 Posted: Tue Apr 14, 2009 12:16 pm Post subject: GPRS/UMTS connection with new baselayout |
 |
|
Hello all, I'm getting some troubles trying to configure the net script for my gprs/umts connection.
First of all I'm using a Nokia 6680 as a bluetooth modem and I had no problems to rfcomm connect to it manually and such, so there's nothing wrong on that side.
the real problem here is that I found this guide on gentoo-wiki and after finding that in the scripts there were some errors, I came to this configuration, which should be more or less ok (even net.example reports it):
| /etc/conf.d/net: | config_ppp0=( "ppp" )
link_ppp0="/dev/rfcomm0"
phone_number_ppp0=( "*99#" )
username_ppp0=''
password_ppp0=
pppd_ppp0=(
"maxfail 10"
"debug"
"noauth"
"defaultroute"
"usepeerdns"
# "demand"
"ipcp-accept-remote"
"ipcp-accept-local"
"holdoff 3"
"lcp-echo-interval 5"
"lcp-echo-failure 12"
"noaccomp noccp nobsdcomp nodeflate nopcomp novj novjccomp"
"lock"
"912600"
"nocrtscts"
"noipdefault"
)
chat_ppp0=(
'ABORT' 'BUSY'
'ABORT' 'ERROR'
'ABORT' 'NO ANSWER'
'ABORT' 'NO CARRIER'
'ABORT' 'NO DIALTONE'
'ABORT' 'Invalid Login'
'ABORT' 'Login incorrect'
'TIMEOUT' '5'
'' 'ATZ'
'OK' 'AT+CGDCONT=1,"IP","ibox.tim.it",,0,0'
'OK' 'ATDT\T'
'TIMEOUT' '60'
'CONNECT' ''
'TIMEOUT' '5'
'~--' ''
) |
but with this configuration the pppd daemon seems not to contact the modem ending with this few lines in the logs:
| /var/log/messages: | pppd[3951]: speed 912600 not supported
chat[4041]: abort on (BUSY)
chat[4041]: abort on (ERROR)
chat[4041]: abort on (NO)
chat[4041]: expect (ANSWER)
chat[4041]: alarm
chat[4041]: Failed
pppd[3951]: Connect script failed |
I even found that net.example reports also this:
| /etc/conf.d/net.example: | # Here you should specify what pppd plugins you want to use
# Available plugins are: pppoe, pppoa, capi, dhcpc, minconn, radius,
# radattr, radrealms and winbind
plugins_ppp0=(
"pppoe"
"pppoa vc-encaps"
"capi"
) |
but I have no idea if and which plugins I should enable to make the connection work.
If anyone can help me would be great.
Thanks for your time

There's something nasty going on with this baselayout.
I've successfully started the ppp connection using this one-line command (found somewhere in these forums):
| Code: | | # pppd connect '/usr/sbin/chat -v ABORT "NO CARRIER" "" "AT" OK "AT+CGDCONT=1,\"IP\",\"ibox.tim.it\"" OK "ATDT*99#" CONNECT' /dev/rfcomm0 115200 defaultroute crtscts noauth deflate 0 asyncmap 0 mtu 1500 mru 1500 noipdefault idle 600 |
and the log reports this:
| /var/log/messages: | pppd[12056]: pppd 2.4.4 started by root, uid 0
hcid[27548]: link_key_request (sba=00:0A:3A:63:21:B7, dba=00:12:62:A8:12:FE)
chat[12064]: abort on (NO CARRIER)
chat[12064]: send (AT^M)
chat[12064]: expect (OK)
chat[12064]: AT^M^M
chat[12064]: OK
chat[12064]: -- got it
chat[12064]: send (AT+CGDCONT=1,"IP","ibox.tim.it"^M)
chat[12064]: expect (OK)
chat[12064]: ^M
chat[12064]: AT+CGDCONT=1,"IP","ibox.tim.it"^M^M
chat[12064]: OK
chat[12064]: -- got it
chat[12064]: send (ATDT*99#^M)
chat[12064]: expect (CONNECT)
chat[12064]: ^M
pppd[12056]: Serial connection established.
chat[12064]: ATDT*99#^M^M
chat[12064]: CONNECT
chat[12064]: -- got it
pppd[12056]: Using interface ppp0
pppd[12056]: Connect: ppp0 <--> /dev/rfcomm0 |
so I tried to modify my net script to mimic the same chat commands:
| /etc/conf.d/net: | chat_ppp0=(
"ABORT" "NO CARRIER"
"" "AT"
OK "AT+CGDCONT=1,\"IP\",\"ibox.tim.it\""
OK "ATD*99#"
CONNECT
) |
and the result is this:
| /var/log/messages: | pppd[6278]: pppd 2.4.4 started by root, uid 0
/etc/init.d/net.ppp0[4898]: WARNING: net.ppp0 has started, but is inactive
hcid[27548]: link_key_request (sba=00:0A:3A:63:21:B7, dba=00:12:62:A8:12:FE)
chat[6287]: abort on (NO)
chat[6287]: expect (CARRIER)
chat[6287]: alarm
chat[6287]: Failed
pppd[6278]: Connect script failed |
seems like it doesen't interpret quoted strings with spaces
am I unaware of something?
I think I'll report a bug in this case...

A temporary solution is include in your /etc/conf.d/net the lines like:
| Code: | preup_ppp0(){
pppd connect '/usr/sbin/chat -v ABORT "NO CARRIER" "" "AT" OK "AT+CGDCONT=1,\"IP\",\"ibox.tim.it\"" OK "ATDT*99#" CONNECT' /dev/rfcomm0 115200 defaultroute crtscts noauth deflate 0 asyncmap 0 mtu 1500 mru 1500 noipdefault idle 600
}"
postdown_ppp0(){
killall pppd
} |

bash arrays are not supported by the new baselayout. For instance, your chat_ppp0 should look like this:
| Code: | chat_ppp0="
ABORT 'NO CARRIER'
'' AT
OK 'AT+CGDCONT=1,\\\"IP\\\",\\\"ibox.tim.it\\\"'
OK 'ATD*99#'
CONNECT ''
" |

that's good to know, I'll test it soon, thanks.

If it works, please feel free to update my page on the wiki. Alternativly post back here and I'll give it a going over. It is a little old now.
To be honest I thought it (the page) had gone to bit heaven when the wiki had a few slight problems a while back.
Cheers

NetworkManager 0.7 handles most gprs/umts stuff pretty well. Definitely less painful than manual config.

sorry, networkmanager is not a solution to the problem.
this is a gentoo-related problem (openrc to be more precise).
thanks anyway.
