Mengatasi FTP Transfer VSFTPD Lambat Lemot

Pada kasus saya, transfer ke server FTP (vsftpd) sangat lambat dan sering gagal.

Ternyata kendalanya ada di max connection, cukup tambahkan

max_per_ip=20

Pada /etc/vsftpd.conf agar koneksi dapat berjalan paralel dan cepat.

Install Node 18+ di Ubuntu 18-

 

sudo -i

# Start by installing Node 20:

sudo apt-get install python3 g++ make python3-pip gcc bison

curl -L https://raw.githubusercontent.com/tj/n/master/bin/n -o n
bash n 20

# Node 20 is now at /usr/local/bin/node, but glibc 2.28 is missing:
# node: /lib/aarch64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by node)
# /usr/local/bin/node: /lib/aarch64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by /usr/local/bin/node)

# Build and install glibc 2.28:
apt install -y gawk
cd ~
wget -c https://ftp.gnu.org/gnu/glibc/glibc-2.28.tar.gz
tar -zxf glibc-2.28.tar.gz
cd glibc-2.28
pwd
mkdir glibc-build
cd glibc-build
../configure --prefix=/opt/glibc-2.28
make -j 4 # Use all 4 Jetson Nano cores for much faster building
make install
cd ..
rm -fr glibc-2.28 glibc-2.28.tar.gz
 
# Patch the installed Node 20 to work with /opt/glibc-2.28 instead: 
apt install -y patchelf
patchelf --set-interpreter /opt/glibc-2.28/lib/ld-linux-x86-64.so.2 --set-rpath /opt/glibc-2.28/lib/:/lib/x86_64-linux-gnu/:/usr/lib/x86_64-linux-gnu/ /usr/local/bin/node

# Et voilà:
node --version
v20.9.0
