Linux下Telnet E680i经常断的解决方法-红联Linux系统门户

　　在Linux下虽然可以使用<>的办法联接到小i, 但是使用过程中却经常无缘无故的中断. 并且在Linux机器上ifconfig的结果中frame的值比较大:

引用:
usb0 Link encap:Ethernet HWaddr 3E:5D:E9:F6:BB:29
inet addr:192.168.1.5 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::3c5d:e9ff:fef6:bb29/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1400 Metric:1
RX packets:199 errors:18 dropped:0 overruns:0 frame:18
TX packets:272 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:13697 (13.3 KiB) TX bytes:19410 (18.9 KiB)

可设置Linux主机的mtu为1400, 并设置小i的txqueuelen为1000来绕过这一问题. 在Linux机器上运行命令

引用:
ip link set usb0 mtu 1400

telnet到小i后运行命令

引用:
ip link set usbl0 txqueuelen 1000

小i本身不带ip命令, 需要从pashkovsky.com/e680/下载.

在Linux机器上的运行过程如下:

引用:
blueice:~# ifconfig usb0
usb0 Link encap:Ethernet HWaddr 8A:20:27:42:C1:C8
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

blueice:~# ip link set usb0 mtu 1400
blueice:~# ifconfig usb0
usb0 Link encap:Ethernet HWaddr 8A:20:27:42:C1:C8
BROADCAST MULTICAST MTU:1400 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

在小i上的操作过程如下:

引用:
blueice:~# telnet 192.168.1.2

另外, 在完成以上网络设置之后, 可以方便的使用samba挂载小i的文件系统, 命令如下

mount -t smbfs -o username=root,password="",codepage=936,iocharset=cp936 //192.168.1.2/system /mnt/ia
