Those commands are not for debian.
cd $INSTALLDIR ; rm -rf avg75flr-$AVG.i386.rpm
wget http://www.grisoft.cz/filedir/inst/avg75flr-$AVG.i386.rpm
yum -y install pygtk2* ; rpm -i avg75flr-$AVG.i386.rpm ; /opt/grisoft/avggui/bin/avggui_update_licinfo.sh
avgupdate --online /opt/grisoft/avg7/data ; /etc/init.d/avgd stop ; /etc/init.d/avgd start ; avgscan -d
echo ; echo "Install/Update AVG Anti-Virus Free Edition $AVG2 for Linux done"
Yum errors; because debian uses aptget and no yum
RPM errors; sure you have the rpm package loader? in my past live i used special .deb packages for debian and no plain rpm's.. if im correct.. centos minded here..
The rest of the errors are just followups from the first..
Nope the script is fine, just not suitable for your debian installation, in this case..
Since the ip_tables, xt_state, and/or xt_multiport modules do not exist, KISS can not function. Firewall script aborted!
ln -s /lib/modules/2.6.9-78.0.1.ELsmp/kernel/net/netfilter/xt_state.ko /lib/modules/2.6.9-78.0.1.ELsmp/kernel/net/ipv4/netfilter/ipt_state.ko
and
ln -s /lib/modules/2.6.9-78.0.1.ELsmp/kernel/net/netfilter/xt_multiport.ko /lib/modules/2.6.9-78.0.1.ELsmp/kernel/net/ipv4/netfilter/ipt_multiport.ko
ln: `/lib/modules/2.6.9-78.0.1.ELsmp/kernel/net/ipv4/netfilter/ipt_state.ko': File exists
sintsu...
I may be wrong here but if you are using dovecot, then you dont need / should not use IMAP-2004, as both are imap systems...
