Activating rcp or rsync ports

[Chern Jian Leaw]

HI ,

Is there a way to check if a port for a particular network service i.e rcp, rsync, rsh, rlogin, etc ?

I tried performing a rsync task between 2 machines, and I obtain the error message below:
On host1:
rsync -avz test.cc host2.willow.com:/home/cs/kenny
Permission denied
unexpected EOF in read_timeout

However, when I invoked rsync from host2 to copy the file to host1 and it worked:
On host2:
rsync -avz myfile.cc host1.pdx.willow.com:/home/cs-pg/ken
building file list ...done
myfile.cc
wrote 113 bytes read 36 bytes 42.57 bytes/sec
total size is 10 speedup is 0.07

I've included the host and user name entries on both .rhost files on both machines in the home directories, and not in /.

host1 and host2 are on 2 separate NIS domains.

I get the same kind of error when I tried copying files with rcp.

As for rsh:
On host1:
rsh host2..willow.com
Password:
it prompted for a password even though host1 and host2 have been made to trust each other.

Could anyone please show me how I could open up the port on host2 to accept incoming data from host1?

Could anyone please help me out on this matter?

Thanks.

you have something wrong somewhere.

What's the OS's???

Compare your

/etc/services

files.

Put + + in the first line of .rhosts just to test the proper routing and account login. Then of course delete it after your test.


Also, lsof, is a great tool to view what a process has open, but I don't see much of a use here.

harry,

I tried placing + + entry into both the .rhosts file:
On host2:
#cat .rhosts
+ +
host1.pdx.willow.com ken

On host1:
# cat .rhosts
+ +
hosts2.willow.com ken

This method does not seem to work.
Could you please tell me where did I go wrong?

I was wondering if you could provide an example on how I could use lsof to check if the rsync port is open on both host machines?

Thanks

harry,

The /etc/services file on both host1 and host2 have had their rsync ports enabled i.e

On host1:
#cat /etc/services
rsync 873/tcp
rsync 873/udp

On host2:
#cat /etc/services
rsync 873/tcp
rsync 873/udp

I did not have rcp or rsh port enabled on both host1 and host2 in the /etc/services. However, even without the rsh or rcp ports enabled, I'm able to invoke rsync on other machines, except host1 and host2.

I invoked rsync on HPUX B-11 machines.

Thanks.

Are you by chance trying the transfer as root? Look at your host1 system's sshd_config file. I experienced the same problem you are describing and I commented out the "PermitRootLogin" line to enable root to perform the rsync operation. Good Luck!
