Hi.

Another admin type question: I am trying to access my running Virgo kernel via telnet. Although the connection succeeds and I get the osgi> prompt, I do no seem to be able to run any useful commands.

Any vsh command returns exception

gogo: CommandNotFoundException: Command not found: vsh

and any standard OSGi command (such as list etc.) return a "No repository admin service available" response, even though bundle com.springsource.server.management.remote is active.

Any help?

TIA,
B.

Hi,

Which version of Virgo Kernel do you use? 3.5.0.M02 - the latest development build, or 3.0.2 - the latest released version?

Regards,
Lazar

Sorry, I should have mentioned that. I am using 3.0.0.RELEASE (running a little behind)

In this version you should use vsh with prefix "equinox:". The same is valid for the list command. The console in RELEASE 3.0.0 uses the Gogo shell, which uses the notion of scopes - this is the prefix before the column. You may have commands with the same name but different scopes - this is the case with the list command.
As for the vsh command - you most probably call it in the shell to the kernel region. It is not present there - it is in the user region and you should open a connection to the shell in the user region and call the command there.

One more detail - you can see the list of all available commands using the command "equinox:help -all" or "man -all.

Thank you very much!

Using the "equinox:" prefix handles my problems.

Cheerio,
B.

Hey folks -- I am having the same issue (using jetty server 3.0.2-RELEASE), but both vsh and equinox:vsh both show the:
gogo: CommandNotFoundException: Command not found: equinox:vsh

I am telnet'd in to localhost, and I have:
osgi.console=2401
set in the org.eclipse.virgo.kern.userregion.properties.
Am I missing something?

Hi James.

I sometimes find I have to issue my command twice, the first time it fails with the error you mention and the second time it works. Weird and time consuming, but when you need the information... Smile

HTH,
B.

Thanks Barbara -- I tried a few times in a row, and nothing.
There is nothing for vsh or equinox:vsh in the help, the commands don't work -- just seems to not be there.

I tried the TOMCAT version (I'm using the jetty release normally) thinking that perhaps the vsh stuff wasn't installed with jetty, but no luck.
