Question regarding Linux based firewalls

Asked By gaffyjen 30 points N/A Posted on - 07/28/2011

Hello,

With reference to https://dovecot.org/list/dovecot/2011-January/056508.html

It is stated that "A Linux based firewall can lose entire file systems and keep running". Does every Linux-based firewall package automatically inherit this fault-tolerance or does this only apply to some firewalls?

Please help me out as soon as possible. I await your response.

Best Regards,

Gaffy Jen

Question regarding Linux based firewalls

While reading the article, one can easily observe I/O errors being displayed as read/write. The article also talks about cells that should be read-only when the write-cycles permanently run out. This would result in a failure that is not so severe. If the SSD does fail while it is in read-only setting, it does not technically mean it will fail. Also, while Linux is initiated, one will not see any type of disk I/O which would relate to the filtering process. Therefore, one can run the program with no particular disk. If logging fails, it would be mainly be due to the folder system.
