平野啊…… TMHK 攞，不過都要 700 美金一櫃，電比唔係好多
我個 company registration 係第二個名
其實outbound 用 static route 去HKIX , 實際bandwidth 有幾高
嗰邊我打算搞到佢同 WTT 一齊行 Load Balance
Inbound 我有 AS path prepend
如果a send野去192.168.1.100
set左default gw
192.168.5.1a會射去192.168.5.1 (R5)
router會自己forward比b?
將個 path length 較到每個 upstream 差唔多
總之set岩d default gw, r5個兩個ip就得?
搵緊好既 local loop provider
煤氣通應 email 好慢
你PM 我location, 我check 下coverage
上次佢打機又見到條友叫AgentCC又問係唔係我，我都唔打機的。咁多人鍾意用我個名😓
幾時有intel 905p back storage
And P4800X too damn expensive
Servers w/ NVMe backplane are damn expensive
And KVM VirtIO can't take full advantage yet of NVMe
The best way still involve two layers of Directed IO
其實我最近望到部 HP Gen9 有 NVMe Backplane
HPE ProLiant DL360 Gen9
但係 垃圾 HP 唔想買
is this correct if i want to let pc to connect to internet
assume i am not using any switch
for most basic testing
R1 configure a default route the. It’s fine
Outbound router is it under your control ?
又諗返起我有個 friend 竟然買粒 Gold 6158 黎開 VPS
Don’t push one server too hard
好似又係 自己玩到咁上下就會想考埋
但你係出去上堂家自修
I see can be a VPS server
我地比人打斷咗 Internet connectivity
話時話後尾 PCCW 比左免費海纜 connectivity 佢地
去非洲我以為會揀 Ethiopia Airlines
之前都會去california google summit
但係要 join netacad 個 course 先有得官方 download
你插得卡嘅 Synology 應該就已經有 driver
屌，聽日都係返去試左最基本既NAT先，然後試埋switch
switch好似要config VLAN比D頭佢先識packet switching
話說講開劏VLAN 好似都係將D port分做唔同group
port 1 to 5 = VLAN 1
port 6 to 10 = VLAN 2
係assign不同 VLAN 落 Interface
inter f0/1
switchport access vlan 2
interface range gi0/1-10
switchport access vlan 10
要create左vlan 入 vlan table先 work
響rom 內有一個 叫 vlan.dat 的file
copy flash:vlan.dat tftp:
copy http: flash:vlan.dat
upload 好似都得，但係要個 web server 支援 HTTP PUT
前員工想我寫 ref. letter 移民 Canada
華人無人理Cyber Security ，最叻都係加隻firewall就以為會安全
係呀，特別係網絡安全，比完錢保護左你，佢又好似睇唔到咩成效
但防到一次意外，那些CEO/CIO就唔使出黎同記者鞠躬道歉
Zero day要靠NBA Network behaviour analysis
有做Backup，但無定期測試restore,所以到出事時才發現根本restore唔到
既然show 胸部就可以cut 到cost,咁胸貴定保安貴
用Vulnerability scanner scan下，可能睇到好多default password
有無人知P記隻Juniper SRX300密碼會係咩
第時有多餘錢唔買Server玩，買個支$8888電鑽上山鑽花崗岩
話說
pccw係咪做到條fibre一上黎就轉RJ45已經有兩個vlan係鼠
一條 fibre 唔係行 GPON 就係行 BiDi
Fiber同RJ45只係傳輸媒體，VLAN係通訊協定既野bor
BiDi 係一條光纖行哂來回兩條 wavelength
i mean佢係咪一入黎已經有vlan setting
Media Converter 唔理 L2 Protocol
有隻huawei fibre modem
同埋呢隻Juniper
我地d router係dlink tplink netgear
Licson d router係cisco nexus
