I just wanted to know what's your opinion on my problem.I have few linux servers that can be located on any place in the world, only port 22 is open. At my office I need connection to every server, but every server must be isolated from every server.So by now I worked only with ssh authorization by username and password. What seems to be preferable ?.
1 Going on working with ssh with authorization.
2 working with ssh but with adding keys
3 start to work with vpn
So if I am keeping use ssh with authorization I need something that will change password every month only for security working with ssh key, it seems like key depends on gateway where key created so if change gateway I lost connection using vpn sounds good but in this case I mush isolate servers from each other.The best solution I think is combination of any two methods

I want to reinstall "system-config-network" in Fedora10. I have now system-config-network 1.5.95 and I want to have system-config-network 1.4.3 (it is from fedora8)
View 3 Replies View RelatedI've been running F10 since it first came out, and I was happy to see it was the first Fedora release that automatically recognized my Atheros wireless card. I have to run system-config-network and press the "activate" button when I start the machine, but that's ok and no big deal. But today, for whatever reason,in system-config-network, the "activate" and "deactivate" buttons are grayed out and I cannot start the device so I have no network access. When I boot the machine into Windows, it works fine.

i used to download files using transmission bit torrent client.

View 1 Replies View RelatedI am running Ubuntu 10.10, upgraded a few weeks ago from 10.04. I noted from the system monitor that the system was generating a lot of network traffic, on the order of 10Mbps if the information is correct (using system monitor and iftop). From the process table, it appears that smbd is accumulating a lot of CPU time, which sort of makes sense as I use Samba for printing from a Windows 7 laptop. But the traffic seems to be making a round trip as I just rebooted the system and it reports in about 10 minutes of uptime 1.2GB was send and 1.2GB was received. Laptop is used for work, it is sitting idle for the last 30 minutes (VPN connection, etc); no backup or other interaction with the Ubuntu system.

I was trying to set my wireless to start up when the computer is booted like the regular ethernet eth0 but I can't figure out how to set the WPA pass phrase with system-config-network
View 2 Replies View RelatedI've tried to configure :
- a wired network
- a wireless network
- a mobile broadband network as both "system connection" and "automatic connection".
I need to have a laptop that will try to connect as sson as I plug the ethernet cable in or as soon as it senses a certain SSID or as soon as there's a mobile broadband device plugged into a USB port. Non-system connections are working but I am not willing the actual user (non-admin) to read the WPA2 key or the SIM PIN. But the check box for the system connection is disabled. And running "sudo kcmshell4 --icon networkmanager kcm_networkmanagement kcm_networkmanagement_tray" doesn't result in a system connection.

My networkmanager understands that the card is installed. But it can not find any network. Also iwlist scan gives me no result. I did not have this problem on earlier fedora releases. Recently I upgraded to F12 from F11. I should mention that I have another USB DLink wireless card and when I plug it, everything works fine with that card. I also tested wl_apsta driver using fw-cutter. I did not work neither.
This may fall under the "ain't broke don't fix it" category but it's driving me nuts. I've got the Broadcom 4322 wireless adapter in my laptop and it works fine with broadcom-wl driver and kmod. However there is no ifcfg-eth1 file and the card does not show up in system-config-network.
