Resolving name-resolution failures with Linux SNX Technical Level
Symptoms
  • After connecting with SNX, the user may receive "host not found" errors when attempting to reach hosts inside the company's network. Name resolution may fail.
Cause
This issues occurs when the nsswitch.conf file includes the following declaration (or a similar one):hosts: files nis [NOTFOUND=return] dns
Solution
The /etc/nsswitch.conf file is used to configure which services are to be used, to determine information such as host names, password files, and group files. Modify the client's /etc/nsswitch.conf file, and remove the [NOTFOUND=return] from the "hosts" entry.

Procedure on SNX client:
  1. Edit the nsswitch.conf file:
    vi /etc/nsswitch.conf

  2. Locate the line:
    hosts: files nis [NOTFOUND=return] dns

  3. Remove the setting:
    [NOTFOUND=return]

  4. Save change and exit the vi editor.

  5. Reboot machine.

Results: Hosts should properly resolve host names to name server.
