Re: NetMon
Can't help you with netmon since most of the troubleshooting tools I used are windows based like (ethereal, wireshark), but I found/find TCP/IP Illustrated, Volume 1: The Protocols by W. Richard Stevens to be invaluable.
You are also likely to be using Cisco infrastructure, so learn about the various debug and show commands.--- begin sig file ---

There is a fifth dimension, beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of man's fears and the summit of his knowledge. This is the dimension of imagination. It is an area which we call the Twilight Zone.

Re: NetMon
what distro will you be using?
some basic concepts:
root- the most powerful user on the system, hence the alternate term "superuser". one "goes root" in the command line by either putting "sudo" before the command (debian based), or typing "sudo -i" (debian based) or "su -" (red-hat based, possibly others). sudo+command will give you superuser privliages for 10 min before having to re-type the password and has some limits on what you can do. the second option puts you in as full root, and you are root for an indefinente length of time.
module- kinda like drivers in windows, they are normallt loaded on boot or when somehting hot-pluggable is connected. more below.
a few basic commands that are mostly distro- independant: (*= must be root)
ls ^ - shows what files are in in directoty ^ (example: /etc/samba)
lsmod- show what modules are loaded at the present time
*modprobe ^ - load module ^
lspci- shows all devices connectged by pci (includes ISA, AGP, PCI-e, cardbus, expresscard). no modules required- this is good for ruling out massive hardware problems and finding drivers for unknown hardware. (why even windows repair guys have a live linux disc handy)
lsusb- shows all usb devices. again, handy for troubleshooting and driver finding.
*reboot- the command line way or restarting a computer.
until i have a distro, i cannot say much more...sigpic

Dear all,
I forgot my BIOS password of my Surface Pro 3, I searched for solutions for a long time and knew that by using FPT to dump my bios to bin file and using decryptor, I can get my BIOS password.
Now I have a problem that I am unable to dump my BIOS into bin file.
My Surface Pro 3 currently runs on Ubuntu 22.04, with Secure Boot enabled and Boot From SSD Only.
I searched for FPT but there is no Linux version and none of them work.
I hereby request a copy of Intel Flash Programming Tool for Linux x64.
I would really appreciate it if anyone... -
Hello!
Unfortunately my Lenovo L14 Gen 1 (motherboard NM-C741) was involved in a terrible mishap. At first, one of my friends accidentally spilled coffee on it which made some of the ports stop working but the computer worked fine otherwise. After that I stupidly opended it and forgot to disconnect the battery... One thing leads to another and I accidentally short it between two components (unfortunately I do not remember which components). After that I get nothing, no charging indication, no boot indication, no fan spin, nothing.
So I'd love to learn my mistakes and... -
Hello guys!
