Navigation, pop and smtp frozen
I'm a new linux enthusiast and I have installed a Mandriva LE 2005.
Recently I have updated successfully both Firefox, Opera and Open Office to their latest releases; but since some days I experience problems during navigation and during sending/receiving mails. I remark I make use of Opera as predefined browser and mail client.
I suspect there is a process that starts randomly and jams such communications (firefox suffers of navigation jams too) but I'm not able to detect it using ps or netstat.
More precisely, I don't know very well where and how to look...
Can you suggest me a more powerful strategy to keep a strong surveillance on processes that uses network connections?
Thank you in advance for your kindest reply.
