My Linux box (SuSE 7.1, X, harden_suse) did strange things this morning and I wonder if there are some likely explanations or if this could be an attack: - while opening a large mail (about 245 K) with the Netscape Mail Client, Netscape stopped responding to user input (window was not repainted as well) - I tried switching to an open X-Term, but was not able to move the focus to that window - Switched to another console, logged in and tried killing the netscape process -> console ceased accepting input - Logged in remotely via ssh, which at first worked, but behaved weirdly (keystrokes were not displayed until the next key pressed) - then ssh ceased accepting input as well - switched the box off (Painful) and rebooted and everything worked - checked the log files (also firewall logs - I am behind a corporate FW), but could not find anything While this might not be a security related problem I'd appreciate any hints/tips/advice from the experts here. Thank you, .ps
