On the machine from which the output has been taken:

Code:
 > uname -srv
HP-UX B.11.23 U

I'm not making it up - the results are absolutely copied & pasted from the live server I happen to be working on at the moment - I'll try it elsewhere when I have the opportunity.

Same thing:

X25 Address - A challenge...

Okay - I've been searching near and far for the answer to this seemly simple question..... how do I find the X25 address for a server. Is there some sort of dump or ping or even a config which would tell me the address. I can find nothing on the web and my colleagues can't help either. (1 Reply)

logsave

LOGSAVE(8)						      System Manager's Manual							LOGSAVE(8)

NAME

       logsave - save the output of a command in a logfile

SYNOPSIS

       logsave [ -asv ] logfile cmd_prog [ ... ]

DESCRIPTION

       The  logsave  program  will  execute  cmd_prog with the specified argument(s), and save a copy of its output to logfile.  If the containing
       directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out.	A copy of the output  will
       also be written to standard output.

       If  cmd_prog  is a single hyphen ('-'), then instead of executing a program, logsave will take its input from standard input and save it in
       logfile

       logsave is useful for saving the output of initial boot scripts until the /var partition is mounted,  so  the  output  can  be  written	to
       /var/log.

OPTIONS

       -a     This option will cause the output to be appended to logfile, instead of replacing its current contents.

       -s     This  option  will  cause  logsave  to  skip writing to the log file text which is bracketed with a control-A (ASCII 001 or Start of
	      Header) and control-B (ASCII 002 or Start of Text).  This allows progress bar information to be visible to the user on the  console,
	      while not being written to the log file.

       -v     This option will make logsave to be more verbose in its output to the user.
