NAME

6       charon-cmd - Simple IKE client (IPsec VPN client)

SYNOPSIS

9       charon-cmd --host hostname --identity identity [ options ]
10

DESCRIPTION

12       charon-cmd  is a program for setting up IPsec VPN connections using the
13       Internet Key Exchange protocol (IKE) in version 1 and 2.  It supports a
14       number of different road-warrior scenarios.
15
16       Like  the  IKE daemon charon, charon-cmd has to be run as root (or more
17       specifically as a user with CAP_NET_ADMIN capability).
18
19       Of the following options at least --host and --identity  are  required.
20       Depending  on the selected authentication profile credentials also have
21       to be provided with their respective options.
22
23       Many of the charon-specific configuration  options  in  strongswan.conf
24       also  apply  to charon-cmd.  For instance, to configure customized log‐
25       ging to stdout the following snippet can be used:
26
27            charon-cmd {
28                 filelog {
29                      stdout {
30                           default = 1
31                           ike = 2
32                           cfg = 2
33                      }
34                 }
35            }
36

40
41       --version
42              Prints the strongSwan version.
43
44       --debug level
45              Sets  the  default log level (defaults to 1).  level is a number
46              between -1 and 4.  Refer to  strongswan.conf  for  options  that
47              allow a more fine-grained configuration of the logging output.
48
49       --host hostname
50              DNS name or IP address to connect to.
51
52       --identity identity
53              Identity the client uses for the IKE exchange.
54
55       --eap-identity identity
56              Identity the client uses for EAP authentication.
57
58       --xauth-username username
59              Username the client uses for XAuth authentication.
60
61       --remote-identity identity
62              Server identity to expect, defaults to hostname.
63
64       --cert path
65              Trusted  certificate,  either  for authentication or trust chain
66              validation.  To  provide  more  than  one  certificate  multiple
67              --cert options can be used.
68
69       --rsa path
70              RSA  private  key  to  use  for authentication (if a password is
71              required, it will be requested on demand).
72
73       --p12 path
74              PKCS#12 file with  private  key  and  certificates  to  use  for
75              authentication  and  trust  chain  validation  (if a password is
76              required it will be requested on demand).
77
78       --agent[=socket]
79              Use SSH agent for authentication. If socket is not specified  it
80              is read from the SSH_AUTH_SOCK environment variable.
81
82       --local-ts subnet
83              Additional  traffic  selector  to  propose  for  our  side,  the
84              requested virtual IP address will always be proposed.
85
86       --remote-ts subnet
87              Traffic  selector  to  propose  for  remote  side,  defaults  to
88              0.0.0.0/0.
89
90       --ike-proposal proposal
91              IKE  proposal  to  offer instead of default. For IKEv1, a single
92              proposal consists of one encryption algorithm, an  integrity/PRF
93              algorithm  and a DH group. IKEv2 can propose multiple algorithms
94              of the same kind. To  specify  multiple  proposals,  repeat  the
95              option.
96
97       --esp-proposal proposal
98              ESP  proposal  to  offer instead of default. For IKEv1, a single
99              proposal consists of  one  encryption  algorithm,  an  integrity
100              algorithm  and  an optional DH group for Perfect Forward Secrecy
101              rekeying. IKEv2 can propose  multiple  algorithms  of  the  same
102              kind. To specify multiple proposals, repeat the option.
103
104       --ah-proposal proposal
105              AH  proposal  to  offer instead of ESP. For IKEv1, a single pro‐
106              posal consists of an integrity  algorithm  and  an  optional  DH
107              group  for  Perfect  Forward Secrecy rekeying. IKEv2 can propose
108              multiple algorithms of the same kind. To specify  multiple  pro‐
109              posals, repeat the option.
110
111       --profile name
112              Authentication  profile  to  use, the list of supported profiles
113              can be found in  the  Authentication  Profiles  sections  below.
114              Defaults  to  ikev2-pub  if  a  private key was supplied, and to
