vnstat: Monitor Network Traffic

vnstat monitors network traffic in linux with a command line interface. It's very useful for keeping traffic database of your traffic as well as real time traffic numbers. It creates a database for the default interaface - enp2s0.

You can check your exact interface names with ip addr. 
[donato@archdesktop ~]$ ip addr  1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000      link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00      inet 127.0.0.1/8 scope host lo         valid_lft forever preferred_lft forever      inet6 ::1/128 scope host          valid_lft forever preferred_lft forever  2: enp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000      link/ether 78:24:af:36:61:21 brd ff:ff:ff:ff:ff:ff  3: wlp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000      link/ether 28:f3:66:20:7a:1e brd ff:ff:ff:ff:ff:ff      inet 192.168.15.3/24 brd 192.168.15.255 scope global dynamic noprefixroute wlp4s0         valid_lft 80684sec preferred_lft 80684sec      inet6 fe80::7a2b:48f9:dc0e:e147/64 scope link noprefixroute          valid_lft forever preferred_lft forever      inet6 fe80::f3bf:83d9:f401:2056/64 scope link noprefixroute          valid_lft forever preferred_lft forever  4: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 100      link/none       inet 10.135.15.41/24 brd 10.135.15.255 scope global noprefixroute tun0         valid_lft forever preferred_lft forever      inet6 fe80::3d1:eff7:1c52:5f44/64 scope link stable-privacy          valid_lft forever preferred_lft forever  

Then start by creating a database for the interface. 
$ sudo vnstat --add -i [interface]

I check my traffic with the command:
$ vnstat -h [hourly]
$ vnstat -d [daily]
$ vnstat -l [real-time]

Password Issues On Ubuntu Login

I found myself unable to enter my login credentials when prompted to do so in Ubuntu. I think I might have changed it then forget about it. I've been running the current session for more days than I should have. I forget. So what's the solution to my problem. How do I get in to my system now? It involved getting into the grub menu somehow. I am uncertain as to how to do that exactly in your system. So there's a couple of ways to do it (finger's crossed). When booting at system start, use the esc key or the shift key. The first one worked for me. The timing is key. Wait until the bios banner shows then hit the esc key once. I am using Ubuntu 22.04.4 here. I have a current version of grub. The grub menu will give you options and the one you want is: root. Yes you want root privileges to set the root password. It should give you a terminal access where you can issue commands. Type: #mount -rw -o -s remount / ==> this command mounts the filesyste...

2024 So Far

I have a feeling of moving earth or walking off my itchiness. The growing fat in my belly tells me I am failing on many occasions to give in to this urge. My eyes are blurred by morning glory. I remember my father having the same ritual in the morning. After his weak stroke, he couldn't speak much, just a grunt but he would demonstrate with hand how he liked to wash his face. The weather wasn't helping. It's been raining cats and dogs the past week. The province of Rizal was soaked and spilled volumes of water into the bay and Laguna lake. Our Caimito tree was cut to no more than 4 feet from the ground. It was towering above the corrugated sheet metal of our roof. Now it lay horizontal on the yard. I calculated it could be made into a whole table and chairs set by a talented carpenter artist. I showed Lino the two big pieces of trunk that could only be moved if cut by a power saw in place. The road widening project in San Mateo was in the middle stage. One side of the road ...
