Logging is performed via a standard logging object set in TftpShared.N)*)TftpContextClientDownloadTftpContextClientUploadztftpy.TftpClientc:eZdZdZdidfdZdeefdZdeefdZy) TftpClientzThis class is an implementation of a tftp client. Once instantiated, a download can be initiated via the download() method, or an upload via the upload() method.Ec6tj|d|_||_||_d|_||_||_d|j vrL|j d}ttt|k(d|tks |tkDrtd|zyy)Nblksizezblksize must be an intzInvalid blksize: %d) TftpSession__init__contexthostiportfilenameoptionslocalip tftpassertinttype MIN_BLKSIZE MAX_BLKSIZE TftpException)selfrportrrsizes 5/usr/lib/python3.12/site-packages/tftpy/TftpClient.pyrzTftpClient.__init__sT"       $<< *D sd4j(*B Ck!TK%7#$9D$@AA&8 %Nc tjdtjd|jd|jd|tjd|jd|d|t |j|j|||j||||j  |_|jj|jj|jj}tjd tjd |jd k(rtjd nPtjd |j|jfztjd|jztjd|jztjd|j zy)aTThis method initiates a tftp download from the configured remote host, requesting the filename passed. It writes the file to output, which can be a file-like object or a path to a local file. If a packethook is provided, it must be a function that takes a single parameter, which will be a copy of each DAT packet received in the form of a TftpPacketDAT object. The timeout parameter may be used to override the default SOCK_TIMEOUT setting, which is the amount of time that the client will wait for a receive packet to arrive. The retires paramater may be used to override the default DEF_TIMEOUT_RETRIES settings, which is the amount of retransmission attemtpts the client will initiate after encountering a timeout. Note: If output is a hyphen, stdout is used.z4Creating download context with the following params:zhost = z , port = z , filename = z options = z, packethook = z , timeout = retriesrr zDownload complete.r%Duration too short, rate undeterminedz%Downloaded %.2f bytes in %.2f secondsAverage rate: %.2f kbps%.2f bytes in resent datazReceived %d duplicate packetsN)logdebugrrrrrrstartendmetricsinfodurationbyteskbps resent_bytesdupcount)rroutput packethooktimeoutr"r*s rdownloadzTftpClient.download#sH HI 499djjRZ[\ 4< ,w/C/CCD 073C3CCDrc t|j|j|||j||||j |_|j j |j j|j j}tjdtjd|jdk(rtjdnPtjd|j|jfztjd|jztjd|jztjd |jzy ) aTThis method initiates a tftp upload to the configured remote host, uploading the filename passed.
