Hi,
I've encountered a problem with a perl and ksh script that totals a certain field in a text file. The computed total of the script is 295540304 but the expected is 297959288, a 2 million difference. The KSH script reads from bottom to top, and the discrepancy started on line 47 (1279th MAN... (1 Reply)
Hi,
I am trying to get the cpu usage of a job/process. The machine that has these jobs is a cluster with 1 master node and 10 compute nodes.
Now, the complexity is that not all jobs are on the master node. So, in order to get the cpu usage of a job at another node, I have to ssh into it and... (0 Replies)

Guys, have any idea for the script like this? also to compute w/ decimal.
thanks
a=10
b=20
c=30
d=40
if a < b then ( a -b)*1024 = free space
b + (c -d) = total space
if a > b then (b / d)*1024 = cpu (3 Replies)

SHOREWALL-BLACKLIST(5) [FIXME: manual] SHOREWALL-BLACKLIST(5)NAME
blacklist - Shorewall Blacklist file
SYNOPSIS
/etc/shorewall/blacklist
DESCRIPTION
The blacklist file is used to perform static blacklisting. You can blacklist by source address (IP or MAC), or by application.
The columns in the file are as follows (where the column name is followed by a different name in parentheses, the different name is used in
the alternate specification syntax).
ADDRESS/SUBNET (networks) - {-|~mac-address|ip-address|address-range|+ipset}
Host address, network address, MAC address, IP address range (if your kernel and iptables contain iprange match support) or ipset name
prefaced by "+" (if your kernel supports ipset match). Exclusion (shorewall-exclusion[1](5)) is supported.
MAC addresses must be prefixed with "~" and use "-" as a separator.
Example: ~00-A0-C9-15-39-78
A dash ("-") in this column means that any source address will match. This is useful if you want to blacklist a particular application
using entries in the PROTOCOL and PORTS columns.
PROTOCOL (proto) - {-|[!]protocol-number|[!]protocol-name}
Optional - If specified, must be a protocol number or a protocol name from protocols(5).
PORTS - {-|[!]port-name-or-number[,port-name-or-number]...}
Optional - may only be specified if the protocol is TCP (6) or UDP (17). A comma-separated list of destination port numbers or service
names from services(5).
OPTIONS - {-|{dst|src|whitelist|audit}[,...]}
Optional - added in 4.4.12. If specified, indicates whether traffic from ADDRESS/SUBNET (src) or traffic to ADDRESS/SUBNET (dst) should
be blacklisted. The default is src. If the ADDRESS/SUBNET column is empty, then this column has no effect on the generated rule.
Note
In Shorewall 4.4.12, the keywords from and to were used in place of src and dst respectively. Blacklisting was still restricted to
traffic arriving on an interface that has the 'blacklist' option set. So to block traffic from your local network to an internet
host, you had to specify blacklist on your internal interface in shorewall-interfaces[2] (5).
Note
Beginning with Shorewall 4.4.13, entries are applied based on the blacklist setting in shorewall-zones[3](5):
1. 'blacklist' in the OPTIONS or IN_OPTIONS column. Traffic from this zone is passed against the entries in this file that have
the src option (specified or defaulted).
2. 'blacklist' in the OPTIONS or OUT_OPTIONS column. Traffic to this zone is passed against the entries in this file that have the
dst option.
In Shorewall 4.4.20, the whitelist option was added. When whitelist is specified, packets/connections that match the entry are not
matched against the remaining entries in the file.
The audit option was also added in 4.4.20 and causes packets matching the entry to be audited. The audit option may not be specified in
whitelist entries and require AUDIT_TARGET support in the kernel and iptables.
EXAMPLE
Example 1:
To block DNS queries from address 192.0.2.126:
#ADDRESS/SUBNET PROTOCOL PORT
192.0.2.126 udp 53
Example 2:
To block some of the nuisance applications:
#ADDRESS/SUBNET PROTOCOL PORT
- udp 1024:1033,1434
- tcp 57,1433,1434,2401,2745,3127,3306,3410,4899,5554,6101,8081,9898
