actualy my problem is with busybox package.
i have a modem who busybox intalled on it. i can add a static route on it with route add -net x.c.v.b netmask 255.25.255.0 gw n.m.k.l
and it work without any problem . but afre rebooting the modem that route remove from routing table . i have this problem with any folder and file who i create on it . at first every thing seems ok befor any reboot . after reboot you cannot see that file or folder who you add befor reboot . i think aome thing will overwite every thing in boot proccess


i have problem With it ,i dont have any permission , for example i cant save
Exapmle :
route add -net 10.2.3.0 netmask 255.255.255.0 gw 11.0.55.5
after reboot it . i dont see in the my route

or
i cant access to some command
please help

Well, it helps to know what distro you have. Here is how you would do it for fedora:
http://www.linuxhomenetworking.com/w..._Static_Routes

If you need help forming a google search 'Permanent Route' and then your distro name.

If you need some more help just give us your distro name and we can go from there.

If you are having trouble with some commands give us the error and what commands you are trying to do.

I tried busybox a long time ago when working with embedded system.

From memory, you should be able to choose what program to add to busy box during install.

With SnapGear I believe you just do that during the configuration of the Kernel. I'm not sure what happen if you manually download and install it.

Busybox is simply a compilation of multiple program into one large program to save diskspace. So you should be able to find the program as a symbolic link. For example "ftp" becomes a symbolic link to "busybox ftp" or something like that.

p.s. when you say you don't have permission do you mean you can't find "chmod"?

I just checked the busybox website, your version of busybox might be a bit outdated. You should download the newer version, it might appeared large. But when you "choose" the programs to add the compiled binary shouldn't be so large.

Good luck.

hi
actualy my problem is with busybox package.
i have a modem who busybox intalled on it. i can add a static route on it with route add -net x.c.v.b netmask 255.25.255.0 gw n.m.k.l
and it work without any problem . but afre rebooting the modem that route remove from routing table . i have this problem with any folder and file who i create on it . at first every thing seems ok befor any reboot . after reboot you cannot see that file or folder who you add befor reboot . i think aome thing will overwite every thing in boot proccess .

I havn't use Linux in a while, other than using one as a server.

From memory and from Benjithegreat98's link, the static route is always remove after you reboot your Linux system. That is normal on a standard Linux system.

If you read Benjithegreat98's link, you need to add the route to /etc/sysconfig/network-scripts/route-* filename.

For the file and folder disappearing. It's likely you are using a "ram harddisk". That means the only time you use your harddisk is durng boot when it copys the Linux Kernel and all configuration file to ram.

Hope this helps.

It also might be a standard harddrive which is always overwrite by a saved default harddrive.

If you have so much control over your modem and created error, the vendor will get alot of complaints.

There must be a way to save the change through interface provide by your modem.

hi
I read your idea
but unfortunatly the directroy that you have mentioned doesnot exist on or system
what is your solution?

I dont' know. What modem is it exactly. If the vendor meant to let you add route there should be an interface provided by your modem which let you save your configuration in a file.

You can try to manual add the route in the Linux boot script. I'm not sure if the bootscrpt is overwrited during boot too though.

Is this a modem/router that runs linux? Post the make and model number of your modem.

As previoulsy stated busybox is an executable that contains stripped down versions of the basic unix core utilities. It is designed to run on embedded sytems with low memory resources. Either the command your trying to execute is not included or there isn't a path environment variable configured. This modem runs from a flash memory chip configured as hdc and contains two partitions. The OS runs from RAM similar to a liveCD so creating any files or folders is never written back to the flash memory chip.

Without knowing specific information on how the data is stored in flash or how the flash memory is configured I can not tell you how to save your files / and folders.

pleae tell me what kind of information do you need?

Post the make and model number of your modem/router.

Model Is Satpath2000 . This is satllite modem.
