Masalahnya
“Sesi non-anonim harus menggunakan enkripsi” terjadi saat menjalankan perintah curl sebagai pengguna root:
# curl -v -k --ftp-ssl --ftp-pasv ftp://192.168.X.X:990/ --user hcpa:XXX * About to connect() to 192.168.X.X port 990 (#0) * Trying 192.168.X.X... connected * Connected to 192.168.X.X (192.168.X.X) port 990 (#0) < 220 FTP SERVER INFOVALMER. > USER hcpa < 530 Non-anonymous sessions must use encryption. * Access denied: 530 * Closing connection #0 curl: (67) Access denied: 530
Namun itu berfungsi saat menjalankan perintah curl yang sama dengan pengguna non-root:
# exit logout
# su - testuser $ curl -v -k --ftp-ssl --ftp-pasv ftp://192.168.X.X:990/ --user hcpa:XXX * About to connect() to 192.168.10.1 port 990 (#0) * Trying 192.168.X.X... connected * Connected to 192.168.X.X (192.168.X.X) port 990 (#0) < 220 FTP SERVER INFOVALMER. > AUTH SSL < 234 Proceed with negotiation. * Initializing NSS with certpath: /etc/pki/nssdb * warning: ignoring value of ssl.verifyhost * skipping SSL peer certificate verification * NSS: client certificate not found (nickname not specified) * SSL connection using SSL_RSA_WITH_3DES_EDE_CBC_SHA * Server certificate: * subject: ,CN=ftp-infovalmer,OU=VALORADOR,O=INFOVALMER,L=BOGOTA,ST=CUNDINAMARCA,C=CO * start date: sep 10 22:11:55 2015 GMT * expire date: sep 09 22:11:55 2018 GMT * common name: ftp-infovalmer * issuer: @ ,CN=ftp-infovalmer,OU=VALORADOR,O=INFOVALMER,L=BOGOTA,ST=CUNDINAMARCA,C=CO > USER hcpa < 331 Please specify the password. > PASS XXX < 230 Login successful.
Solusinya
Tambahkan $LD_LIBRARY_PATH variabel lingkungan di /root/.bash_profile .
/usr/bin/curl mencari direktori /apps/MATLAB/v81/bin/glnxa64/ saat mencari library libcurl.so.4:
# ldd /usr/bin/curl linux-vdso.so.1 => (0x00007fffc9f7d000) libcurl.so.4 => /apps/MATLAB/v81/bin/glnxa64/libcurl.so.4 (0x00007f291de7b000) <----- libidn.so.11 => /lib64/libidn.so.11 (0x0000003201600000) libldap-2.4.so.2 => /lib64/libldap-2.4.so.2 (0x00000033afc00000) librt.so.1 => /lib64/librt.so.1 (0x00000033ab400000) libgssapi_krb5.so.2 => /lib64/libgssapi_krb5.so.2 (0x00000032bba00000) libkrb5.so.3 => /lib64/libkrb5.so.3 (0x00000032bc200000)
Dalam keadaan normal, /usr/bin/curl seharusnya mencari direktori /usr/lib64/ saat mencari perpustakaan libcurl.so.4:
# ldd /usr/bin/curl linux-vdso.so.1 => (0x00007fff8dbe1000) libcurl.so.4 => /usr/lib64/libcurl.so.4 (0x00000033ac400000) <----- libidn.so.11 => /lib64/libidn.so.11 (0x0000003201600000) libldap-2.4.so.2 => /lib64/libldap-2.4.so.2 (0x00000033afc00000) librt.so.1 => /lib64/librt.so.1 (0x00000033ab400000) libgssapi_krb5.so.2 => /lib64/libgssapi_krb5.so.2 (0x00000032bba00000) libkrb5.so.3 => /lib64/libkrb5.so.3 (0x00000032bc200000)
1. Menambahkan variabel lingkungan $LD_LIBRARY_PATH di /root/.bash_profile akan memengaruhi semua aplikasi yang berjalan sebagai pengguna root, jadi hapus LD_LIBRARY_PATH di /root/.bash_profile terlebih dahulu;
2. Kemudian tentukan jalur pencarian run-time saat mengkompilasi aplikasi matlab, silakan berkonsultasi dengan vendor aplikasi matlab dan periksa apakah ada cara untuk mencapainya.
Atau
Setel LD_LIBRARY_PATH saat menjalankan program, misalnya:
# LD_LIBRARY_PATH=./app_test
"LD_LIBRARY_PATH=[PATH]b" hanya berlaku saat menjalankan perintah di atas, tidak akan memengaruhi aplikasi lain.
