[유틸리티] 간단하게 상대방 동의하에 원격지원을 할 수 있는 툴



예전부터 원격지원을 하기 위한 무료원격 툴은 많았지만 이번 것은 상당히 편한 구성으로 되어있습니다.


 

만약 원격 지원을 할 때 네이트를 사용하지 않는 고객의 경우 네이트온 원격지원을 사용할 수 없으므로,

알서포트 원격지원을 사용하지 않는 회사의 경우 1:1 고객 원격지원에 애로사항이 많이 있었습니다.



 

# 실행방법 (예 : 엔지니어-원격 하려고 하는 자, 고객–원격 당하고자 하는 자)

1.     첨부의 파일을 엔지니어, 고객 둘 다 실행합니다.

TeamViewerPortable_en.exe


2.     아래와 같은 창이 엔지니어, 고객 둘 다 뜹니다.



3.     원격지원을 당하고자 하는 사람이 ID와 비밀번호를 상대방에게 알려주면,
원격지원을 하려고 하는 사람이 Create session에 ID를 입력합니다.

4.     그러면 아래와 같이 비밀번호를 물어보는데 비밀번호 입력 후 바로 원격지원을 할 수 있습니다.


 

 

# 몇 번 사용해본 결과 거의 모든 OS (윈도우 XP, 비스타, 윈도우 7)에서 잘 동작하며,

기존에 사용하던 NQVM 및 넷미팅, 네이트온 원격지원, MSN 원격지원 비교 시 상당히 편하며 빠르다는 것이 확인되었습니다.

(메일로 고객사 측 또는 상대방에게 파일을 보낸 후 유선상으로 ID와 비밀번호만 물어보면 됨)

 

엔지니어 외에 남의 PC를 원격으로 봐주시거나 반대로 프레젠테이션 기능을 통해서 원격 PPT를 하실 때에도 유용하게 사용될 수 있다고 생각됩니다.

(VPN 통신 및 파일 전송도 가능합니다.)

[ping] ping 명령어 옵션


Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
            [-r count] [-s count] [[-j host-list] | [-k host-list]]
            [-w timeout] target_name


Options:
    -t             Ping the specified host until stopped.
                   To see statistics and continue - type Control-Break;
                   To stop - type Control-C.
    -a             Resolve addresses to hostnames.
    -n count       Number of echo requests to send.
    -l size        Send buffer size.
    -f             Set Don't Fragment flag in packet.
    -i TTL         Time To Live.
    -v TOS         Type Of Service.
    -r count       Record route for count hops.
    -s count       Timestamp for count hops.
    -j host-list   Loose source route along host-list.
    -k host-list   Strict source route along host-list.
    -w timeout     Timeout in milliseconds to wait for each reply.


--
-t : 정지할 때 까지 계속 ping을 보냄, Ctrl+C 는 중지, Ctrl+Break 는 통계 표시 후 계속 보냄



-a : 호스트명이나 FQDN을 보여줌



-n : echo request를 보낼 횟수를 정함 (기본은 4번)



-l : 보낼 패킷의 크기를 정함 (기본은 32바이트, 최대값은 65500바이트)



-f : 패킷이 라우터 등을 통과할 때 fragmentation 되지 않도록 정함

-i : 패킷이 네트워크 상에서 생존할 수 있는 시간 즉, Time To Live를 지정함 (라우터를 하나 거칠때 마다 1씩 감소, 기본은 윈도우의 경우 128)

위의 경우 kns.kornet.net 의 경우 해당 PC에서 6단계를 거쳐 통신됨
그러므로 TTL을 6으로 정하면 reply가 오지만, TTL을 5 이하로 정하면 TTL이 expired 되었다고 함



-v : 패킷의 TOS를 지정할 수 있음 (IP 헤더의 DS 필드값 조정을 통해 QoS를 변경할 수 있음)



-r : 라우팅 되는 Hop count를 기록할 수 있음 (최대 9개까지 IP 헤더의 Options 부분에 저장함)



-s : r과 마찬가지로 IP 헤더의 Options 부분에 경유한 라우터의 주소와 시간을 기록함 (최대 4개까지 가능)


-j : ...

-k : ...

-w : ...

[UDP] UDP의 프로토콜 넘버는 ?


http://www.iana.org/assignments/protocol-numbers/
에 보면 IANA에서 지정한 UDP의 프로토콜 넘버는 17입니다.




테스트를 통해 맞는지 확인해 보겠습니다.

NTP 시간동기화를 할때 Wireshark를 통해 UDP 패킷을 떠보기로 했습니다.


해당 IP 207.46.232.182는 윈도우 PC에서 시간동기화를 할 때 time.windows.com으로 NTP 서버의 IP 입니다.

Wireshark로 패킷을 뜬 후 NTP 정보만 Sort 하였습니다.


중간에 보면 IP 헤더에 포함된 UDP의 프로토콜이...

11로 되어있습니다.

처음에는 Hex 값인 줄 모르고 대단한 오류를 발견한 줄 알았습니다...ㅜㅜ

0x11 이니...Decimal로는 17, UDP의 프로토콜 넘버는 17이 맞네요...OTZ

Windows Virtual PC는 가상화기능을 이용하여 윈도우 7에서도 XP를 돌릴 수 있는 기능입니다.


먼저 PC의 메인보드 및 프로세서가 가상화기능을 지원하는 지 확인해 볼 필요가 있습니다.


아래 다운 사이트에서 해당 유틸리티를 통해 가상화 지원여부의 확인이 가능합니다.

제 PC에서 확인해본 결과...


지원 가능한 걸로 나오네요...^^;

NTP 즉, Network Time Protocol은 RFC 1305에 명시된 프로토콜로 네트워크 시스템에 시간을 동기화하는 기능을 가지고 있습니다.

가장 널리 사용되는 NTP서버는 ntp.isc.org 입니다.

이번 세션에서는 내부 서버에 NTP 데몬을 돌리는 방법을 살펴봅니다.


1. 메인 NTP의 alive 여부를 살펴봅니다.
 [root@localhost ~]# ntpdate -b pool.ntp.org
 7 Dec 17:26:12 ntpdate[3015]: step time server 121.131.26.43 offset -86325.133642 sec


2. 상위 NTP로 설정할 time source를 확인합니다.
[root@localhost ~]# nslookup 0.pool.ntp.org
[root@localhost ~]# nslookup 1.pool.ntp.org
[root@localhost ~]# nslookup 2.pool.ntp.org

NTP pool의 경우 가능한한 Load Balancing되는 서버로 설정합니다.

[root@localhost ~]# nslookup 0.pool.ntp.org
Server:         168.126.63.1
Address:        168.126.63.1#53

Non-authoritative answer:
Name:   0.pool.ntp.org
Address: 115.139.9.150
Name:   0.pool.ntp.org
Address: 211.109.14.143

[root@localhost ~]# nslookup 1.pool.ntp.org
Server:         168.126.63.1
Address:        168.126.63.1#53

Non-authoritative answer:
Name:   1.pool.ntp.org
Address: 118.219.234.251
Name:   1.pool.ntp.org
Address: 211.233.40.78

[root@localhost ~]# nslookup 2.pool.ntp.org
Server:         168.126.63.1
Address:        168.126.63.1#53

Non-authoritative answer:
Name:   2.pool.ntp.org
Address: 218.50.1.115
Name:   2.pool.ntp.org
Address: 221.139.48.11



3. NTP 서버의 접근제어 및 기타 구성을 합니다.
restrict 127.0.0.1
restrict 0.pool.ntp.org mask 255.255.255.255 nomodify notrap noquery
restrict 1.pool.ntp.org mask 255.255.255.255 nomodify notrap noquery
restrict 2.pool.ntp.org mask 255.255.255.255 nomodify notrap noquery

server 127.127.1.0
fudge 127.127.1.0 stratum 10
driftfile /var/lib/ntp/drift
broadcastdelay 0.008
keys /etc/ntp/keys


- 참고 -
restrict default kod nomodify notrap nopeer noquery

restrict : Deny all packets and queries
kod : Send Kiss-Of-Death packet on access violation
nomodify : Deny ntpq / ntpdc queries that attempt to modify the server //설정변경 관련 명령을 무시
notrap : Deny control message trap service //이벤트 트랩 무시
noquery : Deny all ntpq / ntpdc queries
noserve : Deny all queries - except ntpq / ntpdc
notrust : Deny access unless cryptographically authenticated (ver 4.2 onwards)
nopeer : Deny all packets that attempt to establish a peer association //클라이언트에 시간서비스를 제공하되 peer memory를 할당하여 관리하지 않도록함

--
server : Specifies that a server is running on the host (own local clock)
fudge : Passes additional information to the clock driver
stratum 10 : Manually sets the Stratum the server should operate at (1-15)
driftfile : Specifies the location of the frequency file //시간오차의 평균값 저장
broadcastdelay : Sets the propagation delay from the server when broadcasting
keys : Store a list of keys needed for any cryptographic links

4. 서비스를 재시작 합니다.
 # service ntpd restart

# ntpq -pn으로 서버 리스트를 확인합니다.
# /var/log/messages 파일에서 ntp 관련 메시지를 확인합니다.



# 클라이언트에서 확인하는 방법
1. 윈도우 환경


2. 리눅스 환경

restrict default ignore
restrict 127.0.0.1
restrict 192.168.0.102 mask 255.255.255.255 nomodify notrap noquery
server  192.168.0.102 # local clock
driftfile /var/lib/ntp/drift

[리눅스] 윈도우에서 realvnc로 리눅스 접속하기

윈도우에서 ssh로 접속할 경우 CLI 환경에서 리눅스를 사용할 수 있지만,
vnc를 통해서 GUI 환경으로 리눅스에 접속할 수도 있습니다.

# 방법

실습은 Cent 5.3 에서 하였습니다.

1. 먼저 리눅스에 vnc 프로그램이 깔려 있는지 확인합니다.
# rpm -qa | grep vnc
# rpm -qa | grep vnc
vnc-4.1.2-14.el5
vnc-server-4.1.2-14.el5
앗 이미 깔려 있네요...^-^

rpm 패키지가 없을 경우,
# yum -y install vnc vnc-server
하시면 됩니다.

yum update를 하고나니 업데이트가 되네요...
# rpm -qa | grep vnc
vnc-server-4.1.2-14.el5_3.1
vnc-4.1.2-14.el5_3.1



2. vnc 설정정보가 들어갈만한 경로를 만듭니다.(default 경로 : /root/.vnc)
# mkdir vnc ^_^
# mkdir /root/.vnc
# cd /root/.vnc



3. 비밀번호를 정합니다.
# vncpasswd



4. vi /etc/sysconfig/vncservers 항목에 유저를 추가합니다.



위의 20번째 줄을 복사해서 새로이 하나 만듭니다.





5. 이제 vnc 서비스를 시작합니다.
# service vncserver start


6. 그래픽을 사용하기 위해서 xstartup 파일을 다음과 같이 수정합니다.(주석 3개 제거)




7. vnc 서비스를 재시작한 후 이제 윈도우에서 접속하면 됩니다.
# service vncserver restart



8. 윈도우에서 접속할 시 "해당IP:1" 로 접속합니다.




9. 만약 위와 같이 되지 않을 경우,
방화벽에서 해당 포트가 막혀있을 수 있으니 리눅스 방화벽 및 기타 APP 방화벽에서 로그를 확인하셔야 합니다.

[리눅스] 작업내역 안 남기기, history에 명령어 안 남기기


리눅스에 접속한 후 명령어를 실행하면,
.bash_history에 접속한 이후 실행하였던 명령어 내역이 나오게 됩니다.

특수한 목적으로 history 파일에 이력을 남기지 않으려면
로그아웃 하기 전에

# unset HISTFILE

하시면 됩니다.

또는
cp /dev/null /root/.bash_history 나 vi .bash_history로 해당 파일을 날릴 수 도 있지만
유저가 여러명일 경우 위의 unset 명령을 하시면 접속한 유저의 명령만 clear 할 수 있습니다.

만약 위의 행위를 막으려면,
/etc/profile에

declare -r HISTFILE

을 하시면 됩니다.





또한 쉘 로그인 시,


# export HISTFILE=/dev/null


로 하여도 동일한 효과가 있습니다.
