What is rsh and how to disable it? - Unix Linux Stack Exchange rsh is remote shell and it is unencrypted, that's why you should disable it I don't know which OS you are talking about, but for RHEL (like sr_ already stated) edit etc xinetd d rsh and set disable = yes After that restart xinetd and you're done Though I think, rsh should be disabled by default Instead of rsh use ssh
how to install rsh rlogin on RHEL 9 - Unix Linux Stack Exchange my guess would be to first try and scavenge the contents of ``rsh` and rsh-server-0 17-80 el7 x86_64 rpm from RHEL CentOS 7 If the existing rsh executable works then good otherwise build from source code getting the devel part of it from that part of the RHEL CentOS install –
linux - Command to trace rsh server to check behaviour of particular . . . That rsh is involved in calling it is completely irrelevant If you want to know what happens there, just look at what ulimit -u does You can analyze rshd until you are blue in the face, it won't ever do anything but (1) get the connection and check it is allowed, (2) collect the command to run, (3) fork exec to run the command, connected to
centos - rsh runs perfectly in normal user but not in root, very . . . Erradicate rsh immediately It is a huge security risk No, "this is just an internal network, there won't be any evil chinese hackers" is totally irrelevant, attacks are either automated (to recruit for botnets) or targeted, and the second ones are (depending on the statistics you want to believe) initiated by internal users in 80 to 95% of the cases

Why does `RSYNC_RSH` not work, but `--rsh` does? When you use this with --rsh, it connects to the server using the remote shell (e g ssh), but then uses rsyncd conf When you use this without--rsh, it tries to make an unencrypted network connection to the rsync server on TCP port 873 Setting RSYNC_RSH does not cause rsync "daemon" syntax to use a remote shell RSYNC_RSH is an "environment
Unable to do RSH connection - Unix Linux Stack Exchange I'm trying to do an RSH connection between these two Following are the errors which I'm getting: connect to address 172 21 70 95 port 544: Connection refused trying normal rsh ( usr bin rsh) poll: protocol failure in circuit setup One server was able to do the RSH connection to a third server when it was on another network
rsh shows poll: protocol failure in circuit setup, why? rsh is an exceptionally weird protocol which features one wrinkle that's quite unusual (I think non-PASV ftp is the only other TCP-based protocol I've seen it with): after opening a connection to the server, the server has to open a TCP connection back to the client
Why cant I use strace with rsh? - Unix Linux Stack Exchange If you want to trace rsh, you'll have to run strace as root Either let it run rsh as root, or pass the -u option so that the program runs with the privileges it normally has when started from your account: strace -o rsh strace -s9999 -u jhamb rsh localhost pwd
