somehow I managed to mess up my ip-tables config. I get this error when I try to restart iptables,


[root@tktdgt ~]# service iptables restart
: command not foundbles-config: line 7:
: command not foundbles-config: line 14:
: command not foundbles-config: line 20:
: command not foundbles-config: line 26:
: command not foundbles-config: line 33:
Flushing firewall rules:                                   [  OK  ]
Setting chains to policy ACCEPT: mangle filter             [  OK  ]
[root@tktdgt ~]#

My file is below, it looks fine to me.


# Load additional iptables modules (nat helpers)
#   Default: -none-
# Space separated list of nat helpers (e.g. 'ip_nat_ftp ip_nat_irc'), which
# are loaded after the firewall rules are applied. Options for the helpers are
# stored in /etc/modules.conf.
IPTABLES_MODULES=""
 
# Unload modules on restart and stop
#   Value: yes|no,  default: yes
# This option has to be 'yes' to get to a sane state for a firewall
# restart or stop. Only set to 'no' if there are problems unloading netfilter
# modules.
IPTABLES_MODULES_UNLOAD="no"
 
# Save current firewall rules on stop.
#   Value: yes|no,  default: no
# Saves all firewall rules to /etc/sysconfig/iptables if firewall gets stopped
# (e.g. on system shutdown).
IPTABLES_SAVE_ON_STOP="no"
 
# Save current firewall rules on restart.
#   Value: yes|no,  default: no
# Saves all firewall rules to /etc/sysconfig/iptables if firewall gets
# restarted.
IPTABLES_SAVE_ON_RESTART="no"
 
# Save (and restore) rule and chain counter.
#   Value: yes|no,  default: no
# Save counters for rules and chains to /etc/sysconfig/iptables if
# 'service iptables save' is called or on stop or restart if SAVE_ON_STOP or
# SAVE_ON_RESTART is enabled.
IPTABLES_SAVE_COUNTER="no"
 
# Numeric status output
#   Value: yes|no,  default: yes
# Print IP addresses and port numbers in numeric format in the status output.
IPTABLES_STATUS_NUMERIC="yes"

Did you edit the file in dos? If so, run

dos2unix -p /path/to/file

It seems its complaining about all the blank lines

Remove run execute only iptables -L

If seems that you're running over RedHAT / CentOS . The default configuration is in /etc/sysconfig/iptables

If the code sniipet belongs to this file it is normal that you have nothing because your file does not contain any rules for firewall.
