Hi, I have installed Linux on RH 7.3 with iptables v 1.2.3 But when I try to connect to a Microsoft FTP Service (Version 5.0) it hangs up afrter, 220 erecording Microsoft FTP Service (Version 5.0). Name (208.253.196.145:root): administrator It does not prompt for password. What must be the problem? On some servers I it hangs when given ls command on remote hosts (Linux machine, proftpd servers). My lsmod gives, # lsmod Module Size Used by ipt_state 1152 4 (autoclean) ipt_MASQUERADE 1824 1 (autoclean) iptable_filter 2256 0 (autoclean) (unused) ip_nat_ftp 3680 0 (unused) ip_conntrack_ftp 4080 0 (unused) iptable_nat 18224 1 [ipt_MASQUERADE ip_nat_ftp] ip_conntrack 16944 3 [ipt_state ipt_MASQUERADE ip_nat_ftp ip_conntrack_ftp iptable_nat] ip_tables 11392 6 [ipt_state ipt_MASQUERADE iptable_filter iptable_nat] autofs 11520 0 (autoclean) (unused) 8139too 12832 1 eepro100 17664 1 usb-ohci 18544 0 (unused) usbcore 51712 1 [usb-ohci] ext3 64624 6 jbd 40992 6 [ext3] aic7xxx 114544 7 sd_mod 11584 7 scsi_mod 95664 2 [aic7xxx sd_mod] Thanks a lot and eagerly waiting for the reply.
