DNS ubuntu18 'resolv.conf vs systemd-resolve --status'

Dah set di netplan utk guna more than  1 DNS, (boleh verify guna systemd-resolve --status)
Tapi di /etc/resolv.conf masih guna 127.0.0.53

Penyelesaian:

cd /etc
sudo ln -sf ../run/systemd/resolve/resolv.conf /etc/resolv.conf

services dan svchost dalam windows

1- services adalah senarai services

2- svchost adalah process yg akan hostkan service. Ini berlaku jika service tersebut hanya ada dll file. (Bagi services yg ada exe file, tak perlukan svchost)


Contoh 1(Servis guna exe file)-----------------------

HKLM\SYSTEM\CurrentControlSet\Services\
-- ImagePath -> c:\dir\contoh.exe


Contoh 2 (Servis guna dll file)---------------------

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Svchost
-- NetworkService: DNSCache lanmanworkstation DHCP

(Dnscache)
HKLM\SYSTEM\CurrentControlSet\Services\Dnscache
-- ImagePath : %SystemRoot%\system32\svchost.exe -k NetworkService -p

HKLM\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters
-- ServiceDll : %SystemRoot%\system32\dnsrslvr.dll

(LanmanWorkstation)
HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation
-- ImagePath : %SystemRoot%\system32\svchost.exe -k NetworkService -p

HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters
-- ServiceDll : %SystemRoot%\system32\wkssvc.dll

Mengenali disk image via mmls fsstat fls losetup

image: disk1.dd


1- mmls utk listkan partition dlm disk
2- dapatkan offset partition yg berkenaan
3- fsstat -o xxx akan listkan maklumat file system pada offset xxx
4- fls perlu guna -o xxx utk create body file partition tersebut.

5- loosetup boleh create /dev/loopX utk mudahkan akses partition tersebut. Namun perlukan maklumat offset dalam unit byte. (mmls papar maklumat berdasarkan sektor)
 Maka :  xxx * 512(byte persektor) utk dptkan offset.



1-

# mmls -t dos disk1.dd
DOS Partition Table
Offset Sector: 0
Units are in 512-byte sectors

 Slot    Start        End          Length       Description
00:  Meta    0000000000   0000000000   0000000001   Primary Table (#0)
01:  -----   0000000000   0000002047   0000002048   Unallocated
02:  00:00   0000002048   0000499711   0000497664   Linux (0x83)
03:  00:01   0000499712   0041940991   0041441280   Linux (0x83)
04:  -----   0041940992   0041943039   0000002048   Unallocated

# fsstat -o 2048 disk1.dd

4-  fls -o 2048 -r -m C: disk1.dd > fls-bodyfile.txt

      Then you can create timeline:
      mactime -z UTC -y -d -b fls-bodyfile.txt 1500-01-01..2020-01-01 > mactimeline.csv

5- 

# expr 499712 \* 512
255852544
# losetup -f
/dev/loop0
# losetup -r -o 255852544 /dev/loop0 disk1.dd

Masalah mount windows share folder

semak senarai share folder windows dari linux

smbclient -L  -U  -d 256

ubuntu 16 default guna protokol smb 1

Manakala window tak support smb1, sebaliknya smb2.1 dan 3.

Maka tambah -m utk specify protokol

smbclient -L  -U  -d 256 -m smb2

Utk mount tambah vers=3 pada parameter -o

sudo mount -o vers=3.0,username=,uid=,gid=,forceuid,forcegid, //IP_Address/share_name /mnt/path/

Domain(Active Directory) user:

smbclient -L  -U _user_  -W _domain_name_ -d 256 -m smb2

sudo mount -o vers=3.0,username=_user_,domain=_domain_ //IP_Address/share_name /mnt/path/

Interactively:

smbclient //10.108.242.242/FSC -U _user_ -W _domain_
