Bug in GNS3-0.8.4-RC3 (and a couple of questions).

While trying to get a handle on the VirtualBox console settings I came across a possible bug (see below).

First, when and why would a user select "Enable console support" without also choosing "Enable console server?" What can be done with Enable console support if you don't also enable the server option? I've found that I need both options selected to connect to say Linux TinyCore using the console port (using telnet localhost 3501 for example).

The Bug: Tested on OS X and Linux:
If I only select "Enable console server" under VirtualBox Guest settings I get the following error when starting my Linux VurtualBox guest:
Linux_1: error from server 127.0.0.1:11525: 209-unable to start instance 'Linux_1'

Thanks,
Jason

I am aware that many people reported crashes on Win8 64-bit. Can you try the standalone 32-bit version?

Thanks,

0.8.4 RC3 Windows 7 64 bits version
Some new goodies:

+Topology screenshot taken at each saving
+VPCS current directory changed to 'working', allowing to very easily load/save configuration file, instead of having to insert the whole path before it

Some issues:

-Stats when hovering over a running device:
MiB --> MB seems more appropriate
KiB --> KB seems more appropriate
ASA has been forgotten
-Deleting a device from the topology and saving:
configs\device-name.cfg not deleted
-Hiding the hostname on a host and saving:
hostname reappears
-Using 'Suppr' key within a textbox:
not working
-Unbase feature for ASA projects:
resets gns3.ini to default
buggy:

I still do not get the point: does that mean we cannot share ASA projects without it (when operational)?
-Superputty:
column width of first lines still significantly reduced

-Ghost files:
still saved in working folder instead of Dynamips (or Qemu) working directory
why some 3725 ghost files are saved when only an ASA is running?

GNS3 Working directory

There seems to be two problems with working directory in GNS3 0.8.4 RC3, in addition to but related to actionmystique's post above.

1. Irrespective of whether you check the [x] Save nvrams and virtual hard drives option, it seems that the directory called Working is created off your project directory anyway - I don't have a problem with the directory being created (since it is used to store vpcs.hist and VPCS saved configs), but it is also used as the dynamics working directory, effectively overriding the option set in Edit | Preferences (Dynamips).

2. Furthermore, the directory doesn't get cleaned up, even if the option to [x] Automatically clean the working directory is set.

Here is a sample: 226MB of trash left after stopping all devices, then quitting GNS3 gracefully

Code:
2013-05-26  04:45         8,388,608 c7200_R1_bootflash
2013-05-26  04:45        67,108,864 c7200_R1_disk0
2013-05-25  18:46                 0 c7200_R1_lock
2013-05-26  04:45           131,072 c7200_R1_nvram
2013-05-26  04:45         8,388,608 c7200_R2_bootflash
2013-05-26  04:45        67,108,864 c7200_R2_disk0
2013-05-25  18:46                 0 c7200_R2_lock
2013-05-26  04:45           131,072 c7200_R2_nvram
2013-05-26  04:45         8,388,608 c7200_R3_bootflash
2013-05-26  04:45        67,108,864 c7200_R3_disk0
2013-05-25  18:46                 0 c7200_R3_lock
2013-05-26  04:45           131,072 c7200_R3_nvram
              12 File(s)    226,885,632 bytes

@rednectar: If you check "[x] Save nvrams and virtual hard drives", the related files are saved in the working directory of the current project and loaded the next time you load GNS3 with this project.

You cannot save these files in the working directory of Dynamips, otherwise they would overwrite other files named in the same way from other projects.

So it seems perfectly natural to have these files depend on your project directory. And *nvram*, *disk0* ... are not really trash since you've asked for their saving...

Yet, I agree with your statement about different working directories (the project and Dynamips) regarding temporary files, such as all the *ghost* files created only when Dynamips is running; they should be saved using the Dynamips working folder regardless of the "[x] Save nvrams and virtual hard drives" option, except if we consider that running multiple instances of GNS3 is allowed, in which case we could face the same 'overwriting' issue as stated above.

I already asked Jeremy to solve that here http://forum.gns3.net/post19798.html#p19798, but he answered that implementing that solution would mean adapting Dynamips (a very little bit) and he's reluctant to do so.

I'm convinced that this tiny evolution should not put the code stability at risk.

@Jeremy: I wish we could have the 'nvram' files of ASA saved the same way they are saved for routers. This could probably solve an issue I had recently described here: http://forum.gns3.net/topic6385.html

@ actionmystique - I screwed up by missing ONE important word in my last post:

Quote:
2. Furthermore, the directory doesn't get cleaned up, even if the option to [x] Automatically clean the working directory is set.


What I MEANT to say was:

2. Furthermore, the directory doesn't get cleaned up, even if the option to [ ] Automatically clean the working directory is NOT set.

The thing is that RC3 is saving these files EVEN WHEN [ ] Save nvrams and virtual hard drives is NOT checked!!!!!!!

I'm also wondering if the working directory is the right place to keep vpcs files - because once someone has saved a startup.vpcs, it should become part of your "configuration" not your "working" if you know what I mean.... Just a thought at the moment...I'm not totally convinced because we already keep VLAN config in the Working directory.

Does anyone get problems with embedded SW/router (3725)...and vbox host connection in vlans???
Seems it uses IOS image what is by default assigned to 3725 router...isn't t?
the problem is that, it wont work with DHCP, such problem wasn't before...

Please explain me about reserved first NIC for Vbox NAT...what does it mean...and why?
Also no potion under configuration of host I can choose minimum 2NICs...

Last GNS vers I always used first nic to connect host to my labs...

Only one problem is why routerswitch want work? tested severeal IOS 3725...same unluck result, connection Host - switch doesnt work....
what wasnt before...

tested to use 3660 with NM 16 port card...works like charm...DHCP connection etc...

Please adivse, what happens with embedded R/SW 3725??


seems I got problem...
This is hardcoded r/sw startup config problem....
when I take clean 3725 with 16 switch module...it works like charm...

Where I can change 3725 startupconfig what is loading by default on R/SW ??????

Because this hardcoded startup config is useless...
If I did changes, for example turning on ip routing after reload it returns back with no ip routing and no serivice dhcp..
why you did that ?!?!?!

I tried to save projects with [ ] Save nvrams and virtual hard drives NOT checked on Windows 7:

- with only 7200 routers, only an empty working directory is created;
- with only 3725 switches, a working directory is created with some files in it, indeed.

Regarding VPCS, only the current configuration file related to the current project is saved in the working directory: IP addresses, masks, default gateways...

I'm excited about this new release candidate and appreciate all the work you all put into this great application. I thought I'd share the below settings in case there are other people who, like myself, got a little confused on the configuration after I mucked around with it.

I've installed GNS3-8.4-RC3 on a Macbook Pro running OSX Version 10.8.3 and used the below Qemu configuration on the General Settings tab to get it working correctly (remember to use the forward slash / at the start of the path).

Path to Qemuwrapper: /Applications/GNS3.app/Contents/Resources/qemuwrapper.py
Working Directory: /tmp
Path to qemu: /Applications/GNS3.app/Contents/Resources/Qemu-0.11.0/bin/qemu
Path to qemu-img: /Applications/GNS3.app/Contents/Resources/Qemu-0.11.0/bin/qemu-img
Qemuwrapper port: 10525 TCP
Base console port: 3001 TCP
Base UDP port: 40000 UDP
IP/host binding: 127.0.0.1
External Qemuwrapper: localhost:10525
Registered external Qemuwrapper: localhost:10525

I noticed that this release also contained Qemu version 0.14.1, so I set the Qemu configuration on the General Settings tab to the below and it worked with that version as well (remember to use the forward slash / at the start of the path).

Path to Qemuwrapper: /Applications/GNS3.app/Contents/Resources/qemuwrapper.py
Working Directory: /tmp
Path to qemu: /Applications/GNS3.app/Contents/Resources/Qemu-0.14.1/bin/qemu-system-x86_64
Path to qemu-img: /Applications/GNS3.app/Contents/Resources/Qemu-0.14.1/bin/qemu-img
Qemuwrapper port: 10525 TCP
Base console port: 3001 TCP
Base UDP port: 40000 UDP
IP/host binding: 127.0.0.1
External Qemuwrapper: localhost:10525
Registered external Qemuwrapper: localhost:10525
