Im new to the cisco world, working though courses to get my ccna certificate. Bought a cisco 2950 series switch 12.
Im trying to set it up for ssh but having issues with the crypto key command. Ive googled looking for answers and found that i had to download the cryptographic image. Ive downloaded that from cisco.com and now have the .bin file but not sure what to do with it or how to implement it into the switch.
Any and all help is much appreciated!

Hi Jeff,
you have to install tftp service on a PC and then issue the command: copy tftp flash on privilage mode to upload the new IOS version into the switch
when you issue the command copy tftp flash you have to have to put the values of each parameter the switch will ask you, such as: the ip address of the tftp server (it can be windows 2000 pro, xp, 2003 or 2008) and then the uploaded file name (it will be the name of the .bin file)
rate please if it is helpful
regards,

Hello Jeff,
Here are some steps:
check directory files
2950#dir flash:
obtain space
2950#delete flash:name_of_ios.bin
2950#delete flash:html/*
sending new IOS
2950#archive tar /xtract tftp://your_ip/name_of_ios.tar flash:
setting the new IOS to boot
2950#dir flash:
check the name of bin file
2950#conf t
2950(config)#boot system flash:name_of_ios.bin
2950(config)#end
checking the file name (IOS)
2950#sh boot
BOOT path-list: flash:name_of_ios.bin
2950#wr mem
Building configuration...
[OK]
2950#reload
Proceed with reload? [confirm]
enabling ssh
2950#conf t
2950(config)#crypto key generate rsa
[OK]
Regards.

Thanks i will give these ideas a shot..
I will get back on how they worked for me once i give them a shot, workin full time doesn't give much time but the nights to work through this stuff.
When i set up the tftp server on the pc, will it matter if im running win7 not a previous os?

So i've been giving this a try and sort of making some headway... Somewhat figured out the TFTP Server (downloaded solarwinds tftp) and have it installed and opened, linked the TFTP file to the folder the crypto .bin file is in and started the server. I've ping'd the address its showing in solar winds (which corresponds to my pc ip) but i keep getting an access error.
I've made an acception in windows firewall and that didnt work, i shut off windows firewall and nothing, ive forwarded port 69 in my router.... im kind of stumped at this point... everything i google doesnt have any useful info, really only shows the the crypto key generate rsa command and so on...
I thought i had sort of a handle on this now, but apparently i was wrong. This online course im taking seems to be very vauge with details, though i've been working through the Cisco CCENT quick reference notes and it still doesn't mention anything about a TFTP server.
