I think that I have solved the miracle of the starnge localhost: I have given the sme server the name "gateway" but the local gateway ist that router at 192.168.178.2. Although I've changed the name of SME this morning the entry for that local host is still in de shell- output.

Where? I have that Sme7admin but I can't find the actual IP-adresses with its windows names in there like here:

Doh! I use sme7admin on several hosts -- but I'm not using any of them for dhcp so I never noticed!

I get the folowing error:

Code: [Select]

Not quite ... it displays host name as eg: pc-00249.tibors.net ... it does not give you the pc name.

If SME7admin displayed the PC name as well it would be complete in my book.

I requested the creator to put that in when it was first made but nothing happened.

bpivk:

Make sure your 'test.sh' hasn't acquired any spaces after the various backslashes in the script...  the backslash is used to "escape" the <newline>, but if there's a space after it then it escapes that, instead, and breaks the command...

[bpivk]

Well i did a copy & paste in windows and linux twice and i had the same problem. But i won't give up.

bpivk, I had the same problem.  Pasting puts an extra space at the end of the line.  Open the file with pico or other editor and go to the end of each line with a / and delete any spaces after the / and save the file.  

It should work fine after that at least it did for me.

[mmccarn]

I have double-checked the post with the script on page one and don't see any extraneous spaces in the post itself; I don't know why they're showing up when you copy/paste the script into pico...

[bpivk]

Yes the problem was in the empty spaces in pico. I had to go from line to line and delete them. It works now.

Thanks

[CharlieBrady]

OK - I've updated the earlier script again.

Mike (I think) could you please post your code into a New Feature Request in the bug tracker. It'll just get lost here.

[mmccarn]

New Feature Request created: http://bugs.contribs.org/show_bug.cgi?id=2641

Script can be downloaded from: http://bugs.contribs.org/attachment.cgi?id=947

Or, download directly to your SME server using:
wget -O dhcpactiv.sh http://bugs.contribs.org/attachment.cgi?id=947

[calisun]

install sme7admin contrib, it gives you the information you need plus a lot more.

One more question:

how can I influence the work of the DHCP-Server? It would be nice if a certain MAC address would get always the same IP from the DHCP server.
