Unable to deploy Agent to Macs - ERA 6.2.171.0 Started by Dave Featherstone , Dec 11 2015 09:29 AM Reply to this topic 1 reply to this topic #1 Dave Featherstone Dave Featherstone Group: Members Posts: 1 Kudos: 0 Joined: 11-December 15 Posted 11 December 2015 - 09:29 AM Hi, I'm trying to deploy the agent to a Macbook http://stackoverflow.com/questions/37805479/libssh2-version-0-19-0-20080814-getting-error-5-everytime-while-calls-libssh2-s but it's failing. I've done this in the past successfully but not since the upgrade to ERA 6.2. I've checked the suggestions the error makes and I'm able to log onto the Macbook using SSH and the account I'm using has sudo rights.

exchange encryption keys This message: [ Message body ] [ More options ] Related messages: [ Next message ] [ Previous message https://c-ares.haxx.se/mail/libssh2-devel-archive-2009-12/0104.shtml ] [ Next in thread ] [ Replies ] From: Oliver https://github.com/datacratic/libssh2/tree/master/example Nelson Date: Tue, 29 Dec 2009 22:40:43 -0800 I've done some more work on this problem. Using the released version of 1.2.2 now. I haven't been able to get libssh2 debug mode to work for some odd reason (my fault no doubt), but libssh2_session_startup error I did get some debug output from my openssh server which all looked fine. Upon further investigation, I can see that in the session object, the SHA1 and MD5 hash of the encryption key is shown correctly (based on looking at the fingerprint from another client connecting to the same host). This seems to indicate libssh2_session_startup error that the key exchange is working, but libssh2_session_hostkey returns an empty string. I get this behaviour on any host I connect to. My test code looks like this: int iretval; unsigned long mode = 1; int last_socket_err = 0; int other_port = 0; fd_set read_set, write_set; char *ssh_addr; size_t len; int type; addrinfo * result = NULL; addrinfo hints; DWORD retval; ZeroMemory(&hints, sizeof(hints)); hints.ai_family = AF_INET; hints.ai_socktype = SOCK_STREAM; hints.ai_protocol = IPPROTO_TCP; retval = getaddrinfo("173.12.216.189", "222",&hints,&result); SOCKET sshsock = socket(AF_INET, SOCK_STREAM, 0); iretval = connect(sshsock, result->ai_addr, result->ai_addrlen); LIBSSH2_SESSION * session = NULL; session = libssh2_session_init(); iretval = libssh2_session_startup(session, sshsock); if (iretval) ::PostQuitMessage(0); LIBSSH2_KNOWNHOSTS * hosts; hosts = libssh2_knownhost_init(session); const char* fingerprint = libssh2_session_hostkey(session,&len,&type); Now, I could use libssh2_hostkey_hash (which returns a correct fingerprint) and do the check myself, but I think I'm supposed to call libssh2_knownhost_check which seems to want the whole key, not just the fingerprint of the key. Is there something wrong with my code here? NOTE: You can
