I get this same problem using the example sftp.c program that is provided with libssh2. I noticed it when I was first going to check the changes you were doing for the speed because I was curious about it, however I have no personal applications that use libssh2 so I just used your examples. It still occurs with the latest CVS updates. When I run it, I get the following: kic...@bonzi:~/libssh2/libssh2/example/simple$ ./sftp 192.168.0.3 username password /tmp/TEST Fingerprint: E5 2C 2C 13 5A AD CC 30 D7 03 31 8A 6E 42 39 14 Authentication methods: publickey,password libssh2_sftp_init()! Unable to init SFTP session all done After libssh2_sftp_init() is printed, it stalls for a little while, then continues. Running it in gdb, and using ctrl+c to interrupt when it calls, brings this backtrace: (gdb) bt #0 0xffffe410 in __kernel_vsyscall () #1 0xb7f18421 in recv () from /lib/tls/i686/cmov/libc.so.6 #2 0xb7fac643 in _libssh2_packet_read (session=0x804b008) at transport.c:362 #3 0xb7f900dc in libssh2_channel_read_ex (channel=0x804fea8, stream_id=0, buf=0xbfed82d4 "\001", buflen=4) at channel.c:1515 #4 0xb7fa2270 in sftp_packet_read (sftp=0x8050f38) at sftp.c:154 #5 0xb7fa272f in sftp_packet_require (sftp=0x8050f38, packet_type=2 '\002', request_id=0, data=0xbfed8364, data_len=0xbfed8360) at sftp.c:303 #6 0xb7fa32df in libssh2_sftp_init (session=0x804b008) at sftp.c:645 #7 0x08049385 in main (argc=5, argv=0xbfed88c4) at sftp.c:203 -- Keith Maika http://aoeex.com/ - Personal site http://www.gnu.org/philosophy/can-you-trust.html - Can you trust your computer? http://www.gnu.org/philosophy/no-word-attachments.html - Support Open Communication. ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
