I'm doing a CISCO network certification in school and I get the feeling, that CISCO straight up ignored the last 30 years of OS development.

    @Root I guess their marketing calls it "enterprise".

    Why do you think so?

    Cisco still uses IOS for their devices,
    Their own OS, that they have written before the time of Linux and FreeBSD.
    Its lacks many features that are a staple in modern OSes, like preemptive multithreading, virtual address spaces, namespacing,...
    You know, shit that is actually relevant for performance and security.
    Furthermore IOS doesn't even have a fucking posix-shell, but a hacked together mess of none sensical commands (at least if you're used to proper OSes).

    @metamourge They don't actually care about security much. If you keep that in mind when looking at their product decisions (and numerous exploits), everything starts making more sense.

    Well I tried to use one if their higher end firewalls for 6 months.

    Anytime w tried to do anything beyond the most basic things, rules stopped working without explanation or logic pattern

    And since I have experience of old windows firewall, ipchains, iptables, enternet(now clavister) and fortigate I consider my knowledge above beginner bu their java based gui (requiring an obsolete java version) was completely horrible with multi level popups and almost no overview.

    Cisco is overpriced & insecure junk.

    Im late to this rant, but i really do believe this is one of the main reasons that people are going to cloud; this is all abstracted, and you don't really have to deal with this kind of hardware.

    @arcsector Someone else gets to install the Cisco stuff in the data centre instead of you. 🤣
