Goodday everyone, I have a strange problem, I'll like someone to help me out. I'm running RedHat-7.2 on i686 Pentium II. This server alone is running sendmail, dns and squid proxy server. I have two interfaces and I use Ipchains to do the firewalling. The cache dir for squid is mounted on /cache and I didn't provide for log files.(i.e access_log /dev/null) etc. It ran for some days and one morning I can't log in and I saw a strange message as follows: "<1> Unable to handle kernel NULL pointer dereference at virtual address 00000004 Printing eip: C322d7be: *pde = 0000000 Oops: 0000 CPU:0 EIP:0010......... EFLAGS : 00000010 bla bla process sh : ---- bla bla stack:----- Call Trace : ------ code : 8b 42 04 ..........." Plse note that my server working properly. Sendmail, http, squid etc. But I can't login. When I put my login as root, it doesn't ask for the password. I'm affraid to reboot. Please help me.
