KVM thì bạn tham khảo Promox, nó có file iso cài xong là xài qua web interface thôi.
Còn cài CentOS -> KVM thì có thể quản lý VPS qua Ubuntu desktop.

Nhưng cái này bị hạn chế là khi bạn chạy backup các VPS sẽ bị suspend.

Xen Citrix & VMWare vSphere cũng là giải pháp hay smilie

Dòng đó em cũng thấy lạ. Có thể là log từ Zimbra, vì khi kết thúc ssh từ LinuxMint nó vẫn có

tamkt@tamkt-nn ~ $ date
Thu Jan 24 13:50:03 ICT 2013
tamkt@tamkt-nn ~ $ ssh -l root mail.domain.local
Read from socket failed: Connection timed out
tamkt@tamkt-nn ~ $ date
Thu Jan 24 14:19:59 ICT 2013
tamkt@tamkt-nn ~ $

Log vẫn thấy dòng đó

LinuxMint là máy thật, XP & Ubuntu là máy ảo trên VirtualBox.

Em up tiếp 2 đoạn log

Những đoạn em bỏ toàn là của Zimbra thôi ah

Em update lại tí.
Em install thêm 1 máy ảo Ubuntu 11.10, vẫn từ mạng 2 mạng trên thì ssh okie

@virusflu: Bác cài Zimbra đang bị lẫn lộn rồi. Nếu mà server qua NAT thì bác dùng dns local thôi, khi đó MX, A về IP local thôi.

IP .179 là máy LinuxMint, IP .160 là máy ảo XP

Do tuần vừa rồi em phải lon ton đi tìm nhà smilie

nên giờ mới test lại được

Đây là ảnh capture từ Wireshark

- Cho mình xem output khi chạy `ssh -vv -c 3des-cbc -m hmac-sha1,hmac-ripemd160 root@mail.domain.local` với version 5.5p1 nhé http://ftp.jaist.ac.jp/pub/OpenBSD/OpenSSH/portable/openssh-5.5p1.tar.gz).
- Trên server, tạm thời chỉnh LogLevel sang DEBUG2 rồi cho mình xem đoạn log tương ứng nhé. (xong nhớ chỉnh lại thành INFO không nó lặi "ăn" hết ổ cứng)
- Mà bạn sniff thử trong quá trình ssh đi xem Packet length là bao nhiêu.
- Quên mất, bạn thử đề nghị này của mình chưa:

- Vác mấy máy Linux không ssh được này đến một chỗ khác (mạng khác) để thử xem.

- Bạn đang dùng wifi à? Mạng chỗ bạn có đi qua con Cisco nào không?

1-2-3 em sẽ up lại sau

4. Em thử 2 mạng khác nhau vẫn bị vậy
5. Mạng ở nhà thì e dùng wifi qua 1 con TP-Link & Draytek. Mạng cty thì dây chắc là qua 1 đống cisco.

- Thử với 1 phiên bản OpenSSH trước 5.7p1 (5.5p1 chẳng hạn) xem có được không.

- Vác mấy máy Linux không ssh được này đến một chỗ khác (mạng khác) để thử xem.

Không chỉ riêng máy này không ssh được mà em thử rất nhiều máy linux từ Ubuntu, CentOS đều bị vậy.

Em up đoạn log mà anh quanta yêu cầu khi chạy lênh ssh -c aes128-ctr root@mail.domain.local

Và cuối cùng là

Google thử mấy cách trên forum cPanel mà vẫn chưa fix được.

Samba4 hình như vẫn chưa care được vụ GPO hay sao mà bác.

Mấy ngày nghỉ, rảnh rỗi ở nhà em có lab thử backup/restore Zimbra.

Làm theo hướng dẫn ở link http://blog.zimbra.com/blog/archives/2007/10/moving-zcs-to-another-server.html

Thấy mọi thứ backup/ restore đều okie. Nhưng lạ cái là không thể nào ssh vào được. Sau đó em có cài lại openssh. Add thêm 1 user nữa, restart lại server & services mấy lượt thì mới ssh vào được.

Bác nào dùng Zimbra có gặp trường hợp này không ah.

Tks.

bác nào gặp tình huống này thì remove bind-chroot là được thôi smilie

có bác nào biết ko vậy ?
mình vẫn chưa tìm ra cách smilie

Mình có 1 file named.conf

options {
allow-transfer {none;};
directory "/var/named";
};
zone "." IN {
type hint;
file "data/named.root";
};
zone "dns.domain.local" IN {
type master;
file "data/db.dns.domain.local";
};

và 1 file zone.conf ( nơi chứa các zone )

zone "domain.local" IN {
type master;
file "data/db.domain.local";
};

Mình ko biết cách nào để file named.conf nó có thể gọi đc nội dung của file zone.conf. Search thử include nhưng hình như ko phải, start named lên toàn báo zone.conf not found. Bác nào biết vụ này chỉ mình với.

Cảm ơn.

bác ko ssh đc hay ssh vào rồi ko qua root được ?
thường nó phải có output mà

sao ko gộp 2 cái server vào cho tiết kiệm nhỉ

kiếm cái cờ rack mà cài ko thì qua virtualbox vừa free vừa nhẹ lại dễ dùng smilie

modem zyxel có chức năng block keyword, mình add yahoo vào thấy cũng ko chat đc.
nhưng ko block fb khi họ vào bằng https được.

mở virtual network editor, VMnet0 chọn wireless WLAN, rồi quay lại cái hình bạn up chọn cái nào Custom -> VMnet0

thanks bác KyO

lúc post bài e ko refesh nên ko biết là có bài của bác.

sau bao nhiều lần reinstall cuối cùng nó cũng được smilie
