use your usual package manager to know from where you got the binary and deduce where you can get the source. here is how with redhat (rpm packager): ------------------example----------------- [root@ozon upload]# which ping /bin/ping [root@ozon upload]# rpm -qf /bin/ping netkit-base-0.10-31 ------------------example----------------- So you see you have to get netkit-base-0.10-31.src.rpm to get the source. hope this helps pascal > -----Original Message----- > From: Shankar Vasudevan [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, September 29, 1999 11:08 AM > To: '[EMAIL PROTECTED]' > Cc: '[EMAIL PROTECTED]' > Subject: Ping Source Code -- Where can i find i > > > > Hi all, > > Where can i find 'C' Source code for ping > > thanx > shankar >
