I found character missing in this code. Working version is:
I would ask for your system administrator to run this code. After he does that, in /var/adm/ssh_logins lines like that will appear when someone executes ssh command:
On the right side of the file you will find uid of the user that executed ssh command (red) and where he wanted to connect (blue). You can then grep account/host information from that file. I hope this explanation makes it clearer...
Hi. I would like to be able to deny IP address for too many failed login attemps (either from ssh, sftp, ftp, etc). The system I wish this to work on is an AIX 5.1 system. I'm new to AIX but I'm a linux user. There is a program for linux called fail2ban which reads from the log files and see if... (1 Reply)
Hi,
I have created the below ftp script to put files over to our capacity server, the check at the end works if ftp fails to run however if the script cannot login or the transfer itself failed there is no warnings.

Hi,
I have a linux redhat 9 server and I am concerned about the security on that server.
I would like to be able to write a script that records all the commands that were typed at the command prompt before the user calls the 'history -c' command and deletes all the history.

Dear experts,
I am seeing a lot of TCP failed connection attempts from "netstat -s" on one of our servers.
How can I pin point what connection failed and what are the ports involved?
Any tools/commands I can dig in deeper to diag. what went wrong on these "failed connection attempts"?

The purpose of this thread is for everyone to follow the same methodology so we can create a future table, for the benefit of all, that shows how many failed login attempts (hacking) per day per server (and per minute) are happening.

ssh-socks5-proxy-connect
ssh-socks5-proxy-connect(1) User Commands ssh-socks5-proxy-connect(1)NAME
ssh-socks5-proxy-connect - Secure Shell proxy for SOCKS5
SYNOPSIS
/usr/lib/ssh/ssh-socks5-proxy-connect [-h socks5_proxy_host] [-p socks5_proxy_port] connect_host connect_port
DESCRIPTION
A proxy command for ssh(1) that uses SOCKS5 (RFC 1928). Typical use is where connections external to a network are only allowed via a socks
gateway server.
This proxy command does not provide any of the SOCKS5 authentication mechanisms defined in RFC 1928. Only anonymous connections are possi-
ble.
OPTIONS
The following options are supported:
-h socks5_proxy_host Specifies the proxy web server through which to connect. Overrides the SOCKS5_SERVER environment variable.
-p socks5_proxy_port Specifies the port on which the proxy web server runs. If not specified, port 80 is assumed. Overrides the
SOCKS5_PORT environment variable.
OPERANDS
The following operands are supported:
socks5_proxy_host The host name or IP address (IPv4 or IPv6) of the proxy.
socks5_proxy_port The numeric port number to connect to on socks5_proxy_host.
connect_host The name of the remote host to which the socks gateway is to connect you.
connect_port The numeric port number of the socks gateway to connect you to on connect_host.
EXAMPLES
The recommended way to use a proxy connection command is to configure the ProxyCommand in ssh_config(4) (see Example 1 and Example 2).
Example 3 shows how the proxy command can be specified on the command line when running ssh(1).
Example 1: Setting the proxy from the environment
The following example uses ssh-socks5-proxy-connect in ssh_config(4) when the proxy is set from the environment:
Host playtime.foo.com
ProxyCommand /usr/lib/ssh/ssh-socks5-proxy-connect
playtime.foo.com 22
Example 2: Overriding proxy environment variables
The following example uses ssh-socks5-proxy-connect in ssh_config(4) to override (or if not set) proxy environment variables:
Host playtime.foo.com
ProxyCommand /usr/lib/ssh/ssh-socks5-proxy-connect -h socks-gw
-p 1080 playtime.foo.com 22
Example 3: Using the command line
The following example uses ssh-socks5-proxy-connect from the ssh(1) command line:
example$ ssh -o'ProxyCommand=/usr/lib/ssh/ssh-socks5-proxy-connect
-h socks-gw -p 1080 playtime.foo.com 22' playtime.foo.com
ENVIRONMENT VARIABLES
SOCKS5_SERVER Takes socks5_proxy_host operand to specify the default proxy host.
SOCKS5_PORT Takes socks5_proxy_port operand to specify the default proxy port.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
