You can use Task scheduler to run powercfg.exe
use a command window to run powercfg /? so you can see the various commands available
running powercfg /l lists the codes “GUIDs” for your power schemes
running powercfg -s
I assume you are running Win7 [I think these items are the same in Vista but cannot check].
Does the IP you’re connecting from have reverse DNS on it?
When you connect to SSH, By default it will try to do a DNS lookup on the IP connecting and if it can’t find a record it causes a long delay when logging in.
If you want you can disable sshd from doing a reverse lookup by setting
UseDNS no
In /etc/ssh/sshd_config and restarting sshd.
service sshd restart
Here is a small post on how to setup pflogsumm on your CentOS mail server running Postfix. It takes advantage of logrorate being called nightly by cron.
1. Install pflogsumm
# yum install postfix-pflogsumm
2. Run a test
# /usr/sbin/pflogsumm /var/log/maillog
3. Update /etc/logrotate.d/syslog. Add the following:
prerotate
pflogsumm /usr/local/psa/var/log/maillog | mail -s "Postfix Log - `date`" [email protected]
endscript
And little script to send you log hourly if you send over 100 emails per hour.
Make sure to add it to your hourly cron job.
#!/bin/sh
hour_now=$(date | awk '{print $2,"", $3, substr($4,0,2)}')
var1=$(grep "$hour_now" /usr/local/psa/var/log/maillog|pflogsumm)
if (( $(echo "$var1" | sed -n '/ delivered$/p' | tr -d '[:alpha:]') > 100 ));
then
echo $var1 | mail -s "Postfix Log - `date`" [email protected]
fi
after update if your outlook do not work on smtp port 587 make sure to change /etc/postfix/master.cf
from:
submission inet n – n – – smtpd -o smtpd_enforce_tls=yes -o smtpd_tls_security_level=encrypt …..
to:
submission inet n – n – – smtpd -o smtpd_enforce_tls=no -o smtpd_tls_security_level=may …..
