldn't open directory /lib/modules/2.6.32-5-openvz-amd64: No such file or directory

FATAL: Could not open /lib/modules/2.6.32-5-openvz-amd64/modules.dep.temp for writing: No such file or directory

so create directory

mkdir /lib/modules/2.6.32-5-openvz-amd64

and run command again

depmod

ls -la /lib/modules/2.6.32-5-openvz-amd64/

How to unbind port

From time to time apache after restart doesn't close used ports and You have to restart server. This we don't want. Solution is pretty simple:

find process IDs

$ lsof -i TCP:80

output:

apache2 16442 www-data    3u  IPv4 1158908      0t0  TCP s0.domain.tld:80 (CLOSE_WAIT)

...

then we kill process(es)

$ kill -9 16442

MEC TM1701M or JP108-A

dropbear make pub key

4 Steps:
a) Generate private rsa key in a file: dropbearkey -t rsa -f /etc/dropbear/dropbear_rsa_host_key
b) Generate public rsa key in a file: dropbearkey -y -f /etc/dropbear/dropbear_rsa_host_key | grep ssh-rsa > /tmp/dropbear_rsa_host_key.pub
c) Copy the public key to the server: scp /tmp/dropbear_rsa_host_key.pub haritz@192.168.111.253:/home/haritz/.ssh/authorized_keys
d) scp or ssh indicating the path of the 'identity_file': ssh -i /etc/dropbear/dropbear_rsa_host_key haritz@192.168.111.253
The identity_file is needed (at least in my case).
