I do not know the code, but had a look and suspect the limit is set using the IN_BUF define. Here is a proof of concept patch increasing the limit: diff --git a/sntop.h b/sntop.h index 173cbdf..e5e35b9 100644 --- a/sntop.h +++ b/sntop.h @@ -14,7 +14,7 @@ */ #define SNTOP_AUTHORS "Robert M. Love <r...@tech9.net>, Chris M. Rivera <cmriv...@ufl.edu>" -#define IN_BUF 33 /* size of our conf data vars and their input */ +#define IN_BUF 128 /* size of our conf data vars and their input */ #define CONF_BUF 256 /* size of path to conf data */ #define CONF_UFILE "/.sntoprc" /* name of user conf file .. we look for this in ~ first */ #ifndef CONF_SFILE I agree that dropping the config file line read limit is a good idea, but that would require a lot more rewriting than this simple oneliner. As far as I can tell, the rest of sntop do not care about host name lengths. Do you see a similar problem when passing the host name on the command line? If I understand the code correctly, you should not. Perhaps this issue can be fixed after 23 years? -- Happy hacking Petter Reinholdtsen
