    I'm running an IBM RT desktop with BSD 4.3-AFS.  When I try to
upload (using rz) to it via a serial connection at 9600 baud, I get a
screen full of error messages (ays16: overrun error and cbuf full) after
the first 200k of file transfer.  From the transmitting end, transfer
continues normally as the error messages scroll by on the RT console. 
However, when the transmitter reaches the end of the file, it backs up
and begins retransmitting the section of the file following the first
error message (i.e. everything after the first 200k).  The error
messages take longer to appear for slower speeds (i.e. after 400k has
been transmitted for 1200 baud connections).
    Does anyone know what's up?  If so, please let me know how to fix
this problem.

                            thanx,
                            Sam

HELP: Problem installing tcpip and sendmail

I hate it when it happens, but I have to re-install my AIX 2.2.1 again.
After I re-installed tcpip which used to work, ftp doesn't work anymore.
I can ftp from another machine to the RT, but not vice versa.  The error
message is: 
	gethostbyname (other_machine_name) failed

Also, sendmail which used to work, doesn't work anymore.  I can send email
out but when I tried to email from another machine to the RT, the message
bounced back with the error:
	RT_host_name Do not communicate with self
	<RT_host_name>... Service Unavailabel: No such file or directory

Can anyone help?  Thanks much.

(sendmail not working after reinstall): did you setup and rebuild sendmail.cf?
If you didn't put the hostname into sendmail.cf and rebuild it, then something
like you are describing will happen, as i recall.

Yes, I did.  I saved site dependent configuration files such as sendmail.cf
and net, reinstalled the software and reloaded the configuration files.
I also ran /usr/lib/sendmail -bz.

BTW, when I reinstalled sendmail, the directory /usr/adm/sendmail/aliasesDB
was missing, I had to create it manually.  I suspect that there is another
missing directory that I have to create.  Here is the content of the
/usr/adm/sendmail directory now:

total 120
-rw-rw----   1 root     system       511 Oct  9 14:35 aliases
drwxrwx---   2 root     system        64 Oct 12 09:30 aliasesDB
-rw-rw----   1 root     system         0 Oct 13 09:21 aliasesDBl
-rw-rw----   1 root     system      7108 Oct  9 14:35 sendmail.NOTES
-rw-r--r--   1 root     system     35553 Oct 13 09:18 sendmail.cf
-rw-rw----   1 root     system      4341 Oct 13 09:19 sendmail.cfDB
-rw-rw----   1 root     system         0 Oct 13 09:19 sendmail.cfDBl
-rw-rw----   1 root     system      1879 Oct  9 14:35 sendmail.hf
-rwxrwx---   1 root     system       919 Oct  9 14:35 smdemon.cleanu

Am I missing something?

Another possibility is that since I didn't reinstall all the operating
system utilities (small hard disk syndrome), I might have missed a utility
which is needed for ftp and sendmail.  I did reinstall:

	* base operating system
	* programming support
	* vi
	* gsl
	* sendmail
	* TCP/IP
	* inter-workstation commands (I added this later after I got
				these problems, is the order important?)

Thanks for looking into this.

 I've only got one more guess.. do you have to reconfigure the token ring stuff
like the submasks, etc (via 'devices' command i think)
 Maybe try getting the machine to boot 'clean' w/o starting tcpip, etc.. then
manually start tcpip and see if you get any error messages.  Also clean out the
error log first, then look at it (errpt -a) after the failures - is anything
logged? 
 I'm guessing, and i don't have an rt anymore.. so your mileage may vary..

good luck..
