Script which telnets to a device, runs commands and prints output to a file
I am connecting to a device using telnet, I want my script to perform certain commands : ie- show device , show inventory..etc and write the output it sees from the terminal to a file.
this is what I have got :
So what is happening now is after the first loop it is printing the data of the result to master1.txt file...but after the execution it comes to:
master>
and stops.. I tried modifying the second loop to say:
expect "master>" send "exit\r"
just to see if it exits out but its not reading the command and not exiting, I have to manually exit out. Please help me on what I am doing wrong. This is my first time with "expect" so "expect-ing" to learn here
Thanks..
How could you put the output of two commands into one file using a single command? For example put the output of a grep command and a sort command into one file together.
Here is another rough explanation of what I am trying to do;
output of
$ grep pattern file1
plus output of
$ sort file... (8 Replies)

Hi all. On X11 I'm on a shell ...shell_1 (/bin/bash). From here I want to open another shell window shell_2 who executes commands like "ls -l" or programs like ". /program"... so the "result" of commands shows in shell_2 window and not in shell_1. Is that possible ? (4 Replies)
We had a system outage, and now I am trying to figure out how to get raw data to store in a log file.
I have a flat file that has multiple IP port line.
I want to telnet to each and log each.
But as soon as I connect to the first, it stays there.
This is on an HPUX 11.23 system. I dont think... (1 Reply)

Dear all,
I am using sed as an alternative to grep in order to get a specific line from each of multiple files located in the same directory. I am using sed because it prints the lines in the correct order (unlike grep).
When I write sed code that prints out the output I get it correct, but... (1 Reply)

conntrackd
CONNTRACKD(8)CONNTRACKD(8)NAME
conntrackd - netfilter connection tracking user-space daemon
SYNOPSIS
conntrackd [options]
DESCRIPTION
conntrackd is the user-space daemon for the netfilter connection tracking system. This daemon synchronizes connection tracking states
between several replica firewalls. Thus, conntrackd can be used to deploy highly available stateful firewalls. The daemon supports Primary-
Backup and Multiprimary setups. The daemon can also be used as statistics collector.
OPTIONS
The options recognized by conntrackd can be divided into several different groups.
MODES
These options specify the particular operation mode in which conntrackd runs. Only one of them can be specified at any given time.
-d Run conntrackd in daemon mode.
CLIENT COMMANDS
conntrackd can be used in client mode to request several information and operations to a running daemon
-i [ct|expect]"
Dump the internal cache, i.e. show local states
-e [ct|expect]"
Dump the external cache, i.e. show foreign states
-x Display output in XML format. This option is only valid in combination with "-i" and "-e" parameters.
-f [|internal|external]
Flush the internal and/or external cache
-F [ct|expect]
Flush the kernel conntrack table (if you use a Linux kernel >= 2.6.29, this option will not flush your internal and external cache).
-c Commit external cache to conntrack table.
-B Force a bulk send to other replica firewalls. With this command, you will ask conntrackd to send the state-entries that it owns to
others.
-n Request resync with other node (only FT-FW and NOTRACK modes).
-k Kill the daemon
-s [|network|cache|runtime|link|rsqueue|process|queue|ct|expect]
Dump statistics. If no parameter is passed, it displays the general statistics. If "network" is passed as parameter it displays the
networking statistics. If "cache" is passed as parameter, it shows the extended cache statistics. If "runtime" is passed as param-
eter, it shows the run-time statistics. If "process" is passed as parameter, it shows existing child processes (if any). If
"queue" is passed as parameter, it shows queue statistics. If "ct" is passed, it displays the general statistics. If "expect" is
passed as parameter, it shows expectation statistics.
-R [ct|expect]
Force a resync against the kernel connection tracking table
-t Reset the in-kernel timers (See PurgeTimeout clause)
-v Display version information.
-h Display help information.
-C config file
Configuration file path.
DIAGNOSTICS
The exit code is 0 for correct function. Errors cause an exit code of 1.
EXAMPLES
The following example are illustrative, for a real use in a firewall fail-over, check the primary-backup.sh script that comes with the
sources.
conntrackd -d
Runs conntrackd in daemon and synchronization mode
conntrackd -i
Dumps the states held in the internal cache, i.e. those handled by this firewall
conntrackd -e
Dumps the states held in the external cache, i.e. those handled by other replica firewalls
conntrackd -c
Commits the external cache into the kernel connection tracking system. This is used to inject the state so that the connections can
be recovered during the failover.
DEPENDENCIES
This daemon requires a Linux kernel version >= 2.6.18. TCP window tracking support requires >= 2.6.22, otherwise you have to disable it.
Helpers are fully supported since >= 2.6.25, however, if you use any previous version, depending on the protocol helper and your setup
(e.g. if you setup performs NAT sequence adjustments or not), your help connection may be successfully recovered.
There are several unsupported stateful iptables matches such as recent, connbytes and the quota matches which gather internal information
to operate. Since that information does not belong to the domain of the connection tracking system, connections affected by those matches
may not be fully recovered during the takeover.
The daemon requires a Linux kernel version >= 2.6.26 to support kernel-space event filtering. Otherwise, all the event filtering is done in
userspace with the corresponding extra overhead. If you are not using the Filter clause in the configuration file, ignore this notice.
INCOMPATIBILITIES
During the 0.9.9 development, some important changes in the replication message format were introduced. Therefore, conntrackd >= 0.9.9 will
not work appropriately with conntrackd <= 0.9.8. This should not be a problem if you use the same conntrackd version in all the firewall
replica nodes.
