Hi, thanks for the tip, however, they didn't work :-(
BTW, I'm using libCURL, not the binary. But just to be sure, I forced the usage
of the RSA keys in my app:
std::string szPrivKey(getenv("HOME"));
szPrivKey += "/.ssh/id_dsa";
curlCode = curl_easy_setopt(pCurl, CURLOPT_SSH_PRIVATE_KEYFILE,
szPrivKey.c_str());
if(curlCode != CURLE_OK)
std::cerr << "Couldn't set fragments transference options: " <<
curl_easy_strerror(curlCode) << " -> " << pErrorBuffer <<std::endl;
std::string szPubKey(getenv("HOME"));
szPubKey += "/.ssh/id_dsa.pub";
curlCode = curl_easy_setopt(pCurl, CURLOPT_SSH_PUBLIC_KEYFILE,
szPubKey.c_str());
if(curlCode != CURLE_OK)
std::cerr << "Couldn't set fragments transference options: " <<
curl_easy_strerror(curlCode) << " -> " << pErrorBuffer <<std::endl;
But still no success:
* Using ssh public key file /remote/home/alvaro/.ssh/id_rsa.pub
* Using ssh private key file /remote/home/alvaro/.ssh/id_rsa
* SSH public key authentication failed: Username/PublicKey combination invalid
I also tried one more time setting explicitly the DSA keys (not just using them
by default as before), no luck either:
* Using ssh public key file /remote/home/alvaro/.ssh/id_dsa.pub
* Using ssh private key file /remote/home/alvaro/.ssh/id_dsa
* SSH public key authentication failed: Username/PublicKey combination invalid
In fact, using CURL as a binary doesn't work either:

Any ideas?!?!?
