0.5-5 2024-07-09 KAFS-CHECK-CONFIG(8)
Description
This program is used to check the configuration for the in-kernel AFS filesystem (kAFS). This
configuration is used when systemd mounts the filesystem to load up the cell database and create cell
automounts in the /afs directory.
The configuration is also used by the kernel name resolver upcall to provide static configuration for
some cells and to specify overrides and limits on DNS lookups.
If a list of "cellname" arguments is given, the listed cells will be dumped, including the sources of the
Volume Location records and address records.
Examples
To display the configuration for the default cell:
# kafs-check-config
=== Found cell some-cell.org ===
- use-dns=no
- show-cell=no
- status: no-lookup, from config
- VLSERVER shelter-4.some-cell.org [good; nss]
- address 10.0.0.48
- VLSERVER shelter-5.some-cell.org [good; nss]
- address 10.0.0.54
To display two specific cells:
# kafs-check-config ir.stanford.edu grand.central.org
=== Found cell ir.stanford.edu ===
- show-cell=no
- status: good, from SRV
- VLSERVER afsdb3.stanford.edu [good; nss]
- udp
- port 7003, pref 0, weight 0
- address 171.64.7.246
- VLSERVER afsdb2.stanford.edu [good; nss]
- udp
- port 7003, pref 0, weight 0
- address 171.64.7.234
- VLSERVER afsdb1.stanford.edu [good; nss]
- udp
- port 7003, pref 0, weight 0
- address 171.64.7.222
=== Found cell grand.central.org ===
- show-cell=no
- status: good, from SRV
- VLSERVER grand.mit.edu [good; nss]
- udp
- port 7003, pref 0, weight 0
- address 18.9.48.14
- VLSERVER grand-old-opry.central.org [good; nss]
- udp
- port 7003, pref 0, weight 0
- address 128.2.13.219
Exit Status

1 - If an error occurs during processing
2 - If a command line error occurs

Options
-4 Only show IPv4 addresses in the dump.
-6 Only show IPv6 addresses in the dump.
-P Dump the parse tree of the configuration file(s).
-D Dump the cell database extracted from the configuration.
-v Increase the verbosity of the output. This may be specified multiple times.
-c<conffile>
Specify a configuration file to read instead of the system default. This may be specified multiple
times and the configuration files are read and applied in order.
-N<restriction>
Apply a restriction to the lookup performed for the listed cells (if any are). Valid restrictions
include:
vl-srv
Don't use SRV records to find Volume Location servers.
vl-afsdb
Don't use AFSDB records to find Volume Location servers.
vl-all
Don't use SRV or AFSDB records to find Volume Location servers.
vl-host
