[Linux] script สำหรับ check process แบบง่ายๆๆๆๆ

สืบเนื่องมาจากเปิด transmission-daemon ไว้แล้วมัน crash บ่อยเลยอยากให้มี script ไว้ตรวจสอบแล้ว restart อัติโนมัติ

$vi psmon.sh
#!/bin/sh

pid=`ps -ef|grep transmis|grep -v grep|awk '{print $2}'`
if [ -z "$pid" ]; then
echo "Process NOT running, Start process now!"
/etc/init.d/transmission-daemon restart
date >> /home/ubuntu/Ubuntu/psmon.log
else
echo "Process running"
fi



$chmod 755 psmon.sh
แล้วเรียก script ใน crontab ทุกๆ 5 นาที
$crontab -e
*/5 * * * * /home/ubuntu/Ubuntu/psmon.sh

[Linux] ใช้ wireshark บน text mode

ผมติดการใช้งาน wireshark แต่พอดีมาใช้บน linux แล้วเป็น text mode command line ใช้ tcpdump มันแสดงผลไม่สวยเห็น wireshark มีบน text เหมือนกันชื่อ tshark

install
$sudo apt-get install tshark
$sudo tshark -i eth0 -V -f "host 192.168.1.1"
ตัวอย่างมีการ capture interface eth0 โดยมี filter ที่มี src หรือ dst เป็น 192.168.1.1 แล้วแสดงผลเป็น tree คล้ายๆ GUI

[Cisco] QoS ทำการ marking ค่า DSCP แล้ว ไม่เห็นค่าที่ mark

Diagram

[SERVER]-----------[CAT1]---------------[CAT2]----------[CLIENT]

อุปกรณ์เป็น Cisco Catalyst6509 มีการ marking input packet จาก SERVER ที่ตัว CAT1 แล้วมาจับ packet ที่ client พบว่า packet ค่า dscp เป็น 0
เนื่องมาจากว่า catalyst6509 มีค่า default ในการ rewrite packet ToS->DSCP
โดยดูจาก command: show mls qos
QoS is enabled globally
QoS ip packet dscp rewrite enabled globally <---- by default
Input mode for GRE Tunnel is Pipe mode
Input mode for MPLS is Pipe mode
Vlan or Portchannel(Multi-Earl) policies supported: Yes
Egress policies supported: Yes


----- Module [5] -----
QoS global counters:
Total packets: 1795932
IP shortcut packets: 0
Packets dropped by policing: 0
IP packets with TOS changed by policing: 459413
IP packets with COS changed by policing: 57
Non-IP packets with COS changed by policing: 0
MPLS packets with EXP changed by policing: 0

จึงทำให้มีการ rewrite ค่าของ DSCP ที่เรา mark ไว้ตั้งแต่ CAT1 เป็นค่าที่ได้จากการ map ToS ค่าจึงเป็น 0 (พูดถึง default mapping จาก ToS->DSCP)
แต่ถ้าต้องการ disable ทำได้ 2 วิธีคือ
1. ตัว CAT2 ที่ global config mode
conf t
no mls qos rewrite ip dscp

!verify
sh mls qos
QoS is enabled globally
QoS ip packet dscp rewrite disabled globally <--- disable
Input mode for GRE Tunnel is Pipe mode
Input mode for MPLS is Pipe mode
Vlan or Portchannel(Multi-Earl) policies supported: Yes
Egress policies supported: Yes


----- Module [5] -----
QoS global counters:
Total packets: 3631461

IP packets with TOS changed by policing: 550481

Non-IP packets with COS changed by policing: 0
MPLS packets with EXP changed by policing: 0


2. ตัว CAT2 ที่ interface ที่ต่อกับ CAT1
interface x/x
mls qos trust dscp

[Cisco] QoS for GRE tunnel

เราต้องการ implement QOS บน tunnel interface เนื่องจาก traffic วิ่งอยู่บน tunnel

pre-config บน physical และ tunnel ปกติครับ

ip access-list extended data
permit ip any host 2.2.2.22
ip access-list extended voice
permit ip any host 2.2.2.2
!
ip route 0.0.0.0 0.0.0.0 Tunnel0


policy-map QOS
class voice
priority 128
class data
bandwidth 1024

int tu0
service-policy output QOS <== เมื่อเราป้อน service-policy บน interface tunnel จะเห็น warnning ว่าไม่สามารถ support
Class Based Weighted Fair Queueing not supported on interface Tunnel0



ปกติถ้ามีการ implement QOS บน physical interface เราจะไม่สามารถ classify packet ได้เพราะมันถูก encasulation ด้วย tunnel ไปแล้ว
แต่ถ้าไป implement บน tunnel ก็จะติดfeature บางอย่างบน tunnel interface


วิธีแก้ดังนี้


Solution:
Reference: h**p://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a008017405e.shtml



class-map match-all data

class-map match-all map-voice
match ip precedence 2
class-map match-all map-data

class-map match-all voice

!
!
policy-map QOS
class map-voice
priority 128
class map-data
bandwidth 1024
policy-map QOS-tunnel
class voice
set ip precedence 2
class data
set ip precedence 6

int tu0
qos pre-classify
service-policy output QOS-tunnel
int s1/0

Tunning TCP window size ของ Windows

ผมลอง FTP ระหว่าง linux กับ XP ไป Siteเดียวกัน Link เดียวกัน ปรากฏว่าผล download ของ Linux ดีกว่า เลยต้องปวดหัว ดูจาก packet ก็น่าจะเกี่ยวกับ window size เลยไปถามพี่ google พี่แกก็เลยบอกมาว่าไปดูที่ h**p://rdweb.cns.vt.edu/public/notes/win2k-tcpip.htm ซึ่งหลังจาก tunning registry แล้วก็ Ok เลย

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]


The names/values I installed are:
