getty: cannot open "ttyd1p0". errno: 25

Joseph Suggs — Fri, 18 Apr 2008 20:13:28 GMT

HP-UX 11i running on HP C8000. We cannot transfer files to the C8000 using ftp, it is interrupted. File syslog.log has:

ftpd[4923]: FTP session closed
getty: cannot open "ttyd1p0". errno: 25

Device ttyd1p0 does exist in file /etc/inittab, but I believe it does not exist under /dev. If confirmed, what is wrong and how can I fix it ?

Thanks.

Can you post the below:

lsdev|grep tty
grep tty /etc/inittab
ll /dev/ttyd*
lssf /dev/ttyd1p0

Regards,
Rasheed Tamton.

How is the getty "listen" on a serial port related to your FTP problem? No clue ...

Thank you for replying, but I need suggestions to fix, not the causes (I guess some stupid admin was playing with devices).

Thank you.

The only related information you gave us is this:

1)ftpd[4923]: FTP session closed
2)getty: cannot open "ttyd1p0". errno: 25

1) totally normal, just information

2) related to the getty, NOT ftp !

Since the getty is not related to ftp, what exactly is your problem?

If you try from this system

# ftp 127.0.0.1

what happens?

All FTP transfers to C8000 are interrupted a few seconds after you hit PUT . And for every interrupted transfer I can see the message

getty: cannot open "ttyd1p0". errno: 25

in syslog.log. I know that sounds odd, but it is the only clue I have.
Transfers from C8000 to a external equipment are fine. Thanks.

What is the output of:
grep ftp /etc/inetd.conf
whereis ftpd
ll /usr/lbin/ftpd

Can you use sftp if you have ssh installed for troubleshooting and see what result you get.

Regards.

OldSchool — Wed, 23 Apr 2008 16:14:49 GMT

are the file transfers being done from a command line, or is it a scripted transfer?

If scripted, please post script and how it is being run, ie if from cron, show the crontab entry that's running it

Re: getty: cannot open "ttyd1p0". errno: 25

Joseph Suggs — Thu, 24 Apr 2008 17:19:14 GMT

It is command line.
