Ubuntu and GNS3

in CCNA & CCENT
I am trying to save some money by using GNS3 on weekdays and real equipment on weekends.
I installed GNS3v0.7.1 on my Win7 64bit. It runs fine, but from time to time the console(putty) crashes on particular router. So I decided to install Ubuntu 10.04 x64, and installed GNS3. I followed this guy's installation, and so far so good.
My question is how do I use teraterm or may be putty as my console for GNS3 Ubuntu?
And for GNS3 users here, what OS do you use?
Thanks

Optionsstuh84 Member Posts: 503GNS3 is just an overlay for Dynamips, so whatever ports each router is posted on, you should just be able to telnet to them, like so: -
telnet localhost 2001
Just open up the terminal and try it from there.
As for the OS's I use? Fedora 12 has been what I used to get me through the BSCI exam on the CCNP, I used Ubuntu 8.04 for the CCNA, and I'm hoping in future I can start using ESXi if I get a powerful enough server, and run it within a CentOS VM.
Bear in mind, I'm doing this ALL in Dynamips though, I don't use GNS3 by choice.Work In Progress: CCIE R&S Written

The first 4 in my list are the ports of the routers.
Alternatively, learn dynagen and dynamips rather than GNS3, then you aren't relying on what the GUI does, only what you configure.Work In Progress: CCIE R&S Written

Main reason is because VMWare has such a foothold in the corporate world, I want to get involved in it so I have some experience of it.
Plus, I've been using VMWare desktop (Fusion, Player, Server) and Workstation versions for years, so I have a lot of VMs already that while I dont use all the time, it would be nice to just chuck them on and boot them up without any conversion etc.Work In Progress: CCIE R&S Written

I am thinking of doing it uesterday, but what I have installed is VirtualBox, and it is kind of slow.
Is VMware player runs smoother than VirtualBox?Studying:

You would be able to do that, but you are then limiting what GNS3 can use in terms of resources to how you have set the VM. I have a server I use which is almost dedicated to Dynamips, if at all possible it would be a better route to have a box which does Dynamips alone, or at least not much else (I'm using an laptop with a broken screen, but it has a C2D and 2GB of ram, perfect for the task at the moment).Work In Progress: CCIE R&S Written

Optionsthehourman Member Posts: 723The reason I asked is that, I don't like the Gnome bootloader. I simply can't restarting my PC and switching between two OSes. And I don't have the cash for dedicated dynamips server. I don't even know how to use it. lol.
I have spent all my tax money on my lab equipments. The only reason why I am learning GNS3 is, so that I can save up some money by reducing my electric bill.

Yeah I know what you mean, I've not got a lot myself due to now having a mortgage, what I use for servers and the like are hand-me-downs. Maybe keep an eye out to see if anyone is getting rid of their old laptop or something? Even a Core Duo can run a good 10 routers if you set it up right.
I think as long as you dedicate enough resources to the VM though (and if the VM can use multi-core processors) you may be onto a winner.Work In Progress: CCIE R&S Written

Optionsthehourman Member Posts: 723I already setup the VMware player and installed Ubuntu 10.04 64bit.
One more question, a minutes ago I could control my mouse back and forth on Windows and VMware(Ubuntu) without using hotkeys. And now for some reason, if I want to go back to Windows, I have to use ctrl+alt to exit the VMware window.
What should I do to go back to previous settings?
EDIT: A simple VMware restart fixed the problem.
How do I share my files from Windows 7 to VMware Ubuntu?Studying:

To all,
Thanks a lot guys.
My GNS3 seems to be working pretty well with my VMware.
The specs of my VMware is: 2 cores of my CPU, 3GB of RAM, and 7GB HDD.
When I opened 12 routers, it ran smoother than my Win7, and the consoles did not drop like on Win7. When everything is running Ubuntu's sys monitor says that both core are running at 100%, and the RAM is about 75%.
Man, I am really happy now. I do have my mini-practice lab now.
EDIT:
That ROXterm works like a charm, love it.
Also, I remember some here posted a new terminal emulator that is similar to ROXterm or may be it was ROXterm(can't remember).
Does anyone know where that thread is?Studying:

I've read in a few places that you can play the cbtnuggets in mplayer. You just need to get the good, bad, and ugly codecs for it. -

However, under VMware player, everything seems to run the way I wanted them to run. Therefore, I just deleted my Ubuntu partition, and rewrite my bootloader to get rid of that grub bootloader.Studying:

Hmm, I think you are right. I was assuming that it is possible to create a loopback interface in Linux and just point Minicom to that interface. But I've not been able to find any information that supports this. -
Optionsthehourman Member Posts: 723How do I make my router act like a switch on GNS3?
I used the 3640 with 16SW module, and I couldn't make a vlan the way I want to.
Do I have make a vlan under privilege mode and using the vlan database command?
How come the guy from youtube can use the show vlan command on his GNS3 router?
I tried to use the sh vlan command and it says Ambiguous command.Studying:

OptionsQHalo Member Posts: 1,488Honestly I'd just **** GNS3. If your topology is static its much easier to just create a net file and use that.

Yea, I was able to get about 7-8 routers going in windows 7 without eating up too much resources but GNS3 seemed buggy. Half the routers I would put in my topology the console didn't work right and I'd spend more time just trying to get all the routers console lines to work than actually labbing.
Finally put Ubuntu 10.04 on my desktop. I've tried 12 routers without a hitch, CPU didn't even hit 50%. Haven't had a single problem. I do like Windows 7 but I now mainly use Ubuntu. It's slick.
As far as CBTnuggets goes, I just converted those to MP4. -
