Hi, This problem may be related with the NAT rules for the firewall. Even if you don't have any NAT, the bdii service uses (I'm not expert in the inners of the bdii service) some that are started by the bdii service. I had the same problem, and what I did, and worked for me is: Stop the bdii service /etc/init.d/bdii stop Flush the NAT rules imposed by the service itself iptables -F -t nat Restart the service /etc/init.d/bdii start Hope it works Dani On Mon, 8 Aug 2005, Maarten Litmaath, CERN wrote: > On Mon, 8 Aug 2005, Sajjad Asghar wrote: > >> Hi >> >> Hi >> >> Iptables -L has returned following out put >> ------------------------------------------------------------------------ >> [root@pcncp04 root]# iptables -L >> Chain INPUT (policy ACCEPT) >> target prot opt source destination >> >> Chain FORWARD (policy ACCEPT) >> target prot opt source destination >> >> Chain OUTPUT (policy ACCEPT) >> target prot opt source destination >> >> ------------------------------------------------------------------------ >> ---- >> >> While the out put returned by iptables -L -t nat is as >> ------------------------------------------------------------------------ >> ---- >> Chain PREROUTING (policy ACCEPT) >> target prot opt source destination >> >> Chain POSTROUTING (policy ACCEPT) >> target prot opt source destination >> >> Chain OUTPUT (policy ACCEPT) >> target prot opt source destination >> ------------------------------------------------------------------------ >> ---- >> >> Rebooting of machine also has not worked. >> I also have tried to scan the ports with nmap e.g. >> Scanning of port 2170 and 2135 has returned following >> >> ------------------------------------------------------------------------ >> ---- >> [root@pcncp04 root]# nmap pcncp04.ncp.edu.pk -p 2170 >> >> Starting nmap V. 3.00 ( www.insecure.org/nmap/ ) >> Interesting ports on pcncp04.ncp.edu.pk (127.0.0.1): >> Port State Service >> 2170/tcp open unknown >> >> Nmap run completed -- 1 IP address (1 host up) scanned in 1 second >> ------------------------------------------------------------------------ >> ---- >> But same command is returning different result when running it from a >> Different host on the same network >> >> ------------------------------------------------------------------------ >> ---- >> [root@pcncp22 root]# nmap pcncp04.ncp.edu.pk -p 2170 >> >> Starting nmap V. 2.54BETA31 ( www.insecure.org/nmap/ ) >> The 1 scanned port on pcncp04.ncp.edu.pk (210.56.13.114) is: closed >> >> Nmap run completed -- 1 IP address (1 host up) scanned in 0 seconds >> ------------------------------------------------------------------------ >> ---- >> >> I have turned off all firewall services but still it is not working. >> Any idea how to solve this problem > > Another idea, though I do not see how it would explain your observations, > is to add the following to /etc/hosts.allow: > > slapd : 127.0.0.1 >
