This article mainly introduces "how to solve ifconfig without output". In daily operation, I believe many people have doubts about how to solve ifconfig without output. Xiaobian consulted all kinds of information and sorted out simple and easy operation methods. I hope to help you answer the doubts of "ifconfig without output"! Next, please follow the small series to learn together!

Linux ifconfig command is used to display or set network devices, ifconfig can set the status of network devices, or display the current settings, there are some small partners in the use of ifconfig command encountered no input situation.

problem

Executing ifconfig command without any errors and without any output messages

[root@linuxprobe ~]# ifconfig[root@linuxprobe ~]#Mistake 1. Check PATH variable [root@linuxprobe ~]# echo $PATH/usr/local/bin: /usr/local/sbin: /usr/sbin:/bin:/sbin:/root/bin

If the path/sbin is not in the PATH variable, execute the following command to add it.

export PATH=$PATH:/sbin

Note: PATH variable is normal in this example

2. Check/sbin/ifconfig

Under normal circumstances, if ifconfig is displayed, but there is no information about a certain item (such as not identifying the network card), you can first check whether the configuration file under/etc/sysconfig/network-scripts/is correct. However, in this case, since the execution of ifconfig and/sbin/ifconfig does not produce any output, the following/sbin/ifconfig file is checked first. The following errors were found:

[root@linuxprobe ~]# ls -la /sbin/ifconfig-rwxr-xr-x 1 root root 0 Apr 5 14:56 /sbin/ifconfig[root@linuxprobe ~]# file /sbin/ifconfig/sbin/ifconfig: empty3. solution

copy a copy of/sbin/ifconfig to this machine from another machine on the local area network using the scp command

[root@yezi ~]# scp /sbin/ifconfig root@192.168.10.10:/sbinThe authenticity of host '192.168.10.10 (192.168.10.10)' can't be established.ECDSA key fingerprint is b2:e4:20:20:ae:ae:2e:20:ce:49:76:05:bd:c4:42:39.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added '192.168.10.10' (ECDSA) to the list of known hosts.root@192.168.10.10's password:ifconfig 100% 80KB 80.1KB/s 00:00

If you run ifconfig again, you can display it normally.
