@licson rhel有幾好用?

同centos一樣咁好用

yum my

rhel 會 unlock 啲得 RHEL 先有嘅畀錢 rpeo

有啲咩先

緊係 RH 自己啲野

本身 CentOS 個 repo 無 ffmpeg 架嘛

RH 個 repo 本身就有

supported/optimized packages

by support, it means commercial support

so theortically you can pirate rhel too

咁不如aur

easily broken

RHEL 嘅好處就係如果你用官方 repo 裝到炒咗你可以搵 RH 炒返啱

😂

同埋啲 software 雖然舊但係落足 patch

你望下 CentOS 7 都仲係用緊 OpenSSL 1.0.1e

但係已經 patch 哂最近啲漏洞

唔係一件容易嘅事嘅咁又

新version有breaking changes

yes

crazy and worth the money

不過我最憎 Red Hat Access Portal

裏面好多神奇問題嘅解決方案

但係絕大部分都要你買 subscription 先睇得個餡

https://github.com/jwasham/coding-interview-university
this is goooooooooood

終於搵到好多盲點

what do you mean

望得多真係覺得啲大陸人難服侍

🤔🤔

🤤

佢話乜野 server 都可以變做水冷

佢幫你做個 heatsink

What is asdf

I don't know

That i4hk upstream is also mysterious

APNIC now is hard to request IP

May go to RIPE

I told you already

when ?

How many IP address you requested

I see.

Is it only Twnic / Jpnic is easy

And now I finally got it

Too many Chinese in APNIC nowadays, so the policy is very strict

Nah

In fact, APNIC is a team of Asian people, their mindset is very close. Not same as RIPE as well.

It's that APNIC already run out of free ranges

I know them everyone and met.

No.

New assignments are basically recycled

103/8 is only used 62.95%

🤔

150/8 used 50%

163/8 used 35%

171/8 used 57%

My /22 is inside 103/8

And everyone told me it's the last free range 🌚

I know, that`s final /8 assigned from IANA

haha, that doesn`t know

You can check the allocation table, APNIC still have many IP address

Final /8 doesn`t mean it`s real final

The main issue is, Asian people most living in the closed mindset location

Like Japanese rised , all 103 are not allowed the transfer within 5 years

That`s crazy, only in APAC appiled this policy

RIPE is relatively free

Lots of IP brokers resell RIPE spaces

So, I will start to join RIPE to balance the rise

Very few resell APNIC addresses

APNIC is crazy nowadays

ARIN is strict too

Europen guys is more open mindset

How come not allowed to transfer within5 years, this is a crazy policy but on one come out the reject

In fact I`m the member of RIPE already.

Just not yet to request IP address.

AfirNIC

Have lots of free spaces but need African company

I will go for RIPE regional first.

Because EU law is more stable then others.

You know APAC regional only AU, Japan, HK, Singapore is developed. Other countries are un-developed. People are closed mind-set.

So I would suggest you go beyond Asia, direct to US / EU to do business.

China is a developed Country

really ? developed ?

@licson where r u

developed in politics

HK is the only a few locations that is developed

Other Asian are living in poor country

So Asia is poor

A 100 years ago, the European say here is Far East

That’s mean very far away

Somebody still say Asia is Far East nowadays

ipv6係未無分private, public?

Yes

Same as IPv4

Yes係指有定無

有

Public private local link

3 type

但點解ipv6唔洗經nat

因為 IP address 夠多

多到全世界每一粒沙都可以有 IP

咁分private public有咩意思

你想唔想你個網日日俾人nmap

v6 可以 ACL

ipv6 is da best~~~~

可以做小好多野 😂

你試下而家開個service出黎
ipv6 only 但要個個都用到
睇下係咪做少好多野

好可惜香港ipv6未普及

都係要靠hurricane啲tunnel

拉條 DIA

可以叫佢開埋 v6

話說呢邊有無人熟 PPPoE

我問下hkbn有無囉😂

有無commerical 10G broadband 我估應該無可能

有

Why not

無

but expensive as hell

How much you pay for

但係 business 嘅話就應該 唔係 GPON last mile

就算有 都唔會有consumer level 10g router😂

撥號嗰陣直接同我講 LCP terminated by peer

賬戶密碼都啱

longest common prefix/

唔係，係 PPP 嘅 Link Control Protocol

PPP 嗰陣設計其實有啲 modular

冇嘢啦 搞掂咗

40gbe thunderbolt應該唔夠

但係pcie又太多...

今日份tutorial有提到

因為佢仲行緊ipv4
當全世界用晒ipv6咁就爽
學小好多垃圾outdated bullshit

ipv6都講左好多年
而家仲有isp都唔肯用

唔做唔錯

香港啲嘢咁保守

pccw唔係有v6?

唔係

v6 過左咁耐都淨係佔 v4 流量嘅 2-3%

Nobody cares to have IPv6 set up

雖然我係有 v6

點解唔轉哂

因為美國有足夠ip

我唔洗讀咁多

唔做唔錯

v6 佔我流量 1% 都冇

所以唔想推ipv6

v4 就係 99%

其實ipv6應該要有再簡化嘅form

混合咗hex 真係好難睇

我好同意用ipv6做uuid😂

其實 link local 已經係咁玩

攞自己個 MAC Address 黎 gen 個 Link Local

SLAAC 都係

攞個 Link Local 發 ICMPv6 RA

其實有咗ipv6 p2p真係trivial implementation

係呀

ice are no more

@Slowman529 你部 1921 玩成點

個 NAT 用唔用到

同埋部 3560G

今日唔得閒 有其他task要跟左先

要唔要介紹你買部返屋企

其實你淨係買部 3560G 返屋企都已經夠玩

可以做 NAT 同埋 DHCP

公司有 又點解要買

係屋企用

唔通你可以攞埋返屋企

都可以借野

3560做到L3 Routing

咩

可以阿

都要係ISP dhcp拎ip

我都有部 3560G 啊

原來我office係有gpon

係呀

望到fiber位

咁不如搬部3560走算

公司用緊一堆2950

唔怪得咁鳩俊

3560 定 3560G

g

好大分別下

有咩分別

有 G 先係全部 Gigabit

with g spot

唔係你會淨係得 24 個 100M 頭

私伙野係3560g

有 E 嘅話就會四個 SFP 變兩個 X2

X2 係 10Gbps 界面

好在唔係垃圾fastethernet

但我部野reset唔到 試過撳實mode唔得

但我無serial port睇log

Management port

插完要比 IP 🙈

同埋 3560G 好似冇

Internal IP la

要 3750 先有

好似可以自set🤔

就係default唔到

唔知係lockout左 要靠tty

但我無線

1921就set返好喇

但係隻1921可以玩乜? site to site vpn?

可以 L2TP/IPSec

firewall?

GRE

做server?

BGP

OSPF / IS-IS / EIGRP

IP SLA

Dynamic static route

NAT 啊 ACL 啊嗰啲

不過 1921 收唔到 full table

會爆炸

哦，咁你執terminal server

無線呀屌...

你不如internal mail黎mkk

叫你買

普通cat 5🤔

收bgp收到爆ram?

係呀

tty喎

張 RSP720 收完 Full table 已經用得七七八八

console port可以行ip咩

唔係tty over cat5?

佢用 RJ45 但係 pin layout 唔一樣

駁落Digi 32,佢轉返ip出衍黎

咪就係囉

我無機有db9 male

不如直接買條線最快

買 console 轉 USB

又要蛇皇落黃金

啲driver好膠

唔會

driverless

linux內置

我個條一插即用

我隻1921 即插即用

我插落 Macbook 用 macOS

如果cisco出desktop os

我部公司win🤔

屌返到樓下好畚

凍

咁我公司都係

係帶私家機啫

咁你落去MKK m囉

我本身就mk

不過唔熟E同事

我mgr E出身

買部digi32有你so

唔洗記pin assign

拎條straight,佢自己認

公司d cam好多校園照

唔知會發生乜嘢事

最近既 Cisco IOS XE 係 based on Linux

但係個 Kernel 多左堆 Cisco specific driver 去控制堆 ASIC

100M？

係

PCCW係咪死左條

台灣邊個 ISP

冇 Traceroute 即係講空氣

返屋企再traceroute

Hinet ?

So Strange

Hinet 係唔同的

Japanese ask me to add her Wechat

直接 SDH 拉嚟香港駁 PCCW

Yes ar

仲要 Prepend 得好犀利

PCCW 要人手 Override 先可以直連到

Any Hinet IP ?

Wait

I can make a tracertroute

from PCCW

冇add錯你入嚟呢

同埋呢排隻Firewall虧虧地

係啦係啦

Cisco Firewall ?

Juniper SRX240 好似係

Waiting your Hinet IP

自申：廢柴，咩都唔識

買咗幾耐？

過曬保養㗎啦

應該就換得

上幾手留低

All are copper...............

出緊PO換

Yes ar

Replace by Cisco 10G router la.

PCCW is our permium route for China and Taiwan.

Higher price then our standard route, but cheaper then all HK providers

Home Broadband Netvigator:

Direct PCCW is less Hops between HiNet.

呢個有優化左

行左比 Hinet prepend AS Path 3x 嘅 route

點睇優化左

要睇 PCCW 個 BGP looking glass

Hinet 有幾條駁 PCCW，直接駁 PCCW Global 會行最塞個條 path

咁 Direct PCCW 又有無優化 ?

其他 Path，比 Hinet 做左 Traffic Engineerimg

變成 Backup path，得 Netvigator 有落 Override 行埋個堆路

你Post下WTT 點去 HiNet ?

via kbtelecom

What is kbtelecom

台灣中嘉和網

等我一陣

@licson 點解Virtuozzo可以support windows嘅🤔

係咪有啲魔鬼細節 例如vt-x

Tencent ????

So strange

On9Hosting is you ? Or Agent CC ?

應該係佢有 route leak

唔好搞亂

Is it PBR to tencent router ?

我同佢嗰個只係差個名少少

LOL

yes

其實點解要改啲咁奇怪嘅名...

Oh, you have next hop to tencent router.

on9host

on9host

整返

唔係我改

So strange.

How about to use Taiwan Mobile ?

其實咁樣低延遲啲

如果中嘉去香港冇乜野既話可以做到 < 20ms

on9hosting係cc既 做Web hosting
on9host係licson既 做VPS dedicate

🤔

正

暫時唔敢再reboot隻firewall

佢 又 死 左 啦

HK`

Web Login會好奇怪
然後一reboot就會炒OS

巧遠

駁緊係 cross-connect HK1

This is juicessh?

去台灣ping 去30-40 ms sad

I think that's quite obvious

公司有兩隻，好用嗎

名校都係用佢

me too

點解cisco唔開以有web UI

講緊我隻1921

聽日返去睇下iOS manual先

其實有，第二條 Line

叫 Meraki

aux?

呢個系列全部可以用精美 Web UI set 晒啲野

1921呢

冇

同埋個aux port有乜鳩用

Meraki 係俾啲懶人用

插電話線

用黎phone call>?

gonna wach ths

我地學校個隻大柴

PCCW條商業網上爬擺左隻SRX300

換

換啊

你知學校要買嘢就有一大輪程序㗎啦

依家就等緊財務部

Hi又係你呀？

係啊係我啊

世界真係細

換左佢啦

應該換fortinet

識架？

真係好

格里地鐵台嘅人

係公開撈上嚟嘅人，咁都喺度見到

火車台

仲要係未到站

Who is using RTBH

nice

我地其他campus都用緊fortinet
