- Fix the display of TN Redirector connections to properly show the partner client and partner host association.

7.0.0.3 enhancements:
- New Config panels providing SNA resource configuration for Device and Ports, Connections, Host Resources, TN3270E Server and APPC resources.
- Configuration operations provide the "snaadmin" command line operation issued for reference.

The WebAdmin Package provides 2 levels of access, WebAdmin, which allows read/write access for starting/stopping Node, Links, PUs and diagnostic traces. And Query access, which provides read-only access to the SNA resources. The supplied "installibmcsweb" script will perform most of the installation steps required. It prompts for which level of access to install on the local server.

- Capabilities

The Communications Server for Linux Web Admin  version provides two methods to access the Web displays presented by the Web Admin or the Query Admin paths for this package. The Web Admin gives access to administrators that allow the SNA server processes, links, and PUs to be managed. It also provides new functionality by providing Config panels to define SNA resources.

The Query Admin provides very similar paths to the query and status functions, but only allows Read access. You can direct administrators to access the Web Admin path, and more general audiences to access the Query Admin path.

This package also provides an install script that directs the installation and assists in configuration of the Web Admin, Query Admin or both access methods. The Web Admin package supports Apache 2.2 and Apache 2.4 levels (both are shipped with the RedHat, SuSE  and Ubuntu Enterprise Linux server distributions).

Using a Web server, like Apache, this package provides remote access to the administration functions such as query, status, start and stop which you normally find on the Motif-based xsnaadmin GUI. This package is particularly useful in providing the Linux on IBM Z user with a secure and safe method for remote administration of the Communications Server on Linux resources. This package will run on Intel x86_64, Power Linux ppc64le and IBM Z s390x platforms which are supported by the Communication Server for Data Center Deployment 7.1.

This package uses Perl-CGI and Perl scripts to execute the administration functions. Almost all Web browsers work well with this package. There are no browser dependencies for Java as in other Web Administration packages. Web browser Netscape V4.7 and prior releases do not work with this package. This package is English only.

The functions provide access to resources controlled in Node and Domain, Connections, Host Resources, TN3270E Server, APPC, APPN, Domain, Query, Status and Diagnostic panels. With these Web interfaces, you can query any resource on the node or get status of sessions, links, LUs and node conditions.

The Web Admin pages provide the interfaces to display link, PU and node conditions. You can start or stop the node, links and PUs as needed.  There is a Diagnostic menu that allows display of the Audit log, Error log and Usage log files. Traces can also be enabled through this menu. The Web Admin interface also provide configuration panels to allow SNA resources to be configured. The Query Admin pages provide only displays of these resources.

Remote access is protected by User ID and password authentication configured by the administrator. The install script will place the default configuration files into the appropriate configuration directories for Apache, depending on Apache level. Configuration requires additions to the sudoers configuration file , /etc/sudoers , and optionally updating the web server main pages to link to the CS Linux Web Administration package. This package requires the use of "visudo" to configure the access using a "snauser" level of access. Follow the README instructions to perform the configuration.
