有了操作系统,开发板和宿主机就基本没有区别了,:-)。所以我直接就把在fedora下测试通过的三个脚本稍加修改搬到了开发板上,毫无疑问的一次拨通,:-),有了操作系统,就是爽呀。微处理器是at91rm9200,gprs模块是mc39i。
当然如果内核不支持ppp拨号,则要重新编译内核,添加对ppp的支持,
Network device support-->
<*> PPP (point-to-point protocol) support
[*] PPP multilink support(EXPERIMENTAL)
<*> PPP support for async serial ports
<*> PPP support for sync tty ports
<*> PPP Deflate compression
<*> PPP BSD-Compress compression
然后重新烧写新生成的内核映象。
再把我的脚本粘帖一遍吧。这样就不怕丢了,:-)。
/mnt/nfs/myppp/ppp-on
#!/bin/sh
#
# Script to initiate a ppp connection. This is the first part of the
# pair of scripts. This is not a secure pair of scripts as the codes
# are visible with the 'ps' command. However, it is simple.
#
# These are the parameters. Change as needed.
TELEPHONE=*99***1# # The telephone number for the connection
ACCOUNT= # The account name for logon (as in 'George Burns')
PASSWORD= # The password for this account (and 'Gracie Allen')
LOCAL_IP=0.0.0.0 # Local IP address if known. Dynamic = 0.0.0.0
REMOTE_IP=0.0.0.0 # Remote IP address if desired. Normally 0.0.0.0
NETMASK=255.255.255.0 # The proper netmask if needed
#
# Export them so that they will be available at 'ppp-on-dialer' time.
export TELEPHONE ACCOUNT PASSWORD
#
# This is the location of the script which dials the phone and logs
# in. Please use the absolute file name as the $PATH variable is not
# used on the connect option. (To do so on a 'root' account would be
# a security hole so don't ask.)
#
DIALER_SCRIPT=/mnt/nfs/myppp/ppp-on-dialer
#
# Initiate the connection
#
# I put most of the common options on this command. Please, don't
# forget the 'lock' option or some programs such as mgetty will not
# work. The asyncmap and escape will permit the PPP link to work with
# a telnet or rlogin connection. You are welcome to make any changes
# as desired. Don't use the 'defaultroute' option if you currently
# have a default route to an ethernet gateway.

如果ping不通的话,配置一下network就ok了。:-)
/etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=localhost.localdomain
GATEWAY=
GATWAYDEV=
关键是后边这两个要空着,这样就会使用ppp分配的网关了,也就可以ping通了。
