1. RHEL LIGHTSPEED 소개
RHEL Lightspeed를 지원하는 명령줄 도우미를 사용하면 명령줄에서 RHEL을 직접 관리할 수 있는 전
문적인 조언과 지원을 받을 수 있습니다. 도우미를 지원하는 AI를 통해 RHEL 제품 문서 및 Red Hat 지
식 베이스의 정보를 통합하고 RHEL 시스템을 이해, 구성 및 문제 해결에 도움이 될 수 있습니다.
> RHEL LIGHTSPEED를 지원하는 명령줄 지원 지원
RHEL Lightspeed를 지원하는 명령줄 도우미는 RHEL 명령줄 인터페이스 내에서 사용할 수 있는 선택적
AI 툴로, 다른 Red Hat 리소스 중 RHEL 설명서의 지식 센터 서비스(KCS) 문서의 Red Hat 지식에 대한 정
보가 포함됩니다. 도우미를 사용하여 다른 작업을 포함하여 다음 활동에 대한 도움을 받을 수 있습니다.
. RHEL 관련 질문에 응답
. 문제 해결 및 수정 지원
. 로그 파일 이해
. 권장 사항 요청
RHEL Lightspeed를 통해 대화형 워크플로우에 제공되는 명령줄 도우미를 사용하여 문제를 해결하고, 새
로운 RHEL 기능을 구현하며, 정보를 찾을 수 있습니다. 예를 들어 명령을 실행한 다음 명령줄 도우미를 사
용하여 출력 및 가능한 다음 단계를 이해할 수 있습니다. 또는 SSH에 질문을 하고 제안 사항을 받고, 문제
를 계속 진단하기 위해 다른 질문을 할 수 있습니다.
표준 명령줄 인터페이스를 사용하는 경우 복잡한 명령을 사용하는 대신 일반 언어를 사용하여 RHEL
Lightspeed를 지원하는 명령줄 도우미와 상호 작용할 수 있습니다.
RHEL Lightspeed를 지원하는 명령줄 도우미에는 직접 인터넷 연결이 필요하지 않습니다. 이는 인터넷을
통해 모든 RHEL 시스템을 직접 서비스에 연결하지 않으려면 인터넷에 연결된 단일 프록시 시스템을 통해
RHEL 시스템의 모든 요청을 프록시할 수 있는 경우에 유용합니다.

RHEL Lightspeed 사용genrative AI 기능
RHEL Lightspeed는 CryostatX AI API Cryostat(Large Language Model)를 사용합니다. 이 모델은 SaaS
외부 인프라로 배포됩니다. AI-command-line Assistant를 지원하는 Cryostat 모델은 IBM CryostatX AI 플
랫폼에서 호스팅되며 IBM CryostatX Cryostat IBM® Granite™ 모델을 사용합니다.

2. 1. RHEL LIGHTSPEED 사용
1) [root@test ~]# c "how to change hostname"
⁺₊+ Asking RHEL Lightspeed <------------이때 인터넷으로 연결해서 검색
────────────────────────────────────────────────────────────────────────
To change the hostname on a Red Hat Enterprise Linux (RHEL) system, you can use either the nmcli utility or the hostnamectl utility. Here, I'll provide instructions for both methods:
Using nmcli
··············
1. Display the current hostname setting:
``
nmcli general hostname
`
This command will show the current hostname, which in your case is old-hostname.example.com.
2. Set the new hostname:
`
nmcli general hostname new-hostname.example.com
`
3. Reboot the host for the changes to take effect:
`
reboot
`
Alternatively, if you know which services use the hostname, you can restart those services:
1. Restart all services that only read the hostname when the service starts:
`
systemctl restart _service_name_
``
2. Active shell users must re-login for the changes to take effect.
Using hostnamectl
····················
1. Optional: Display the current hostname setting:
``
hostnamectl status --static
`
This command will show the current static hostname, which in your case is old-hostname.example.com.
2. Set the new hostname:
`
hostnamectl set-hostname new-hostname.example.com
`
This command sets the static, pretty, and transient hostname to the new value. To set only a specific type, pass the --static, --pretty, or --transient option to the command.
3. Reboot the host for the changes to take effect:
`
reboot
`
Alternatively, if you know which services use the hostname, you can restart those services as mentioned in the nmcli` method.
Verification
·············
To verify the new hostname:
Snippet ────────────────
nmcli general hostname
────────────────────────
or
Snippet ────────────────
hostnamectl status --static
────────────────────────
Both commands should return new-hostname.example.com.

────────────────────────────────────────────────────────────────────────
I'm sorry to hear that you're encountering an issue with xrdp. The error message xrdp[123410]: [ERROR] SSL_accept: I/O error typically indicates a problem with the SSL/TLS connection, which is used for secure communication in xrdp.
Here are some steps you can take to troubleshoot this issue:
1. Check xrdp service status: Ensure that the xrdp service is running. You can do this by using the following command:
``
sudo systemctl status xrdp
`
If the service is not running, start it with:
`
sudo systemctl start xrdp
`
2. Review xrdp configuration: The main configuration file for xrdp is /etc/xrdp/xrdp.ini. Ensure that the settings related to SSL/TLS are correctly configured. Pay special attention to the [ssl] section.
3. Check firewall settings: Ensure that the necessary ports for xrdp are open in your firewall. By default, xrdp uses ports 3389 (RDP) and 3390 (xrdp). You can check and modify firewall rules with the firewall-cmd command:
`
sudo firewall-cmd --list-all
sudo firewall-cmd --add-port=3389/tcp --permanent
sudo firewall-cmd --add-port=3390/tcp --permanent
sudo firewall-cmd --reload
`
4. Update xrdp: If you're using an older version of xrdp, consider updating to the latest version available in the EPEL repository. You can update xrdp with the following commands:
`
sudo yum update xrdp -y
`
5. Check system logs: The system logs can provide more detailed information about the error. You can check the logs with the following command:
`
sudo journalctl -u xrdp -xe
``
Remember, since xrdp is not a supported solution by Red Hat, some of these steps might require additional troubleshooting or manual configuration. If you continue to experience issues, you might want to consider using a supported remote desktop method like VNC for RHEL.
For more detailed guidance, you can refer to the official Red Hat documentation or seek assistance from the xrdp community.

[root@test ~]# c "how to fix that pmlogger.service: Failed with result 'protocol'"
⁺₊+ Asking RHEL Lightspeed
────────────────────────────────────────────────────────────────────────
To address the issue with pmlogger.service failing with the result 'protocol', follow these steps:
1. Check the service status: First, verify the current status of the pmlogger service. You can do this by running:
``
systemctl status pmlogger
`
This command will provide you with detailed information about the service, including any error messages.
2. Review the logs: If the service is not running, check the logs for more details. The logs are usually located in /var/log/pmlogger/. Look for any error messages related to 'protocol'.
3. Ensure PCP is installed: The Performance Co-Pilot (PCP) is required for pmlogger to function correctly. Verify that PCP is installed on your system by running:
`
rpm -q pcp
`
If PCP is not installed, you can install it using:
`
sudo yum install pcp
`
4. Configure pmlogger: Ensure that the pmlogger configuration file is set up correctly. The configuration file is typically located at /etc/pcp-conf.d/pmlogger/config.pmlogger. Check for any syntax errors or incorrect settings.
5. Restart the services: After verifying the configuration, restart the pmcd and pmlogger services:
`
sudo systemctl restart pmcd pmlogger
`
6. Enable the services: To ensure that the services start automatically on boot, enable them:
`
sudo systemctl enable pmcd pmlogger
`
7. Check the service status again: After enabling and restarting the services, check their status again to confirm that they are running without errors:
`
systemctl status pmcd pmlogger
``
If you still encounter issues after following these steps, please review the PCP documentation or consider reaching out to Red Hat Support for further assistance.

이 해결 방법을 레드햇 KCS 에서 가져오는것이기 때문에 신뢰성이 높습니다. 내 컴퓨터에서 웹창을 안열고도 문제 해결을 할수있는것이지요.
단, 인터넷이 연결이 안된곳에서는 사용을 못하는 것이죠. insights 처럼요
사실, RedHat AI서버를 구축하면 사용은 가능할 것처럼 보이긴 합니다.
