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

Prosedur Start Server Kafka 2.13

 Start Server Service

./bin/kafka-server-start.sh ./config/kraft/server.properties

Error Unformatted

 ./bin/kafka-storage.sh random-uuid

 ./bin/kafka-storage.sh format -t wTJ2_4vKQcujLyzgVBznow -c config/kraft/server.properties

Connect Standalone

Start Connect-Standalone

./bin/connect-standalone.sh config/connect-standalone.properties config/cassandra-sink-standalone.properties

Topics

 ./bin/kafka-configs.sh --bootstrap-server 10.102.235.46:9092 --alter --entity-type topics --entity-name kapalpatroli --add-config segment.bytes=32768,min.compaction.lag.ms=1000,min.cleanable.dirty.ratio=0.01,delete.retention.ms=100,segment.ms=100,cleanup.policy=compact,retention.ms=1000

 ./bin/kafka-topics.sh --bootstrap-server 10.102.235.46:9092 --create --topic kapalpatroli --partitions 6 --replication-factor 1 --config cleanup.policy=compact --config retention.ms=1000

Menambah Kapasitas Disk/Storage KVM Virtual Machine

Extend Block Device

$ lsblk 

 NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
 sr0            11:0    1 1024M  0 rom  
 vda           252:0    0   30G  0 disk
 ├─vda1        252:1    0    1G  0 part /boot
 └─vda2        252:2    0   29G  0 part
   ├─rhel-root 253:0    0 26.9G  0 lvm  /
   └─rhel-swap 253:1    0  2.1G  0 lvm  [SWAP]

Pada contoh di atas kita akan mengubah vda menjadi 40G

1. Shut Down Virtual Machine

$ sudo virsh shutdown [domain_name]

2. Extend KVM Guest OS Disk

Cari lokasi OS disk path

$ sudo virsh domblklist [domain_name]

Target   Source
-----------------------------------------------
vda      /var/lib/libvirt/images/rhel8.qcow2
sda      -

$ sudo qemu-img info /var/lib/libvirt/images/rhel8.qcow2

image: /var/lib/libvirt/images/rhel8.qcow2
file format: qcow2
virtual size: 30G (42949672960 bytes)
disk size: 2.0G
cluster_size: 65536
Format specific information:
    compat: 1.1
    lazy refcounts: true
    refcount bits: 16
    corrupt: false

$ sudo qemu-img resize /var/lib/libvirt/images/rhel8.qcow2 +10G

Atau dapat juga menggunakan virsh

$ sudo virsh blockresize [domain_name] [os_disk_path]

3. Check Result

$ lsblk 

 NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
 sr0            11:0    1 1024M  0 rom  
 vda           252:0    0   40G  0 disk
 ├─vda1        252:1    0    1G  0 part /boot
 └─vda2        252:2    0   29G  0 part
   ├─rhel-root 253:0    0 26.9G  0 lvm  /
   └─rhel-swap 253:1    0  2.1G  0 lvm  [SWAP]

Resize Partition dan File System

$ sudo growpart /dev/vda 1

$ sudo resize2fs [partition_path]

Mengatasi Error Github gnutls_handshake() failed: Error in the pull function

Pada saat melakukan operasi git pada server linux, terkadang muncul error

gnutls_handshake() failed: Error in the pull function

Error tersebut terjadi karena ketidaksesuaian MTU pada server kita dengan MTU yang dipersyaratkan di server host / proxy. Pada case ini, MTU kita terlalu tinggi dari yang dipersyaratkan. [1]

Untuk mengatasinya, maka kita perlu menurunkan MTU pada interface server kita. Pada kasus saya, menggunakan nilai MTU 1400 dapat mengatasi error ini.

Konfigurasi MTU pada Interface Linux

Cara Mengecek MTU Interface

ifconfig <interface_name> | grep mtu

Cara Mengubah MTU Interface

ifconfig <interface_name> mtu <nilai_mtu> up

Misal

ifconfig eth0 mtu 1400 up

Konfigurasi di atas tidak permanen, untuk melakukan konfigurasi permanen silahkan cek [2].
