I was using pfSense in a vm under esx but I want to move to Xen and prefer something that can run as a pv guest. Anyone got any reco's of what can run on top of CentOS to perform a similar role as pfSense (perform nat/pat and firewall etc between two interfaces)? Thanks for any ideas! jlc

count of active tcp sockets?
by J Potter 18 Apr '08

18 Apr '08

Hi List, Is there an easy way to get a count of the number of active socket connections, or even better, number of socket connections in the time_wait state? (Something lightweight... under /proc/sys/net/ipv4/? I'd like to avoid the impact of listing out all the connections a-la netstat.) Thanks! -Jeff

CentOS 4.6 - dhcp issue
by Tom Brown 17 Apr '08

17 Apr '08

Hi - On my CentOS 4 cobbler server i am having some odd dhcp issues. There is only 1 dhcp server on the network and the cobbler box manages the dhcp. When i kick off the PXE install during the PXE phase things seem OK then when anaconda tried to get an IP sometimes things work out fine and other times it sits waiting for hostname/domainname. From the logs you can see that the mac requesting the IP is constant but the IP being offered is sometimes 'wrong'. In the 2 examples below nothing is changed the differing result is just achieved by trying another install, as i said its rather random. Any thoughts? thanks ** section of log i see when i have install issue ** Apr 16 14:25:53 cobbler dhcpd: DHCPDISCOVER from 00:0c:29:16:f8:b5 via eth0 Apr 16 14:25:53 cobbler dhcpd: DHCPOFFER on 192.168.12.190 to 00:0c:29:16:f8:b5 via eth0 Apr 16 14:25:53 cobbler dhcpd: DHCPDISCOVER from 00:0c:29:16:f8:b5 via eth0 Apr 16 14:25:53 cobbler dhcpd: DHCPOFFER on 192.168.12.190 to 00:0c:29:16:f8:b5 via eth0 Apr 16 14:25:53 cobbler dhcpd: DHCPREQUEST for 192.168.12.212 (192.168.12.117) from 00:0c:29:16:f8:b5 via eth0: lease 192.168.12.212 unavailable.

Edit to change startup from SMP to not so SMP
by Andrew ＠ ATM Logic 17 Apr '08

17 Apr '08

I have an issue on a server that stops to ask SMP or not so SMP on bootup. Its a pain as its a remote unit, and if I update (or the power goes out for 3 hours) the server will not restart.... I remember back in the day editing a start up file to tell it what kernel to start... Is that the file I am looking for to tell it to autostart smp??? Anyone have a 101 on how to do this? Thanks,
