# This is the ssh client system-wide configuration file. See

# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the

คุณเคยลองผู้ใช้คนอื่น? หรือเปลี่ยนรหัสผ่านสำหรับอันนี้?

fboaventura
ฉันเห็นด้วยกับ fboaventura; การกำหนดค่าดูดี ลองเปลี่ยนรหัสผ่านสำหรับผู้ใช้ของคุณเป็นสิ่งที่คุณคิดว่ามันควรจะตรวจสอบว่ามันไม่หมดอายุ / บัญชีถูกล็อค และลองผู้ใช้รายอื่นในกรณี นอกจากนี้คุณยังสามารถเข้าสู่ระบบในฐานะผู้ใช้นั้นได้หรือไม่? นั่นคือข้อผิดพลาดเฉพาะกับ SSH หรือมีข้อผิดพลาดผ่านการตรวจสอบความถูกต้องอื่น ๆ

@ fboaventura & Justin ฉันลองใช้ผู้ใช้คนอื่นแล้วฉันก็เปลี่ยนรหัสผ่านและลองอีกครั้งโดยไม่ประสบความสำเร็จ ฉันสามารถเข้าสู่ระบบในเครื่องได้และฉันยังสามารถ SSH ไปยัง localhost ได้ด้วย
