ssh hangs – very slow ssh on mac

Robin — Sun, 05 Jun 2011 06:14:05 +0000

Since a few days ssh was very slow, searching many hours brings me to my router and suddenly i saw the problem…
Telenet my Internet Providers nameservers are slowing down the whole thing…

after verbose i had (ssh -vvv):
debug2: channel 0: open confirm rwindow 0 rmax 32768
and then it hangs/freeze

So from now i use http://www.opendns.org and everything is working again!

Plesk missing db user

if the mysql user of a site isn’t listed in the plesk interface, do the following:
1. log into mysql as admin (eg. using cmd line)
2. delete the entry of that user in the mysql user table(eg. DELETE FROM user WHERE user=’username‘;)
3. add the user via plesk.

Procmail and Plesk

I’m using more computersystems for mail but my macbook is not always online, so i find a way to make message rules and sort mail in maps before checking it in a mailclient!

How it works? Simple you need serveraccess for this, procmail and some adjustments in .qmail file!

First of all as a .procmailrc file i had the following:
MAILDIR=/var/qmail/mailnames/yourdomain.com/mailname/Maildir DEFAULT=${MAILDIR}/ SPAMDIR=${MAILDIR}/.Junk/ :0 * ^X-Spam-Status: Yes.* ${SPAMDIR} :0 * ^Subject:.*The Plesk Scheduler notification ${MAILDIR}/.AAA\ Plesk\ Admin/

This code does two things, first put mail marked as spam in the Junk folder and as second it put mails with a subject in an other dir!

Offcourse don’t forget to change your .qmail file:
| true | /usr/bin/procmail -m -o ./.procmailrc

From now your mail will be sorted before it is checked in any client! Usefull if you also use a smartphone

Install postfix mailserver only for forwarding

Robin — Tue, 01 Jun 2010 20:49:06 +0000

For some reasons i only had to install a mailserver for forwarding mails to other mailaddresses. So on Centos here you have it:

#yum install postfix smtpd

edit /etc/postfix/main.cf

myhostname = your.domain.tld

virtual_alias_domains = redirectdomain1.tld, redirectdomain2.tld
virtual_alias_maps = hash:/etc/postfix/virtual

edit /etc/postfix/virtual

address@redirectdomain1.tld addresto@domainto.tld

@redirectdomain2.tld addresstocatchall@domaintoxx.tld

After this run the following commands:

# postalias /etc/aliases
# postmap /etc/postfix/access
# postmap /etc/postfix/virtual
# postmap /etc/postfix/transport
# cp /etc/aliases /etc/postfix/
# newaliases
# postfix reload

Now the server is ready to forward your mails!!!
