You need to disable the router to send the redirects: sudo sysctl -w ipv4.conf.eth0.send_redirects = 0 You will need to edit /etc/sysctl.conf and add the following line to apply the config at boot time. ipv4.conf.eth0.send_redirects = 0 However your config is neither optimal, nor secure. You should either use a router and split the network in 2 VLANs. ...

Your subnet mask is undoubtedly 255.255.255.0, so that address is not on your network. If your subnet mask is 255.255.0.0, your machine wouldn't be sending traffic to it through your gateway.

This cannot be done using DNS directly. A domain name always resolves to a single IP address, the port isn't related to DNS records at all. However, you can set up a reverse proxy on your web server that is listening on port 443. You would set up virtual hosts server.machine.com and other.machine.com on the www.machine.com web server, which would then ...

From what i know, changing BSSID is hardware related. So, unless you provide some details regarding your router, i doubt you'll get much help. Now, considering your main goal is to protect your wlan, using WPA2 with a 63 chars passphrase will do a way better job than hiding/changing SSID/BSSID.

We had the same model (or same family) long time ago and it had similar symptoms before it completely died. Network traffic slowed down, and WiFi range dropped dramatically. When opened, I noticed some of the capacitors had noticeable 'bulges'. So I'm guessing the electronics inside yours is just coming to the end of its life.

Presumably you are using PPPoE, which explains why eth1 is connected to the modem. When the PPP session is established, pppd will invoke the various scripts in the ip.up.d as you mentioned. The ifconfig commands that you show are an entirely reasonable way to set up an IP alias. The most logical reason why multiple IP addresses are used is for when ...

I would use 'debug ip packet' and trace the ICMP packets at the time you send the bursts. That would give you an idea of what was happening. More info here: Cisco Debugging And, I'll reprint the warnings from that site here: Enabling debugging can disrupt operation of the router when internetworks are experiencing high load conditions. Hence, if logging ...

you can't block https unless you decrypt the traffic somehow. The whole packet is encrypted so the router has no idea what the host header it. It only see's the destination IP and a bunch of encrypted traffic.

To answer your initial question, you'll pretty much have to restart. I couldn't find any commands available under the reduced privilege level that would let you either revert to the old config or change the password without restarting. To fix the problem you were originally trying to solve, if you're not using aaa-newmodel, what you can do is set a user ...
