I tried my best to get atftpd working, but even using the defaults, the router tying to talk to the atftpd server kept saying "no such file or directory". I gave up, and used an XP Pro VM with Solarwinds TFTP server, and it worked great. I really need to get tacacs+(and radius if possible) running on the Mint17 VM, Since my 2008R2 VM runs PRTG swimmingly well, but it keeps giving me stupid errors about NPS that I can't seem to fix, I need to switch to another OS.

I installed atftpd, tacacs+, and radius off the Mint 17 ISO via the software manager, and it says they are installed, but I have no idea how to use them.

Help, please?

Perhaps this may help ... tos-6.html ... -isps.html

Not exactly Linux Mint, but it may give you some clues. And if you do work it out, please report back and let us know how you did it .

I never did get atftpd working properly, but it turned out I was using the wrong command for tacacs+ in Linux Mint. It's actually "tac_plus" (minus the quotes, obviously). Radius also works well, it just requires a lot more setup work than using the 2008R2 for that. It's almost a no brainer in 2008R2.

So far, I've gotten Windows 2008R2, Haiku, Linux Mint 17, Netware 5.1, Windows XP (using IP Blue softphones and Solarwinds TFTP) and an NT4 workstation with the client32 and nwadmin (minus IPX/SPX) working swimmingly in my topology, along with turning a 3745 into a CME for the soft IP phones. So far, a very happy camper! :)

I just wish I could get a 6500 Cat working (for private vlans), but I understand the issues with getting that to work (custom ASICs and all that). I ended up getting a different simulator to practice with that.


BTW, here's an article from Cisco support about configuring the CME device via the CLI. Hope this helps anybody else who might be having problems. And you *definitely* need to use the format/flash technique mentioned in this post, as well as edit the memory, nvram, pcmcia, exec area, and hypervisor settings, or it *will* fail on your first attempt without it.


Also, PRTG installs just fine on 2008R2, and works great. I was able to monitor all devices in the topology (SNMP traps, utilization, netflow/sflow, etc...) from both the Haiku VM and Mint17 VM via their web browsers. Make sure you DON'T install IIS7, or it'll cause PRTG admin and console to never start, due to errors with IIS7.
