Red Hat Bugzilla – Bug 2613
segmentation fault
Last modified: 2008-05-01 11:37:50 EDT
linuxconf core dumps with a segmentation fault. System is configured with two ethernet cards and acts as a DHCP server. After installation of RedHat 6.0, enabling the second ethernet card, and installing the DHCP rpm, and rebooting, linuxconf will core dump whenever run. A full reinstall and following the same steps reproduced the problem.
Further investigation reveals the cause: DHCPD was manually configured, and did not contain an entry of the form: server-identifier xxxxx; The lack of a "server-identifier" entry causes the segmentation violation at line 899 of dhcpedit.cc. Please note that this was not required for previous releases, and may affect other users who are upgrading. Also note that if multiple ranges for a subnet are specified, the linuxconf program will only display the last one of the group. An example of this would be: subnet 192.168.1.1 netmask 255.255.255.0 { range 192.168.1.10 192.168.1.100; range 192.168.1.110 192.168.1.200; } which would only display the range 110-200. -Rory
Linuxconf on a Toshiba 8000 laptop segfaults often, usually when trying to "accept" a feature during networking setup. It has segfaulted nearly 10 times as I have setup the RH6.0 laptop.
linuxconf also segfaults on my machine, even after reinstalling the package. 1024 # linuxconf Segmentation fault
linuxconf segfaults when launched, for me, too. I'm running RHL6.0 (Intel) on a Pentium or PII. DNS (resolver & BIND), IMAP, and SendMail are the only network services.
Reported fixed in linuxconf-1.16r1.3, released as update RHEA-1999:026
