Tim: >> send us the output from: >> chkconfig --list Arun: > [root@itqs-arun arun]# chkconfig --list > > bash: chkconfig: command not found I'm guessing that you became root by doing "su" rather than "su -", so the /sbin directory isn't in your search path. It's usually best to become root using "su -" rather than "su", then you'll get the full root user's working environment. Next time you get a "command not found" error, try using the locate command (e.g. locate chkconfig). If the drive's been indexed, you'll get a list of results, and if you see /sbin/ or /usr/sbin/ you can type the full path, or use a login that includes that path by default. NB: You can grep the output to ignore other non-command files with the same characters in the filenames (libraries, documentation, etc.). e.g. locate chkconfig|grep bin Otherwise, to use unfound commands, you can just try prefixing them with /sbin/ or /usr/sbin/. > I have listed the services > > Networkmanager – disable > Networkmanagerdispatcher – disable > > bluetooth – disable > iptables – disable netfs – running > netplugd – disable > > network – running > nfs – disable > nfslock – running > nscd – disable > > ntpd – disable > > As soon as I enable Networkmanager, Networkmanagerdispatcher, my > network Notwork. And in that list is what I mentioned earlier on in this thread - the "network" service and the "NetworkManager..." services are not compatible. You use network without the NetworkManager services, or you use the NetworkManager services without the network service. Trying to use them both at the same time is problematic. The "network" service starts up manually setup networks, or installation-time setup networks. It can handle static addresses, and doesn't need a DHCP server on the network. It can also handle dynamic addresses, and use DHCP, but it doesn't *need* them. What it's not good at handling is varying networks (e.g. wireless now, wired later, and swapping between them automatically). The "NetworkManager" and "NetworkManagerDispatcher" services can handle adhoc networks that change (going from wireless to wired, or from one wireless network to another), automatically. But it depends on there being automatic assignment of network addresses by something else, such as a DHCP server, or self-assigned automatic addresses using a zeroconf service running on the same machine. -- (This computer runs FC7, my others run FC4, FC5 & FC6, in case that's important to the thread.)
