You can use traceroute to see whether any of the hops have a large latency or whether the latency between each hop is consistent. It also shows the latency (or delay) in milliseconds for each step of the path. It sends a packet and displays a list of the jumps or routers the packet goes through along with the IP addresses for each jump. Traceroute, or tracert, uses what are called вЂњecho packetsвЂќ to look at the path between your location and a remote destination.

In Windows operating systems, the command is called tracert.

It comes as a command-line tool in Unix systems, and itвЂ™s available on Mac OS as a graphical traceroute tool through a network utility. Traceroute is a command used for network troubleshooting. My recommended tools are SolarWinds В® Network Performance Monitor (NPM) and SolarWinds EngineerвЂ™s Toolset в„ў (ETS). As this guide will show, a good traceroute alternative can provide a more complete picture of the issues facing your network while helping make things easier for IT staff and administrators. But despite its longevity and widespread usage, there are other, more modern tools capable of helping you with the same problems traceroute is designed to address. Traceroute has been around for a long time. Traceroute can then determine whether any delays or losses occur along the way and help you pinpoint where exactly a packet gets slowed down. It works by tracking packets as they move between computers and examining the path they take.

Restart your computer and Ubuntu should boot properly.ДЇor more detailed technical information, including how to use the chroot command to gain access to a broken Ubuntu systemвЂ™s files and restore GRUB2, consult the Ubuntu wiki.Traceroute is one of the most widely used tools for network troubleshooting. sudo grub-install -boot-directory=/mnt/ubuntu/boot /dev/sdX For example, if you used /dev/sda1 above, use /dev/sda here. Run the following command to reinstall grub from the live CD, replacing /dev/sdX with the device name of the hard disk above.

If you donвЂ™t know whether you have a separate boot partition, you probably donвЂ™t. Important: If you have a separate boot partition, skip the above command and mount the boot partition at /mnt/ubuntu/boot instead.

This means the first partition on the first hard disk device. In the screenshot above, our Ubuntu partition is /dev/sda1. Run the following commands to mount the Ubuntu partition at /mnt/ubuntu, replacing /dev/sdX# with the device name of your Ubuntu partition from the above commands: sudo mkdir /mnt/ubuntu If you have multiple Linux ext4 partitions, you can getВ an idea of which is which by viewing the size of the partitions and their order on the disk here. In the blkid command, the partition is identified by its ext4В file system. In the fdisk -l command, the Ubuntu partition is identified by the word LinuxВ in the System column. Identify the partition Ubuntu is installed on using one of the following commands: sudo fdisk -l Open a terminal after booting into the live environment. For example, if you have Ubuntu 14.04 installed, ensure you use a Ubuntu 14.04 live CD. Ensure the version of Ubuntu on the CD is the same as the version of Ubuntu installed on your computer. YouвЂ™ll need to boot from a live CD or USB drive, as in the graphical method above. If youвЂ™d rather get your hands dirty, you can do this yourself from a terminal. Restart your computer after the Boot Repair tool finishes applying its changes. The tool will walk you through everything you need to do.

Perform the instructions Boot Repair wants you to and click вЂњForwardвЂќ to continue through the wizard. Just follow the instructions that appear on your screen.

It may ask you to open a Terminal and copy/paste a few commands into it. The recommended repair option can fix most problems automatically, and you could mess up your system even more by selecting the wrong advanced options.Д«oot Repair will begin working. You can choose to use the advanced options here, but UbuntuвЂ™s wiki recommends you not use the advanced options unless you know what youвЂ™re doing. After it scans your system, click the вЂњRecommended repairвЂќ button to repair GRUB2 with a single click. The Boot Repair window will automatically scan your system after you run the boot-repair command.

Open a Terminal window from the Dash and run the following commands to install and launch Boot Repair: sudo apt-add-repository ppa:yannubuntu/boot-repair You may need to choose a Wi-Fi network and enter its passphrase. When Ubuntu boots, click вЂњTry UbuntuвЂќ to get a usable desktop environment.Д®nsure you have an Internet connection before continuing.
