-l, –log Log information for the matching packet (Web server)
-l, –log Log information for the matching packet to the system log. -t andmask xormask, –TOS andmask xormask Change the Type of Service field in the packet’s header. The TOS field is first ANDed with the 8-bit hexadecimal mask andmask, then XORed with the 8-bit hexadecimal mask xormask. Rules that would affect the least significant bit (LSB) portion of the TOS field are rejected. -x, –exact Expand all numbers in a listing (-L). Display the exact value of the packet and byte counters instead of rounded figures. [!] -y, –syn Match only incoming TCP connection requests, those with the SYN bit set and the ACK and FIN bits cleared. This blocks incoming TCP connections but leaves outgoing connections unaffected. –line-numbers Used with the -L command. Add the line number to the beginning of each rule in a listing indicating its position in the chain. –no-warnings Disable all warnings Return to: Alphabetical Directory of Linux Commands Copyright 2000-2002 O’Reilly & Associates, Inc.
