Issues in inatalling SDM

Hi,

I was trying to install SDM in 877 router for utilizing the GUI based firewall stuffs which is found in the SDM package.

I could able to install the SDM in my laptop but while installing to my router i get a popup message like "RCP is denied through the connected interface. Update cannot proceed" and closes by itself.

Hope some one will be helping me to fix the issue.

Thanks

Re: Issues in inatalling SDM

Hi Rajesh,

Question:

when I try to install SDM (version 2.2a, March 2006) on my router I get error message:

RCP is denied through the connected interface. Update can not proced.

Reason:

These issues will be encountered for IOS images 12.4(4)T and above. SDM uses RCP for installation operations. This problem occurs because the fix for CSCdu34824 in recent Cisco IOS releases has changed RCP behavior. Because of this change, if the RCP client

uses a non-privileged port , the router RCP server does not respond and the above issues occur.

>>> thanks to sikrishn for details on this issue <<<

Workaround:

1) use the copy tftp flash command to copy SDM related files from PC to router.

example: Router# copy tftp:/// flash:

2) downgrade the router to older IOS, eg. 12.3, then use the usual SDM setup and upgrade the router again.

On Cisco 831 Router your flash: will contain these files when SDM 2.2a ist installed.

System flash directory:

File Length Name/status

1 7756516 c831-k9o3y6-mz.123-11.YS.bin (this is the IOS, not the SDM!)

2 1038 home.shtml

3 1721 sdmconfig-83x.cfg

4 113152 home.tar

5 234040 attack-drop.sdf

6 1007616 common.tar

7 4049920 sdm.tar

8 812544 es.tar
