VPN Cisco - Disconnessione

[Quivalent]

Salve,
Spero di non spammare con un'altro post inutile (Ho cercato ma non ho trovato nulla  )

In breve, uso per lavoro la VPN Cisco a cui mi connetto normalmente (Con qualsiasi client vpn per cisco) il problema e' che dopo 2-3-5 minuti mi sconnette dalla VPN.

Qualcuno sa darmi qualche indicazione?

Quali client hai usato?
Appare qualche messaggio di errore?
Hai provato a dare una spulciata ai log del client?

[Quivalent]

Uso il network managment di ubuntu con il componente aggiuntivo per Cisco.

Non mi da alcun messaggio di errore.

nella /var/log/syslog ho trovato tracce del networkmanagment

riporta la voce: vpnc[21436]: connection terminated by dead peer detection

continuo a controllare

Uso il network managment di ubuntu con il componente aggiuntivo per Cisco.

Pacchetti network-manager-vpnc e network-manager-vpnc-gnome?

nella /var/log non so quale log guardare..

Se usi il Network Manager il log da terminale dovresti leggerlo (credo) così:

Codice: Seleziona tutto

cat /var/log/syslog | grep -i networkmanager

Hai provato a attivare la connessione da terminale richiamando direttamente vpnc?

Hai provato ad usare il client VPN della Cisco?

[Quivalent]

Il Client e' il network-manager-vpnc

Hai provato ad usare il client VPN della Cisco?

si ho provato molti client e mi danno tutti li stesso problema..

Nel log ho trovato:

Ti posto i passaggi che mi ero segnato a suo tempo per utilizzare il client vpnc da terminale, spero siano ancora validi, non ho la possibilità di verificare

Codice: Seleziona tutto

Install VPNC and connect to Cisco VPN Concentrator (http://joepcremers.nl/wordpress/?p=1845)

$ sudo apt-get install vpnc

$ sudo apt-get install libgcrypt11-dev

$ sudo apt-get install resolvconf (non serve)

$ mkdir vpncdir

$ cd vpncdir

$ wget http://www.joepcremers.nl/wordpress/wp-content/files/cisco-decrypt.c

$ gcc -Wall -o cisco-decrypt cisco-decrypt.c $(libgcrypt-config — libs — cflags)

$ chmod +x cisco-decrypt

$ sudo cp cisco-decrypt /usr/bin

$ wget http://www.joepcremers.nl/wordpress/wp-content/files/pcf2vpnc

$ sudo chmod +x pcf2vpnc

$ sudo cp pcf2vpnc /usr/bin

Convert your cisco .pcf file to .conf

$ sudo pcf2vpnc workvpn.pcf workvpn.conf

$ sudo cp workvpn.conf  /etc/vpnc/



Start vpnc and connect using workvpn.conf

$ sudo vpnc workvpn

Enter username for <vpn> :
Enter password for <vpn>:
VPNC started in background (pid: 6092)…


Magari il tuo problema è legato a Network Manager e non strettamente a vpnc
