I suggest you log in on console and vi /etc/services as root. You should be able to type in some basics to get the system back on its feet, then restore from tape or copy from another system.

For example:
telnet 23/tcp
login 513/tcp

I try to keep a hardcopy of files like this for just this occasion. :)

The /etc/services file is mainly used as a reference file only. If you can't telnet to your system, odd are that the inetd process is not running. Check the /etc/inetd.conf file for the services and then attempt to restart it. (/sbin/init.d/inetd start)
If it still does not start and there are no obvious error messages, make sure the contents of the /etc/rc.config/netdaemons are correct. The best way is compare it with another working system.

Further to my last note, if /etc/services is missing I wonder what else is missing from your system. Files do not delete themselves. Either you have a pooly written script, or someone with 'root' permissions has removed it (them). If you don't know for sure, change the 'root' password and check what jobs run from 'cron'.

to restore the services file you can get a default services file and modify as per your requirement from
/usr/newconfig/etc/services

I guess the question that has not been asked is what happened?

HP boxes don't just erase files. Its probably not a disk problem because /etc/services is on the root disk.

So, maybe the root filesystem is kind of full?

On 11.00 that tended to zero out files.

I'd restore the file from another system.

To get telnet and ftp working put the manual entries in the file from the earlier posts.

Best of Luck.

Hi,

You will need to have /etc/services for all the services that do getservent() calls. So, logon to the system from the console and copy /usr/newconfig/etc/services as /etc/services and restart inetd (inetd -c). Now atleast the basic services will work and you can either restore it from the backup or make modifications to suit to your environment.

Hi,

Login into the system by console
and copy the services file from /usr/newconfig/etc/ directory

Thanx
