Just for tests, we assembled a “miner” with cheap hardware.Our configuration is consist of
-motherboard ASUSTeK P5KPL-CM
-cpu model name : Intel(R) Core(TM)2 Duo CPU E7300 @ 2.66GHz
-ram : 2x2048mb ddr2 800mhz
-gpu : gigabyte radeon r9 270(2048mb gddr5) costs 341 BGN with VAT included
-power supply : corsair cx600 costs 145 BGN with VAT included

The linux distribution which is used here i BAMT

500 OOPS: vsftpd: refusing to run with writable root inside chroot()

During the setting up vsftpd(2.3.5-3) daemon in Debian Wheezy, I found the following error 500 OOPS: vsftpd: refusing to run with writable root inside chroot() when you try to open ftp connection to the server.This appears when chroot_local_user=YES option is enabled in /etc/vsftpd.conf.Many people had the same problem.This is BUG which is already reported.We can fix this problem with additional patch.

vim /etc/apt/sources.list

add
deb http://ftp.cyconet.org/debian wheezy-updates main non-free contrib

apt-get update


aptitude install -t wheezy-updates debian-cyconet-archive-keyring vsftpd

vim /etc/vsftpd.conf
add

allow_writeable_chroot=YES

service vsftpd restart


root@debian:~# dpkg -l | grep vsftpd
ii vsftpd 2.3.5-10~update.1 i386 lightweight, efficient FTP server written for security

snmp Call “HostServiceSystem.Start” for object “serviceSystem” on ESXi “” failed.

During the snmp daemon enabling in vmware esxi 5.5.0 the following error appears.

We have to enable snmp service in /etc/vmware/snmp.xml , log through in ssh and

~ # vi /etc/vmware/snmp.xml

this is the default content

<config><snmpSettings><enable>false</enable><communities></communities><targets></targets></snmpSettings></config>

change

<enable>false</enable>

to

<enable>true</enable>

also we can add and snmp community

<communities>public</communities>

restart all the services

/sbin/services.sh restart
