Troubleshooting and Debugging Linux SMB Client Issues

A 22-minute conference presentation from SNIA SDC 2024 explores comprehensive troubleshooting techniques for Linux SMB client issues. Master practical debugging strategies using logs, trace points, CIFS proc file system debug files, and cifs-utils while learning to enable extended logs and effectively capture trace points. Discover methods for error location, SMB3 Wireshark trace analysis, and utilizing various SMB diagnostic tools for system-level diagnostics capture. Address common SMB challenges including mount failures, open handles, and connectivity issues through detailed analysis of traces, logs, and debug files. Get introduced to an upcoming eBPF-based diagnostics tools project designed for SMB client debugging. Gain hands-on experience with extended SMB client debug logs, learn to interpret diagnostic data including SMB Wireshark traces, and develop proficiency in identifying and resolving common SMB errors. Presented by Bharath S M from Microsoft, this talk equips participants with practical skills for confident Linux SMB client troubleshooting.
