The remote computer requires Network Level Authentication, which your computer does not support.

Pentru a activa Network Level Authentication pe un calculator cu Windows XP trebuie urmati urmatorii pasi:

1. Daca nu aveti instalat Windows XP Service Pack 3 trebuie sa il downloadati si sa il instalati.
2. Porniti editorul de registrii
       Start -> Run -> regedit [ENTER]
3. Cautati si editati urmatoarea cheie de registrii
       HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\Security Packages
4. In campul Value Data sub restul valorilor care sunt deja trecute adaugati tspkg apoi apasati OK
5. Cautati si editati urmatoarea cheie de registrii
       HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SecurityProviders
6. In campul Value data dupa restul valorilor care sunt deja trecute adaugati credssp.dll
7. Inchideti editorul de registrii si restartati calculatorul

Mai jos sunt pasii care trebuie urmati pentru schimbarea portului a serviciului Remote Desktop la Windows.

Versiunile de Windows pentru care este valabil acest tutorial sunt:

• Microsoft Windows XP Professional
• Microsoft Windows XP Professional x64 Edition
• Microsoft Windows Remote Desktop Connection for Macintosh
• Microsoft Windows Server 2003, Standard Edition (32-bit x86)
• Microsoft Windows Server 2003, Standard x64 Edition
• Windows Server 2008 Enterprise
• Windows Vista Enterprise
• Windows Vista Enterprise 64-bit Edition
• Windows Server 2008 R2 Enterprise
• Windows 7 Enterprise
• Windows 7 Professional

Pasii care trebuie urmati sunt:

1. Porniti editorul de registrii
       Start -> Run -> regedit [ENTER]
2. Cautati si editati urmatoarea cheie de registrii
       HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber
3. In meniul de editare (Modify) selectati Decimal, treceti portul dorit la Value Data si apasati OK
4. Inchideti editorul de registrii
5. Modificati setarile la Firewall si adaugati noul port pentru a va putea conecta.
6. Restartati calculatorul

Nota: Cand incercati sa va conectati la un calculator care are alt port decat portul default dupa adresa IP se pune caracterul ":" urmat de portul pe care ruleaza serviciul Remote Desktop (Click pentru exemplu)

Vom instala pachetele necesare folosind FreeBSD Ports

Instalam colectia de porturi FreeBSD Ports

root@bsdpc[~/work/src] # portsnap fetch && portsnap extract && portsnap fetch update

Instalam SNMPd, p5-SNMP-Util, p5-SNMP_Session, p5-SNMP-Simple din FreeBSD ports

root@bsdpc[~/work/src] # cd /usr/ports/net-mgmt/net-snmp
root@bsdpc[/usr/ports/net-mgmt/net-snmp] # make install clean
root@bsdpc[/usr/ports/net-mgmt/net-snmp] # cd /usr/ports/net-mgmt/p5-SNMP-Util
root@bsdpc[/usr/ports/net-mgmt/p5-SNMP-Util] # make install clean
root@bsdpc[/usr/ports/net-mgmt/p5-SNMP-Util] # cd /usr/ports/net-mgmt/p5-SNMP_Session/
root@bsdpc[/usr/ports/net-mgmt/p5-SNMP_Session] # make install clean
root@bsdpc[/usr/ports/net-mgmt/p5-SNMP_Session] # cd /usr/ports/net-mgmt/p5-SNMP-Simple/
root@bsdpc[/usr/ports/net-mgmt/p5-SNMP-Simple] # make install clean

Instalam MRTG din FreeBSD ports

root@bsdpc[~/work/src] # cd /usr/ports/net-mgmt/mrtg/
root@bsdpc[/usr/ports/net-mgmt/mrtg] # make install clean

Copiati codul de mai jos in /usr/local/share/snmp/snmpd.conf

Code:

syslocation YourCountry
syscontact YourName - you@yourdomain.tld
rwcommunity public 127.0.0.1
rwcommunity public 10.0.0.0/24

In loc de 10.0.0.0/24 treceti IP-ul sau range-ul de ip-uri din reteaua dumneavoastra pentru care doriti sa generati graficele de trafic

Copiati codul de mai jos in /usr/local/etc/mrtg/mrtg.cfg iar in loc de msk0 la MRTG_INT_DESCR=”msk0” treceti identificatorul de la placa de retea a systemului dumneavoastra.

Code:

LoadMIBs: /usr/local/share/snmp/mibs/UCD-SNMP-MIB.txt
WorkDir: /usr/local/apache2/htdocs/stats
Options[_]: growright, bits, nopercent, nobanner, noinfo, pngdate
PNGTitle[_]: host.domain.tld
Background[_]: #FFFFFF
Timezone[_]: Europe/Europe
Colours[_]: GREEN#00FF00,BLUE#0066FF,DARK GREEN#33FF33,PINK#FF66FF
XSize[_]: 600
YSize[_]: 180
YTics[_]: 12
Target[speedused]: 1:public@127.0.0.1:
SetEnv[speedused]: MRTG_INT_IP="" MRTG_INT_DESCR="msk0"
MaxBytes[speedused]: 125000000
AbsMax[speedused]: 230000000
Title[speedused]: Traffic Analysis
PageTop[speedused]: Traffic Analysis
Options[speedused]: growright, bits, nopercent, nobanner, noinfo, pngdate

Editati /etc/rc.conf si adaugati snmpd_enable= “YES”, apoi pornim serviciul SNMPd

root@bsdpc[~/work/src] # /usr/local/etc/rc.d/snmpd start

Creem directorul unde se vor salva graficele MRTG

root@bsdpc[~/work/src] # mkdir /usr/local/apache2/htdocs/stats

Rulam de 2-3 ori scriptul MRTG pana cand acesta nu va ma da erori sau avertizari, la inceput acestea apar doarece nu gaseste fisierele de loguri si imaginile mai vechi

root@bsdpc[~/work/src] # /usr/local/bin/mrtg /usr/local/etc/mrtg/mrtg.cfg

Editam /etc/crontab si adaugam scriptul MRTG la crontab pentru ca acesta sa ruleze la fiecare 5 minute si sa actualizeze graficele

*/5 * * * * root /usr/local/bin/mrtg /usr/local/etc/mrtg/mrtg.cfg

root@bsdpc[~/work] # wget http://bwmod.sourceforge.net/files/mod_bw-0.7.tgz
root@bsdpc[~/work] # tar zxvf mod_bw-0.7.tgz
root@bsdpc[~/work] # cd mod_bw

Default modulul nu functioneaza sub apache 2.x, acesta afiseaza o eroare de forma:

httpd: Syntax error on line 57 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/mod_bw.so into server: /usr/local/apache2/modules/mod_bw.so: Undefined symbol "apr_atomic_add"

Pentru a evita aceasta eroare editam fisierul mod_bw.c de unde stergem urmatoarele linii (liniile de la 61 pana la 68):

/* Compatibility for ARP < 1 */
#if (APR_MAJOR_VERSION < 1)
    #define apr_atomic_inc32 apr_atomic_inc
    #define apr_atomic_dec32 apr_atomic_dec
    #define apr_atomic_add32 apr_atomic_add
    #define apr_atomic_cas32 apr_atomic_cas
    #define apr_atomic_set32 apr_atomic_set
#endif

Compilam si instalam modulul dupa care se modifica fisierul de configurare apache pentru a adauga limitarile dorite si se da restart la apache.

root@bsdpc[~/work/mod_bw] # /usr/local/apache2/bin/apxs -cia mod_bw.c
root@bsdpc[~/work/mod_bw] # pico /usr/local/apache2/conf/httpd.conf
root@bsdpc[~/work/mod_bw] # /etc/rc.d/httpd restart

Cateva exemple de configurare:

## Se adauga in sectiunea virtual host-ului ##

## Pentru limitarea fiecarui vizitator la 128KB/s pe un virtual host
BandwidthModule On
ForceBandWidthModule On
Bandwidth all 128000
MinBandwidth all -1

## Pentru limitarea extensiilor avi, mpg la 64KB/s
BandwidthModule On
ForceBandWidthModule On
LargeFileLimit .avi 1 64000
LargeFileLimit .mpg 1 64000

Job Done. Enjoy!

Editati fisierul de configurare al serverului WEB Apache si adaugati urmatoarele linii:

LoadModule php5_module        modules/libphp5.so   #### De obicei aceasta linie este deja adaugata prin procesul make install
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps

Restartam serverul Apache si verificam incarcarea modului php5_module

root@bsdpc[~/work/php-5.3.8] # /etc/rc.d/httpd restart
root@bsdpc[~/work/php-5.3.8] # /usr/local/apache2/bin/httpd -M |grep php

Syntax OK
