The command which you are entering is just for blocking incoming ICMP connection if you want to block outgoing ICMP connection you have to choose output chain i.e sudo iptables -A OUTPUT -p icmp -j DROP

The section you should ignore is the Configure Network Address Translation section. In fact if you want to guarantee that wireless clients can't go onto the Ethernet connection do the following: Run sudo nano /etc/sysctl.conf. Scroll to the bottom and add net.ipv4.ip_forward=0 on a new line. Save the file. This will disable ip forwarding on boot up. Run: ...

tcpdump shows you what the interface sees. Obviously packets have to arrive at the interface first before Netfilter (iptables) can kill them. Thus iptables can never prevent you from seeing incoming traffic. It can just prevent this traffic from having an effect (besides wasting your bandwidth...). But there should not be any outgoing packets any more. ...

lsof -p 1028 filters for process ID 1028. You should try: # lsof -Pnl +M -i4 for a list of open IPv4 ports and their owning processes. The -Pnl is optional, but makes it slightly quicker as it doesn't do name lookups etc for you. Or: # lsof -i :1028 to list everything listening on port 1028. If there is something strange going on, then you need to ...

Indeed, there are keyservers that listen on port 80. One such keyserver is hkp://keyserver.ubuntu.com:80. Indeed, pacman-key uses gpg under the hood. You might have tried specifying a keyserver by passing the --keyserver argument to pacman-key. This didn't work for me. You might have tried specifying a keyserver by creating or altering ...

If there is no logging specified in the firewall rule that rejects the connection attempts, then nothing will appear in the log. I suggest you read the RedHat firewalld reference which discusses adding logging requirements to firewall rules. Unfortunately, it's fairly complex and there are no shortcuts that I know of.

For a generic router, try the following as a script iptables -A FORWARD -i eth1 -d 10.10.2.0/24 -j ACCEPT iptables -A FORWARD -i eth2 -d 10.10.1.0/24 -j ACCEPT echo "1" > /proc/sys/net/ipv4/ip_forward

Based on those 1st 3 messages it would look like you need to upgrade your version of Perl to at least 5.12.3. Perl version 5.012003 (5.12.3) is at least recommended to run ASSP 2.4.3 (14313) - you are running Perl version 5.010001 - please upgrade Perl Perl version 5.012000 (5.12.0) is at least required to use the unicode Bayesian/HMM engine of ASSP ...

The problem is with the static build, as @slm mentioned. I've compiled ffmpeg from source and things work fine now.

The (commandline) utility you should be using is journalctl. E.g. to look at the the dmesg output: journalctl --dmesg or parseable entries relating to the firewall: journalctl --output=json-pretty UNIT=firewalld.service For a list of selectable UNIT use the usual tools: journalctl --output=json-pretty | grep -F UNIT | sort -u See man journalctl on ...

If you don't have a static IP address, you shouldn't be sending email directly to the Internet. Kudo's to your ISP for blocking the spambots on their network from reaching me. Even if you were allowed to send email, many hosts would refuse your mail or route it to the spam box. Configure you mail server to send via your ISP's relay server. Many ...

If your ISP is blocking outbound port 25, you've probably made a bad choice in the location of your mailserver. Because port 25 is blocked, I am assuming you have a machine inside your home/office, vs using a server. I would highly recommend that you take what you've learned from setting up postfix and install it on a cheap VPS. It is not a good idea to ...

Distros like nanoBSD, bowlfish and others use memory file systems for things like /etc, var, /tmp and others so they do not write to the flash storage. Obviousy /tmp an be safely lost without preventing reboot to a working system, and for the others the OS variant manages writing what's in the MFS mounts to the persistent storage. Bowlfish does this through ...
