in thread SFTP Protocal

The 6th line of DH.pm has use Math::BigInt lib => "GMP,Pari"; My program got segmentation fault after gettting the below error . Herewith I have mentioned the debug log of my program ,Please look at this Reading configuration data /root/.ssh/config Reading configuration data /etc/ssh_config Allocated local port 1023. Connecting to 192.168.1.130, port 22. Remote protocol version 2.0, remote software version OpenSSH_4.3p2 Debian-9 Math::BigInt: couldn't load specified math lib(s), fallback to Math::BigInt::FastCalc at /usr/lib/perl5/site_perl/5.6.1/Crypt/DH.pm line 6 Net::SSH::Perl Version 1.34, protocol version 2.0. No compat match: OpenSSH_4.3p2 Debian-9. Connection established. Sent key-exchange init (KEXINIT), wait response.

    The 6th line of DH.pm has use Math::BigInt lib => "GMP,Pari";

    That means it will try to use Math::BigInt::GMP. If that fails it will try to use Math::BigInt::Pari. If that also fails it will use Math::BigInt::FastCalc and print out the message.

    I would be surprised if installing Math::BigInt::GMP would fix the segfault. I would think the segfault is being caused by a different issue - but I don't know what that issue is.

    I think that In perl5.6.0 , doesn't has GMP and Pari files.

    Without GMP and Pari, I don't think you would have been able to get Net::SSH::Perl to install - but I've never used Net::SSH::Perl, and am no expert.
    Instead, I use Net::SSH2 - which needs the libssh2 library.
    I *think* Net::SFTP also provides good mileage on linux - though I've never used it either, as I'm on Windows.

    Cheers,
    Rob

    We could help you more if you can post some code. Meanwhile, GMP would require The GNU MP Bignum Library. Do you have libgmp installed? Ordinarily, I would say that Math::Pari wasn't working, but it seems to be working. Check that you have all the dependencies installed. If you need some help posting some code, just ask-:).
