Can I install netflow monitoring on a 64bit system?

Yes, but Caligare Flow Inspector is not available in 64bits binary format. You may install 64bits system and run 32bits nfcd daemon. Use the following steps to install netflow monitoring in a 64bits environment:

Install 64bits system (i.e. Debian or Ubuntu distributions).
Install ia32 backward compatibility packages. The following example is for the Debian distribution, but in the other distribution you can find similar package names...
```
apt-get install ia32-libs
```
Upload 32bits libmysqlclient to the backward compatibility directory. For the Debian it is /emul/ia32-linux/usr/lib/. You can download 32bit mysqlclient library from our web pages (libmysqlclient.so.15.0.0). Or you can use the wget tool i.e.:
```
wget "http://support.caligare.com/kb_data/libmysqlclient.so.15.0.0" -O /emul/ia32-linux/usr/lib/libmysqlclient.so.15.0.0
```

Make symlink from your 32bits mysqlclient to the version 10 (that is used by nfcd):

ln -s /emul/ia32-linux/usr/lib/libmysqlclient.so.15.0.0 /emul/ia32-linux/usr/lib/libmysqlclient.so.10

Install netflow package with force architecture flag. Example:
```
dpkg -i --force-architecture netflow-4.0.0.i386.deb
```

Make mysql.sock symlink:

ln -s /var/run/mysqld/mysqld.sock /var/lib/mysql/mysql.sock

That's all. You can run the nfcd binary via: /etc/init.d/nfcd start
