tftpd-hpa를 설치하면 자동으로 tftpd가 삭제된다.
$ sudo apt-cache search tftpd tftpd-hpa - HPA's tftp server atftpd - advanced TFTP server libnet-tftpd-perl - Perl extension for Trivial File Transfer Protocol Server tftpd - Trivial file transfer protocol server uec-provisioning-tftpd - the UEC Provisioning TFTP server |
글들을 보다 보니 --create가 TFTP_OPTIONS에 없으면 업로드 불가하다고 한다.
일단 nobody로 권한 통일
tftpd-hpa 설정파일 수정해주고
$ sudo vi /etc/default/tftpd-hpa # /etc/default/tftpd-hpa TFTP_USERNAME="nobody" TFTP_DIRECTORY="/tftpboot" TFTP_ADDRESS="0.0.0.0:69" TFTP_OPTIONS="--secure" |
xinetd 에서 서버 인자에 -B로 블럭 사이즈 늘려주고
$ sudo vi /etc/xinetd.d/tftp service tftp { protocol = udp socket_type = dgram wait = yes server = /usr/sbin/in.tftpd server_args = -s /tftpboot -B 1468 disable = no user = nobody } |
그럼 tftpd 쓸때 보다 빠르게 올려진다.

--blocksize max-block-size, -B max-block-size Specifies the maximum permitted block size. The permitted range for this parameter is from 512 to 65464. Some embedded clients request large block sizes and yet do not handle fragmented packets correctly; for these clients, it is recommended to set this value to the smallest MTU on your network minus 32 bytes (20 bytes for IP, 8 for UDP, and 4 for TFTP; less if you use IP options on your network.) For example, on a standard Ethernet (MTU 1500) a value of 1468 is reasonable. |

12.04에서 man으로 보니 BSD쪽 tftpd라 표준을 따르는 듯?
TFTPD(8) BSD System Manager's Manual TFTPD(8) NAME tftpd — DARPA Trivial File Transfer Protocol server SYNOPSIS tftpd [-n] [-s] [directory ...] DESCRIPTION Tftpd is a server which supports the DARPA Trivial File Transfer Pro‐ tocol. The TFTP server operates at the port indicated in the ‘tftp’ service description; see services(5). The server is normally started by inetd(8). The use of tftp(1) does not require an account or password on the remote system. Due to the lack of authentication information, tftpd will allow only publicly readable files to be accessed. Files may be written only if they already exist and are publicly writable. Note that this extends the concept of “public” to include all users on all hosts that can be reached through the network; this may not be appro‐ priate on all systems, and its implications should be considered before enabling tftp service. The server should have the user ID with the lowest possible privilege. Access to files may be controlled by invoking tftpd with a list of directories by including pathnames as server program arguments in /etc/inetd.conf. In this case access is restricted to files whose names are prefixed by the one of the given directories. If no directo‐ ries are supplied the default is /tftpboot. To give out access to the whole filesystem, should this be desired for some reason, supply / as an argument. Unfortunately, on multi-homed systems, it is impossible for tftpd to determine the address on which a packet was received. As a result, tftpd uses two different mechanisms to guess the best source address to use for replies. If the socket that inetd(8) passed to tftpd is bound to a particular address, tftpd uses that address for replies. Otherwise, tftpd uses ``UDP connect'' to let the kernel choose the reply address based on the destination of the replies and the routing tables. This means that most setups will work transparently, while in cases where the reply address must be fixed, the virtual hosting fea‐ ture of inetd(8) can be used to ensure that replies go out from the correct address. These considerations are important, because most tftp clients will reject reply packets that appear to come from an unexpected address. The options are: -n Suppresses negative acknowledgement of requests for nonexis‐ tent relative filenames. -s All absolute filenames are treated as if they were preceded by the first directory argument, or /tftpboot if there is none. SEE ALSO tftp(1), inetd(8) HISTORY The tftpd command appeared in 4.2BSD. Linux NetKit (0.17) July 29, 2000 Linux NetKit (0.17) |
tftpd 클라이언트로 받아보니 이렇게 뜬다.
tftp> get tt.yaffs2 getting from localhost:tt.yaffs2 to tt.yaffs2 [netascii] sent RRQ <file=tt.yaffs2, mode=netascii> received DATA <block=10926, 512 bytes> discarded 2 packets received DATA <block=1, 512 bytes> sent ACK <block=1> |
RFC에 따라 512 byte가 기본인듯
물론
ubuntu 12.04 tftp 를 이용해서 tftpd32의 것을 받으니.. 여전히 512로 받는데..
클라이언트와 서버 둘다 표준을 준수하는(?) 착한 녀석들 이라 그런 듯

There is a current limiter (load switch) IC on the VBUS. It is shared by 3 USB host ports. Total output current is about 1.6A at max. At the maximum load, the output voltage can be down to 4.6~4.7Volt. It this worst case, you may need to consider to use 3 Amp power supply because CPU/RAM/GPU can eat about 1 Amp. Which USB devices are considered ? |
VLC doesn't run well on the ARMHF platform. As an alternative, use Gxine for a quick-and-easy software decoded video player, or install the optimized hardware-decoded version of XBMC available here: http://oph.mdrjr.net/robroyhall/software/linux/xbmc/. XBMC works best in 720p, and Gxine will drop frames sometimes but still manages to stay smooth and in sync. |

간단하게 정리하면..
eMMC 쓰면 ext4 써도 무난(eMMC에서 셀 관리 하니)
NAND에서는 yaffs가 무난(NAND는 셀 관리 기능이 없으므로)
다만. 안드로이드에서 2.3 버전 이후 바꾼 이유는
성능 저하로 인해(yaffs가 single thread라는데 무슨 의미인지..) 그렇다고
The problem with YAFFS, T'so explained in his blog entry, is that it is single-threaded and would likely "have been a bottleneck on dual-core systems." Concurrency will be important on next-generation Android devices that use multi-core ARM processors. |
