error di event viewer
The description for Event ID 0 from source Cygwin cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
dari sisi client, walaupun sudah diarahkan ke proxy, tp tidak bisa terhubung ke internet.
cache log awalnya seperti ini
#cache_dir aufs /cygdrive/d/squid/cache 3000 16 256 (default)
diubah menjadi ini cache_dir aufs /cygdrive/c/Squid/var/cache 10000 16 256 tapi masih error.
lalu diperbaiki menjadi ini.
cache_dir aufs /cygdrive/c/squidcache 10000 16 256
sebelumnya membuat folder squidcache di drive C, lalu compile ulang dan restart
perintah lainnya.
squid.exe -N -d1
squid -z
squidclient.exe http.google.com
squid.exe restart
arp -a

landasi kehiupan dengan beriman kepada allah, kalo iman sudah menjadi landasan kehidupan, maka allah akan memberikan kehidupan yg baik.
1. barang siapa yg beramal soleh dalam keadaan beriman, allah akan memberikan kehidupan yg baik.
melaksanankan perintah dan menjauhi larangan, jika sudah dilalui maka akan naik menjadi orang yg bertakwa
2. siapa yg bertawa pada allah, maka diberikan rizky dari arah yg tidak disangka2 dan allah akan memenuhi seluruh kebutuhan hidupnya.
kesimpulan,
1. orang beriman akan diberikan kehidupan yg baik
2. orang bertakwa akan diberikan kehidupan yg baik dan rizky dari arah yg tidak disangka-sangka

ini yg menyebabkan opnvpn gak jalan, ternyata protokol yg berbeda antara modem dan konfigurasi server.conf dan modem
dalam modem protocol TCP
<vrtSrvEntry id=”2″ instanceId=”2″ state=”enable” name=”VNC” addr=”192.168.7.50″ protocol=”TCP” eStart=”1194″ eEnd=”1194″ iStart=”1194″ iEnd=”1194″ leaseDuration=”0″ remoteHost=”0.0.0.0″ iptschedid=”-1″/>
sedangkan konfigurasi UDP
jadi harus disamakan.

CentOS 7.x
Although CentOS 6.x Instructions will work for CentOS 7.0, you could upgrade the installation process to be completely CentOS 7.0 compatible:
yum install yum-cron
systemctl disable yum-cron.service
systemctl stop yum-cron.service
.conf file (Configuration) located at: /etc/yum/yum-cron.conf AND /etc/yum/yum-cron-hourly.conf.
Note that in contrast to CentOS 6.x, by default yum-cron only download updates once a day and doesn’t apply them. change to:
apply_updates = yes
In /etc/yum/yum-cron.conf if you wish to. make note that you can now define hourly updates in the /etc/yum/yum-cron-hourly.conf file.
mencari dan mengumpulan file *.thor lalu memindahkan file tersebut dengan nama file-jahat2.txt
#find / -name “*.thor” > file-jahat2.txt
lallu menghapus file tersebut secara sekaligus.
for f in `cat file-jahat2.txt`; do rm “$f” -rf; done
atau cara simple nya adalah menghapus secara otomatis semua file dengan extention locky dan thor disemua folder
find / -name “*.locky” -delete
find / -name “*.locky” -delete
Mencari email history di zimba adalah sebagai berikut.
Penerima (-r = Recipient address)
#/opt/zimbra/libexec/zmmsgtrace -r penerima@email.com /var/log/maillog-20161226
Pengirim (-s = Sender address)
#/opt/zimbra/libexec/zmmsgtrace -s pegirim@email.com /var/log/maillog-20161226
menggunakan file gz
/opt/zimbra/libexec/zmmsgtrace -s pegirim@email.com zimbra.log-20170113.gz
-h (help)

https://wiki.zimbra.com/wiki/Specific_Whitelist/Blacklist_per_IP
With ZCS 8.5 and later, it is possible to maintain an IP blacklist for connections to Postfix. This is useful in DoS and targeted spam attack scenarios.
Many clients use RBLs to block spammers from flooding their MTAs with spam. Unfortunately, perfectly valid sites occasionally end up on these lists. With ZCS 8.5 and later, it is possible to create an on-disk database map that allows the client to whitelist specific blacklisted IPs so that emails from those IPs still get delivered.
Whitelist Edit /opt/zimbra/conf/postfix_rbl_override. Add IP address(es) SPACE OK to the file, one IP address per line:
1.2.3.4 OK
Run the postmap to save and apply the changes in Postfix:
postmap /opt/zimbra/conf/postfix_rbl_override
Run the zmprov to apply the changes to the Zimbra Collaboration Server:
zmprov mcf +zimbraMtaRestriction 'check_client_access lmdb:/opt/zimbra/conf/postfix_rbl_override'
postmap will need to be rerun on the file any time an IP address is added or removed.
Blacklist Edit /opt/zimbra/conf/postfix_blacklist. Add IP address SPACE REJECT to the file, one IP address per line:
1.2.3.4 REJECT
Run the postmap to save and apply the changes in Postfix:
postmap /opt/zimbra/conf/postfix_blacklist
Run the zmprov to apply the changes to the Zimbra Collaboration Server:
zmprov mcf +zimbraMtaRestriction 'check_client_access lmdb:/opt/zimbra/conf/postfix_blacklist'
postmap will need to be rerun on the file anytime an IP address is added or removed.
