RLOGIN(1)

🌸 RLOGIN 🌸 (section 1, the General Commands Manual)

okay bestie, sit down, hydrate, because we're logging into somebody else's computer over the network and it's giving vintage 💅. This page lives in the General Commands Manual, and it's about to be your whole personality for the next five minutes.

✨ NAME ✨

rlogin — remote login 🦋

---

🎀 SYNOPSIS 🎀

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

---

💖 DESCRIPTION 💖

So, what does rlogin actually do? It starts a terminal session on a remote host, host. That's it, that's the vibe. You type, the far-away computer listens. Iconic. 👑

Now, the auth tea ☕: rlogin first attempts to use the Kerberos authorization mechanism (described below, keep scrolling babe). And if the remote host doesn't support Kerberos? No stress — the standard Berkeley rhosts authorization mechanism gets used instead.

The options are as follows, and yes we're doing all of them, no skipping:

• -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. And when you use it together with the -8 option, you get a completely transparent connection. chef's kiss 🧑‍🍳
• -K — the -K option turns off all Kerberos authentication. Lowkey important caveat though: 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)) mode.
• -d — the -d option turns on socket debugging (see setsockopt(2)) 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.

Now for the escape-character lore, because this is where people get got 😭:

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.

not me explaining this twice so it actually sticks: escape char = ~ by default, delayed-suspend char = ^Y by default. periodt. 🫶

And the transparency bit: 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. slay. ✨

🌈 ENVIRONMENT 🌈

The following environment variable is utilized by rlogin:

• TERM — determines the user's terminal type. 🖥️

👑 SEE ALSO 👑

• rsh(1)

🦋 HISTORY 🦋

The rlogin command appeared in 4.2BSD. vintage fr fr.

💀 BUGS 💀

• rlogin will be replaced by telnet(1) in the near future. rip boo, we hardly knew ye 😭
• More of the environment should be propagated. (they said it, not me 🙈)

okay and that's the whole page, bestie!! mwah 💖 this was Linux NetKit (0.17), dated August 15, 1999 — yes, a 1999 baddie, and it still ate. go log into something remote, stay safe, and remember: tilde-dot to dip. 💅✨
