The garbage varies from one attempt to the next. This occurs even when using "ftp localhost." It does not occur when transferring from a UFS mount or when transferring in ASCII mode, or when the file is larger than 2872 bytes. The problem does not occur when accessing the smbfs-mounted file by other means (e.g., ex/vi, cp, or even copying to a Windows box via a Samba share). tcpdump during the corrupted ftp shows that data moves correctly from smbfs-mounted machine to FreeBSD but is incorrect by the time it leaves FreeBSD (via ftpd) for its final destination. Reproduced on two machines running different 4.3-STABLE snapshots. Transfers using wu-ftpd-2.6.1 work properly. >How-To-Repeat: Mount a Windows share via smbfs, ftp localhost on the FreeBSD box, log in and change to binary mode, and get a file of2872 bytes or less from somewhere under the smbfs mount point. Compare original and transferred files. >Fix: Workaround: Copy the needed file via means other than ftp to a UFS mount before getting it with FTP, or use a different ftpd. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
