# netkit-rlogin(1)

remote login

## NAME

**rlogin** – remote login

## SYNOPSIS

*rlogin* \[**-8EKLd**\] \[**-e** *char*\] \[**-i** *identity*\] \[**-l** *username*\] \[**-p** *port*\] *host*

## DESCRIPTION

**Rlogin** starts a terminal session on a remote host *host*.

**Rlogin** first attempts to use the Kerberos authorization mechanism, described below. If the remote host does not supporting Kerberos the standard Berkeley *rhosts* authorization mechanism is used. The options are as follows:

- **-8**

  The **-8** option allows an eight-bit input data path at all times; otherwise parity bits are stripped except when the remote side's stop and start characters are other than ^S/^Q .

- **-i**

  The **-i** option specifies the local user name to use for authentication with the remote **rlogind** server.  This overrides the default which is the name of the user invoking **rlogin**.

- **-l**

  The **-l** option specifies the name of the remote user to login as.  This overrides the default which is the name of the user invoking **rlogin**.

- **-E**

  The **-E** option stops any character from being recognized as an escape character. When used with the **-8** option, this provides a completely transparent connection.

- **-K**

  The **-K** option turns off all Kerberos authentication.  This option has no effect since Kerberos authentication is not available in this version.

- **-L**

  The **-L** option allows the rlogin session to be run in \`\`litout'' (see [tty(4)](/tty/4.md)) mode.

- **-d**

  The **-d** option turns on socket debugging (see [setsockopt(2)](/setsockopt/2.md)) on the TCP sockets used for communication with the remote host.

- **-e**

  The **-e** option allows user specification of the escape character, which is \`\`~'' by default. This specification may be as a literal character, or as an octal value in the form \\nnn.

- **-p**

  The **-p** option specifies the port to connect to.  This overrides the default which is **login**.

A line of the form \`\`\<escape char\>.'' disconnects from the remote host. Similarly, the line \`\`\<escape char\>^Z'' will suspend the **rlogin** session, and \`\`\<escape char\>\<delayed-suspend char\>'' suspends the send portion of the rlogin, but allows output from the remote system. By default, the tilde (\`\`~'') character is the escape character, and normally control-Y (\`\`^Y'') is the delayed-suspend character.

All echoing takes place at the remote site, so that (except for delays) the **rlogin** is transparent. Flow control via ^S/^Q and flushing of input and output on interrupts are handled properly.

## ENVIRONMENT

The following environment variable is utilized by **rlogin**:

- TERM

  Determines the user's terminal type.

## SEE ALSO

[rsh(1)](/rsh/1.md)

## HISTORY

The **rlogin** command appeared in 4.2BSD.

## BUGS

**Rlogin** will be replaced by [telnet(1)](/telnet/1.md) in the near future.

More of the environment should be propagated.
