Re: ping
You want a good tool, you'll have to write one :)
maybe the following code will help you out, thought is sends tcp pings.
it's real 0day so you might find bugs, but it works.
// TCP Port pinger
// code by rasta
#include stdio.h
#include stdlib.h
#include unistd.h
#include string.h
#include sys/types.h
#include sys/socket.h
#include netinet/in.h
#include arpa/inet.h
#include netdb.h
#include errno.h
extern int h_errno;
//#include net.h
#define PORT 80
#define NUMP 1
resolve(const char *host)
{
struct hostent *h;
struct in_addr inp;
if((inet_aton(host,inp))==0) {
if((h=gethostbyname(host))==NULL) {
herror(gethostbyname);
exit(1);
}
memcpy((void *)inp.s_addr,(const void *)h-h_addr,h-h_length);
}
return (inp.s_addr);
}
int main(int argc, char **argv)
{
int i, s, port, num, t, *tp;
struct sockaddr_in sock;
struct hostent *hostname;
port=PORT;
num=NUMP;
t=1; tp=t;
if(argc2) {
printf(usage: %s host [num pings] [port]\n,argv[0]);
exit(1); }
if(argc2) port=atoi(argv[2]);
if(argc3) num=atoi(argv[3]);
sock.sin_family=AF_INET;
sock.sin_port=htons(port);
sock.sin_addr.s_addr=resolve(argv[1]);
bzero((void *)(struct sockaddr *)sock.sin_zero,8);
for(i=0;inum;i++) {
if(!(s=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP))) {
perror(socket); exit(1); }
alarm(5);
if((connect(s,(struct sockaddr *)sock,sizeof(struct sockaddr_in)))==-1) {
perror(connect);
shutdown(s,2);
close(s);
exit(1);
}
printf(host is up\n);
shutdown(s,2);
close(s);
sleep(1);
}
return 0;
}

patching the original script sounds much more like what i need if i
don't find something else.
on the first look it might seem like ping -s on solaris is much better
than the default ping but thats not always the case.
lets assume that you need to get statistics on the status of the
network. statistics like, the host is up or down, just that no more than
that. what ping in solaris does is sending packets to a host until it
responds or until (i'm not sure) a certain time has been exceeded or X
packets didn't return. if one packet returns it's enough. in such cases
the solaris' ping is much more usefull and comfortable to use.

What i really wanted is to find out if you can get what the ping binary
in solaris does not a scripts to emulate it.
Is there such a tool for linux?
a script _is_ a tool. what is the problem iwth writing this script and
installing it somewhere on the system? if yo want, you can turn this into
a one-line perl script given to perl on the command line.
there is no difference between that and a binary program. btw, the way
'ping' behaves on linux by edfault is more useful then the way it does on
solaris (i.e. 'host is alive'? that's much less useful then what 'ping -s'
gives you on solaris).
btw, why do _you_ think the output on solaris is better then on linux? for
customer support via the phone? then tel the user to type 'ping -c 1' and
read the output to you.

Re: bind 9.1
Hi,
What do you mean the record has disappeared ?
What are the relevant logs entries tell you ? (tell us)
If you don't have requested that, you might not be able to see
any logging, or only minor ones.
put in your named.conf something like:
logging {
channel syslog_debug { syslog mail; severity debug 2;
print-category yes; };
channel syslog_client { syslog mail; severity debug 2;
print-category yes; print-severity yes; };
channel syslog_security { syslog mail; severity debug 2;
print-category yes; print-severity yes; };
channel syslog_notify { syslog mail; severity debug ;
print-category yes; };
channel syslog_xfar { syslog mail; severity debug 7;
print-category yes; };
channel syslog_general { syslog mail; severity debug 0;
print-category yes; print-severity yes; };
category default { syslog_debug; };
category general { syslog_general; };
category security { syslog_security; };
category config { syslog_notify; };
category xfer-in { syslog_notify; };
category xfer-out { syslog_xfar; };
category notify { syslog_notify; };
category client { syslog_client; };
category update { syslog_notify; };
category lame-servers { null; };
category resolver { null; };
category dispatch { null; };
};

Hi
I installed RH 7.1 with bind 9.1 which came with the cd, everything worked
fine for 2 weeks, today I saw that I do not have any dens resolution at all.
at the named.conf file I saw that it did not even load the zone file, the
record has disappeared !!
any one with a suggestion or experience with bind 9.1
