On web i have found several solutions how to get list of computers in
network on Windows platform, but none for Linux. BTW I've recently
switched from Win to Ubuntu ...

or perhaps on a plain vanilla Ubuntu:
Code: [Select]sudo apt-get install nmap
man nmap
... and you can parse e.g. the XML format it spits out.

Also:
Code: [Select]man ping
and probably
Code: [Select]man smbclient #not sure about name; perhaps you need to
install samba tools as well
depending on what OP wants exactly (e.g. is a computer something that
respods to ping? Has an ftp share open? Provides nfs? Smb?

Thanks for the reply ill try it out.
Aim of app is to be used in network (for daily business needs) and
when it starts user can picks a computer from a list - where current
and active database file is stored (firebird) and for that i needed
the list of network computers.

In that case, I'd first ping your subnet, then try to connect to the
firebird port (3050 TCP by default, IIRC) to see if something (e.g.
Firebird) is listening.

HOWEVER, why don't you just use a config file with the server IP
address/hostname? An admin will have to set up a Firebird server
anyway?

(firebird)
Note: FYI: if using Firebird for multiple users, you're supposed to
use a server, not a file share with an fdb file on it and e.g.
multiple embedded client. You may get data corruption, locking etc.
Just thought I'd mention it.

Just thought I'd mention it.well one machine has a firebird server
installed and other users have fbclient.dll in applications directory.
By picking up from the list server comp they connect to database on
that machine. This is done in case something happens to server so a
new server computer can easily replace it ( of course after installing
fb server on it). Is this ok ? or im still getting something wrong?
at least this is how i started it under windows

@alehandro, no, that's fine.
