sedmičkové akordy 
II-V-I dominantní jádro ¨

X /\ = Xmaj = Xj = velká 3, velká 7 (půltón od root), a 5 nebo 6, velká 9
X-7 = Xmin7 = Xm7 = malá 3, malá 7 (celý tón od root), a 5 nebo 6, velká 9
X7 = Xdom7 = velká 3, malá 7 (celý tón od root), a velká 6 nebo velká 9
Xsus7 = X7sus4 = velká 3 zvýšená o púltón, malá 7, velká 6, velká 9

akord se staví od 3 nebo 7 stupně

tritónová subsituce

Chord substitution often results from an attempt to provide smooth voice leading. Using the tritone substitution, the roots of the ii-V-I progression move down by half-steps, instead of ascending 4ths. For example, in the key of C the progression becomes Dm7, Db7, CM rather than Dm7, G7, CM.

Refresh screen with [ ctrl + l ] when garbled  
for example, when you are at the console in mc, copying files, and some kernel event is put on screen then it helps to get out the mess

XEN: increasing the number of veth/vif pairs and the number of file loopbacks  
increasing the number of veth/vif pairs, may be ignored by modprobe since 5.3

increasing the max number of file loopbacks (/dev/loop*)
options loop max_loop=32


the option of /etc/modprobe.conf
# cat /etc/modprobe.conf

Linux: RBL (blacklisting) and preventing spam in Zimbra 
If you need to improve the antispam performance of Zimbra suite then the adding a few more settings could be helpful.

the defaukt zimbraMtaRestriction policy is set as below:

[linux ~]$ zmprov gacf | grep zimbraMtaRestriction
zimbraMtaRestriction: reject_invalid_hostname
zimbraMtaRestriction: reject_non_fqdn_sender


I'm using this:

[zimbra@linux ~]$ zmprov gacf | grep zimbraMtaRestriction                        zimbraMtaRestriction: reject_invalid_hostname
zimbraMtaRestriction: reject_non_fqdn_sender
zimbraMtaRestriction: reject_non_fqdn_recipient
zimbraMtaRestriction: reject_unknown_sender_domain
zimbraMtaRestriction: reject_unknown_recipient_domain
zimbraMtaRestriction: reject_unauth_pipelining
zimbraMtaRestriction: reject_unauth_destination
zimbraMtaRestriction: reject_rbl_client bl.spamcop.net
zimbraMtaRestriction: reject_rbl_client sbl.spamhaus.org
zimbraMtaRestriction: reject_rbl_client cbl.abuseat.org
zimbraMtaRestriction: reject_rbl_client dul.dnsbl.sorbs.net


to set the values use the following command:
[zimbra@linux ~]$ zmprov mcf zimbraMtaRestriction reject_invalid_hostname \
zimbraMtaRestriction reject_non_fqdn_sender \
zimbraMtaRestriction reject_non_fqdn_recipient \
zimbraMtaRestriction reject_unknown_sender_domain \
zimbraMtaRestriction reject_unknown_recipient_domain \
zimbraMtaRestriction reject_unauth_pipelining \
zimbraMtaRestriction reject_unauth_destination \
zimbraMtaRestriction "reject_rbl_client bl.spamcop.net" \
zimbraMtaRestriction "reject_rbl_client sbl.spamhaus.org" \
zimbraMtaRestriction "reject_rbl_client cbl.abuseat.org" \
zimbraMtaRestriction "reject_rbl_client dul.dnsbl.sorbs.net"


to turn on antispam filtering in zimbra (SpamAssassin):
zmlocalconfig -e amavis_dspam_enabled=true


reccomended reading

XEN bridging by system, instead of using /etc/xen/scripts/*wrapper* 
get vlan
/etc/sysconfig/network-scripts>cat ifcfg-bond1.x
DEVICE=bond1.x
BOOTPROTO=none
BRIDGE=xenbr1
ONBOOT=yes
VLAN=yes


just a bridge
/etc/sysconfig/network-scripts>cat ifcfg-xenbr1
DEVICE=xenbr1
TYPE=Bridge
BOOTPROTO=none
ONBOOT=yes
DELAY=0
NM_CONTROLLED=no

with ip

/etc/sysconfig/network-scripts>cat ifcfg-xenbr0
DEVICE=xenbr0
TYPE=Bridge
BOOTPROTO=none
IPADDR=X.X.X.X
NETMASK=255.255.255.0
ONBOOT=yes
DELAY=0
NM_CONTROLLED=no
