GNS3 1.0 Alpha 4!

GNS3 1.0 Alpha 4 is out today, coming in a week or so before the next bank holiday in the UK. I am sure that the bank holiday releases are just a coincidence unless the developers are really keen on celebrating the “International Day of Families” (yeah I don’t know what it’s about either – alternatively it could be released in celebration of Paraguay’s Independence Day).

So anyway, enough about random world wide holiday talk, let’s have a look at what’s new (and fixed):

Whats new in GNS3 1.0 Alpha 4?

Now we have the following changes:

  • Show Windows interface names in cloud tooltips.
  • Disconnect the server if the version differs from the GUI version.
  • Move cloud code to a builtin module and support for clouds on remote servers.
  • Options to use the default IOU RAM & NVRAM values.
  • Changed the name of default base startup and private configs.
  • Added “All files” filter when looking for an IOU or IOS image in the file browser.
  • Graceful server shutdown on Windows.
  • Error message that JIT sharing is only supported in Dynamips unstable.
  • New UDP and console port allocation system for IOU. Fixes duplicated port issues.
  • Delete some Dynamips files that are useless to save in projects.
  • Fix: the path to GNS3 server was not saved.
  • Fix: RAM and NVRAM IOU image settings not propagated when creating an IOU device.
  • Fix: bug where IOS nvram/disk files were not kept after closing a topology.
  • Fix: bug that prevented changing any IOU device setting when connected to another node.
  • Fix: duplicated node id issue.
  • Fix: major bug with ghost instance overwriting any second router files (R2).
  • Fix: error when ldd cannot be found.
  • Fix: issues with local base configs for IOS.

Some pretty cool stuff here, especially the third item – “support for clouds on remote servers”, this isn’t to say that we can have multiple IOU servers sitting out there, it’s close, very close, but not there just yet:

Multiple IOU servers in GNS3

So close!

Still no sign of the ability to add text to topologies though. I do miss that.
