Troubleshooting HP-UX IPSec

Troubleshooting Scenarios

Symptoms

The administrator cannot get a certificate using ipsec_mgr. ipsec_mgr shows no certificate entry or an incomplete entry. The audit file shows the following error: Unable to obtain public/private key pair!

Solution

Check stdout for ipsec_mgr errors. Check the VeriSign Managed PKI Control Center for a pending request or existing certificate. Check the web proxy configuration (run ipsec_mgr, click on the Options menu, select System, then select Proxy Information). You may need to reset /var/adm/ipsec/cainfo.txt; remove /var/adm/ipsec/javabeans.txt, /var/adm/ipsec/certs.txt; revoke the old certificate, and restart the registration procedure.

Details

If you cannot get a VeriSign certificate or if you forget to retrieve the certificate after you request it, ipsec_mgr may show a certificate entry for the local system. However, if you click Details the entry will be incomplete (there will be no information other than the IP address). When you attempt to initiate an ISAKMP/MM SA, it will fail and you will see errors similar to the following in the log file:

Msg: 201 From: IKMPD Lvl: ERROR Date: Mon Mar 11 16:19:39 2002 Event: Unable to obtain public/private key pair!

Msg: 202 From: IKMPD Lvl: ERROR Date Mon Mar 11 16:19:39 2002 Event: Process contruct error 0x1

Msg: 203 From IKMPD Lvl: ERROR Date Mon Mar 11 16:19:39 2002 Event: Main Mode processing failed

If ipsec_mgr has problems retrieving a VeriSign certificate, it will write errors to the stdout device for ipsec_mgr (the device from which ipsec_mgr was started). The ipsec_mgr does not log errors using the HP-UX IPSec daemon.

If you request a VeriSign certificate using ipsec_mgr and ipsec_mgr cannot retrieve the certificate (the Check on Request operation fails), it is possible that the Managed PKI Administrator has not yet approved your certificate request. Have the Managed PKI Administrator use the VeriSign Managed PKI Control Center to check for pending requests. If the Managed PKI Administrator did not receive a request for approval, verify communication with the Managed PKI Control Center. If you are

UX IPSec Software specifications

HP-UX IPSec Software is an integral component of the HP-UX operating system, providing robust and secure communication capabilities for enterprise environments. As organizations increasingly rely on secure networking solutions, HP-UX IPSec stands out with its comprehensive set of features and technologies designed to safeguard sensitive data.

One of the core characteristics of HP-UX IPSec Software is its implementation of the Internet Protocol Security (IPSec) framework. This technology secures Internet Protocol (IP) communications through authentication and encryption, ensuring the integrity and confidentiality of data transmissions. By leveraging IPSec, HP-UX provides a secure method for connecting remote users and secure sites over untrusted networks, such as the internet.

A notable feature of the HP-UX IPSec Software is its support for both transport and tunnel modes. The transport mode encrypts only the payload of the IP packet, whereas the tunnel mode encapsulates the entire IP packet within a new packet, allowing for secure communications between entire networks. This flexibility enables organizations to tailor their security strategies based on specific use cases and requirements.

HP-UX IPSec also emphasizes interoperability and compliance with industry standards. The software supports various encryption algorithms and authentication methods, including those defined by the Internet Engineering Task Force (IETF). This commitment to open standards ensures that HP-UX can seamlessly integrate with a diverse range of networking infrastructures and security solutions.

In addition to its security features, HP-UX IPSec Software offers administration tools that simplify the configuration and management of IPSec policies. The software includes a user-friendly command-line interface, allowing system administrators to specify security associations and policies efficiently. Moreover, comprehensive logging and monitoring capabilities help organizations keep track of their security posture and detect potential vulnerabilities.

Another essential characteristic of HP-UX IPSec Software is its scalability. Designed to accommodate the needs of both small and large enterprises, it can handle increased loads and adapt to changing security demands without compromising performance.

In conclusion, HP-UX IPSec Software stands as a vital solution for organizations seeking to protect their data transmissions over IP networks. With its core technologies, such as transport and tunnel modes, adherence to industry standards, user-friendly administration tools, and scalability, it provides a formidable layer of security in an increasingly interconnected world. This makes it a preferred choice for enterprises aiming to enhance their network security frameworks.
