Recently I downloaded some kernel*.rpm (Linux i386) from https://rhn.redhat.com/errata/RHSA-2003-417.html and I installed all the rpms using "rpm -iUvh kernel*.rpm". My mistake. I should have used "rpm - Fvh". Now I do not know what kernel was there previously. From the following output it looks, I had 2.4.20-18.9smp earlier. % ls -l /lib/modules/ total 12 drwxr-xr-x 3 root root 4096 Jan 6 15:03 2.4.20-18.9smp drwxr-xr-x 3 root root 4096 Jan 12 16:01 2.4.20-28.9 drwxr-xr-x 3 root root 4096 Jan 6 15:02 2.4.20-28.9BOOT % rpm -qa | grep kernel kernel-pcmcia-cs-3.1.31-13 kernel-2.4.20-28.9 kernel-BOOT-2.4.20-28.9 kernel-doc-2.4.20-28.9 kernel-source-2.4.20-28.9 Now, whenever I boot the system it comes up with "2.4.20-28.9BOOT" which doesn't have iptables module. % lsmod Password: Module Size Used by Not tainted e1000 54528 1 ext3 61280 2 jbd 46804 2 [ext3] 3w-xxxx 36192 3 sd_mod 11916 6 scsi_mod 63416 2 [3w-xxxx sd_mod] % uname -a Linux dev9.my-comp.com 2.4.20-28.9BOOT #1 Thu Dec 18 13:27:13 EST 2003 i686 i686 i386 GNU/Linux I have ip tables in 2.4.20-28.9 % ls -l /lib/modules/2.4.20-28.9/kernel/net/ total 68 drwxr-xr-x 2 root root 4096 Jan 6 15:02 8021q drwxr-xr-x 2 root root 4096 Jan 6 15:02 appletalk drwxr-xr-x 2 root root 4096 Jan 6 15:02 atm drwxr-xr-x 2 root root 4096 Jan 6 15:02 ax25 drwxr-xr-x 4 root root 4096 Jan 6 15:02 bluetooth drwxr-xr-x 2 root root 4096 Jan 6 15:02 bridge drwxr-xr-x 2 root root 4096 Jan 6 15:02 decnet drwxr-xr-x 3 root root 4096 Jan 6 15:02 ipv4 drwxr-xr-x 3 root root 4096 Jan 6 15:02 ipv6 drwxr-xr-x 2 root root 4096 Jan 6 15:02 ipx drwxr-xr-x 5 root root 4096 Jan 6 15:02 irda drwxr-xr-x 2 root root 4096 Jan 6 15:02 netrom drwxr-xr-x 2 root root 4096 Jan 6 15:02 rose drwxr-xr-x 2 root root 4096 Jan 6 15:02 sched drwxr-xr-x 2 root root 4096 Jan 6 15:02 sunrpc drwxr-xr-x 2 root root 4096 Jan 6 15:02 tux drwxr-xr-x 2 root root 4096 Jan 6 15:02 wanrouter /lib/modules/2.4.20-28.9/kernel/net/ipv4/netfilter/ip_tables.o But not under 2.4.20-28.9BOOT/ (there is no ipv?) % ls -l /lib/modules/2.4.20-28.9BOOT/kernel/net/ total 24 drwxr-xr-x 2 root root 4096 Jan 6 15:02 8021q drwxr-xr-x 2 root root 4096 Jan 6 15:02 ax25 drwxr-xr-x 4 root root 4096 Jan 6 15:02 bluetooth drwxr-xr-x 2 root root 4096 Jan 6 15:02 netrom drwxr-xr-x 2 root root 4096 Jan 6 15:02 rose drwxr-xr-x 2 root root 4096 Jan 6 15:02 sunrpc Now, I only have remote access to this server and I don't have access to the console at this time. Is there a way, I can boot the system with "2.4.20-28.9" instead of "2.4.20- 28.9BOOT". If the system does not come up properly, I should be able to reboot with "2.4.20-28.9BOOT" which is working (but no iptables). I have only remote power cycle capability. Could you please suggest a way to get this done? Note: This is follow-up to the question I earlier posted on "iptables v1.2.7a: can't initialize iptables table `filter':" thanks, Prince.
