howmount -e 192.168

The command "howmount -e 192.168" seems to be a typo or not a standard Linux command. In Unix-like systems, "howmount" is typically used with the "-t" option followed by a file system type to mount a remote or local filesystem. If you meant to specify an IP address for mounting, it's more likely to use "mount" command.

If you were trying to manually mount a network share on a specific subnet (like 192.168.x.x), the correct syntax would be something like this:

sudo mount -t cifs //192.168.x.x/sharename /mnt/network_share -o username=user,password=pass,credentials=/path/to/credentials_file

Here, replace `sharename` with the actual shared folder name, `x.x` with the appropriate subnet, `user` and `pass` with your credentials, and `/path/to/credentials_file` if using a separate file to store them securely.

Without additional context, it's unclear what exactly you're asking about, as the `-e` flag doesn't have a default meaning in the `howmount` utility. If you're looking for help with mounting a network drive, please provide more details.
